The disease is more common in adults than in children; average age at diagnosis is more than 65 years.</span><br /><br /><span style="color: rgb(204, 51, 204); font-weight: bold; font-style: italic;">Treatment of AML often begins with induction therapy (initial treatment) that includes chemotherapy to produce a complete remission (defined as the disappearance of leukemia cells in the bone marrow and normalization of the white blood cell, red blood cell, and platelet levels). After induction therapy, patients generally receive additional treatment (consolidation therapy) to reduce the likelihood of leukemia recurrence. Depending upon prognosis, age of the patient, and/or other existing medical conditions, consolidation therapy can range from extremely aggressive to less aggressive.</span><br /><br /><span style="color: rgb(204, 51, 204); font-weight: bold; font-style: italic;">An allogeneic stem cell transplant, considered an extremely aggressive treatment option, involves the use of high doses of therapy, which kill a greater amount of cancer cells than standard doses. Unfortunately, the high doses of therapy also cause a significant reduction in blood cells, resulting in a patient's susceptibility to infection, bleeding, and the need for blood transfusions. Often, the infections caused by these high doses of therapy are life-threatening.</span><br /><br /><span style="color: rgb(204, 51, 204); font-weight: bold; font-style: italic;">To restore levels of blood cells</span></span><span style="color: rgb(204, 51, 204); font-weight: bold; font-style: italic;font-size:130%;" class="fullpost" >stem cells, which are immature blood cells, are collected from a donor and infused into the patient following high-dose therapy. These donor stem cells can also mount an attack against the patient's cancer cells. Unfortunately, these donor cells can also attack a patient’s healthy cells, causing a potentially life-threatening condition called graft-versus-host disease (GVHD). Stem cells donated by a relative (related donor) tend to carry a lower risk of GVHD than those from an unrelated donor.<br /><br />A drawback of an allogeneic stem cell transplant is that treatment-related mortality and side effects can be substantial; researchers have thus focused on curative options that are more easily tolerated. However, for patients with very aggressive AML and those who are younger, an allogeneic stem cell transplant still appears to provide optimal outcomes.<br /><br />Researchers affiliated with the International Blood and Marrow Transplant Registry recently conducted a clinical study evaluating the use of allogeneic stem cell transplants with unrelated donors for patients with AML. This trial included 261 patients with AML in first remission (when disease is undetectable for the first time following treatment) or second remission (the second time following two different treatment courses that disease is undetectable) who were 60 years of age or younger. Patients in this trial were divided into three groups: those who had a high, intermediate, or low risk of developing a cancer recurrence following standard therapies.<br /><br />The following results include patients in first remission:<br /><br />• At five years overall survival was between 29–30% for all groups of patients.<br />• At five years mortality related to treatment was 47% for patients at a high risk of developing a recurrence, 53% for patients at an intermediate risk of developing a recurrence, and 63% for patients at a low risk of developing a recurrence.<br />• Cancer recurrence rates were 8%, 17%, and 26%, respectively for patients with low, intermediate, and high risks of developing a cancer recurrence.<br /><br />The following results include patients in second remission:<br /><br />• At five years overall survival was 45%, 37%, and 36%, respectively, among patients with a low, intermediate, and high risk of developing a cancer recurrence.<br />• At five years mortality related to treatment was 46%, 46%, and 30%, respectively among patients with a low, intermediate, and high risk of developing a cancer recurrence.<br />• Cancer recurrence rates were 12%, 18%, and 32%, respectively, among patients with a low, intermediate, and high risk of developing a cancer recurrence.<br /><br />The researchers concluded that an unrelated allogeneic stem cell transplant can provide AML patients 60 years of age or younger who are in first remission and have a high risk of a cancer recurrence overall survival rates at five years that are comparable to those among patients with a lower risk of a recurrence. However, this trend did not seem to hold true for patients in second remission. Furthermore, mortality related to treatment was high.<br /><br />Patients with AML who are at a high risk of developing a cancer recurrence and do not have a related donor for an allogeneic stem cell transplant may wish to speak with their physician regarding their individual risks and benefits of an unrelated stem cell transplant.<br /><br />Reference: Tallman MS, Dewald GW, Sandham S, et al.

Several studies have suggested that vitamin supplementation during pregnancy can prevent birth defects. There have also been associations established between vitamin supplementation and the child’s risk of acute lymphoblastic leukemia and brain tumors. In addition, research has suggested that the widespread use of vitamin supplementation in pregnant women has helped decrease the incidence of childhood medulloblastoma and neuroblastoma.</span><br /><br /><span style="color: rgb(51, 0, 153); font-style: italic; font-weight: bold;">In the current study, researchers </span><br /></span><span style="color: rgb(51, 0, 153); font-style: italic; font-weight: bold;font-size:130%;" class="fullpost" >from the University of Toronto conducted a literature review of materials produced between 1960 and 2005. A meta-analysis was performed of data from seven studies to determine the relationship between maternal vitamin intake and childhood cancer incidence. All vitamins evaluated included folic acid. The following comparisons were made between children of women who received vitamin supplements containing folic acid during pregnancy and those who did not:<br /><br /> * There was a 36% reduction for pediatric leukemia; an 18% reduction in pediatric brain tumors; and a 47% reduction in neuroblastoma in children of women taking vitamin supplements.<br /> * It was estimated that, in the U.S., vitamin supplementation during pregnancy could prevent 900 cases of pediatric leukemia and 300–400 cases of pediatric brain tumors annually.<br /><br />These authors stated that it was not know specifically which vitamins were responsible for these effects. They did speculate, however, that folic acid may be responsible for this decreased risk pediatric brain tumors, neuroblastoma, and leukemia. Women who are pregnant may wish to speak with their physician regarding prenatal vitamin supplementation.<br /><br />Reference: Goh YI, Bollano E, Einarson TR, et al.

The pancreas helps the body to break down food and also produces hormones, such as insulin, to regulate the body’s storage and use of food.</span><br /><br /><span style="color: rgb(51, 0, 153); font-style: italic; font-weight: bold;">Pancreatic cancer has one of the highest mortality rates of all cancers. It accounts for approximately 2% of all newly diagnosed cancers in the United States each year but 5% of all cancer deaths. Pancreatic cancer is often called a “silent killer” because its symptoms are usually not recognizable until it has advanced and spread outside the pancreas. As a result the majority of pancreatic cancers are not diagnosed until they have reached advanced stages and are considered incurable.</span><br /><br /><span style="color: rgb(51, 0, 153); font-style: italic; font-weight: bold;">If pancreatic cancer has not spread to surrounding or distant organs, it is usually considered operable. Historically, patients have been treated with surgery followed by chemotherapy and/or radiation to destroy any micrometastases (cancer cells that have spread outside the pancreas). New research indicates, however, that neoadjuvant radiation therapy (radiation delivered prior to surgery) might offer greater benefit to patients because it can potentially shrink the tumor prior to surgery, thereby ensuring a better chance of removal. Furthermore, because pancreatic surgery </span><br /></span><span style="color: rgb(51, 0, 153); font-style: italic; font-weight: bold;font-size:130%;" class="fullpost" ><br />is so invasive, many patients are in no condition to undergo radiation treatment after surgery, so neoadjuvant treatment allows them to receive radiation that they might not receive otherwise.<br /><br />Researchers from the Weill Cornell Medical College used data from the Surveillance, Epidemiology, and End Results (SEER) registry database to perform a retrospective analysis on patients who had surgically resected (removed) pancreatic cancer between 1994 and 2003. The researchers compared the overall survival rates among patients who received neoadjuvant radiation, adjuvant radiation, or no radiation. Patients who received neoadjuvant radiation survived 23 months, compared with 12 months for patients who did not receive radiation and 17 months for those who received adjuvant radiation (following surgery).<br /><br />The researchers concluded that neoadjuvant radiation therapy offers a significant benefit over surgery alone or surgery with adjuvant radiation therapy in treating pancreatic cancer. Research will likely be ongoing to further explore these findings.<br /><br />Reference:<br />[1] Stessin AM, Meyer JE, Sherr DL.

The results are combined to calculate her overall 'absolute risk' of breast cancer, according to the company, BreastHealthUK.</span><br /><br /><span style="color: rgb(204, 51, 204); font-style: italic; font-weight: bold;">The gene test is provided by Icelandic company deCODE genetics and is carried out using a sample of DNA extracted from a mouth swab.</span><br /><br /><span style="color: rgb(204, 51, 204); font-style: italic; font-weight: bold;">*With more and more commercial genetic screens emerging, there's an urgent need for well-designed studies evaluating these types of tests.*</span><br /><br /><span style="color: rgb(204, 51, 204); font-style: italic; font-weight: bold;">- Dr Lesley Walker, director of cancer information, Cancer Research UK</span><br /><br /><span style="color: rgb(204, 51, 204); font-style: italic; font-weight: bold;">It looks at seven gene variations - or SNPs - that are associated with an increased risk of breast cancer, several of which were discovered by Cancer Research UK scientists.</span><br /><br /><span style="color: rgb(204, 51, 204); font-style: italic; font-weight: bold;">It combines these with results from a lifestyle risk calculation programme called the Tyrer-Cuzick model, also developed by Cancer Research UK-funded scientists.</span><br /><br /><span style="color: rgb(204, 51, 204); font-style: italic; font-weight: bold;">Women are then presented with the results in consultation with an experienced breast surgeon or genetic counsellor, so that</span></span><span style="color: rgb(204, 51, 204); font-style: italic; font-weight: bold;font-size:130%;" class="fullpost" >their genetic and lifestyle risk factors can be discussed and the implications fully explained.<br /><br />The test is not available on the NHS but can be obtained privately for ?700.<br /><br />Breast surgeon Professor Gordon Wishart, medical director of BreastHealth UK, commented: "Although genetic testing is still a relatively young technique, when combined with proven methods to elicit lifestyle and family history factors, it can provide breast surgeons with new insights into detection and prevention of this disease."<br /><br />However, experts pointed out that there is still a long way to go before the genetics of breast cancer is fully understood, and that research is needed to prove that these commercial tests will actually reduce cancer death rates.<br /><br />Dr Lesley Walker, Cancer Research UK's director of cancer information, commented: "Assessing your risk of cancer and interpreting the results of genetic tests is a very complex matter. With more and more commercial genetic screens emerging, there's an urgent need for well-designed studies evaluating these types of tests - we need to know more about their clinical and psychological impacts, and their current scientific value."<br /><br />Dr Walker continued: "We've still only got a few pieces of the genetic puzzle. Genetic testing without this missing information means we risk worrying women who may never develop the disease. The commercial market for genetic testing should be properly regulated and appropriate information on the pros and cons should be conveyed to customers.<br /><br />"At this stage, Cancer Research UK would recommend that women worried about their risk of cancer visit their GP or contact Cancer Research UK's information nurses on 0808 800 4040. Women with a strong family history of breast cancer will be offered genetic testing on the NHS."<br /><br />Women with a strong family history of breast cancer are already eligible for genetic testing on the NHS. According to guidelines published by the National Institute for Health and Clinical Excellence (NICE), women can be referred to specialist genetics services if they have a high risk of developing breast cancer.<br /><br />This risk is usually determined by looking at a number of factors, including the age at which close relatives were diagnosed with breast cancer; whether a relative had cancer in both breasts; and whether any men in the family have had breast cancer.</span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-39666257725914107782009-02-02T18:11:00.000-08:002009-02-02T18:17:04.798-08:00Study sheds light on cancer-causing gene<span style="font-size:130%;"><span style="color: rgb(204, 102, 204); font-style: italic; font-weight: bold;">US scientists have discovered a previously unknown way by which a cancer-causing version of the Myc gene speeds up the progression of the disease.</span><br /><br /><span style="color: rgb(204, 102, 204); font-style: italic; font-weight: bold;">A faulty version of Myc is already known to interfere with the early stages of DNA activity in the nucleus of the cell.

It is therefore vital that women are aware of the symptoms to look out for," said Dr Zorbas.<br /><br />The symptoms of ovarian cancer include:<br /><br />- abdominal bloating<br />- abdominal or back pain<br />- appetite loss or feeling full quickly<br />- changes in toilet habits<br />- unexplained weight loss or gain<br />- indigestion or heartburn<br />- fatigue<br /><br /> The most common symptoms, experienced by half of the study participants, were abdominal symptoms such as fullness and pain. Bloating, bowel or urinary symptoms were reported by approximately one third of participants.<br /><br />"We know many women will experience these symptoms as part of everyday life," said Dr Zorbas. "But if any of these symptoms are unusual for you and they persist, it is important to see your doctor. No one knows your body like you do."<br /><br />This year about 1300 women will be diagnosed with ovarian cancer in Australia. More than half of women diagnosed do not survive five years after their diagnosis. More than 70 per cent of women are diagnosed at an advanced stage, where the cancer has spread and is difficult to treat successfully.<br /><br />National Breast and Ovarian Cancer Centre is funded by the Australian Government and works with consumers, health professionals, cancer organisations, researchers and governments to improve care and cancer control in breast and ovarian cancer.

"With it, dentists will be able to catch cancers before a woman can feel a lump."Researchers have discovered that the onset of </strong></em></span><a href="http://www.naturalnews.com/breast_cancer.html"><span style="font-size:130%;color:#cc33cc;"><em><strong>breast cancer</strong></em></span></a><span style="font-size:130%;color:#cc33cc;"><em><strong> changes the density of different proteins excreted by the salivary glands. In the current study, published in the journal Cancer Investigation, Streckfus and other researchers from the UT-Houston Dental Branch and Medical School compared the protein levels found in the </strong></em></span><a href="http://www.naturalnews.com/saliva.html"><span style="font-size:130%;color:#cc33cc;"><em><strong>saliva</strong></em></span></a><span style="font-size:130%;color:#cc33cc;"><em><strong> of 10 women with breast </strong></em></span><a href="http://www.naturalnews.com/cancer.html"><span style="font-size:130%;color:#cc33cc;"><em><strong>cancer</strong></em></span></a><span style="font-size:130%;color:#cc33cc;"><em><strong>, 10 healthy women and 10 women with a type of tumor called fibroadenoma.Fibroadenoma is the most common kind of benign breast tumor."Saliva is a complex mixture of proteins," said researcher William Dubinsky. "We go through a process that compares different samples by chemically labeling them in such a way that we can not only identify the protein, but determine how much of it is in each sample. This allows us to compare the levels of 150-200 different proteins in cancerous versus non-cancerous specimens to identify possible markers for </strong></em></span><a href="http://www.naturalnews.com/disease.html"><span style="font-size:130%;color:#cc33cc;"><em><strong>disease</strong></em></span></a><span style="font-size:130%;color:#cc33cc;"><em><strong>."The researchers identified 49 proteins that were present at different levels between the three groups. These proteins should hypothetically allow doctors to use such a saliva test to alert them when a woman has a tumor, and to determine whether it is cancerous or benign."This is a unique finding," Streckfus said, "as it targets both the benign and malignant tumor, which could potentially reduce the number of false positives and false negatives associated with current cancer diagnostics".Previously, the same team of researchers was able to correctly detect whether a woman had breast cancer 85 percent of the time, using only one saliva protein as a marker. With 49 different markers, Streckfus says that the accuracy of the test should be closer to 95 percent.In the current method, the saliva sample is placed onto a hand-held, gold-plated chip or lab dish, developed by UT-Austin biochemists. A laser analyzes the protein content of the sample."I see this as a future public health service by </strong></em></span><a href="http://www.naturalnews.com/dentists.html"><span style="font-size:130%;color:#cc33cc;"><em><strong>dentists</strong></em></span></a><span style="font-size:130%;color:#cc33cc;"><em><strong>," Streckfus said. "Most folks, especially women and children, visit the dental office way more often than they ever see the physician. Saliva is a non-invasive, quicker way for detection."Many obstacles remain before this test could be available, however. The first step is more studies to confirm the effectiveness of the protein markers as diagnostic tools in a larger group of patients. Streckfus and colleagues hope to launch a large, multicenter clinical trial of the test within the next two years, and to apply for FDA approval within five.The only saliva test currently approved by the FDA is one for HIV/AIDS.A saliva test for breast cancer has many advantages over current diagnostic methods such as ultrasounds, mammograms, biopsies and </strong></em></span><a href="http://www.naturalnews.com/blood_tests.html"><span style="font-size:130%;color:#cc33cc;"><em><strong>blood tests</strong></em></span></a><span style="font-size:130%;color:#cc33cc;"><em><strong>. It would be far less invasive and expensive than most such tests, and have a much higher accuracy rate than blood tests, which are not currently favored for breast cancer diagnosis due to their poor accuracy.The higher accuracy of a saliva test comes in part from the fact that saliva proteins are much easier to detect than the proteins in blood, Dubinsky said."In the case of breast cancer, saliva analysis has been used to monitor patient response to chemotherapy or surgical treatment of the disease," said Professor Damien Walmsley, scientific adviser for the British Dental Association.

Because women are exposed to X-ray radiation as part of the mammogram procedure, regular mammogram use actually increases women's risk of developing various cancers. For this reason, mammograms are not normally performed for women under the age of 40, in whom the risk of breast cancer is relatively low unless symptoms are present.But Streckfus warned that a saliva test cannot utterly replace mammograms, because the saliva test is unable to determine which breast contains the tumor.Nonetheless, cancer patient advocates have greeted the new research as promising. According to Leonard Lichtenfeld, deputy chief medical officer for the American Cancer Society, the saliva test will one day be "a terrific advance.""I think advances like this test portend the day when we'll be able to diagnose disease that would be invisible using today's technologies," Lichtenfeld said. "[Patients will] be able to be diagnosed and treated before they would otherwise know they have the disease."Streckfus and colleagues are also researching whether saliva tests can be used to diagnose other cancers, including of the cervix, uterus, head, neck and ovaries. Another group of researchers, at Johns Hopkins Kimmel Cancer Center, is also working on a saliva test for head-and-neck cancer. According to Lichtenfeld, the Johns Hopkins team is farther along than the UT-Houston team, because their test relies on genetic rather than protein markers.</strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-82614505303794272712009-01-31T12:03:00.000-08:002009-01-31T12:04:10.922-08:00Bras Shown to Cause Cancer<span style="font-size:130%;color:#339999;"><em><strong> Is it possible that wearing a bra can actually cause cancer? Studies show that this is a very real possibility. The reason is that regularly wearing a bra prevents lymph drainage and circulation, which can greatly increase the possibility of developing breast cancer.The lymphatic and circulatory systems are responsible for both delivering vital nutrients and clearing out toxins. When the body does not have access to nutrients or when it is under the attack of toxins, cancer may develop.A study published in the European Journal of Cancer studied factors for breast cancer such as breast size and handedness. They discovered that premenopausal women who do not wear bras are less than half as likely to get breast cancer that those who regularly wear a bra. A study conducted by researcher David Moth revealed that even the lightest bras place pressure on the lymphatic system.Other research published in Chronobiology International in 2000 discovered that regular bra wearing decreases the production of melatonin, which is a potent natural antioxidant and the hormone that regulates sleep, boosts the immune system and, incredibly fights aging. Balanced melatonin levels are essential for the body to fight many types of cancer, including breast cancer.Researchers Singer and Grismaijer observed 4,500 women and their bra wearing practices. An amazing 3 out of 4 women who wore their bras 24 hours per day developed breast cancer. Women who wore their bras more than 12 hours per day had a 1 in 7 chance of getting breast cancer. 1 out 152 women who wore their bra less than 12 hours a day got breast cancer and an incredibly low 1 out of 168 women who rarely or never wear a bra developed breast cancer.These same researchers studied the indigenous populations of New Zealand and Australia. The Maoris, who are indigenous to New Zealand, are basically fully integrated into mainstream New Zealand life and interestingly have the same chances of developing breast cancer. The aboriginals of Australia on the other hand have not integrated into regular western society and do not regularly wear bras, and have practically no breast cancer. Japanese, Fijians, and many women from other cultures were found to have a significantly higher chance of developing breast cancer when they began wearing bras.It may be interesting to note that a very small proportion of men do develop breast cancer, exactly the same amount as women who go braless!European, Journal of Cancer 1991 ;27(2): 131-5.Cancer is Not a Disease by Andreas Moritz</strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-66106626415237103842009-01-31T11:59:00.000-08:002009-01-31T12:00:55.393-08:00Brussels Sprouts Defend against All Types of Cancer<strong><em><span style="font-size:130%;color:#cc66cc;">Plant phytonutrients found in Brussels sprouts boost the body`s natural defense systems to protect against cancer and other diseases. Brussels sprouts and other cruciferous vegetables disarm cancer causing chemicals and encourage the body`s detoxification enzymes.Evidence in the Netherlands suggests that Brussels sprouts keep the body free from cancer by promoting healthy DNA. DNA is responsible for cell division in the body. When DNA gets damaged, cells may begin to replicate much more rapidly than normal, which can cause a cancerous tumor to begin to form. Several studies reveal that Brussels sprouts have the ability to help protect DNA from damage.Researchers compared two groups of healthy men. Half of these men ate 300 grams of Brussels sprouts daily, while the other men didn`t have any cruciferous vegetables in their diet. After three weeks, the men who ate their daily dose of Brussels sprouts had a 28% decrease in measured DNA damage.Diminish Digestive Cancers with Brussels SproutsThe phytonutrients in Brussels sprouts have been shown to protect against heterocyclic amines, which are the carcinogenic compounds found in grilled and charbroiled meat. These carcinogens are particularly associated with colon cancer. The study, published in Carcinogenesis, found that animals that were given Brussels sprout juice and heterocyclic amine carcinogen were less likely to develop the cancer.The animals given Brussels sprouts had a reduction in pre-cancerous cells in the colon of 41-52% in the colon and 27-67% in the liver, and drastically diminished the size (85-91%) of pre-cancerous lesions in the liver. These amazing results seem to be a result of Brussels sprouts potent ability to detoxify the body and clear out the colon.Brussels sprouts are also packed with fiber, which nourishes the cells lining the walls of the colon and prevents colon problems including cancer.Brussels Sprouts Fight Bladder CancerResearch published in the International Journal of Cancer shows that Brussels sprouts protect against bladder cancer. The diets of 697 people who were recently diagnosed with bladder cancer were compared with 708 people with the same age, gender and ethnicity who were healthy. The average daily intake of Brussels sprouts and other cruciferous vegetables was significantly lower in those with bladder cancer than in their healthy counterparts. Those who had the highest intake of Brussels sprouts and cruciferous vegetables had a 29% lower risk of bladder cancer that those who ate the least.The benefits of these vegetables were highest in those who have the highest risk of bladder cancer, including men, smokers and older individuals.Brussels sprout`s bladder cancer properties appear to come from their high levels isothiocyanates, which are potent anti-carcinogens. Isothiocyanates travel through the bladder to be excreted, making them particularly powerful against this form of cancer.Breast Cancer ProtectionSulforaphane is released by Brussels sprouts and has been proven to trigger the liver to produce enzymes that detoxify the body of cancer-causing chemicals They have been shown to inhibit chemically-induced breast cancers in animal studies. Research published in the Journal of Nutrition shows that sulforaphane can halt the proliferation of breast cancer cells, even in the later stages of their growth.Defend Against Prostate CancerResearch at Fred Hutchinson Cancer Research Center in Seattle studied 1,000 men. It was shown that eating 28 servings of different vegetables a week reduced their risk of prostate cancer by 35%. But those who ate 3 or more servings of cruciferous vegetables each week had a 44% lower prostate cancer risk.Many people claim to not enjoy eating Brussels sprouts. If you are not a fan of this incredible food, try chopping them up into tiny peices and sprinkling them over a salad. You won`t even be able to taste them but you will still get the health enhancing benefits and defend your body against disease.</span></em></strong><a href="http://www.whfoods.com/" target="_blank"><strong><em><span style="font-size:130%;color:#cc66cc;">http://www.whfoods.com</span></em></strong></a><a href="http://www.drbriffa.com/" target="_blank"><strong><em><span style="font-size:130%;color:#cc66cc;">http://www.drbriffa.com</span></em></strong></a>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-48703743028884510332009-01-31T11:56:00.000-08:002009-01-31T11:58:53.053-08:00Apple Pectin Helps Prevent Colorectal Cancer<span style="font-size:130%;color:#00cccc;"><strong><em>The pectin from apple peels and extracts of apple juice appear to increase the production of a chemical associated with protection from colon cancer, according to a new study conducted by German researchers and published in the journal Nutrition.<br /><br />The researchers fermented fecal slurry from healthy volunteers with either apple pectin, apple juice extract, or a combination of the two. They found that the concentrations of a short chain fatty acid (SCFA) known as butyrate were higher in the samples that had been fermented with apple pectin. Concentrations of other SCFAs were also elevated.<br /><br />"Butyrate not only serves as a major nutrient for the colon epithelia [lining] but is also thought to play an important role in the protective effect of natural fiber against colorectal cancer," the researchers wrote.<br /><br />Butyrate appeared to inhibit the production of histone deacetylases (HDAC), which have been linked to the development of precancerous cells and tumors. When the researchers tested the fermented fecal slurries on both healthy and cancerous colon cells, they found that the production of HDAC was significantly inhibited.<br /><br />The slurries fermented with apple juice did not have butyrate levels as high as those fermented with pectin, but they inhibited HDAC production just as effectively. A combination of pectin and apple juice, however, was no more effective than pectin alone. This led the researchers to hypothesize that while apple juice contains still-unknown HDAC inhibitors other than butyrate, butyrate is the most significant inhibitor for the human body.<br /><br />The study is part of a growing interest in the cancer-suppressing qualities of fruits and vegetables. Another recent study found that freeze-dried grape powder appears to hamper the development of colorectal cancer cells. This effect is believed to arise from the chemical resveratrol, rather than from pectin. But researchers have noted that the cancer-fighting properties of fruits and vegetables often arise from complex interactions between different ingredients.<br /><br />Sources for this story include: www.foodnavigator-usa.com.</em></strong></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-77149859153333844712009-01-28T07:03:00.000-08:002009-01-28T07:04:48.748-08:00Breast Cancer Gene-Free Baby Is Dangerous Sign of New Era of Eugenics, Genetic Class Wars<em><strong><span style="font-size:130%;color:#00cccc;">The era of pre-birth genetic screening of babies has commenced.

Because despite all the grand technology, the manipulation of human life and the arrogant playing God that takes place daily in the minds of western doctors, there's one thing they still haven't figured out how to do: Tell the truth to a patient about how they can prevent cancer, regardless of their genes.Modern medicine is a huge technical success and a complete humanistic failure. It offers the most impressive technology in the world and puts it into the hands of the most ethically-deficient professionals who are so pessimistic about the nature of reality that they don't even believe in the existence of their own souls.And do you really want scientists who don't even believe in the existence of the human soul to be playing God with your baby's genes?Disturbing.It should also be noted, by the way, that this whole process of "gene screening babies" involves testing the embryo at the eight-cell stage (when conception has already taken place and the baby is beginning to grow), and then throwing away any embryos that don't fit the desire genetic profile.In effect, the gene screening of babies involves the systematic destruction of viable human embryos that could grow into full-fledged babies. This opens up a whole new debate on the issue of abortion, of course, and I'd like to hear your comments on all this. Simply post your thoughts in the comment section below.The key issues are: At what point is the genetic screening of a baby going too far? Most people might agree, for example, that screening for major birth defects is acceptable, but is it acceptable to screen for things like blue eyes and then toss out the embryos that don't carry that gene?What will happen in the future of society if the gene screening of embryos becomes socially acceptable and is embraced by parents?What are the risks posed by a race of beings that engages in routine genetic selection? (For example, might be lose biodiversity? Might the BRCA1 gene have another positive purpose that doctors haven't identified yet?)Should humans be genetically engineered to insert new traits? Larger brains? Stronger muscles? Bigger boobs? (Parents could actually order up a boob job on their daughter before she's born!)Think carefully about this one.

This protective effect, however, only applied to women who were in the normal weight range.About Breast CancerIn 2004, over 185,000 women and more than 1,800 men in the United States alone were diagnosed with breast cancer, while almost 41,000 women and 362 men succumbed to the disease.In that year, breast cancer was the number two cancer killer of American women, ranked only after non-melanoma skin cancer, while also being their number five killer overall. In addition, for Hispanic women, breast cancer was the number one cancer killer.In Canada, the picture isn't much better either. Among Canadian women, breast cancer is the most common form of cancer. The Canadian Cancer Society has estimated that some 22,400 women will be diagnosed with it this year, while about 5,300 will succumb to the disease.Details of StudyExercise has already been heavily linked with the prevention of many chronic diseases. Also, previously, other studies had suggested that women who went through more physical activity had lower risks of getting breast cancer. But this time, the researchers dug deeper.In this study, conducted by the National Cancer Institute of the US National Institutes of Health, more than 32,000 women from across the United States were tracked for a period of 11 years. The average age of the subjects was 61, and all of them were free from chronic diseases at the start of the study. The participants were made to fill out a detailed questionnaire regarding their physical activity.The survey asked the participants to estimate the typical number of hours which they spent each day carrying out various physical activities. These included moderate activities such as bowling, gardening, hiking, jogging lightly, mowing the lawn, vacuuming the floor and walking.They also included vigorous activities such as aerobics, chopping wood, competitive tennis, cycling on hills, digging in the garden, fast dancing, heavy housework, heavy yard work, jogging quickly, running, scrubbing the floors and washing the windows.Findings of StudyOverall, the participants of the study spent an average of 5.9 hours each day taking part in non-vigorous activities, and an average of 1.2 hours doing vigorous activities. By the end of 11 years, 1,506 of the women had been diagnosed with breast cancer.The study found that the women who were the most active had a 13% lower risk of getting post-menopausal breast cancer, when compared with their least active counterparts.A significant finding is that this difference was a lot more pronounced in women in the normal weight range (body mass index below 25). For this group, the difference in risk between the most active and least active women was 30%.On the other hand, for women who were overweight or obese, there was no difference in risk between the most active and least active women."The association with physical activity was essentially limited to the leaner women," said Dr Michael Leitzmann, leader of the study.The ImplicationsOne limitation of the study was that it only measured the level of physical activity once, which would not have given a very accurate reflection of the women's level of physical activity over the whole period of the study. Even then, the study team still felt that physical activity in mid to late adulthood had an important influence on the risk of breast cancer.And, from the findings of the study, we can probably draw two conclusions. Firstly, even for women who are in the normal weight range, a sedentary lifestyle is still a risk factor for breast cancer. Further, for overweight women, being physically more active did not seem to help.The bottomline? If you are serious about averting breast cancer, you may want to watch your weight, and make sure you are getting enough vigorous exercise.Main SourceIntense activity curbs breast cancer risk (</span></strong></em><a href="http://www.canada.com/calgaryherald/news/story.html?id=c4e29bc0-f117-4dbb-9f41-eaa9b2902708" target="_blank"><em><strong><span style="font-size:130%;color:#cc66cc;">http://www.canada.com/calgaryherald...</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc66cc;">)</span></strong></em>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-73697224310232248672009-01-28T06:55:00.000-08:002009-01-28T06:58:34.204-08:00Conventional Prostate Cancer Treatment Contributes to Cognitive Decline<em><strong><span style="font-size:130%;color:#339999;">Through many cancer regiments, the results of the treatments leave the patients with debilitating and most of time deadly side effects such as hair loss, vomiting, weight loss, edema, immune dysfunction, etc. For prostate cancer, another consequence of the treatment can be added to the list: the degeneration of cognitive abilities.Typically, prostate cancer patients go through a treatment known as androgen deprivation therapy (ADT) or hormone deprivation therapy that blocks testosterone production and can slow the growth of the tumor.Though a recent MSNBC article presents the type of cognitive decline as miniscule and limited to functions such as spatial ability and the ability to multitask (and other such actions), can we be certain that the effects of this treatment are as minimal as the mainstrem media make it out to be? I do not think anyone can accurately know the answer to that question, unless there are those who know these effects to be more serious than what is reported here; however, what is sure is that these cognitive decline effects can certainly be avoided through natural means.One way to treat prostate cancer is to cut out low-fat dairy products. Low-fat dairy products are callously promoted under the misconception that saturated fat is unhealthy and "bad" for you. A study conducted by the Cancer Research Center of Honolulu last year found that, after collecting data from 1993-2002 of 82,483 male participants forty-five years old and over, there was a twelve percent decrease in the risk of developing prostate cancer for the whole milk drinkers: there was a sixteen percent increased chance for developing the illness for those who drank 2% milk or skim milk.Another way to treat prostate cancer is to increase the intake of broccoli and tomatoes together. Sheryl Waters of Natural News wrote, when quoting Professor John Erdman of University of Illinois food science and human nutrition, that, "When tomatoes and broccoli are eaten together, we see an additive effect. We think it's because different bioactive compounds in each food work on different anti-cancer pathways," These documented effects demonstrate the wonderful, yet simple, solution to better health that broccoli and tomatoes provide.Unfortunately, there is another added side effect to the purported treatment for prostate cancer; however, that does not have to be the undue fate of the illness's sufferers. There are natural treatments that can help to restore the physical and mental health of the afflicted.Sources:1.

Yet evidence increasingly suggests that milk is not as healthy as it has been believed to be. Health concious people are giving up milk and turning to alternatives. Here are 7 reasons why all of us can consider avoiding cow's milk:1) Milk doesn't keep our bones healthy, preventing fractures and osteoporosis. In fact, according the Nurse's Health Study, dairy may actually increase the risk of fractures rather than protecting our bones. Countries such as those in Africa and Asia who don't consume large amounts of dairy actually have the lowest rates of osteoporosis.2) Milk is not the great source of calcium that most people believe it is. First of all, pasteurizing milk kills all of the nutrients, including calcium. Second, spinach, tahini, kale and other green leafy vegetables are the best sources of calcium on the planet.3) Milk is has been linked with acne by at least three large-scale studies reported in the American Journal of Dermatology. Research shows that there is up to 44% more chance of developing acne in those who drink milk.4) Dairy may raise cancer risk. Research has revealed that a higher intake of dairy products may increase a man's risk of prostate cancer by 30 to 50 percent. In addition, the body's insulin-like growth factor-1 (IGF-1), which is a known cancer promoter is increased by drinking milk.5) Approximately 75 percent of the world's population is lactose intolerant, which means that they are unable to fully digest dairy. Lactase is the enzyme needed to digest lactose, and most people stop producing it around the age of 5.6) Dairy is full of saturated fat and is linked to heart disease. Like cancer, countries such as Japan have a very low level of heart disease, and research commissioned by the New Zealand company A2 shows that there could be a link between a protein in milk.7) People with many different healthy complaints notice a significant improvement when they avoid dairy. Health complaints associated with dairy intolerance include irritable bowel syndrome, allergies, sinus problems, and ear infections.So what is the first step in giving up milk?*Get loads of sunshine to ensure plenty of vitamin D.*Start eating masses of green leafy vegetables so you can ensure you are getting your calcium.*Try substituting milk with nut milk.*Many studies show that raw milk (unpasteurized) is far better because the nutrients have not been destroyed. Raw goat's milk and raw sheep's milk are both increasingly popular.*Avocado is a wonderful butter substitute. It offers a creaminess that is people who have given up milk miss. Many vegans and raw foodists find that avocado is one of the most essential transition foods.*Coconut butter is another buttery, creamy substitute for those that want to give up milk. Coconut butter is the healthiest oil in cooking. It can also replace butter as a spread and cream in healthy cakes and desserts.</strong></span><a href="http://www.womenrepublic.co.uk/" target="_blank"><span style="font-size:130%;color:#cc33cc;"><strong>http://www.womenrepublic.co.uk</strong></span></a><a href="http://www.mercola.com/" target="_blank"><span style="font-size:130%;color:#cc33cc;"><strong>www.mercola.com</strong></span></a>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-31145478244483314152008-12-31T15:25:00.000-08:002008-12-31T15:27:08.828-08:00Common food additive may increase lung cancer risk<em><strong><span style="font-size:130%;color:#cc33cc;">A diet high in inorganic phosphates, which are found in a variety of processed foods-including meats, cheeses, beverages, and bakery products-can increase the risk and spread of lung cancer, according to a new study.<br />Washington, Dec 30 : A diet high in inorganic phosphates, which are found in a variety of processed foods-including meats, cheeses, beverages, and bakery products-can increase the risk and spread of </span></strong></em><a href="http://www.andhranews.net/Features/Health/Lung-Cancer.asp"><em><strong><span style="font-size:130%;color:#cc33cc;">lung cancer</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc33cc;">, according to a new study.<br />The study, using a mouse model, indicated that inorganic phosphates might speed growth of </span></strong></em><a href="http://www.andhranews.net/Features/Health/Lung-Cancer.asp"><em><strong><span style="font-size:130%;color:#cc33cc;">lung cancer</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc33cc;"> tumours, and even contribute to the development of those tumours in individuals predisposed to the disease.<br />Conducted by Myung-Haing Cho, D.V.M., Ph.D., and his colleagues at Seoul National University, the study also suggested that dietary regulation of inorganic phosphates might play an important role in </span></strong></em><a href="http://www.andhranews.net/Features/Health/Lung-Cancer.asp"><em><strong><span style="font-size:130%;color:#cc33cc;">lung cancer</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc33cc;"> treatment.<br />"Our study indicates that increased intake of inorganic phosphates strongly stimulates </span></strong></em><a href="http://www.andhranews.net/Features/Health/Lung-Cancer.asp"><em><strong><span style="font-size:130%;color:#cc33cc;">lung cancer</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc33cc;"> development in mice, and suggests that dietary regulation of inorganic phosphates may be critical for </span></strong></em><a href="http://www.andhranews.net/Features/Health/Lung-Cancer.asp"><em><strong><span style="font-size:130%;color:#cc33cc;">lung cancer</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc33cc;"> treatment as well as prevention," said Cho.<br />The study revealed that high levels of inorganic phosphates can stimulate non-small cell </span></strong></em><a href="http://www.andhranews.net/Features/Health/Lung-Cancer.asp"><em><strong><span style="font-size:130%;color:#cc33cc;">lung cancer</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc33cc;"> (NSCLC) pathways.<br />"</span></strong></em><a href="http://www.andhranews.net/Features/Health/Lung-Cancer.asp"><em><strong><span style="font-size:130%;color:#cc33cc;">Lung cancer</span></strong></em></a><em><strong><span style="font-size:130%;color:#cc33cc;"> is a disease of uncontrolled cell proliferation in lung tissue, and disruption of signaling pathways in those tissues can confer a normal cell with malignant properties.

In Japan, when age-standardized to the world population, the incidence rate was 28.3 per 100,000 in 1991, and rose to 39.5 in 2001.In the United States in 2004, the disease hit more than 185,000 women and over 1,800 men, with almost 41,000 women and 362 men dying from it that year. In that year, after non-melanoma skin cancer, breast cancer was the next highest cancer killer of American women. It was also their fifth highest killer overall.Next up, over to Canada, where, among the women, breast cancer is the most common type of cancer to strike. According to Canadian Cancer Society estimates, about 22,400 women will be diagnosed with the disease this year, with about 5,300 dying from it.With such grim statistics, every little thing which can be done to prevent and combat the disease becomes all the more critical.Details of StudyThe Ohsaki National Health Insurance (NHI) Cohort Study started in 1994 and involved 28,515 women in northeastern Japan. The questionnaire used included information on sleep duration and other lifestyle habits.Participants who had withdrawn from the NHI study before follow-up, had a history of cancer, did not provide information on their sleep duration, and who reported having slept for less than 4 hours or more than 12 hours every night were omitted. This left the data for 23,995 women to be analyzed. An 8-year period, from 1995 to 2003, was used, during which 143 women were hit with breast cancer.Findings of StudyThe women who slept 7 hours each night was used as the reference group. It was then found that women who slept 6 hours or less each night had a 62% higher risk of getting breast cancer. On the other hand, those who slept 9 hours or more every night had a 28% lower risk of getting the disease.It would follow, then, that those who slept 6 hours or less every night had 2.25 times the risk of getting breast cancer when compared to those who slept 9 hours or more each night.The results remained largely consistent even when participants who were diagnosed with breast cancer within 3 years from the start of the study were excluded, or when the data was analyzed by age and menopausal status.Previous StudiesThe findings of this study validates the findings of two previous prospective cohort studies relating breast cancer and sleep duration (Verkasalo et al, 2005, Wu et al, 2008). Those two studies had also shown a significant decrease in breast cancer risk for those who slept the longest.It must be noted, though, that another such study (Pinheiro et al, 2006) did not find any such association. The study team pointed out, however, that that study had looked at residential nurses, who underwent rotating-shift work and had varying sleep timings. The findings of that study thus might not be applicable to the general population.Strengths and Limitations of StudyAccording to the study team, their research had a couple of strong points. Firstly, it used study subjects from the general population, thus allowing for overall generalization of its findings. In addition, it used the Miyagi Prefectural Cancer Registry, which the study team said is “one of the earliest and most accurate population-based cancer registries in Japan”.There were also, however, several limitations. Firstly, self-reported sleep data was used, and assessment was also only carried out once. In addition, and probably very significantly, no information on sleep quality, sleep timing, use of sleep medication, or presence of sleep disorders were available. These factors, of course, are very important as they can directly or indirectly affect cancer risk.Further, the researchers added that they had no information with regard to rotating-shift work or night work, but they felt that would not have affected their findings greatly as more than half of the study subjects were housewives, farmers or retired.The Sleep Duration – Breast Cancer LinkWhy is breast cancer risk linked to sleep duration? The answer could lie in melatonin, which is secreted during night sleep. When a person sleeps fewer hours, less melatonin is secreted, and lower levels of the chemical had previously been associated with increased breast cancer risk.In addition, melatonin may possess an inhibitory effect on gonadal function, which includes synthetizing and secreting sex hormones. It had also been found to have an antiproliferative effect on breast cancer cells.The Bottom LineIf the findings from this study are indeed accurate, then there is an immense difference in breast cancer risk between sleeping 4 to 6 hours every night, and just sleeping 1 to 3 hours more each night. In fact, it is more than likely that the protective effects of sufficient sleep also extend to other forms of cancer. 7 hours of sleep a night may thus be a good number to aim for.Hopefully, in time to come, further research will reveal more information relating sleep and disease risk, with sleep quality and sleep timing being two of the main possibilities.Main SourceSleep duration and the risk of breast cancer: the Ohsaki Cohort Study (</em></strong></span><a href="http://www.nature.com/bjc/journal/v99/n9/full/6604684a.html" target="_blank"><span style="font-size:130%;color:#00cccc;"><strong><em>http://www.nature.com/bjc/journal/v99/n...</em></strong></span></a><span style="font-size:130%;color:#00cccc;"><strong><em>)</em></strong></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-88115503984126103532008-12-30T10:18:00.000-08:002008-12-30T10:19:05.222-08:00Talcum powder as dangerous as asbestos<span style="font-size:130%;color:#cc33cc;"><em><strong>Back in 1973 the evidence about the dangers of talc prompted the FDA to think about steps to reduce the level of the asbestos-like fibers in cosmetic talc. The dangers are that talc is related to asbestos – a known carcinogen – and that the presence of talc particles is linked to tumors. However, the FDA did not regulate cosmetic talc even after 1993 when the National Toxicology Program reported that cosmetic talc, which had no fibers, was the cause of tumors in animals.Talc is a soft green-gray colored mineral produced from rocks and processed into a powder. Pure talc mineral is a hydrous magnesium silicate. Some trace minerals are removed in processing but very small fibers remain which are similar to those that occur in asbestos.Most talc is formed from altered dolomite or magnesite when there is excess dissolved silica. A number of minerals associated with talc include: tremolite, serpentine, anthophyllite, magnesite, mica and chlorite. Note that there are six minerals are defined as asbestos and two of these are also talc – tremolite and anthophyllite.Commercial talc may contain impurities and contaminates such as asbestos and crystalline silica. In fact asbestos may occur in talc.Talc is used in diverse industries and for a wide variety of purposes. It is commonly used in cosmetics and body powders, including those for babies. It has hydrophobic surface properties helping to keep skin dry.In the paper industry, talc is used as a filler which enhances the quality of the paper for printing and appearance of opacity. It is used in ceramic tiles, and in paints and coatings. Did you know that the dust on some chewing gums contains talc? Talc is also used in in flea and tick powder, deodorants, chalk and crayons, textiles and soap.Now we have another study (published in the Cancer Epidemiology, Biomarkers and Prevention journal) that shows that women who use talcum powder around their genital areas are 40% more likely to develop ovarian cancer. The study led by Dr Maggie Gates of Harvard Medical School analyzed 3,000 women. The risk of ovarian cancer for those who used talcum powder once a week was found to be 36%, while those using it every day the risk went up to 41%.In a recent separate incident a group of doctors at the Harvard Medical School found talc particles in the pelvis of a woman diagnosed with ovarian cancer. She had used talcum powder every day for around 30 years.In 1982 in Cancer magazine the conclusions from a study recommend that the lifetime use of talcum powder increases the risk of ovarian cancer by more than three times. Consequently, various cancer organizations warn against the use of talcum powder. For many people this warning is a bit late.Talc also causes poisoning due to accidental exposure. The website preventcancer.com (see link below) state that from the early 1980’s accidental inhalation of talc (baby powder) has caused the death or serious illness of several thousands infants.Talc is used in some medications such as some antiacids and in some antiseptics. So the question is is talc dangerous when used as medications? Actually there are so many questions we need to ask. What guidelines should be available and what regulations exist that protect people? Why do so many children suffer needlessly because of lack of care demonstrated by authorities? Why weren’t women protected against the use of talcum powder 30 years ago?Over and over again when there is a choice about caring for our fellow human beings and about earning profits, selfishness wins. And the authorities lack the care and the compassion required to serve us well.Reference: </strong></em></span><a href="http://www.preventcancer.com/consumers/cosmetics/talc.htm" target="_blank"><span style="font-size:130%;color:#cc33cc;"><em><strong>www.preventcancer.com/consumers/cosmeti...</strong></em></span></a>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com1tag:blogger.com,1999:blog-816395898133055568.post-86954125510080193412008-12-30T10:14:00.000-08:002008-12-30T10:17:12.880-08:00Selenium Curbs AIDS Virus, may Fight Cancer<span style="font-size:130%;color:#339999;"><em><strong>After decades of attempting to fight AIDS with experimental vaccines and drugs, scientists have recently discovered how several natural substances could be powerful weapons against the disease. For example, in mid-November, UCLA AIDS researchers published research concluding that the herb astragalus contains a substance with the potential to possibly replace the side-effect plagued HAART (highly active antiretroviral therapy) currently used to treat AIDS patients. </strong></em></span><a href="http://www.naturalnews.com/024799.html" target="_blank"><span style="font-size:130%;color:#339999;"><em><strong>http://www.naturalnews.com/024799.html</strong></em></span></a><span style="font-size:130%;color:#339999;"><em><strong>Now Penn State immunologists say they’ve documented how a micronutrient could help battle AIDS. Their findings, just published in the Journal of Biological Chemistry, show how selenium could dramatically put the brakes on the replication of HIV, the virus that causes AIDS.Selenium is needed by the body to maintain normal metabolism. It’s also increasingly being studied for its anti-cancer properties. Although other nutrients usually bind to proteins, selenium actually becomes incorporated into proteins, forming what are called selenoproteins. These selenium-containing proteins are believed to slow the spread of infections. However, when HIV infects a person, the virus manages to degrade selenoproteins, probably due to a protein, dubbed Tat, produced by the HIV virus. In particular, Tat seems to target a selenoprotein known as TR1.But there may be a way to get around this degradation of selenoproteins -- supplementation with selenium. "Since HIV targets the selenoproteins, we thought that the logical way to deal with the virus is to increase the expression of such proteins in the body," K. Sandeep Prabhu, assistant professor of immunology and molecular toxicology at Penn State, said in a statement to the press.To test their idea, the scientists isolated blood cells from human volunteers who did not have HIV. Then they infected those cells with the virus and added a form of selenium called sodium selenite to the cell culture.The result? The added selenium inhibited the replication of HIV at least 10-fold, in comparison to cell cultures with no added selenium. The scientists also selectively reduced the production pf the selenoprotein TRI. When there was less selenium-containing protein,HIV replication soared 3.5 times. Bottom line: The research confirms that an increase in selenium in cells zaps replication of HIV while a reduction in the amount of selenium-containing TR1 protein gives the virus a boost."We have found that increasing the expression of proteins that contain selenium negatively affects the replication of HIV. Once we fully understand the function of these selenium proteins, it will give us a handle to come up with more effective drugs," said Dr. Prabhu in the prepared statement for the media.Two more new studies offer additional evidence that selenium may impact the immune system. German scientists from St. Josefs-Hospital in Wiesbaden recently published a study in the Swedish medical journal Acta Oncologica that suggests the micronutrient could help prevent prostate cancer and prostate enlargement. The researchers found that whole blood selenium levels were significantly lower in all men tested who had prostate cancer or benign prostate hypertrophy (which can cause difficulty with urination) and concluded, “our findings may support the recommendation of selenium supplementation” to help prostate health. What’s more, a study just published in the journal Molecular Nutrition and Food Research suggests enzymes that contain selenium have anti-oxidative and anti-inflammatory effects that could make them important in preventing prostate and colorectal cancers.Too much selenium in can cause a condition called selenosis, resulting in loss of hair, nail problems, nausea, irritability, fatigue, and mild nerve damage. However, selenium toxicity is extremely rare. A lack of selenium may, in fact, be far more common and potentially more dangerous to health. According to the National Institutes of Health, people age 14 and older should take in about 44 micrograms of selenium a day. Good sources of the micronutrient include Brazil nuts, eggs, brown rice, whole wheat bread and pasta, walnuts and oatmeal.</strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-38170268424990979902008-12-30T10:09:00.000-08:002008-12-30T10:13:53.380-08:00Cancer Doc Issues Warning About Cell Phone Use<span style="font-size:130%;color:#cc33cc;"><em><strong>The director of the University of Pittsburgh Cancer Institutes and the Cancer Centers at the University of Pittsburgh Medical Center has issued a warning to all 3,000 faculty and staff under his supervision, warning them to limit cellular phone use in order to avoid adverse health effects."Recently I have become aware of the growing body of literature linking long-term cell phone use to possible adverse health effects including cancer," the memo from Dr. Ronald Herberman reads.

Consider this unappetizing truth: When you gulp down a nice juicy steak or hamburger, you are contributing to tumor-fueling inflammation in your body.In fact, eating a diet rich in red meat has long been linked to a host of ills including an increased risk of several types of cancer. But what is it about meat consumption that could impact cancer growth? Now scientists at the University of California, San Diego School of Medicine, have found a mechanism that explains how eating red meat, as well as milk, could spur the growth of malignancies. The new study, headed by Ajit Varki, M.D., suggests that inflammation resulting from a molecule introduced through eating these foods could make cancer grow. The research is set for upcoming publication in the Proceedings of the National Academy of Sciences (PNAS).Dr.Varki, UC San Diego School of Medicine distinguished professor of medicine and cellular and molecular medicine and co-director of the UCSD Glycobiology Research and Training Center, and his research team studied a non-human glycan, or sugar molecule, known as N-glycolylneuraminic acid (Neu5Gc). Although this molecule is not produced naturally in the human body, it’s incorporated into human tissues if you eat red meat. The body then develops antibodies against Neu5Gc – and this immune response could potentially trigger a low-grade chronic inflammation, spurring the growth of cancer. In a statement prepared for the media, Dr. Varki explained it has been recognized by scientists for some time that chronic inflammation can stimulate cancer progression."We've shown that tumor tissues contain much more Neu5Gc than is usually found in normal human tissues. We therefore surmised that Neu5Gc must somehow benefit tumors,” Dr. Varki said in the press statement. So the scientists came up with this hypothesis: The fact that Neu5Gc accumulates in human tumors despite circulating anti-Neu5Gc antibodies suggests a low-grade, chronic inflammation has developed, and caused the tumor to grow. To test this idea, the researchers worked with specially bred mice. The animals lacked the Neu5Gc molecule , just as humans do before they eat red meat and the molecule is absorbed into their bodies, and they had tumors.Anti-Neu5Gc antibodies were given to half of the mice . In those animals, the antibodies induced inflammation and their cancers started growing faster. In the control group comprised of mice that were not treated with antibodies, their tumor growth was far less aggressive.Building on previous research that has shown that humans who take non-steroidal anti-inflammatory drugs (commonly known as NSAIDs) have a reduced risk of cancer, the researchers tried giving NSAIDs to the mice with cancerous tumors fueled by anti-Neu5Gc antibodies. The result? The anti-inflammatory treatment blocked the effect of the Neu5Gc antibodies and the tumors became smaller."Taken together, our data indicate that chronic inflammation results from interaction of Neu5Gc accumulated in our bodies from eating red meat with the antibodies that circulate as an immune response to this non-human molecule – and this may contribute to cancer risk," Varki said in the media statement.For anyone interested in reducing inflammation through natural, non-drug methods, here are seven top strategies to incorporate into your lifestyle:1. Stop eating meat and dairy products.2. Concentrate on a Mediterranean flavored style of eating with lots of fruits, vegetables, whole grains , olive oils and nuts. Research has shown these foods lower inflammation levels.3. Don’t smoke and avoid those who do – second hand smoke can contribute to inflammation.4. Know your oils. Avoid all inflammation-causing trans-fats, hydrogenated and partially hydrogenated oils as well as saturated animal fats. Instead, add inflammation-fighting omega-3 oils like flaxseed, canola and walnut oil to your diet.5. Lose weight if you need to. Research has shown that a waist that measures over 40 inches in a man or over 35 inches in a woman is a sign of probable high inflammation.6. Don’t skimp on sleep. Previous studies have concluded less than six hours of sleep can result in inflammation .7. De-stress. Try yoga, meditation, walking and other forms of exercise. Staying continually stressed out means your body is releasing excess, inflammation-promoting stress hormones . Schedule a minimum of 20 minutes a day to let your worries go.</strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-79666298130219910892008-12-30T10:03:00.000-08:002008-12-30T10:05:27.637-08:00Fruits and Vegetables Regulate the Cell Cycle to Prevent Cancer<span style="font-size:130%;color:#cc33cc;"><em><strong>It’s amazing that more than 2000 years ago we realized many universal truths, and we did it without the scientific method. One person who really knew what he was talking about was Hippocrates, who said “Let food be thy medicine and medicine be thy food”.We lost our common sense for awhile and fell in love with a disease establishment that claimed science was on its side. Apparently we are now coming to earth again in a new age where science and sense meet. Scientists are now explaining the finer points of the truth Hippocrates was trying to tell us -- nature has provided us with all the tools we need to stay healthy. An example of this type of research is a study published in the January, 2008 edition of Frontiers in Bioscience that deals with the importance of regulation of the cell cycle in prevention of cancer.What is the cell cycle?The growth and maintenance of plants, animals and humans is the result of an ordered series of events which constitute the cell cycle. During this cycle, chromosomes are duplicated and one copy of each duplicated chromosome is transferred from the mother cell to the daughter cell. Proper regulation of this cycle is essential for the normal development of multi-cellular organisms. If control of this cycle is lost for any reason, cancer or other degenerative diseases may be the result.Successful cell replication depends on two critical processes: the replication of DNA, and mitosis -- the nuclear division of the daughter cell from the mother cell. The master controllers of these processes are protein kinases that regulate the proteins involved in this DNA replication and mitosis.The researchFor this study, scientists reviewed the sequence of events that regulate cell cycle progression with an eye towards the check points and mechanisms that cells employ to insure DNA stability during this cell cycle even in the face of genotoxic stress.They noted that key transitions in the cell cycle are regulated by the activities of the various protein kinase complexes composed of cyclin and cyclin-dependent kinase (CDK) molecules. These cyclins are CDK binding partners which are required for kinase activity and are intimately linked to the cell cycle stage. CDK activity can be controlled by other mechanisms, such as the addition of a phosphate group, resulting in deregulation of the cell cycle. This is the process that leads to cancer.Although diets rich in fruits and vegetables are increasingly being recommended for the prevention of cancer, their active ingredients and mechanisms of action have not been well understood. This research presents evidence that dietary agents identified from fruits and vegetables can act to modulate the effects of deregulated cell cycle checkpoints. It is through this mechanism that cancer may be prevented by dietary choice.Compounds from fruits and vegetables that appeared particularly noteworthy were apigenin (celery, parsley), curcumin (turmeric), epigallocatechin-3-gallate (green tea), resveratrol (red grapes, peanuts and berries), genistein (soybeans), and silymarin (milk thistle). </strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-30510644010697535342008-12-30T10:00:00.000-08:002008-12-30T10:01:30.909-08:00How to Protect Yourself From Cancer-Causing Acrylamides in the Foods You Love<em><strong><span style="font-size:130%;color:#339999;">Can you eat the foods you love occasionally without compromising your health? A new study shows that adding certain compounds to your diet can protect you from the harmful effects of acrylamides found in many of American’s favorite foods.Acrylamides are cancer causing agents created when foods are grilled, fried, baked or roasted. They are a byproduct of cooking starchy foods at high temperatures. Acrylamides are found in the highest levels in foods that become browned in the cooking process such as french fries, potato chips, and grilled meats and vegetables that have grill marks on them. Toasted bread and cereals, and baked foods such as sweet potatoes and browned meats also contain substantial amounts, as does dried fruit.The danger of acrylamides was first revealed in 2002, when researchers found that women who consumed 40 micrograms or more of acrylamides each day had twice the risk of endometrial and ovarian cancer risk of women who ate substantially smaller amounts. This would be the amount of acrylamides contained in a small portion of potatoe chips. The FDA has been slow to acknowledge the threat of acrylamides. Food manufacturers have not been required to publish data on the levels of acrylamides in their products.Research reveals the way for consumers to protect themselvesAs published in the July 15, 2008 edition of the Journal of Agriculture and Food Chemistry, researchers found that three dietary constituents, tea polyphenols, resveratrol, and diallyl trisulfide, inhibit damage to DNA from acrylamides at levels typically found in human exposure. Results of analysis of the compounds with accelerator mass spectrometry demonstrated that all three significantly inhibited the formation of acrylamide damage to liver DNA, whereas tea polyphenols and diallyl trisulfide reduced DNA damage to protamines and hemoglobin as well.Further biochemical studies showed that acrylamides could significantly inactivate creatine kinase and glutathione S-transferase and deplete glutathione. When the inhibitors were treated with acrylamide, all of them could effectively recover the activities of creatine kinase. In addition, tea polyphenols and diallyl trisulfide could increase glutathione S-transferase at a remarkably high level. Creatine kinase is an enzyme essential in biochemical reactions and energy generation. Glutathione S-transferase is a family of enzymes that play key roles in the detoxification of substances such as carcinogens, drugs, and byproducts of oxidative stress.Acrylamides are formed when carbohydrate containing foods are baked, fried or roasted. They have been shown to cause cancer in animals exposed to high doses, as well as nerve damage. Acrylamides are not added to foods but occur naturally in the cooking process. Because of this, information on them is not required on food labels.Any starchy food cooked at high temperatures will contain acrylamides. Potatoes that are fried may be the worst offenders, with potato chips fried to a golden brown containing the highest levels. Boiled or mashed potatoes will contain acrylamides as will cooked sweet potatoes. It can also be found in toasted or roasted cereal grains and bread products -- again with the highest levels contained in those baked to a golden brown, and corn roasted on a grill, or popped in oil. Pretzels are promoted as healthy snacks, but that golden brown color is your tip that they contain high levels of acrylamides. Coffee creates acrylamides during its roasting.Acrylamides were discovered by Swedish scientists in 2002, and made headlines across America when they were first reported. Since then, there has been little interest by the FDA to keep people abreast of the dangers of eating acrylamide containing foods. The method by which acrylamides form in food remains unknown.What we do know from this study is that by taking steps to protect ourselves from acrylamides, we don’t have to be boorish sticks when we go out with our friends. We can eat foods containing acrylamides without suffering their effects if we also make sure we are fortified with tea polyphenols, resveratrol and diallyl trisulfide.Numerous studies have demonstrated the anti-cancer properties of tea polyphenols, with recent studies adding gastric, esophageal and skin cancers to the list of those inhibited by polyphenols from tea consumed in high amounts. Another study showed ovarian cancer risk reduced by 46 percent in women drinking 2 cups of tea daily. Researchers have found tea polyphenols to lower cholesterol levels, prevent blood clots, and help prevent heart disease. All types of tea contain polyphenols, with green and white tea having the highest levels due to their minimal processing.Resveratrol is turning out to be so good for us that red wine may end up on the superfood list. It is found in the skin of red or purple grapes, and in peanut products that contain the skins, such as Spanish peanuts. Resveratrol has also been shown to help prevent cardiovascular disease and cancer. A glass of tea or red wine during a meal containing foods that have produced acrylamides will offer you protection.Diallyl trisulfide is a compound found in garlic that has been roasted, smashed or otherwise processed. Shown particularly effective in the prevention and treatment of prostate cancer, this compound is also a potent immune system booster.All three of these compounds are extremely effective antioxidants.If you plan to be eating foods that contain acrylamides, you can protect yourself by having supplements of theses compounds on hand. Each offers an array of other health benefits.</span></strong></em>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-322149191283963532008-12-30T09:55:00.000-08:002008-12-30T09:59:53.483-08:00Study Shows Link Between Diet and Stress Induced Cancer<span style="font-size:130%;color:#339999;"><em><strong>Will the stress in your life cause you to develop cancer? The answer to this question may depend on what you eat according to a study published in the August, 2008 edition of the International Journal of Oncology.Researchers examined the possible growth promoting effects of the stress-associated hormone norepinephrine on immortalized human pancreatic duct epithelial cells. The results suggested that norepinephrine can increase proliferation of these cells. They then evaluated the ability of norepinephrine to induce interleukin-6, and vascular endothelial growth factor, both believed to promote cancer of pancreatic duct epithelial cells. They found that norepinephrine can indeed increase the interleukin-6 and vascular endothelial growth factor in the cells.Based on theses results, the researchers performed further testing to see if dietary agents sulforaphane and resveratrol can inhibit norepinephrine-mediated increases in cell proliferation. Results indicated that sulforaphane but not resveratrol inhibits the norepinephrine-mediated increases in cell proliferation. Sulforaphane also inhibited norepinephrine-mediated increase of the interleukin-6 levels of the cells.We are living through an extremely stressful period of history. Hundreds of studies have documented how stress impacts our immune systems and ability to fight off invading organisms. This study goes a long way toward documenting the link between stress and cancer. The implications for further research are huge.Inhibiting norepinephrine is no small feat. Norepinephrine is a neurotransmitter that is similar to adrenaline. These hormones act together to produce heart rate and blood pressure increases among other biochemical actions to launch us into our natural defense mode, described as fight or flight. Chronic high levels of stress result in chronic high levels of norepinephrine and adrenaline.Sulforaphane is a compound that can be obtained by eating cruciferous vegetables such as Brussels sprouts, broccoli, cabbage, cauliflower, bok choy, kale, collards, kohlrabi, mustard, turnip, radish, rocket, and watercress.The compound’s anticancer activity is thought to be related to the induction of phase-II enzymes such as quinone reductase and glutathione S-transferase, and the enhanced transcription of tumor suppressor proteins.Sulforaphane is particularly abundant in broccoli sprouts. Researchers at Johns Hopkins University School of Medicine have been dedicated in their efforts to provide us with a broccoli sprout that guarantees a consistent level of sulforaphane. According to Johns Hopkins, eating just one ounce of their broccoli sprouts provides as much sulforaphane as more than a pound of cooked broccoli. Their product, called Brocco Sprouts, is available at many traditional supermarkets.If eating healthy amounts of cruciferous vegetables does not appeal to you, try adding broccoli sprouts to a sandwich or salad. Broccoli sprouts don’t have to be eaten daily to provide their full effect. A one ounce serving is good for three days worth of full spectrum antioxidant protection from sulforaphane comparable to the best antioxidant supplements on the market. A box of sprouts contains four of these servings and retails for about 4 dollars.Juicing is another good way to consume cruciferous vegetables, particularly if you have digestive difficulties. You can add cruciferous vegetables to your vegetable juice recipes. One large stalk of broccoli makes only about an inch of power packed juice in a glass, so it doesn’t have a huge impact on the taste of the recipe.Supplements of broccoli sprouts are available at health food stores and online health retailers such as Vitacost or Lucky Vitamin. The best known is called Broccoliv. Vitacost has a less costly house brand.</strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-399525169014279042008-12-30T09:49:00.000-08:002008-12-30T09:52:54.706-08:00Smoking Linked to Bladder Cancer<span style="font-size:130%;color:#cc33cc;"><em><strong>Smoking strongly increases a person's risk of developing bladder cancer - a risk that the majority of the population seems to be unaware of, according to a new analysis conducted by researchers from the University of Michigan Comprehensive Cancer Center."The general public understands that cigarette smoking can lead to lung cancer, but very few people understand that it also can lead to bladder cancer," study co-author James E.

For example, one study found that a person's risk of developing bladder cancer goes down by 40 percent within the first four years of quitting smoking.Yet the general population remains unaware of this connection, the researchers also found, as are patients who have been diagnosed with bladder cancer. Only 22 percent of bladder cancer patients surveyed knew that smoking increases the risk of developing the </strong></em></span><a href="http://www.naturalnews.com/disease.html"><span style="font-size:130%;color:#cc33cc;"><em><strong>disease</strong></em></span></a><span style="font-size:130%;color:#cc33cc;"><em><strong>."A big gap exists between patient knowledge and their actual risk," co-author Seth A.

In the United States, it is the fourth most common cancer in men in the ninth most common in women, with more than 47,000 new cases diagnosed in men and 16,000 in women each year. The higher prevalence in men is believed to be due to the fact that male sex hormones play a role in the development of the disease.Other than smoking, risk factors include being African-American or Hispanic and having a family history of the cancer. Exposure to secondhand smoke is also a suspected risk factor.</strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0tag:blogger.com,1999:blog-816395898133055568.post-32255793482537755452008-12-30T04:16:00.000-08:002008-12-30T04:18:13.628-08:00Saw Palmetto Keeps Prostates Healthy and Helps Prevent Baldness<span style="font-size:130%;color:#cc33cc;"><em><strong>Saw palmetto may be a man’s best friend. It's the primary herb helping men maintain prostate health that’s very popular throughout Europe for its ability to relieve symptoms associated with benign prostatic hyperplasia (BPH), otherwise known as enlargement of the prostate. In the U.S. where pharmaceuticals are the standard of care for prostate problems, saw palmetto is gaining popularity following several recent studies showing it provides relief from short-term urinary symptoms and other symptoms of BPH, as well as relief from inflammation of the prostate and cell proliferation. It also promotes hair growth in men with thinning hair or baldness. It provides these benefits safely, naturally and with no noted side effects.Saw palmetto, botanically known as Serenoa repens or as sabal palm in Europe, is a magnificent palm tree that grows naturally in Florida, Georgia and Mississippi. The therapeutic compound comes from the berries of the plant. Historical use of the herb can be traced in the Americas to the Mayans who used it as a tonic and to the Seminoles who took it as an expectorant and antiseptic.Saw Palmetto prevents conversion of testosterone to DHTThe herb possesses several mechanisms of action, with the primary action relating to prostate health being its ability to inhibit the 5-alpha reductase enzyme which converts testosterone, the male sex hormone, to a more potent metabolite, dihydrotestosterone (DHT). In addition, it blocks receptor sites on cell membranes required for cells to absorb DHT. An excess of DHT is believed one of the primary causes of prostate problems as well as the cause of male baldness.Recent research documents the health benefits of saw palmettoIn a study reported in the Journal of Urology, men with BPH obtained significant short-term symptom relief with saw palmetto. Ninety-two men between the ages of 49 and 75 with lower urinary tract symptoms were divided into two groups, one treated with two soft gels of saw palmetto, and the other treated with a placebo. Both groups were treated for a twelve week period. Maximum urinary flow was significantly higher in the treatment group compared to the placebo group, and urinary resistance was significantly lower. Yet mean prostate volume was comparable in the two groups.The American Family Physician journal reported a diagnosic and management review of BHP. They found that through its ability to inhibit 5-alpha reductase, saw palmetto as well as rye grass pollen extract, and pygeum relieved symptoms such as urinary hesitancy, weak stream, nocturia, incontinence, and recurrent urinary tract infections.A review of literature published in Archivio Italiano di Andrologia found that saw palmetto, lycopene and selenium, the three most widely used compounds in treatment of the prostate, have a common feature which may be a dual activity on proliferative disorders as well as on inflammatory conditions at the level of the prostate gland.A study reported in Anticancer Research investigated the effect of an extract of saw palmetto on hormone sensitive and insensitive prostate and breast cancer cells, and urinary bladder, colon and lung cancer cells in order to assess its growth inhibitory abilities. They found that saw palmetto extract induced a dose-dependent anti-proliferative effect on all the human malignant cells tested.Saw Palmetto reduces male pattern hair lossMale hair loss can often be attributed to the conversion of testosterone to DHT promoted by the 5-alpha reductase enzyme. DHT causes hair thinning by shrinking the follicles in the scalp, which results over a period of time in the follicles being far too small for hair to grow, resulting in baldness.The link between DHT and hair loss has been well established, with numerous clinical studies and surveys concluding that this hormone can be directly linked as a cause of as many as 95% of all cases of hair loss. The studies have shown that this condition is genetically linked, with excessive production of DHT being passed from generation to generation. It is this condition that is targeted by pharmaceutical products such as propecia (finasteride), and rogaine (minoxidil).While the testosterone to DHT conversion creates hair loss on the head, it also promotes the growth of hair in places where it is not wanted. By preventing this hormonal conversion, saw palmetto is showing in research to be effective in the treatment of male hair loss. It is able to get the hair off men’s backs and back on their heads. Some studies have shown it to be as effective as Propecia and Rogaine. This aspect of saw palmetto was discovered by people using it for prostate issues who started reporting the regrowth of hair on their heads.Shampoos and lotions containing saw palmetto are available at health food stores and on line. Saw Palmetto is available as a supplement. The dosage amount for men is 300 to 500 mg. per day. Saw palmetto has been shown in research to be non-toxic and safe for extended use.Saw Palmetto is not the only herb able to influence prostate healthSeveral other herbs and plant compounds are potentially useful in maintaining prostate health, including pygeum, nettle, beta sitosterol, and carotenoids such as lycopene. Health of the prostate gland is heavily influenced by the overall health of the body. It’s hard to find a sick prostate gland in a body otherwise possessing excellent health. Following the basics for general health will go along way in promoting prostate health.Pygeum is an African plum tree found in tropical Africa. An extract from the bark of pygeum has been used in Europe as a prevention and treatment of prostate disorders including BPH. More recently in the U.S. pygeum has been marketed along side saw palmetto for prostate health and cancer prevention and treatment.An interesting study reported in Endocrine tested the anti-cancer potential of pygeum in vitro and in vivo. In tissue culture, pygeum extract inhibited the growth of cancerous cells, induced appropriate programmed cell death and altered cell kinetics, down regulated ER-alpha and PKC-alpha protein, and demonstrated the ability to bind with estrogen and androgen receptors. Mice fed with pygeum showed a significant reduction in prostate cancer incidence of 35% compared to controls. Researchers concluded pygeum is a useful supplement for men at high risk of developing prostate cancer.</strong></em></span>لا اسم لي مع عروبتيhttp://www.blogger.com/profile/09098665211213267419noreply@blogger.com0
