Public release date: 13-May-2008 By inducing a specific gene to increase expression of a key enzyme, vitamin D protects healthy prostate cells from the damage and injuries that can lead to cancer, University of Rochester Medical Center researchers report. “Many epidemiological studies have suggested the beneficial properties of vitamin D,” said Yi-Fen Lee, associate professor of urology at the Medical Center who led the research. “Our findings reflect what we see in those studies and demonstrate that vitamin D not only can be used as a therapy for prostate cancer, it can prevent prostate cancer from happening.” The International […]
Chemicals found in green tea may be able to stave off the cognitive deficits that occur with obstructive sleep apnea (OSA), according to a new study published in the second issue for May of the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. Researchers examined the effects green tea polyphenols (GTP), administered through drinking water, on rats who were intermittently deprived of oxygen during 12-hour “night” cycles, mimicking the intermittent hypoxia (IH) that humans with OSA experience. People with OSA have been reported to have increased markers of oxidative stress and exhibit architectural changes in their brain […]
Public release date: 15-May-2008 ORLANDO, FL, MAY 18, 2008—Higher incidences of congenital anomalies, including cryptorchidism (undescended testicles) and hypospadias, were found in boys whose mothers had higher serum levels of certain organochlorine compounds, researchers say. Two separate studies presented today during the Annual Scientific Meeting of the American Urological Association (AUA) in Orlando confirmed existing hypotheses that maternal exposure to endocrine-disrupting chemicals – including total polychlorinated biphenyls (PCBs, such as Arochlor) and organochlorinated pesticides (such as dichlorodiphenyl-trichloroethane, or DDT) may contribute to an increased incidence of these conditions. The data was presented to the media on Sunday, May 18, 2008, […]
Public release date: 15-May-2008 ORLANDO, FL, May 18, 2008—Patients undergoing external-beam radiation therapy (EBRT) for localized prostate cancer may be at an increased risk for secondary malignancy, according to a study from researchers in Canada, Italy and the United States presented today during the Annual Scientific Meeting of the American Urological Association (AUA) in Orlando. Researchers presented data to reporters during a special press conference on May 19, 2008 at 1:30 p.m. These findings have significant implications for men evaluating treatment options for localized prostate cancer. Using records from 10,333 men treated for localized prostate cancer (6,196 with radical […]
Public release date: 15-May-2008 More than 40 per cent of parents have used cough medicine for children younger than two – even though it is not recommended, nor proven effective for children in this age group, an Australia-first study has found. The joint University of Melbourne and Royal Children’s Hospital study, surveyed 325 parents at hospital outpatient clinics, maternal child health centres and child care centres about their use of over-the-counter medication for children aged 0-24 months. It is the first study in Australia examining the use of over-the-counter medications among parents of children in this age group. […]
Public release date: 15-May-2008 Using newly available data on worldwide cancer incidence, researchers at the Moores Cancer Center at University of California, San Diego (UCSD) and the Department of Family and Preventive Medicine have shown a clear association between deficiency in exposure to sunlight, specifically ultraviolet B (UVB), and breast cancer. UVB exposure triggers photosynthesis of vitamin D3 in the body. This form of vitamin D also is available through diet and supplements. Approximately 1,150,000 cases and 410,000 deaths from breast cancer occur annually worldwide, including 215,000 new cases and 41,000 deaths in the United States. The study is […]
Public release date: 15-May-2008 Study to be presented at the American Society of Clinical Oncology ROCHESTER, Minn. — Researchers in the North Central Cancer Treatment Group (NCCTG) have shown that patients who receive intravenous calcium and magnesium before and after the chemotherapy drug oxaliplatin for the treatment of advanced colon cancer experience a significantly reduced incidence and severity of neurological side effects (neurotoxicity). This reduction increases the likelihood that patients are able to complete a full course of treatment. The findings were released May 15 as part of the 44th annual meeting of the American Society of Clinical […]
Public release date: 16-May-2008 Parental concerns in maintaining germ-free homes for their children have led to an ever-increasing demand and the rapid adoption of anti-bacterial soaps and cleaning agents. But the active ingredients of those antiseptic soaps now have come under scrutiny by the EPA and FDA, due to both environmental and human health concerns. Two closely related antimicrobials, triclosan and triclocarban, are at the center of the debacle. Whereas triclosan (TCS) has long captured the attention of toxicologists due to its structural resemblance to dioxin (the Times Beach and Love Canal poison), triclocarban (TCC) has ski-rocketed in 2004 from […]
Public release date: 18-May-2008 PHILADELPHIA) An herb used in traditional medicine by many Middle Eastern countries may help in the fight against pancreatic cancer, one of the most difficult cancers to treat. Researchers at the Kimmel Cancer at Jefferson in Philadelphia have found that thymoquinone, an extract of nigella sativa seed oil, blocked pancreatic cancer cell growth and killed the cells by enhancing the process of programmed cell death. While the studies are in the early stages, the findings suggest that thymoquinone could eventually have some use as a preventative strategy in patients who have gone through surgery and chemotherapy […]
Public release date: 19-May-2008 Researchers at the University of Illinois report this week that a plant compound found in abundance in celery and green peppers can disrupt a key component of the inflammatory response in the brain. The findings have implications for research on aging and diseases such as Alzheimer’s and multiple sclerosis. The study appears this week in Proceedings of the National Academy of Sciences. Inflammation can be a blessing or a blight. It is a critical part of the body’s immune response that in normal circumstances reduces injury and promotes healing. When it goes awry, however, the inflammatory […]
Public release date: 20-May-2008 ATS 2008, TORONTO—Mothers exposed to farms, particularly to barns and farm milk, while pregnant confer protection from allergies on their newborns, according to a group of German researchers, who will present their findings at the American Thoracic Society’s 2008 International Conference in Toronto on Wednesday, May 21. In a study of the children of 18 farming mothers and 59 non-farming mothers, the researchers believe they have proved their hypothesis that a mother’s farm exposure affects her baby’s T regulatory cells. These cells, it is now believed, act to suppress immune responses and thereby maintain immune system […]
Public release date: 20-May-2008 Probiotic bacteria, defined as living microorganisms that have beneficial effects on human health, have mostly been studied in the prevention and treatment of different gastrointestinal diseases and allergies. Probiotic products, however, are usually consumed by the general, healthy population but not much is known what kind of effects they have on the immune system in healthy adults. It is not clear how probiotics exert their health effects, but one of the most probable action mechanisms is the modulation of immune responses via the gut’s mucosal immune system. The study, performed by the groups of […]
Public release date: 20-May-2008 New study in the FASEB Journal shows how and why molecules released from burning incense in religious ceremonies alleviate anxiety and depression Religious leaders have contended for millennia that burning incense is good for the soul. Now, biologists have learned that it is good for our brains too. In a new study appearing online in The FASEB Journal (http://www.fasebj.org), an international team of scientists, including researchers from Johns Hopkins University and the Hebrew University in Jerusalem, describe how burning frankincense (resin from the Boswellia plant) activates poorly understood ion channels in the brain to alleviate anxiety […]
Public release date: 20-May-2008 BOSTON- (May 20, 2008) In an epidemiological study, Tufts University researchers identified trends of vitamin B6 status in a sample of the United States population based on measures of plasma pyridoxal 5′- phosphate (PLP) levels in the bloodstream. Plasma PLP is the indicator used by the federal government to set the current Recommended Dietary Allowance (RDA) of vitamin B6, a nutrient essential for red blood cell function and important for maintaining a healthy immune system and blood glucose levels. “Across the study population, we noticed participants with inadequate vitamin B6 status even though they reported […]
Public release date: 20-May-2008 Researchers searching for solutions to gastric motility issues following gastric bypass surgery discovered some unexpected results including enhanced weight loss, better GI quality of life and lower Hydrogen (H2) breath test values (which measure the level of hydrogen in the breath to diagnose conditions that cause GI symptoms) with the use of probiotics. A potential complication after gastric bypass surgery is bacterial overgrowth, which may affect gastrointestinal functioning, quality of life and weight loss. In an attempt to combat this bacterial overgrowth and its consequences, patients in this study were given probiotics to restore a good […]
Public release date: 20-May-2008 Professor Yi-Yang Hu and his colleagues confirmed that Jianpi Huoxue decoction (JHD) reduced the cytokine expression induced by lipopolysaccharide (LPS) and inhibited some targets in LPS-activated Kupffer cell signal pathway. This may provide new insight on the mechanism of JHD on alcoholic liver injury. This study, performed by a team led by Professor Hu, from the Institute of Liver Diseases, Shuguang Hospital, affiliated with the Shanghai University of Traditional Chinese Medicine,is described in a research article to be published on March 28, 2008 in the World Journal of Gastroenterology. This study confirmed one of the […]
Public release date: 21-May-2008 ATS 2008, TORONTO — Scientists believe they may have identified a biological explanation for the link between cesarean-section delivery and risk of allergy and asthma in childhood. They will present their findings at the American Thoracic Society’s 2008 International Conference in Toronto on Tuesday, May 20. Several studies have shown immunological differences between children with and without allergy at the time of birth. For example, increased cord blood levels of IL-13, a Th2 type cytokine, have been positively associated with allergy among children with a family history of allergy Regulatory T cells are a subgroup of […]
Public release date: 22-May-2008 New research in the Society of Chemical Industry’s Journal of the Science of Food and Agriculture shows that oregano oil works as well as synthetic insecticides to combat infestation by a common beetle, Rhizoppertha dominica, found in stored cereals. Not only does oregano oil work as well as synthetic versions but it has none of the associated side effects of synthetic insecticides on the environment. Growing resistance to synthetic insecticides combined with potential environmental damage and new government directives on changes to the way chemicals are registered means that scientists are increasingly looking at natural alternatives […]
Public release date: 22-May-2008 CHICAGO (May 22, 2008) – What common oral condition appears as shallow ulcers of different sizes, affects one in five Americans, can be caused by food allergies and hormonal changes, and also can cause severe mouth pain? Commonly referred to as “canker sores,” recurrent aphthous ulcers (RAU) now can be treated by an extract in licorice root herbal extract, according to a study published in the March/April 2008 issue of General Dentistry, the Academy of General Dentistry’s (AGD) clinical, peer-reviewed journal. The authors examined the effects of an over-the-counter medicated adhesive patch (with extract from […]
Public release date: 23-May-2008 Sea buckthorn (Hippophae rhamnoides) berries are well known for their cholesterol busting properties, but scientists in India say that its leaves are also rich in anti-oxidants and may help ward off liver disease, according to new research due to be published in the Society of Chemical Industry’s (SCI) Journal of the Science of Food and Agriculture. Indigineous to the mountainous regions of China and Russia, sea buckthorn has been shown to be rich in vitamin C, vitamin E, flavonoids and essential fatty acids. The leaves are also used to make a tea. In a clinically […]
