WORCESTER, Mass.— Researchers at the University of Massachusetts Medical School report in the journal Nature Medicine on a cellular pathway in the deadly brain cancer malignant glioma, a pathway essential to the cancer's ability to grow – and a potential target for therapy that would stop the cancer's ability to thrive.

New Rochelle, NY, May 25, 2010—An insightful and in-depth presentation of the most up-to-date clinical and research findings and historical perspectives on pediatric interstitial lung disease (ILD) is presented in a special issue published online ahead of print in Pediatric Allergy, Immunology, and Pulmonology (PED), a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com). The entire issue is available free online. (www.liebertpub.com/ped)
A defective, mutant strain of the bacterium that causes gum disease could provide a clue to potential treatments for Alzheimer's, Parkinson's and a number of other diseases. Researchers from the University of Florida College of Dentistry report their findings today at the 110th General Meeting of the American Society for Microbiology in San Diego.
A Montreal study finds heterotrophic bacteria counts, in more than 70 percent of bottled water samples, exceed the recommended limits specified by the United States Pharmacopeia (USP). Researchers from Ccrest laboratories report their results today at the 110th General Meeting of the American Society for Microbiology in San Diego.
In a discovery that seems counterintuitive, a study appearing in the May 21st Journal of Biological Chemistry has found that tendons in high-stress and strain areas, like the Achilles tendon, actually repair themselves less frequently than low-stress tendons. This study sheds some light on the increased susceptibility of certain tendons to injury during aging.
It is time to change the policy that bans blood donations in Canada from all men who have sex with men, states an article (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj091476.pdf in CMAJ (Canadian Medical Association Journal) www.cmaj.ca.
Since 1983, blood agencies in Canada, the United States and many other industrialized nations have disallowed all blood donations from men who have sex with men (MSM.) While a total ban was justified scientifically and ethically in 1983, in 2010 it no longer makes sense, say pioneering AIDS researchers Dr. Mark Wainberg and Dr. Norbert Gilmore in an article to be published May 25 in the Canadian Medical Association Journal (CMAJ.)
A collaborative research team led by Queen's University biologists has found that potent metals like mercury and lead, ingested by Arctic seabirds feeding in the ocean, end up in the sediment of polar ponds.
A study conducted by researchers at the Cleveland Clinic finds that patients suffering from cirrhosis preceded by nonalcoholic steatohepatitis are at an equal risk of developing hepatocellular carcinoma than those who develop cirrhosis resulting from hepatitis C virus (HCV). Results of this study appear in the June issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD).
The disease-causing bacterium E. coli O157:H7 is present but rare in some wildlife species of California's agriculturally rich Central Coast region, an area often referred to as the nation's "salad bowl," reports a team or researchers led by a UC Davis scientist.
Researchers at Mount Sinai School of Medicine have developed a new influenza vaccine that brings science one step closer to a universal influenza vaccine that would eliminate the need for seasonal flu shots. The new findings can be found in the inaugural issue of mBio®, the first online, open-access journal published by the American Society for Microbiology.
COLUMBUS, Ohio – A study examining the relationship between body mass index (BMI) and illness suggests that a BMI of 30 or above, a signal of obesity according to federal health standards, does not translate into current illness among adults under age 40.
In addition, researchers found that across all age groups studied, from 25 to 70 years, there was little difference in the current health status in normal-weight vs. overweight people based on the medications they took.
We've all heard about the importance of raising HDL, or the so-called "good" cholesterol, and lowering LDL, or "bad" cholesterol, to improve heart health. While we've come to assume HDL cholesterol is an inherently good thing, a new study shows that for a certain group of patients, this is not always the case. The study is the first to find that a high level of the supposedly good cholesterol places a subgroup of patients at high risk for recurrent coronary events, such as chest pain, heart attack, and death.
BOSTON (May 25, 2010) — Longtime environmental health researchers at Tufts University School of Medicine describe the carcinogenic effects of endocrine-disrupting chemicals (EDCs), ubiquitous chemicals that have hormone-like effects in the body. In a review article published online May 25 in Nature Reviews Endocrinology, the researchers express the need for more complex strategies for studying how these chemicals affect health but report that ample evidence already supports changing public health and environmental policies to protect the public from exposure to EDCs.
TORONTO, Ont., May 25, 2010 _ Almost half the high schools in Toronto do not teach students how to perform cardio-pulmonary resuscitation (CPR), even though it's part of the Grade 9 curriculum and studies have shown it can greatly increase the survival rates of people who suffer heart attacks outside of hospitals.
Only 6 per cent of high schools schools train students to use an automatic external defibrillator (AED), which is found in less than half the schools, according to a survey by researchers at St. Michael's Hospital.
