Selenium may slow march of AIDS

Increasing the production of naturally occurring proteins that contain selenium in human blood cells slows down multiplication of the AIDS virus, according to biochemists.

Genetic variation in metabolism identified

Metabolic diseases - in particular the increasingly prevalent type 2 diabetes - are caused by a complex interaction between genetic disposition and unfavorable lifestyle, above all unbalanced diet and too little physical exercise.

Study identifies genetic variants giving rise to differences in metabolism

Common genetic polymorphisms induce major differentiations in the metabolic make-up of the human population, according to a paper published November 28 in the open-access journal PLoS Genetics.

Fear of hypoglycemia a barrier to exercise for type 1 diabetics

According to a new study, published in the November issue of Diabetes Care , a majority of diabetics avoid physical activity because they worry about exercise-induced hypoglycemia (low blood sugar) and severe consequences including loss of consciousness.

Defective calcium metabolism in nerve cells contributes to neurological disorder

Defective calcium metabolism in nerve cells may play a major role in a fatal genetic neurological disorder that resembles Huntington's disease, researchers at UT Southwestern Medical Center have found in a mouse study.

Improvement seen regarding racial disparities for liver transplantation, disparities for women remain

Following introduction of a new system in 2002 to determine the allocation of donated livers, black patients no longer are less likely to receive a liver transplant, but disparities for women remain, according to a study in the November 26 issue of JAMA, the Journal of the American Medical Association.

Adiponectin is a metabolic link between obesity and bone mineral density

Researchers at the University of Toronto, Faculty of Medicine, Toronto, Canada, have discovered that adiponectin, a protein secreted from adipocytes, is a metabolic link that can explain, in part, the known positive relationship between obesity and both bone mineral density and reduced susceptibility to fractures.

Researchers find clue to safer obesity drugs

Once hailed as a miracle weight-loss drug, Fen-phen was removed from the market more than a decade ago for inducing life-threatening side effects, including heart valve lesions. Scientists at UT Southwestern Medical Center are trying to understand how Fen-phen behaves in the brain in order to develop safer anti-obesity drugs with fewer side effects.

A potential new procedure for treating obesity

Lining the upper portion of the small intestine with an impermeable sleeve led to both weight loss and restoration of normal glucose metabolism in an animal model of obesity-induced diabetes.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

Heart patients are often not treated in accordance with guidelines

Many patients with cardiovascular disease are not given adequate drug therapy.

FDA approves tapentadol immediate-release tablets for pain in adults

Millions of Americans with moderate to severe acute pain and their health-care providers will soon have a new treatment option.

Non-pharmacologic interventions for the control of osteoporosis and obesity

The Department of Biomedical Engineering at Stony Brook University received a $1.8 million grant from the National Institutes of Health (NIH) to investigate the biologic and physical mechanisms of very low-magnitude mechanical signals and how they strengthen bone and muscle.

Lactic acid found to be important energy source for tumor cells

Many tumors have cells that burn fuel for activities in different ways. Tumor cells near blood vessels have adequate oxygen sources and can either burn glucose like normal cells, or lactic acid (lactate). Tumor cells further from vessels are hypoxic and inefficiently burn a lot of glucose to keep going. In turn, they produce lactate as a waste product.

Light drinking has certain health benefits, researchers look at why

While the physiological damage and social havoc created by alcohol abuse and dependency are well-known, it is also true that light-to-moderate drinking has certain health benefits.

Study identifies causes of bone loss in breast cancer survivors

Osteoporosis is a growing concern among breast cancer survivors and their doctors, because certain cancer drugs can cause bone loss.

Discovery of 13 new tumor-suppressor genes in liver cancer

Over the years, hunting for cancer-related genes and understanding how they work has been an important, although time-consuming, exercise.

Reduced-calories and exercise can modify a postmenopausal woman's risk of breast cancer

Scientists at the University of Texas at Austin have identified pathways by which a reduced-calorie diet and exercise can modify a postmenopausal woman's risk of breast cancer.

Antibiotics can cause pervasive, persistant changes to microbiota in human gut

Using a novel technique developed by Mitchell Sogin of the Marine Biological Laboratory (MBL) to identify different types of bacteria, scientists have completed the most precise survey to date of how microbial communities in the human gut respond to antibiotic treatment.
