Inherited impulsivity predicts alcoholism

Solving the age-old chicken and the egg dilemma, Indiana University-Purdue University Indianapolis researchers report that genetic predisposition to impulsivity is a trait predictive of alcoholism. The study appears on the July print issue of the journal Alcoholism: Clinical and Experimental Research, available online on April 22.

Researchers discover that gene switches on during development of epilepsy

A discovery made by researchers at Wake Forest University School of Medicine while studying mice may help explain how some people without a genetic predisposition to epilepsy can develop the disorder.

In-body stem cell therapy has enormous potential for bone injuries

Rarely will physicians use the word "miraculous" when discussing patient recoveries. But that's the very phrase orthopaedic physicians and scientists are using in upstate New York to describe their emerging stem cell research that could have a profound impact on the treatment of bone injuries. Results from preliminary work being released today, patients confined to wheelchairs were able to walk or live independently again because their broken bones finally healed.

Link found between vitamin D insufficiency and asthma severity

Serum levels of vitamin D in more than 600 Costa Rican children were inversely linked to several indicators of allergy and asthma severity, including hospitalizations for asthma, use of inhaled steroids and total IgE levels, according to a study that will appear in the first issue for May of the American Journal of Respiratory and Critical Care Medicine.

NSAIDs do not prevent Alzheimer's disease or other forms of dementia

A new study shows that nonsteroidal anti-inflammatory drugs (NSAIDs), such as the pain relievers ibuprofen and naproxen, do not prevent Alzheimer's disease or other forms of dementia.

Liquid calorie intake a big cause of weight gain

Liwei Chen, MD, PhD, Assistant Professor of Epidemiology at the LSU Health Sciences Center New Orleans School of Public Health, is the lead author of a research paper showing that weight gain and obesity are more linked to an increase in liquid calories, particularly sugar-sweetened beverages, than calories from solid food.

Lymphocytes promote cancer spread

Researchers at the UC San Diego School of Medicine and the Moores UCSD Cancer Center have new evidence that a type of immune system cell thought to be part of the first line of defense against breast cancer may also help promote its spread.

Mitochondrial peptide Humanin linked to neuronal cell survival and regulation of glucose metabolism

Recent studies have shown that the mitochondrial peptide Humanin (HN) protects against neuronal cell death such as happens in Alzheimer's disease.

Genes influence impulsivity, which may then contribute to risk for developing alcoholism

Numerous studies have shown that highly impulsive behavior - defined as the tendency to choose small, immediate rewards over larger, delayed rewards - is more prevalent in drug addicts and alcoholics compared to individuals without addictions.

Double-lung transplants work better than single for long-term survival

Having both lungs replaced instead of just one is the single most important feature determining who lives longest after having a lung transplant, more than doubling an organ recipient's chances of extending their life by over a decade, a study by a team of transplant surgeons at Johns Hopkins shows.

Binge drinking may be detrimental to the developing adolescent brain

A study of adolescent binge drinkers has found that even relatively infrequent exposure to large amounts of alcohol during the teen years may compromise the integrity of the brain's white matter, which is critical for the efficient relay of information within the brain.
