GPRC5A gene found to be a tumor-suppressor for lung cancer

The GPRC5A gene, which is under-expressed in human lung cancer cells, suppresses lung tumors in mouse models and could provide a key to attacking lung cancer in humans, researchers at The University of Texas M. D. Anderson Cancer Center report in the Nov. 21 edition of The Journal of the National Cancer Institute.

New drug may restore memory with Alzheimer's disease

A 2006 study by MetLife found that adults over age 55 fear Alzheimer's disease more than cancer, and with good reason. Alzheimer's creeps up on patients and their families, robbing more than half of all Americans over age 85 of their memory and ability to care for themselves.

HIV drug resistance risk in mothers reduced by tenofovir/emtricitabine with nevirapine during labor

New research from the University of Alabama at Birmingham (UAB) shows that adding a single dose of two common anti-HIV drugs can prevent HIV-positive pregnant women from developing resistance to an entire class of drugs, potentially improving future treatment options.

Implanting myoblasts may improve severe urinary incontinence

Estimates are that up to 70 million people worldwide may be suffering from severe urinary incontinence. A major cause of urinary incontinence is a deficiency of the urethral sphincter muscle, often associated with trauma during child birth, resulting from prostate surgery, or due to aging.

Diet low in carbohydrates may stunt prostate tumor growth

A diet low in carbohydrates may help stunt the growth of prostate tumors, according to a new study led by Duke Prostate Center researchers. The study, in mice, suggests that a reduction in insulin production possibly caused by fewer carbohydrates may stall tumor growth.

What happens when alcohol-dependent subjects view alcohol associated pictures?

Several studies demonstrated that alcohol-dependent patients show altered responses to alcohol-related cues. It is assumed that the regular association of these cues with the ingestion of alcohol leads to conditioned reactions, motivating reward or relief craving and instigating drug intake.

Synthetic compound promotes death of lung-cancer cells, tumors

Human lung-cancer tumors grown in mice have been shown to regress or disappear when treated with a synthetic compound that mimics the action of a naturally occurring "death-promoting" protein found in cells, researchers at UT Southwestern Medical Center report.
