Cardiac stent patients with diabetes may benefit from drug that counteracts the effects of leptin
The naturally high levels of leptin in diabetic patients may reduce the effectiveness of drug-eluting stents used to treat heart blockages, but using a chemical that differs from the one commonly used to coat stents could counteract this effect. view more (2008-12-18)
UT Southwestern researchers develop new strategy for broad spectrum anti-viral drugs
Bavituximab, an anti-viral drug developed by UT Southwestern Medical Center researchers, shows promise as a new strategy to fight viral diseases, including potential bioterrorism agents. view more (2008-11-24)
Nontoxic nanoparticle can deliver and track drugs
A nontoxic nanoparticle developed by Penn State researchers is proving to be an all-around effective delivery system for both therapeutic drugs and the fluorescent dyes that can track their delivery. view more (2008-11-19)
Researchers uncover molecule that keeps pathogens like salmonella in check
Scientists at UT Southwestern Medical Center have found a potential new way to stop the bacteria that cause gastroenteritis, tularemia and severe diarrhea from making people sick. view more (2008-08-22)
Obesity predisposition traced to the brain's reward system
The tendency toward obesity is directly related to the brain system that is involved in food reward and addictive behaviors, according to a new study. view more (2008-07-30)
UT Southwestern researchers identify new targets for RNAs that regulate genes
Tiny strands of genetic material called RNA - a chemical cousin of DNA - are emerging as major players in gene regulation, the process inside cells that drives all biology and that scientists seek to control in order to fight disease. view more (2008-07-07)
UIC researchers make promising finding in severe lung disease
Researchers at the University of Illinois at Chicago have identified a novel function for an enzyme that plays a role in the tissue injury in acute respiratory distress syndrome, also known as ARDS. view more (2008-06-30)
Complex Changes in the Brain's Vascular System Occur after Menopause
Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don't notice can be more dangerous. view more (2008-06-17)
Vitamin D findings point to new treatment for heart failure
Strong bones, a healthy immune system, protection against some types of cancer: Recent studies suggest there's yet another item for the expanding list of Vitamin D benefits. view more (2008-06-12)
U of M researchers discover gene linked to adult-onset obesity
Researchers at the University of Minnesota have discovered a gene that may provide a clue as to why obesity rates increase with age. The research was published today in the Proceedings of the National Academy of Sciences. view more (2008-06-11)
New Mount Sinai research tracks effects of addictive drugs on brain
Mount Sinai researchers may have unlocked the key to better understanding the effect addictive drugs have on the human brain. view more (2008-05-16)
Child abuse may 'mark' genes in the brains of suicide victims
A team of McGill University scientists has discovered important differences between the brains of suicide victims and so-called normal brains. Although the genetic sequence was identical in the suicide and non-suicide brains, there were differences in their epigenetic marking - a chemical coating influenced by environmental factors. view more (2008-05-07)
Brain study may lead to improved epilepsy treatments
Using a rodent model of epilepsy, researchers found one of the body's own neurotransmitters released during seizures, glutamate, turns on a signaling pathway in the brain that increases production of a protein that could reduce medication entry into the brain. view more (2008-04-15)
First do no harm? UH prof taking opposite approach to treat asthma
One month of tough breathing may help asthma sufferers breathe easier in the long run, according to research from one University of Houston professor. view more (2008-04-10)
Protein data bank archives 50,000th molecule structure
The Protein Data Bank (PDB) based at Rutgers, The State University of New Jersey, and the University of California-San Diego (UCSD) this month reached a significant milestone in its 37-year history. The 50,000th molecule structure was released into its archive, joining other structures vital to pharmacology, bioinformatics and education. view more (2008-04-09)
Animal research suggests new strategy for treating cocaine addiction
New research in monkeys suggests the feasibility of treating cocaine addiction with a "replacement" drug that mimics the effects of cocaine but has less potential for abuse - similar to the way nicotine and heroin addictions are treated. view more (2008-04-07)
Environmental enrichment can reduce cocaine use, researchers find
Simple environmental enrichment and increased social stress can both affect the level of individual drug use, according to new monkey research at Wake Forest University School of Medicine. view more (2008-04-07)
A search for protection against chemotherapy cardiotoxicity
Researchers at the University of Grenoble, in France, have discovered that erythropoietin administration prevents acute cardiotoxic effects induced by doxorubicin and trastuzumab exposures. view more (2007-12-21)
Research Reveals Secrets of Alcohol's Effect on Brain Cells
Alcohol triggers the activation of a variety of genes that can influence the health and activity of brain cells, and new research from Weill Cornell Medical College in New York City sheds light on how that process occurs. view more (2007-12-10)
Dartmouth researchers show effects of low dose arsenic on development
A team of Dartmouth Medical School (DMS) researchers has determined that low doses of arsenic disrupt the activity of a hormone critical in development. view more (2007-11-15)
