Study reveals that glial cells are integral to brain function

New research by scientists at UC San Francisco shows that one of the brain's fundamental self-protection mechanisms depends on coordinated, finely calibrated teamwork among neurons and non-neural cells knows as glial cells, which until fairly recently were thought to be mere support cells for neurons.

Final patient completion of phase II study of TR040303 in patients treated for acute myocardial infarction announced by Trophos

Trophos SA, a clinical stage pharmaceutical company developing innovative therapeutics from discovery to clinical validation for indications with under-served needs in neurology and cardiology, announces today the final patient completion of a phase II study of TR040303 in patients treated for acute myocardial infarction (MI). Outcome data of this study is expected to be available towards the end of 2013.

Life-prolonging effect of vitamin niacin demonstrated in roundworms

Who would not want to live a long and healthy life? A freely available food supplement could help in this respect, scientists from ETH Zurich have demonstrated in roundworms. Vitamin B3 - also known as niacin - and its metabolite nicotinamide in the worms' diet caused them to live for about one tenth longer than usual.

Shortage of zinc may contribute to diseases like Alzheimer's and Parkinson's

Scientists at the University of Wisconsin-Madison have made a discovery that, if replicated in humans, suggests a shortage of zinc may contribute to diseases like Alzheimer's and Parkinson's, which have been linked to defective proteins clumping together in the brain.

Compounds found in red wine and green tea can be used as antibacterial coating

A simple kitchen sink experiment helped Northwestern University researchers discover that green tea leaves not only can be used to steep a good cup of tea, but they make an excellent antibacterial coating, too.

Anti-oxidants have great potential as treatment for neuropathic pain

Neuropathic pain - pain that results from a malfunction in the nervous system - is a daily reality for millions of Americans. Unlike normal pain, it doesn't go away after the stimulus that provoked it ends, and it also behaves in a variety of other unusual and disturbing ways. Someone suffering from neuropathic pain might experience intense discomfort from a light touch, for example, or feel as though he or she were freezing in response to a slight change in temperature.

Researchers reveal how SMIP004 anticancer compound targets prostate cancer cells

One major hallmark of cancer cells is their ability to survive under stressful conditions. A new study spearheaded by researchers at Sanford-Burnham Medical Research Institute reveals how a promising anticancer compound called SMIP004 specifically kills prostate cancer cells by compromising their ability to withstand environmental stress.

Resveratrol counteracts exercise benefits in older men

In older men, a natural antioxidant compound found in red grapes and other plants -- called resveratrol -- blocks many of the cardiovascular benefits of exercise, according to research published today [22 July 2013] in The Journal of Physiology.

TAp73 protein frequently overexpressed in wide range of human tumors

They say you can pick your friends, but not your family. The same may hold true for related proteins. The protein TAp73 is a relative of the well-known, tumor-suppressor protein p53. It shares extensive common gene sequences with p53 and, as suggested by some previous studies, it may function similar to p53 to prevent tumor formation.

Treating bacteria with silver compounds boosts efficacy of old antibiotics

Slipping bacteria some silver could give old antibiotics new life, scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University reported June 19 in Science Translational Medicine.

Researchers uncover DNA damage checkpoint used by cells to monitor oxidatively damaged DNA

In current health lore, antioxidants are all the rage, as "everybody knows" that reducing the amount of "reactive oxygen species" -- cell-damaging molecules that are byproducts of cellular metabolism -- is critical to staying healthy. What everyone doesn't know is that our bodies already have a complex set of processes built into our cells that handle these harmful byproducts of living and repair the damage they cause.

Cinnamon compounds show some promise in the effort to fight Alzheimer's disease

Cinnamon: Can the red-brown spice with the unmistakable fragrance and variety of uses offer an important benefit? The common baking spice might hold the key to delaying the onset of -- or warding off -- the effects of Alzheimer's disease.

Study shows PDH enzyme plays a major role in regulation of oncogene-induced cellular senescence

An article published on the journal Nature describes the major role that Pyruvate dehydrogenase (PDH) —an enzyme of cellular energy metabolism— plays in the regulation of the cellular senescence induced by the oncogene BRAF, which usually appears mutated in melanoma and other cancers.

Vitamin C kills drug-resistant TB bacteria in lab

In a striking, unexpected discovery, researchers at Albert Einstein College of Medicine of Yeshiva University have determined that vitamin C kills drug-resistant tuberculosis bacteria in laboratory culture.

New research reveals how endothelium maintains highly efficient barrier function

The endothelium, the cellular layer lining the body's blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body's circulatory system.

Evidence shows progerin induced by ultraviolet light is responsible for premature skin aging

A study conducted by researchers at Boston University School of Medicine (BUSM) provides new evidence that longwave ultraviolet light (UVA) induces a protein that could result in premature skin aging.
