Cardiovascular disease impact varies according to age, gender, other factors

Cardiovascular disease deaths have declined in the last 25 years, but the effect of America's No. 1 killer varies greatly based on gender, age, location and type, according to a study reported in Circulation: Journal of the American Heart Association.

Smokers more likely to receive jolt from defibrillators

If some patients with heart disease don't take their doctor's advice to quit smoking, they are probably going to get "shocking" reminders.

Gene silencing protein discovered

A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off -in this case, the turning off of thousands of nearly identical genes in a hybrid plant.

Novel protein JHDM2A offers new look at male hormone regulation

For the second time in less than a year, University of North Carolina at Chapel Hill scientists have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent.

New approaches to genetic disease, based on cells' own ability to correct themselves

New approaches to genetic disease, based on cells' own ability to correct themselves, will be outlined today at the annual conference of the European Society of Human Genetics in Amsterdam, The Netherlands.

Research into tiny muscle movements proves useful in anti-terror investigations

When trying to lie your way through any situation, keep a tight rein on your zygo maticus major and your orbicularis oculi. They'll give you away faster than a snitch.

fMRI used to show dread responses in brain

In order to better understand how people make decisions when the outcomes are known to be unpleasant, a team of Emory neuroscientists led by Gregory Berns, MD, PhD, used functional magnetic resonance imaging (fMRI) to determine the areas of the brain that are activated when someone experiences dread.

Mutated gene leads to JSRD

The research team, directed by Joseph Gleeson, M.D., Director of the Neurogenetics Laboratory at the UCSD School of Medicine and associate professor in the Department of Neurosciences, have identified a new gene that, when mutated, leads to JSRD. Their findings will be published on-line in advance of publication in the journal Nature Genetics.

The efficacy and safety of Rituximab in patients with active rheumatoid arthritis

Drugs aimed at suppressing inflammation-provoking cytokines--specifically those linked to T-cells--have improved the treatment of rheumatoid arthritis (RA), a chronic, inflammatory autoimmune disease. Still, the frequency of remission achieved by these biologic agents remains below 50 percent.

Combination of genetic mutation and viral infection may cause prostate cancer

Significant recent interest in the literature (JAMA 2006;295:1503, Lancet, epub) and by patients has arisen in response to a presentation given by Dr. Eric Klein of the Cleveland Clinic at the 2006 Prostate Cancer Symposium in San Francisco, February 24, 2006.

Many children still exposed at home to tobacco smoke - exposure linked to behavioral problems

According to research in the U.S. even though most Americans are in agreement with smoking restrictions in public places, many adults still expose their children to significant health risks by smoking cigarettes at home.

Antidepressant suicide risk up five times for seniors

According to Canadian researchers seniors who are prescribed antidepressants such as Prozac, Paxil and Zoloft are almost five times more likely to commit suicide during the first month on the drugs than those given other medication to treat depression.

Exposure to cocaine before birth not linked to bad behavior in kids

Toddlers exposed to cocaine before birth exhibit no more behavioral problems than other children their age, despite early predictions that "crack babies" would grow up to be delinquents, University of Florida researchers say.

Men with low estrogen levels have an increased risk for future hip fracture

A new study has found that men with low estrogen levels have an increased risk for future hip fracture, and those with both low estrogen and low testosterone levels have the greatest risk.

New study describes molecular basis of NeuroAIDS

Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus.

Men find masculine men more threatening during their partner's ovulation phase

Men become more jealous of dominant males when their female partner is near ovulation, researchers at the University of Liverpool have found.

Amyloid protein content in the brain linked to Alzheimer's disease risk

Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the University of Antwerp are the first to show that the quantity of amyloid protein in brain cells is a major risk factor for Alzheimer's disease. Amyloid protein has already been known to be the primary component of the senile plaques in the brains of patients. The new discovery demonstrates that the greater the quantity of the protein that is produced, the younger the dementia patient is.
