Low dose bisphenol-A exposure shows significant reproductive health effects in rats

New research from North Carolina State University and the National Institute of Environmental Health Sciences (NIEHS) shows significant reproductive health effects in rats that have been exposed to bisphenol-A (BPA) at levels equivalent to or below the dose that has been thought not to produce any adverse effects.

Animal model for human gambling

UBC researchers have created the world's first animal laboratory experiment to successfully model human gambling. The advance will help scientists develop and test new treatments for gambling addictions, a devastating condition that affects millions worldwide.

Neuroimaging shows how we recognize right and wrong

A recent neuroimaging study reveals that the ability to distinguish true from false in our daily lives involves two distinct processes. Previous research relied heavily on the premise that true and false statements are both processed in the left inferior frontal cortex.

Genome-wide map shows precisely where microRNAs do their work

MicroRNAs are the newest kid on the genetic block. By regulating the unzipping of genetic information, these tiny molecules have set the scientific world alight with such wide-ranging applications as onions that can't make you cry and therapeutic potential for new treatments for viral infections, cancer and degenerative diseases. But the question remains: How do they work?

“Life force” linked to body’s ability to withstand stress

Our ability to withstand stress-related, inflammatory diseases may be associated, not just with our race and sex, but with our personality as well, according to a study published in the July issue of the journal Brain, Behavior and Immunity. Especially in aging women, low levels of the personality trait extraversion may indicate that blood levels of a key inflammatory molecule have crossed over a threshold linked to a doubling of risk of death within five years.

New diagnostic technique detects possible Alzheimer's biomarker in blood

A new diagnostic technique which may greatly simplify the detection of Alzheimer's disease has been discovered by researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital (JGH).

Discovery of the cell's water gate may lead to new cancer drugs

The flow of water into and out from the cell may play a crucial role in several types of cancer. Scientists at the University of Gothenburg have now found the gate that regulates the flow of water into yeast cells.

New understanding on how "trans fats" gum up cellular machinery

Partially hydrogenated vegetable oils in processed foods contain trans fatty acids that interfere with the regulation of blood flow. A new report reveals a new way in which these "trans fats" gum up the cellular machinery that keeps blood moving through arteries and veins.

Minimally invasive treatment of brain tumors on the horizon

Duke University engineers have taken a first step toward a minimally invasive treatment of brain tumors by combining chemotherapy with heat administered from the end of a catheter.

Tai Chi shows positive health benefits for arthritis

A new study by The George Institute for International Health has found Tai Chi to have positive health benefits for musculoskeletal pain. The results of the first comprehensive analysis of Tai Chi suggest that it produces positive effects for improving pain and disability among arthritis sufferers.

Simple blood test detects molecular marker of aging in humans

In 2004, researchers at the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center announced a crucial discovery in the understanding of cellular aging. They found that as cells and tissues age, the expression of a key protein, called p16INK4a, dramatically increases in most mammalian organs. Because p16INK4a is a tumor suppressor protein, cancer researchers are interested in its role in cellular aging and cancer prevention.

Telehealth interventions for the secondary prevention of coronary heart disease

The use of phone and internet between patients and healthcare providers is an effective way to reduce risk factors for coronary heart disease and the risk of further events after a heart attack, according to new research published today in the June issue of the European Journal of Cardiovascular Prevention & Rehabilitation.

Much touted "depression risk gene" may not add to risk after all

Stressful life events are strongly associated with a person's risk for major depression, but a certain gene variation long thought to increase risk in conjunction with stressful life events actually may have no effect, according to researchers funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health. The study, published in the June 17, 2009, issue of the Journal of the American Medical Association, challenges a widely accepted approach to studying risk factors for depression.

Income, education, important factors in heart disease risk

Doctors who ignore the socioeconomic status of patients when evaluating their risk for heart disease are missing a crucial element that might result in inadequate treatment, according to a University of Rochester Medical Center study published in the June 2009 American Heart Journal.

Cannabis smoke damages DNA – cancer risks

A new study published by University of Leicester researchers has found "convincing evidence" that cannabis smoke damages DNA in ways that could potentially increase the risk of cancer development in humans.

Histamine affects alcohol-related behaviour

The histamine-3 receptor is important in terms of alcohol-related behaviour, and a drug affecting that receptor may have qualities that alter alcohol-related behaviour.
