Cocaine abuse may increase risk of Parkinson's disease

Adults who abuse cocaine might increase their risk of developing Parkinson's disease (PD), and pregnant women who abuse cocaine could increase the risk of their children developing PD later in life, according to results of laboratory studies performed by investigators at St. Jude Children's Research Hospital.

New insights into treatment of hypertension in black Americans

Researchers have reported a possible explanation for the higher risk of heart disease and its complications among black Americans, along with a way of treating this condition.

Six gene variants predict heart muscle damage after cardiac surgery

Duke University Medical Center researchers have found that patients with six specific variants of genes involved in the body's immune response are significantly more likely to suffer damage of heart tissue after cardiac surgery.

Lifelong exercise decreases cellular aging in the brain

In the first study to show that lifelong exercise decreases cellular aging in the brain, scientists from the McKnight Brain Institute of the University of Florida say that moderately active rats have healthier DNA and more robust brain cells than their less active counterparts. The research was presented at the Society for Neuroscience's 35th annual meeting in Washington, D.C.

High blood glucose levels early in pregnancy deprive the embryo of oxygen

The babies of women with diabetes are two to five times more likely to develop birth defects than offspring of women without the disease.

Plant-derived compounds appear to block the activity of an enzyme that triggers inflammation in joints

The findings came to light while the researchers were studying the wildly different ways in which cells in human blood vessels and joints respond to pressure gradients generated from liquid moving along their surface, a force called shear stress.

Green tea may protect the brain against Alzheimer's disease

Researchers at the University of South Florida (USF) have found that green tea may offer another potential health benefit - protecting the brain against the ravages of Alzheimer's disease.

Molecular pathway in mice that makes prostate cells vulnerable to cancer-causing oxygen damage

Scientists from Maryland and New Jersey have identified a molecular pathway in mice that makes prostate cells vulnerable to cancer-causing oxygen damage.

Call for more donations of brains to help researchers discover new treatments for neurological disorders

Speaking at the BA Festival of Science, at Trinity College, Dublin, Dr Kirstin Goldring from Imperial College London and Charing Cross Hospital is calling for more donations of brains to help researchers discover new treatments for neurological disorders.

Ways to avoid hazards of heart bypass under study

The heart-lung bypass machine that stills the heart while surgeons bypass an adult’s clogged arteries or repair a baby’s malformed heart can also trigger a potentially deadly inflammatory response.

UCI study helps identify one reason why women have lower stroke risk than men

Estrogen's role as an inhibitor of toxic-free radicals in cerebral blood vessels may be a key reason why premenopausal women have a lower stroke risk than men.

Rotenone study may lead to novel therapies for Parkinson's disease

Neuroscientists from the University at Buffalo have described for the first time how rotenone, an environmental toxin linked specifically to Parkinson's disease, selectively destroys the neurons that produce dopamine, the neurotransmitter critical to body movement and muscle control.

The wonders of watermelon

On a hot summer day, nothing refreshes quite like a crisp, juicy slice of cool watermelon. Whether you're chomping into watermelon, enjoying it as part of a fruit salad or slurping on a watermelon smoothie, that red pulp provides a powerhouse of nutritional value.

Single hit of meth damages fetal development in mice

Canadian scientists have found from animal experiments, that just one single exposure to methamphetamine during fetal development induces DNA damage in the brain and increases the risk of long-term abnormal motor development.

Aging and gene expression in the primate brain

While medical science and a healthy lifestyle can help increase life expectancy, many aspects of aging and longevity are beyond our control. Published this week in the open-access journal PLoS Biology, Michael Eisen and colleagues shed light on these genetic factors by identifying sets of genes whose expression changes with age in human and chimp brains.

New way to prevent macular degeneration

Two studies from an unusual research partnership at the University of Chicago appear to have resolved a long-standing dispute about the role of melanin in the eye. The studies, one published in the Proceedings of the National Academy of Sciences (PNAS) and one early online in the Journal of the American Chemical Society (JACS), also suggest a new way to prevent a common cause of blindness.

Single prenatal dose of methamphetamine enough to cause long-term neurodevelopmental problems in babies

In research published in the August issue of Free Radical Biology and Medicine, U of T pharmacy and pharmacology professor Peter Wells and his colleagues determined that exposing pregnant mice only once to methamphetamine led to delivery of offspring with long-term neurodevelopmental problems, including reduced motor co-ordination.

New theory on aging says popping pills and drinking orange juice no guarantee you'll live longer

In direct contrast to previous reports, researchers now say that drinking gallons of orange juice and popping vitamin pills may not be a guarantee that you will live longer.
