Plant sterols to lower cholesterol have risks

Plant sterols have been touted as an effective way to lower cholesterol and reduce the risk of heart disease. However, a research study in the July JLR has uncovered that these compounds do have their own risks, as they can accumulate in heart valves and lead to stenosis.

Researchers step closer to delivering cancer-killing drugs to pediatric brain tumors

An interdisciplinary team of researchers at Washington University in St. Louis, led by Karen L. Wooley, Ph.D., James S. McDonnell Distinguished University Professor in Arts & Sciences, is a step closer to delivering cancer-killing drugs to pediatric brain tumors, similar to the tumor that Senator Ted Kennedy is suffering from.

Tired B cells hamper immune response to HIV

Recent studies have shown that HIV causes a vigorous and prolonged immune response that eventually leads to the exhaustion of key immune system cells--CD4+ and CD8+ T-cells--that target HIV.

FA imaging, invented at U-M, measures metabolic stress in retina - serves as early warning of diabetes

A new vision screening device, already shown to give an early warning of eye disease, could give doctors and patients a head start on treating diabetes and its vision complications, a new study shows.

Discover of key patterns in gene packaging

Although every cell of our bodies contains the same genetic instructions, specific genes typically act only in specific cells at particular times. Other genes are "silenced" in a variety of ways. One mode of gene silencing depends upon the way DNA, the genetic material, is packed in the nucleus of cells.

Common genetic variations increase risk of life-long nicotine addiction for young smokers

Common genetic variations affecting nicotine receptors in the nervous system can significantly increase the chance that European Americans who begin smoking by age 17 will struggle with life-long nicotine addiction. Published July 11 in the open-access journal PLoS Genetics, this research - led by scientists at the University of Utah together with colleagues from the University of Wisconsin - highlights the importance of preventing early exposure to tobacco through public health policies.

Scientists reveal key elements in Malaria parasite's "sticky sack" adhesion strategy

Malaria is one of the most devastating diseases afflicting humanity. It infects and debilitates about 600 million people and kills up to three million people every year, mainly in the wet tropical regions of the world. Children and pregnant women are at particularly high risk.

Potential new way to prevent graft-versus-host disease

A new University of Michigan study in mice suggests that a drug recently approved to fight cancer tumors is also able to reduce the effects of graft-versus-host disease, a common and sometimes fatal complication for people who have had bone marrow transplants.

How alcohol impacts heart and stroke risk may differ for men and women

The volume of alcohol consumption may have a significantly different effect on heart and stroke risk in men and women, according to a study of Japanese people published in Stroke: Journal of the American Heart Association.

Novel approach shows potential to become an emergency treatment for heart attack patients

Researchers at The Children's Hospital of Philadelphia have manipulated cell activity that occurs during the interruption of blood flow to strongly protect heart tissue in animal studies. The finding has the potential to become an emergency treatment for heart attack patients, particularly since already existing drugs might be pressed into service to produce the protective effects.

Heat waves when in hospital

Deaths due to high temperatures occur so quickly that patients do not have time to be admitted to hospital. This is why prevention campaigns are necessary to try and reduce the negative effects of the heat on health. This is pointed out in new research undertaken at the Hospital Universitario Gregorio Maranon, Madrid.
