Newly discovered molecular switch creates new path to study birth defects and cancer

Researchers have discovered a central molecular switch in fruit fly embryos that opens new avenues for studying the causes of birth defects and cancer in humans.

Low vitamin D levels substantially increase risk of death

Researchers at Johns Hopkins are reporting what is believed to be the most conclusive evidence to date that inadequate levels of vitamin D, obtained from milk, fortified cereals and exposure to sunlight, lead to substantially increased risk of death.

Designer RNA fights high cholesterol, medical researchers find

Small, specially designed bits of ribonucleic acid (RNA) can interfere with cholesterol metabolism, reducing harmful cholesterol by two-thirds in pre-clinical tests, according to a new study by researchers at UT Southwestern Medical Center in collaboration with Alnylam Pharmaceuticals and the Massachusetts Institute of Technology.

Aspirin, acid-blocker a-day keeps GI bleeding at bay

For patients with clogged heart arteries who take long-term, low-dose aspirin to prevent a cardiac event, adding a stomach acid-blocking drug to their daily routine has been shown to reduce their risk for upper gastrointestinal bleeding - an infrequent, but serious side-effect of regular aspirin use.

Children with HIV in poor countries more adherent to treatment than children in rich countries

Researchers from the Indiana University School of Medicine, the Regenstrief Institute and Moi University School of Medicine are the first to report that adherence to antiretroviral therapy (ART) to fight human immunodeficiency virus (HIV) in children who live in low income countries is as high as or higher than adherence by children living in high income countries.

Technological crystal ball boosts AIDS survival

A cure for the virus that causes AIDS may still be beyond our grasp, but European researchers have developed a predictive software system for HIV that could help extend the lives of victims of the killer disease.

Therapies which boost the clearance of faulty proteins in cells may slow down ageing

Scientists say as people age, their cells become less efficient at getting rid of damaged protein and the result is a buildup of toxic material; this is particularly apparent in Alzheimer's, Parkinson's disease and other neurodegenerative disorders associated with ageing.

Dopamine and Parkinson's

Parkinson's disease and drug addiction are polar opposite diseases, but both depend upon dopamine in the brain. Parkinson's patients don't have enough of it; drug addicts get too much of it. Although the importance of dopamine in these disorders has been well known, the way it works has been a mystery.

RNAi used to dramatically suppress HIV infection in an organism

Hopes languished last September when a promising candidate HIV vaccine failed to work. Despite this setback, many researchers still believe immunization is possible, and a new study suggests they're correct-at least at the cellular level.

Scientists stop age-related decline in an entire organ

As people age, their cells become less efficient at getting rid of damaged protein - resulting in a buildup of toxic material that is especially pronounced in Alzheimer's, Parkinson's disease, and other neurodegenerative disorders.

Research finds a role for the GABA neurotransmitter in maintaining energy balance

Controlling body weight is a complicated process, as any frustrated dieter might attest. But as scientists continue to investigate the brain's intricate neurocircuitry and its role in maintaining energy balance, they are forming a clearer picture of the myriad events that lead to weight gain and weight loss.
