Researchers uncover key interaction in cholesterol regulation

Researchers at UT Southwestern Medical Center have determined the specific way in which a destructive protein binds to and interferes with a molecule that removes low-density lipoproteins (LDL), the so-called "bad" cholesterol, from the blood.

Gene expression in meningiomas may vary by hormone receptor status

An association between hormones and meningioma has long been postulated, but the specific nature of this relationship has remained unclear.

New discovery, immune cells confront viruses just inside of the lymph node

Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them. An improved understanding of how the immune system operates during a viral infection is critical to designing successful anti-virus vaccines.

Less waste in the synthesis of anti-inflammatory drugs

Dr Francesca Paradisi of the Centre for Synthesis and Chemical Biology (CSCB) at University College Dublin, and Professor Daria Giacomini and co-workers at the University of Bologna, Italy, have developed a highly efficient enzyme-driven process which could be applied to the synthesis of drugs such as Ibuprofen, avoiding the 50% waste of the undesired byproduct generated by current processes.

New Parkinson's disease research points to serotonin

For most people with Parkinson's disease, the only relief from the tremors, rigidity and impaired movement associated with the progressive loss of their motor skills is a drug called L-DOPA. But as the disease progresses, L-DOPA can cause prominent side effects that counteract its effectiveness.

Video games activate reward regions of brain in men more than women

Allan Reiss, MD, and his colleagues have a pretty good idea why your husband or boyfriend can't put down the Halo 3. In a first-of-its-kind imaging study, the Stanford University School of Medicine researchers have shown that the part of the brain that generates rewarding feelings is more activated in men than women during video-game play.

Isocitric acid from fermentation of sunflower oil - a new building block for pharma?

The citric acid cycle, one of the most important metabolic processes in our bodies, was formulated in 1937. Since then, all of the intermediates have been produced in multigram quantities - with one exception, (2 R,3S)-isocitric acid.

New research shows that people with blue eyes have a single, common ancestor

A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today.

Protein, macrophage migration inhibitory factor predicts heart attack response and cardiac damage

A protein has been found that influences the response of the heart to a lack of oxygen and blood flow, such as occurs during a heart attack, a team of Yale School of Medicine researchers report in Nature.

Neurogenesis plays an important role in the acquisition and storage of spatial memory

Boosted by physical and mental exercise, neural stem cells continue to sprout new neurons throughout life, but the exact function of these newcomers has been the topic of much debate.

Porous structures help boost integration of host tissue with implants

Results published in FASEB (the journal of the Federation of American Societies for Experimental Biology) by researchers at Columbia University, including Jeremy Mao of the Columbia College of Dental Medicine, demonstrate a novel way of using porous structures as a drug-delivery vehicle that can help boost the integration of host tissue with surgically implanted titanium.

New research allays some panic about suspected cancer-causing agents

New research has allayed some panic about suspected cancer-causing agents, such as deodorants, coffee and artificial sweeteners. A risk assessment tool has been developed through the Cancer Control Program at South Eastern Sydney & Illawarra Health (SESIH) by a University of New South Wales (UNSW) researcher, Professor Bernard Stewart.
