Researchers make headway in mystery of migraines

The research, published in the new issue of the Proceedings of National Academy of Sciences (PNAS), reveals how gene mutations known to cause a form of inherited migraine target a cellular process involved in brain cell communication.

Unravelling the Ebola virus’s biological cycle

Ebola virus infection in humans provokes a violent haemorrhagic fever. It usually flares up as intense epidemics. These kill 80 % of the people infected. Seven such outbreaks have hit Gabon and the Republic of Congo since 1994, leading to 445 cases resulting in 361 deaths.

Mathematical model describes the electrical storm that rages during a brain seizure

"We're trying to get to the underlying state of the brain that leads to these seizures," said Mark Kramer, a Ph.D. student in UC Berkeley's Applied Science and Technology Program and lead author of the paper. "Our hope is that the model can highlight potential areas where a seizure can be stopped."

Novel vaccine that uses immune cells as factories to produce Her2/neu protein may offer a way to treat some breast cancers

Based on successful animal studies, a novel vaccine that uses immune cells as factories to produce Her2/neu protein may offer a way to treat some human breast cancers, say researchers at The University of Texas M. D. Anderson Cancer Center.

Genomics tools provide clues to what causes 400 million cases of gastrointestinal disease each year

In a study that could benefit medical and food-safety research, scientists have used comparative genomics tools to find clues about why some strains of the bacterium Campylobacter – which each year cause more than 400 million cases of gastrointestinal disease – are more virulent than others.

Discovery shows how embryonic stem cells perform 'quality control' inspections

Biologists at the University of California, San Diego have found a fundamental mechanism used by embryonic stem cells to assure that genetically damaged stem cells do not divide and pass along the damage to daughter stem cells.

Amyloid growth can occur independently of oligomers

Improperly folded proteins are normally destroyed. But in a wide range of diseases, including prion (from proteinaceous and infectious) diseases and neurodegenerative diseases like Parkinson disease and Alzheimer disease, amyloid fibrils, or plaques--misshapen proteins that aggregate into characteristic ropelike configurations--accumulate in tissue.

Hair growing stem cells may one day provide treatments for human hair conditions

Researchers at the Howard Hughes Medical Institute at The Rockefeller University have isolated stem cells from the skin of a mouse, and showed, for the first time, that an individual stem cell can renew itself in the laboratory and then be used in grafts to produce skin, hair and oil glands.

Latest findings on HIV pathogenesis at AIDS Conference in Bangkok

At the XVth International AIDS Conference in Bangkok, Thailand, Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases and chief of the NIAID Laboratory of Immunoregulation (LIR), will present his laboratory’s latest findings on how aberrant immune activation underlies HIV pathogenesis.

Are we as crazy as mad cows?

When proteins in our body work properly, we can see, smell, consume and digest food, grow muscle and brain cells. But when these infinitely useful biological building blocks fail, the most pernicious diseases arise. Susan Lindquist has scrutinized the complex origami-like shapes of proteins and come to understand how structural mistakes can lead to a frightening class of neurodegenerative disorders, including “Mad Cow Disease.”

New Computer-Aided Approach Helps Doctors Tailor The Dosage of Abciximab

A computer-aided approach -- based on software-that-learns, promises to provide a new tool that helps doctors tailor the dosage of abciximab, a medicine frequently used before angioplasty to lessen the chance of heart attack.

New Theory About Alzheimer's Disease

A group of scientists at The Scripps Research Institute has proposed a new theory about the cause of Alzheimer's disease, the progressive neurodegenerative disorder that currently afflicts some 4.5 million Americans. According to the hypothesis, the disease arises as a consequence of inflammation, which creates abnormal metabolites out of normal brain molecules.
