Lack of vitamin D2 associated with Alzheimer's

Scientists at London's Kingston University have uncovered evidence that lack of a particular form of vitamin D is associated with Alzheimer's disease.

Corneal limbal stromal cells could lead to new treatments for eye conditions

Eye experts and scientists at the University of Southampton have discovered specific cells in the eye which could lead to a new procedure to treat and cure blinding eye conditions.

Low antioxidant levels contribute to increased blood pressure during exercise for people with PAD

Low antioxidant levels contribute to increased blood pressure during exercise for people with peripheral arterial disease, according to researchers at Penn State Hershey Heart and Vascular Institute.

Better understanding of clotting dynamics in atherosclerosis could lead to more effective drugs

The disease atherosclerosis involves the build up of fatty tissue within arterial walls, creating unstable structures known as plaques. These plaques grow until they burst, rupturing the wall and causing the formation of a blood clot within the artery. These clots also grow until they block blood flow; in the case of the coronary artery, this can cause a heart attack.

Study on genetic capacity of diverse populations to make critical PUFAs

World-renowned scientists are taking what they've learned from their multicenter research collaboration studying the health impact of fatty acids on diverse populations to set up a genetics center in India.

Early clues regarding progression of Alzheimer's disease found in brain's metabolism

When it comes to Alzheimer's disease, scientists usually - and understandably - look to the brain as their first center of attention. Now researchers at Tel Aviv University say that early clues regarding the progression of the disease can be found in the brain's metabolism.

New understanding of how noise can break critical tip link protein structure in inner ear cells

Researchers have mapped the precise 3-D atomic structure of a thin protein filament critical for cells in the inner ear and calculated the force necessary to pull it apart.

Autologous stem cells do not improve heart function when given three weeks after heart attack

Administering stem cells derived from patients' own bone marrow either three or seven days after a heart attack is safe but does not improve heart function six months later, according to a clinical trial supported by the National Institutes of Health (NIH).

ACS Prized Science video features advances in personalized medicine

Personalized medicine - the promise of customizing treatments that will work best for each individual patient - could get a boost from advances in understanding how the proteins that help determine health and disease take the three-dimensional shapes needed to work in the body. That's the message of the latest episode of the 2012 edition of a popular video series from the American Chemical Society (ACS), the world's largest scientific society.

Researchers simulate activity of cultured neural networks

After a short period of growth, cultured networks of neurons regularly exhibit major activity in the absence of external stimulation. These "bursts" are entirely related to growth. At this stage, they have little to do with learning behaviour, as the network is still too young to sustain a process of memory formation. This has now for the first time been simulated for networks ranging in size from 10,000 to 50,000 neurons. The simulations provide insight into the role of the growth process in initial activity.

Two new EU Member States now represented within TRANSVAC services platform

In addition to the initial panel of nine services, the TRANSVAC transnational access platform has integrated in July 2012 five additional groups which provide their services to users on a free and paid basis. Two new European Union (EU) Member States are now represented within the platform of services: France and Portugal.

Studies provide first clues of balanced de novo chromosomal rearrangements

Whole genome sequencing of the DNA code of three prenatal samples provided a detailed map of the locations of their chromosomal abnormalities in 14 days, scientists reported today at the American Society of Human Genetics (ASHG) 2012 meeting in San Francisco.

Scientists develop measures to prevent health problems associated with biogenic amines in wine

Biogenic amines may be one of the factors responsible for symptoms such as headaches, gastro-intestinal disorders, shortness of breath, fall in blood pressure, and even unconsciousness and cardiac arrhythmia in severe cases. Histamine, one of the best known members of this group, can cause serious physical problems. Biogenic amines can be produced in the body by natural metabolic activities but are also ingested in larger quantities with food.
