Resveratrol effective in lowering amyloid-beta peptides

A study published in the November 11 issue of the Journal of Biological Chemistry shows that resveratrol, a compound found in grapes and red wine, lowers the levels of the amyloid-beta peptides which cause the telltale senile plaques of Alzheimer's disease.

Association of aprotinin with reduced glucose levels during CABG surgery

An anesthesiology research team at Columbia University Medical Center have completed the first human study to show that aprotinin, a protease inhibitor, was associated with lower blood glucose levels during coronary artery bypass graft (CABG) surgery.

Research reveals possible mechanisms for the treatment of cocaine addiction

Researchers are now understanding in greater detail the molecular machinery underlying the short-term brain changes that produce the high of cocaine, as well as the longer-term changes behind addiction. Their findings offer hope for targeted drugs that can short-circuit that addiction machinery.

New approaches to counteract platelet shortages

Availability of safe platelets is a fundamental blood transfusion challenge and can be especially problematic in times of emergency. Several studies presented at the annual American Association of Blood Banks (AABB) meeting today demonstrate new approaches to counteract platelet shortages by enhancing the safety of whole blood derived platelets, precluding the need to rely on only those obtained through apheresis.

Immature stem cells that proliferate to form brain tissues in mice can function for at least a year

New studies in mice have shown that immature stem cells that proliferate to form brain tissues can function for at least a year -- most of the life span of a mouse -- and give rise to multiple types of neural cells, not just neurons.

Mechanism of X-chromosome dosage compensation in Drosophila

In Drosophila, like in humans, male cells have a single X chromosome, while female cells have two. Researchers have long debated over how X and autosomal chromosome gene expression is equalized between the sexes (generally regarding two different models, known as the activation model and the inverse model).

New Stat1 and interferon findings

By altering a molecule called Stat1, which is involved in cellular immune signaling, scientists have succeeded in making the molecule more responsive and thus more efficient. This old protein with a new twist may eventually be used to improve the body's defense against infection.

Clioquinol appears to block the genetic action of Huntington's disease

Clioquinol, an antibiotic that was banned for internal use in the United States in 1971 but is still used in topical applications, appears to block the genetic action of Huntington's disease in mice and in cell culture, according to a study reported by San Francisco VA Medical Center (SFVAMC) researchers.

Virginia Tech engineer investigates enzyme link to Huntington's, Parkinson's, and Alzheimer diseases

Several neurologically based afflictions, such as Huntington's, Parkinson's, and Alzheimer diseases, have been correlated to a higher than normal presence of a specific type of enzymes, called transglutaminases (TGase) in the human body.
