Study in mice suggests molecules in plants have beneficial effect on Alzheimer's disease
A set of molecules found in certain plants appears to have a beneficial effect in brain tissue associated with Alzheimer's disease, according to a new study conducted in mice. The study was led by researchers at the University of South Florida and Cedars-Sinai Medical Center. An article in the Journal of Cellular and Molecular Medicine is... view more... (2008-05-07)
Beta-carotene assoc. with higher risk of some cancers in women smokers but not nonsmokers
A new study of French women has found that high beta-carotene intake-through a combination of diet or supplementation-is associated with a higher risk of tobacco-related cancers in smokers, but the risk of these cancers decreases with increasing beta-carotene intake in nonsmokers. view more (2005-09-21)
New cause of critical illness hypeglycemia identified
The endocrinologic basis of pediatric critical illness hypergylcemia (CIH) differs depending on the disease processes. Researchers writing in BioMed Central's open access journal Critical Care describe how both peripheral insulin resistance and primary beta-cell dysfunction can cause CIH in children. view more (2009-02-26)
Epilepsy drug may help Alzheimer's patients
A popular epilepsy drug may also be beneficial in patients with Alzheimer's disease (AD), according to a new study to be published on October 27 in the Journal of Experimental Medicine. The anti-seizure drug valproic acid improved memory and reduced brain lesions in mice with an AD-like disease. view more (2008-10-27)
Battling Diabetes with Beta Cells
Affecting eight percent of America's population, diabetes can lead to blindness, kidney failure, strokes and heart disease. Thanks to Tel Aviv University researchers, a new cure -- based on advances in cell therapy -- may be within reach. view more (2008-09-03)
Human beta cells can be easily induced to replicate, according to study in Diabetes
Researchers at the University of Pittsburgh School of Medicine have successfully induced human insulin-producing cells, known as beta cells, to replicate robustly in a living animal, as well as in the lab. view more (2009-01-14)
Scientists remove amyloid plaques from brains of live animals with Alzheimer's disease
A breakthrough discovery by scientists from the Mayo Clinic in Jacksonville, FL, may lead to a new treatment for Alzheimer's Disease that actually removes amyloid plaques-considered a hallmark of the disease-from patients' brains. view more (2009-10-15)
The Definitive Beta-blocker For Heart Failure? (pp 2, 7, 14)
Results of a European study in this week's issue of THE LANCET suggest that the beta-blocker carvedilol offers substantial survival benefit compared with another widely-used beta blocker for the treatment of chronic heart failure. Beta blockers reduce death in patients who are also taking diuretics and ACE inhibitors for chronic heart failure. In... view more... (2003-07-02)
Compounds that trigger beta cell replication identified by JDRF funded researchers
Researchers at the Genomics Institute of the Novartis Research Foundation (GNF) have identified a set of compounds that can trigger the proliferation of insulin-producing cells in the pancreas, using sophisticated high-throughput screening techniques. view more (2009-02-26)
Further evidence showing treatment benefits of beta interferon for multiple sclerosis (pp 1463, 1489)
Results of a European study in this week's issue of THE LANCET provide further evidence that patients with early symptoms of multiple sclerosis given a weekly injection with interferon beta are less likely to progress to full clinical disease after two years follow-up. The study showed that the drug reduced patients' loss of brain tissue compared... view more... (2004-10-20)
Atrial fibrillation linked to increased hospitalization in heart failure patients
Patients with atrial fibrillation, common in those with advanced chronic heart failure, have an increased risk of hospitalization due to heart failure. view more (2009-07-07)
An atomic-level look at an HIV accomplice
Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity. view more (2009-11-20)
Impaired clearance of amyloid-beta causes vascular damage in Alzheimer's disease
New research suggests that accumulation of amyloid-β peptides in cerebral blood vessels, as opposed to the brain itself, may be a more important pathological mediator of Alzheimer's disease. view more (2005-07-21)
Vaccine thwarts the tangles of Alzheimer's
A new study by NYU Medical Center researchers shows for the first time that the immune system can combat the pathological form of tau protein, a key protein implicated in Alzheimer's disease. view more (2007-08-22)
Effective Alzheimer treatment: The nose knows
Alzheimer disease (AD) is the most common form of senile dementia, with no effective treatment available. In a study appearing online on August 11 in advance of print publication of the September 1 issue of the Journal of Clinical Investigation. view more (2005-08-12)
Prion disease infectivity causes heart damage in mouse study
Laboratory mice infected with the agent of scrapie—a brain-wasting disease of sheep—show high levels of the scrapie agent in their heart several hundred days after being infected in the brain, indicating that heart infection might be a new aspect of this disease. view more (2006-07-07)
Scientists use Iceland's genealogical database to pinpoint the heritage of a deadly disease
A collaboration of scientists from Iceland and the United States has used Iceland's genealogical database* to trace the ancestors of patients suffering from hereditary cystatin C amyloid angiopathy (HCCAA). Analysis shows that the deadly mutation in the cystatin C gene, L68Q, derives from a common ancestor born roughly 18 generations ago, around... view more... (2008-06-20)
Joslin researchers uncover potential role of leptin in diabetes
A new Joslin-led study has shown that leptin, a hormone known mainly for regulating appetite control and energy metabolism, plays a major role in islet cell growth and insulin secretion. view more (2007-10-02)
Advance towards early Alzheimer's diagnosis
An Australian research project has found a way to bring forward the detection of early stage Alzheimer's disease by up to 18 months. view more (2008-06-18)
New target for heart failure therapy identified
A novel signaling pathway plays a significant role in the production of aldosterone, a hormone that promotes heart failure after a myocardial infarction, according to a study conducted by Thomas Jefferson University researchers. view more (2009-03-17)
