Alzheimer's
NEW YORK -- Both being more physically active and adhering to a Mediterranean-type diet appears to be associated with reduced Alzheimer's risk, according to a new report in the August 12, 2009 issue of the Journal of the American Medical Association (JAMA).
Scientists have long suspected that Alzheimer's disease (AD) is caused by a small protein called the amyloid β-protein (Aβ). This protein clumps or binds to itself, eventually changing chemically to create brain protein deposits (plaques) that are characteristic of AD.
At least one strain of the H5N1 avian influenza virus leaves survivors at significantly increased risk for Parkinson's disease and possibly other neurological problems later in life, according to new research from St. Jude Children's Research Hospital.
Irvine, Calif. -- A UC Irvine study has found that a gene called TOMM40 appears twice as often in people with Alzheimer's disease than in those without it. Alzheimer's, for which there is no cure, is the leading cause of elderly dementia.
HOUSTON -- (Aug. 6, 2009) -- Rice University physicists have written the next chapter in an innovative approach for studying the forces that shape proteins -- the biochemical workhorses of all living things.
UCSF researchers have identified a new potential drug target for the herpes virus that causes Kaposi's sarcoma, re-opening the possibility of using the class of drugs called protease inhibitors against the full herpes family of viruses, which for 20 years has been deemed too difficult to attain.
New research has uncovered an early disruption in the process of memory formation in older humans who exhibit some early brain changes associated with Alzheimer's disease (AD) but show little or no memory impairment.
Athens, Ga. -- Most parts of living organisms come packaged with ribbons. The ribbons are proteins -- chains of amino acids that must fold into three-dimensional structures to work properly. But when for any reason the ribbons fold incorrectly, bad things can happen, and in humans misfolded-protein disorders include Alzheimer's and Parkinson's diseases.
Researchers have discovered that the enzyme, endothelin converting enzyme-2 (ECE-2), may cause the decrease in blood flow in the brain seen in Alzheimer's disease and contribute to progression of the disease.
A study led by Johns Hopkins and Utah State University researchers suggests that a particularly close relationship with caregivers may give people with Alzheimer's disease a marked edge over those without one in retaining mind and brain function over time.
Researchers at Yerkes National Primate Research Center, Emory University, contributed key comparative data for a landmark study showing African wild chimpanzees infected with simian immunodeficiency virus (SIV), an HIV-1-like virus, die prematurely and develop hallmarks of HIV-1 infection and AIDS.
July 22, 2009 -- (BRONX, NY) -- A cellular protein that may prevent nerve cells from dying also helps to improve insulin action and lower blood glucose levels, according to a study by researchers at Albert Einstein College of Medicine of Yeshiva University (http://www.aecom.yu.edu) in collaboration with scientists at Unive
Irvine, Calif. -- UC Irvine scientists have shown for the first time that neural stem cells can rescue memory in mice with advanced Alzheimer's disease, raising hopes of a potential treatment for the leading cause of elderly dementia that afflicts 5.3 million people in the U.S.
ST. PAUL, Minn. -- IVIg treatments, the addition of good antibodies into the blood stream, may hold promise for lowering the risk of Alzheimer's disease and other similar brain disorders, according to research published in the July 21, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.
Research carried out at the Hebrew University of Jerusalem has resulted in a promising approach to help treat Alzheimer's disease in a significant proportion of the population that suffers from a particularly rapid development of this disease.
