Agents that alter blood levels of beta-amyloid protein in mouse models of Alzheimer’s disease represent a potential approach to treating the illness in humans that may be safer than the vaccine method of therapy, researchers report in a new study.

Beta-amyloid protein is a component of the amyloid plaques that accumulate in the brains of people with Alzheimer¡’s disease. Beta-amyloid is viewed by many researchers and clinicians as the underlying cause of the degeneration and demen

Meta-analysis shows medication treatment decreases risk of future substance abuse

An analysis of all available studies that examine the possible impact of stimulant treatment for attention-deficit hyperactivity disorder (ADHD) on future substance abuse supports the safety of stimulant treatment. Using a statistical technique called meta-analysis, the researchers from Massachusetts General Hospital (MGH) found that medication treatment for children with ADHD resulted in an almost two-f

When Viagra was introduced in 1999, the drug’s manufacturer warned of a number of visual side effects, including possible nerve damage to the eyes. But a UC Irvine College of Medicine study rules out some of these risks — even when the drug is taken in high doses.

According to Dr. Tim McCulley, assistant professor of ophthalmology, blood flow in the eye does not seem to be reduced by even high doses of the popular erectile dysfunction drug. Since Viagra lowers blood pressure overall,

Researchers at the Lawrence Livermore National Laboratory have discovered another fingerprint of human effects on global climate.

Recent research has shown that increases in the height of the tropopause over the past two decades are directly linked to ozone depletion and increased greenhouse gases.

The tropopause is the transition zone between the lowest layer of the atmosphere — the turbulently-mixed troposphere — and the more stable stratosphere. The tropopause lies rough

Significant reduction in severity and duration of cold symptoms

New research confirms the efficacy of zincum gluconicum nasal gel in reducing the severity and duration of common cold symptoms when treatment is started as late as the second day of illness. The study, which appears in the January issue of QJM: An International Journal of Medicine, was the first trial on the naturally acquired common cold to extend initiation of treatment beyond the first 24 hours of illness.

The department of entomology at Texas A&M University is abuzz with the news the honey bee genome is being sequenced by the Baylor College of Medicine Human Genome Sequencing Center, especially since Texas A&M helped that project take flight.

“This is a huge deal,” said Dr. Spencer Johnston, professor of entomology with the Texas Agricultural Experiment Station.

The honey bee was one of five species recently selected by the National Institutes of Health to have its genome sequenced
