Ascorbic acid doesn't seem to help physical exercise performance

Orange juice or other sources of vitamin C (ascorbic acid), may (or may not) benefit you in terms of health and exercise, but contrary to what many people thought previously, ascorbic acid doesn't seem to help physical exercise performance.

Now significantly easier to search long stretches of DNA for genetic changes associated with disease

The researchers developed a method called direct genomic selection that accelerates the transition between family or population-based studies of disease inheritance patterns and identification of genetic variations that may contribute to disease.

Protein discovery with medical implications

It was a transforming moment. Researchers could barely believe their eyes. A molecular blob of a protein reshaped itself into a molecular Pacman in order to free new viruses from the inside of a bacterial cell.

Researchers want to see physicians reevaluate the drugs their elderly patients take to determine if they are appropriate

Just as our bodies physically slow down as we age, changes occur in the way that older bodies handle pharmaceuticals, and prescribing physicians need to be aware of those medications inappropriate for the elderly.

Discovery could lead to a screening test that identifies people who have a higher or lower susceptibility to HIV/AIDS

People with more copies of a gene that helps to fight HIV are less likely to become infected with the virus or to develop AIDS than those of the same geographical ancestry, such as European Americans, who have fewer copies of the gene, according to a study funded by the National Institute of Allergy and Infectious Diseases (NIAID).

Single abnormal cell can duplicate to form cancerous tumors

Researchers at the University of Pittsburgh have identified how a single aberrant cell can duplicate to form cancerous tumors, suggesting a specific protein mechanism as a target for the treatment of cancer, they report in a paper titled "Spindle Multipolarity Is Prevented by Centrosomal Clustering," published in the Jan. 7 issue of Science.

Adults with pre-diabetes can lose up to 3 percent of their body weight using diet

Adults with pre-diabetes can lose up to 3 percent of their body weight using diet, exercise and behavioral strategies, according to a systematic review of studies that analyzed weight-loss strategies for pre-diabetics.

Mutated gene may provide better idea of how cancer develops and progresses

Scientists are taking the first steps to find out how a gene that is mutated in many cancer cells functions in healthy cells.

Processes shed light on how DNA recombination mechanisms are related

Peter W. Atkinson, a University of California, Riverside professor of entomology and member of the university’s Institute for Integrative Genome Biology, is part of a team that has linked the movement of small pieces of DNA, known as transposable elements, to a process called V(D)J recombination that produces the genetic diversity responsible for the production of antibodies.

Gene sequencing explains why natural bioremediation 'bug' has big appetite for chlorinated pollutants

"The born-to-dechlorinate bug" is what Cornell University researchers called Dehalococcoides ethenogenes Strain 195 when they found the bacterium obligingly detoxifying the pollutant PCE, or perchloroethylene (a chlorinated solvent used for dry cleaning), in sludge from an Ithaca, N.Y., sewage treatment plant.

DermaVir, a novel treatment for HIV/AIDS, complements and improves present drug therapies

DermaVir, a novel treatment for HIV/AIDS, offers a new option which complements and improves present drug therapies. The vaccine, applied topically to the skin, has demonstrated efficacy in boosting immune responses and controlling virus replication in chronically infected monkeys.

Scents and emotions linked by learning

Whether emotional responses to scent are a product of nature or nurture is a matter of scientific debate. But a Brown University study, published in the current issue of the International Journal of Comparative Psychology, comes down on the nurturing side.

Reduced progression of atherosclerosis tied to statin drugs lowering fats, protein

Aggressive therapy with statins -- drugs that inhibit cholesterol synthesis -- works better than moderate statin therapy in reducing fats and proteins in the blood that have been linked to atherosclerosis, a new multi-center study concludes. Statins’ effects on both complex compounds appear beneficial in cutting patients’ cardiovascular risks.

Herpes virus is everywhere and it's unavoidable

While not the first, the researchers report that this study uses the most sensitive techniques in a cross-sectional assessment performed to date of the presence of HSV-1 DNA in the eyes and mouths of healthy individuals, in terms of population size and total samples collected.

In the first few days of each month, fatalities due to medication errors rise by as much as 25 percent above normal

Beware not the ides but the start of March – and April and May and every month. In the first few days of each month, fatalities due to medication errors rise by as much as 25 percent above normal, according to new research by University of California, San Diego sociologist David Phillips.

New insights into the strategies that the brain uses to measure time

From pouring a glass of milk to typing a news article, precise timing--down to the thousandth of a second--is key to the brain's control of movement.

Glia cells may be essential for the normal development of nerve cells responsible for hearing and balance

Traditionally viewed as supporting actors, cells known as glia may be essential for the normal development of nerve cells responsible for hearing and balance, according to new University of Utah research. The study is reported in the January 6, 2005 issue of Neuron and is co-authored by scientists at the University of Washington.

Antibiotics protect nerves in mice by turning on genes

A family of antibiotics that includes penicillin may help prevent nerve damage and death in a wide variety of neurological diseases, including Lou Gehrig's disease, dementia, stroke, and epilepsy, Johns Hopkins researchers have found.

States to explore putting restrictions on AIDS drug Trizivir

AIDS Healthcare Foundation (AHF) has sent a letter dated October 20, 2004, to the heads of all state Medicaid programs asking them put in use treatment authorization request (TAR) procedures on GlaxoSmithKline's (GSK) fixed-dose combination AIDS drug, Trizivir, as a standalone regimen for treatment naïve patients.
