Doctors should encourage teens to limit their intake of food prepared away from home and to eat family dinners together

New research shows that adolescents who eat large amounts of fried food away from home are heavier and more likely to have a poor-quality diet.

Researchers have successfully combined computer modeling and experimental results in folding studies for small proteins

In unprecedented new research, scientists at Rice University have combined theory and experiment for the first time to both predict theoretically and verify experimentally the protein-folding dynamics of a large, complex protein.

Greasing the gears that drive the interferon signal

Interferon -- a critical protein that mediates the body's defense against a wide variety of infectious agents and tumors -- may soon have greater therapeutic value as the result of a new study by researchers at Washington University School of Medicine in St. Louis.

New insights that advance the current model of protein motility and muscle contraction

Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction.

Study shows that high-fat diets correlate to a chronic inflammatory state in the liver,

Mice that were fed diets high in fat and sugar developed immune system abnormalities in their livers, including reduced numbers of natural killer T (NKT) cells. These diet-related changes may contribute to obesity-related liver disease, according to a new study.

Potential beneficial effect of copper orotate

As one of the services for patients with Alzheimer's disease, the Department of Psychiatry at the Saarland University Medical Center offers participation in a clinical phase II trial. This clinical trial aims to elucidate a potential beneficial effect of copper orotate (an organic copper salt), which is given together with a standard cholinesterase inhibitor.

Sharper picture than previously available of major depressive disorder

Findings from the largest survey ever mounted on the co-occurrence of psychiatric disorders among U.S. adults afford a sharper picture than previously available of major depressive disorder (MDD) in specific population subgroups and of MDD's relationship to alcohol use disorders (AUDs) and other mental health conditions.

Scientists measure with unprecedented accuracy the strengths of hydrogen bonds in a protein

The scientists were then able to predict the function of different versions of the protein based on structural information, a novel outcome that was published recently in the Proceedings of the National Academy of Sciences.

Elimination of charges for health care at the point of use could have an immediate and substantial impact on child mortality

Abolishing user fees (charges for health care at the point of use) could prevent approximately 233,000 child deaths annually in 20 African countries, say researchers in this week's British Medical Journal.

First direct clues about how the brain alters the state of consciousness during sleep

In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain - regions that during waking hours are a bustling grid of neural dialogue - apparently lose their ability to communicate effectively, causing consciousness to fade.

Ubiquitin ligase Rnf6 may be involved in oncogenesis

In a recent study, Dr. Ingolf Bach and colleagues from the University of Massachusetts Medical School, Worcester and the University of Hamburg describe a novel role for the ubiquitin/proteosome protein degradation pathway in the regulation of local actin dynamics in neurons.

Healthy 3 and 4-year-olds drive flu epidemics

Current immunization policies recommend universal flu vaccination for children aged 6-23 months, but shots are advised for older children only if they have high-risk medical conditions.

Discovery of mechanism in the body that could lead to autoimmune diseases

Researchers at National Jewish Medical and Research Center have discovered a mechanism in the body that could lead to autoimmune diseases, such as lupus, rheumatoid arthritis, or diabetes.

Lab-made version of a human protein opens a new research avenue to better understand rheumatoid arthritis

A lab-made version of a human protein alleviates symptoms of both acute and chronic arthritis in mice and could be the basis for a new arthritis drug for people, report scientists from the National Institute of Allergy and Infectious Disease (NIAID), part of the National Institutes of Health (NIH).

Steroids significantly reduce heart damage in children with Kawasaki's disease

When added to standard treatment, steroids significantly reduce the odds of developing heart damage in children with Kawasaki's disease, according to a study in the October issue of Pediatrics. These findings address a gap in knowledge.

PSA doubling time is an important indicator of how well a patient will recover from prostate cancer

The clinical outcome for prostate cancer patients who have been treated with hormone therapy and radiation therapy can usually be determined by how rapidly their prostate specific antigen level rises following treatment

Training for health workers improves the quality of tuberculosis care and control without requiring extra staff

Tuberculosis is a growing problem in lower and middle income countries, including South Africa. The World Health Organization estimates that about two thirds of people with tuberculosis are never diagnosed and so cannot benefit from treatment, leaving the epidemic unchecked despite global treatment programmes.

Plant-derived compounds appear to block the activity of an enzyme that triggers inflammation in joints

The findings came to light while the researchers were studying the wildly different ways in which cells in human blood vessels and joints respond to pressure gradients generated from liquid moving along their surface, a force called shear stress.

Risk of acquiring HIV rises during pregnancy

The risk of acquiring HIV rises during pregnancy, according to a study of women in Uganda's Rakai District led by researchers at the Johns Hopkins Bloomberg School of Public Health. The increased risk for acquiring HIV remained even after researchers controlled for behavior and other factors that contribute to HIV risk.

Computer model shows biochemical variations, or noise, leads to oscillations in gene regulation that couldn't otherwise be predicted

Geneticists have debated for decades the relative importance of nature versus nurture in determining how an animal looks and behaves, and now University of California, San Diego (UCSD) scientists report that noise could also be an important factor in determining phenotype.
