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.

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.

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).

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.

Discovery establishes a role for the gene Rsf-1 in ovarian cancer

Johns Hopkins Kimmel Cancer Center researchers have linked alterations in a gene, called Rsf-1, to the most deadly ovarian cancers. The scientists say the discovery is the first to establish a role for the gene in ovarian cancer and may lead to a test that can predict, early on, which patients will develop aggressive disease.

New genes tied to lifespan extension

Drastically reducing calorie intake, or caloric restriction, is known to extend the lifespan of species including yeast, worms and rodents. Previous research linked a gene called Sir2 with lifespan extension due to caloric restriction, but worms and yeast that lack Sir2 also live longer when put on a tough diet, showing that some other genes must be at work.

Research may help create drugs to target the molecule-binding pathway, beneficial for treating arthritis and reducing inflammation

The first close-up look at a pro-inflammatory signaling molecule involved in immune response in mammals suggests that researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model, scientists say.

What works in preventing and reducing juvenile delinquency?

A new report released by the University of Wisconsin-Madison and the UW-Extension synthesizes the latest research on what works in preventing and reducing juvenile delinquency.

Nicotine has an unusual psychological property that may drive dependence

Associate Professor Athina Markou, Ph.D., who is in the Scripps Research Molecular and Integrative Neurosciences Department at Scripps Research’s La Jolla Campus, and Paul Kenny, Ph.D., a former Research Associate in her laboratory, report in an upcoming issue of the journal Neuropsychopharmacology that nicotine has an unusual psychological property that may drive dependence.

Researchers look at pharmacogenomics

When patients receive chemotherapy, 15 percent will have severe side effects while 85 percent will not - even though they're given the same relative dose.

Fever of unknown origin might be a marker of occult cancer

Fever of unknown origin is characterised by a fever of more than 3 weeks’ duration, temperatures of more than 38.3°C and a failure to identify the origin of the fever. Underlying causes of these fevers are difficult to diagnose, but proposed causes are infections, cancers and collagen-vascular diseases.
