Researchers study functional similarity between zebrafish and humans to fight infections

Since the human response to infection is highly complex, research to understand how people fight infection is facilitated by studying how similar processes occur in simpler organisms. Zebrafish are becoming an important model for human disease, since they are easily handled, maintained and manipulated and many fundamental processes between zebrafish and humans are conserved.

How the human brain processes incoming sensory signals amidst background noise

The brain never sits idle. Whether we are awake or asleep, watch TV or close our eyes, waves of spontaneous nerve signals wash through our brains. Researchers at the Salk Institute for Biological Studies studying visual attention have discovered a novel mechanism that explains how incoming sensory signals make themselves heard amidst the constant background rumblings so they can be reliably processed and passed on.

NIH awards $2.5 million grant to University of Utah cardiologist

A pioneering model that a University of Utah cardiologist proposes as a cause of heart disease is the kind of creative thinking the National Institutes of Health (NIH) likes to see-and reward with one of its most prestigious honors, a $2.5 million 2009 Pioneer Award.

Rescuing immune system cells can reduce risk of prostate cancer

Immune therapies have been explored as a way to treat cancer after it develops. But a new study from the University of Michigan Comprehensive Cancer Center suggests that genetic risk of prostate cancer can be reduced by rescuing critical immune system cells.

Hormone leptin can regulate bone mass and suppress appetite

Contrary to the prevailing view, the hormone leptin, which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain, according to a recent study published in Cell by Yale School of Medicine researchers and colleagues at Columbia University. This new finding contradicts the view that leptin acts primarily in the hypothalamus.

DISC1 linked to proper development and migration of neurons in the brain

Scientists now have a better understanding of a perplexing gene that is associated with susceptibility for a wide spectrum of severely debilitating mental illnesses. Two independent research studies published by Cell Press in the September 24th issue of the journal Neuron provide fascinating insight into the molecular mechanisms that link disrupted-in-schizophrenia 1 (DISC1) with the proper development and migration of neurons in the hippocampus, a brain area involved in learning and memory and associated with the pathology of schizophrenia.

Hope for heterotopic ossificiation

A recent United States Army study found that excessive bone growth, also known as heterotopic ossificiation (HO), affects up to 70 percent of soldiers who are severely wounded during combat. A much smaller percentage of the civilian population also suffers from HO following trauma or invasive surgery. The excessive bone forms within muscles and other tissues causing severe pain, reduced mobility and even local paralysis if untreated.

TSPs can block cancer-triggering proto-oncogenes

A tiny bit of genetic material with no previously known function may hold the key to stopping the spread of cancer, researchers at Yale School of Medicine and Sichuan University in Chengdu, China report in two papers in the September 7-11 issue of Proceedings of the National Academy of Sciences.

NIH grants $2.5M for the study of physical forces on cell function

The National Institutes of Health today announced an award of $2.5 million to a team led by Boston University biomedical engineer Bela Suki that will study the role of physical forces on cell function, with the goal of understanding the possible roles of these forces in diseases like atherosclerosis, neuro-degenerative diseases, metabolic disorders, aging and cancer.

Genetic variation helps identify hepatitis C infected people, according to a study

Walter and Eliza Hall Institute researchers are part of an international team that has discovered a genetic variation that could identify those people infected with hepatitis C who are most likely to benefit from current treatments.

Researchers visualize vasculature within native liver cyst walls of human ADPKD patients

As part of an effort to develop effective medical therapies that block the progression of liver cyst growth in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), researchers at the University of Colorado Anschutz Medical Center have found that the liver cyst walls develop and maintain a vasculature as they grow out from the body of the liver and that factors released by epithelial cells that line the liver cyst wall lumen can drive the proliferation and development of vascular endothelial cells.

Lab-on-a-chip performs 1,000 chemical reactions at once

Flasks, beakers, and hot plates may soon be a thing of the past in medicinal chemistry labs. Instead of handling a few experiments on a benchtop, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results literally shrinking the lab down to the size of a thumbnail.

Twinkling nanostars improve optical imaging of tumors

Researchers at Purdue University have created magnetically responsive gold nanostars that may offer a new approach to biomedical imaging. The nanostars gyrate when exposed to a rotating magnetic field and can scatter light to produce a pulsating or "twinkling" effect. This twinkling allows them to stand out more clearly from noisy backgrounds such as those found in biological tissue. Alexander Wei, Ph.D., and Kenneth Ritchie, Ph.D., M.Sc., led the team that created the new gyromagnetic imaging method. The work appears in a paper published in the Journal of the American Chemical Society.
