Imagine a battlefield medic or emergency medical technician providing first aid with a special wad of cottony glass fibers that simultaneously slows bleeding, fights bacteria (and other sources of infection), stimulates the body's natural healing mechanisms, resists scarring, and—because it is quickly absorbed by surrounding tissue — may never have to be removed in follow-up care. Or, imagine diabetics with hard-to-heal wounds finding a source of relief from the battle against infections and limb amputation.

A gene therapy approach using a protein called CD59, or protectin, shows promise in slowing the signs of age-related macular degeneration (AMD), according to a new in vivo study by researchers at Tufts University School of Medicine.

Researchers have proven that melatonin –a natural hormone produced by the body– helps in controlling weight gain –even without reducing the intake of food–, improves blood lipid profile –as it reduces triglicerids–, increases HDL cholesterol and reduces LDL cholesterol.

Stronger and tougher body armor to shield the chest, abdomen and back may be just what soldiers fighting in the Afghanistan and Iraq wars need to better protect their brains from mild injuries tied to so-called “shell shock,” results of a Johns Hopkins study in mice suggests.

Cotinine, a compound derived from tobacco, reduced plaques associated with dementia and prevented memory loss in a mouse model of Alzheimer’s disease, a study led by researchers at Bay Pines VA Healthcare System and the University of South Florida found.

A new study in rats is shedding light on how sleep-deprived lifestyles might impair functioning without people realizing it. The more rats are sleep-deprived, the more some of their neurons take catnaps — with consequent declines in task performance.

Gene therapy that uses a tiny benign virus to take a gene to the rods and cones of the eye's retina (the light-sensing organ) prevented blindness in mice with a genetic blinding syndrome, said researchers from Baylor College of Medicine in an online report of the Proceedings of the National Academy of Sciences.

In the first animal model of Amyotrophic Lateral Sclerosis (ALS), developed by Dr. Udai Pandey, Assistant Professor of Genetics at LSU Health Sciences Center New Orleans, Dr. Pandey's lab has found in fruit flies that blocking the abnormal movement of a protein made by a mutated gene called FUS also blocks the disease process.

It's a conflict with no resolution in sight. On one side, scientists who experiment on animals. On the other, animal rights activists who believe that no animal should ever be harmed. But how far can activists go before their right to free speech threatens the scientists and their work?

An experimental drug that blocks two points of a crucial cancer cell signaling pathway inhibits the growth of ovarian cancer cells and significantly increases survival in an ovarian cancer mouse model, a study at UCLA's Jonsson Comprehensive Cancer Center has found.

Chronic inhalation of polluted air appears to activate a protein that triggers the release of white blood cells, setting off events that lead to widespread inflammation, according to new research in an animal model.

Adult mice engineered to have more newborn neurons in their brain memory hub excelled at accurately discriminating between similar experiences — an ability that declines with normal aging and in some anxiety disorders. Boosting such neurogenesis in the adult hippocampus also produced antidepressant-like effects when combined with exercise, in the study funded by the National Institutes of Health.

Researchers at North Carolina State University are narrowing the search for genes involved in non-Hodgkin lymphoma – by turning dogs into humans. Humans and dogs don’t just share companionship and living space, they also share a similar genetic makeup. Additionally, they share the same types of cancer, including lymphoma.
