Researchers at Wake Forest University Baptist Medical Center and the University of Pittsburgh report in the current Journal of Medical Genetics that they have found defects in the gene that produces a common protein in urine and that these defects are linked to two inherited kidney diseases.

For six years, the researchers had studied a family from Western North Carolina that has been plagued with a rare kidney disease, trying to learn more about the genetics of the disease. Anthony J. Bleye

Surgeons at University Hospitals of Cleveland have demonstrated that the risk of brain damage associated with the use of the heart lung machine can be significantly reduced by modifying the traditional placement of cannulas (tubing) for returning blood flow to the patient. The findings were presented last month at the American Heart Association’s annual Scientific Sessions conference in Chicago, Ill.

The neurological problems associated with bypass surgery have been widely reported. As

Four annual mass treatments of single doses of safe and inexpensive drugs found effective

Researchers report in the December 5 issue of the New England Journal of Medicine reaching an important milestone in learning how to halt a major mosquito-borne disease affecting 120 million people around the world. The disease, called lymphatic filariasis and commonly known as elephantiasis, is a leading cause of physical disfigurement, social ostracism, and economic loss throughout Africa, Asia

At this week’s First Pan American/Iberian Meeting on Acoustics in Cancun, researchers presented results on acoustic microscopy, a burgeoning technique that could provide new kinds of medically useful information on biological tissue. Unlike many other microscopy techniques, acoustical microscopy can be performed on living tissue and even inside the body, with the use of small ultrasound probes. And unlike optical microscopy of biological specimens, acoustic microscopy does not require tis sue stain

The internal state of an atom can change by absorbing or emitting bits of light. In a warm gas or plasma the electrons are frequently shuttling back and forth from one state to another. Some of these states are longer lived than others, though, because of extenuating circumstances. For instance, many transitions from an excited state to the ground state occur in nanoseconds, but some can last for tens of seconds or longer. Measuring the true lifetime of the longer-lived of these transitions is diff

Scientists at Emory University School of Medicine have identified a signaling pathway that is turned on when benign moles turn into early-stage malignant melanoma. The pathway could provide a new target for the diagnosis, prevention and treatment of the most lethal form of skin cancer. The research was reported in the December issue of the journal Clinical Cancer Research.

A team of Emory scientists led by Jack L. Arbiser, MD, PhD, found that the signaling pathway called mitogen activated p
