Study investigates value of "Center of Excellence" designation

A new study says cancer surgery performed at a medical center designated by the National Cancer Institute (NCI) as a "center of excellence" is associated with less risk of death soon after surgery than if performed at a high-volume surgery center, but finds no difference in five-year survival rates.

Course of injections in childhood might help protect people from heart disease later in life

A course of injections in childhood might help protect people from heart disease later in life. And for those whose arteries are already clogged up, a dose of antibodies could provide immediate benefits. That's the enticing vision raised by animal studies.

Spinal cord injury and obesity

Researchers at the University of Michigan Health System are looking at how people with spinal cord injury burn calories and how that is affected by their muscle mass and body weight. The goal is to make better recommendations to people with spinal cord injury, but the research will also translate into greater understanding of obesity in the general population as well.

Hirsute women most likely have androgen excess-related disorders, primarily polycystic ovary syndrome

Among women in their child-bearing years, even minimal amounts of unwanted hair in male-type patterns – especially in the presence of other subtle changes – may be a sign of a hormonal imbalance linked to a variety of serious side effects and medical conditions, according to the December 2004 issue of the American Journal of Obstetrics and Gynecology.

Needling chromosomes yields insights into cell division

By impaling individual chromosomes with glass needles one thousandth the diameter of a human hair, a Duke University graduate student has tested their "stickiness" to one another during cell division. Her uncanny surgical skills have added a piece to the large and intricate puzzle of how one cell divides into two -- a process fundamental to all organisms.

Somatic hypermutation (SHM) should prove to be extremely useful in directed protein evolution

Fascinated by the efficient way the human immune system generates a rapid response to create a near-infinite variety of antibodies, researchers have "hijacked" that machinery and used it to evolve a new type of fluorescent protein.
