Why women are more susceptible to anterior cruciate ligament (ACL) injuries

New research presented today at the 72nd Annual Meeting of the American Academy of Orthopaedic Surgeons includes important findings on the causes of anterior cruciate ligament (ACL) injuries in female athletes, such as posture and body movement. These findings may be key in the effort to find ways to prevent these types of injuries.

Scientists identify immune-system mutation

A team of Fox Chase Cancer Center scientists led by immunologist Dietmar J. Kappes, Ph.D., has identified the genetic mutation that keeps a mouse strain from developing white blood cells, or lymphocytes, called helper T cells. The report by Kappes and his colleagues appears in the Feb. 24 issue of Nature.

Dental therapy that regenerates the tooth enamel rather than drilling

Unlike skins or bones, the tooth enamel, which forms the hard surface of a tooth, does not regenerate itself once damaged. Therefore, the conventional dental treatment includes drilling of the decayed part of a tooth and filling the hole with resin or metal alloy dental materials.

Should screening for sleep apnea be required for all men?

According to a new study, men in their 20s need to be screened the most. That's because men aged 20 to 29 with severe sleep apnea have 10 times the risk of dying from heart related ailments than their non sleep apnea peers in the general population, and a much higher risk than older men with sleep apnea.

New imaging method that may provide a clearer diagnosis of breast cancer

"This technique involves a new method for interpreting information gathered through MRI," explained Springer. "The technique involves recognizing that certain properties of MRI signals can change during the examination, much like the changing of a camera's shutter speed.

Scientists have regenerated a damaged optic nerve

This achievement, which occurred in laboratory mice and is described in the March 1, 2005 issue of the Journal of Cell Science, holds great promise for victims of diseases that destroy the optic nerve, and for sufferers of central nervous system injuries.

Protein called CK2 plays a deadly role in colorectal carcinoma

A protein called CK2 plays a deadly role in colorectal carcinoma by blocking the ability of these tumors to activate a natural self-destruct mechanism that would clear this cancer from the body. This finding, by researchers at St. Jude Children's Research Hospital, is currently published in the online edition of Oncogene.

Is it exercise or dieting that helps prevent cancer?

Scientists and health professionals have long believed that maintaining a healthy - or "ideal" - weight makes a difference in decreasing an individual's risk for cancer. But one lingering question is whether or not it's better, in terms of cancer prevention, if that weight is reached and maintained by dieting or by exercising.

Scientists have replicated hepatitis C virus (HCV) in the laboratory

For the first time, scientists have replicated hepatitis C virus (HCV) in the laboratory. The ability to replicate HCV in cell culture will allow researchers to better study the life cycle and biology of this virus and to test potential antiviral compounds, which may lead to new therapies for the liver disease that results from infection with HCV.
