Researchers have developed a nomogram specifically for women to predict their expected exercise capacity at any given age

Researchers have developed a nomogram (alignment chart) specifically for women that can be used to predict their expected exercise capacity at any given age, as well as demonstrated that the resulting measure is a predictor of the risk of death.

Containment of a Southeast Asian outbreak of avian influenza in humans may be possible

Though quick to caution about the many things that could go wrong, researchers say that it may be possible to contain a Southeast Asian outbreak of avian influenza in humans, buying precious time for the production of a vaccine.

Bone marrow-derived cells fail to meet high expectations says Bonn study

Adult stem cells taken from bone marrow are the "shooting stars" of their field. Many research scientists have been speculating that the cells might be able to pass through the blood into diseased organs and replace defective tissue. Such cells are seen as the potential key to the treatment of certain muscle diseases.

Scientist have found an unexpected effect of the interaction of PTEN and p53 genes in early stage prostate cancer

Prostate cancer, the second leading cause of cancer death for men in the United States, is caused by changes in several tummor suppressor genes including PTEN and p53. Up to 70 percent of men with prostate cancer have lost one copy of the PTEN gene at the time of diagnosis, and p53 is absent in a high number of patients with advanced prostate cancer.

Obesity's effects on mortality may have been over-estimated

New research shows that obese adults who reach the age of 70 are at no greater risk of dying than their non-obese counterparts, but they do have a much greater probability of spending their remaining years disabled. The data supporting this is reported in the August 2005 issue of The Gerontologist (Vol. 45, No. 4).

First evidence that complex genetic interactions account for autism risk

Using a novel analysis of the interactions among related genes, Duke University Medical Center researchers have uncovered some of the first evidence that complex genetic interactions account for autism risk. The Duke team found that the brain mechanism that normally stops or slows nerve impulses contributes to the disease.
