Life Span :: Life span gap between US blacks and whites narrows

Prostate Cancer :: Soy found protective against localized prostate cancer

The largest study examining the relationship between the traditional soy-rich Japanese diet and development of prostate cancer in Japanese men has come to a seemingly contradictory conclusion: Intake of isoflavone chemicals, derived largely from soy foods, decreased the risk of localized prostate cancer but increased the risk of advanced prostate cancer.

Health Care :: Health care system for aging nerve cells

Uncontrolled neuronal death in the brain often gives rise to neurodegenerative illnesses like Parkinson or Alzheimer disease. Whether or not neurons have a long and healthy life is, apart from other factors, determined by the presence of neurotrophic factors. Scientists of the Max Planck Institute of Neurobiology have now provided unambiguous proof that the presence of the neurotrophic factor GDNF and its receptor Ret are essential for the survival of neurons in a specific brain region.
