Researchers find protein associated with brain cell death

Neuroscientists at the Case Western Reserve University School of Medicine have found evidence of which protein in the brain's immune cells triggers a cascade of reactions that produces unregulated free radical production that eventually leads to the neural cell death found in Alzheimer's disease.

Pomegranate juice helps fight prostate cancer

Drinking an eight ounce glass of pomegranate juice daily increased by nearly four times the period during which PSA levels in men treated for prostate cancer remained stable, a three-year UCLA study has found.

Fish oil may help protect against age-related macular degeneration

A paper published in Trends in Neuroscience by Nicolas G. Bazan, MD, PhD of the Neuroscience Center of Excellence at LSU Health Sciences Center in New Orleans, reports on the role that the omega-3 fatty acids in fish oil play in protecting cells in the retina from degenerative diseases like retinitis pigmentosa and age-related macular degeneration.

Proteomics yields new drug targets for treating cardiogenic shock

When it comes to cell signaling and bioregulation, it's tough to find a more important molecule than nitric oxide (NO). Dysfunction of NO-mediated signaling is thought to be a culprit in lethal cardiovascular conditions such as angina, and septic, cardiogenic and hemorrhagic shock; it may play a role in many other illnesses as well.
