‘Scrawny’ gene keeps stem cells healthy

Uncategorized No Comments »

pStem cells are the body’s primal cells, retaining the youthful ability to develop into more specialized types of cells over many cycles of cell division. How do they do it? Scientists at the Carnegie Institution have identified a gene, named “scrawny”, that appears to be a key factor in keeping a variety of stem cells in their undifferentiated state./p

Sleep Apnea, Stroke and Death Connection

8760 No Comments »

pObstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain’s ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society. The findings may help explain why people with sleep apnea are more likely to suffer strokes and to die in their sleep./p
