Discovery of molecular pathway that detects and eliminates defective messenger RNAs from red blood cells

Other such pathways - known as surveillance pathways - operate in a more general way, in many cell types. Knowing how this specific surveillance system works can help researchers better understand hereditary diseases, in this case, thalassemia, a form of anemia, which is the most common genetic disorder worldwide.

Study shows pre-op red blood cell levels affect post-op outcomes

Men over 65 with even slightly abnormal red blood cell counts either too low or too high are at greater risk of post-operative death or car-diac events following a major non-cardiac surgery, according to a new study by researchers at the Providence Veterans Affairs Medical Center and The Warren Alpert Medical School of Brown University.

Outcome of surgery on the elderly could be affected by red blood cell count

Researchers in the United States have found that older patients about to undergo major surgery, who have either a high or low red blood cell count, are more at risk for heart attacks or even death following the operation.
