Fermentation byproduct suppresses seizures in nerve agent poisoning

A compound found in trace amounts in alcoholic beverages is more effective at combating seizures in rats exposed to an organophosphate nerve agent than the current recommended treatment, according to new research published Read more

Post-anesthetic inertia in IH

A recent paper from neurologists Lynn Marie Trotti and Donald Bliwise, with anesthesiologist Paul Garcia, substantiates a phenomenon discussed anecdotally in the idiopathic hypersomnia (IH) community. Let’s call it “post-anesthetic inertia.” People with IH say that undergoing general anesthesia made their sleepiness or disrupted sleep-wake cycles worse, sometimes for days or weeks. This finding is intriguing because it points toward a trigger mechanism for IH. And it pushes anesthesiologists to take IH diagnoses into Read more

Aging, CVD risk factors and progenitor cells

Cardiologists Ibhar Al Mheid, Arshed Quyyumi and colleagues from Emory’s Clinical Cardiovascular Research Institute recently published a paper that weaves together insights from past research on circulating progenitor cells. They tease apart the influences of age and cardiovascular disease (CVD) risk factors on these cells, whose regenerative capacity has made them the target of much investigation. From this research, one can infer that the circulatory system has a limited regenerative capacity, and stress upon the system earlier in life depletes it later.

Circulating progenitor cells are rare cells in the blood that can become white or red blood cells, as well as endothelial cells, which line blood vessels and repair them when damaged by cardiovascular disease. Quyyumi and his colleagues have sought to deliver progenitor cells, derived from the patient’s own bone marrow, to the heart – or less invasively, spur them out of the bone marrow with drugs.
