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

What are rods and rings?

This image of mouse embryonic fibroblasts comes from Cara Schiavon, a graduate student in Rick Kahn’s lab in the Department of Biochemistry. It was impressive enough to capture interest from Emory Medicine‘s graphics designer Peta Westmaas. The light green shapes are “Rods and Rings,” structures that were identified just a few years ago by scientists studying how cells respond to antiviral drugs, such as those used against hepatitis C.

The rod and ring structures appear to contain enzymes that cells use for synthesizing DNA building blocks. Patients treated with some antiviral drugs develop antibodies against these enzymes.

The turquoise color represents microtubules, components of cells’ internal skeletons. The orange color shows DNA within nuclei. The spots in the nuclei are areas where DNA is more compact. The overall image is a “z-stack projection” acquired using the Olympus FV1000 confocal microscope in Emory’s Integrated Cellular Imaging Core.
