Oversight of Right-to-Try and Expanded Access Requests for Off-Trial Access to Investigational Drugs.

For decades, the U.S. Food and Drug Administration (FDA) has provided an "expanded access" pathway that allows patients who meet qualifying conditions to gain access outside a clinical trial to an investigational medical product being tested to see if it is safe and effective for a specific use.

Oxidative Stress Levels in the Brain Are Determined by Post-Mortem Interval and Ante-Mortem Vitamin C State but Not Alzheimer's Disease Status.

The current study highlighted several changes in measures of oxidative stress and antioxidant status that take place in the mouse brain over the course of 24 h post-mortem. Ascorbic acid (vitamin C) and glutathione both decreased significantly in cortex in as little as 2 h and malondialdehyde levels increased. Further change from baseline was observed up to 24 h, including carbonyl and sulfhydryl formation.
