Dietary nitrate ingested with and without pomegranate supplementation does not improve resistance exercise performance.

This study tested the hypothesis that co-ingesting nitrate (NO)-rich beetroot juice (BR) and pomegranate powder (POM) would enhance neuromuscular performance during vertical countermovement jumps, explosive kneeling countermovement push-ups, and back squats compared to BR ingestion alone. Fifteen recreationally-active males were assigned in a double-blind, randomized, crossover design, to supplement in 3 conditions: (1) NO-depleted beetroot juice (PL; 0.10 mmol NO) with two empty gelatin capsules; (2) NO-rich beetroot juice (BR; 11.

Improving pandemic preparedness through better, faster influenza vaccines.

. Timely availability of effective influenza vaccine will be critical to mitigate the next influenza pandemic. The mission of Biomedical Advanced Research and Development Authority (BARDA) is to develop medical countermeasures against pandemics, including influenza and other health security threats.

Tracking progress in universal influenza vaccine development.

Conventional influenza vaccines are designed to stimulate neutralizing antibodies against immunodominant but highly variable hemagglutinin antigens. Inherent limitations include suboptimal protection against rapidly changing seasonal influenza viruses and a lack of protection against antigenically novel pandemic influenza. New technologies for developing influenza vaccines that induce more broadly protective and durable immunity are a growing area of research and focus on a variety of approaches, including targeting conserved antigens and stimulating cross-reactive T cell responses.
