An adjuvant is a component of a vaccine that can help make it more effective by improving the immune response or causing the immune response to last longer. The goal of the new trial, RV460, is to evaluate whether an adjuvant can improve immune response to the antigens in the candidate vaccines. It will also help characterize the differences between the

Confirmed improvement in first responders' brain health after shortened training protocol

 E-Mail DALLAS (January 26, 2021) - Many people believe that they can t change their brains, or that their brain health will inevitably decline as they age. But the Strategic Memory Advanced Reasoning Tactics (SMART) training protocol, created by researchers and clinicians at the Center for BrainHealth®, has been demonstrated over the past two decades to improve cognitive function and psychological well-being in laboratory participants. Recent research suggests that SMART can even make long-lasting improvements to people s brain health when given outside of the lab in short, informal training sessions. A paper detailing these findings was recently published in Military Medicine. The research was a collaboration between Leanne R. Young, PhD, of Applied Research Associates, Inc. and researchers from the Center for BrainHealth, led by Sandra Bond Chapman, PhD, founder and chief director, and Jennifer Zientz, MS, CCC/SLP, head of clinical services.

Sound waves spin droplets to concentrate, separate nanoparticles

The technique is much more efficient than traditional centrifuge approaches, working its magic in under a minute instead of taking hours or days, and requires only a tiny fraction of the typical sample size. The invention could underline new approaches to applications ranging from precision bioassays to cancer diagnosis.
