Differential Neutralization Profiles of 17DD Vaccinated Population to 17D-204 and 17DD Vaccine Strains.

: Yellow fever virus (YFV) (, ) is the etiologic agent of yellow fever (YF), a vector-borne disease with significant morbidity and mortality across the tropics and neotropics, despite having a highly efficacious and safe vaccine (17D). Vaccination provides lifelong protection from YF disease mediated by humoral immunity. There are several versions of the original 17D vaccine: 17D-204 (marketed in the USA as YF-VAX, in France as Stamaril, and in China as Tiantan-V), 17D-213 (Russian Federation), and 17DD (by FIOCRUZ in Brazil).

P2X7 receptors modulate acquisition of cue fear extinction and contextual background memory generalization in male mice.

The purinergic P2X7 receptors (P2X7R) are activated by adenosine triphosphate (ATP) in several brain regions, particularly those involved with emotional control and the regulation of fear-related memories. Here, we investigate the role of P2X7R in fear learning memory, specifically in the acquisition and consolidation phases of the cued fear conditioning paradigm. C57Bl/6 wildtype (WT) male mice that received a single i.

ADHD Assessment and Treatment Services in a Sample of U.S. Colleges and Universities.

Objective: Up to 2 million college students in the United States have been diagnosed as having attention-deficit hyperactivity disorder (ADHD), a condition associated with negative academic, social, and psychiatric outcomes. The authors investigated the online availability and content of policies governing ADHD services at college clinics.

Methods: Using a stratified sample of 200 colleges and universities, the authors reviewed clinic websites and invited clinical staff to participate in a survey.
