Benralizumab for eosinophilic gastritis: a single-site, randomised, double-blind, placebo-controlled, phase 2 trial.

Background: In eosinophilic gastrointestinal diseases, the role of eosinophils in disease pathogenesis and the effect of eosinophil depletion on patient outcomes are unclear. Benralizumab, an eosinophil-depleting monoclonal antibody that targets the interleukin-5 receptor α, might eliminate gastric tissue eosinophils and improve outcomes in eosinophilic gastritis. We aimed to assess the efficacy and safety of benralizumab in patients with eosinophilic gastritis.

Prevalence of Diagnosed and Undiagnosed Hepatitis C in a Midwestern Urban Emergency Department.

Background: Targeted hepatitis C virus (HCV) screening is recommended. Implementation of screening in emergency department (ED) settings is challenging and controversial. Understanding HCV epidemiology in EDs could motivate and guide screening efforts.

Sex differences in methamphetamine-evoked striatal dopamine of mice are reversed by nomifensine.

Male mice show more severe striatal dopamine depletions to the psychostimulant, methamphetamine (MA). To gain some understanding for this sex difference, we examined MA-evoked dopamine (DA) responses from superfused striatal tissue fragments of male and female mice under conditions of a dopamine transporter which was either unaltered (Experiment 1) or inhibited, with use of the drug, nomifensine (Experiment 2). In Experiment 1, MA-evoked DA was significantly greater in male versus female mice.

Testosterone modulation of striatal dopamine output in orchidectomized mice.

Three experiments are presented in which dopamine (DA) responses from superfused striatal tissue of orchidectomized (ORCH) mice treated or not with testosterone (T) are compared. In experiment 1, potassium-stimulated DA output was significantly greater in ORCH vs. ORCH+T mice.
