Curriculum Vitae Workshops: Promoting Transparency in Alpha Omega Alpha While Serving Student Needs.

Objective: To promote equity in the Alpha Omega Alpha Honor Medical Society (AOA) selection process, clear and timely communication of eligibility criteria is needed. Herein, the authors describe and assess the effectiveness of a novel method for improving transparency in the AOA selection process while also teaching students key professional development skills.

Methods: The authors hosted curriculum vitae (CV) workshops for interested medical students.

Gender and Nationality Trends in Manuscripts Published in Prominent Gastroenterology Journals Between 1997 and 2017.

Background: Gender disparities remain in the field of gastroenterology (GI) despite the decreasing gender gap in the medical field overall. We sought to examine primary and last female authorship as a marker of academic opportunity and advancement to assess the proportion of women publishing in GI over 20 years (1997-2017).

Methods: In this observational study, we assessed the gender and nationality of primary and last authors of original research manuscripts in three GI journals (Gastroenterology, Gut, and American Journal of Gastroenterology) across a 20-year period in 5-year intervals (in 1997, 2002, 2007, and 2012).

Reduced Esophageal Contractility Is Associated with Dysplasia Progression in Barrett's Esophagus: A Multicenter Cohort Study.

Background: The incidence of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) continues to rise, and risk stratification of patients with BE is needed. Impaired esophageal motility is associated with gastroesophageal reflux disease; however, whether esophageal dysmotility is a risk factor for dysplasia progression in BE is incompletely understood. This study aimed to characterize esophageal motility patterns in patients with BE and identify physiologic factors associated with dysplasia progression in BE.

Environmental or Nasal Cannula Supplemental Oxygen for Preterm Infants: A Randomized Cross-Over Trial.

Objective: To test the hypothesis that environmental compared with nasal cannula oxygen decreases episodes of intermittent hypoxemia (oxygen saturations <85% for ≥10 seconds) in preterm infants on supplemental oxygen by providing a more stable hypopharyngeal oxygen concentration.

Study Design: This was a single center randomized crossover trial with a 1:1 parallel allocation to order of testing. Preterm infants on supplemental oxygen via oxygen environment maintained by a servo-controlled system or nasal cannula with flow rates ≤1.

Beneficial effects of fluorescent pseudomonads on seed germination, growth promotion, and suppression of charcoal rot in groundnut (Arachis hypogea L.).

Rhizobacteria are used as inoculants to enhance crop yield and for biological control of fungal pathogens. Fluorescent pseudomonads isolated from the rhizosphere of groundnut showed suppression of the phytopathogen Macrophomina phaseolina that causes charcoal rot of groundnut, an economically important agroproduct. Two strains of fluorescent pseudomonads, designated as PS1 and PS2, were selected as a result of in vitro antifungal activity.

Antagonistic effect of fluorescent pseudomonads against Macrophomina phaseolina that causes charcoal rot of groundnut.

Maximum colony growth inhibition was observed due to Pseudomonas PS2 (74%) as compared to PS1 (71%) on trypticase soy agar (TSM) plates after 5 days of incubation. Light and scanning electron microscopic examination showed hyphal coiling, vacuolation, coagulation and granulation of cytoplasm resulting in lysis of hyphae of M. phaseolina by pseudomonads.

Antioxidant status, lipid peroxidation and nitric oxide end products in patients of type 2 diabetes mellitus with nephropathy.

Objectives: Oxidative stress is considered to be a unifying link between diabetes mellitus (DM) and its complications including nephropathy. The aim of the present study was to evaluate oxidative stress status in Asian Indian patients of type 2 DM with nephropathy.

Design And Methods: Serum levels of malondialdehyde (MDA) and nitric oxide end products (nitrite and nitrate), activities of erythrocyte superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH) content were estimated in controls, patients of type 2 DM without nephropathy (group 1) and with nephropathy (group 2).
