Lipid modulation contributes to heat stress adaptation in peanut.

At the cellular level, membrane damage is a fundamental cause of yield loss at high temperatures (HT). We report our investigations on a subset of a peanut () recombinant inbred line population, demonstrating that the membrane lipid remodeling occurring at HT is consistent with homeoviscous adaptation to maintain membrane fluidity. A major alteration in the leaf lipidome at HT was the reduction in the unsaturation levels, primarily through reductions of 18:3 fatty acid chains, of the plastidic and extra-plastidic diacyl membrane lipids.

Analysis of Cotton Leafroll Dwarf Virus P0 Gene Sequences from South Carolina Reveals Low Variability Among Isolates.

Cotton leafroll dwarf virus (CLRDV) is emerging across the major cotton-producing states of the southern United States. Because it was detected in nearly all cotton-producing states within a few years of its initial detection in the United States, the spread of the virus has apparently occurred rapidly. In this study spanning three growing seasons in South Carolina, we collected CLRDV isolates from symptomatic and asymptomatic cotton plants in 10 counties.

The Junior Fellows Program: motivating urban youth toward careers in health, science, and medicine.

Lack of diversity in the health, science, and medical professions has been documented as a contributor to health disparities in the United States, and early intervention is essential for the recruitment of underrepresented students into the health professions. The Junior Fellows Program, a partnership between the New York Academy of Medicine, New York City public schools, and regional academic medical centers, is designed to stimulate students' interest in health, science, medicine, and research. From seminars designed to advance Junior Fellows' skills in identifying concrete strategies for improving health and preventing illness, to understanding the research process and the nature of scientific inquiry, the program engages Junior Fellows in project-based learning, works to enhance their critical thinking skills, and helps them to foster positive interactions with practicing physicians and health professionals.

Double-blind, randomized study of nalmefene and naloxone in emergency department patients with suspected narcotic overdose.

Study Objectives: To compare the efficacy, safety, and withdrawal symptoms in emergency department patients with suspected narcotic overdose treated with nalmefene, an opioid antagonist with a 4- to 10-hour duration of action, with those treated with naloxone.

Methods: Adults in 9 centers who would otherwise receive naloxone for altered consciousness levels were randomly assigned to receive intravenous study drug (1 mg nalmefene, or 2 mg nalmefene or 2 mg naloxone, double-blinded) every 5 minutes as needed for up to 4 doses in a 4-hour study. Outcomes were 20-minute and 4-hour posttreatment changes in respiratory rates, Neurobehavioral Assessment Scale scores, Opioid Withdrawal Scale scores, and incidences of adverse events.

The effect of the menstrual cycle on asthma presentations in the emergency department.

Background: Seventy-five percent of all adult hospital admissions for asthma are women.

Objective: To determine whether a relationship exists between phases of the menstrual cycle and asthma exacerbations in adult females.

Methods: Data were analyzed from 182 nonpregnant, adult females with asthma aged 13 years to menopause.
