Firearm screening in pediatric patients.

Introduction: In the United States, firearm-related injuries are the leading cause of death among children and adolescents 1-19 years of age. Although many pediatricians believe addressing firearm safety is important and have guidance from organizations like the American Academy of Pediatrics, few routinely screen and counsel on firearm safety. The goal of this project was to screen all patients presenting to the pediatric emergency department, pediatric floor, and pediatric intensive care unit for the presence of firearms in the home, firearm storage practices, and whether they had previously received any firearm counseling by medical professionals.

Undergraduates' knowledge, attitudes, and behaviours associated with fad diets.

Purpose: We aimed to determine undergraduate students' use and knowledge of fad diets as well as examine how appealing students found these diets given the goal of rapid weight loss and/or improved health. Twenty-three students from a Midwestern university (mean age = 19.2, mean BMI = 27.

Mitochondrial Irc3 helicase of the thermotolerant yeast Ogataea polymorpha displays dual DNA- and RNA-stimulated ATPase activity.

Irc3 is one of the six mitochondrial helicases described in Saccharomyces cerevisiae. Physiological functions of Irc3 are not completely understood as both DNA metabolic processes and mRNA translation have been suggested to be direct targets of the helicase. In vitro analysis of Irc3 has been hampered by the modest thermostability of the S.

Outcomes of Children With Firearm Injuries Admitted to the PICU in the United States.

Objectives: Firearm-related injury is the second leading cause of injury and death for children 1-18 years old in United States. The objective of our study was to analyze the outcomes of children admitted to the PICU with firearm injuries.

Design: Retrospective study.

Irc3 is a monomeric DNA branch point-binding helicase in mitochondria of the yeast Saccharomyces cerevisiae.

Irc3 is a superfamily II DNA helicase required for the maintenance of mitochondrial DNA stability in Saccharomyces cerevisiae. Here, we show that recombinant Irc3 is a monomeric protein and that it can form a binary complex with forked DNA. The catalytically active enzyme is a monomer as no positive cooperativity of ATP hydrolysis or DNA unwinding can be detected.
