A systematic review of the physiological and biomechanical differences between males and females in response to load carriage during walking activities.

The purpose of this review was to systematically assess literature on differences between males and females in the physiological and biomechanical responses to load carriage during walking. PubMed, CINAHL, Scopus, Web of Science and the Cochrane library were searched. A total of 4637 records were identified and screened.

Monitoring the physical demands of training in Rugby League: the practices and perceptions of practitioners.

The physical demands of elite sport are often monitored with the aim of making evidence-based decisions to enhance performance and reduce injury risk. However, there is limited evidence in rugby league of the monitoring practices and perspectives of practitioners. This study provides a cross-sectional view of practices and perspectives of rugby league practitioners engaged in monitoring the physical demands of training.

The Physical and Physiological Match-Play Locomotor Activity Profiles of Elite Domestic Male Field Hockey.

A new four-quarter match format in field hockey has meant that the locomotor activity profiles of the sport are inconsistent with the literature. The aim of this investigation was to identify the physical and physiological demands of national-level male hockey players. Thirty-two male players participated in the study.

WssI from the Gram-negative bacterial cellulose synthase is an O-acetyltransferase that acts on cello-oligomers with several acetyl donor substrates.

In microbial biofilms, bacterial cells are encased in a self-produced matrix of polymers (e.g., exopolysaccharides) that enable surface adherence and protect against environmental stressors.

New Insights into the Chloroplast Outer Membrane Proteome and Associated Targeting Pathways.

Plastids are a dynamic class of organelle in plant cells that arose from an ancient cyanobacterial endosymbiont. Over the course of evolution, most genes encoding plastid proteins were transferred to the nuclear genome. In parallel, eukaryotic cells evolved a series of targeting pathways and complex proteinaceous machinery at the plastid surface to direct these proteins back to their target organelle.

Functional Oligomeric Forms of Uncoupling Protein 2: Strong Evidence for Asymmetry in Protein and Lipid Bilayer Systems.

Stoichiometry of uncoupling proteins (UCPs) and their coexistence as functional monomeric and associated forms in lipid membranes remain intriguing open questions. In this study, tertiary and quaternary structures of UCP2 were analyzed experimentally and through molecular dynamics (MD) simulations. UCP2 was overexpressed in the inner membrane of , then purified and reconstituted in lipid vesicles.

Seasonal changes in glenohumeral joint isokinetic strength in professional rugby league players.

Objective: To assess glenohumeral joint (GHJ) rotation strength across a rugby league season, since strength of rotator cuff musculature may protect against contact injuries to the shoulder.

Design: A prospective cohort study was used to compare GHJ rotation pre-, in-, and post-season.

Setting: Laboratory.
