JGP study (Steinz et al. https://doi.org/10.1085/jgp.202313515) reveals that oxidative stress can induce stable posttranslational modifications of RyR1 that increase the channel's open probability and could therefore disrupt muscle contractility.

Background: To gain optimal positioning to make sure the game laws are applied in uniform way, the performance of field referee must be periodically evaluated to have constantly adequate training during a match and during the competitive season. Considering that field Yo-Yo Intermittent Recovery Test-Level 1 is frequently employed in elite team sport players to estimate maximal oxygen uptake (VO
Methods: During off-season, 20 male (21.

Aims: Few studies have explored empowerment as a predictor of mental health outcomes in geriatric healthcare professionals. This research addresses this gap by using the 'effort-reward imbalance' theory of work-related stress to develop a comprehensive model, examining the role of psychological empowerment in the psychological outcomes of nursing home professionals.
Design: This cross-sectional exploratory study used structural equation modelling (SEM) to test a model on the mediating role of psychological empowerment in the relationship between effort-reward ratio and burnout, anxiety and depression.

Objectives: Endoplasmic reticulum (ER) stress-induced protein homeostasis perturbation is a core pathological element in the pathogenesis of neurodegenerative diseases. This study aims to clarify the unique role played by C/EBP homologous protein (CHOP) as a biomarker of the unfolded protein response (UPR) in the etiology of chronic pain and related cognitive impairments following chronic constrictive nerve injury (CCI).
Methods: The memory capability following CCI was assessed utilizing the Morris water maze (MWM) and fear conditioning test (FCT).

Comparative finite element analysis involves standardising aspects of models to test equivalent loading scenarios across species. However, regarding feeding biomechanics of the vertebrate skull, what is considered "equivalent" can depend on the hypothesis. Using 13 diversely-shaped skulls of marsupial bettongs and potoroos (Potoroidae), we demonstrate that scaling muscle forces to standardise specific aspects of biting mechanics can produce clearly opposing comparisons of stress or strain that are differentially suited to address specific kinds of hypotheses.
