Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

Beyond biologic sex: Exploratory insights into the heterogeneity of hormonal and contextual drivers of periodontal and peri‐implant outcomes

Periodontology 2000, EarlyView.
Abstract Background Periodontal and peri‐implant diseases are multifactorial inflammatory conditions influenced by microbial, host, hormonal, genetic, and behavioral factors. Although sex‐based differences in immune and inflammatory responses are well recognized in medicine, the extent to which biologic sex and hormonal status influence the prevalence,

Ground mammal colonization of restored wildlife corridors in the tropical uplands of north‐eastern Australia

Restoration Ecology, EarlyView.
Abstract Introduction Since European settlement, Australia's Wet Tropics bioregion has been extensively cleared, leaving a mosaic of rainforest fragments, crops, pastures, orchards, and human settlement. Fragment isolation leads to declines in faunal diversity and genetic variability, effects potentially exacerbated by climate change. Restoring habitat

Fluvastatin Plus Dipyridamole Suppresses Canine Hemangiosarcoma Growth in Patient‐Derived Xenograft Models Through Lactate Dehydrogenase‐Associated Cholesterol/Lipid Metabolism

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Tumour cells commonly exhibit aerobic glycolysis and produce lactate despite oxygen availability. Lactate dehydrogenase (LDH) catalyses pyruvate‐lactate interconversion and regulates intracellular lactate levels. Endothelial cells also depend on glycolysis for ATP production, which prompted us to investigate LDH in canine hemangiosarcoma (HSA),

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

Exercise during 14 days of head down tilt bedrest attenuates motor unit impairments in older humans

Experimental Physiology, EarlyView.
Abstract Head‐down tilt bedrest (HDBR) models the effects of mechanical unloading on neuromuscular function. The efficacy of exercise in preserving motor unit (MU) function in older adults during HDBR remains unclear. This study investigated the effects of 14‐day HDBR on MU properties in older adults and the protective role of exercise.

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Mitochondrial haplotype and sex modulate responses to endurance exercise training

The Journal of Physiology, EarlyView.
Abstract figure legend Using OKC‐HETB/W rats we demonstrate that mitochondrial haplotype influences training responses of endurance exercise. Overall OKC‐HETW rats showed greater responses than OKC‐HETB in exercise tolerance, mitochondrial bioenergetics, mitochondrial DNA (mtDNA) mutation frequencies and motor co‐ordination.

Semaglutide impacts skeletal muscle to a similar extent as caloric restriction in mice with diet‐induced obesity

The Journal of Physiology, EarlyView.
Abstract figure legend Four weeks of semaglutide treatment causes significant reductions in total body weight, fat mass, lean mass, and grip strength in mice with diet induced obesity. Mice treated with semaglutide lost a greater amount of total body weight and fat mass compared to mice fed fed a calorie matched diet.

Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

The Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...
