Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1

Molecular Microbiology, EarlyView.
A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

Fascinating single‐cell red algae: models for evolution and adaptation

New Phytologist, EarlyView.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Optimization of photobiomodulation therapy for spinal cord injury: A review

Photochemistry and Photobiology, EarlyView.
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica Scripta, EarlyView.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Exercise training to preserve vitality capacity in ageing

Experimental Physiology, EarlyView.
Abstract Ageing is an escalating global health issue, with the World Health Organization (WHO) reporting that one in six individuals will be 60 years or older by the year 2030. Therefore, understanding the mechanisms of complex biological ageing processes and associated healthcare challenges has become increasingly important.

Bed rest decreases resting skeletal muscle O2 uptake and resting energy expenditure in young and elderly subjects

Experimental Physiology, EarlyView.
Abstract A decrease in resting muscle O2 uptake (V̇O2m${\dot V_{{{\mathrm{O}}_2}{\mathrm{m}}}}$) described during bed rest (BR) could determine a decreased whole‐body resting energy expenditure (REE), potentially useful during prolonged spaceflights. Two groups of recreationally active men (young [Y], n = 8, age 23 ± 5 years; elderly [E], n = 10, age ...

One day of environment‐induced heat stress causes injury to the murine kidney

Experimental Physiology, EarlyView.
Abstract Environment‐induced heat stress (EIHS) results from sustained body temperature elevation owing to prolonged exposure to heat and humidity. We hypothesized that EIHS would cause kidney injury and cellular dysfunction. To test this hypothesis, female C57 mice were exposed to EIHS (n = 14; 37.6°C, 42.0% relative humidity) or thermoneutral (TN ...

Mitochondrial alterations as potential early events in neuromuscular junction remodelling with muscle disuse

Experimental Physiology, EarlyView.
Abstract Physical inactivity impairs neuromuscular health, promoting skeletal muscle atrophy, mitochondrial changes, and neuromuscular junction (NMJ) instability. However, the interplay between mitochondria and NMJ alterations in the context of muscle disuse remains underexplored.
