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 ...

Nonapeptide cell size differs between male morphs of the West African cichlid, Pelvicachromis pulcher

Journal of Fish Biology, EarlyView.
Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

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.

A mini‐review of chronic suppression of the hypothalamic–pituitary–adrenal axis in animals with P‐glycoprotein deficiency

Journal of Small Animal Practice, EarlyView.
This mini‐review describes the pathophysiology of the disrupted hypothalamic–pituitary–adrenal axis in dogs, and probably cats, with the MDR1 (ABCB1) mutation, ABCB1‐1Δ in dogs and ABCB11930‐1931del TC in cats. Clinical consequences in affected animals are discussed and therapeutic interventions to consider are presented.
