Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

open access: yesClinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

A Fly in the Ointment? Non‐Target Fly Pest Benefits From Reduction in Ivermectin During Targeted Selective Treatment

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Targeted Selective Treatment (TST) can reduce the rate of resistance development in livestock gastrointestinal nematodes but can also reduce the effects of anthelmintics on non‐target organisms. Most studies of non‐target anthelmintic effects focus on beneficial species.

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

EMF2 deficiency disrupts epigenetic and chromatin organization landscapes, blocking root regeneration competence in Arabidopsis

open access: yesNew Phytologist, EarlyView.
EMF2 mutation alters transcriptomic profiles in Arabidopsis calli while retaining responsiveness during root induction. Summary Plant de novo organogenesis depends on callus formation, yet the epigenetic mechanisms governing organ regeneration remain poorly understood.

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).
