The effect of gonadotropin-releasing hormone or human chorionic gonadotropin administration at mating on lambing performance in konya merino yearling ewes [PDF]

Eurasian Journal of Veterinary Sciences
Aim: In this study, it was aimed to determine the effects of the exogenous gonadotropin-releasing hormone (GnRH) or human chorionic gonadotropin (hCG) application at mating on lambing performance in synchronization and following cycle in Konya Merino ...

Puberty timing and cognitive functioning: insights from the Adolescent Brain Cognitive Development (ABCD) study and Mendelian randomization

Journal of Child Psychology and Psychiatry, EarlyView.
Background Early puberty timing is linked to altered neurodevelopment and adverse mental health outcomes, yet its relationship with cognitive functioning remains unclear. We examined the effects of puberty timing across multiple cognitive domains.

Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

Journal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...

Recent advances in polyendocrine metabolic ovarian syndrome, formerly polycystic ovary syndrome, with emphasis on endocrine and metabolic dysfunction and cardiovascular risk

Journal of Internal Medicine, EarlyView.
Abstract Polyendocrine metabolic ovarian syndrome (PMOS), previously known as polycystic ovary syndrome, affects 10%–13% of women of reproductive age and remains underdiagnosed despite its substantial health burden. The introduction of the new PMOS nomenclature in 2026 reflects a fundamental shift in understanding the condition as a lifelong endocrine ...

A Systematic Review and Meta‐Analysis of Biological Sex Differences in Sleep Spindles and Slow Wave Activity in Adults With and Without Insomnia

Journal of Sleep Research, EarlyView.
ABSTRACT Mounting evidence shows sex‐based differences in sleep experiences and outcomes, including the prevalence of insomnia disorder. However, the impact of biological sex on brain oscillations during sleep remains poorly understood, especially in the context of insomnia disorder. This is a notable gap, given that neurophysiological aspects of sleep

Marine flatworms as windows into the evolution of bilaterian neuropeptide signalling. [PDF]

J Neuroendocrinol
Abstract The evolutionary origin(s) of neuropeptide signalling is still largely unknown. It has been hypothesised that signal transmission via neuropeptides played a crucial role in the regulation of nervous systems in the bilaterian ancestor. Identification, expression and functional analyses of neuropeptides and their receptors across different ...

Menopause and vascular endothelial health: Is it all about the oestrogen?

Experimental Physiology, EarlyView.
Abstract Cardiovascular disease (CVD) is a leading cause of mortality in women, and CVD risk is accelerated during the menopause transition. This acceleration has traditionally been attributed to the hallmark decline in oestradiol with menopause. However, the menopause transition is also characterized by changes in other sex hormones that exert effects

Exploring lifestyle management in polycystic ovary syndrome through implementation frameworks

Experimental Physiology, EarlyView.
Abstract Polyendocrine metabolic ovarian syndrome [PMOS; previously known as polycystic ovary syndrome (PCOS)] is an endocrine condition affecting 10%–13% of women of reproductive age, with cardiometabolic, reproductive and psychological features. The PMOS guidelines have established recommendations for its management, which can include pharmacological,

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...
