The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Systemic Hormonal Contraceptive Use Is Associated With Greater Odds of Rotator Cuff Tears, Shoulder Instability, Dislocation, and Other Shoulder Pathologies: A Propensity Matched Epidemiological Study

Arthroscopy, EarlyView.
Purpose To evaluate whether systemic estrogen‐only, progestin‐only, or combined hormonal contraceptives (HCs) are associated with increased risk of shoulder pathologies in reproductive‐age females. Methods A retrospective cohort study of female patients presenting to clinic from 2013 to 2020 and aged 13‐50 with 5 years of follow‐up was conducted using ...

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

Animal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Tissue‐Specific and Spatially Dependent Metabolic Signatures Perturbed by Injury in Male and Female Mice

Arthritis &Rheumatology, EarlyView.
Objective Osteoarthritis, the leading cause of disability worldwide, disproportionately affects women, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.

Interaction of the Gut Microbiota and the Enteric Nervous System: Implications in Gastrointestinal Disorders Associated With Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social interaction, restricted interests, and repetitive behaviors. In addition to these core behavioral symptoms, gastrointestinal (GI) disorders are frequently reported, ranging from severe constipation to diarrhea.

Sexual Dimorphism in the Regulation of Estrogen, Progesterone, and Androgen Receptors by Sex Steroids in the Rat Airway Smooth Muscle Cells

International Journal of Endocrinology, 2016
The role of sex hormones in lung is known. The three main sex steroid receptors, estrogen, progesterone, and androgen, have not been sufficiently studied in airway smooth muscle cells (ASMC), and the sex hormone regulation on these receptors is unknown ...
