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 ...

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

The Nuclear Receptor Testicular Receptor 4 Orchestrates Cytoskeletal Organization in a G Protein Subunit Alpha 12/Rho‐Associated Protein Kinase–Dependent Manner to Promote Myofibroblast Differentiation and Tissue Fibrosis in Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Objective Members of the superfamily of nuclear receptors have been implicated in inflammatory processes and pathologic tissue remodeling and have emerged as attractive targets for pharmaceutical intervention. However, the role of testicular receptor 4 (TR4; or Nr2c2) in fibroblast activation and rheumatologic diseases has not yet been investigated ...

Modern competency‐based teaching of human sexual development

Anatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.
