Determining the timeline of gonadal and genital differentiation in male and female equine fetuses allows for early detection and intervention in malformations

The Anatomical Record, EarlyView.
Abstract Sexual differentiation in the equine fetus involves coordinated morphogenetic processes that shape both the gonads and the genital ducts. Although the formation of testes and ovaries has been relatively well documented, the temporal dynamics and morphometric patterns of the mesonephric (Wolffian) and paramesonephric (Müllerian) ducts remain ...

Asthma and Testosterone [PDF]

Nature, 1966
IT was previously shown1,2 that testosterone is a powerful inhibitor of histamine and SRS* responses, and in view of the varying age incidence of status asthmaticus in the two sexes it was thought testosterone levels might have aetiological significance. Dutch workers have thought along similar lines3. Accordingly blood levels were measured in male and

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Testosterone and Cholesterol Vasodilation of Rat Aorta Involves L-Type Calcium Channel Inhibition

Advances in Pharmacological Sciences, 2010
Testosterone has rapid nongenomic vasodilator effects which could be involved in protective cardiovascular actions. Several authors suggested specific mechanisms to explain this effect, but this matter was not clarified yet.

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 ...

Testosterone and androstanediol glucuronide among men in NHANES III

BMC Public Health, 2018
Background Most of the androgen replacement therapies were based on serum testosterone and without measurements of total androgen activities. Whether those with low testosterone also have low levels of androgen activity is largely unknown.

Editorial Commentary: Estrogen Influences Shoulder Health

Arthroscopy, EarlyView.
Abstract Estrogen influences bone mineral density, muscle quality and quantity, and collagen synthesis, rotator cuff tearing, worse outcomes after rotator cuff repair, hyperlaxity, and adhesive capsulitis. In this commentary, we discuss the potential explanations for the highly significant associations between hormonal systemic birth control and a ...

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

Animal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

Mouse testicular macrophages can independently produce testosterone and are regulated by Cebpb

Biological Research
Background Testicular macrophages (TM) have long been recognized for their role in immune response within the testicular environment. However, their involvement in steroid hormone synthesis, particularly testosterone, has not been fully elucidated.
