Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, EarlyView.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Organoids and organ‐on‐a‐chip models for investigating the pathophysiology of the human reproductive system

Interdisciplinary Medicine, EarlyView.
Organoids and organ‐on‐a‐chips are advancing reproductive system research. In the female reproductive system, applications include cancer organoid models, placental chips, and hormone simulation models. For the male reproductive system, research focuses on drug resistance mechanisms, co‐culture platforms, and infertility studies. These refined in vitro

Immunolocalization of Adrenoceptors in the Reproductive Tract of Male Domestic Cats in Comparison to Rats

Animals, 2021
Adrenoceptors mediate the action of the sympathetic nervous system, including the contraction of the epididymis and vas deferens. The aim of this study was to immunolocalize the adrenergic receptors in the reproductive tract of the male cat, as this ...

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

Journal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

A Case of Duplicated Vas Deferens Found Incidentally during Varicocelectomy

The World Journal of Men's Health, 2013
Duplication of the vas deferens is a very rare congenital anomaly in which two vasa deferentia coexist within the spermatic cord. Duplication of the vas deferens can be found during herniorrhaphy, vasectomy, and varicocelectomy performed on the spermatic

Comparative Digital Estrogen Receptor Alpha (ERα) Expression Analysis in Benign and Malignant Prostate Tissue of Men and Dogs

The Prostate, EarlyView.
ABSTRACT Background The dog is the only large mammal, other than humans, that commonly develops spontaneous prostate cancer (PCa) and is, therefore, considered a valuable model for comparative studies. Estrogens are critical for normal prostate development and contribute to prostatic carcinogenesis in men.
