Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

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

Effectiveness of myoinositol versus metformin as adjuvant treatment on infertile PCOS women undergoing ovulation induction cycles prospective cohort study

Journal of Medicine in Scientific Research
Background In anovulatory infertility Polycystic ovary syndrome (PCOS) plays a leading role, characterized by endocrine and metabolic disturbances. While metformin is usually used to decrease insulin resistance and restore ovulation, myoinositol has ...

Poly(lactic‐co‐glycolic acid) microsphere loaded dissolving microneedles for sustained and coordinated transdermal delivery of desogestrel and ethinyl estradiol

Bulletin of the Korean Chemical Society, EarlyView.
PLGA‐based sustained‐release microneedles were developed for the delivery of desogestrel and ethinyl estradiol. The system enabled coordinated release of both drugs, suggesting its potential to improve dosing convenience as a long‐acting contraceptive platform.

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
