Evaluation of therapeutic effects of D‐limonene following orchiopexy in the rat model of cryptorchidism

Animal Models and Experimental Medicine, EarlyView.
D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Three-dimensional reconstruction of rat sperm using volume electron microscopy

Acta Biochimica et Biophysica Sinica
Three-dimensional (3D) reconstruction serves as a crucial instrument for the analysis of biological structures. In particular, a comprehensive and accurate 3D ultrastructural examination of rat sperm is vital for understanding and diagnosing male ...

Spermatid cyst polarization in Drosophila depends upon apkc and the CPEB family translational regulator orb2. [PDF]

PLoS Genetics, 2014
Mature Drosophila sperm are highly polarized cells--on one side is a nearly 2 mm long flagellar tail that comprises most of the cell, while on the other is the sperm head, which carries the gamete's genetic information.

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

Time-lapse imaging of Drosophila testis for monitoring actin dynamics and sperm release

STAR Protocols, 2022
Summary: Here we describe a simple step-by-step protocol for collecting high-resolution, time-lapse images of intact Drosophila testis ex vivo for a limited period using a confocal microscope, with minimum photo-toxic damage, to monitor spermatid ...

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.

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 ...
