On the basis of the data reported in the literature a model is proposed describing the kinetics of the post-irradiation recovery of the main spermatogenous epithelium populations. In studying the spermatogenous epithelium structure of rodents and comparing the experimental and theoretical curves the parameters necessary for the kinetics estimations have been quantitated and their specific variations analysed. From these the parameters have been obtained and the kinetic curves shaped with a reference to human spermatogenous epithelium.

Proteasome-mediated protein degradation is essential for maintaining cellular homeostasis, particularly during spermatogenesis, where extensive cellular transformations, such as spermatid differentiation, require precise protein turnover. A key player in this process is the ubiquitin-proteasome system (UPS). This study aimed to investigate proteasome enzymatic activity at different stages of the spermatogenic cycle within the seminiferous tubules of mice and explore the regulatory mechanisms that influence its proteolytic function.

The widespread use of polyethylene terephthalate (PET) in food and beverage packaging raises concerns about its potential health effects, particularly when PET-derived nanoplastics (PET-NPs) are released into the environment. This study investigates the reproductive toxicity of PET-NPs in male mice. Mice were exposed to PET-NPs at doses of 0.

Electronic address:
As a significant emerging and re-emerging pathogen in China, the widely spread of Duck Tembusu virus (DTMUV) caused enormous economic losses to poultry industry. On account of DTMUV diseases' main symptoms on haemorrhagic oophoritis, intensive attentions were focused on female reproductive organ. Nevertheless, the DTMUV infection of sperm and testis manifested that testis was an important vector for vertical transmission of DTMUV.

To investigate the regulatory mechanism mediated by hypothalamic OPN5 on seasonal changes in the reproductive activities of domestic geese, 60 Magang ganders in their breeding period were selected for the experiment and evenly divided into an immunization group(OPN5-IM) and a control group. On days 0, 15 and 30, ganders in the immunized group were immunized with OPN5-KLH protein vaccine, and ganders in the control were immunized with the same amount of blank emulsified vaccine. Additionally, 120 female geese were provided to stimulate the reproductive activities of male geese.

The damaged organ may experience severe pathological alterations as a result of tissue ischemia-reperfusion (I/R). The study of stem cell-based repair therapies is actively being conducted, and the outcomes and therapeutic potential of these cells are both promising. Autophagy checks protein homeostasis by breaking down huge damaged proteins or organelles.
