Arsenic trioxide (As2O3) has shown effectiveness in treatment of leukemia but is also associated with reproductive toxicity. Since remediation with N-acetylcysteine (NAC) may mitigate the adverse effects caused by exposure, we assessed the effects of As2O3 and its potential reversibility after exposure cessation or coadministration of NAC. Animals received 0.3 or 3.0 mg/Kg/day of As2O3 subcutaneously and 40 mM of NAC in tap water. As2O3 treatment impaired spermatogenesis and sperm motility and decreased seminal vesicle weight and testosterone serum levels; after suspension of treatment, these parameters remained altered. When NAC was administered, animals showed improvement in sperm parameters and seminal vesicle weight. In vitro epididymal contractility was increased in As2O3-treated animals. We concluded that As2O3 is toxic to the male mouse genital system by compromising sperm quality and quantity; these effects persisted even after suspension of the treatment. However, the coadministration of NAC ameliorates the harmful effects of the drug on the male genital system.

BACKGROUND Perineal injuries affecting the scrotum and penis are rare in pediatric patients, owing to the protective anatomy of the male genitalia. However, when such injuries do occur, timely surgical intervention is crucial. This kind of damage might not be life-threatening but could cause functional disorders and have a huge impact on the patients' psychological condition if not treated appropriately, especially as they enter puberty.

A niche in the context of microorganisms defines the specific ecological role or habitat inhabited by microbial species within an ecosystem. For the human commensal Malassezia, the skin surface is considered its primary niche, where it adapts to the skin environment by utilising lipids as its main carbon and energy source. However pathogenic characteristics of Malassezia include the production of allergens, immune modulation and excessive lipid utilisation, which result in several diseases such as pityriasis versicolor, seborrheic dermatitis, Malassezia folliculitis and atopic dermatitis.

Libido plays a crucial role in influencing semen quality, yet the underlying regulatory mechanisms remain unclear. As a central axis in male goose reproduction, the hypothalamic-pituitary-testicular-external genitalia (HPTE) axis may contribute to the regulation of this process. In this study, we established a rating scale for goose libido based on average number of massages to erection (ANM) and the erection type, and evaluated semen quality across the entire flock.

Background: Alzheimer's disease (AD) is a common form of dementia characterized by the accumulation of amyloid beta (Aβ) and phosphorylated tau proteins in the brain. While clinical observations are typically used for AD diagnosis, postmortem studies have revealed individuals without dementia symptoms but with high AD pathology, known as resilient individuals. Calcium permeable AMPA receptors (CP-AMPARs) have been implicated in the calcium dyshomeostasis of AD, but it is unclear whether they are found or behave differently at the electrophysiological level in resilient and control individuals compared to AD patients.
