Thus, this study assessed SAC's influence and putative mechanisms on male fertility among SAC consumers. Fifty adult male Wistar rats were randomly split into five groups (n = 10): control (5 ml D.

The administration was via gavage for 56 days. Animals were sacrificed under intraperitoneal ketamine (4 mg/kg) and xylazine (40 mg/kg). We obtained blood samples via cardiac puncture and centrifuged them to obtain serum for biochemical analysis. We removed and weighed the testes, epididymis, prostate, and seminal vesicle. The samples were tested for oxidative stress markers, cytokines, and apoptotic markers using ELISA. There were elevated levels of oxidative stress, xanthine oxidase/uric acid levels, inflammation, and cell death resulting in compromised steroidogenesis and spermatogenesis and diminished sperm quality.

A targeted literature review of 55 peer-reviewed studies published over the past 25 years was conducted, focusing on global TBBPA occurrence in environmental media, occupational and residential settings, and biological matrices. Exposure pathways assessed include dermal contact dust ingestion, and inhalation. Quantitative exposure estimates were generated or extracted where available and compared against established toxicological reference values, including the European Food Safety Authority (EFSA) tolerable daily intake (TDI) of 0.7 μg/kg body weight/day and a derived oral Reference Dose (RfD) of 0.26 mg/kg/day for cancer.

Likewise, a basic deterministic aggregate exposure assessment shows that upper bound exposure estimates for both an office worker and a worker in an electronics dismantling facility result in the Hazard Index (HI) < 1.

Employing an integrative approach that combines bioinformatics analysis of public cancer databases (TCGA), molecular docking simulations, and in vitro experiments, we identified four immune-related genes—CCL19, KLRB1, CD40LG, and IGLL5—that are potentially modulated by PET-MPs. Molecular docking indicated that bis(2-hydroxyethyl) terephthalate (BHET), a key PET oligomer, binds with high affinity to these proteins, suggesting that PET-MPs may alter immune homeostasis within the tumor microenvironment (TME). Additionally, PET-MPs induced a pro-inflammatory cytokine response, including elevated IL-6 and TNF-α secretion, which could promote tumor progression. Our findings further suggest that PET-MPs may enhance BC cell proliferation and survival through immune modulation. However, limitations include the lack of immune cell co-culture models and in vivo validation.
