Bisphenol A (BPA) is a widely used endocrine disruptor that represents a significant risk to male reproductive function. Zinc (Zn) is vital for appropriate development of testes and to guarantee optimal testicular function and spermatogenesis. Our goal was to investigate if zinc oxide (ZnO), either in conventional or nanoformulation, could safeguard adult male rats' reproductive performance against the damaging effects of BPA. Signaling expression of CYP11A1 and Nrf-2 in the testis, testicular oxidant-antioxidant status, Bax/Bcl-2 apoptotic ratio, and histological examination of various reproductive organs were all evaluated. Twenty-eight adult male albino rats were divided randomly into 4 groups (7 animals each) including the control, BPA, conventional zinc oxide (cZnO) + BPA, and zinc oxide nanoparticles (ZnO-NPs) + BPA groups. The study was extended for 2 successive months. Our findings revealed strong negative effects of BPA on sperm cell characteristics such as sperm motility, viability, concentration and abnormalities. Additionally, BPA reduced serum levels of testosterone, triiodothyronine (T3), and thyroxine (T4). Also, it evoked marked oxidative stress in the testes; elevating malondialdehyde (MDA) and reducing total antioxidant capacity (TAC). BPA significantly downregulated testicular mRNA relative expression levels of CYP11A1 and Nrf-2, compared to control. Testicular apoptosis was also prompted by increasing Bax/ Bcl-2 ratio in testicular tissue. Histopathological findings in the testes, epididymis, prostate gland, and seminal vesicle confirmed the detrimental effects of BPA. Interestingly, cZnO and ZnO-NPs significantly alleviated all negative effects of BPA, but ZnO-NPs performed better. In conclusion, our findings point to ZnO, specifically ZnO-NPs, as a viable treatment for BPA-induced testicular dysfunction.

Fast-charging metal-ion batteries are essential for advancing energy storage technologies, but their performance is often limited by the high activation energy (E) required for ion diffusion in solids. Addressing this challenge has been particularly difficult for multivalent ions like Zn. Here, we present an amorphous organic-hybrid vanadium oxide (AOH-VO), featuring one-dimensional chains arranged in a disordered structure with atomic/molecular-level pores for promoting hierarchical ion diffusion pathways and reducing Zn interactions with the solid skeleton.

The increasing prevalence of dental pathogens and oral cancer calls for new therapeutic agents. Nanoparticle (NPs) based tumor therapy enables precise targeting and controlled drug release, improving anti-cancer treatment efficacy while reducing systemic toxicity. Zinc oxide NPs (ZnO NPs) are notable in nanomedicine for their exceptional physicochemical and biological properties.

Background: Cancer is the deadliest disease, and neurological disorders are also marked as slow progressive diseases, ultimately leading to death. Stopping two mouths with one morsel was the strategy that we used in this study.
Methods: We have synthesized peony-shaped zinc oxide nanoflowers (ZnO-NFs) and characterized them using various photophysical tools like UV-vis spectroscopy, zeta potential analysis, dynamic light scattering (DLS), FTIR, and scanning electron microscopy (SEM), and utilized these nanoflowers to monitor their anticancer and anti-amyloid activity.

Silver nanoparticles are recognized for potent antimicrobial properties against pathogenic bacteria, crucial in addressing the severity of leptospirosis, where an ideal treatment is lacking. This study focuses on assessing the antimicrobial efficacy of silver-doped zinc oxide nanoparticles (ZnO:9Ag) on standard Leptospira spp. strains (six species and ten serovars).

The environmental persistence of pharmaceuticals represents a significant threat to aquatic ecosystems and human health, while limitations in conventional wastewater treatment methods underscore the urgent need for innovative and eco-friendly degradation strategies. Photobiocatalytic approaches provide a promising solution for the effective degradation of pharmaceutical contaminants by harnessing the synergistic effects of both photocatalysts and biocatalysts. In this study, we developed a photobiocatalytic composite by co-immobilizing laccase enzyme and zinc oxide nanoparticles on bacterial cellulose synthesized from orange peel waste.
