The epididymis, a key component of the male reproductive system, controls spermatozoa's maturation, fertility, and storage. The objective of this study is to evaluate the histological, ultrastructural, and immunohistochemical variations in the epididymis of donkeys that occur throughout the year. During the breeding season (spring) and nonbreeding seasons (summer, autumn, and winter), 20 epididymis were collected from adult, clinically healthy donkeys. Compared to non‐breeding seasons, the epididymal duct displayed a more active lining epithelium and more sperm in the lumen during the breeding season. The epithelial height is the lowest and the lumen is the widest during the breeding season. Furthermore, the epididymal epithelium in the tail region exhibits undulations with polyps‐like projections. The epididymal epithelium is composed mainly of the principal, basal, and dark cells. Tight junction between adjacent principal cells is more obvious in the breeding season as compared to the non‐breeding seasons. However, intraepithelial lymphocytes, phagocytic, and other immune cells are more frequent in non‐breeding seasons. β‐catenin, which is a component of the adherent junctions between adjacent PCs, exhibits more immunoreactivity during the spring. On the other hand, iNOS, an indicator of oxidative stress, reacts positively during the summer. Additionally, during non‐breeding seasons, autophagy was detected within the epididymal epithelium which may be linked to stress adaptation. In conclusion, our findings suggest that the histological and ultrastructural characteristics of the epididymal epithelium are more active during spring compared to other seasons of the year.Research Highlights The study aimed to evaluate the histological, ultrastructural, and immunohistochemical variations in the blood epididymal barrier (BEB) and epididymal epithelium of donkeys that occur throughout the year. In comparison to non‐breeding seasons, the epididymal duct displayed a more active lining epithelium and more sperm in the lumen during the breeding season. The epithelial height is the lowest and the lumen is the widest during the breeding season. The epididymal epithelium in the tail region exhibits undulations with polyps‐like projections that increase the surface area. β‐catenin, which is a component of the adherent junctions between adjacent PCs, exhibits more immunoreactivity during the spring. On the other hand, iNOS, an indicator of oxidative stress, reacts positively during the summer.

“…Nature offers a range of possible sources and insights toward nanomaterial production. Myconanotechnology is a term used to describe the green synthesis of metallic and non-metallic nanoparticles from a range of organic metabolites present in fungi like yeast, mold, and mushrooms, although macrofungi produce a massive amount of fruitbodies, mycelia, & enzymes, are extremely effective in the mycosynthesis of nanoparticles [4] . Riboflavin is a light-sensitive and water-soluble compound, and its function is a bound coenzyme.…”

In the current investigation, a macrofungus was collected from Quaid-i-Azam University Islamabad. The collected fungus was identified as Ganoderma multipileum, and further exploited for the synthesis of nanoparticles using zinc metals. Chemical and morphological characterization of synthetized nanoparticles was through Fourier Transfer InfraRed spectroscopy analysis (FTIR), X-ray diffraction analysis (XRD), Energy dispersive X-ray analysis (EDX), Scanning Electron Microscopy analysis (SEM) and UV-Vis spectrum showed a broad absorption between 350 and 380 nm, which indicates the synthesis of ZnO NPs. ZnONPs have been used in a variety of biomedical studies including such as biocompatibility, antifungal, antileishmanial, and antibacterial studies. abilities, antifungal, antileishmanial, and antibacterial studies. The ZnO nanoparticles showed a strong antibacterial effect against gram-positive (Klesbsilla pneumonia and Staphylococcus aureus) and gram-negative (Eschericia coli and Pseudomonas aeruginosa) bacteria. Furthermore, the ZnO nanoparticles also showed a high antifungal effect against different fungus. The current study concludes that Ganoderma multipileum works as a novel and eco-friendly source for the synthesis of ZnO NPs with prominent biological application that can be further applied in different fields.

The current study was carried out to synthesize iron oxide nanoparticles (IONPs) via green reduction method from a wild mushroom collected from Quaid‐i‐Azam University, Islamabad, Pakistan. The collected fungus was identified as Daedalea sp. based on morphological characteristics. Prepared NPs were produced from iron chloride hexahydrate with fungal filtrate via combustion method. The as prepared NPs were characterized by using different techniques for example, scanning electron microscopy (SEM), X‐ray diffractions (XRD), Fourier transform infrared spectroscopy (FT‐IR), and ultraviolet visible (UV‐Vis) spectroscopy. Morphology and size of the NPs were determined by SEM analysis. XRD study revealed crystalline nature of IONPs. The FT‐IR spectrum exhibited peak at 3390.26 cm−1 stretching that described the strong O–H band of the alcohol associated with mushroom texture. The major IONPs dose (0.75 mg/ml) demonstrated 71% growth inhibition against Aspergillus. Excellent antibacterial activities against Pseudomonas aeruginosa (28 mm), and Klesbsilla pneumonia (28 mm) were represented by the fabricated NPs. Further, highest reducing power (53.22 ± 0.72 µg AAE/mg) was shown by the highest administrated dose (400 µg/ml). Maximum 2,2‐diphenyl‐1‐picrylhydrazyl and trolox antioxidant activity free radical scavenging activities at 400 µg/ml IONPs concentration were noted as 51.29 ± 0.48, and 83.12 ± 0.28 trolox equivalent antioxidant capacity, respectively. In brief, the negligible hemolytic activity against human red blood cells at the highest concentration (400 µg/ml), as well as, moderate antioxidant activities at low concentration suggest the application of the fabricated NPs in environmentally sound viable hygiene production.
