Objectives: Aging is a biological phenomenon that causes various disorders and diseases in body systems such as the reproductive system. One of the important factors in aging is oxidative stress, which facilitates the aging process through various mechanisms. The aim of this study is the investigation of effects of caffeic acid on the testicular damages in Dgalactose induced aging model in mice.
Materials And Methods: Forty male mice were randomly divided into 5 groups (n=8): 1) Control, 2) Sham, 3) Aging, 4) Aging + caffeic acid, and 5) Caffeic acid. Aging was induced through daily injection of D-Galactose (300 mg/kg, intraperitoneal) for 6 weeks. Caffeic acid (60 mg/kg, intraperitoneal) was injected daily for 6 weeks. One day after the last injection mice were killed and the testicle and epididymis were removed. Then, sperm parameters, factors of oxidative stress, and histopathological changes were evaluated.
Results: The results showed that aging significantly decreased the count, motility, and viability of sperm, and increased abnormal sperm and sperm DNA fragmentation in contrast to the control group (<0.05). In addition, MDA levels increased significantly in this group, and SOD, GPx, and TAC activity decreased (<0.05). Histological studies also showed the destruction of seminiferous tubules, and Johnson's score decreased (<0.05). Caffeic acid administration significantly improved the above disarrays (<0.05).
Conclusion: The results showed that caffeic acid reduces the adverse effects of aging on spermatogenesis in mice by reducing oxidative stress and increasing antioxidant defenses.

This study aims to identify the main chemical compounds, investigate the effects of different drying methods on the quality, and determine the appropriate drying method of Callicarpae Nudiflorae Folium. UPLC-UV-Q-TOF-MS was employed to characterize and identify 35 main compounds, including phenylethanoid glycosides, flavonoids, and iridoids in Callicarpae Nudiflorae Folium. A method for the simultaneous determination of 8 compounds with strong UV absorption and high content was established to evaluate the quality of Callicarpae Nudiflorae Folium dried by different methods.

Modified Atmosphere Packaging (MAP) is a conventional method used to prolong the shelf-life of fresh-cut vegetables, including lettuce. However, MAP-stored lettuce remains perishable, and its deterioration mechanism is not fully understood. Here, we utilized non-targeted LC-MS metabolomics to evaluate the effects of cutting and extended storage time on metabolite profiles of lettuce stored in MAP.

Unlabelled: This study investigates the optimization of bioactive components in thermosonicated black carrot juice using response surface methodology (RSM) and gradient boosting (GB) modeling techniques. Thermosonication, a combination of ultrasound and heat, was applied to enhance the nutritional quality of black carrot juice, which is rich in anthocyanins, phenolic compounds, and antioxidants. The study examined the effects of temperature, processing time, and ultrasonic amplitude on total carotenoid content (TCC), total anthocyanin content (TAC), ferric reducing antioxidant power (FRAP), and total phenolic content.
