Summary: Effective evaluation methods for assessing the nutritional quality of foods that eliminate free radicals have long attracted the attention of scientists and the populace. Constructing a photoelectrochemical sensor that is intuitive, rapid, and capable of accurately assessing global antioxidant capacity is of profound significance. The internal influences of compound structure on antioxidant synergistic behaviors were revealed, providing a potential guide for health care diets.

Summary: This research investigates four different assays to determine the antioxidant capacity of standard substances, organosolv lignins, and kraft lignins. The lowest variation was found in the ABTS assay, while the highest was found in the DPPH assay. The FRAP and FC assays show the best correlation and indicate a single electron transfer mechanism, while DPPH has a different reaction mechanism. Lignins from different sources possess different antioxidant capacities and can be used in various applications.

Summary: This study explores the effects of selenium therapy on semen parameters, antioxidant capacity, and sperm DNA fragmentation in infertile patients with idiopathic oligoasthenoteratospermia. Results showed that selenium therapy significantly improved sperm concentration, motility, and antioxidant capacity, while reducing sperm DNA fragmentation. Therefore, selenium could be a promising therapy for male infertility.

Summary: This study aimed to investigate the effects of L-citrulline on reproductive hormone levels, antioxidant capacity, and semen quality in rams. The results showed that supplementation with L-citrulline improved semen quality, increased reproductive hormone levels, and enhanced antioxidant capacity in rams. The best results were obtained with a daily supplementation of 12 g.

Summary: The study investigated the effects of melatonin (MLT), reduced glutathione (GSH), and vitamin E (Vit. E), as well as their combinations, on semen cryopreservation of Mediterranean buffalo. The quality parameters and in vitro fertilization (IVF) performance of frozen-thawed sperm were evaluated. The results showed that MLT, GSH, and Vit. E had positive effects on antioxidant capacity, kinetics, morphology, and embryo development rates. The combination of 0.4 mg/mL Vit. E and 0.2 mg/mL MLT showed the highest efficiency in protecting frozen-thawed sperm and improving IVF outcomes. These findings suggest the potential for developing a specialized semen freezing extender for Mediterranean buffalo.

Summary: This study examined the effects of metal exposure on semen quality and the role of oxidative damage. The results showed that the mixed exposure to metals was negatively associated with semen volume, with cadmium and manganese as the major contributors. The total antioxidant capacity (TAC) may play a mediating role in this process. GSTT1 and GSTM1 can modify the reduction in the total sperm count caused by seminal nickel exposure.

Summary: Cryopreservation of fish sperm is a rapidly evolving technique with potential benefits in genetic reproduction programs and conservation efforts. The use of cryoprotectants and antioxidants, such as melotonin, is crucial to minimize damage to the sperm during the freezing and warming processes. Further research is needed to explore the positive effects of melatonin as a sperm cryoprotectant in fish species and establish improvement protocols for cryopreservation.

Summary: This study investigated the effect of pulsed light treatment on acerola ripening physiology and quality. The results showed that pulsed light treatment reduced respiration and ethylene production, decreased weight loss, and increased firmness of acerola fruits. It also enhanced antioxidant enzyme activity and polyamine synthesis. Pulsed light treatment preserved the content of vitamin C and polyphenols, delayed the ripening process, and improved fruit quality.
