Summary: The interactions between CuII, FeIII, and MnII complexes and free radicals DPPH and ROS were studied using colorimetric and EPR techniques. The results showed that all complexes enhanced the cellular protection against oxidative stress, with higher antioxidant activity observed for CuII and FeIII ions compared to MnII and [Mn(salen)Cl].

Summary: The study found that patients with subclinical hypothyroidism had higher levels of superoxide dismutase and that levothyroxine replacement therapy had positive effects on oxidative stress parameters and lipid profile, including decreasing SOD and catalase levels and increasing HDL-C levels.

Summary: This study found that the combined application of melatonin and salicylic acid can improve the tolerance of Gladiolus grandiflorus to arsenic toxicity. The combined application had a more pronounced effect in alleviating arsenic-induced oxidative stress in plants compared to individual application.

Summary: Sleep deprivation is a widespread issue in modern society, with unclear effects on oxidative stress. This review analyzed experimental data from studies on rat models conducted between 2015 and 2022, and found that sleep deprivation appears to affect oxidative stress parameters, indicating a potential antioxidant role of sleep. The effects of sleep deprivation were observed in different protocols and rat strains, and extended beyond the central nervous system to other body sites. Sleep recovery exhibited variability, with some parameters normalizing and others showing long-lasting changes. The presence of a stress response following sleep deprivation was also noted, but its origin and impact remain unclear.

Summary: This paper proposes a fast method for preparing aqueous graphene oxide dispersions by electrochemical oxidation of a graphite anode without preliminary intercalation with oxidizing agents. Ultrasonic probing in the modulation mode of ultrasonic waves (work/rest) was used for more efficient graphite oxidation-exfoliation. It is shown that the 4/2 s mode of ultrasonic modulation is the most effective in terms of probe material's low corrosion, maintaining optimum synthesis temperature, and achieving the best characteristics of the resulting product.

Summary: This study investigated the effect of hydrogen sulfide on chilling injury of banana during cold storage. The results showed that hydrogen sulfide treatment significantly reduced chilling injury index and increased chlorophyll content in banana fruits. The treated fruits also exhibited improved appearance and quality attributes.

Summary: This study evaluated the effects of the acidulant GdL and drying on the characteristics of boneless dry-cured lamb hams. The use of GdL reduced drying time and increased lactic acid bacteria counts. GdL did not affect water activity, lipid oxidation, and color and texture characteristics, but a higher drying rate resulted in greater hardness and chewiness.

Summary: A practical TLC-direct bioassay method was established for screening and evaluating antioxidant activity. The method involved a series of reactions, including the production of lipid peroxides by UV irradiation of linoleic acid and the conversion of peroxides into malondialdehyde. A dot blot test using TLC separation showed that substances with anti-lipid peroxidation activity appeared as white spots/zones on a red background. The method was validated for selectivity, sensitivity, linearity, precision, and recovery, and was successfully used to identify active antioxidant constituents from Perilla fruits.

Summary: This study investigated the effects of arginine on the postharvest quality of sweet cherry fruits. The results showed that arginine reduced electrolyte leakage, active oxygen production, and lipid peroxidation in the fruits. It also increased the activity of antioxidant enzymes and improved the firmness of the fruits. Furthermore, arginine decreased chilling injury and weight loss, while increasing titratable acid, soluble solids, and vitamin C content in the fruits.

Summary: The study aimed to characterize the oxidative status in healthy equine neonates, evaluating lipid peroxidation and antioxidant systems during the first week of life. Results showed higher GPx activity at 12 and 72 hours, and an increase in TBARS levels at 5 minutes after birth, followed by a decrease at 72 hours and stabilisation until 168 hours after birth.

Summary: This study investigated the association between enzymatic factors in semen, polymorphisms (SOD2 rs4880, GPX1 rs1050450, and CAT rs1001179), and male infertility. The results showed that the rs1050450 polymorphism was associated with a reduced risk of male infertility, asthenozoospermia, and teratozoospermia, while the rs4880 polymorphism was associated with an increased risk of male infertility and teratozoospermia.

Summary: The study evaluated oxidative stress and lesion length in soybean seedlings infected with the fungus Macrophomina phaseolina to determine the most tolerant soybean cultivar. Superoxide anion radical production and superoxide-dismutase (SOD) activity were highest in the Favorit cultivar, indicating its tolerance to M. phaseolina. In contrast, the Victoria cultivar showed high radical production, low SOD activity, and enhanced lipid peroxidation, suggesting its susceptibility to the pathogen. No significant differences were observed in the oxidative stress parameters of the Atlas and Rubin cultivars compared to the control. The Victoria cultivar had the longest lesion length, while the Atlas and Rubin cultivars displayed the shortest lengths, indicating their tolerance to the pathogen.
