Summary: Nanozymes, nanomaterials with enzyme-mimicking activity, have attracted significant interest in biomedical applications, particularly in oxidative stress-mediated disorders. The challenge lies in designing nanozymes that can selectively differentiate between physiological oxidative stress and pathological oxidative stress and mediate appropriate redox reactions in cells, tissues, and organs. This review summarizes the advancements in redox-active nanozymes and their therapeutic significance in various disease models, such as cancer, neurodegeneration, and cardiovascular diseases. It also discusses the future prospects and challenges associated with the biomedical applications of nanozymes.

Summary: Recent studies have found that salicylic acid (SA) can reduce postharvest losses in various flower systems. This study focused on the role of SA in enhancing physiological and biochemical responses to mitigate postharvest senescence in cut spikes of Consolida ajacis. The results showed that SA treatment increased the postharvest longevity of the cut spikes, as well as the solution uptake, sugar, and protein content of the tepal tissues. SA also enhanced the antioxidant system and reduced lipoxygenase activity, preserving membrane integrity and preventing solute leakage from the tepal tissues.

Summary: Temperature and salinity can impact the physiological responses of aquaculture species. European sea bass and milkfish, farmed in Europe and Southeast Asia respectively, showed increased hepatic antioxidant enzyme activity in response to temperature challenges combined with hypo-osmotic stress over a four-week period. Despite differences in expression profiles, both species exhibited enhanced antioxidant responses under the conditions of the study.

Summary: Reactive oxygen species (ROS) are important in physiological processes but can pose a threat to health with increased concentrations. Different defense systems in plants, invertebrates, and vertebrates including humans combat ROS, but environmental conditions and lifestyle can interfere with enzyme activity. Therefore, finding alternative ROS scavengers is crucial, with nanozymes being a proposed solution to mimic essential enzyme activities and prevent excessive ROS activity.

Summary: The study found that protein concentrations were significantly higher in Bruguiera gymnorrhiza, Kandelia obovata, and Rhizophora stylosa under heavy metal stress conditions, while Avicennia marina had remarkably high MDA content. Superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) levels were significantly elevated in A. marina, A. corniculatum, and B. gymnorrhiza. Principal component analysis indicated that POD, SOD, and MDA were major indices for response to heavy metal stress, with A. marina demonstrating higher tolerance compared to other species.

Summary: Reactive oxygen species (ROS) are byproducts of oxygen metabolism that can damage cellular constituents and exhibit antimicrobial activities. Leptospira, a genus of bacteria, is well-equipped to sustain the oxidative stress encountered inside their hosts during infection. In this review, we discuss the ROS encountered by Leptospira in different ecological niches, defense mechanisms to scavenge ROS, and recent advances in understanding Leptospira's adaptation to oxidative stress.

Summary: This study investigated the changes in antioxidation ability of yellowfin tuna under different salinity environments and found that low salinity may influence the antioxidant function of yellowfin tuna. However, yellowfin tuna juveniles have strong adaptability to a salinity of 29 parts per thousand. Nevertheless, excessive stress may deplete the body's reserves and reduce its resistance.

Summary: This study investigated the nutrient requirements and effects of fertilization on the soil properties and growth status of Erythropalum scandens seedlings through a series of pot experiments. The results revealed that E. scandens seedlings have a stronger sensitivity to nitrogen levels, and excessive fertilization can lead to soil acidification. Proper fertilization treatments can promote better growth status of the seedlings.

Summary: The effect of nitrogen splitting and different irrigation conditions on agronomic and physiological traits of corn was examined. Drought stress resulted in decreased yield, increased proline and abscisic acid contents. The Maxima cultivar exhibited higher resistance to drought stress. Single cross 704 cultivar showed better adaptability to drought stress and nitrogen deficiency.

Summary: The study examined the effects of growth media made of peat and different domestic materials on tomato nutrition, growth, and yield as an alternative to cocopeat in Turkiye. It was found that using vermicompost and its mixtures with peat as growth media resulted in the highest leaf and fruit nutrient concentrations. The highest fruit yields and biomass weights were obtained with solely peat and 1:1 peat + vermicompost medium. Peat-containing growth media, especially peat + vermicompost mixtures, can be used as alternatives to cocopeat in soilless tomato cultivation.
