Summary: The study found that citrus leaves exposed to lead and copper contamination showed impacts on growth, chlorophyll content, and other factors, demonstrating symptoms of oxidative stress. The treated plants exhibited increased lipid peroxidation, elevated antioxidants, and significantly decreased photosynthetic activity.

Summary: The study investigated the impact of endogenous oxidative stress caused by submicromolar hydrogen peroxide in a mutant strain of E. coli. Through label-free quantitative proteomic analysis, 265 differentially expressed proteins were identified, activating DNA repair and cellular antioxidant signaling pathways. These findings highlight the role of oxidative signaling and the potential of mutant E. coli as a cell model for studying oxidative stress effects.

Summary: This study develops a universal strategy to measure CAT and CAT-like activity, overcoming the limitations of current assays and facilitating insightful studies on applications of CAT and CAT-like nanozymes. The oxygen-sensitive and H2O2-inhibitory self-polymerization of dopamine is demonstrated as an activity indicator for CAT or CAT-like nanozymes. This assay shows allround advantages in sensitivity, specificity, and versatility.

Summary: This study conducted two separate farm experiments to investigate the effects of seed priming or foliar spraying with salicylic acid on Indian mustard plants under drought and well-watered conditions. The results showed that a high dose of clopyralid had adverse physiological and biochemical effects on the plants, but the effects were less severe under drought conditions. Application of salicylic acid, especially seed priming, reduced oxidative stress and lipid peroxidation, and increased leaf chlorophyll, carotenoid, and water content. These findings suggest that salicylic acid has a beneficial impact on detoxifying clopyralid.

Summary: This study aimed to investigate the changes in phytochemical compounds in the leaves of different pomegranate rootstocks under well-watered and drought-stressed conditions. The results showed that some pomegranate rootstocks, such as 'Daneshgah 13' and 'Daneshgah 32', exhibited good tolerance to drought stress. These rootstocks had higher levels of chlorophyll, soluble proteins, proline, total phenol, GPX and CAT enzyme activities, as well as lower levels of MDA and H2O2. Therefore, they can be used to promote pomegranate yield in drought-prone regions and in breeding programs for drought tolerance.

Summary: This research aimed to study the combined effects of water deficit and salt stress on triticale, focusing on various morpho-physiological and biochemical traits. The results showed that salinity and water deficit stress led to decreased yield and plant health, while also increasing oxidative stress and enzyme activity in triticale. The impact was particularly severe during flowering stage, highlighting its sensitivity to the dual stressors.

Summary: The study revealed that during the senescence process of tall fescue leaves, the contents of phytochelatins, glutathione, and non-protein thiols increased, leading to promotion of Cd-binding, which is achieved through the protein degradation pathway.

Summary: The results showed that the number of cut flowers produced per pot and growth traits were significantly increased under 1 mM treatment of SA and 6 g m(-2) treatment of HM compared to control. Physiologically, there was a reduction in ion leakage, malondialdehyde accumulation, hydrogen peroxide accumulation, and an improvement in antioxidant enzyme activity with 1 mM of SA and 4 g m(-2) of HM.

Summary: This study investigates the effects of endogenous polyamines (PAs) on the antioxidant system in alfalfa under drought stress. It was found that high activity of arginine decarboxylase (ADC) and S-adenosylmethionine decarboxylase (SAMDC) promotes the conversion of putrescine (Put) to spermidine (Spd) and spermine (Spm), leading to increased accumulation of Spd and Spm and enhanced drought resistance in alfalfa.

Summary: Soils contaminated with antibiotics can have adverse effects on soil-dwelling animals, as shown in a systematic ecological toxicity assessment of norfloxacin on the soil collembolan Folsomia candida. While norfloxacin had minimal impact on population and individual levels, antioxidant enzyme activities were significantly affected with longer exposure times or higher concentrations. Changes in gut microbiota diversity and composition were limited, but the presence of norfloxacin led to a decrease in operational taxonomic units in the gut and a reduction in the relative abundance of the predominant bacterial genus Wolbachia. Wolbachia may serve as a potential bioindicator for assessing norfloxacin pollution in soils at environmental concentrations.

Summary: This study aimed to investigate the influence of different polyphenolic antioxidant-rich beverages on five-a-side/futsal players. The results showed that oxidative stress markers significantly increased in the blood after the match, while the almond-based beverage supplemented group had significantly lower malondialdehyde levels in neutrophils compared to the control group. In conclusion, polyphenolic antioxidant and anti-inflammatory supplements could aid in optimal recovery after high-intensity futsal games.
