Summary: Monoterpenes applied as a foliar spray can increase antioxidant capacity and decrease oxidative stress in tomato plants under water deficit stress. The foliar uptake of exogenous monoterpenes was confirmed by the increase in foliar content with spray concentration. Exogenous monoterpenes effectively decreased the accumulation of hydrogen peroxide and lipid peroxidation. However, their role in preventing reactive oxygen species accumulation rather than mitigating subsequent damage was emphasized. Low spray concentration proved most effective in decreasing oxidative stress, while higher concentrations up-regulated key antioxidant enzymes. The protective properties of specific monoterpenes and endogenous antioxidants require further research.

Summary: This study evaluates markers of oxidative stress in Tunisian asthmatic patients and finds that these markers are correlated with uncontrolled asthma. Asthmatic patients have higher levels of MDA and AOPP, lower levels of GSH and GPx activity, and higher SOD activity. Uncontrolled asthma patients exhibit increased levels of MDA and AOPP and SOD activity, as well as decreased GSH level and GPx activity.

Summary: This study summarized the impact of CoQ10 supplementation on oxidative stress status, showing that it can increase total antioxidant capacity (TAC) and reduce malondialdehyde (MDA) concentrations, especially beneficial for individuals with coronary artery disease or type 2 diabetes, with a dosage of 100-150 mg per day showing better effects.

Summary: This study investigates how A. baumannii regulates catalase activity and oxidative stress phenotypes in response to light. It is found that the BlsA protein is involved in this process by regulating the activity of the KatE enzyme. Furthermore, it is discovered that the interaction between BlsA and protein partners is necessary for the regulation of catalase and superoxide dismutase activities. These findings are important for understanding how A. baumannii uses light as a signal to control its crucial oxidative stress resistance mechanisms that contribute to its pathophysiology.

Summary: This study developed an efficient detection method of penconazole based on ultrahigh performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and investigated the degradation behaviors of penconazole in apple fruit. The results showed that there was no significant difference in penconazole residue after 45 days when the residue was <= 0.2 mg/L. However, penconazole application induced stress, and bagging affected the activity of antioxidant enzymes in apple fruit.

Summary: The gender specificity of clinical and psychopathological features of schizophrenia is important. Researchers are particularly interested in the gender features of cognitive deficit, functional disorder, and structural disorder in schizophrenia. Oxidative stress is considered one of the potential pathogenetic factors associated with gender in schizophrenia. However, there are currently very few studies on gender differences in redox imbalance severity in schizophrenia patients. The aim of this study was to explore the gender specificity of oxidative stress severity in schizophrenia patients and its association with neurocognitive deficit.

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: The study found that the MDA level was elevated in the AD induced group, indicating a poor oxidative stress-defence mechanism. The RS and DPZ treatment groups showed higher SOD activity, suggesting an improved oxidative stress-defence mechanism. The RS + DPZ group exhibited higher SOD activity, indicating a synergistic effect between DPZ and RS.

Summary: This study conducted an experiment on 20 healthy volunteers to investigate the changes in oxidative stress levels after a regular meal. The results showed that levels of malondialdehyde (MDA), total antioxidant capacity (T-AOC), and superoxide dismutase (SOD) increased within 2 hours after the meal, and then decreased with fasting time.

Summary: This paper examines the emergence and symmetry of core-periphery structures in complex networks. By modifying the classic repeated prisoner's dilemma model, the study reveals that players' network strategies drive the formation of core-periphery structures, with the core being symmetric due to interactions among core players.

Summary: This study assessed the perception of ethics among radiographers and radiography students in the Czech Republic. The majority of respondents considered ethics to be important for their profession. Most radiographers had encountered ethical dilemmas, while only a few students had. Almost all were aware of a Code of Ethics for radiographers, and the majority had received ethics education during their professional training. The study findings were different from similar surveys conducted in the USA.

Summary: This paper proposes a new model to explain the emergence and evolution of core and periphery structures in a multilayer network. The model considers the direct costs of maintaining interactions between players and the ability to end disadvantageous interactions. Simulation results show the gradual emergence of a densely connected cooperative core and the isolation of defectors on the periphery.

Summary: The presence of desmoplasia in pancreatic ductal adenocarcinoma (PDAC) is associated with poor treatment outcomes and reduced drug delivery. By analyzing collagen subtypes in PDAC tumors following different treatment regimens, immunofluorescence profiling can predict long-term survival and tumor growth inhibition. This information can aid in personalized treatment and improve patient survival.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
