Summary: This study reports a facile and green strategy of fabricating catkin-like CuAg nanocomposites using tea-polyphenols as the reduction agent. The nanocomposites exhibit a catkin-like special morphology as characterized by physical characterizations. The electrochemical detection hydrogen peroxide (H2O2) results demonstrate the good sensitivity, stability, and anti-interference of the catkin-like CuAg nanocomposites, which can detect H2O2 without any additional mediator or enzyme.

Summary: Oat milk tea can curdle when mixed with tea, affecting consumer acceptability. This study investigated the stability and polyphenol bioaccessibility of oat milk tea model systems. The addition of green tea extract influenced stability, with higher fat content resulting in greater stability. Tea polyphenols were stable in oral and stomach digestion stages but degraded in the small intestine stage. The bioaccessibility of tea polyphenols was higher in high-fat oat milk tea models, especially at low green tea extract concentrations.

Summary: This review evaluates the published effects of green tea polyphenols (GTP) on genotoxic damage induced by metals with carcinogenic potential. It discusses the relationship between GTP and the antioxidant defense system, and examines the processes involved in oxidative stress generated by metals and its relationship to oxidative DNA damage. The review demonstrates that GTP generally decreases oxidative DNA damage induced by exposure to metals and suggests potential use of GTP for preventing and treating oxidative damage in populations exposed to metals.

Summary: Green tea can influence gut microbiota by either stimulating the growth of specific species or hindering the development of detrimental ones, benefiting health through beneficial bacteria or microbial bioactive metabolites. The inter-relation between green tea and gut microbiota is crucial for many health promoting effects of green tea, with the ability to correct microbial dysbiosis in conditions like obesity or cancer. Tea compounds influence the growth of bacterial species involved in inflammatory processes, potentially impacting the development of chronic diseases.

Summary: The study characterized the physical-chemical, antioxidant, and enzymatic properties of green tea and kombucha. Kombucha had lower pH, higher acidity, and solids content compared to green tea. Both green tea and kombucha showed significant antioxidant capacity. While both beverages showed a significant reduction in lipid peroxidation in the neutralized pH TBARS analysis, kombucha exhibited pro-oxidant activity in its natural form. Both beverages also showed significant inhibitory activity of the alpha-glucosidase enzyme, with green tea presenting superior inhibitory potential.

Summary: A facile and rapid fluorescence sensor array based on Tb(III) and Eu(III) doped Zr(IV) metal-organic frameworks was proposed for discriminating Chinese green tea. The large porosity of Tb@UiO-66-(COOH)2 and Eu@UiO-66-(COOH)2 allowed the coordination of phenolic hydroxyl groups of tea polyphenols with free carboxylic acid groups inside the pores, leading to the fluorescence quenching effect. Through Hierarchy Cluster Analysis and Linear Discrimination Analysis, the fluorescence sensor array successfully classified tea polyphenols and discriminated different categories and grades of green tea samples.

Summary: Mood disorders caused by chemotherapy have become more important as cancer patients' survival increases. This study used methotrexate to induce mood disorders in rats and found that treatment with the antioxidant N-acetylcysteine (NAC) can alleviate anxiety and depression-like behaviors, increase antioxidant capacity, reduce oxidative stress and inflammatory response, and regulate brain chemistry. The findings suggest that NAC treatment could be an effective strategy in revising the treatment for individuals suffering from chemotherapy-induced mood disorders.

Summary: This study systematically investigated the effects of extremely low intensity HF-rTMS on cognition in mice and found that 40 Hz rTMS significantly impaired exploratory behavior and spatial memory at both 10 mT and 1 mT conditions. Additionally, 40 Hz stimulation had remarkably different effects on exploratory behavior depending on intensity, compared to 10 Hz stimulation.

Summary: This study examined the efficacy of tDCS for PTSD and related symptoms, as well as the factors that may predict response to tDCS. The results showed that tDCS had a positive effect in reducing symptoms of PTSD, depression, anxiety, and anhedonia. The severity of symptoms at baseline may also predict the response to tDCS.

Summary: Aggression can have serious consequences, but little is known about its personality and neurological origins in children. This study investigated the relationship between self-esteem, aggression, and brain structure in healthy children, and found that self-esteem was negatively associated with aggression. The study also revealed that increased cortical thickness in certain brain areas may be a potential mechanism linking low self-esteem to aggression in children.

Summary: Food deprivation can lead to neurological dysfunctions, including memory impairment. This study used Aplysia as an animal model to investigate the memory deficits caused by prolonged food deprivation. The results showed that 14 days of food deprivation decreased the level of 5-HT in the hemolymph, which contributed to the lack of sensitization and its cellular correlates. However, exogenous application of 5-HT partially induced sensitization in the food deprived animals.

Summary: The study found that intervention with the dual orexin receptor antagonist suvorexant did not have the expected effects on extinction memory and sleep. Higher percentages of REM sleep were associated with poorer extinction memory recall and stronger fear responses. Additionally, the fear extinction training protocol used in this study did not lead to complete fear extinction.

Summary: In this study, a systematic assessment indicator was developed to objectively evaluate hindlimb motor function recovery in rats after thoracic contusion SCI. By screening CatWalk XT gait parameters and using exploratory factor analysis, 38 suitable parameters for assessing motor function were identified. A reliable Coordinated Function Index (CFI) was proposed based on these parameters and simplified for improved assessment efficacy.
