Summary: The study found that the application of trans-resveratrol and trans-piceid can enhance Arabidopsis thaliana plants' tolerance to UV-B, increasing leaf survival rates. This improvement in tolerance is more effective than using precursors but slightly less effective than using a UV-B absorber. Furthermore, trans-resveratrol also increased the expression of antioxidant and stress-inducible genes.

Summary: The shelf life of peanuts is determined by their susceptibility to lipid oxidation. This study aimed to accelerate the oxidation process using UV radiation. Results showed that after 3 days of UV irradiation, the oxidation process had just started as indicated by the tocopherol content. Furthermore, the aldehydes content increased significantly after 3 and 7 days of UV irradiation.

Summary: Light and ultrasound were used to activate peracetic acid (PAA) for oxidizing bisphenols (BPs). UV irradiation with a wavelength of 254 nm was found to be the optimal activator for PAA based on the chemometric approach. The effectiveness of the UV/PAA system was compared with other oxidation methods, and under optimal conditions, the tested BPs were completely degraded within 15-60 minutes. Toxicity assessment showed that the reaction mixture had limited toxicity towards living organisms.

Summary: In this study, several analogues of RSV were synthesized and their toxicities on neuronal cells were evaluated. The results showed that all analogues had IC50 values between 11.3 and 25 micrograms/mL, while RSV had an IC50 value of 14.5 micrograms/mL. These analogues induced an increase in plasma membrane permeability, mitochondrial depolarization, and overproduction of reactive oxygen species. However, only RSV induced cell death by apoptosis. These analogues may serve as potential alternatives for tumor therapy, but their mechanisms of action differ from RSV.

Summary: This study investigated the effect of different elicitors on the biosynthesis of resveratrol in Alternaria sp. MG1 and found that UV radiation and co-culture with Phomopsis sp. XP-8 significantly promoted resveratrol production. Co-culture altered the profiles of secondary metabolites in MG1 and led to the generation of new flavonoids. Oligomeric proanthocyanidins (OPC) also showed a positive influence on resveratrol production.

Summary: The study explores the effect of light radiation on stilbene induction and ROS metabolism of peanut sprouts, finding that different types of light sources can significantly promote stilbenes and antioxidants in peanuts during germination. Specifically, UV-C radiation can effectively increase the contents of stilbenes and antioxidants in peanut sprouts by mediating the homeostasis of oxidant-antioxidant balance.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: Chitosan-pectin emulsion-filled hydrogel (EFH) was developed to enhance the bioaccessibility of lipophilic bioactive compounds through intestinal delivery. The EFH, prepared without crosslinking agents, demonstrated improved mechanical strength and compactness with higher pectin concentration. It retained the emulsion at pH 2.0 and released it at pH 7.4, resulting in enhanced release of free fatty acids and improved bioaccessibility of curcumin.

Summary: Horse's milk, with its high nutritional value and low allergenic proteins, could be a substitute for cow's milk in infant consumption. A proteomic method was used to identify and compare milk fat globule membrane (MFGM) and whey proteins from different horse breeds. The study found differences in protein composition and functionality, which could support the development of formulas more suitable for human infants.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
