Summary: The endoplasmic reticulum, as the largest cellular organelle, plays a crucial role in protein synthesis, folding, transportation, and maintaining Ca2+ homeostasis. imbalances in its environment can lead to endoplasmic reticulum stress and metabolic diseases. In this study, we developed endoplasmic reticulum-targeting Se-doped carbon nanodots, which were shown to effectively eliminate reactive oxygen species and protect cells from oxidative damage. The carbon nanodots also demonstrated anti-inflammatory effects in mice.

Summary: In this study, a N/Co-co-doped graphite gas diffusion electrode (Co-NG GDE) has been prepared and applied in the E-peroxone system. Surprisingly, Co-NG GDE exhibits the highest degradation efficiency for phenol and oxalate, despite its poor performance in the ORR to H2O2. The abundance of O2(center dot-) produced by Co-NG GDE, due to its higher pyridine-N content, can replace H2O2 to form super-active center dot OH.

Summary: This study aimed to determine the chemical composition and physical characteristics of the step gradient ethanol precipitates of celluclast-assisted hydrolysate from Sargassum thunbergii (STCFs). The yields of STCFs were STCF1 3.78 ± 0.01 %, STCF2 1.13 ± 0.06 %, and STCF3 0.17 ± 0.05 %. Polysaccharide and sulfate contents significantly increased in STCF1 and STCF2 but decreased in STCF3. Their physical characteristics were determined via FTIR, SEM, MALS, and MS. FTIR showed that STCF1 and STCF2 have specific S-O, C-O-S bonds in sulfate, while STCF3 has a specific C-O bond in glucan.

Summary: The study shows that persulfate can enhance the degradation of sulfamethoxazole in a water falling film dielectric barrier discharge plasma reactor, with PMS performing better than PDS. Increasing the applied voltage, solution pH, and PMS/PDS concentration promotes SMX degradation. The reactive species generated from the activation of PMS/PDS by discharge plasma play a key role in SMX degradation, with center dot OH and SO4 center dot- being particularly important.

Summary: Lipid oxidation is a major cause of quality deterioration in meat and meat products, but can be prevented or delayed by antioxidants. In this study, 15 sage extracts were tested for their ability to reduce lipid oxidation in refrigerated pork and beef. The results showed that all 15 sage extracts were effective in reducing lipid oxidation, with variations based on genotype and harvest time. The superoxide anion scavenging activity was found to be the best determinant of sage's ability to reduce lipid oxidation in meat samples among the methods used.

Summary: Solid-liquid interfaces are widely present in nature and have various applications. Electron transfer at the interface has been discovered, and a two-step theory for the formation of solid-liquid electric double layer (EDL) has been proposed. Hydroxyl radical (.OH) is generated at the interface without external interference, and its concentration increases with pH, indicating that it is generated from hydroxide ions (OH-) through electron transfer during contact electrification. The generation of reactive oxygen species (.OH and .O2-) at the interface has potential applications in pollutant degradation.

Summary: An early school start time negatively impacts students' sleep, well-being, and academic performance, but its effect on eating disorders is not well understood. Students with a school start time of 9:00 in Russia tend to wake up later, sleep more, experience less social jetlag and sleep loss, and have higher academic performance compared to those starting school at 8:00. Additionally, the frequency of food addiction is found to be lower in students with a later school start time.

Summary: The adhesion of cross-linked low-methyl esterified pectin hydrogel to rat intestinal serosa was investigated. FeP hydrogel showed higher adhesion than hydrogels cross-linked by Ca2+, Zn2+, and Al3+ cations. The concentration of cross-linking cation did not affect the adhesion of the pectin hydrogel. The mechanical properties and surface microrelief of the hydrogel were influenced by the type and concentration of the cross-linking cations. FeP hydrogel demonstrated better stability and mechanical properties in physiological environments, making it a promising bioadhesive for tissue engineering.

Summary: The study aims to develop and evaluate the printability of k-carrageenan inks enriched with lupin callus tissue and examine their effect on the texture and digestibility of 3D-printed gel. Results showed successful 3D printing of enriched ink at specific concentrations of callus. Higher concentrations of callus material reduced the feasibility of 3D printing. The texture and rheological properties of the gel were influenced by the type and concentration of callus used. Incorporating lupin callus into hydrocolloid ink for food 3D printing could lead to the development of gelling material with new properties.

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: 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.
