Summary: In this study, polystyrene grafted hollow layered double hydroxides (NiCo-LDH@PS) were prepared and used as solid-phase micro-extraction (SPME) coating for the rapid detection of polycyclic aromatic hydrocarbons (PAHs) in combination with high performance liquid chromatography (HPLC). The NiCo-LDH@PS-coated SPME fiber showed enhanced adsorption capacity for seven PAHs and required only a small amount of adsorbent. The study demonstrated the great application potential of the hollow core-shell structured NiCo-LDH@PS as an SPME composite coating in adsorption and separation field.

Summary: A series of 5,6-modified steroidal D-homo lactones, including halogenated and/or oxygenated derivatives, were synthesized and evaluated for potential anticancer properties. The synthesized compounds showed significant cytotoxicity against cancer cell lines, with a 3 beta,5 alpha,6 beta-trihydroxy derivative exhibiting strong cytotoxicity against multiple cell lines. Molecular docking suggested a potential mechanism for cytotoxicity through inhibition of EGFR signaling. Some compounds were found to induce apoptosis in treated cell lines and exhibit affinity for estrogen receptors.

Summary: Highly oxygenated organic molecules (HOM) are important in the formation of secondary organic aerosol (SOA), with the reaction of isoprene with nitrate radical (NO3) leading to the formation of various HOM species, including monomers, dimers, and trimers through peroxy radicals and autoxidation. The study shows that second-generation products, such as 2N-monomers, play a dominant role in HOM formation, with different HOM showing distinct time profiles indicating multiple formation pathways and isomers. Total HOM molar yield in the reaction was estimated to be 1.2% (+1.3%)(-0.7%), suggesting a significant contribution of HOM to SOA yield.

Summary: The study found that dietary supplements containing pure L-ascorbic acid accelerated the oxidation of linseed oil during digestion. On the other hand, supplements containing a mixture of ascorbic acid/salt with citric acid and carotenes, as well as those containing ascorbyl palmitate, protected linseed oil against oxidation and reduced the degradation of gamma-tocopherol.

Summary: A hollow bimetal-organic framework (H-BiMOF) was successfully synthesized and used for the trace extraction of PAHs from environmental samples. The H-BiMOF-coated SPME fiber showed advantages of quick equilibrium and high extraction efficiency. A new method for the determination of PAHs in environmental water samples was established by combining the H-BiMOF-coated SPME fiber with GC-MS/MS. The method exhibited low limits of detection, wide linear range, and good reproducibility, and was validated with real water samples.

Summary: The in vitro digestion process of highly oxidized soybean oil was studied to understand the transformations of oxidized lipids containing potentially toxic compounds. It was found that polyunsaturated group bioaccessibility during digestion was affected by lipolysis and oxidation occurrence. While some oxidation products like epoxy-compounds and hydroxy-compounds persisted or increased, toxic aldehydes decreased during digestion. Additionally, a high ovalbumin proportion in the digestion process reduced oxidation and the concentration of potentially bioaccessible toxic compounds.

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.
