Summary: The team synthesized PMAO-KI NPs that can slowly release iodide into cancer cells, enhancing the production of reactive oxygen species induced by radiation therapy. This promotes radiotherapy against breast cancer by causing DNA damage and lipid peroxidation in cancer cells, ultimately leading to tumor eradication in 80% of treated animals without additional toxicity.

Summary: The study found that adding potassium iodide and sodium selenate separately or simultaneously to the nutrient solution in a floating system and aeroponics increased the content of iodine and selenium in lettuce leaves without any negative effects on plant growth. Post-harvest quality of leaves was also not affected by the treatments.

Summary: In this study, a magnetic cation-exchange resin (MCER) was used for the first time to extract and purify heterocyclic aromatic amines (HAAs) in food samples. The MCER showed superparamagnetism and successfully enriched HAAs from food samples with excellent linearities, low detection limits, and satisfactory precisions and recoveries. Compared with traditional solid-phase extraction, the magnetic solid-phase microextraction method using MCER has the advantages of simpler sample processing and lower cost. The established method was successfully applied to determine HAAs in fried foods under different frying conditions and the concentration of HAAs was influenced by the processing methods, processing time, and frying temperatures.

Summary: This study investigates the effects of sodium (Na) and potassium (K), two common constituents of natural fluids, on dolomite formation rate, stoichiometry, and crystallographic characteristics through high-temperature (215°C) dolomitization experiments. The results show that Na solutions, and to a lesser extent K solutions, are correlated with faster reaction rates and higher stoichiometry in dolomite formation. Moreover, Na at hypersaline fluid concentrations results in dolomites with higher micro-strain and lower cation ordering. On the other hand, potassium affects dolomite differently than sodium, leading to smaller unit cell parameters instead of micro-strain. The study also suggests implications for natural dolomites, including the explanation of why dolomite is more abundant and stoichiometric in evaporative settings with higher concentrations of Na and K in evaporative fluids. It challenges the prediction of the mixing zone dolomitization model and suggests that higher Na and K concentrations actually increase dolomitization rate and stoichiometry. The decrease in dolomite cation ordering with increasing Na and K concentrations implies less stable dolomite in evaporative fluids, which may be more prone to subsequent recrystallization and resetting of primary geochemical signatures.

Summary: Primary aromatic amines derived carbon dots with high quantum yield and protonated amino groups were synthesized through solvothermal treatment. The interaction between the carbon dots and nitrite exhibited strong fluorescence quenching, absorption variation, and chromogenic reaction. These carbon dots were developed into an optical dual-mode and smartphone imaging sensor for selective and sensitive NO2- detection.

Summary: Chlorophyll is responsible for the green color of plant leaves and can be consumed through green vegetables. Metallo-chlorophyll derivatives have the ability to deliver essential metals and bind toxins, primarily during digestion. There are still gaps in understanding the metabolism and bioactivity of metal and toxin-binding properties of this family of molecules.

Summary: This study examined the prescription patterns of SPS/CPS and their impact on RAASi treatment in patients with CKD after an episode of hyperkalemia. The results showed a low frequency of SPS/CPS prescription after hyperkalemia, with RAASi discontinuation or down-titration being the most common approach. New options for managing hyperkalemia in this population are needed.

Summary: This study examined the effects of three widely used food-grade preservatives on gut microbiota diversity and composition in a mouse model. It revealed that different preservatives induce specific patterns of microbial diversity and affect the abundance of certain bacterial taxa. Improved understanding of how food-grade preservatives influence gut microbiota composition and diversity could facilitate prospective studies on diet-microbiome interactions in relation to intestinal and metabolic health.

Summary: This study investigated the biochemical effects of three commonly used food preservatives on Saccharomyces cerevisiae. The results revealed that these preservatives significantly inhibited yeast cell proliferation and metabolic activity, leading to lipid peroxidation. Principal component analysis showed clear differences in biochemical features between the food additive treated groups and the control group.

Summary: The article provides an overview of two main approaches to enhance reactivity in alkaline earth metal catalysis, either through the use of highly dipolar haloaryls as solvents or by increasing the solubility of ligand systems. The resulting coordination modes, reactivities, synthetic strategies, and the latest results of group 1 complex chemistry in aliphatic solvents are presented, with future challenges highlighted.

Summary: Since their discovery, relaxor ferroelectrics have been of great interest due to their unique properties, which are attributed to nanodomains or PNRs. Understanding relaxor properties requires nano-scale or even atomic-scale structural analysis. However, the atomic-scale nanodomain structure is not yet fully understood. In this study, cation displacement and octahedral tilt in Bi0.5Na0.5TiO3 were investigated using aberration-corrected STEM images. The results showed that the cation displacement and octahedral tilt are related and contribute to the formation of nanodomains and relaxor properties. The observation of oxygen octahedral displacement stemming from complex coordinating environments provides further insights into the nanodomain structure.

Summary: Solid polymer electrolytes (SPEs) are the best choice to replace liquid electrolytes in various energy storage devices, but their ionic conductivity and thermal stability still need to be improved. In this study, PVA/salt based SPEs were fabricated using different methods and the effect of different salts and their concentrations on the ionic conductivity was investigated. The results showed that the addition of NaCl, KCl and KI salts significantly increased the ionic conductivity, and electro-spun NaCl SPEs exhibited higher conductivity compared to casted SPEs.

Summary: This study demonstrated the use of azide intramolecular rearrangement as an effective synthetic route for creating valuable heterocyclic amines. Through computational and experimental studies, it was found that the reaction proceeds via a concerted transition state with nitrogen elimination and alkyl/aryl migration occurring simultaneously. The reaction was predicted to be a selective process with migratory aptitude increasing in a row alkyl.
