Summary: Based on data from the RaNCD cohort study, this study found an association between dietary antioxidants and kidney diseases, suggesting that a high total antioxidant capacity in the diet may have a protective effect on renal function but not on the development of kidney stones.

Summary: The sweet chestnut fruit is of great importance in southern European countries due to its economic, environmental, and health benefits. This study investigated the antioxidant activity and chemical composition of different varieties of chestnuts grown in various regions of northwest Spain, and found that climate and geographic factors significantly affect the quality and potential of chestnuts.

Summary: The study found that the polyphenol content and antioxidant capacity of extracts from Hypericum perforatum L. flowers are affected by harvest time, with air-dried extracts showing higher values than lyophilized ones. Different collection dates influenced the composition and antioxidant properties of the extracts, as analyzed by various assays and spectroscopic techniques.

Summary: A simple and sensitive strategy for evaluating the total antioxidant capacity (TAC) in beverages and fruits has been proposed using amino/hydroxyl-functionalized carbon dots (N2H4-CDs) and Fe3+. The fluorescence of N2H4-CDs at 650 nm can be effectively quenched by the formation of a non-fluorescence complex (Fe3+/N2H4-CDs). The strategy eliminates interference in complex biological environments and can analyze typical antioxidants and certain thiol antioxidants.

Summary: This study investigated the effects of continuous 24-hour exposure to mobile communication electromagnetic fields on oxidative stress, apoptosis, and inflammation in the liver of rat fetuses. The results showed that exposure to electromagnetic radiation increased oxidative stress, apoptosis, and inflammation, but before a sensitive developmental stage, the mother may provide protection for the embryos.

Summary: A convenient and sensitive method for TAC assay was proposed based on the absorbance difference of reaction systems between various antioxidants existed in food. The colorimetric sensor showed excellent feasibility in practical application in fruit and vegetable food, providing a new avenue for the establishment of colorimetric biosensors.

Summary: Host-derived probiotics are commonly used in aquaculture, but their decreased numbers and activity during processing and storage hinder their effectiveness. This study found that sodium gluconate can promote the growth of host-derived Bacillus velezensis in the intestinal tract of common carp, leading to improved growth performance and intestinal health.

Summary: This study investigated the effects of dietary glucose oxidase (GOD) and its combination with Bacillus amyloliquefaciens SC06 (BaSC06) on the intestinal microbiota, immune function, and antioxidant capacity of broilers. The results showed that supplementation with GOD alone and in combination with BaSC06 improved the antioxidant capacity, immune function, and intestinal microbiota composition of broilers.

Summary: Anthocyanins, a type of flavonoids, have antioxidant effects and are present in fruits such as blackberries and grapes. This study identified and quantified the anthocyanins in black grape skins and blackberries, and found that they have high antioxidant content, making them potential functional foods or fruit-derived products.

Summary: This study analyzed the total dietary antioxidant capacity (TAOX), seasonal variability, and sources in the daily diets of cardiovascular disease (CVD) patients. The primary sources of antioxidants in CVD patients' diets were drinks, fruits, vegetables, and black tea. TAOX significantly depended on the season, with the highest in summer and lowest in spring. This suggests that the antioxidant capacity of CVD patients' diets may fluctuate between seasons, and dietary recommendations should be modified accordingly.

Summary: In this study, the SNPAC method was developed using hypochlorous (ClO-) at pH 9.3 with Polyvinylpyrrolidone (PVP) as a stabilizer. The method achieved lower LOD and LOQ values by the reoxidation of silver atoms with ClO- ions in the presence of PVP. The modified method was applied to measure the total antioxidant capacity (TAC) of Boswellia Serrata, Aronia Melanocarpa tea, and juice with comparable results to CUPRAC and FRAP assays.
