          Journal of Food Safety
          Schematic illustration of PO combined with NFT inhibiting browning and maintaing qualities of fresh‐cut nectarines. Abstract Fresh‐cut fruits were convenient for consumers but vulnerable to quality deterioration, including browning, softening, and volatile aroma loss. In this study, the whole nectarines were pretreated with 100% O2 (pure oxygen, PO) for 2 h and stored at near‐freezing temperature (NFT, −1.5 ± 0.1°C) for 9 days after cutting.

          World Journal of Microbiology and Biotechnology
          The aim of this study was to investigate the mechanisms by which yeasts (*Saccharomyces cerevisiae)* control the toxic effects of aflatoxins, which are not yet fully understood. Radiolabeled aflatoxin B1 (AFB13H) was administered by gavage to Wistar rats fed with aflatoxin (AflDiet) and aflatoxin supplemented with active dehydrated yeast Y904 (AflDiet + Yeast). The distribution of AFB13H and its metabolites were analyzed at 24, 48 and 72 h by tracking back of the radioactivity.

          Food Chemistry
          The escalating use of pesticides on fruits and vegetables has raised concerns about potential health risks. Therefore, we developed a superhydrophilic resin/graphene oxide (SR/GO) with rich adsorption interactions using an eco-friendly synthetic approach. SR/GO demonstrated excellent hydrophilicity, ensuring optimal contact with aqueous sample matrices.

          Abstract Background Grape peels, the main by‐products of wine processing, are rich in bioactive ingredients of phenolics, including proanthocyanidins, flavonoids and anthocyanins. Phenolics have the function of regulating intestinal microbiota and promoting intestinal health. From the perspective of the dietary nutrition of grape peel phenolics (GPP), this study was to investigate the influence of GPP on the composition and metabolism of human gut microbiota during in vitro fermentation.

          PurposePet guardians are increasingly seeking vegan dog foods. However, research on the impact of these diets on gastrointestinal (GI) physiology and health is limited. In humans, vegan diets modify the GI microbiota, increasing beneficial digestive microorganisms. This study aimed to examine the canine fecal microbiota in response to a vegan diet compared to an animal-based diet.MethodsSixty-one client-owned healthy adult dogs completed a randomized, double-blinded longitudinal study.

          Frontiers in Microbiology
          IntroductionControl of Campylobacter from farm to fork is challenging due to the frequent emergence of antimicrobial-resistant isolates. Furthermore, poultry production systems are known reservoirs of Campylobacter. The twin-arginine translocation (Tat) pathway is a crucial bacterial secretion system that allows Campylobacter to colonize the host intestinal tract by using formate as the main source of energy.

          Frontiers in Microbiology
          Escherichia coli (E. coli) is closely associated with the occurrence of puerperal metritis in dairy cows. E. coli carries some the virulence and multi-drug resistant genes, which pose a serious threat to the health of postpartum cows. In this study, E. coli was isolated and identified from the uterine contents of postpartum cows with puerperal metritis in the Ningxia region of China, and its phylogenetic subgroups were determined. Meanwhile, virulence and drug resistance genes carried by E.

          According to the state of the art, most of the mixed copper and copper alloy scrap and residues are processed in a copper smelter. Despite the environmental and economic advantages relative to primary production, the recycling of copper and its alloying elements (zinc, tin, lead, nickel, etc.) requires significantly more energy and cost than remelting unmixed or pure scrap fractions such as separate collected material or production scrap.

          Phytoextraction is an effective technique for removing cadmium (Cd) from contaminated farmland, thus achieving real ecological restoration. To clarify the potential of peanut phytoextraction, we designed a pot experiment to assess the Cd accumulation in peanut. In addition, the contribution of rhizosphere microorganisms in Cd accumulation was explored.
