  1. Ionizable copolymer functionalized magnetic nanocomposite as an adsorbent for boosting the extraction selectivity of aristolochic acids

    • Journal of Food and Drug Analysis
    • Aristolochic acid nephropathy (AAN) has drawn increasing public attention. Organic anion transporters (OATs) are considered to be responsible for mediating nephrotoxicity of aristolochic acids (AAs), as AAs are typical OAT1 substrates that exhibit anionic properties and contain one hydrophobic domain.

  2. The Effects of T-2 Toxin, Deoxynivalenol, and Fumonisin B1 on Oxidative Stress-Related Genes in the Kidneys of Laying Hens

    • Toxins
    • In the context of nephrotoxic risks associated with environmental contaminants, this study focused on the impact of mycotoxin exposure on the renal health of laying hens, with particular attention to oxidative stress pathways. Sixty laying hens were assigned to three groups—a control group (CON), a low-dose mycotoxin group (LOW), and a high-dose mycotoxin group (HIGH)—and monitored for 72 h.

  3. The effect of food processing on the bioaccessibility of cadmium and micronutrients from whole wheat porridge

    • Cereal Chemistry
    • Abstract Background and Objectives Wheat porridge contributes to the intake of micronutrients but can also be a route of the toxic heavy metal, cadmium. This study aimed to determine the effect of processing on micronutrients, cadmium dialyzability, and cellular bioaccessibility. Findings Cadmium (0.21%), magnesium (0.19%), iron (0.17%), and zinc (0.07%) presented low bioaccessibility from raw whole wheat flour.

  22. Development and validation of a random forest algorithm for source attribution of animal and human Salmonella Typhimurium and monophasic variants of S. Typhimurium isolates in England and Wales utilising whole genome sequencing data

    • Frontiers in Microbiology
    • Source attribution has traditionally involved combining epidemiological data with different pathogen characterisation methods, including 7-gene multi locus sequence typing (MLST) or serotyping, however, these approaches have limited resolution. In contrast, whole genome sequencing data provide an overview of the whole genome that can be used by attribution algorithms. Here, we applied a random forest (RF) algorithm to predict the primary sources of human clinical Salmonella Typhimurium (S.
