  1. Prediction of Cadmium Threshold Using Regression Model for Soils Under Cd-Containing Organic Residue Application

    • Thu, 07/07/2022 - 04:00
    • Water, Air, & Soil Pollution
    • Organic residue is a good resource of organic matter and nutrients to improve soil physico-chemical properties, but the toxic trace elements, including cadmium (Cd), borne with it may limit its suitability for arable land. This study aimed to develop regression models for Cd critical concentration in the soils amended with Cd-containing organic residue in view of food safety.

  2. Evaluating the mouse model for estimation of arsenic bioavailability: Comparison of estimates of absolute bioavailability of inorganic arsenic in mouse, humans, and other species

    • Thu, 07/07/2022 - 04:00
    • Journal of Toxicology and Environmental Health, Part A
    • Accurate assessment of adverse health effects attributable to ingestion of inorganic arsenic (As) present in contaminated soils requires determination of the internal dose of metal provided by ingested soil. This calculation requires estimation of the oral bioavailability of soil-borne (As). Animal models to assess the bioavailability of soil (As) are frequently used as surrogates for determination of this variable in humans.

  3. Self-cleaved expression of recombinant lysostaphin from its cellulose binding domain fusion

    • Thu, 07/07/2022 - 04:00
    • Applied Microbiology and Biotechnology
    • Mature lysostaphin (mLst) is a glycineglycine endopeptidase, capable of specifically cleaving penta-glycine crosslinker in the peptidoglycan of Staphylococcus aureus cell wall. It is a very effective therapeutic enzyme to kill the multidrug-resistant S. aureus often encountered in hospital acquired infections. Fusing cellulose binding domain (CBD) to mLst significantly reduced the insoluble expression of mLst in E.

  6. Sodium para-aminosalicylic acid ameliorates lead-induced hippocampal neuronal apoptosis by suppressing the activation of the IP3R-Ca2+-ASK1-p38 signaling pathway

    • Wed, 07/06/2022 - 14:45
    • Ecotoxicology and Environmental Safety
    • Lead (Pb) is a naturally occurring heavy metal, which can damage the brain and affect learning and memory. Sodium para-aminosalicylic acid (PAS-Na), a non-steroidal anti-inflammatory drug, can readily cross the blood-brain barrier. Our previous studies have found that PAS-Na alleviated Pb-induced hippocampal ultrastructural damage and neurodegeneration, but the mechanism has yet to be defined.

  8. Effect of boron on cadmium uptake and expression of Cd transport genes at different growth stages of wheat (Triticum aestivum L.)

    • Tue, 07/05/2022 - 04:00
    • Ecotoxicology and Environmental Safety
    • Boron (B) is an essential microelement for plant growth and has been shown to reduce cadmium (Cd) toxicity in wheat through modulating gene expression. However, there is not enough information about the effects of different applications of B fertilizer on the accumulation of Cd, particularly throughout the wheat growth period. This experiment employed two different B fertilization methods.

  9. PscCYP716A1-Mediated Brassinolide Biosynthesis Increases Cadmium Tolerance and Enrichment in Poplar

    • Tue, 07/05/2022 - 04:00
    • Frontiers in Plant Science
    • Cadmium (Cd), as one of the heavy metals with biological poisonousness, seriously suppresses plant growth and does harm to human health. Hence, phytoremediation was proposed to mitigate the negative effects from Cd and restore contaminated soil. However, the internal mechanisms of detoxification of Cd used in phytoremediation are not completely revealed. In this study, we cloned the cytochrome P450 gene PscCYP716A1 from hybrid poplar “Chuanxiang No.
