Hesperetin activated SIRT1 neutralizes cadmium effects on the early bovine embryo development.

Cadmium (Cd) is a major environmental contaminant that has been linked to oocyte quality reduction and early embryo mortality in various in vivo studies. In this study, we investigated the mechanism of Cd-induced mitochondrial toxicity in bovine in vitro matured oocytes, primary cultured bovine cumulus cells, and in vitro developed bovine embryos. Cd significantly reduced PPARGC1A (PGC-1α) and nuclear respiratory factors, which leads to mitochondrial damage and hence reduction in oocyte maturation and embryo development.

A decade of machine learning-based predictive models for human pharmacokinetics: Advances and challenges.

Traditionally, in vitro and in vivo methods are useful for estimating human pharmacokinetics (PK) parameters; however, it is impractical to perform these complex and expensive experiments on a large number of compounds.
