Interspecies sensitivity to the same chemical can be several orders of magnitude different. Quantifying toxicologically internal levels and toxicokinetic (TK) parameters is critical in elucidating interspecies sensitivity. Herein, a two-compartmental TK model was constructed characterize uptake, distribution, elimination kinetics toward an insecticide, imidacloprid. Imidacloprid exhibited highest lethality insect Chironomus dilutus, followed by Lumbriculus variegatus, Hyalella azteca,...

Hepatocellular carcinoma (HCC) is a primary liver cancer with high incidence and mortality. miR-185, microRNA appriximately 22-28 nucleotides, was reported to be involved in many cancers. The potential mechanism of miR-185 on HCC through cell division cycle 42 (CDC42) investigated. RT-qPCR used measure the RNA level CDC42 tissues cells. dual luciferase reporter assay verify whether target gene for miR-185. Transwell employed detect ability migration invasion change expression low negatively...

To estimate the unintentional poisoning burden and risk factors in China from 1990 to 2015.We extracted data Global Burden of Disease Study 2015 compare mortality, prevalence, disability-adjusted life years (DALYs), lost, lived with a disability, China. We determined median percent change 95% uncertainty interval for period between 2015.The age-standardized death rate decreased by 61.8% (4.1 per 100 000) (1.6 000). The prevalence (87.9 2010 (39.0 000), but rebounded (42.6 All combined...
