    Oxidative stress cytotoxicity induced by platinum-doped magnesia nanoparticles in cancer cells by Mohamed Qasim, Al-Fahdawi

    Published 2021
    “…Pt/MgO nanoparticles were cuboid and in the nanosize range of 30–50 nm. The cytotoxicity of Pt/MgO nanoparticles was determined via the 3-(4,5-dimethylthiazol-2-yl)−2,5-diphenyltetrazolium bromide assay on the human lung and colonic cancer cells (A549 and HT29 respectively) and normal human lung and colonic fibroblasts cells (MRC-5 and CCD-18Co repectively). …”

    Propagation rate coefficient for sulfobetaine monomers by PLP-SEC by Lacík, Igor

    Published 2016
    “…The kp values are determined in aqueous solutions for monomer concentrations between 5 and 50 wt % and temperatures between 15 and 80 °C. The propagation rate for SBE is by about a factor of two higher than that for SBAm. …”

    Harmed Trait Self-Control: Why Do People with a Higher Dispositional Malicious Envy Experience Lower Subjective Wellbeing? A Cross-Sectional Study by Briki W.

    Published 2019
    “…Therefore, the present study is the first to examine the interrelationships between dispositional benign and malicious envy, trait self-control, demographics (i.e., sex and age) and subjective wellbeing. Four hundred six people (234 females and 172 males; M age=32.07, SD age=10.98, from 18 to 71 years old) took part voluntarily in the study and answered questions related to demographics, dispositional envy, trait self-control, and subjective wellbeing. …”

    The Influence of Qatari Dust on the Element Composition of Marine Plankton by Yigiterhan, Oguz

    Published 2021
    “…The excess concentrations relative to average dust from Qatar for most elements (except Cd) decreased with distance from shore. This may be due to contamination or uncertainties with the lithogenic correction or due to our sampling locations in a marginal sea, dominated by dust input. …”

    Spatial, temporal, and demographic patterns in prevalence of chewing tobacco use in 204 countries and territories, 1990-2019: A systematic analysis from the Global Burden of Diseas... by Kendrick, Parkes J

    Published 2021
    “…Prevalence among young people aged 15–19 years was over 10% in seven locations in 2019. Although global age-standardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: –1·21% [–1·26 to –1·16]), similar progress was not observed for chewing tobacco (0·46% [0·13 to 0·79]). …”
