Corrosion of carbon steel by Pseudomonas stutzeri CQ-Z5 in simulated oilfield water.

Carbon steel, an important infrastructure material in the petroleum industry, experiences serious damage due to Microbially Influenced Corrosion (MIC) with untold economic impact. Pseudomonas stutzeri CQ-Z5 with solid biofilm formation and organic acid-producing ability was isolated from Changqing oilfield produced water. The corrosion behavior and mechanism of 20 carbon steel by P.

Elevated Level of PINK1/Parkin-Mediated Mitophagy Pathway Involved to the Inhibited Activity of Mitochondrial Superoxide Dismutase in Rat Brains and Primary Hippocampal Neurons Exposed to High Level of Fluoride.

To reveal the molecular mechanism of brain damage induced by chronic fluorosis, expression of PTEN-induced kinase 1 (PINK1)/parkin RBR E3 ubiquitin-protein ligase (Parkin)-mediated mitophagy pathway and activity of mitochondrial superoxide dismutase (SOD) were investigated in rat brains and primary cultured neurons exposed to high level of fluoride. Sprague-Dawley (SD) rats were treated with fluoride (0, 5, 50, and 100 ppm) for 3 and 6 months. The primary neurons were exposed to 0.

Association Between Different Indicators of Obesity and Depression in Adults in Qingdao, China: A Cross-Sectional Study.

This study was designed to investigate the perceived relationship between body weight and depression risk in a Chinese population in Qingdao, China. A population-based cross-sectional survey was performed with 4,573 participants (between 35 and 74 years) from the year 2009 to 2012 in Qingdao, China. We applied the Zung self-rating depression scale to ascertain the level of depression in participants.
