  • Air Pollution

    Hong et al. (2016) investigated the mechanisms behind how particulate matter, which contains chemicals such as polycyclic aromatic hydrocarbons (PAHs), causes rhinitis. This was an in vitro experiment, but they found that in cells exposed to particulate matter, reactive oxygen species were increased, while superoxide dismutase, catalase, and glutathioneperoxidase were decreased. When the cells were…

  • Glucuronidation and Enterohepatic Recirculation

    β-glucuronidase produced by the microbiome can deconjugate xenobiotics that have already undergone glucuronidation by phase II enzymes, causing them to undergo enterohepatic recirculation rather than being eliminated in the feces.   Elmassry et al. (2021) found that males have higher levels of intestinal β-glucuronidase than females, and infants have higher levels than their mothers.  Malik et…

  • Quercetin

    Among the polyphenol phytochemicals found in blueberries, broccoli, onions, and green tea is the flavonoid quercetin (Li et al., 2021).  Quercetin is also found in apples and grapes (Gugliandolo et al., 2020).  Sanver et al. describe the structure of quercetin in a peer-reviewed primary article; they found that the different structures of different types of…
