  • Mitochondrial Dysfunction and Type 2 Diabetes: Mechanisms, Markers, and Interventions

    Type 2 diabetes can be assessed from the perspective of mitochondrial dysfunction as not just a side effect, but a factor in its progression. Symptoms like fatigue and difficulty concentrating can be a sign that mitochondria aren’t functioning properly, and that same underlying dysfunction may be feeding the disease process itself. When mitochondria are impaired,…

  • 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…
