  • From NADH:quinone oxidoreductase enzyme (PfNDAH2) assay, nepodin exhibited significant IC50 values that were 0.74 ± 0.07 and 0.79 ± 0.06 μg/ml against P. falciparum chloroquine-sensitive (3D7) and P. falciparum chloroquine-resistant (S20), respectively. (nih.gov)
  • On the other hand, the long-term therapeutic effects of Radix Paeoniae Rubra extract in the context of T2D remain unclear. (hindawi.com)
  • The lowest DBP doses (1 and 10 mg/kg) did not produce significant effects on Leydig cell ultrastructure, whereas, at the highest doses (200 and 400 mg/kg), the Leydig cells were remarkably conspicuous in the interstitium and appeared foamy. (bvsalud.org)
  • The enzyme then sends these electrons along in a flowing stream to generate a current. (livescience.com)
  • If we immobilize Huc on an electrode, the electrons can enter an electrical circuit from the enzyme surface and generate current. (livescience.com)
  • Entry into the beta-oxidation cycle requires the action of acyl-CoA dehydrogenase, the first enzyme in the sequence, which removes electrons from the alpha-carbon and the beta-carbon, introducing a double bond. (medscape.com)
  • Like all catalysts, enzymes work to lower the activation energy of a reaction, or the initial energy input necessary for most chemical reactions to occur. (newworldencyclopedia.org)
  • This region, where the binding of the substrate(s) and the reaction occur, is known as the active site of the enzyme. (newworldencyclopedia.org)
  • Studies show that persistent pericarditis triggers an autoimmune reaction to the myopericardial cells. (medscape.com)
