  • This study in Ahmedabad in Gujarat State, India, evaluated the diagnostic performance of a rapid diagnostic test for malaria (SD Bioline Malaria Ag P.f/Pan) versus blood smear examination as the gold standard. (who.int)
  • Facility (GDF), the Roll Back Malaria (RBM) initiative and the Abuja Declarations provide opportunities for increasing coverage and access to the interventions for these diseases. (who.int)
  • 973,492 and 398,118 (compared with 8.25 for CQ) showed similar potency in CQ-S and CQ-R. Importance of LAR for potency against CQ-R parasites probably reflects ability to block efflux by hydrophobic interaction with PfCRT but may relate to beta-haematin inhibition in vacuolar lipid. (nih.gov)
  • However, analyses of isogenic parasite lines bearing different forms of PfCRT in this study revealed lower GSH levels and higher susceptibility to inhibition of GSH biosynthesis in the CQ resistant lines. (gla.ac.uk)
  • The findings of this study suggest that in parasites bearing mutant PfCRT, GSH is transported into the digestive vacuole where it is able to contribute to resistance by degrading heme, before the tripeptide itself is degraded by peptidases inside the vacuole, consistent with the overall reduction of GSH levels in CQ resistant parasites.
