Tea Artemisia annua inhibits Plasmodium falciparum isolates collected in Pikine, Senegal

  Malaria is a major scourge of most countries in Africa which continues to defy science and technology. Several medicinal plants are traditionally used for the treatment of malaria and other protozoa infections. We aimed to assess by the Double-site Enzyme-linked Lactate dehydrogenase enzyme Immuno-detection (DELI) test for the first time in Senegal, Plasmodium falciparum isolates in...

Association of SOD2 gene polymorphism with noise induced hearing loss in textile industry employees

  Noise exposure leads to hearing loss in industrial workers due to release of superoxide anions which damage cochlear epithelium in the ear. These free radicals are regulated by superoxide dismutase 2 (SOD2) and polymorphism in this gene may abet in predisposition to noise induced hearing loss (NIHL). The current study describes prevalence of polymorphism at two different loci...

Changes in the tissue antioxidant enzyme activities of palm weevil (Rynchophorous phoenicis) larva by the action of 2, 2-dichlorovinyl dimethyl phosphate

  The aim of this study was to determine the changes caused by the action of 2,2-dichlorovinyl dimethylphosphate (DDVP) on the three tissues, fat body (FB), gut (GT) and head (H), and the  antioxidant enzymes of African black palm weevil, Rynchophorous phoenicis (Coleoptera: Curculionidae) larva. Larvae of R. phoenics were injected with varied concentrations (0 to 0.66 µg...
