The glycoinositol phospholipid (GIPL) profiles of American Leishmania spp. (L. mexicana and L. braziliensis), Leishmania donovani, and American Trypanosoma spp. (T. cruzi and T. rangeli) were compared. The major GIPLs in these parasites include tetraglycosyl-, pentaglycosyl-, and hexaglycosylphosphatidylinositol. These were partially identified by their(More)
(2005) Changes in mechanical, chemical, and thermal sensitivity of the cornea after topical application of nonsteroidal anti-inflammatory drugs.(2005) Mutations of a conserved lysine residue in the N-terminal domain of alpha7 nicotinic receptors affect binding and gating of nicotinic agonists.(2005) Transient maternal hypothyroxinemia at onset of(More)
The characteristics of the binding sites for ADP and adenylyl imidodiphosphate have been studied in soluble and particulate F1-ATPase from bovine heart mitochondria. ADP, but not electrochemical gradients, removes the inhibitory effect of adenylyl imidodiphosphate on ATPase activity in coupled submitochondrial particles. In soluble F1-ATPase, methanol at(More)
Trans-sialidase catalyzes the transference of sialic acid from host to the Trypanosoma cruzi surface. Here, we characterize the sialic acid acceptors of this protozoan parasite as mucin-like molecules, which are anchored to the membrane by glycosylphosphatidylinositol. The mucins isolated from the insect stages differ from the mucins isolated from the(More)
