Aquaporins (AQP) were originally regarded as plasma membrane channels that are freely permeated by water or small uncharged solutes but not by ions. Unlike other aquaporins, AQP6 overexpressed in Xenopus laevis oocytes was previously found to exhibit Hg2+ or pH-activated ion conductance. AQP6 could not be analyzed electrophysiologically in mammalian cells,(More)
BACKGROUND INFORMATION Most AQPs (aquaporins) function at the plasma membrane, however AQP6 is exclusively localized to membranes of intracellular vesicles in acid-secreting type-A intercalated cells of renal collecting ducts. The intracellular distribution indicates that AQP6 has a function distinct from trans-epithelial water movement. RESULTS We show(More)
The phospholipid metabolism of Plasmodium falciparum-infected erythrocytes has been shown to be an effective pharmacological target for novel chemotherapy. Thirty-seven monoquaternary ammonium derivatives analogous to choline were screened for their potential antiprotozoal activity against P. falciparum and Leishmania braziliensis. Twenty-three compounds(More)
To achieve what I believe to be an acceptable. Information Management System, I propose that a set-theoretic view of a data-base be adopted. Most potential data-base users use the language of set-theory in their day to day references to the objects and relationships of their data-bases. Instead of twisting these natural language references to(More)
