The characteristics of L-proline transport in the procyclic form of Trypanosoma brucei were studied by using L-[14C]proline and a quick separation technique by centrifugation through an oil mixture. L-Proline uptake displayed typical Michaelis-Menten kinetics, with a Km of 19 microM and a maximum transport velocity of 17 nmol/min per 10(8) cells at 27(More)
The nature of reactions catalysed by yeast phosphatidylinositol synthase expressed in E. coli has been investigated. The single enzyme is shown to carry both CDP-diacylglycerol-dependent incorporation of inositol into phosphatidylinositol (Km for inositol of 0.090 mM) and a CDP-diacylglycerol-independent exchange reaction between phosphatidylinositol and(More)
Thirty of 200 cases of lumbar radiculalgia of degenerative origin presented clinical, radiologic, saccographic, and computed tomography signs of a typical narrow lumbar canal, half of these patients having benefited from surgical mobilization of the neuromeninges. Performances of new generation scanners have enabled the development of computed tomography(More)
