In Vitro Activity Of A New Echinocandin, Ly303366, Compared With Those Of Amphotericin B And Fluconazole Against Clinical Yeast Isolates
(Amer Soc Microbiology, 1997)The in vitro activity of LY303366, a new echinocandin derivative, was evaluated with 191 yeast isolates by a broth microdilution method. The MICs at which 50% of the isolates were inhibited were 0.125 mu g/ml for Candida ... -
Composition Of Gamma-Ray Induced Triethoxyvinylsilane Methyl Methacrylate Copolymers Determined By Xps
(Elsevier Sci Ltd, 1998)Methyl methacrylate (MMA) was copolymerized with triethoxyvinylsilane (TEVS) using Co-60-gamma radiation at varying masses of the liquid monomers in the feed. Their homopolymers PMMA and PTEVS were also prepared by the ... -
Uv-Vis, Ir And Xps Analysis Of Uv Induced Changes In Pvc Composites
(Elsevier Science Bv, 1999)PVC undergoes a high degree of dehydrochlorination when exposed to energetic photons. The released HCl (acid), however, can be trapped if a suitable trapping material (base) is also enclosed within the solid matrix as a ... -
Tc-Glutathione Complex (Tc -Gsh) : Labelling, Chemical Characterization and Biodistribution in Rats
(1999)The chemical structure of 99mTc-GSH has been estabilished using the 99Tc isotope. Labeling of glutathione with technetium in the presence of stanous chloride gave a high yield result. In a comparative study between 99Tc ... -
