In continuation of our interest in phytochemical screening of the Egyptian flora for potential drugs, the reinvestigation of the methanolic extract of the roots of Solanum diphyllum, which grows naturally in the south of Egypt and is recorded as new to the Egyptian flora, afforded an interesting, highly cytotoxic compound, named 3-O-(beta-D-glucopyranosyl) etioline [(25S)-22,26-epimino-3beta-(b...

Abstract The aim this work was the reinvestigation of phase equilibria in Bi-Te system. as-cast and long-time equilibrated alloys binary system were analysed by scanning electron microscopy, X-ray diffraction (XRD) differential thermal analysis (DTA) methods. primary solidified phases identified for samples. existence four intermetallic phases: Bi 2 Te 3 , BiTe, Te, 7 confirmed. Three them melt...

LITTLE was known about the metabolism of articular cartilage till 1936, when Bywaters1 published the first quantitative data on the subject. He reported a well-defined glucolysis, equivalent per cell to that of other adult tissues, but was unable to demonstrate an appreciable utilization of oxygen. It seemed improbable that a tissue without any respiratory ability could synthesise the complex c...
