17 Antimony-based drugs are still the mainstay of chemotherapy against Leishmania infections in 18 many endemic countries. Efficacy of antimonials has been compromised by increasing numbers of 19 resistant infections, the basis of which is not fully understood and likely involves multiple factors. 20 By using a functional cloning strategy he have recently identified a novel antimony resistance ...

Introduction.?The senior writer, Burke (1943), made an appeal for an efficient successor to neostibosan (Bayer), this, preferably, to be a British product. What seems to be an almost perfect answer to that appeal?and indeed a British product?is the preparation stibatin (Glaxo Laboratories), or sodium antimony gluconate (antimony v-hexonate), a crystal-clear sterile solution containing 20 mg. of...

This work report on the structural and electrical characteristics of zinc oxide single crystal samples doped with antimony. Doping was carried out by antimony thermal diffusion at 1000 °C for periods of one and two hours under nitrogen environment from a solid source formed by antimony oxide. X-ray diffraction was used to determine the crystalline phases in samples and the structural change owi...

A model is presented that describes the pumping characteristics of St707 getter material, the evaporation rate of antimony, and the resulting partial pressure of Sb within a vacuum chamber. The results show that within the 250-450◦C range, the partial pressure of antimony ranges from 10−7 Pa to 10−2 Pa. In a limiting case where the getter efficiency is tuned to 10, 000 L/s, partial pressures ar...

the trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. a very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. these elements may be concentrated in non-magnetic and magnetic part of calcrete. based on the current research, mineralogica...

a highly selective, sensitive, rapid and economical differential pulse polarographic method has been developed for the determination of trace amounts of antimony in various standard alloys and biological samples after adsorption of its 2-nitroso-1-naphthol-4-sulfonic acid - tetradecyldimethylbenzylammonium chloride on microcrystalline naphthalene in the ph range of 7.5-11.0. after filtration, t...

introduction: the lymphatic system provides one of the main paths for the spread (metastasis) of cancer from one part of body to another. hodgkin’s diseases, lymphocytic leukemia, various metastatic disease and many lymph node disorders can be assessed by lymphoscintigraphy. radionuclide lymphoscintigraphy has been used for many years to define lymphatic drainage of melanoma. the most common ra...

then again there is the Bravo case, and those of Cook, llcMullan and Winslow, and lastly, the more'recent cases of Palmer and Klosowski. Poisoning by salts of antimony has occasionally been recorded in India, but it is usually spoken of as a rare occurrence in this country Is this really the fact, and lias arsenic such an absolute monopoly for criminal purposes as is generally believed ? Althou...

It is suggested that the story of The Magic Flute owes much to alchemy and related early mineralogy; the operaÕs architectonic structure, including its musical structure, owes much to numerology. The plot is in large part an allegorical account or description of the alchemical process and the production of the PhilosophersÕ Stone from the prima materia stibnite (spiessglanz) (antimony trisulphi...
