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...

It has been shown previously that antimony evaporated onto a Au(111) surface grows in a layer-bylayer mode. The present work compares the initial, fast-oxidation stage of these films with that on bulk polycrystalline antimony. Measurements were carried out in an ultrahigh-vacuum environment using Auger electron spectroscopy, low-energy electron diffraction, electron-energy-loss spectroscopy, an...

BACKGROUND The aim of this study was to observe the concentrations of trace metals boron, lithium, rubidium, antimony, tin and strontium in the serum of athletes from different modalities and sedentary subjects and the possible influence that different energy sports training modalities can have on their concentration. METHODS Eighty professional athletes and 31 sedentary males participated in...

Pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate, have been used for more than half a century in the therapy of the parasitic disease leishmaniasis. Even though antimonials are still the first-line drugs, they exhibit several limitations, including severe side effects, the need for daily parenteral administration and drug resistance. The molecular structure of ...

Visceral leishmaniasis (VL) caused by the protozoan parasite Leishmania infantum, is one of the most important zoonotic diseases affecting dogs and humans in the Mediterranean area. The presence of infected dogs as the main reservoir host of L. infantum is regarded as the most significant risk for potential human infection. We have studied the susceptibility profile to antimony and other anti-l...

BACKGROUND Drug resistance is a major problem in leishmaniasis chemotherapy. RNA expression profiling using DNA microarrays is a suitable approach to study simultaneous events leading to a drug-resistance phenotype. Genomic analysis has been performed primarily with Old World Leishmania species and here we investigate molecular alterations in antimony resistance in the New World species L. amaz...
