To evaluate innate effects of certain trace elements, 540 mice were fed a diet of rye, corn oil and dried skim milk containing moderate amounts of zirconium and niobium and no detectable antimony or fluorine, in an environment relatively free of trace contaminants. Groups of 108, divided as to sex, were given 5 ppm zirconium, niobate or antimony or 10 ppm fluoride in drinking water from weaning...

BACKGROUND Leishmaniasis is a common parasitic disease in Southern Europe, caused by Leishmania infantum. The failures of current treatment with pentavalent antimonials are partially attributable to the emergence of antimony-resistant Leishmania strains. This study analyses the in vitro susceptibility to pentavalent antimony of intracellular amastigotes from a range of L. infantum strains, deri...

Arsenic and antimony are toxic metalloids, naturally present in the environment and all organisms have developed pathways for their detoxification. The most effective metalloid tolerance systems in eukaryotes include downregulation of metalloid uptake, efflux out of the cell, and complexation with phytochelatin or glutathione followed by sequestration into the vacuole. Understanding of arsenic ...

Kumbakonam Hospital with the characteristic disease. Duration?six months. 23rd October, 1916, 2 ounces of a solution of antimony tartarate (1 erain in 2 oz. of distilled water) was given intravenously. Two days afterwards the surface showed signs of healing. On 30th October, 1916, my house surgeon gave another injection of the same strength. The patient is said to have left the hospital on 25tl...

Nine new Sb-bicapped α-Keggin-type heteropolyoxoniobates (HPNb) were synthesized under hydrothermal conditions. Among them, the As-centered HPNb was never reported before, and the two dimer compounds are the biggest isolated HPNbs at present.

Antimony oxide (Sb2O3) and Antimony-doped iron (Sb-Fe2O3) nanomaterials of different (2 &3 %) concentrations were fabricated by wet synthesis technique characterized FTIR, XRD XRF techniques, respectively. X-RD results showed uniform Iron nanocrystals almost 15 nm, whereas FTIR employed to detect elemental composition in doped samples.
