Antimonial-containing drugs are the first line of treatment against Leishmaniasis. Resistance to antimonials in Leishmania is proposed to be due to reduced uptake of trivalent antimony (SbIII) through the aquaglyceroporin (AQP1). We investigated the uptake of SbIII and involvement of aquaglyceroporin in developing antimony resistance phenotype in Leishmania donovani clinical isolates. SbIII acc...
Antimony (Sb) is a toxic metalloid that occurs widely at trace concentrations in soil, aquatic systems, and the atmosphere. Nowadays, with the development of its new industrial applications and the corresponding expansion of antimony mining activities, the phenomenon of antimony pollution has become an increasingly serious concern. In recent years, research interest in Sb has been growing and r...
beginning of a spectacular career for antimony in chemistry and medicine" (p. 14). The internal use of antimony and its compounds was most widespread during the seventeenth century: despite periodic warnings about its poisonous nature, its apparent ability to expel undesirable humours from the body by promoting sweating, vomiting and purging-ensured its acceptance in medical practice, particula...
Poly(3-hexylthiophene) (P3HT), as a traditional organic hole-transporting material (HTM), is widely used in thin-film solar cells due to its high charge mobility and good thermal stability. However, the P3HT films obtained by method are amorphous, which unfavorable hole extraction transport. Here, low-toxicity solvent 1,2,4-trimethylbenzene (TMB) was instead of commonly halogen chlorobenzene (C...
We aimed to study the characteristics and the mechanism of the cumulative release of antimony at an antimony smelting slag stacking area in southern China. A series of dynamic and static leaching experiments to simulate the effects of rainfall were carried out. The results showed that the release of antimony from smelting slag increased with a decrease in the solid-liquid ratio, and the maximum...
It is very important to investigate antimony geochemical behavior in order to identify its source, or reveal contamination processes, since antimony and its compounds are considered to be pollutants of high priority by the Environmental Protection Agency of the United States (USEPA). However, the concentration of antimony in most geological samples is very low, and its stable isotope mass diffe...
LLE Review, Volume 142 110 Introduction Zinc sulfide (ZnS) is an infrared (IR) optical material widely used for applications such as IR windows, domes, and optical lenses.1 It is industrially produced by the chemical-vapor–deposition (CVD) technique to reach a dense, milky yellow–orange color, with +70% transmission in the mid-long-wave IR region.1 Its inner structure consists of cone-like stru...
BACKGROUND Although high dose of antimony is the mainstay for treatment of American cutaneous leishmaniasis (ACL), ongoing major concerns remain over its toxicity. Whether or not low dose antimony regimens provide non-inferior effectiveness and lower toxicity has long been a question of dispute. METHODS A single-blind, non-inferiority, randomized controlled trial was conducted comparing high ...
