Antimony toxicity occurs either due to occupational exposure or during therapy. Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition antimony trioxide is possibly carcinogenic to humans. Improvements in working conditions have...

Aquaporins (AQPs), members of a superfamily of transmembrane channel proteins, are ubiquitous in all domains of life. They fall into a number of branches that can be functionally categorized into two major sub-groups: i) orthodox aquaporins, which are water-specific channels...

The presence of methylated antimony species has been reported in surface waters, sediments, soils, and biota, mainly detected using hydride generation techniques. Compared to other elements, relatively few studies have been published. Monomethyl-, dimethyl-, and trimethylantimony species have been found...

Together with vector control, chemotherapy is an essential tool for the control of visceral leishmaniasis (VL), but its efficacy is jeopardized by growing resistance and treatment failure against first-line drugs. To delay the emergence of resistance, the use of drug...

Antimony (Sb) is ubiquitous throughout the environment as a result of natural processes and human activities. In China, superlarge-, large and medium-sized Sb deposits are concentrated in the Guangxi (34.4%), Hunan (21.2%), Yunnan (12.2%) and Guizhou (10.2%) provinces. Due to...

Pentavalent antimonials have been the mainstay of antileishmanial therapy for decades, but increasing failure rates under antimonial treatment have challenged further use of these drugs in the Indian subcontinent. Experimental evidence has suggested that parasites which are resistant against antimonials...

We show that increased plasma superoxide dismutase 1 (SOD1) levels are statistically significant predictors of the failure of pentavalent antimony treatment for cutaneous leishmaniasis caused by Leishmania braziliensis. In Leishmania amazonensis-infected patients, host SOD1 levels can be used to discriminate...
