The participation of renal metallothionein (Ml) in the toxicity and antitumor activity of cii-diamminedichloroplatinum(II) (cw-DDP) in male mice was examined. Preinduction of MT in the kidney by the s.c. administration of bismuth compounds decreased the lethality and renal and gastrointestinal toxicity caused by a single s.c. injection of c/j-DDP. In the present study a correlation between the ...
Bi Lewis acidic: Donor-free cationic bismuth compounds readily coordinate basic substrates including arenes, phosphanes, and isonitriles, degrade the weakly coordinating counter-anion [PF6]–. Counterintuitively, an increase in steric bulk around can acidity. In graphic, a kraken grabs substrates, solving scientific puzzles about bismuth-based More information be found Research Article by C. von...
The biochemical transformation of mercury, tin, arsenic and bismuth through formation of volatile alkylated species performs a fundamental role in determining the environmental processing of these elements. While the toxicity of inorganic forms of most of these compounds are well documented (e.g., arsenic, mercury) and some of them are of relatively low toxicity (e.g., tin, bismuth), the more l...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
Introduction: In recent years, bismuth-based nanomaterials have been widely used in medical researches as imaging, drug delivery and x-ray radiosensitizing agents. Due to their anti-microbial effects against Helicobacter pylori (HP), bismuth colloidal compounds are used to treat various types of diseases such as chronic gastritis. Despite their advantages, bismuth-based compoun...
