Heavy metal orchestration [PDF]

open access: possibleNature Chemistry, 2020
Many current methods to prepare 2-hydroxybiaryls require the prefunctionalization of phenol groups or show limited substrate scope. Now, use of a pentavalent sulfone-bridged bismacycle, formed in situ by telescoped boron-to-bismuth transmetallation and oxidation, allows the direct and regioselective ortho-arylation of unprotected phenols.

Heavy Metal

Journal of Craniofacial Surgery, 1996
A 19-year-old Crouzon's syndrome patient with a history of multiple craniofacial procedures presented with severe bilateral temporal and frontal depressions and metal implants protruding through the scalp in multiple locations. Preoperative analysis revealed an extensive cranial defect that had been reconstructed with multiple large metallic mesh ...

Biosensors for heavy metals

BioMetals, 2005
A biosensor is an analytical device that consists of an immobilized biocomponent in conjunction with a transducer, and represents a synergistic combination of biotechnology and microelectronics. This review summarizes the use of biosensors for detecting and quantifying heavy metal ions.

HEAVY METALS AND FERTILITY

Journal of Toxicology and Environmental Health, Part A, 1998
Heavy metals have been identified as factors affecting human fertility. This study was designed to investigate whether the urinary heavy metal excretion is associated with different factors of infertility. The urinary heavy metal excretion was determined in 501 infertile women after oral administration of the chelating agent 2,3-dimercaptopropane-1 ...
