Cadmium Toxicity and Treatment

TL;DR: This study synthesizes mesoporous materials functionalized with phosphinic acid ligand and evaluates their cadmium removal efficiency from nitrate medium, with calcined and impregnated mesoporous silica showing the best performance and maximum sorption capacity of 22.16 mg/g.

TL;DR: This study investigates cadmium resistance and adaptive response in Saccharomyces cerevisiae quiescent cells, finding similar IC50 values for diploid and haploid strains, but varying ROS and protein carbonylation levels, and increased antioxidant defense system expression in response to elevated cadmium concentrations.

TL;DR: This study optimizes cadmium ions biosorption onto Trichoderma fungi using a central composite design, achieving a 98.8% removal efficiency under optimal conditions of pH 6, 120-minute contact time, and 25 mg/L initial cadmium concentration.

Abstract: Cadmium is a non-essential metal which because of its extensive use in industry and agriculture presents a worldwide health hazard. Long-term exposure to cadmium results in nephropathy characterised by interstitial nephritis affecting the renal tubules. In addition to occupational exposure, cadmium can contaminate food and water increasing the number of people at risk of developing chronic renal disease. It is now known that smoking is an independent risk factor for renal disease. The current knowledge of the molecular mechanisms initiating and progressing cadmium nephrotoxicity is now partly understood and research on the molecular effects of nicotine on the kidney is ongoing. The exacerbation of renal disease by smoking is an increasing problem. It is concluded that where there is potential exposure to cadmium, either occupationally or environmentally, individuals should be encouraged to cease smoking.

TL;DR: In this paper, a new calculation of the crustal composition is based on the proportions of upper crust (UC) to felsic lower crust (FLC) to mafic lower-crust (MLC) of about 1.6:0.4.

TL;DR: This review summarizes recent findings in the metal-induced formation of free radicals and the role of oxidative stress in the carcinogenicity and toxicity of metals.

TL;DR: D diagnosis of mercury toxicity can be challenging but can be obtained with reasonable reliability and effective therapies for clinical toxicity have been described.

TL;DR: The current review gives an overview on Cd-induced ROS production and anti-oxidative defense in organisms under different Cd regimes and the C d-induced oxidative challenge is discussed with a focus on damage and signaling as downstream responses.
