Three potent tumor promoters of different classes, 12-O-tetradecanoylphorbol-13-acetate, dihydroteleocidin B, and aplysiatoxin, and two moderate tumor promoters, mezerein and debromoaplysiatoxin, enhanced the frequency of appearance of cadmium-resistant Chinese hamster lung cells when the cells were exposed to cytotoxic levels of CdCl2. With these compounds, the activity to induce cadmium-resis...

OBJECTIVES To study longitudinal biological monitoring data on urinary and blood cadmium collected in a small cohort of nine workers who had been brazing for several years with solders containing cadmium. METHODS Cadmium was measured by neutron activation analysis in livers and kidneys, and estimates of renal function were carried out in 1983 and 1995. During the intervening period exposure t...

Cadmium, inorganic arsenic and, potentially, dimethyl acid are carcinogens widely elevated in rice. Here it was identified that the food-safe and common cadmium chelator citric efficiently removed from intact grain via pre-soaking procedure, while also reducing species. A twostep stage developed whereby rice first incubated, at ambient temperature, 1 M for 12 h, then calcium carbonate another l...

The phosphotriesterase from Pseudomonas diminuta catalyzes the hydrolysis of organophosphate esters. The isolated native protein contains zinc, and removal of this metal abolishes the enzymatic activity. Reconstitution of the apoenzyme requires 2 mol of cadmium per mol of protein for full catalytic activity. The kcat and Km values for the hydrolysis of paraoxon for the cadmium-substituted enzym...

The present study investigates the biosorption of cadmium ions from aqueous solution onto unmodified, ultrasound and microwave treated cells of Saccharomyces cerevisiae. FTIR analysis was conducted to characterize the biosorbent. Equilibrium and kinetic studies of unmodified RBW (residual brewery waste) cell yeast and DSM 1333 (pure strain) were conducted by considering the effect of initial ca...

Environmental pollutants have hazardous impact on living organism present on this planet. Environmental pollutants give bad impact on the health of livestock as well as human beings and have been categorized as heavy metals, pesticides etc. Cadmium and its compounds are most common environmental toxicants with potential for bioaccumulation and persistence in the body, and produce versatile biot...
