Two red macroalgae species, Gracilaria cornea and Chondrophycus poiteaui, were evaluated for their intra and extracellular Cd2+ accumulation capacity, photosynthetic response and thiol peptide production. Algae were exposed for 3 and 7 days to 0.1 and 1 microg CdCl2 ml(-1) (0.89 and 8.9 microM). Intracellular accumulation of Cd2+ by G. cornea was relatively low, only comprising 20% of total met...

The present study aimed to elucidate the structural changes in testis and epididymis of adult rats following subchronic peroral administration of cadmium at 30 mg/L, diazinon at 40 mg/L, cadmium at 30 mg/L, and diazinon at 40 mg/L, respectively. At the end of 90-day experiment, the samples of the testes and epididymis were assayed by qualitative and quantitative histological methods. The testis...

Phytoremediation is one of the most widely used methods for removing soil contaminants. In this research, the function of Vetiveria zizianoides to remove cadmium from four different treatments with varying amounts of cadmium chloride contamination (including 0, 20, 40, and 60 mg per liter) was investigated and physiological changes caused by the accumulation of this metal in the plant were moni...

Five new thiosulfate based inorganic-organic hybrid open-framework compounds have been synthesized employing mild reaction conditions. Of the five compounds, [Na(2)(H(2)O)(8)][Cd(C(10)H(8)N(2))(S(2)O(3))(2)].2H(2)O, I and [Cd(2)(C(10)H(8)N(2))(2)(HS(2)O(3))(2)(S(2)O(3))(2)][(C(10)H(9)N(2))(2)(C(10)H(8)N(2))(2)].8H(2)O, II have one-dimensional (1D) structures and [Cd(C(10)H(8)N(2))(H(2)O)(2)(S(2...

Langmuir–Blodgett (LB) technique has been used to deposit composite multilayers of poly(3-octylthiophene) with cadmium arachidate (POT-CdA), zinc arachidate (POT-ZnA) and copper arachidate (POT-CuA). These composite multilayers were used as precursors to develop the respective semiconducting CdS, ZnS and Cu2S nanoclusters in the POT-arachidic acid (POT-AA) matrix. The formation of sulphide nano...

Abstract: In this work we investigate the electronic, optical, dynamic and thermoelectric properties of ternary copper-based Chalcogenides CuSbX2 (X= S, Se) compounds. Calculations are based on density functional theory and the semi-classical Boltzmann theory. Computations have been carried out by using Quantum-Espresso (PWSCF) package and ab-initio pseudo-potential technique. To estimate the e...

In recent years perovskite based solar cells have become a promising photovoltaic technology, most notable for their high power conversion efficiencies and potential for cheap solution-processable module production. This report identifies the ongoing research and development into the behaviour of the perovskite material as a semiconducting active area and the ever improving fabrication of perov...

The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams' E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 microM). Hepatocytes incubated in the MWE medium without cadmiu...

The combined carcinogenic effect of cadmium and dimethylnitrosamine (DMN) was examined in male Wistar rats, to test whether the previously observed synergism in mutagenicity between cadmium and 2 N-nitroso compounds would be paralleled by a synergism in carcinogenicity. In experiment 1, 50 five-month old rats received 18 mg DMN/kg i.p. followed by cadmium i.m. in two injections totaling either ...
