cadmium (cd), being a highly toxic metal pollutant of soils, it inhibits root and shoot growth and yield production, affects nutrient uptake and homeostasis. it is frequently accumulated by agriculturally important crops and then enters the food chain with a significant potential to impair animals and human’s health. therefore, a study was conducted to evaluate the effects of various cd levels ...

Aquatic insects often dominate lotic ecosystems, yet these organisms are under-represented in trace metal toxicity databases. Furthermore, toxicity data for aquatic insects do not appear to reflect their actual sensitivities to metals in nature, because the concentrations required to elicit toxicity in the laboratory are considerably higher than those found to impact insect communities in the f...

Cadmium (Cd) contamination, which poses a serious threat to human health, has been recognized as major the agricultural system and crop production. Salicylic acid (SA) is signaling molecule that plays an important role in against Cd toxicity. Previously, we found spraying rice with SA could reduce accumulation grains grown Cd-contaminated soil. In this study, studied specific mechanism of spray...

The aim of this paper was to evaluate the potential sediment cumulative damage and toxicity due to metal contamination in a polluted zone of Deûle river (in northern France) from nearby two smelters. Metal-enrichment factors and geoaccumulation indices measured with sediment depth revealed that--compared to background levels either in local reference soils or in world rivers sediments/suspended...

Tomato is an important crop from nutritional and economical points of view, and it is grown in greenhouses, where special substrates and the use of recycled water imply an increased risk of Cd accumulation. We investigated tomato root responses to low (10 microM) and high (100 microM) Cd concentrations at the root proteome level. Root extract proteome maps were obtained by 2-DE, and an average ...

To clarify toxic effects of long-term oral administration of low dose cadmium (Cd) on the liver and kidney, six groups of female Sprague-Dawley rats were fed a diet containing Cd-polluted rice or CdCl2 at concentrations up to 40 ppm, and killed after 12, 18, and 22 months. With toxicological parameters, including histopathology, there was no evidence of Cd-related hepato-renal toxicity, despite...

Cadmium (Cd) is one of the most toxic non-essential and mobile metallic elements found in soils which affects plant growth. A greenhouse experiment was carried out to determine the genotypic differences in effects of different levels of Cd application on yield and on the uptake of Cd and other nutrients in various Brassica plant parts. The B. juncea (Indian mustard) genotypes produced higher bi...

Niemann-Pick type C (NPC) disease is an autosomal recessive lysosomal trafficking disorder, in which the cholesterols are abnormally accumulated in lysosomes. Recently, the β-cyclodextrin (CD) derivatives are revealed to show therapeutic effect for NPC disease through the removal of accumulated cholesterols in lysosomes. Herein, to enhance the therapeutic effect and reduce the toxicity of β-CD ...
