The toxicity of cadmium for the Collembola Folsomia candida was studied by determining the effects of increasing Cd concentrations on growth, survival and reproduction in three cultivated and forested soils with different pH (4.5-8.2) and organic matter content (1.6-16.5%). The Cd concentration in soil CaCl(2) exchangeable fraction, in soil solution and in Collembola body was determined. At sim...

Significant quantities of Cd have been added to soils globally due to various anthropogenic activities, posing a serious threat to safe food production and human health. Rhizosphere, as an important interface of soil and plant, plays a significant role in the agro-environmental system. This article presents a review of relationship between root excretion and microorganisms and plant resistance ...

The effect of cadmium (Cd) on growth, photosynthesis, biochemical attributes and antioxidant enzymes activities in tomato (Solanum lycopersicum L.) seedlings was studied and the role of kinetin (KN) to ameliorate Cd toxicity was examined. Tomato seedlings were subjected to two doses of Cd viz. 3 and 9 mg Cd kgP P sand. Cadmium at both the doses significantly declined the growth and photosynthes...

Cadmium (Cd) is a well-known human carcinogen and a potent nephrotoxin. Curcumin, the yellow bioactive component of turmeric has established its antioxidant activities. The aim of this study was to investigate the protective role of curcumin against Cd induced nephrotoxicity. The rats were treated once daily by oral gavage for five days and divided into four groups of 8 rats each: control, Cd a...

BACKGROUND Carbon nanodots (CD), a new class of carbon nanomaterials with sizes below 10 nm, have recently attracted wide attention due to their superiority in water solubility, chemical inertness, and resistance to photobleaching. As a result, CD has found important and wide applications in energy, catalysis, biological labeling, bioimaging and drug delivery. On the other hand, due to the lack...

Chronic exposure to cadmium (Cd) is known to adversely affect renal function. Our previous studies indicated that Cd induces p53-dependent apoptosis by inhibiting gene expression of the ubiquitin-conjugating enzyme (Ube) 2d family in both human and rat proximal tubular cells. In this study, the effects of Cd on protein expression of p53 and apoptotic signals in the kidney and liver of mice expo...

Metallothionein is a naturally occurring metal-binding protein with high cysteine content. Oligopeptides containing three cysteinyl residues and having amino acid sequences analogous to portions of this protein were synthesized by the solid-phase method. Strong affinity of the synthetic peptides to Cd2+ and Zn2+ was observed, and the dissociation constants of the peptide-metal complexes were 2-...

cadmium (cd), known as a non-essential heavy metal, can cause oxidative stress in plants. in this study, an attempt was carried out to find out whether cd-induced oxidative and microscopic changes could be observed in the early stage of seedling growth. seeds of brassica napus (cvs. zheda 619 and zs 758) were germinated in vitro at 0, 100, 200, 300, and 500 μm cd concentrations in dark for 48 h...

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 ...
