The effects of cadmium administered via ambient water or food on plasma ions of the Af rican freshwater cichlid Oreochromis mossambicus were studied for 2, 4, 14, and 35 days, in low cal cium (0.2 mM) and high calcium (0.8 mM) water. In low calcium water, an environmentally relevant concentration of 10 fig/L water-borne cadmium in duced a significant and dramatic hypocalcemia on days 2 and 4...
Background and Aims: Cadmium (Cd) is a nephrotoxic environmental pollutant, and microRNAs have been recently investigated as potential biomarkers for the diagnosis and pathology study of certain diseases. The present study aimed to determine the protective effect of aerobic physical activity on the changes of mir-21 and mir-146-b in renal tissue caused by cadmium chloride in male rats. Materia...
BACKGROUND Cadmium (Cd) is a potent nephrotoxicant that impairs the reabsorptive and secretory functions of the renal proximal tubule, leading to albuminuria. OBJECTIVES To gain insights into the mechanisms of Cd-induced albuminuria, we investigated effects of Cd on the expression of megalin and chloride channel 5 (ClC5), two key players in albumin-receptor-mediated endocytosis. METHODS We ...
The environmental changes by human activities lead to contamination of natural ecosystems and agricultural lands to heavy metals such as cadmium (Cd), which enumerates the most important environmental pollutants. This experiment was conducted for study of cadmium and mycorrhizal symbiosis effects on growth and physiological parameters as well as cadmium accumulation in Black seed (Nigella sativ...
Cadmium is a toxic element in plant nutrition and is considered as a contaminant of food and feed. A greenhouse experiment was carried out to examine the effects of combined application of cadmium and zinc on responses of wheat on a clay loam soil texture. This experiment was designed in a factorial experiment with randomized complete block design (RCBD) and four replicates per treatment. Three...
Sir, A 32-year-old African-American male construction worker and martial arts student presented to the emergency room complaining of generalized weakness that was more pronounced in the lower extremities and confined him to bed. Weakness began about 12 h after vigorous physical exercise and ingestion of a high carbohydrate diet. He had no significant personal or family medical history. Initial ...
Pollution of the aquatic environment by heavy metals has become a worldwide problem. Most heavy metals exhibit toxic waste on aquatic organisms. Cadmium (Cd) is a highly toxic metal which affects aquatic organisms acutely and chronically. Planktonic calanoid copepods are the secondary dominant producers of pelagic ecosystems and play a considerable role in the transfer of energy and organic mat...
the impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence ofcadmium (100 μm) were investigated. inhibitory effects of cadmium on seedling growth resulted in reduced shoot and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars contents and a low rate of lipid peroxidation. results indic...
irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. this experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (k) with that of di...
