Objective Metals can cause male infertility through affection of spermatogenesis and sperm quality. Strong evidences confirm that male infertility in metal-exposed humans is mediated via various mechanisms such as production of reactive oxygen species (ROS). Flavonoids have antioxidant and metal chelating properties which make them suitable candidates for neutralizing adverse effects of metals ...

Cadmium is a major environmental toxicant that is released into the atmosphere, water and soil in the form of cadmium oxide, cadmium chloride, or cadmium sulfide via industrial activities, such as the manufacturing of batteries and pigments, metal smelting and refining and municipal waste incineration. In the present study, we investigated the effects of cadmium exposure on sperm quality parame...

This study pertains to the role of selenium against the toxic manifestations of chronic cadmium exposure. The kidney is a recognized target organ for chronic cadmium exposure, owing to the very long half-life of cadmium. Cadmium (as cadmium chloride) in a dose of 8 mg kg-1 body wt. was administered orally for a period of 8 weeks in mice. This resulted in a significant decrease in total reduced ...

the aim of this study was to examine the effect of swimming submaximal training and cadmium consumption on cardiac hif1-α and vascular endothelial growth factor (vegf) in pregnant rats. 32 pregnant wistar rats were randomly divided into 4 groups: cadmium, swimming, cadmium+swimming and control. experimental groups performed the swimming protocol for 3 weeks, 5 sessions a week for 60 minutes per...

Stimulation with heavy metals is known to induce calcium (Ca(2+)) mobilization in many cell types. Interference with the measurement of intracellular Ca(2+) concentration by the heavy metals in cells loaded with Ca(2+) indicator fura-2 is an ongoing problem. In this study, we analyzed the effect of heavy metals on the fura-2 fluorescence ratio in human SH-SY5Y neuroblastoma cells by using TPEN,...

In order to better comprehend onset and progression of diseases such as cancer, the means by which genes are regulated must be understood. RNA Polymerase II (Pol II) transcribes mRNAs that are translated into proteins, but this process is tightly controlled by transcription factors that recruit Pol II to promoter elements. These transcription factors determine if and when a gene is expressed at...

Treatment of mouse hepatoma (Hepa) cells with heme or cadmium chloride in serum-free medium causes a rapid increase in the steady-state level of heme oxygenase (HO) messenger RNA. This increase is both dose- and time-dependent. Maximum accumulation of HO mRNA is observed 3 h after addition of either agent. Treatment of Hepa cells with heme or CdCl2 also stimulates the transcription of the HO ge...

background: cadmium (cd) intoxication can cause oxidative stress and involve the antioxi-dant defense system in hepatocytes. administration of vitamin c, chitosan, or a combination of both may prevent cd-induced oxidative damage. methods:cyprinus carpio were distributed into six groups. the control group received normal feed (group i). group ii was exposed to 0.2 mg.l-1 cadmium chloride. group ...

Cadmium metabolism in the young and in conditions of dietary contamination with ash from coal gasification were investigated. The experiments were performed in adult rats which received ash in the diet (5%) and/or cadmium in drinking water (100 ppm) over a period of five weeks and in sucklings whose mothers were given the same treatment throughout pregnancy and lactation. In pharmacokinetic stu...
