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...

this study was carried out in order to evaluate the changes of nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of leonardite and foliar application of n and k. the experiment was conducted in gorgan university of agricultural sciences and natural resources during 2013- 2014. the experiment was laid out a using split-plot arrangement based ...

Potassium chloride is a leading reformulation technology for reducing sodium in food products. As, globally, sodium intake exceeds guidelines, this technology is beneficial; however, its potential impact on potassium intake is unknown. Therefore, a modeling study was conducted using Dutch National Food Survey data to examine the dietary impact of reformulation (n = 2106). Product-specific sodiu...

Cadmium uptake by nonliving and resting cells of Saccharomyces cerevisiae obtained from aerobic or anaerobic cultures from pure cadmium-bearing solutions was examined. The highest cadmium uptake exceeding 70 mg Cd/g was observed with aerobic baker's yeast biomass from the exponential growth phase. Nearly linear sorption isotherms featured by higher sorbing resting cells together with metal depo...

Four granulates were prepared from waste, including lignite ash, industrial sludge, sawdust, ammonium nitrate and potassium salt (60% K2O). The produced chemically tested. They contained significant Ca C organic contents slightly less S, P, K Mg. concentration of Cd, Cr, Cu, Ni, Pb Zn did not exceed the applicable standards. Then, they tested in a experiment with 2 plants: spring rape, Larissa ...

The main aim of the study was to evaluate the various minerall and heavy metals parameters of seaweeds present in the south coastal line. The five red seaweeds namely Acanthophora deliei, Scinaia furcellata, Porphyra tenera, Gracilaria verucosa and Hypnea species were collected from the Pamban, South east coast India. These samples were analyzed for its mineral contents such as sodium, potassiu...

The uptake of cadmium in vivo into parenchymal and non-parenchymal (sinusoidal) cells of the liver was studied by a cell-separation technique. Liver parenchymal cells accumulate cadmium more readily than do non-parenchymal cells and synthesize metallothionein. It is proposed that cadmium uptake and metabolism from injected CdCl2, is restricted almost exclusively to the liver parenchymal cells.

The health effects of low-level chronic exposure to cadmium are increasingly recognized. To improve the risk assessment, it is essential to know the relation between cadmium intake, body burden, and biomarker levels of cadmium. We combined a physiologically-based toxicokinetic (PBTK) model for cadmium with a data set from healthy kidney donors to re-estimate the model parameters and to test the...

     For investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the Research Field of Islamic Azad University, Jiroft, Iran in 2013-2014. The main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of ...

To determine the effects of potassium supplementation on endothelial function, cardiovascular risk factors, and bone turnover and to compare potassium chloride with potassium bicarbonate, we carried out a 12-week randomized, double-blind, placebo-controlled crossover trial in 42 individuals with untreated mildly raised blood pressure. Urinary potassium was 77+/-16, 122+/-25, and 125+/-27 mmol/2...
