water and soil pollution by human pathogenic bacteria draw attention of many researchers. duration of bacterial survival for reach to the soil and water resources is very important. current study focused on the effects of caco3 and caso4 compounds on escherichia coli survival. using caco3, caso4 compounds and fine sand particles (

The vast majority of carbonate minerals in modern marine sediments are biogenic, derived from the skeletal remains organisms living ocean. However, can also precipitate abiotically within sediments, and this mineral precipitation has been suggested as a third major, isotopically distinct, sink global carbon cycle, particularly important earlier Earth history. Here we present compilation pore fl...

We present pore fluid geochemistry, including major ion and trace metal concentrations the isotopic composition of calcium sulfate, from uppermost meter sediments Gulf Aqaba (Northeast Red Sea) Iberian Margin (North Atlantic Ocean). In both locations, we observe strong correlations among calcium, magnesium, strontium, sulfate as well sulfur alkalinity, suggestive active changes in redox state p...

Excessive calcium influx is important in the irreversible injury of cardiac myocytes and other cell types. The mechanism is unknown, but possibilities include L-type channels, Na(+)-Ca2+ exchange, sarcolemmal (SL) defects, and calcium leak channels. In this study, metabolic inhibition was used to induce ATP depletion and augmented calcium influx in cultured cardiac myocytes. Inhibition of the L...

magnesium sulfate is widely used in obstetrics and is drug of choice in two important complications of pregnancy, preeclampsia and preterm labor. the antagonistic effects of magnesium sulfate on calcium ion and on platelet aggregation may lead to changes in bleeding time. this study was conducted to evaluate the effect of magnesium sulfate on bleeding time in women with threatened preterm labor...

Elevated sulfate concentrations in industrial effluent can lead to a number of significant problems, the most serious of which is the corrosion of concrete sewers as a result of hydrogen sulfide induced biogenic sulfuric acid attack; hydrogen sulfide can also create odor nuisance problems. The most common treatment process for sulfate removal from wastewaters is to precipitate it as gypsum usin...

Anion transporters NaS1 (SLC13A1) and Sat1 (SLC26A1) mediate sulfate (re)absorption across renal proximal tubule and small intestinal epithelia, thereby regulating blood sulfate levels. Disruption of murine NaS1 and Sat1 genes leads to hyposulfatemia and hypersulfaturia. Sat1-null mice also exhibit hyperoxalemia, hyperoxaluria, and calcium oxalate urolithiasis. This review will highlight the cu...

Abstract In this study, the influence of calcium formate (CF) on hydration a synthesized sulfate hemihydrate (HH) powder was investigated. Isothermal calorimetry measurements showed that CF retards reaction HH. This confirmed by XRD stored samples and pore solution analysis. Two retardation mechanisms were identified. The combination laser granulometric experiments revealed firstly, initial dis...

BACKGROUND Iron, zinc, and calcium can interact with each other in a way that inhibits their respective absorption. On the other hand, mineral fortification has been used to improve simultaneous iron and zinc absorption from food supplements. OBJECTIVE We evaluated the effect of a novel fortificant mixture consisting of NaFeEDTA, zinc methionine, ascorbic acid, and citric acid on iron and zin...
