In certain regions of the predominantly nitrogen limited ocean, microbes can become co-limited by phosphorus. Within such regions, a proportion of the dissolved organic phosphorus pool can be accessed by microbes employing a variety of alkaline phosphatase (APase) enzymes. In contrast to the PhoA family of APases that utilize zinc as a cofactor, the recent discovery of iron as a cofactor in the...

Phosphorus removal in waste stabilization ponds (WSP) is highly variable, but the reasons for this are not well understood. Luxury uptake of phosphorus by microalgae has been studied in natural systems such as lakes but not under the conditions found in WSP. This work reports on the effects of phosphate concentration, light intensity, and temperature on luxury uptake of phosphorus by WSP microa...

carbonatic origin of most arable land in the country, caused to decrease phosphatic fertilizer use efficiency and because of this phenomenon, farmers annually add a large amount of these chemical compounds to their field to get proper results. international shortage and increasing prices create some problems for importing phosphorus fertilizers to the country. on the other hand using more and m...

To investigate the correlations among seminal plasma Magnesium (Mg), Phosphorus (P), Potassium (K), Calcium (Ca), Chromium (Cr), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Selenium (Se), Molybdenum (Mo) and Iodine (I) concentrations and semen parameters [1– 15]. 500 fertile and 1000 infertile males provided a standardized semen specimen. Total Magnesium (Mg), Phosphorus (P), Potassium (...

Many late-onset proteotoxic diseases are accompanied by a disruption in homeostasis of metals (metallostasis) including iron, copper and zinc. Although aging is the most prominent risk factor for these disorders, the impact of aging on metallostasis and its role in proteotoxic disease remain poorly understood. Moreover, it is not clear whether a loss of metallostasis influences normal aging. We...

The different combinations of phosphorus to be found in a given tissue may be divided into three main groups: I. Protein phosphorus or phosphorus in combination with protein, including nucleoprotein and phospho-proteins or nucleoalbumins, insoluble in water especially after treatment with alcohol; 2. Lecithin and kephalin phosphorus or phosphorus in combination with fat and a nitrogen complex, ...

New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...

The water-soluble zinc salts gluconate, sulfate, and acetate are commonly used as supplements in tablet or syrup form to prevent zinc deficiency and to treat diarrhea in children in combination with oral rehydration. Zinc citrate is an alternative compound with high zinc content, slightly soluble in water, which has better sensory properties in syrups but no absorption data in humans. We used t...

In the preformulation study physical compatibility of the drug-excipient was screened and compatibility was observed between Zaltoprofen and selected solubilizers. In the drug solubilizers interference study no interference was observed in UV spectrophometric analysis of Zaltoprofen in presence of employed solubilizers. Aqueous solubility of Zaltoprofen was found 0.028 mg/ml. The solubilizers s...
