an experiment was conducted to evaluate the effect of replacing dietary limestone with mashhad power plant calcium-waste in combination with available phosphorus level on growth performance, tibial strength and blood alkaline phosphatase activity in broiler chickens. three hundred and eighty four male broiler chickens were used in a complete randomized design experiment with a 4×2 factorial arr...

With the advent of our ability to clone and express a foreign gene in the heterologous host, came a remarkable capability to make almost any protein in abundant quantity to be used as therapeutic or diagnostic agents. It quickly led to the realization that proteins made in different hosts are different in many ways, particularly in their post-translation modifications. In this review a variety ...

Due to the properties of tumor cell, the tumor establishes itself in the organ and grows there, so there is a competition between the tumor cells and host cell (normal cells) for nutrients. Evidences show that high dietary phosphorus increases the rate of protein synthesis and thus the cell number. So, other than oxygen, sulfur, the important element that both tumor cells and normal cells need ...

The activation of soil-fixed phosphorus is a long-term concern in soil science. In order to enhance the activation effect to soil-fixed phosphorus in red soil, different modified zeolite, through physical, chemical method and the associated both physics and chemistry, was used in this paper. The results showed as following: 1) the activated ability to soil-fixed phosphorus in red soil for modif...

The aim of this study was to determine the effect of mineral fertilization on the activity of alkaline and acid phosphatase and content of available phosphorus in soil under winter wheat cultivation. The fi rst factor of experiment was the fertilization with P, K, Mg, Ca and S in six levels: 1 (P, K, Mg, Ca and S), 2 (K, Mg, Ca and S), 3 (P, Mg, Ca and S), 4 (P, K, Ca and S), 5 (P, K, Mg, Ca), ...

An inductively coupled plasma atomic emission spectrometry (ICP-AES) method was developed for the determination of phosphorus in fertilizers. Total phosphorus, direct extraction available phosphorus (EDTA), and water-soluble phosphorus, reported as phosphorus pentoxide (P205), in 15 Magruder check fertilizers were measured by ICP-AES, and the results were compared with those obtained by the AOA...
