The extraction behaviour of zirconium(IV) from sulfuric acid medium has been studied with a binary mixture tri-n-octyl amine (TOA) and Cyanex923 (a four trialkyl phosphine oxides) in kerosene using novel liquid-liquid method. Quantitative TOA was by changing different parameters such as variation, extractant effect chloride ion concentration, temperature, metal concentration diluent effect, pH ...

Modification of teichoic acid through the incorporation of d-alanine confers resistance in Gram-positive bacteria to antimicrobial peptides (AMPs). This process involves the products of the dltXABCD genes. These genes are widespread in Gram-positive bacteria, and they are also found in a few Gram-negative bacteria. Notably, these genes are present in all soft-rot enterobacteria (Pectobacterium ...

BACKGROUND The 'phosphate-binding tag' (phos-tag) reagent enables separation of phospho-proteins during SDS-PAGE by impeding migration proportional to their phosphorylation stoichiometry. Western blotting can then be used to detect and quantify the bands corresponding to the phospho-states of a target protein. We present a method for quantification of data regarding phospho-states derived from ...

This study examined the relationship between preexercise muscle glycogen content and glycogen utilization in two physiological pools, pro- (PG) and macroglycogen (MG). Male subjects (n = 6) completed an exercise and dietary protocol before the experiment that resulted in one leg with high glycogen (HL) and one with low glycogen (LL). Preexercise PG levels were 312 +/- 29 and 208 +/- 31 glucosyl...
