to evaluate the relationships between soil inorganic phosphorus p (pi) fractions, the soil p test and plant parameters such as plant p uptake, dry matter yield, tissue p concentra-tion and relative yield, glasshouse experiments and chemical analyses were conducted on 13 calcareous soils from six agricultural and seven adjacent bushland (virgin soil) sites. four rates of p (0, 15, 30, 60 mg/kg s...

While there is a considerable body of research on the abundance and behavior of inositol hexakisphosphate in soils, much less is known regarding its behaviour in aquatic systems. The observed physico-chemical behaviour of this organic P species suggests that in marine and freshwaters, it should be complexed and precipitated by major ions such as calcium, magnesium, iron or aluminium, and thus i...

introduction: the aim of this study was to evaluate the correlation between serum levels of ovarian and gonadotropin hormones, age and number of follicles with follicular alkaline and acid phosphatase activity in infertile women under controlled ovarian hyperstimulation. methods: after collection of follicular fluid and calculation of the number of follicles, the specific activity of alkaline (...

conclusions in conclusion, dietary counseling of patients on hd is mandatory. interventions that consider the socio-economic situation allow delivering important messages on foods with the least amount of p and adequate protein content, and they may be a successful strategy in targeting patients at a higher risk of hyperphosphoremia. results results showed serum p level was reduced in patients ...

A triazole-linked hydroxyethylimino conjugate of calix[4]arene () and its cadmium complex have been synthesized and characterized, and their structures have been established. In the complex, both the Cd(2+) centers are bound by an N2O4 core, and one of it is a distorted octahedral, whereas the other is a trigonal anti-prism. The fluorescence intensity of the di-nuclear Cd(ii) complex is quenche...

Pseudomonas putia'a oxidation of benzene affords cis-3,5-cyclohexadiene1,2diol (JJ which serves as a novel precursor for the syntheses of several natural products including (+)-pinitol, (+)-condunto1 F, D-(-)-myo-inositol 1,4,5-trisphosphate and Dmyo-inositol 1-phosphate. The versatility of this approach is further demonstrated by the preparation of other functionalised cyclitol derivatives, in...
