this research investigate the potential of rhizobium leguminosarum b.v .phaseoli to improve growth and nutritional status of common bean (akhtar cultivar) at three levels of salinity of s0, s1 and s2 (0, 35 and 70 mm sodium chloride, or 0, 3 and 6 ds/m, respectively). the greenhouse experiment was conducted as a factorial design in randomized completely with three replications by using the ster...

BACKGROUND Hypophosphatemia is a common metabolic complication in patients receiving specialized nutrition support. We changed our previously reported dosing algorithm because the low dose no longer appeared to be effective at increasing serum phosphorus concentrations. The purpose of this study was to evaluate the safety and efficacy of a revised weight-based phosphorus-dosing algorithm in cri...
