Aldose-6-phosphate reductase (alditol 6-phosphate:NADP 1-oxidoreductase) was isolated and characterized from mature apple leaves (Malus domestica cv. Starkrimson). The enzyme was purified 79-fold. The enzyme catalyzed the following reversible reaction: d-glucose 6-phosphate + NADPH + H(+) right arrow over left arrow d-sorbitol 6-phosphate + NADP(+). No activity was detected when NAD(+) was subs...

calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. in this study, various formulations of calcium acetate tablets were prepared and their disintegrati...

The serum chloride and phosphate levels were measured and the chloride/phosphate ratios calculated in a group of eighty-four hypercalcemic patients. Although patients with hyperparathyroidism frequently had phosphate levels in the low normal range (less than 3 mg/100 ml) and chloride levels in the nigh normal range (greater than 102 mEq/L), they were nevertheless significantly different from th...

Hyperphosphatemia, which associates with adverse outcomes in CKD, is more common among blacks than whites for unclear reasons. Low socioeconomic status may explain this association because poverty both disproportionately affects racial and ethnic minorities and promotes excess intake of relatively inexpensive processed and fast foods enriched with highly absorbable phosphorus additives. We perf...

Hypophosphatemia is defined as a serum phosphate level of less than 2.5 mg/dL (0.8 mmol/L). Hypophosphatemia is caused by inadequate intake, decreased intestinal absorption, excessive urinary excretion, or a shift of phosphate from the extracellular to the intracellular compartments. Renal phosphate wasting can result from genetic or acquired renal disorders. Acquired renal phosphate wasting sy...

Osteomalacia is characterized by a low serum calcium and phosphate with elevated serum alkaline phosphatase. Osteomalacia may be caused by deficiency of vitamin D or phosphate deficiency. Malabsorption syndromes, renal failure and liver disease can result in vitamin D deficiency. Looser’s zone are linear areas of low density surrounded by sclerotic borders, which are a feature of osteomalacia. ...

Light intensity during growth affects the proportion of carbon dioxide fixed by the reductive pentose phosphate cycle relative to that incorporated via C(4) acids in acetate phototrophs of Rhodospirillum rubrum. With cells grown at high light intensity (9000 lux) the specific activities of ribulose-1, 5-diphosphate and propionyl CoA carboxylases were increased compared with cells grown at low l...

to evaluate the effects of some phosphorus solubilizing bacteria strains on yield and agronomic traits in local bean (phaseolus vulgaris l.) of guilan, different phosphate fertilizer rates were tested during 2014 growing season. this research was carried out in experimental field of agricultural and natural resource research center of guilan province as split plot arrangement based on randomize...

biofertilizer is a substance which contains living microorganisms which can use instead of chemical fertilizer in sustainable crop production. the effects of phosphate solubilizing bacteria; root endophytic fungi (ef) piriformospora indica, and arbuscular mycorrhizal fungus (amf) glomus mosseae on growth and nutrient uptake of sunflower plants grown in mixture with two clover species, persian c...

BACKGROUND AND OBJECTIVES High levels of fibroblast growth factor 23 are associated with mortality, CKD progression, and calcification in CKD patients. The aim of this pilot study is to assess whether a very-low-protein diet (0.3 g/kg per day) with a consequent low intake of phosphorus would reduce fibroblast growth factor 23 compared with a low-protein diet (0.6 g/kg per day) in CKD patients n...
