A HIGH incidence of phosphate urinary calculi in sheep has been associated with the feeding of rations containing dibasic potassium phosphate (Lindley et al., 1953; Elam et al., 1956, 1957). Further, Lindley et al. (1953) observed elevated plasma phosphorus levels under these conditions. Emerick et al. (1959) observed high plasma phosphorus levels in lambs subsequently afflicted with urinary mi...

T here is substantial epidemiologic evidence linking hyperphosphatemia and cardiovascular and all-cause mortality among dialysis patients (1,2). Therefore, control of hyperphosphatemia is a crucial element of the routine clinical care of dialysis patients. Theoretically, control of serum phosphorus levels can be achieved by the right combination of decreased dietary phosphorus intake, decreased...

The effects of phosphorus deficiency on carbohydrate accumulation and utilization in 34-day-old soybean (Glycine max L. Merr.) plants were characterized over a diurnal cycle to evaluate the mechanisms by which phosphorus deficiency restricts plant growth. Phosphorus deficiency decreased the net CO(2) exchange rate throughout the light period. The decrease in the CO(2) exhange rate was associate...

The impact of global phosphorus scarcity on food security has increasingly been the focus of scientific studies over the past decade. However, systematic analyses of alternative futures for phosphorus supply and demand throughout the food system are still rare and provide limited inclusion of key stakeholders. Addressing global phosphorus scarcity requires an integrated approach exploring poten...

An efficient method is developed for the synthesis of single crystalline fibrous phosphorus submicron materials. Via the chemical vapor deposition (CVD) technique, fibrous phosphorus fibers with diameters from ∼150 nm to 2 μm were prepared directly from amorphous red phosphorus. The as-prepared fibrous phosphorus exhibited interesting photocatalytic properties.

Acid phosphatase is believed to be important for phosphorus scavenging and remobilization in plants, but its role in plant adaptation to low phosphorus availability has not been critically evaluated. To address this issue, we compared acid phosphatase activity (APA) in leaves of common bean (Phaseolus vulgaris) in a phosphorus-inefficient genotype (DOR364), a phosphorus-efficient genotype (G198...

When blood undergoes glycolysis at 37 ~ C, in addition to the loss of blood sugar, there are accompanying changes in the inorganic phosphorus. This relationship has been investigated and reported by a number of authors (2, 8, 9, 10). They agree that during the first 4 hours of glycolysis, the inorganic phosphorus of the blood in normal individuals either remains at a constant level, or is only ...

1. Organic phosphorus is abundant in soil and its turnover can supply a considerable fraction of the phosphorus taken up by natural vegetation. Despite this, the ecological significance of organic phosphorus remains poorly understood, which is remarkable given the biological importance of phosphorus in terrestrial environments. 2. Of particular interest is the possibility that coexisting plant ...

OBJECTIVE The current data regarding the association between calcium and phosphorus and cardiovascular disease are lacking. The aim of this study was to explore whether dietary calcium and phosphorus intake and their serum levels are associated with the prevalence of coronary artery calcification (CAC) using cardiac computed tomography in asymptomatic participants without a history of chronic k...

BACKGROUND HS219 (40 mg chitosan-loaded chewing gum) is designed to bind salivary phosphorus as an add-on to available phosphorus binders. We performed a randomized, placebo-controlled, double-blind study to evaluate the efficacy and safety of HS219 in hemodialysis (HD) patients with hyperphosphatemia as an add-on to phosphorus binders. METHODS Sixty-eight HD patients who were maintained on c...
