Shallow basal root growth angle (BRGA) increases phosphorus acquisition efficiency by enhancing topsoil foraging because in most soils, phosphorus is concentrated in the topsoil. Root hair length and density (RHL/D) increase phosphorus acquisition by expanding the soil volume subject to phosphorus depletion through diffusion. We hypothesized that shallow BRGA and large RHL/D are synergetic for ...

BACKGROUND AND OBJECTIVES Hypoalbuminemia and hyperphosphatemia have been shown to be strong predictors of mortality in dialysis patients that might not be independent from each other. We prospectively investigated the relationship and interaction between serum albumin and phosphorus with all-cause mortality in an inception cohort of incident dialysis patients. DESIGN, SETTING, PARTICIPANTS, ...

Source-separated black water (BW) (toilet water) containing 38% of the organic material and 68% of the phosphorus in the total household waste (water) stream including kitchen waste, is a potential source for energy and phosphorus recovery. The energy recovered, in the form of electricity and heat, is more than sufficient for anaerobic treatment, nitrogen removal and phosphorus recovery. The ph...

Ten young adult cats, 6 intact males and 4 intact females, with reduced renal mass were randomized to receive either normal feline maintenance diet alone or diet plus phosphorus binder in a crossover design with each treatment period of 56 days in duration (Dietary Trial A). For Dietary Trial B, following a 3-month withdrawal period, 6 cats were placed on the intestinal phosphorus binder for 9 ...

1. Sodium phosphate was infused intravenously over approximately 2+ h and produced a mean linear rise in plasma phosphorus levels of 9.1 mg/100 ml. Twentyone infusions were performed in twelve control subjects and thirty-eight were carried out in thirty-two patients with disorders of calcium and phosphorus metabolism. 2. The fall in plasma calcium under these conditions was related to: a. The i...

abstract the increasing of yield per unit area is usually achievable by improving the soil fertility level through using (chemical) fertilizers. the purpose of the present research was to evaluate the 6 extraction methods including olsen, morgan, ammonium bicarbonate-dtpa, colwel, bray and mehlich 3 in order to specify a suitable extractant(s) for estimating available phosphorus through using 2...

BACKGROUND AND OBJECTIVES Higher morning serum phosphorus has been associated with cardiovascular disease (CVD) in patients with or without CKD. In patients with CKD and a phosphorous level >4.6 mg/dl, the Kidney Disease Improving Global Outcomes guidelines recommend dietary phosphorus restriction. However, whether phosphorus restriction influences serum phosphorus concentrations and whether di...

This research was performed to evaluate the utility of several serum and urine parameters as well as bone ash and plasma parathormone assay to diagnose and monitor diet-related osteopenia in growing pigs. Five diets were tested as follows: calcium-deficient, phosphorus-replete; moderate-deficiency of calcium and phosphorus; marked deficiency of calcium and phosphorus; calcium replete, phosphoru...

This thesis explores the potential of zinc, cobalt, and phosphorus to influence primary production in the subarctic North Pacific, the Bering Sea, and the North Atlantic Ocean. In the North Pacific and Bering Sea, total zinc concentrations were measured along a near-surface transect and in selected deep profiles. Zinc speciation was also measured with a novel anodic stripping voltammetry method...

It is now well established that the synthesis of the major protein constituents of milk takes place exclusively in the mammary gland, utilizing as building materials the free amino acids of the blood (1). The research of Aten and Hevesy (2), confirmed subsequently by other workers (3, 4), leaves little room for doubt that the precursor of the casein phosphorus is the inorganic phosphorus of the...
