Problem statement: There is evidence that the type of fiber influences the development of nephrocalcinosis in rats, but the effect of pectin was unknown. Approach: The effects of dietary pectin and cellulose on kidney calcification were studied in female rats. The diets used contained either 0.4-0.6% phosphorus and either cellulose (10%, w/w) or pectin. The purified diets used were balanced for...

A field experiment was conducted in the 1998 dry season at Kadawa, Nigeria to determine the effect of different levels of nitrogen (0, 60, 120 or 180 kg N ha ), phosphorus (0, 20 or 40 kg P ha ) and irrigation 1 1 (0.6, 0.8 or 1.0 IW/CPE ratio) on nutrient concentration and accumulation in maize. The experiment was a split plot design with four replications, the main plot was nitrogen level x i...

Chlorophyll-a and nutrient concentrations were monitored at weekly intervals across 21 river sites throughout the River Thames basin, southern England, between 2009 and 2011. Despite a 90% decrease in soluble reactive phosphorus (SRP) concentration of the lower River Thames since the 1990s, very large phytoplankton blooms still occur. Chlorophyll concentrations were highest in the mid and lower...

A new fertilizer technology developed at Penn State University offers several potential benefits for turfgrass cultivation. The new technology employs a phosphorus buffering system (PBS), which , maintains a steady phosphorus concentration in the soil solution over time. The PBS has the size and consistency of sand (Fig. 1) and can be mixed with any soil media. Once charged with phosphorus, the...

this study was carried out to determine effects of phosphorus residual applied to wheat on vetch (vicia panonioca) growth, yields and some  soil  physical, chemical  properties in soil. the experiment was conducted with randomized completely block design in a field with three replications including four levels of p residual (applied for wheat p0, p15, p30, and p45 kg p2o5 in hectare) from tripl...

CONTEXT AND OBJECTIVE magnesium ion concentration is directly related and phosphorus ion concentration is inversely related to calcemia. The aim of this study was to evaluate the evolution of magnesium and phosphorus ion levels in patients undergoing thyroidectomy and correlate these with changes to calcium concentration. DESIGN AND SETTING prospective study at the Alpha Institute of Gastroen...

plaint. For, no sooner is it known that the doctor has pronounced some old gentleman to be suffering from a carbuncle, than the friends of the latter would assuredly hint at haviug his " affairs set in order." Statistics, however, do not show the apprehension to be well grounded, and neither have I in my small experience observed the mortality, amongst those who have suffered from it, to be so ...
