Langenfeld, M. G. (University of South Dakota, Vermillion) and P. F. Smith. Phosphorus distribution in pleuropneumonia-like and L-type organisms. J. Bacteriol. 86:1216-1219. 1963.-Sterol-requiring and sterol-nonrequiring pleuropneumonia-like organisms, salt-requiring and salt-nonrequiring L forms, and their parent bacteria, were analyzed for total, acid-soluble, lipid, and nucleic acid phosphor...

Four size fractions of the sediment of six environments of the upper Paraná River floodplain were analyzed for carbon, nitrogen, and phosphorus contents and microbial respiration (oxygen consumption). Particle size did not affect nitrogen and phosphorus content or microbial activity, but did affect carbon content (F = 4.274, df = 3; 20, p = 0.020). The carbon concentration of ultra-fine particl...

BACKGROUND AND PURPOSE The purpose of this study was to assess the association of vitamin D deficiency and indices of mineral metabolism with subclinical carotid markers that predict cardiovascular events. METHODS Two hundred three community-dwelling adults (Northern Manhattan Study; age, 68 ± 11; age range, 50 to 93 years) had serum measurements (calcium, phosphorus, 25-hydroxyvitamin D, 1,2...

The effect of phosphorus supplementation to ammoniated rice straw was studied. The in vitro experiment was carried out following the first stage of Tilley and Terry method. The treatments consisting of four diets were A= 50% ammoniated rice straw + 50% concentrate (control), B= A + 0.2% phosphorus (P) supplement, C= A + 0.4% phosphorus (P) supplement, and D= A + 0.6% phosphorus (P) supplement o...

Information on riverine phosphorus (P) dynamics during typhoon storm events remains scarce in subtropical regions. Thus, this study investigates the spatial and temporal dynamics of riverine phosphorus in a headwater catchment during three typhoon events. Continuous sampling (3 h intervals) of stormwater samples and discharge data were conducted at five locations, which represent the upstream, ...

Background: Hyperphosphatemia remains a common problem in patients on maintenance dialysis and contributes to the development of secondary hyperparathyroidism. Current therapies for the treatment of hyperphosphatemia are frequently insufficient to achieve the recommended K/DOQI goal of maintaining serum phosphorus level between 3.5 and 5.5 mg/dl. Niacinamide inhibits intestinal sodium/ phosphor...

An overview of the forms of phosphorus species likely to be encountered in natural waters and the implications for the measurement of ®lterable and total phosphorus is given. Procedures reported in the literature for the storage and digestion of water samples for ®lterable reactive phosphorus (FRP), total ®lterable phosphorus (TFP) and total phosphorus (TP) measurements are summarised and the a...

The objective of this study was to locate chromosomes for improving water and phosphorus-deficiency tolerance of wheat at the seedling stage. A set of Chinese Spring-Egyptian Red wheat substitution lines and their parent Chinese Spring (recipient) and Egyptian Red (donor) cultivars were measured to determine the chromosomal locations of genes controlling water use efficiency (WUE) and phosphoru...

Tissue nonspecific alkaline phosphatase, promoting arterial calcification in experimental models, is a powerful predictor of total and cardiovascular mortality in general population and in patients with renal or cardiovascular diseases. For this study, to evaluate a possible correlation between serum alkaline phosphatase levels and endothelial function, assessed by strain gauge plethysmography,...

Recently, the inshore reefs of the Great Barrier Reef have declined rapidly because of deteriorating water quality. Increased catchment runoff is one potential culprit. The impacts of land-use on coral growth and reef health however are largely circumstantial due to limited long-term data on water quality and reef health. Here we use a 60 year coral core record to show that phosphorus contained...
