22-oxacalcitriol suppresses secondary hyperparathyroidism without inducing low bone turnover in dogs with renal failure. (1/3106)

BACKGROUND: Calcitriol therapy suppresses serum levels of parathyroid hormone (PTH) in patients with renal failure but has several drawbacks, including hypercalcemia and/or marked suppression of bone turnover, which may lead to adynamic bone disease. A new vitamin D analogue, 22-oxacalcitriol (OCT), has been shown to have promising characteristics. This study was undertaken to determine the effects of OCT on serum PTH levels and bone turnover in states of normal or impaired renal function. METHODS: Sixty dogs were either nephrectomized (Nx, N = 38) or sham-operated (Sham, N = 22). The animals received supplemental phosphate to enhance PTH secretion. Fourteen weeks after the start of phosphate supplementation, half of the Nx and Sham dogs received doses of OCT (three times per week); the other half were given vehicle for 60 weeks. Thereafter, the treatment modalities for a subset of animals were crossed over for an additional eight months. Biochemical and hormonal indices of calcium and bone metabolism were measured throughout the study, and bone biopsies were done at baseline, 60 weeks after OCT or vehicle treatment, and at the end of the crossover period. RESULTS: In Nx dogs, OCT significantly decreased serum PTH levels soon after the induction of renal insufficiency. In long-standing secondary hyperparathyroidism, OCT (0.03 microg/kg) stabilized serum PTH levels during the first months. Serum PTH levels rose thereafter, but the rise was less pronounced compared with baseline than the rise seen in Nx control. These effects were accompanied by episodes of hypercalcemia and hyperphosphatemia. In animals with normal renal function, OCT induced a transient decrease in serum PTH levels at a dose of 0.1 microg/kg, which was not sustained with lowering of the doses. In Nx dogs, OCT reversed abnormal bone formation, such as woven osteoid and fibrosis, but did not significantly alter the level of bone turnover. In addition, OCT improved mineralization lag time, (that is, the rate at which osteoid mineralizes) in both Nx and Sham dogs. CONCLUSIONS: These results indicate that even though OCT does not completely prevent the occurrence of hypercalcemia in experimental dogs with renal insufficiency, it may be of use in the management of secondary hyperparathyroidism because it does not induce low bone turnover and, therefore, does not increase the risk of adynamic bone disease.  (+info)

Identification of a novel group of bacteria in sludge from a deteriorated biological phosphorus removal reactor. (2/3106)

The microbial diversity of a deteriorated biological phosphorus removal reactor was investigated by methods not requiring direct cultivation. The reactor was fed with media containing acetate and high levels of phosphate (P/C weight ratio, 8:100) but failed to completely remove phosphate in the effluent and showed very limited biological phosphorus removal activity. Denaturing gradient gel electrophoresis (DGGE) of PCR-amplified 16S ribosomal DNA was used to investigate the bacterial diversity. Up to 11 DGGE bands representing at least 11 different sequence types were observed; DNA from the 6 most dominant of these bands was further isolated and sequenced. Comparative phylogenetic analysis of the partial 16S rRNA sequences suggested that one sequence type was affiliated with the alpha subclass of the Proteobacteria, one was associated with the Legionella group of the gamma subclass of the Proteobacteria, and the remaining four formed a novel group of the gamma subclass of the Proteobacteria with no close relationship to any previously described species. The novel group represented approximately 75% of the PCR-amplified DNA, based on the DGGE band intensities. Two oligonucleotide rRNA probes for this novel group were designed and used in a whole-cell hybridization analysis to investigate the abundance of this novel group in situ. The bacteria were coccoid and 3 to 4 microm in diameter and represented approximately 35% of the total population, suggesting a relatively close agreement with the results obtained by the PCR-based DGGE method. Further, based on electron microscopy and standard staining microscopic analysis, this novel group was able to accumulate granule inclusions, possibly consisting of polyhydroxyalkanoate, inside the cells.  (+info)

Combination of fluorescent in situ hybridization and microautoradiography-a new tool for structure-function analyses in microbial ecology. (3/3106)

A new microscopic method for simultaneously determining in situ the identities, activities, and specific substrate uptake profiles of individual bacterial cells within complex microbial communities was developed by combining fluorescent in situ hybridization (FISH) performed with rRNA-targeted oligonucleotide probes and microautoradiography. This method was evaluated by using defined artificial mixtures of Escherichia coli and Herpetosiphon aurantiacus under aerobic incubation conditions with added [3H]glucose. Subsequently, we were able to demonstrate the potential of this method by visualizing the uptake of organic and inorganic radiolabeled substrates ([14C]acetate, [14C]butyrate, [14C]bicarbonate, and 33Pi) in probe-defined populations from complex activated sludge microbial communities by using aerobic incubation conditions and anaerobic incubation conditions (with and without nitrate). For both defined cell mixtures and activated sludge, the method proved to be useful for simultaneous identification and analysis of the uptake of labeled substrates under the different experimental conditions used. Optimal results were obtained when fluorescently labeled oligonucleotides were applied prior to the microautoradiographic developing procedure. For single-cell resolution of FISH and microautoradiographic signals within activated sludge flocs, cryosectioned sample material was examined with a confocal laser scanning microscope. The combination of in situ rRNA hybridization techniques, cryosectioning, microautoradiography, and confocal laser scanning microscopy provides a unique opportunity for obtaining cultivation-independent insights into the structure and function of bacterial communities.  (+info)

Reduced cytosolic acidification during exercise suggests defective glycolytic activity in skeletal muscle of patients with Becker muscular dystrophy. An in vivo 31P magnetic resonance spectroscopy study. (4/3106)

Becker muscular dystrophy is an X-linked disorder due to mutations in the dystrophin gene, resulting in reduced size and/or content of dystrophin. The functional role of this subsarcolemma protein and the biochemical mechanisms leading to muscle necrosis in Becker muscular dystrophy are still unknown. In particular, the role of a bioenergetic deficit is still controversial. In this study, we used 31p magnetic resonance spectroscopy (31p-MRS) to investigate skeletal muscle mitochondrial and glycolytic ATP production in vivo in 14 Becker muscular dystrophy patients. Skeletal muscle glycogenolytic ATP production, measured during the first minute of exercise, was similar in patients and controls. On the other hand, during later phases of exercise, skeletal muscle in Becker muscular dystrophy patients was less acidic than in controls, the cytosolic pH at the end of exercise being significantly higher in Becker muscular dystrophy patients. The rate of proton efflux from muscle fibres of Becker muscular dystrophy patients was similar to that of controls, pointing to a deficit in glycolytic lactate production as a cause of higher end-exercise cytosolic pH in patients. The maximum rate of mitochondrial ATP production was similar in muscle of Becker muscular dystrophy patients and controls. The results of this in vivo 31P-MRS study are consistent with reduced glucose availability in dystrophin-deficient muscles.  (+info)

Myocardial creatine kinase kinetics in hearts with postinfarction left ventricular remodeling. (5/3106)

This study examined whether alterations in myocardial creatine kinase (CK) kinetics and high-energy phosphate (HEP) levels occur in postinfarction left ventricular remodeling (LVR). Myocardial HEP and CK kinetics were examined in 19 pigs 6 wk after myocardial infarction was produced by left circumflex coronary artery ligation, and the results were compared with those from 9 normal pigs. Blood flow (microspheres), oxygen consumption (MVO2), HEP levels [31P magnetic resonance spectroscopy (MRS)], and CK kinetics (31P MRS) were measured in myocardium remote from the infarct under basal conditions and during dobutamine infusion (20 micrograms. kg-1. min-1 iv). Six of the pigs with LVR had overt congestive heart failure (CHF) at the time of study. Under basal conditions, creatine phosphate (CrP)-to-ATP ratios were lower in all transmural layers of hearts with CHF and in the subendocardium of LVR hearts than in normal hearts (P < 0.05). Myocardial ATP (biopsy) was significantly decreased in hearts with CHF. The CK forward rate constant was lower (P < 0.05) in the CHF group (0.21 +/- 0.03 s-1) than in LVR (0.38 +/- 0.04 s-1) or normal groups (0.41 +/- 0.03 s-1); CK forward flux rates in CHF, LVR, and normal groups were 6.4 +/- 2.3, 14.3 +/- 2.1, and 20.3 +/- 2.4 micromol. g-1. s-1, respectively (P < 0.05, CHF vs. LVR and LVR vs. normal). Dobutamine caused doubling of the rate-pressure product in the LVR and normal groups, whereas CHF hearts failed to respond to dobutamine. CK flux rates did not change during dobutamine in any group. The ratios of CK flux to ATP synthesis (from MVO2) under baseline conditions were 10.9 +/- 1.2, 8. 03 +/- 0.9, and 3.86 +/- 0.5 for normal, LVR, and CHF hearts, respectively (each P < 0.05); during dobutamine, this ratio decreased to 3.73 +/- 0.5, 2.58 +/- 0.4, and 2.78 +/- 0.5, respectively (P = not significant among groups). These data demonstrate that CK flux rates are decreased in hearts with postinfarction LVR, but this change does not limit the response to dobutamine. In hearts with end-stage CHF, the changes in HEP and CK flux are more marked. These changes could contribute to the decreased responsiveness of these hearts to dobutamine.  (+info)

Effect of zinc on adenine nucleotide pools in relation to aflatoxin biosynthesis in Aspergillus parasiticus. (6/3106)

The adenylic acid systems of Aspergillus parasiticus were studied in zinc-replete and zinc-deficient media. The adenosine 5'-triphosphate levels of the fungus were high during exponential phase and low during stationary phase in zinc-replete cultures. On the other hand, the levels of adenosine 5'-diphosphate and adenosine 5'-monophosphate were low during exponential phase of growth and high during stationary phase. The adenosine 5'-triphosphate levels during exponential phase may indicate higher primary metabolic activity of the fungus. On the other hand, high adenosine 5'-monophosphate levels during stationary phase may inhibit lipid formation and may enhance aflatoxin levels. The inorganic phosphorus content was low in a zinc-replete medium throughout the growth period, thereby favoring aflatoxin biosynthesis. The energy charge during the exponential phase was high but low during the stationary phase. In general the energy charge values were lower because of high adenosine 5'-monophosphate content.  (+info)

Human muscle performance and PCr hydrolysis with varied inspired oxygen fractions: a 31P-MRS study. (7/3106)

The purpose of this study was to use 31P-magnetic resonance spectroscopy to examine the relationships among muscle PCr hydrolysis, intracellular H+ concentration accumulation, and muscle performance during incremental exercise during the inspiration of gas mixtures containing different fractions of inspired O2 (FIO2). We hypothesized that lower FIO2 would result in a greater disruption of intracellular homeostasis at submaximal workloads and thereby initiate an earlier onset of fatigue. Six subjects performed plantar flexion exercise on three separate occasions with the only variable altered for each exercise bout being the FIO2 (either 0.1, 0.21, or 1.00 O2 in balance N2). Work rate was increased (1-W increments starting at 0 W) every 2 min until exhaustion. Time to exhaustion (and thereby workload achieved) was significantly (P < 0.05) greater as FIO2 was increased. Muscle phosphocreatine (PCr) concentration, Pi concentration, and pH at exhaustion were not significantly different among the three FIO2 conditions. However, muscle PCr concentration and pH were significantly reduced at identical submaximal workloads (and thereby equivalent rates of respiration) above 4-5 W during the lowest FIO2 condition compared with the other two FIO2 conditions. These results demonstrate that exhaustion during all FIO2 occurred when a particular intracellular environment was achieved and suggest that during the lowest FIO2 condition, the greater PCr hydrolysis and intracellular acidosis at submaximal workloads may have contributed to the significantly earlier time to exhaustion.  (+info)

Plasma 25-hydroxyvitamin D in growing kittens is related to dietary intake of cholecalciferol. (8/3106)

Vitamin D synthesis by growing kittens exposed to ultraviolet light is ineffective. Concentration of 25-hydroxyvitamin D (25-OHD) in plasma (the most useful index of vitamin D status) was measured in six groups each of seven kittens given a purified diet (12 g calcium and 8 g phosphorus/kg, calculated metabolizable energy = 20 kJ/g) that contained either 0.0, 3.125, 6.25, 12.5, 18.75 or 25 microg of cholecalciferol/kg diet. All kittens received these diets from 9 to 22 wk of age, and the two groups given the 0.0 and 3.125 microg cholecalciferol/kg treatments continued to receive the diets until they were 34 wk old. Total and ionizable calcium and phosphorus in plasma were not affected by treatments. No adverse clinical changes were observed or found on radiographic examination of the kittens at 22 or 34 wk of age. Plasma concentration of 25-OHD was linearly related (r2 = 0.99, P < 0.001) to dietary intake of cholecalciferol. Plasma concentration of 25-OHD in kittens given the diet without added vitamin D was significantly less at 22 wk than at 9 wk, whereas kittens receiving the diet containing 3.125 microg cholecalciferol/kg had significantly higher 25-OHD concentrations at 22 and 34 wk than at 9 wk of age. Kittens given the 6.25 microg cholecalciferol/kg diet had plasma 25-OHD concentrations at 22 wk > 50 nmol/L which is considered replete for humans. An allowance of 6. 25 microg (250 IU) of cholecalciferol/kg diet is suggested to provide a margin of safety.  (+info)

Dietary sources of phosphorus include milk products, egg yolk, legumes, nuts, and whole grains. 1. Diseases such as Crohns disease and celiac disease impair the bodys ability to absorb nutrients such as phosphorus. Phosphorus is a mineral that is vitally important to the normal metabolism of numerous compounds and (in solution) an acid that, with sulfur, must be neutralized by the base-forming ions of sodium, potassium, calcium, and magnesium. [PHOSPHORUS DEFICIENCY IN HUMANS?]. Its deficiency though is uncommon as … Severe phosphorus deficiency can manifest as widespread organ dysfunction. However a deficiency of phosphorus is rare as it is present in most foods. Phosphorus deficiency may cause bone diseases such as rickets in children and osteomalacia in adults. Phosphorus deficiency (hypophosphatemia) is rare in the United States and is almost never the result of low dietary intakes [ 1 ]. Phosphate is what you get when you combine the mineral phosphorus with oxygen. [Article in Swedish] ...
Root gravitropism may be an important element of plant response to phosphorus availability because it determines root foraging in fertile topsoil horizons, and thereby phosphorus acquisition. In this study we seek to test this hypothesis in both two-dimensional paper growth pouch and three-dimensional solid media of sand and soil cultures. Five common bean ( Phaseolus vulgaris ) genotypes with contrasting adaptation to low phosphorus availability were evaluated in growth pouches over 6 days of growth, and in sand culture and soil culture over 4 weeks of growth. In all three media, phosphorus availability regulated the gravitropic response of basal roots in a genotype-dependent manner. In pouches, sand, and soil, the phosphorus-inefficient genotype DOR 364 had deeper roots with phosphorus stress, whereas the phosphorus-efficient genotype G19833 responded to phosphorus stress by producing shallower roots. Genotypes were most responsive to phosphorus stress in sand culture, where relativeroot ...
ABSTRACT: Effects of phosphorus content (510 to 987 ppm) on the gelatinization and retrogradation of 6 potato cultivars (Benimaru, Hokkaikogane, Irish Cobbler, Konafubuki, Sakurafubuki, and Touya) were studied. Pasting properties were analyzed by RVA, thermal properties by DSC, and mechanical properties of the starch gels by TA. Phosphorus was positively correlated with swelling power (r= 0.84) and negatively correlated with solubility (r= 0.83). Phosphorus content showed significant effect on certain pasting properties of potato starch such as peak viscosity, breakdown, and setback. Phosphorus content showed a significant positive correlation with peak viscosity (r= 0.95) and breakdown (r= 0.90). Increasing concentration of phosphorus tends to decrease the setback.

During the course of this study, a better understanding of the water-sediment-phosphorus relationships of some shallow lakes in Central Florida was attempted. Column studies and batch experiments were used to investigate the effect of mechanical mixing on the release of phosphorus from bottom sediments collected from Lake Claire and Jessup. The particle size distribution and sensity distribution of the bottom sediments were studied and the release of phosphorus from each fraction was measured. the results indicated that dissolved oxygen, turbidity and phosphorus content in the water column increased by mechanical agitation. The total phosphorus released from smaller size particles seemed to be higher than phosphorus released from larger particles. Also, the least and highest density sediment particles showed ...

BACKGROUND: In kidney transplant recipients, persistent hyperparathyroidism leads to hypercalcemia and increased urinary phosphorus excretion. The calcimimetic drug cinacalcet effectively decreases parathyroid hormone (PTH) levels and corrects hypercalcemia in these patients. The purpose of the present study is to examine the effect of cinacalcet treatment on determinants of renal phosphorus reabsorption under steady-state conditions. STUDY DESIGN: Open-label prospective uncontrolled trial. SETTING & PARTICIPANTS: 10 stable kidney transplant recipients with persistent hyperparathyroidism. INTERVENTION: Cinacalcet, 30 and 60 mg/d, for 2 weeks. OUTCOMES & MEASURES: Changes in urinary phosphorus excretion in timed urine samples, intact and carboxy-terminal (C-term) fibroblast growth factor 23 (FGF-23), intact PTH, venous pH, and bicarbonate values at defined intervals over 24 hours. RESULTS: Cinacalcet decreased renal phosphorus excretion in the first 8 hours by 30% to 40%, but not from 8 to 24 ...

The first rooster assay determined the effects of increasing P intakes on excreta P retention values for corn. This assay involved feeding either 20 g of corn or 20 g of corn supplemented with increasing amounts of KH 2 PO 4 to provide total P intakes of 51 to 351 mg and non-phytate P intakes of 16 to 316 mg. The excreta P retention value for corn fed alone was 75% but decreased greatly when non-phytate P intakes were 76 mg or higher for the corn diets containing added KH ...
Phosphorus deficiency limits plant growth and development. To better understand the mechanisms behind how maize responds to phosphate stress, we compared the proteome analysis results of two groups of maize leaves that were treated separately with 1,000 µM (control, +P) and 5 µM of KH2PO4 (intervention group, −P) for 25 days. In total, 1,342 protein spots were detected on 2-DE maps and 15.43% had changed (P|0.05; ≥1.5-fold) significantly in quantity between the +P and −P groups. These proteins are involved in several major metabolic pathways, including photosynthesis, carbohydrate metabolism, energy metabolism, secondary metabolism, signal transduction, protein synthesis, cell rescue and cell defense and virulence. The results showed that the reduction in photosynthesis under low phosphorus treatment was due to the down-regulation of the proteins involved in CO2 enrichment, the Calvin cycle and the electron transport system. Electron transport and photosynthesis restrictions resulted in a large

Phosphorus balance. A positive phosphorus balance implies that phosphorus soil test levels will increase in the field over the course of the planning window. A rough rule of thumb is that soil test phosphorus will increase one pound per acre for every 10 pounds of phosphate applied per acre. This is a conservative estimate; on some fields 10 pounds of phosphate per acre will result in greater increases in soil test phosphorus.. Caution must be used in interpreting nutrient balances. In some cases the nutrient balance will be positive even when using a phosphorus-based application strategy. For example, a field may receive a phosphorus-based application rate to provide three years of phosphorus. If the application is applied in year one of the plan and then again in year four of a five-year plan the phosphorus balance will be positive because the removal window for the second application extends beyond the planning window of the five-year plan.. 3. Phosphorus balance for a five-year plan should ...

Hidden phosphorus is found in many foods,which makes it difficult to maintain a low phosphorus level when following chronic kidney disease diets. A renal diet can be followed better when chronic kidney disease patients know which foods have hidden phosphorus.
AUTHOR : -. CALL NO : S587.5.P56 S683 2017. IMPRINT : Boca Raton, Fla. : CRC Press, c2017. Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities..

Lotic systems act as nutrient buffers to receiving lentic systems. As streams transport allochthonous phosphorus through a watershed, the loads are modified in quantity and quality through biotic and abiotic mechanisms. Lotic systems are frequently dominated by periphyton, the attached benthic community consisting mainly of algae and bacteria. This community exhibits the ability to buffer phosphorus loads to receiving waters through several mechanisms including: biotic uptake, chemical precipitation, and mechanical filtration. Stream sediments, including clays, influence dissolved phosphorus concentrations primarily through equilibrium-driven sorption/desorption reactions. Additionally, suspended clays in aquatic environments are known to: modify food webs, influence species composition, and affect biotic integrity by altering the physical and chemical conditions. Given the influence that suspended clays exert upon aquatic systems, it was hypothesized that suspended clays would modify, either ...
Phosphorus even works in our bodies to efficiently use carbohydrates and fat. Phosphorus is a dietary Gal Friday...wearing a dozen hats and ensuring that essential functions go off without a hitch.. Phosphorus is the second most abundant mineral in our bodies (calcium is the first). Luckily, phosphorus is found naturally in many food sources. Its prevalence is highest in animal products (fish, chicken and beef), but it can also be found in milk products, peanuts, tofu and soybeans. The recommended daily phosphorus intake for a healthy adult is about 700mg/day, and if youre meeting your daily protein requirements, chances are youre stocked up on phosphorus too.. Perhaps counterintuitively, the concern we need to have with phosphorus is that we may on occasion get too much. While the RDA is 700mg, the upper limit of daily phosphorus is 4,000mg/day. Thats a huge disparity, and it would be tough to eat that much protein in a single day to account for 4,000mg of phosphorus. The way you quadruple ...

A pilot-scale, pre-anoxic-anaerobic oxidation ditch was used in this study to treat municipal wastewater with limited carbon source. A novel return activated sludge (RAS) pre-concentration tank was adopted for improving the phosphorus removal efficiency and the effects of RAS pre-concentration ratio were studied. Under the optimal operational condition, the suspended total phosphorus (STP) and the total phosphorus (TP) removal efficiencies were around 58.9% and 63.9% respectively and the effluent PO3-4 -P was lower than 0.8 mg•L−1. The reason is that with the optimal RAS pre-concentration ratio, nitrate is completely removed with endogenous carbon source and the secondary phosphorus release is strictly restrained in the pre-anoxic tank. Therefore, the anaerobic phosphorus release and the carbon source uptake by phosphorus accumulation organisms (PAOs) in the sludge, which are extremely important to the phosphorus removal process, can be fully satisfied. Furthermore, the oxidation-reduction ...
This study investigated the characteristics of denitrifying phosphorus removal bacteria by using three different types of electron acceptors as well as the positive role of nitrite in phosphorus removal process. Denitrifying phosphorous removal bacteria was enriched under anaerobic-anoxic (A/A) condition. To understand A/A sludge better, sludge from two other sources were also studied. These include sludges obtained from a lab-scale anaerobic-anoxic-aerobic (A/A/O) system and a local sewage treatment plant. Three types of possible electron acceptors (oxygen, nitrate and nitrite) were examined for their roles in phosphorus uptake. The results obtained indicated that oxygen, nitrate and nitrite were able to act as electron acceptors successfully. This observation suggested that in addition to the two well-accepted groups of phosphorus removal bacteria (one can only utilize oxygen to take up phosphorus, PO, while the other can use both oxygen and nitrate, PON), a new group of phosphorus removal ...

N2 - Mankind is taking advantage of numerous services by small shallow lakes such as drinking water supply, irrigation, transportation, recreational function and aesthetic values; however, eutrophication drives many of them to a deteriorated state. Internal loading of phosphorus (P) may often be the main reason why shallow lakes are unresponsive to watershed nutrient management programs. In this case, removal of sediments enriched in P is a possible method to reduce the internal P loading.In our study, we examined the changes in sediment P mobility and internal phosphorus loading after excavation of a 1-ha highly eutrophicated lake in Viljandi, Estonia. For that, we measured redox potential of the surficial sediments, ...

Phosphorus is a mineral that is found in many of our foods. For us humans, it is quite an important little mineral. It is one of the building blocks of our cells. In a complex mixture of phosphorus, oxygen, and hydrogen, it makes up half of the outer wall of the cell. It is also a vital part of the inside of the cell, allowing it to perform a variety of different functions. In the nucleus, both RNA and DNA are made with phosphorus, which holds DNA together like glue.. Phosphorus is also crucial to bone health, with 80 to 85% of our phosphorus being stored in our bones. Without phosphorus, our bones would be much weaker. Dietary phosphorus can influence bone production by signaling bone growth. This process is always working to make sure our bones stay healthy. Another role phosphorus plays in bone health is the effect phosphorus has on a hormone called PTH, which controls our bodys bone and calcium metabolism by increasing the bodys absorption of calcium and decreasing its loss.. Phosphorus is ...

A ban on phosphorus on our lawns is headed to the governor's desk. Legislation which would ban phosphorus as an ingredient in lawn fertilizers sold in Wisconsin is ready for Governor Jim Doyle's signature, with passage in the state Senate.. If . . . you absolutely need to have that nutrient, because of a phosphorus deficiency, or because you're starting a new lawn, you can in fact use a fertilizer containing phosphorus, said Monona Democrat, Senator Mark Miller . For everybody else, there's no need for phosphorus. The measure, aimed at protecting Wisconsin lakes from algae blooms, was supported by numerous environmental and conservation groups. Similar measures have been passed locally in communities including Madison and Marshfield, and several other states already have phosphorus fertilizer bans in place.. Phosphorus is one of many things that we need to deal, in Wisconsin's surface waters, said Elkhorn Republican, state Senator Neal Kedzie . As we become more ...
Phosphorus is required for both soft tissue and bone growth. Clinical signs of a deficiency include slowed growth for abnormal substance and unthrifty appearance. The calcium/phosphorus ratio should not be less than 1.2:1 for does and 2:1 for males. Grazing goats rarely develop a phosphorus deficiency due to their browsing phosphorus rich plants. Appropriate attention to calcium/phosphorus ratio is important to avoid promotion of urolithiasis. Additional information about phosphorus can be found at (Phosphorus).. ...
A variety of microorganisms like phosphorus solubilizing bacteria, phosphorus solubilizing fungi and arbuscular mycorrhiza are known to positively influence phosphorus uptake by plants. Such group of microorganism can become a part of integrated nutrient management systems for sustainable crop production.
The increase in soil test phosphorus differs for different soils; the same soil test phosphorus on different soils may support different concentrations of phosphorus in runoff. Soils with higher soil test phosphorus support higher concentrations of phosphorus in runoff. Soil-specific data are lacking for most Missouri soils.. The environmental soil test phosphorus, like agronomic soil test phosphorus, is an index procedure that extracts only a portion of the phosphorus in soil. The extraction procedure and the depth of soil sampling will dramatically effect the soil test value reported on a given soil. Caution should be used when quoting critical soil test levels; always note the extraction method and depth of soil sampling. Environmental soil test values from a Bray-I test on a 6-inch sample and a water extract on a 1-inch sample are not comparable.. Extracts being considered for environmental soil test phosphorus include water, Bray-I P, Mehlich-III P and iron-oxide strip P. Depth of soil ...
However, phosphorus has also received significant attention because of the potential for accelerated eutrophication in water bodies receiving excess P. Phosphorus is an essential nutrient for crops. A critical component of crop production is managing phosphorus for optimum economic benefit. However, if phosphorus is allowed to move off the land and get into water, it can be a pollution problem. Unlike nitrogen, excess phosphorus is not toxic but can result in eutrophication of water bodies. Eutrophication is the increased growth of undesirable algae and other aquatic plants, which limits the use of the water for drinking, fisheries, recreation, and industrial use. Historically, a major source of phosphorus in water was wastewater treatment plants. But as the amount of phosphorus getting into water from this source has been reduced, agricultural sources of phosphorus have gotten more attention. Manure in particular has been identified as a source of phosphorus to the environment. Agriculture has ...

This study investigated the effect of maturity class on phosphorus (P) balance in a soyabean-maize rotation in the West African moist savanna. Four soyabean varieties of different maturity classes were grown with or without P fertilizer followed by a maize crop. Soyabean stover P content averaged 1.77 kg ha(-1) compared with 5.13 kg ha(-1) in the grain. The late soyabean variety TGx1670-1F accumulated a significantly higher P in the grain (6.56 kg ha(-1)), and stover (2.57 kg ha(-1)) than the others. While P harvest index averaged 79%, P application increased grain P by 63-81% and stover P by 100% or more. When either soyabean grain or grain+stover was exported, P balance was negative and was not statistically different for varieties when no P was applied. At 30 or 60 kg P ha(-1), P balance was negative but significantly lower in TGx1670-1F compared with other varieties. Increasing Prate applied to soyabean significantly (p < 0.01) increased maize grain P by 35-66% in the second year. When P was ...

Phosphorus is an essential nutrient that allows life in water to flourish, but changes in phosphorus supplies are not well understood in remote watersheds. In mountain environments, remote watersheds contain critical high-quality water supplies and unique ecosystems, but excess phosphorus can diminish water quality by producing unfavorable aquatic species. Therefore, observed trends of increasing phosphorus concentrations in remote lakes and rivers in the US over the last two decades are a significant concern. Using the Uinta Mountains as a case study, we evaluated three different direct and indirect pathways for phosphorus increases in remote mountain watersheds that may explain observed increases over the last two decades. These mechanisms include atmospheric deposition of dust enriched in phosphorus and changing soil conditions (i.e., increasing soil temperatures and increasing soil pH), leading to greater land exports of phosphorus from runoff or erosion. In the Uinta Mountains, dust had

Keywords: Phosphorus, livestock production, phosphorus sources, phosphorus efficiency, availability, phytase.. Efficient production of livestock and poultry (and fish and pets) and the maintaining the good health of animals requires essential nutrients provided in appropriate amounts that are biologically utilisable. Dietary standards or allowances and thus phosphorus requirements for most animals have been established but are not always well-defined. In order to meet the requirements of the animal and without jeopardising animal health and production the phosphorus recommendations for most animals often include a safety margin and thus unneccessarily high rates of phosphorus are often recommended. Further, phosphorus sources, whether organic or inorganic, frequently have a wide range of bioavailability with those of lowest bioavailability being only utilised to some 50%. As a consequence, in many areas of the world with high livestock and poultry densities, the contribution of animal production ...
What is the issue? When babies are born too early (preterm), they have very low stores of the minerals calcium and phosphorus needed for healthy bones and growth. Human milk may not contain sufficient minerals for these babies.. Why is this important? Calcium and phosphorus are essential for healthy bones and normal growth and development. When a baby is born preterm and does not receive enough calcium and phosphorus, bone fractures and poor growth can occur.. What evidence did we find? We searched for evidence in April 2016 and identified one randomised controlled trial including 40 babies. Investigators reported a small decrease in the concentration of alkaline phosphatase (an enzyme involved in bone growth) among infants who had received calcium/phosphorus supplementation. We found no difference in growth between infants who had been given human milk supplemented with extra calcium and phosphorus and infants who had received no supplementation. One small trial provided the evidence, and we ...

A real steelmaking process involves many complex physical and chemical coupled phenomena such as oxidation, decarburization, dephosphorization, and slag formation.. Phosphorus is an element of representative impurities that should be kept as low as possible in conventional steel grades. Low phosphorus content steels are essential for steel applications where high ductility is required, such as thin sheets, deep drawn structures, pipelines, and automobile exteriors. Phosphorus ability to strengthen and embrittle ferrite imposes restrictions on the maximum phosphorus content for the aforementioned applications. The main source of phosphorus in steel is from the raw materials; thus, raw material selection is a way to maintain the phosphorus content within the desirable range.. In (BOF) oxygen steelmaking it is difficult to predict the distribution of phosphorus between slag and metal by direct application of models (listed in Table 1), even though a pseudo-steady state is usually attained between ...
Alum sludge from a Tampa water treatment plant was found to significantly reduce phosphorus release from anaerobic bottom sediments. The kinetics of phosphorus uptake by the sludge was evaluated in batch reactors. Further, the impact of the sludge on benthic organisms was determined in aquarium systems. Aquariums were set up with sediments and organisms from various lake habitats. Organisms were allowed to establish themselves and then test aquaria were dosed with alum sludge to cover the sediments. Benthic survival and heavy metal uptake were evaluated. Favorable phosphorus uptake was demonstrated in the batch reactors. The uptake kinetics were found to closely follow both Freundlich and Langmuir isotherms over a wide range of sludge dose and phosphorus concentrations. Benthic organisms typical of polluted environments were not adversely affected by the sludge additions. However, oligochaetes exposed to the sludge had elevated metal concentrations. Clean water organisms were somewhat less

This study vitalized the uncertainty and fuzzy rules consideration in the estimation of phosphorus loadings and eutrophication status of the hydrologic system namely detention pond using Fuzzy Logic (MATLAB). These methods were chosen to cater for the uncertainty of loading factors such as sediment and phosphorus inflow, inflowing discharge and pond storage volume. The average of phosphorus concentrations obtained from site investigation was 0.178 mg/L, hydraulic residence time was 1.77 year and the average annual hydraulic loadings was 694.70 m/yr, obtained based on the 12 years period (2000-2012). The results showed that the maximum and minimum of phosphorus loadings was 2.00 x 10-3 ton/year and 5.00 x 10-3 ton/year. Phosphorus loadings obtained from MATLAB fuzzy logic was 3.9 x 10-3 ton/year. The eutrophication status of the detention pond was investigated using Fuzzy Logic Approach, incorporating various fuzzy rules (MATLAB). This evaluation required the twinning usage of Vollenweider P-Loadings

The trials were carried out in calcareous and acidic soils. PFs were added at three levels (10, 20 and 30 mg kg-1) and OFs was applied at the rate of 10 t.ha-1. Results of this study showed that Ca-P was the predominant form of P in calcareous soil while Fe-P and Al-P were predominate in ...
The element phosphorus is used to make matches. Molecular phosphorus has two common forms. There is white phosphorus which is dangerously combustible and is used to make fireworks and weapons. The more stable red phosphorus is used on the side of any box of safety matches. When you strike the match against the red phosphorus, a small amount of it is changed to white phosphorus to ignite the match. But phosphorus has more important uses than starting fires. Life needs phosphorus. The average human body contains about 26.5 ounces (750 grams) of phosphorus. Most of it is in our bones.. Phosphate is a compound of phosphorus and oxygen. It combines with sugars in living tissue to form the backbone of DNA, which is the blueprint for life found in every living cell. Phosphate is also part of a complex organic chemical called adenosine triphosphate (ATP) found in every living organism. ATP releases energy so that cells can function. Life needs phosphorus and could not exist without it in an abundant ...
Total nitrogen and available phosphorus concentration of soils in three secondary forest fields aged 1, 5 and 10 years of age regenerating from degraded abandoned rubber plantation (Hevea brasiliensis) and a mature forest in the west African Rainforest belt in southern Nigeria were investigated in order to determine the trend of change in the properties of soil in secondary forest during the course of forest restoration from degraded deserted rubber plantation (Hevea brasiliensis). There was a continuous increase in the concentration of total nitrogen in the soil (both topsoil and subsoil). The concentrations of total nitrogen and available phosphorus in the topsoil are higher than the subsoil. The concentration of available phosphorus during the first five years of secondary forest regeneration increased, after which their values declined by the tenth year in both the topsoil and the subsoil. Should this trend of decline in the concentration of phosphorus continue phosphorus may become a ...

Research in WI has shown that cranberries require additions of phosphorus fertilizer for sustained productivity. However, trying to determine the right amount of phosphorus to add and when to add it is very difficult - one of the few aspects of crop management where cranberries have something in common with other crops. What makes the situation extra hard in cranberries is that programs of soil and tissue testing often give conflicting information - it is not uncommon to see soil test values of phosphorus in or above the normal range (20-80 ppm Bray P) and tissue phosphorus contents either at the low end of the normal range (0.10%) or below this value. Phosphorus availability in the soil is related to many things. In an established cranberry planting the moisture status of the soil (from the saturated conditions after winter flood water is drawn to the drier conditions of the summer) plays a role in phosphorus availability. Type of soil, whether a mineral, sandy soil, a classic sanded peat, or a

TY - CHAP. T1 - Calcium and phosphorus metabolism and the Parathyroid Gland. AU - Nwariaku, Ohwofiemu E. PY - 2006/1/1. Y1 - 2006/1/1. N2 - The parathyroid glands comprise a group of endocrine structures (usually 4 in number) that either hug the posterior surface of the thyroid gland or are in close proximity to it. Although exceedingly small in size, they play crucial roles in the maintenance of calcium and phosphorus balance. Their function spans a range of activities, including blood coagulation, modulation of membrane permeability, muscle contraction, neuromuscular excitability, and the regulation of various signal transduction processes within cells. Their importance to the surgeon is usually related to states of overactivity in which hypercalcemia may ensue. Occasionally, these glands also become important in surgical practices when a state of hypocalcemia results, as may occur after total thyroidectomy for goiter or neoplasia. The intricate control systems regulated by the parathyroid ...
This paper addresses the structural characteristics and phase transformation behavior of plain electroless Ni-P and Ni-P-Si3N4 composite coatings. Composite coatings were prepared using a low phosphorus electroless nickel bath containing 1 and 5 g/L submicron silicon nitride particles at pH 6.5 and temperature 85 +/- 2 degrees C. Deposition rate was around 6 mu m/h for both plain and composite coatings. The amount of silicon nitride particles codeposited in the Ni-P matrix is 3.5 wt.% (N1) and 4.5 wt.% (N2) with the addition of I and 5 g/L particles in the bath. Deposit surface composition analysis carried out by energy-dispersive analysis of X-ray (EDX) results shows that plain Ni-P and Ni-P-Si3N4 deposits are having around 3.5 wt.% phosphorus. The X-ray diffraction (XRD) patterns of Ni-P-Si3N4 coatings are very similar to that of plain electroless Ni-P coating in as-deposited condition. Presence of a single high intensity peak at 44.8 degrees 20 which corresponds to Ni(111) peak is present in ...
Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. The common element in EBPR implementations is the presence of an anaerobic tank (nitrate and oxygen are absent) prior to the aeration tank. Under these conditions a group of heterotrophic bacteria, called polyphosphate-accumulating organisms (PAO) are selectively enriched in the bacterial community within the activated sludge. These bacteria accumulate large quantities of polyphosphate within their cells and the removal of phosphorus is said to be enhanced. Generally speaking, all bacteria contain a fraction (1-2%) of phosphorus in their biomass due to its presence in cellular components, such as membrane phospholipids and DNA. Therefore, as bacteria in a wastewater treatment plant consume nutrients in the wastewater, they grow and phosphorus is incorporated into the bacterial biomass. When PAOs grow they not only consume phosphorus for cellular ...
Phosphorus is a chemical element with symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidised state, as inorganic phosphate rocks. Elemental phosphorus exists in two major forms-white phosphorus and red phosphorus-but due to its high reactivity, phosphorus is never found as a free element on Earth.. The first form of elemental phosphorus to be produced (white phosphorus, in 1669) emits a faint glow upon exposure to oxygen - hence its name given from Greek mythology, Φωσφόρος meaning light-bearer (Latin Lucifer), referring to the Morning Star, the planet Venus. The term phosphorescence, meaning glow after illumination, originally derives from this property of phosphorus, although this word has since been used for a different physical process that produces a glow. The glow of phosphorus itself originates from oxidation of the white (but not red) phosphorus- a process now termed ...
The oxidation and exchange reactions of simple phosphorus compounds and the behaviour of a range of low valent triphenylphosphine complexes of the transition metals in liquid hydrogen chloride at room temperature were studied by (^31)P nuclear magnetic resonance spectroscopy. When oxidation did occur, the phosphorus was oxidised from the +3 to the +5 oxidation state. In general, five co-ordinate fluorine containing phosphorus(V) species were produced from the oxidation of phosphorus(III) fluoride and four co-ordinate species of type PBr(_x)C1(_4-x)(^+) (O ≤ x ≤ 4) from the oxidation of phosphorus(ill) bromide or chloride. The (^31)P n.m.r. chemical shifts of the complete series PBr(_x)C1(_4-x)(^+) (O ≤ x ≤ 4) were recorded in solution for the first time, stabilised by tetrachloroborate anions in liquid hydrogen chloride. The protonation of a series of oxygen containing phosphorus (V) compounds in the solvent at room temperature was investigated using P n.m.r. spectroscopy. A measure of ...

TY - JOUR. T1 - Grasshoppers regulate N. T2 - P Stoichiometric homeostasis by changing phosphorus contents in their frass. AU - Zhang, Zijia. AU - Elser, James. AU - Cease, Arianne. AU - Zhang, Ximei. AU - Yu, Qiang. AU - Han, Xingguo. AU - Zhang, Guangming. PY - 2014/8/4. Y1 - 2014/8/4. N2 - Nitrogen (N) and phosphorus (P) are important limiting nutrients for plant production and consumer performance in a variety of ecosystems. As a result, the N:P stoichiometry of herbivores has received increased attention in ecology. However, the mechanisms by which herbivores maintain N:P stoichiometric homeostasis are poorly understood. Here, using a field manipulation experiment we show that the grasshopper Oedaleus asiaticus maintains strong N:P stoichiometric homeostasis regardless of whether grasshoppers were reared at low or high density. Grasshoppers maintained homeostasis by increasing P excretion when eating plants with higher P contents. However, while grasshoppers also maintained constant body N ...
In more severe cases, a person may die from the toxicity. [8] India and Japan banned the use of white phosphorus in 1919 after the United States, followed by Chinas ban on white phosphorus usage in match production in 1925. As an element, it generally exists as one of two main allotropes - white phosphorus or red phosphorus, but it can also exist as violet and black phosphorus. Background. The Occupational Safety and Health Administration (OSHA) has set the phosphorus exposure limit (Permissible exposure limit) in the workplace at 0.1 mg/m3 over an 8-hour workday. Yellow phosphorus has a simple chemistry; when combined with H2O and CO2 molecules from respiration and some amino acids such as lysine, bisphosphonates result. The White Phosphorus Match Act of 1912, signed by President William Howard Taft on April 9, 1912, required manufacturers who used white phosphorus to register with district collectors of internal revenue and to file periodic notices and returns; levied a tax of two cents per ...
Three barrows weighing 45.0 kg, fitted with simple T-cannulas in both the duodenum and terminal ileum, were assigned to diets in a 3횞3 Latin Square design experiment to determine the effects of two calcium levels (0.8% vs 0.4%) on phytase activity and nutrient balance in growing pigs. The control diet contained 0.8% calcium, with no added inorganic phosphorus (0.45% total phosphorus) and no added phytase. The two additional experimental diets contained microbial phytase (750 phytase units/kg) and supplied either 0.8% or 0.4% calcium. With added microbial phytase, ileal and total tract digestibility of total phosphorus were improved by 20.9 and 13.8 percentage units, respectively (p=0.01). The apparent duodenal and ileal digestibility of phytate phosphorus were increased by 51.8 and 49.7 percentage units. (p=0.001). Lowering dietary calcium in the presence of microbial phytase increased the digestibility of phytate phosphorus by an additional 10.9 (p=0.001) and 5.7 percentage units for duodenal ...
Weaned crossbred barrows (n=126) were used to investigate the effect of four different levels of a new Zymetrics Inc. phytase (100 Units (U); 500 U; 2,500 U; or 12,500 U) on low phosphorus corn-soybean meal diets. This tested the theory that supplementation of higher phytase amounts to a low phosphorus diet will increase bone strength as well as maintain growth performance at a higher rate than those of lower or no phytase supplementation. Pigs were adjusted to a common Phase I diet for two weeks post-weaning before allocation to 1 of 6 dietary treatments for 4 weeks. Increasing supplemental phytase showed a linear increase in ADG (p , .01) and also showed an linear increase in overall body weight (BW) during the growing and finishing stages of the experiment. Daily feed intake and feed efficiency showed a linear increase (p , .01) and overall breaking strength increased linearly with phytase supplementation. Gain to feed ratios in pigs with 2,500 U and 12,500 U showed better performance than ...
Southern pines are typically limited by nitrogen (N) and phosphorus (P) availability in the soil environment. While the absolute quantities of P in forests soils may be large, the concentration of inorganic P in the soil solution is typically very small (&60; 0.01 mg L&178;-1). A onetime application of just 56 kg P ha&178;-1 can substantially increase growth of pine stands over a 20 year rotation (Pritchett and Comerford, 1982&59; Allen et al., 1990). Phosphorus fertilization of Pinus radiata in New Zealand has also shown long-term effects on labile P pools in the soil which improved stand growth during the subsequent rotations (Ballard, 1978&59; Gentle et al., 1986). Identifying and quantifying the biologically available P pools in the soil environment will help foresters in making site-specific P fertilizer prescriptions. I examined soil phosphorus pools using the Hedley sequential fractionation procedure and Mehlich-3 soil tests in a long-term loblolly pine (Pinus taeda L.) fertilization ...

Phosphorus Rex is a supervillain in DC Comics. Phosphorus Rex first appeared in Batman #666 and was created by Grant Morrison. Phosphorus Rex is a fiery member of the Circus of Strange. After Mister Toad was apprehended by the Gotham City Police Department, Phosphorus Rex joined the Circus of Strange members Big Top, Siam, and a group of Professor Pygs Dollotrons into attacking the Gotham City Police Department which resulted in four police officers getting killed and six others ending up injured. Phosphorus Rex and the rest of the Circus of Strange were defeated by Batman and Robin. Batman later interrogated Phosphorus Rex into giving him the identity of the Circus of Stranges leader. What Phosphorus Rex told Batman led him to Professor Pyg. In The New 52 (a reboot of the DC Comics universe), Phosphorus Rex alongside Professor Pyg were seen as inmates of Arkham Asylum. At the time when Batman and Nightwing arrived at Arkham Asylum to capture a corrupt guard who ended up releasing the ...
Arbuscular mycorrhizal fungal inoculation improves Nauclea orientalis L. growth dan phosphorus uptake in gold mine tailings soil media
Downloadable (with restrictions)! Degraded groundwater, impaired swimming, fishing, algae and weed problem are often associated with eutrophication from phosphorus (P) loadings in surface and groundwater. The concentrated growth of poultry industry and over application of litter on pasture lands may lead to excessive nutrient loadings in surface and groundwater. The Cooperative Extension Service recommendation suggests that no poultry litter should be applied if the soil test P exceeds 300 pounds per acre, irrespective of the marginal costs and benefits associated with one more unit of litter application on that piece of land. The objective of this paper is to model the economics of P loadings from poultry litter and analyze the policy implications of Cooperative Extension Services recommendation on quantity restriction on litter applications with empirical evidence. The results indicate that there exists significant difference in the marginal values of soil between different soil series, indicating
The assumption that nitrogen enrichment caused by human activities is threatening biodiversity in Europe and North America may be false. A survey of herbaceous terrestrial ecosystems covering a gradient of decreasing nitrogen deposition from Western Europe to Siberia suggests that phosphorus, not nitrogen, is often the key element. In the 274 sites examined, many more endangered plant species persist under phosphorus-limited than nitrogen-limited conditions, so extra phosphorus is the more likely to cause species loss. Conservation policies biased towards reducing nitrogen enrichment are unlikely to succeed; rather, attention should focus on reducing phosphorus availability. On the cover, Great Vasyugan in Western Siberia, a peatland harbouring many plant species under P-limited conditions, some of which are shown on the cover. Main image: Wladimir Bleuten; inserts: Franziska Tanneberger. Nitrogen enrichment is widely thought to be responsible for the loss of plant species from temperate terrestrial
Apply manure less-than-annually at a nitrogen-based rate: Another method to prevent phosphorus buildup is to apply at a rate that meets the nitrogen needs of the crop, and then refrain from manure applications in following years until the excess phosphorus has been depleted by crop uptake. This method works best with rotations that include crops with adequate phosphorus uptake. Otherwise, it might take many years before manure could be applied again. For example, in some pasture systems, turkey manure applied using this method would receive 15 years worth of phosphorus. And some regions have regulations stating that no more than 5-years-worth of phosphorus can be applied at a time from manure ...

Phosphorus (P) is a particularly complex nutrient in the soil because large amounts can be ?locked? up making it unavailable to plants. Measurement of P in soil, and determining fertiliser requirements, are therefore difficult as not all P measured will be available for plant uptake. See Phosphorus factsheet for more detail.. Diffusive Gradient in Thin-Films (DGT) is a new method of measuring soil phosphorus and other micronutrient levels, with tests showing it to be a more accurate measure of the growing crops nutrient requirement than more conventional methods. DGT-P is different to standard measures of soil phosphorus as it reflects the capacity of the soil to supply P in the soil rather than to the concentration of phosphorus in an extract. The DGT-P method aims to ?mimic? the plant root by only measuring the phosphorus in the soil that is accessible to the plant.. ...
Phosphorus, an essential element for all living organisms, is a limiting nutrient in many regions of the ocean due to its fast recycling. Changes in phosphate (Pi) availability in aquatic systems affect diatom growth and productivity. We investigated the early adaptive mechanisms in the marine diatom Phaeodactylum tricornutum to P deprivation using a combination of transcriptomics, metabolomics, physiological and biochemical experiments. Our analysis revealed strong induction of gene expression for proteins involved in phosphate acquisition and scavenging, and down-regulation of processes such as photosynthesis, nitrogen assimilation and nucleic acid and ribosome biosynthesis. P deprivation resulted in alterations of carbon allocation through the induction of the pentose phosphate pathway and cytosolic gluconeogenesis, along with repression of the Calvin cycle. Reorganization of cellular lipids was indicated by coordinated induced expression of phospholipases, sulfolipid biosynthesis enzymes and a

Treated effluent discharged from municipal wastewater-treatment plants to the Assabet River in central Massachusetts includes phosphorus, which leads to increased growth of nuisance aquatic plants that decrease the rivers water quality and aesthetics in impounded reaches during the growing season. To improve the rivers water quality and aesthetics, the U.S. Environmental Protection Agency approved a total maximum daily load for phosphorus in 2004 that directed the wastewater-treatment plants to reduce the amount of total phosphorus discharged to the river by 2012. The permitted total phosphorus monthly average of 0.75 milligrams per liter during the aquatic plant growing season (April 1 through October 31) was reduced by the total maximum daily load to a target of 0.1 milligrams per liter by 2012, and the nongrowing-season limit was unchanged at 1.0 milligrams per liter.From October 2008 through April 2014, the U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental
This report describes a mathematical modeling and systems study of the eutrophication problem in Lake Balaton, Hungary. Since it is generally agreed that phosphorus exerts a major influence on the direction of trophic change within the lake, the work focused on the dynamics of the phosphorus level in the lake ecosystem over the period 1976-1979. The Balaton Sector Model (BALSECT) one of the three ecological models developed at IIASA for examining phosphorus dynamics and phytoplankton growth in the lake ecosystem, was used to simulate the basic biological and chemical interactions between phosphorus compartments in the aquatic environment. BALSECT also considers sediment-water phosphorus exchange and phosphorus transfer between the different basins of the lake by advective and wind-induced water flows.. ...
In this historical cohort study, incident chronic hemodialysis patients in the group that was treated with activated injectable vitamin D had a significant survival advantage over a comparable group of chronic hemodialysis patients who did not. These findings withstood adjustment for multiple confounders, several sensitivity analyses, stratified models, and an independent analysis to address the issues of confounding by indication and confounding by mineral levels that may have resulted from injectable vitamin D. Because injectable vitamin D use among chronic hemodialysis patients was not universal, we were able to examine the association between receiving injectable vitamin D and mortality in 49 multivariate strata, and in 48 of 49 strata, the benefits were significant. We suggested previously that chronic hemodialysis patients who are treated with paricalcitol, a specific injectable vitamin D analog with less calcemic and phosphatemic properties, have a significant survival advantage over ...
Discharge of wastewater containing excess amounts of nutrients such as phosphorus (P) cause eutrophication of the receiving waterbodies. The consequences related to eutrophication can vary in severity, from esthetical issues to medical threats. The increasing focus on P as a non-renewable resource and the necessity for recovering and recycling P from nutritious wastewater has made biological phosphorus removal (EBPR) in wastewater a more favorable method compared to chemical precipitation. EBPR is a complex process where several essential process conditions and prerequisites make Norwegian wastewater, which typically is diluted and low in nutrients, less ideal for EBPR.. In this study, the possibility of applying EBPR in a local and presumably typical Norwegian wastewater (Lerkendal wastewater) was examined. The objectives of this work were to characterize the unknown wastewater in terms of relevant substances according to EBPR, and perform batch experiments to assess the bio-P activity in the ...
Low soil P availability is a primary constraint to common bean (Phaseolus vulgaris L.) production in Latin America and Africa. Substantial genotypic variation in bean adaptation to low phosphorus (LP) availability has been linked with root traits that enhance the efficiency of soil foraging. The objectives of this study were to identify quantitative trait loci (QTLs) for P accumulation and associated root architectural traits, to facilitate genetic improvement and to reveal physiological relationships. Eighty‐six F5.7 recombinant inbred lines (RILs) were developed from a cross between G19833, an Andean landrace with high total P accumulation, and DOR 364, a Mesoamerican cultivar with low total P accumulation in LP conditions. A genetic map constructed with restriction fragment length polymorphisms (RFLPs), microsatellites, and PCR‐based markers covering 1703 centimorgans (cM) total genetic distance and all eleven linkage groups (LGs) was used for QTL analysis. Seventy‐one RILs were ...

If you have a lawn and want to protect Lake Tahoes water quality, one of the most important things you can do is avoid over-fertilizing. Fertilizers can leech into the ground water and eventually become runoff into the lake causing algae growth that affects our water quality and clarity.. Fertilizer is prohibited in the backshore and in stream environment zones basin-wide. However, in other areas on your property where fertilizer may be needed to help plants become established, your help is needed. The best times to add phosphorus to the soil is just before planting - especially with transplants. Use composts and organics as amendments to the soil, as these have good levels of available phosphorus for plants to use. Be sure to monitor phosphorus and pH levels in your soil to make sure you are not applying more than what is needed. You might want to consider having your soil tested annually. In fact, soil experts tell us that Tahoe soils have plenty of available phosphorus and adding phosphorus ...
Phosphorus (P) losses from agricultural land is a serious environmental issue because of the impact of P on freshwater eutrophication (McDowell, et al., 2001). The movement of P from soil to surface water is impacted by P input to soil and manure management practices that impact P transport processes. Twenty-one natural runoff plots were established to monitor the effect of time and method of composted beef feedlot manure application and feed P input on net losses of bio-available P and sediment in surface runoff. Reducing feed P inputs resulted in a 33% reduction in manure P content. Runoff losses of P were reduced in direct proportion to feed P inputs. Runoff volume and sediment losses were lowest in the year s of compost application and we observed that a longer time interval between compost application date and spring runoff season resulted in increase sediment, runoff and P loss. Bray-PI extractable soil P (0-15cm) increased from 27 ppm prior to compost application up to 400 ppm in direct
NPK Industries RAW Phosphorus - 2 oz RAW Phosphorus is an essential element for plant growth. Phosphorus itself is required for all life and is often a limiting nutrient for crops.
