Kinetics of phosphate absorption in lactating dairy cows after enteral administration of sodium phosphate or calcium phosphate salts.

Walter Grünberg et al.

The British journal of nutrition, 110(6), 1012-1023 (2013-04-03)

Hypophosphataemia is frequently encountered in dairy cows during early lactation. Although supplementation of P is generally recommended, controversy exists over the suitability of oral P supplementation in animals with decreased or absent rumen motility. Since the effects of transruminal P

Sodium-dependent phosphate cotransporters and phosphate-induced calcification of vascular smooth muscle cells: redundant roles for PiT-1 and PiT-2.

Matthew H Crouthamel et al.

Arteriosclerosis, thrombosis, and vascular biology, 33(11), 2625-2632 (2013-08-24)

Elevated serum phosphate has emerged as a major risk factor for vascular calcification. The sodium-dependent phosphate cotransporter, PiT-1, was previously shown to be required for phosphate-induced osteogenic differentiation and calcification of cultured human vascular smooth muscle cells (VSMCs), but its

Ultraviolet and infrared absorption spectra of Cr2O3 doped-sodium metaphosphate, lead metaphosphate and zinc metaphosphate glasses and effects of gamma irradiation: a comparative study.

M A Marzouk et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 114, 658-667 (2013-07-03)

The effects of gamma irradiation on spectral properties of Cr2O3-doped phosphate glasses of three varieties, namely sodium metaphosphate, lead metaphosphate and zinc metaphosphate have been investigated. Optical spectra of the undoped samples reveal strong UV absorption bands which are attributed

An investigation of the immediate and storage effects of chemical treatments on Campylobacter and sensory characteristics of poultry meat.

H Meredith et al.

International journal of food microbiology, 166(2), 309-315 (2013-08-27)

Campylobacteriosis is the most common foodborne bacterial infection in developed countries and many cases are associated with poultry. This study investigated the immediate and storage effect of dipping inoculated poultry skin samples in trisodium phosphate (TSP, 10 & 14%, w/v)

Characterization of the interaction between chitosan and inorganic sodium phosphates by means of rheological and optical microscopy studies.

Luca Casettari et al.

Carbohydrate polymers, 91(2), 597-602 (2012-11-06)

The physicochemical and rheological properties of chitosan and two different inorganic sodium phosphate dispersions (NaH(2)PO(4) and Na(3)PO(4)) were investigated in order to elucidate the role of different factors, such as ratios between polymer and sodium inorganic phosphates, different pHs and
