1. The sodium salt of triphosphoinositide partitions in the upper polar phase in a biphasic chloroform-methanol-water system similar to that of Folch et al. (1957). 2. On the addition of 2mug.atoms of Ca(2+) or Mg(2+) per mumole of triphosphoinositide the phospholipid passes entirely into the lower non-polar phase as the dicalcium or dimagnesium salt. 3. When serum albumin is included in the bi...

Microporous ceramic material, based on β-tricalcium phosphate β-Ca3(PO4)2 with grain size 2–5 μm, pore smaller than 10 mm, and density 1.22 g/cm3 corresponding to ~40% of the theoretical (3.07 g/cm3) β-Ca3(PO4)2, was obtained from a powder mixture given molar ratio Ca/P = 1.5 after firing at 1100 °C. A homogenized synthetic dicalcium hydrogen phosphates 1 calcium citrate tetrahydrate Ca3(C6H5O7...

Abstract Egg consumption is very high throughout the world and with it comes enormous amount of waste eggshells. To reduce utilize these wastes, eggshell wastes were simply transformed to low- or high-purity calcium carbonate grades by washing, crushing, drying use as raw materials for producing highly valuable phosphate products. Low-purity grade was used prepare triple superphosphate using in...

Calcium phosphate bone cements (CPCs) with antibacterial properties are demanded for clinical applications. In this study, we demonstrated the use of a relatively simple processing route based on preparation of silver-doped CPCs (CPCs-Ag) through the preparation of solid dispersed active powder phase. Real-time monitoring of structural transformations and kinetics of several CPCs-Ag formulation...

Calcium phosphate cements (CPCs) use the simultaneous presence of several calcium phosphates phases. This is done to generate specific bulk and in vivo properties. This work has processed and evaluated novel multiphasic CPCs containing dual tricalcium phosphate (TCPs) phases. Dual TCPs containing α- and β-TCP phases were obtained by thermal treatment. Standard CPC (S-CPC) was composed of α-TCP,...

The effect of different binders for direct compression on tablet critical quality attributes was investigated. Dicalcium phosphate, lactose and microcrystalline cellulose were used as fillers combined with ten (10, 20 30% w/w). Binder properties linked to tensile strength via partial least square analysis. Tablets containing VA64F PH105 exhibited the highest which their compaction (specific wor...

Magnesium hydrogen phosphate (MHP, MgHPO4) recovered from swine manure was prepared as an alternative phosphorus (P) source. Conventional P additives, monocalcium phosphate (MCP), dicalcium phosphate (DCP), and tricalcium phosphate (TCP) were compared with the MHP in terms of growth and P availability by juvenile carp Cyprinus carpio. A basal diet as a negative control was prepared using practi...
