Study and Application of Electrochemical Behavior of Calcium-ARS on a Mercury Film Electrode
      
The peak current was proportional to the concentration of calcium in the range of 5.0×10-8-4.2×10-5 mol L-1.
      
This method was applied successfully to determining traces of calcium in blood serum.
      
The interaction of water molecules with the calcium and phosphate sites at the HAP-water interface was also studied.
      
The regeneration of exhausted solutions of electroless nickel plating wood veneer was realized using soluble calcium salt to precipitate and remove phosphite and then using fluoride to remove residual calcium ions from the solution.
      
The effect of the pH value of the solution, treatment temperature and the molar ratio of calcium ions to phosphite ions on the removal efficiency of phosphite was investigated.
      
FUXW recombinant lentiviral vectors were produced by calcium phosphate-mediated transient cotransfection infected MNCs from ICR and C57 mice.
      
At the later stage of the developmental phase, Ca2+ was distributed in the tonoplast and vacuole phagocytosis, and the vacuole became the main calcium storage in this phase.
      
Protein, fat, fiber, dry material, ash as well as major microelements: calcium, kalium, zincum, sodium in the food were analyzed by standard methodology.
      
However, the calcium content in the forage is significantly less than the average of those in the wild plants.
      
It is suggested that the increase in calcium intake may contribute to the relief of low plasma calcium diseases of elephants in captivity.
      
Calcium carbonate crystals in scale samples were characterized by means of SEM and XRD.
      
The porous hydroxyapatite (HAP) for suspension polymerization dispersant was prepared using calcium carbonate and phosphoric acid as raw materials.
      
The preparation conditions for the HAP were optimized as follows: solid content of calcium carbonate aqueous suspension 90 g/L, concentration of phosphoric acid 1.0 mol/L, reaction/aging temperature 50°C, and aging time 3 h.
      
Inhibition of proliferation of osteosarcoma by nano calcium phosphates: potential hard tissue repair after tumor extraction
      
Spherical-or cylindrical-shaped nanosized calcium phosphate particles are considered as an integral part of biological hard tissues such as bone and tooth enamel.
      
The effects were increased with decreasing particle sizes, and the 20-nm sized calcium phosphate, the basic building blocks during bone/enamel formations, was the most effective inhibitor.
      
We used fibroin gel to control the biomineralization of calcium phosphate and obtained one kind of mineralized fibroin fiber with the length of 1-2 mm.
      
By comparing the biological properties of both materials, the following conclusions can be obtained: (1) The deposition of a calcium phosphate layer was not found on the surface of Ti-15Mo-3Nb, so it was bioinert.
      
Because the network of potassium titanate biological thin film could induce the deposition of a calcium phosphate layer, this showed that it had excellent bioactivity.
