Objective To find out whether the TCP-PMMA cement can be used for artifical joint fixation .

Increasement of ATP production from adenine by Mucor;

The reaction time by using immobilized yeast was reduced 50% and the ATP formation was relatively increased 68% than that of free yeast.

Synthesis of Cyclotriphosphazene Hydroxy-Derivatation and Flame Retarding Modification of Polyurethane;

We synthesized a new imide polymer containing cyclotriphosphazene ring, the polymer decomposition temperature (PDT) of which is over 320℃ and the char yield at 850℃ is 77 % .

This article introduces the progress of these fire-and heat-resistant materials which contain cyclotriphosphazene for the first time.

The present study was to validate the experimental result showing that harvesting bone tissue from an adjacent vertebral body for bone graft followed by replacing the defect by β-tricalcium phosphate (TCP) plug could be a feasible procedure in lumbar interbody fusion procedure.

Experiments indicated that cerium ion which could not emit fluorescence was reduced to cerium ion which could emit characteristic fluorescence by ascorbic acid in water solution, while sodium triphosphate was added the fluorescence intensity of the system could be greatly enhanced.
