Background: Taiwan's primary community care network (PCCN) demonstration project, funded by the Bureau of National Health Insurance on March 2003, was established to discourage hospital shopping behavior of people and drive the traditional fragmented health care providers into cooperate care models. Between 2003 and 2005, 268 PCCNs were established. This study profiled the individual members in...
The synthesis of a new phenolphthalein azide derivative, which can be easily utilized in polymer analogous reactions, is presented. The subsequent cycloaddition reaction with propargyl-functionalized methoxypoly(ethylene glycol) yielded polymers bearing phenolphthalein as the covalently attached end group. In presence of per-β-cyclodextrin-dipentaerythritol, the formation of stable inclusion co...
Background: The aim of the study was to determine the maximal tolerated dose (MTD) of gemcitabine every two weeks concurrent to radiotherapy, administered during an aggressive program of sequential and simultaneous radiochemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC) and to evaluate the efficacy of this regime in a phase II study. Methods: 33 patients with his...
The article concerns with the prospects of using phenolphthalein test solution in practice surveying concrete and reinforced building structures planta. problem study is limits application on pH level determined (the indicator works only at 8≤rn≤10). There a need expanding application. In order to determine different zones we have modernize method by adding other indicators phenolphthalein. sta...
The use of natural materials began to be developed on a large scale in chemistry. Natural substances are safe use, easy find, and cheaper. Biological indicators volumetric titration the focus experts. This study presented visualization alkalimetric weak acid with strong base addition indicators. Hibiscus rosa-sinensis L. Clitoria ternatea flowers were used as for diprotic acid, namely oxalic ba...
