本文认为,历史中心在当代城市中正逐渐成为以追求城市旅游经济为目标的"主题公园",这一做法值得商榷——其继承了过去陈旧的功能主义观念,自上个世纪60年代以来,被许多批评家广为诟病——其局限性在于太过概念化和实施不当,比如滥用城市规划的分区理论与技术,以及对居住空间的忽视。将当代城市视为并当作主题公园和高度专门化的城市区域的拼接物构筑起来,这将在一定程度上破坏城市真正的宜居条件。与之相反,历史中心可以作为一种"城市基础设施",在当今城市中扮演一个富有意义的、多重的、综合性的角色。

为了提高肿瘤治疗效果并最大程度降低其毒性,研究人员针对多种类型肿瘤正在研究如何根据患者个体情况化进行适应性治疗。随着现代辐照技术(如调强放疗)的引入,结合功能显像技术能够更精准地描绘治疗靶区的性能,为治疗适应创造了多种机会。根据功能性CT、MRI和PET显像结果,在治疗过程中随时调整放疗靶区,或明确原发肿瘤内部的亚区以优化放疗剂量策略。此外,借助解剖或功能显像还能够预测正常组织发生并发症的概率,如使用CT或PET显像来预测放射性肺炎。PET显像除了聚焦、监测实体肿瘤以辅助放疗,并调整治疗策略外,还能够验证质子束疗法的疗效。本文主要讨论放射肿瘤学中基于影像学的治疗适应的现状及其所面临的挑战。

Ag.obacterium radiobacter MTCC 8161 completely decolorized the Crystal Violet with 8 hr （10 mg.L） at static anoxic conditions. The decreased decolorization capability by A. radiobacter was observed, when the Crystal Violet concentration was increased from 10 to 100 mg.L. Semi-synthetic medium containing.1% yeast extract and 0.1% NH4C1 has shown 100% decolorization of Crystal Violet within 5 hr. A complete deg.adation of Crystal Violet by A. radiobacter was observed up to 7 cycles of repeated addition （10 rag.L）. When the effect of increasing.inoculum concentration on decolorization of Crystal Violet （100 mg.L） was studied, maximum decolorization was observed with 15% inoculum concentration. A sig.ificant increase in the activities of laccase （184%） and aminopyrine N-demethylase （300%） in cells obtained after decolorization indicated the involvement of these enzymes in decolorization process. The intermediates formed during.the deg.adation of Crystal Violet were analyzed by g.s chromatog.aphy and mass spectroscopy （g./MS）. It was detected the presence of N,N,N＇,N＂-tetramethylpararosarfiline, IN, N-dimethylaminophenyl] [N-methylaminophenyl] benzophenone, N, N-dimethylaminobenzaldehyde, 4-methyl amino phenol and phenol. We proposed the hypothetical metabolic pathway of Crystal Violet biodeg.adation by A. radiobacter. Phytotoxicity and microbial toxicity study showed that Crystal Violet biodeg.adation metabolites were less toxic to bacteria （A. radiobacter, P. aurug.nosa and A. vinelandii） contributing.to soil fertility and for four kinds of plants （Sorg.um bicolor, Vig.a radiata, Lens culinaris and Triticum aestivum） which are most sensitive, fast g.owing.and commonly used in Indian ag.iculture.
