The activity of Cre recombinase is predominantly detected in the midbrain, diencephalon and olfactory bulb in the SCC4.4-iCre transgenic brain. However, it only can be observed in the caudal part of the midbrain in the SCC2.7-iCre brains. The results suggest that CYP11A1 gene expression could be differentially regulated in different regions of the brain.

结果发现，4.4 kb与2.7 kb之CYP11A1启动子皆可使Cre重组酶表现於胚胎脑部，前者主要表现在中脑、间脑及嗅球，后者仅主要表现在中脑尾端，说明了CYP11A1在不同脑区表现所需的元素有所不同，可能有不同的调控机制。

We also provide basis for KB splitting and solve the KB splitting problem Gasser has referred to but failed to solve We systematically analyze the multiple factors which lead to reorganization: the status and environment of system, the status of cooperative members, the properties and requirements of users, the amount, frequency, temporal constraints, task-solving quality constraints, cost constraints and resource constraints of the task to be solved, and the resource status, etc. We also present and realize an open, multi-level and multi-stage model to reorganize dynamically the architecture.

系统地分析了引起重组的多方面因素：系统的状态、环境，协作成员的状况，用户的属性、要求，待解任务的数量、频度、时间约束、求解质量约束、求解代价、资源约束，及资源状况等；提出并实现了开放的、多层次和多阶段的体系结构动态组织模型。

The protein level of NF-kB in nucleus peaks at 8h after stimulating with LBP (200μg/ml). In addition, PDTC, an inhibitor of NF-kB, whose effective concentration for NF-kB inhibition without any toxicity on cells is up to 100μmol/L, can significantly block NO production induced by LBP.
