THC(delta-9-tetrahydrocannabinol)是毒品大麻(marijuana)的主要心理活性成分,对白细胞介素-2(IL-2)激活NK细胞活性有非常显著的抑制作用。为了探讨THC抑制NK活性的机理,本实验用重组人IL-2-鼠NK细胞系统,从配体-受体结合的角度研究了THC对IL-2激活NK细胞活性的影响。结果表明:16μmol～32μmolTHC处理(台盼兰排除和~3H-TdR掺入法证明对NK细胞无毒性作用),能显著降低NK细胞与IL-2的特异结合;减少NK细胞表面的IL-2受体数目;但THC并不显著改变IL-2与受体结合的平衡解离常数(kd值);也不影响Tac单克隆抗体与β链Tac位点的结合。

根据实验数据建立了半再生重整分子水平反应动力学模型。模型包括305个C1-C12分子组分及864个化学反应,其中包括数十种烯烃及C6-C9所有芳烃异构体的生成与转化。以Langmuir-Hinshelwood-Hougen-Watson（LHHW）方程模拟反应速率,采用线性自由能关联方法（LFER）获取动力学参数,利用实验数据对模型进行了校正及检验。结果表明,芳烃脱烷基速率较低,应区分于加氢裂化反应;芳烃甲基迁移速率不容忽视,对C8＋芳烃产物分布有影响;模型对贫、富芳烃2种原料在10组不同反应条件下的C5＋液收、正构烷烃和环烷烃产率的预测较为准确,对C6-C9芳烃组分产率（质量分数）的预测偏差平均值小于3%。

在有色及黑色金属行业中,要生产出成本低,质量高的轧材,轧辊质量是最为重要的。由于轧辊质量与成本和轧材质量与成本之间有着紧密的关系,因而对辊面仔细彻底的检查,比合理的使用操作更为重要。辊面常规探伤的劳动强度较高,尤其是对肉眼看不到的缺陷,要有探测设备,专门的化学溶解技术,以及较长的检测时间。常规探伤是轧辊磨削加工之后的附加工作。

The availability of genomic sequences for human and diverse model organisms has allowed elucidation of the evolutionary origins of genes. For reproductive biologists, this breakthrough facilitates the analysis of genes expressed in reproductive tissues based on comparative genomic searches. We have identified a group of five orphan LGRs (leucine-rich repeat-containing G protein-coupled receptors) with sequence similarity to LH, FSH, and TSH receptors. Matching polypeptide hormones to their receptors indicated that the receptor for relaxin is LGR7 (Science 2002) whereas INSL3 activates LGR8 (jBC 2003). Furthermore, LH stimulates INSL3 transcripts in ovarian theca and testicular Leydig cells. INSL3, in turn, binds LGR8 expressed in germ cells to initiate the meiotic progression of arrested oocytes in preovulatory follicles and to suppress male germ cell apoptosis (PNAS 2004).
