用核糖体工程技术二次开发海洋微生物菌株资源的研究

经对无活性的海洋来源放线菌B3054进行链霉素抗性筛选,获得了一株具有抗肿瘤活性的链霉素抗性突变株SY-1.从该突变株的发酵物中分离得到了4个活性化合物,其中1个为新天然产物.对该菌株突变前后的rpsL基因(编码核糖体蛋白S12)进行分析未发现发生突变,提示突变位点可能在核糖体的另外亚基上.实验结果表明,核糖体工程技术可用于无活性菌株资源的二次开发利用.     

He Ⅱ常流体粘度实验测量技术研究进展

目前还没有现成的理论可以对He Ⅱ粘度进行合理的说明和计算,在大多数情况下还只能依靠实验技术来满足其工程需要.本文对传统实验技术,目前出现的各种改进型实验技术进行了概述,事实表明不同的实验技术所得的结果之间偶有符合,但不能从根本上解决He Ⅱ粘度对实验技术的依赖性,目前的实验技术还无法提供He Ⅱ粘度数值的一致性结论.但是通过对He Ⅱ粘度与温度之间的变化趋势、数值的数量级等方面的分析,证明了He Ⅱ粘度在1.6 K～1.8 K之间形成了最小值区域.当温度继续低于1.6 K时,He Ⅱ粘度会迅速增加,同样在温度高于1.8 K时,随着温度的增加,He Ⅱ粘度也会迅速增加.     

ZnCl2-assisted Synthesis of ZnSe Polycrystal

A chemical-assisted element direct-reaction method is developed to synthesize ZnSe compound semiconductor material at a relatively low temperature (～1000 C). ZnSe polycrystal was obtained in the closed-tube systems with Zn-Se, Zn-Se-Zn(NH3)2Cl2, Zn-Se-NH4Cl and Zn-Se-ZnCl2. The as-synthesized samples were tested by X-ray diffraction (XRD), thermogravimetric analysis (TGA) and analyzed by thermodynamic numerical method. The results demonstrate that the synthesis efficiency is higher than 99.96% for Zn-Se-ZnCl2 system at around 1000 C for 3 weeks. It also exhibits that not only temperature, but also low apparent ratio of volume and surface area of the source materials and higher ZnCl2 content are required to achieve high synthesis efficiency. A SeCl transporting reaction synthesis process is proposed based on the thermodynamic analysis.

Tumor-Localized Administration of α-GalCer to Recruit Invariant Natural Killer T Cells and Enhance Their Antitumor Activity against Solid Tumors

Invariant natural killer T (iNKT) cells have the capacity to mount potent anti-tumor reactivity and have therefore become a focus in the development of cell-based immunotherapy. iNKT cells attack tumor cells using multiple mechanisms with a high efficacy; however, their clinical application has been limited because of their low numbers in cancer patients and difficulties in infiltrating solid tumors. In this study, we aimed to overcome these critical limitations by using α-GalCer, a synthetic glycolipid ligand specifically activating iNKT cells, to recruit iNKT to solid tumors. By adoptively transferring human iNKT cells into tumor-bearing humanized NSG mice and administering a single dose of tumor-localized α-GalCer, we demonstrated the rapid recruitment of human iNKT cells into solid tumors in as little as one day and a significantly enhanced tumor killing ability. Using firefly luciferase-labeled iNKT cells, we monitored the tissue biodistribution and pharmacokinetics/pharmacodynamics (PK/PD) of human iNKT cells in tumor-bearing NSG mice. Collectively, these preclinical studies demonstrate the promise of an αGC-driven iNKT cell-based immunotherapy to target solid tumors with higher efficacy and precision.
