将鹅源新城疫病毒ZJI株全基因组cDNA克隆通过酶切切下包含T7启动子区域和转录载体的片段,将其自身环化后获得约6.5kb的质粒。设计引物,利用基因定点突变技术,在此质粒上T7启动子与NDV Leader序列之间突变插入额外的3个G碱基,将此突变最终引入到原基因组cDNA克隆中。应用RT-PCR技术从尿囊液中扩增NDV基因组F/HN基因区域部分片段,利用限制性内切酶BsmB I将扩增片段连接,最终将原cDNA克隆中相应片段替换下。测序结果表明,原基因组cDNA克隆中特定位置碱基插入突变成功,F/HN基因区域碱基突变均得以纠正。以上cDNA克隆的修饰与替换为该毒株的反向遗传研究打下了基础。

In arid and semi-arid regions, the availability of adequate water of appropriate quality has become a limiting factor for development. This paper aims to evaluate the potential for rainwater harvesting in the arid to semi-arid Faria Catchment, in the West Bank, Palestine. Under current conditions, the supply-demand gap is increasing due to the increasing water demands of a growing population with hydrologically limited and uncertain supplies. By 2015, the gap is estimated to reach 4.5 x 106 m3. This study used the process-oriented and physically-based TRAIN-ZIN model to evaluate two different rainwater harvesting techniques during two rainfall events. The analysis shows that there is a theoretical potential for harvesting an additional 4 x 106 m3 of surface water over the entire catchment. Thus, it is essential to manage the potential available surface water supplies in the catchment to save water for dry periods when the supply-demand gap is comparatively high. Then a valuable contribution to bridging the supply-demand gap can be made.

The available evidence,which derives from studies investigating mechanistic effects of tea,research on animal models as well as epidemiological studies and intervention trials in humans,suggests that compounds contained in tea may have the potential to aid in the prevention of depression or in its treatment as an addition to established therapies.A wide range of potentially antidepressive biological activities of tea components have been ***,the mechanisms of tea phytochemicals possibly capable of decreasing the risk of depressive symptoms are complex,multifaceted and not well *** pharmacological effects on circumscribed neurobiological systems may be produced not by individual tea components but rather by the synergistic action of various compounds on multiple pathophysiological mechanisms involved in *** epidemiological studies have generally demonstrated beneficial effects of tea consumption on mood and depressive symptoms,cross-sectional studies are unable to prove a cause-effect *** positive effects on mood could be firmly established,tea drinking could support mental ***,the moderate antidepressive effects observed in healthy people are not necessarily indicative of possible clinical effects in major depressive *** controlled intervention studies are needed to establish a causal relationship between bioactive compounds in tea and depression.

Tumor metastases present an often difficult to treat therapeutic challenge for cancer patients and their *** recent paper by the Kaplan group(Kaczanowska et al.)exploited the natural capacity of monocytes or a subset of monocytes to migrate to tumor sites and pre-metastatic niches to deliver IL-12 in a novel anticancer approach designed to stimulate local immune responses.1 This raises the possibility to simultaneously fight cancer on at least two critical fronts,(1)elimination of the primary tumor and(2)inhibition of newly developing pre-metastatic lesions.
