Male students in undergraduate introductory biology courses are outperforming females at test time, but it may be due to how exams are designed rather than academic ability. In addition, high-socioeco...
A revolutionary biochemistry textbook designed for the needs of students in allied health professions has been produced following collaboration between The University of Queensland (UQ) and The Univer...

HIV and AIDS Bridging the gap
2014/3/28
Africa labours under the strain of the largest HIV epidemic in the world, with infection rates in several countries reaching above 30 per cent of the general population, disproportionately concentrate...
South Asia has one of the fastest growing infection rates for HIV/AIDS of any region in the world. Once confined to pockets of people particularly vulnerable to infection such as sex workers and...
Modeling of the gap junction of pancreatic β-cells and the robustness of insulin secretion
pancreatic β-cells gap junctions synchronization robustness

Pancreatic β-cells are interconnected by gap junctions, which allow small molecules to pass from cell to cell. In spite of the importance of the gap junctions in cellular communication, modeling studi...
热点地区与GAP分析研究进展
热点地区 GAP分析 生物多样性保护
2009/9/9
生物多样性保护的优先性研究是目前资助机构和保护专家关注的热点，热点地区分析和GAP分析是进行生物多样性优先性分析的两种方法。热点地区分析是根据物种丰富度和特有度，探讨怎样以最小的代价，最大限度地保护区域的生物多样性。GAP分析综合考虑区域陆生脊椎动物物种、土地覆盖类型及土地所有权和保护状况等方面信息，在保护土地管理实践中，使具有代表性的植被类型、重要物种都得到保护。本文介绍了热点地区和GAP分析...
摘要为探索用GAP启动子（PGAP）取代AOX1启动子（PAOX1），在P. pastoris中组成型表达外源蛋白的可能性，应用PCR方法从毕节酵母染色体中扩增了GAP启动子，以其取代诱导型表达载体pPIC9K上的PAOX1，构建了组成型表达载体pGAP9K。将人血管抑制素（AS）基因重组于pGAP9K的多克隆位点，获得含AS基因的重组质粒pGAP9K-AS。转化P. pastoris GS115...
摘要应用Gap-Repair新技术，以pBR322为载体，在λ噬菌体Red重组酶的作用下，通过同源重组直接从大肠杆菌DY330染色体上亚克隆了长度为6.7 kb的包含Red重组酶基因的λ噬菌体左向操纵子基因序列。建立了一种能够随意在不同细菌宿主中转移的基于pBR322-Red的重组工程系统。为了验证pBR322-Red的生物功能，以大肠杆菌染色体上的galk基因为靶标，用Red介导的单链DNA重组...
采用免疫组织化学技术研究了在强光照和全黑暗条件下荒漠沙蜥（Phrynocephalus prezewalskic）视网膜内生长相关蛋白GAP-43的表达变化。结果表明，在正常光照条件下，视网膜内GAP-43 阳性表达部位主要存在于内网层;强光照条件下，GAP-43免疫染色部位主要出现在内网层、节细胞层和内核层的部分细胞核。在全黑暗条件下，在视纤维层和内网层呈阳性染色;提示视网膜在不同环境条件下GA...
