简介:
美国国立卫生研究院(NIH)汇集了许多世界级生命科学领域的专家,他们中有些曾获诺贝尔奖提名,有的本身就是诺贝尔奖的获得者,这些学术报告就出自他们之口。
报告的内容所涉及的范围很广,这其中要特别指出的是场次频繁的几个生命科学研究的焦点领域,如乾细胞、细胞凋亡、RNA 、线粒体等。报告为多媒体形式,更难能可贵的是还配有同步字幕。 这一讲就是关于乾细胞的。
题 目: Defining and Manipulating the Hematopoietic Stem Cell Niche
主讲者: David Scadden, M.D

字 幕: 英文讲座概要:
The Stem Cell Interest Group was established to enhance communication and to foster collaboration among scientists from varying disciplines interested in stem cells. Topics of interest include fundamental stem cell biology, ontogeny, gerontology, and the therapeutic potential of stem cells. The SCIG serves as an open forum for discussion and dissemination of knowledge about all aspects of stem cell biology
题 目:Outer Membrane Biogenesis in Gram-Negative Bacteria
主讲者:Thomas J. Silhavy, Ph.D
来 自: 普林斯顿大学

字 幕: 英文讲座概要:The outer membrane (OM) of Gram-negative bacteria functions as a protective barrier. It is unusual because the OM bilayer is asymmetric; the inner leaflet is composed of phospholipids, but the outer leaflet is made of lipopolysaccharide (LPS). Two kinds of proteins are found in the OM. Lipoproteins are inserted into the inner leaflet of the OM by posttranslationally attached lipid moieties. Integral OM proteins are Beta-barrel proteins (OMPs). All of the components of the OM are synthesized inside the cell. They must be transported to, and assembled in the OM in the correct orientation to maintain barrier function, and all of this takes place outside the cytoplasm where there is no obvious energy source, such as ATP.
