噬病毒体

噬病毒体是一种能感染其它病毒,通过损害宿主病毒来完成自我复制的病毒。目前已经先后发现三种噬病毒体:Sputnik、Mavirus和OLV(有机湖噬病毒体)。大多数噬病毒体都在低级的生命形式如阿米巴变形虫中被发现。噬病毒体能抑制宿主病毒的增殖和裂解细胞的能力,并且噬病毒体只有在宿主病毒存在时才能增殖。噬病毒体的发现开启了一条新的探索病毒间相互作用的途径。本文主要就噬病毒体的发现过程、噬病毒体的基本特征及噬病毒体感染宿主病毒的机制进行概述。

A Practical Plan for Public Works of Art Heckman Summer School at Woodstock

The 1957 launch of Sputnik and the 1983 publication of A Nation at Risk shifted national education policy. Music educators promoted an “intrinsic value” of music philosophy following Sputnik and music advocacy through politics and public performances following A Nation at Risk. Examining the history of both the intrinsic value philosophy and advocacy reveals that music educators responded to Sputnik and A Nation at Risk by continuing to work within their existing language and practices rather than reacting to and transforming after either event. The political, social, and cultural contexts of these events may explain music educators’ responses.
