摘要： This review is a historical look at work carried out over the past 50 years examining interactions of Toxoplasma with the host cell and attempts to focus on some of the seminal experiments in the field. This early work formed the foundation for more recent studies aimed at identifying the host and parasite factors mediating key Toxoplasma-host cell interactions. We focus especially on those studies that were performed in vitro and provide discussions of the following general areas: (i) establishment of the parasitophorous vacuole, (ii) the requirement of specific host cell molecules for parasite replication, (iii) the scenarios under which the host cell can resist parasite replication and/or persistence, (iv) host species-specific and host strain-specific responses to Toxoplasma infection, and (v) Toxoplasma-induced immune modulation.

摘要： 本文通过以下五个方面的论述,使我们对木材检验工作的工作台有了更深的了解。

关键词： 塑料包装袋   制袋   设计作品   分类   成品包装   产品种类   制作人  

摘要： 塑料包装袋种类繁多，规格不定，因此，设计和制作人员往往忽视了制袋方式，其结果是虽然设计稿精美，但制得的成品包装却不合人意，甚至成为废品。经验告诉我们，只有在了解常用包装产品种类的基础上，才能尽情发挥设计思路，杜绝不符合制袋工艺的设计作品，设计出实用、完美的成品包装。

摘要： 为了更好地维护妇女的合法权益和特殊利益,农十师一八二团根据实际情况,把维护妇女权益写进了女职工权益保护专项集体合同。

关键词： 食品企业   检验室   食品生产加工企业   个体工商户   生产许可证   加工设备   工艺流程   行业标准  

摘要： 食品生产加工企业是指有固定的厂房（场所），加工设备和设施，按照一定的工艺流程，加工、制作、分装用于销售的食品的单位和个人（含个体工商户），经审查合格后，依法取得生产许可证的企业。按照“取证”的要求，企业必须按规定设立实验室。在一定意义上，企业的检验室是检验该企业生产的食品是否达到国家标准（行业标准、地方标准、企业标准）、是否合格、是否准予出厂的最后屏障。但是，笔者在日常监管工作中通过调研发现，一些食品生产加工小企业的检验室却不能充分发挥作用。

关键词： HEALTH-INFORMATION-SEEKING   OLDER-ADULTS   INTERNET   BEHAVIORS   CORE  

摘要： A network approach was used to determine the overall supportive communication patterns constructed within the PTT psychosis support group in Taiwan, the largest bulletin board system in the Chinese-speaking world. The full sequences of supportive interactions were observed over a 21-year period from February 2004 to July 2006. The resits indicated that the most exchanged support types were information and network links. All types of supportive communication networks were relatively sparse, yet small groups of cliques with different provision of support types formed within the psychosis group. Most of the online supportive interactions exchanged at dyadic and triadic levels. The overall supportive network was highly centralized. The overall findings with implications for future studies were discussed.

关键词： Gene expression data   Gene selection   Sample selection   Particle swarm optimization   ALGORITHM   COMBINATION   PREDICTION   SARCOMAS   MODEL   QSAR  

摘要： Gene expression datasets is a means to classify and predict the diagnostic categories of a patient. Informative genes and representative samples selection are two important aspects for reducing gene expression data. Identifying and pruning redundant genes and samples simultaneously can improve the performance of classification and circumvent the local optima problem. In the present paper, the modified particle swarm optimization was applied to selecting optimal genes and samples simultaneously and support vector machine was used as an objective function to determine the optimum set of genes and samples. To evaluate the performance of the new proposed method, it was applied to three publicly available microarray datasets. It has been demonstrated that the proposed method for gene and sample selection is a useful tool for mining high dimension data. (C) 2009 Elsevier Ltd. All rights reserved.

关键词： 采用补救措施   退货   减价   修理   更换与重作  

摘要： 《合同法》违约责任主要分为三种形式,即继续履行、采用补救措施和赔偿损失。对采用补救措施中退货,减价及修理、更换与重作等形式的分析,可以得出采用补救措施实际不应作为独立的违约责任形式存在。《合同法》此举在一定程度上混淆了人们对相关规范性质的认识。

关键词： 音乐批评   存在方式   编者按   实践检验   评论员文章   导向   音乐期刊   编辑部  

摘要： 在音乐批评领域的各类文章中，“编者按”（包括评论员文章或编辑部文章）是常常为人们忽略，而实际上具有重要指向的一种音乐批评存在方式。其特征大致有五：一是以音乐期刊为阵地，于某篇文章（或作品）之上加一段文字，表示“编者”之思想、观念、意识、倾向；二是按语多为短文，短则寥寥数行，长亦千字左右，无拖泥带水之冗言，有快人快语之风格；三是出现概率极低，一种期刊，

关键词： 书面劳动合同   管理性强制规定   强制限度  

摘要： 法律关于劳动合同形式强制的规定属于管理性强制规定,未采用书面形式并不导致劳动合同不成立或无效,但是当事人应承担不利法律后果。随着劳动合同与劳动关系概念的区分,劳动关系多种证明手段的运用和集体合同法律制度的完善,劳动合同形式强制的力度将趋于弱化。
