寻找传说中的“亚特兰蒂斯”

关于亚特兰蒂斯的传说,始于古希腊的哲学家柏拉图.在他的晚年著作《克里特阿斯》和《提迈奥斯》两本对话录中都有提及.根据柏拉图的描述,亚特兰蒂斯是一个拥有高度文明的古老大陆,并在公元前约1600年时被一场自然灾难毁灭,一夜之间沉入海底.从柏拉图时代到今天,人们从来没有停止过寻找亚特兰蒂斯的行动,一直从地中海找到了南极洲.更多的观点则认为亚特兰蒂斯根本就是一个传说,柏拉图只不过借它比喻雅典社会的价值观,不过这并不能阻止考古学家和历史学家的搜寻.

Toward a multiplexed serotyping immunoassay for foot-and-mouth disease virus.

Initial results demonstrating the feasibility of a multiplexed liquid array immunoassay for foot-and-mouth disease viral antigen detection and simultaneous serotype differentiation are presented. Serotype-specific antibodies from rabbit and guinea pig hyperimmunesera were isolated and prepared for use in a multiplexed, bead-based assay. The performance of all of the available antibodies as both capture and detector reagents was evaluated in the multiplexed system to establish a combination exhibiting the highest homotypic responses and lowest heterotypic reactions. The multiplexed assay was evaluated against inactivated cell culture supernatant samples of the same subtype as the virus used to raise the capture and detector antibodies. Distinct serotype differentiation was observed, except in the case of serotype SAT1. Subsequently, cell culture supernatant samples from a larger pool of viral subtypes were analyzed. Distinct serotype differentiation was obtained when analyzing cell culture supernatant samples from viral serotypes C, Asia, and SAT3, irrespective of the subtype. However, limitations of the current antibody pairs were realized in some inconclusive results obtained when analyzing samples from a broader range of O, A, and SAT2 subtypes. The results obtained in this initial study will be used to further optimize the assay using polyvalent or monoclonal antibodies and move toward the analysis of clinical samples.     

实施产后健康监测 及时发现病牛

牛群健康的一个重要理念就是早发现早治疗,早发现甚至比治疗本身更重要。对于泌乳牛,更要强调这个观念,因为耽误治疗不仅会降低治愈率,而且会导致产奶量下降,影响繁殖性能,围产后期发生的疾病尤为如此。尽管实施产后健康监测使我们在产后牛管理上取得很大进步,但还是经常漏诊早期发病牛,导致延误治疗。     

Toward a model for local stakeholder participation in landscape-level wildlife conservation

The conservation community is increasingly taking a landscape-level approach to wildlife conservation. This approach faces obstacles, including how to ensure transboundary wildlife conservation goals that can be realized through local management actions, and how and when to engage local stakeholders in landscape conservation planning processes. Currently, local stakeholder participation is not institutionalized within these processes. This paper examines the potential role of local stakeholders in landscape conservation. In this paper, we present a preliminary model of cross-level coordination that could facilitate development and implementation of conservation across social–ecological landscapes, highlighting the possible contributions of local stakeholders. The feasibility of this model is contingent on addressing a range of challenges associated with local stakeholder participation in extra-local conservation decisions. Ultimately, we present suggestions for future research examining the potential for a locally inclusive, participatory approach to wildlife conservation across complex landscapes.

WTO规则知多少?

说起世贸组织（ＷＴＯ），就要说到它的规则。而说起Ｗ的规则，一大堆的新名词扑面而来，什么非歧视原则、最惠国待遇、国民待遇、特惠制，什么原产地原则、进口许可程序、保障措施、政府采购规则，等等，还有许许多多的协议、协定、谅解，看起来，令人有些眼花瞭乱。因此，对不熟悉ＷＴＯ规则的人来说，需要对那些五花八门的规则做一番梳理，在深入学习每一项具体规则之前，对ＷＴＯ的规则体系有一个总体的了解，对各规则之间的关联大体明了。这就是本篇所想要说的。 ＷＴＯ规则是什么 简单地说，ＷＴＯ的规则就是各项协定，是ＷＴＯ全体成…
