黄鳝具有性逆转的特点,为了找到与黄鳝性别调控直接相关的序列位点,分析黄鳝性别相关基因在雌雄中的序列差异,本实验选择了性别相关基因Dmrt3作为研究对象,通过比较该基因在雌雄性腺中的甲基化状态就可以分析出参与性别控制的具体位点。实验通过甲基化敏感的限制性内切酶Hpa II酶切黄鳝的雌雄性腺,根据已知的m RNA序列设计相关引物扩增酶切产物,同时与未酶切的对照组进行比较,分析差异条带并对实验结果进行验证。研究结果发现,Dmrt3-FR2扩增序列中,精巢是去甲基化状态,而卵巢是甲基化状态,可以推测该位点很可能与性别调控相关。本实验补充了从分子学角度研究黄鳝性别调控的不足,同时也验证了用甲基化手段研究黄鳝性别调控的可行性,为其他研究提供了理论依据。

Studies of Community-based question and answer services (cQA) have grown to be one of the emerging trends in Web information services. And one of the main tasks is to retrieve similar questions. To identify the fact that some questions with different expressions though may indeed have the same, or very similar, meaning, the similar questions are defined in syntactic, semantic and pragmatic aspects according to user retrieval intention. Five models including Language Model, Translation-based Language Model, Parser-based model, LDA and WordNet source-based model are selected as baselines. Integrated models which linearly combine WordNet, Stanford Parser and Language Model and further weighted by syntactic feature are proposed to integrate features of the three aspects. Experiment results show that our integrated models perform better than the basic models, especially when the linear combination of the WordNet model and the Stanford Parser model is weighted by syntactic information with proper noun phrases as representative. The integrated models are further verified by logistic analysis.
