Rare Metals, EarlyView.ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Effects of inhibitor targeting the EGFR/MEK signaling pathway on the growth and development of Echinococcus multilocularis and its molecular mechanism [PDF]
, 2016 泡状棘球蚴病(Alveolarechinococcosis，AE)是由泡状棘球绦虫(Echinococcusmulticularis，Em)幼虫引起的一种致命性的人畜共患寄生虫病。目前对于泡球蚴病的治疗方法十分有限，寻找新型药物靶点十分必要。EGF/EGFR信号通路调控细胞的多种生命活动包括增殖、分化、迁移等，本文在实验室前期研究的基础上，探讨了小分子抑制剂通过对泡球蚴EGF/EGFR介导信号通路作用，对泡球蚴生长发育的影响及其机制。 本文对EGFR抑制剂CI-1033 ...

An ultra-thin amniotic membrane preparation and its application as carrier in corneal epithelium tissue-engineering [PDF]
, 2016 目的：羊膜是目前应用最广泛的构建组织工程角膜上皮的载体。但在临床应用中发现，基于羊膜构建的组织工程角膜上皮在移植术后角膜的透明度恢复并不理想。目前认为，羊膜基质的纤维细胞层及疏松的海绵层可能是影响羊膜透明度的主要原因。因此，本研究对传统去上皮羊膜（DAM）进行改造，制备一种新型的超薄羊膜（UAM）载体，并评估其生物学及光学性质，同时探讨使用该种载体构建组织工程角膜上皮的可行性。 方法：本研究利用0.02%的EDTA去除失活羊膜组织的上皮细胞，并采用IV型胶原酶消化去除羊膜基质的纤维层及海绵层 ...

Enrichment and Resistance Mechanism of Aegiceras corniculatum to Gas Elemental Mercury [PDF]
, 2016 红树林是生长在热带、亚热带地区的木本植物群落，具有极为重要的生态价值和经济价值。红树植物具有较高的富集汞的能力，其叶与大气之间存在持续的汞交换过程。目前，关于红树植物对离子汞耐受性的研究已有很多，而有关红树植物对气态汞胁迫的响应及其耐受性机制的研究却鲜有报道。因此，本研究以桐花树（Aegicerascorniculatum）幼苗为材料，利用封闭通量箱测定其在饱和气态汞（Hg0）胁迫下的生理、解剖结构和亚细胞结构的变化，探究桐花树叶片与大气汞交换的昼间变化规律及其影响因素。探讨其对汞的富集和耐受机制 ...
