Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Study on the effects of down-regulating Annexin A3 expression on biological behaviors of lung adenocarcinoma and its molecular mechanism [PDF]
, 2015 肺癌是我国第一大癌症，其发病率和死亡率均居恶性肿瘤之首，严重危害人类健康。肺癌按组织学类型可分为鳞癌、腺癌、小细胞癌和大细胞癌。近年来，肺腺癌（lungadenocarcinoma，AdC）的发病率呈逐步上升趋势，且患者死亡率高、预后极差。癌细胞易转移是肺腺癌患者预后差的主要原因，因此，探寻肺腺癌转移的分子机制及其新的治疗靶标，对于提高肺腺癌患者预后意义重大。我们前期研究中，采用定量蛋白质组学技术鉴定出AnnexinA3（Anxa3）为一个新的肺腺癌转移相关分子 ...

Conservation Biology, EarlyView.Abstract Achieving global conservation policy goals requires the ability to set and measure progress toward science‐based targets for biodiversity. The species threat abatement and restoration (STAR) metric was developed to enable actors to set science‐based targets for species.

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.

Cloning and Stress Response of the Cold-Regulated Genes of Adenine Nucleotide Translocase 2, the Chaperonin Containing Tailless Complex Polypeptide α and Stearoyl-CoA Desaturase in the Mud Crab, Scylla paramamosain [PDF]
, 2015 腺苷酸转移酶(adeninenucleotidetranslocase,ANT)，属于线粒体转运蛋白超家族，是线粒体中最丰富的蛋白质之一，主要作用是介导ADP/ATP在细胞质和线粒体基质之间的运输。伴侣素包含T型复合体(thechaperonincontainingtaillesscomplexpolypeptideα,CCTα)是几乎存在所有生物体中的一类分子伴侣，负责细胞内蛋白的组装和折叠。内质网内的硬脂酰去饱和酶(stearoyl-CoAdesaturase,SCD)，是一类含铁离子的限速酶 ...

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.
