This study reveals a shift in woody plant community assembly from competitive exclusion in early succession to habitat filtering in later stages within karst areas. Environmental distance (80.54%) contributed significantly more than geographical distance (9.95%), providing strong quantitative evidence that niche processes, particularly habitat ...

载脂蛋白E是机体内最主要的载脂蛋白,具有遗传上的多态性[1,2]。在分析胆囊结石的研究中发现载脂蛋白E基因多态性与胆囊结石具有一定的相关性[3,4]。本研究对2010年2月至2014年2月期间诊治的120例胆囊结石患者进行分析,采用聚合酶链式反应-限制性片段长度多态性分析患者载脂蛋白E基因型与胆囊结石的相关性,并分析不同载脂蛋白E基因型与患者血脂水平的关系 ...

ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

ABSTRACT Magnesium (Mg)‐based composites are regarded as promising lightweight materials with significant potential for structural applications. The structure–property relationships of bionic Mg‐based composites remain unclear. Herein, three honeycomb‐like Mg‐Fe composites are fabricated to uncover the underlying strengthening mechanisms.
