Conservation Biology, EarlyView.Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

DNA Methylation and Non-small Cell Lung Cancer [PDF]
, 2010 Genomic DNA methylation is a major form of epigenetic modification. Hypermethylation could affect the binding of transcription factors to DNA and change the structure of chromatin resulting in silence of tumor suppressor genes, which plays an important ...

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.

The expression and clinical significance of SATB2 in Esophageal Squamous Cell Carcinoma [PDF]
, 2015 摘要 研究目的：食管癌在中国是一种高发的消化系统恶性肿瘤。由于解剖位置深、临床症状隐匿、早期症状不明显、易以多种路径转移、高位癌手术残留、术后容易复发以及放化疗不敏感等特点，食管癌预后较差。因此，进一步深入研究食管癌发生发展、侵袭转移以及预后评估因素的内在机制具有重要的意义。SATB1是富含AT序列结合蛋白的特殊家庭成员之一，已被证明影响众多肿瘤致瘤性的过程。SATB2与肿瘤的关系密切一直是研究的关注点，然而，其在食管鳞状细胞癌组织中的作用不清楚。本论文以食管鳞癌为研究对象，以SATB2为切入点 ...

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Zhongguo shiyan zhenduanxue, 2006 目的探讨血清谷氨酸脱氢酶（glutamate dehydrogenase,GLD）与肝移植患者预后的关系。方法应用德国临床化学学会推荐的速率法测定30例肝移植患者血清GLD活性并动态观察其变化的规律。结果对30例肝移植术中及术后早期患者血清GLD、ALT、AST、LDH活性进行连续监测。在术中供肝血流再灌注后,患者血清中此4种肝酶的活性开始明显上升。患者的预后与GLD升高的幅度及恢复至正常的时间的长短有关。预后不良的患者术后GLD峰值（均值5898.52 U/L）明显高于预后良好的患者（均值285.08

FoxO3 Inactivation Promotes Human Cholangiocarcinoma Tumorigenesis and Chemoresistance through Keap1-Nrf2 Signaling [PDF]
, 2016 许多人类肿瘤中存在PI3K/AKT过度激活，然而该通路的异常导致肿瘤形成的分子机理仍未充分阐明。FoxOs是受PI3K/AKT负向调控的转录因子，与肿瘤形成密切相关，但对于FoxOs调控肿瘤生长的机制尚不十分清楚。胆管癌是一类起源于胆道上皮细胞的恶性肿瘤，胆管癌患者对化疗敏感性差，但耐药机理尚未充分阐明。Nrf2的激活与胆管癌耐药性及病人不良预后密切相关。高度激活的PI3K/AKT能够激活Nrf2信号通路，但其中具体的分子机制尚不清楚。Keap1是连接Nrf2与Cul3的衔接蛋白 ...

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty
Conservation Biology, EarlyView.Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...
