Journal of Animal Ecology, Volume 94, Issue 4, Page 745-759, April 2025.Our study reveals how top predators influence mammalian interaction networks by increasing complexity and redistributing interactions through indirect effects. These findings imply the important role of top predators in structuring communities, offering novel insights into the conservation and management of mammal communities in northeastern China ...

慢性HCV感染者外周血单个核细胞IL-18和IFNAR1检测的临床意义
Zhongguo shiyan zhenduanxue, 2006 目的分析慢性丙肝（CHC）患者外周血单个核细胞（PBMC）白细胞介素18（IL18）mRNA的诱导表达及α干扰素受体1（IFNαreceptor1,IFNAR1）表达,评价慢性丙肝患者PBMC细胞免疫功能。方法脂多糖（LPS）体外刺激正常对照组和慢性丙型肝炎病毒（HepatitisCvirus,HCV）感染组病人PBMC,RTPCR检测干扰素治疗前后PBMCIL18mRNA水平的变化。同时RTPCR检测不同组PBMCIFNAR1mRNA水平的差异。结果治疗前干扰素应答组病人（n=12）和无应答组病人（n=

Dizhen xuebao我国地震地电场观测时的漏电干扰问题会影响到观测质量和地震监测效能。针对这一实际问题，本文提出了点源干扰源定位方法。该方法首先建立地表点源对地电场观测影响模型，根据模型计算点源对地电场观测的干扰幅度，然后求解干扰源相对于中心电极的位置。将定位方法应用于高邮地震台和汉王地震台实际干扰源排查工作中，定位结果与实际干扰源位置基本一致，测区外干扰源定位误差小于2%，测区内干扰源定位误差小于20 m，并对影响计算误差的因素进行了分析。两个台站的实际应用表明 ...

Veterinary Dermatology, Volume 35, Issue 6, Page 736-744, December 2024.Background – Topical therapy is preferred for otitis externa (OE) in dogs, and otic products commonly contain glucocorticoids that can be systemically absorbed and possibly interfere with diagnostic tests such as intradermal testing (IDT). Hypothesis/Objectives – To determine the effect of a long‐lasting otic solution containing mometasone furoate (MF)

Veterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Zhongguo shiyan zhenduanxue, 2008 目的探讨肝素抗凝剂对化学发光法测定HCG的影响,以验证是否可用肝素抗凝血进行检测来缩短检测时间。方法用肝素抗凝和普通真空采血管抽取20份患者标本进行对比测定,同时用高于抗凝管10倍浓度的肝素抗凝剂对20份样本中的高中低浓度的HCG样本进行干扰试验。结果肝素抗凝和普通真空采血管两组数据经配对资料t检验（P>0.05）,差异无显著性;高浓度肝素抗凝剂对高、中、低浓度的HCG干扰值均小于干扰试验对照组1.96s,最大干扰百分比不足0.9%。结论肝素抗凝剂对化学发光法测定HCG无影响,可用肝素抗凝血样进行检测。

Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Protected areas (PAs) are pivotal to biodiversity conservation, yet their efficacy is compromised by insufficient funding and management. So‐called other effective area‐based conservation measures (OECMs) present a paradigm shift and address PA limitations.

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Multifunctional landscapes that support economic activities and conservation of biological diversity (e.g., cattle ranches with native forest) are becoming increasingly important because small remnants of native forest may comprise the only habitat left for some wildlife species. Understanding the co‐occurrence between wildlife and disturbance
