免疫组化 CSA 法在检测子宫内膜石蜡切片 整合素 αν β3 中的应用 [PDF]
【目的】探讨免疫组织化学技术检测子宫内膜整合素αν β3 抗原的方法,为研究整合素α ν β3 在胚胎黏附、着床过程中的作用机制提 供方便。【方法】采用免疫组化 LSAB法和 CSA 法检测妊娠组和非妊娠组子宫内膜整合素α ν β3 抗原。【结果】用 CSA 法检测接受胚胎移植治 疗的不孕症患者子宫内膜石蜡切片中的整合素α ν β3 抗原,获得了阳性的结果,妊娠组整合素αν β3 表达明显高于非妊娠组。【结论】CSA 检测法 比 LSAB 法敏感性更高,特别适用于检测组织细胞表达低的抗原 ...

输卵管积水手术治疗可改善种植窗期子宫内膜白血病抑制因子和整合素αvβ3的表达
【目的】探讨输卵管积水手术治疗对改善子宫内膜白血病抑制因子(LIF) 和整合素αvβ3表达的意义。【方法】选择输卵管积水患者60例,输卵管阻塞患者30例,应用免疫组化方法测定输卵管积水患者手术治疗前后及阻塞组患者种植窗期子宫内膜LIF和整合素αvβ3的表达情况。【结果】LIF和整合素αvβ3在输卵管积水患者手术前种植窗期子宫内膜的表达水平明显低于阻塞组(P0.05),手术治疗前后子宫内膜种植窗期的LIF和整合素αvβ3的表达水平有统计学差异 ...

应用32P标记的克隆HBVDNA片段探针对30例原发型肝癌病人的肝内组织进行了DNA电泳转移Southern杂交。结果检出HBVDNA整合者21例(70%),其中癌组织整合者18例(60%),癌外组织整合者16例(53%),双份组织均整合者13例(43%)。杂交带分析发现,不同例和同例肝内不同组织的HBVDNA整合模式都不相同,提示整合具随机性并可能发生整合和/或侧翼序列的基因重排。由于探针含HBV基因组中1.4~2.8kb的DNA顺序,故结果实际反映S基因及其下游增强子的整合状况 ...

【目的】通过动物实验探讨子宫动脉栓塞术(UAE)对子宫内膜整合素β3表达含量的影响。【方法】48只健康雌性豚鼠随机分为对照组(n=12)及UAE组(n=36);UAE组内再随机分为A1、A2及A3三个亚组(每组n=12)。UAE组动物应用三丙烯微球(Embosphere,40~120µm及100~300µm)行双侧子宫动脉栓塞术。A1、A2、A3组动物分别于UAE后16~30d、31~45d及46~60d内获取子宫标本。各组动物均于排卵日后3d获取子宫标本 ...

A framework for integrating resilience indicators into risk assessments
Abstract Globally, ecosystems are increasingly threatened by climate change and human pressures, yet ecosystem risk assessments predominantly emphasize exposure to stressors while overlooking intrinsic ecosystem resilience—the capacity to absorb and recover from disturbances.

ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...

ABSTRACT Second/foreign language (L2) learning is not solely a cognitive/linguistic acquisition process but includes mixed emotional experiences. Understanding how these emotional experiences relate to resilience could help our understanding of how learners navigate fluctuations in emotions when learning an L2.

ABSTRACT Electrocatalytic CO2 reduction reaction (CO2RR) represents a pivotal pathway for the promotion of carbon neutrality and the preparation of highly valuable chemicals. To improve the product selectivity and catalytic efficiency of CO2RR, single‐atom catalysts (SACs) offering highly efficient atomic utilization rates and adjustable electronic ...

ABSTRACT The high‐value conversion of biomass platform molecules is a key pathway for substituting fossil resources with renewables and promoting sustainable green chemical manufacturing. However, conventional thermocatalytic processes suffer from harsh reaction conditions, high energy consumption, and poor selectivity, whereas photocatalysis enables ...
