Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

The effects of miR-30c-1-3p regulating group ⅡA secretory phospholipase A2(sPLA2-ⅡA)expression on the pathogenic mechanism of atherosclerosis [PDF]

open access: yes, 2015
动脉粥样硬化(Atherosclerosis,AS)是急性冠脉综合症、脑卒中等众多心脑血管疾病共同的病理基础。sPLA2-ⅡA在动脉粥样硬化病变处含量明显增多、活性显著增强,同时伴随中性粒细胞的增多。sPLA2-ⅡA以酶的催化水解作用和作为致炎因子的促炎症反应双重生物学作用参与AS发生发展的各个阶段。 MicroRNA(miRNA)是近年发现广泛存在于真核细胞中的高度保守的、非编码单链小分子RNA,具有最广泛的基因调节功能,参与机体多种生理、病理过程的调控。 我们运用miRNA靶基因预测软件发现miR ...

CT imaging anatomy of myocardial bridge-mural coronary artery and its relationship with atherosclerosis [PDF]

open access: yes, 2015
研究背景:心肌桥-壁冠状动脉(MB-MCA)是一种先天性冠状动脉解剖变异,一直被认为是种良性病变。一般情况下,不引起临床症状,但可能出现心肌缺血、心律失常、心肌梗死及猝死等临床表现。明确MB-MCA的形态学特征及其与冠状动脉粥样硬化之间的关系,为相关疾病的诊断及治疗提供解剖依据。 目的:(1)应用64排多层螺旋CTA观察并测量MB-MCA发生率及其形态学特征;(2)探讨左前降支心肌桥(LAD-MB)与冠状动脉粥样硬化的关系。 实验方法:(1)回顾性分析本院2013.05-2014 ...

声辐射力脉冲(ARFI)成像技术在评估颈部血管斑块的价值分析 [PDF]

open access: yes, 2017
目的:对声辐射力脉冲(ARFI)成像技术在评估颈部血管斑块的价值进行分析。方法:回顾性分析2013年6月-2016年6月于本院医治的缺血性脑卒中患者114例为研究组,同期选取于我院检查的健康人群104例为对照组。两组均予以ARFI成像技术检查,测量记录斑块剪切波传播速度(SWV),观察两组斑块检出率,各类型斑块SWV均值,两组各类型斑块分布情况。结果:研究组共114人,检出有斑块的79例,共检出163个斑块,其中强回声36个、低回声51个、等回声31个、混合回声45个;对照组共104人 ...

64排螺旋CT结合血清白细胞介素6(IL-6)检测对判定冠状动脉斑块稳定性价值的研究

open access: yesZhongguo shiyan zhenduanxue, 2009
目的本研究通过64排螺旋CT检测各型冠心病中软斑块、混合斑块(均为不稳定斑块/易破斑块)、钙化斑块(稳定斑块)的分布结合血清IL-6的检测,从临床的角度探讨其对冠脉斑块稳定性的判别价值。方法选用2007年4月至2008年8月本院89例住院接受冠脉造影的患者,进行64排螺旋CT冠脉造影检查和血清IL-6的检测。纳入本研究的患者根据临床诊断分为三组:正常对照组、稳定型心绞痛组(SAP、急性冠脉综合征组(ACS)(不包括急性ST段抬高的心肌梗死)。据64排螺旋CT检查根据斑块性质分为四组:(正常对照组 ...

弗明汉危险评分在无症状老年人颈动脉易损斑块筛查中的价值研究 The Value of Framingham Risk Score for Screening Carotid Vulnerable Atherosclerotic Plaques in the Asymptomatic Elderly

open access: yesZhongguo cuzhong zazhi, 2019
目的 探讨弗明汉危险评分(Framingham risk score,FRS)在无症状老年人(≥60岁)颈动脉易损斑 块筛查中的价值。 方法 根据颈动脉粥样硬化斑块的3D MR管壁成像特征,将受试者分为有易损斑块组和无易损斑 块组,计算每位受试者的FRS并比较两组之间FRS的差异。采用单因素Logistic回归,计算FRS在判别颈 动脉易损斑块时的OR 和95%CI。采用ROC曲线分析FRS对颈动脉易损斑块的判别能力,并确定合适的 截断值。 结果 共纳入134例受试者,平均年龄72.3±5.5岁 ...

The Role of BIN1 in Alzheimer’s Disease [PDF]

open access: yes, 2015
阿尔茨海默症(Alzheimer’sdisease,AD)是与年龄相关的神经退行性疾病,其主要的病理学特征为由β-淀粉样蛋白(-amyloid,Aβ)聚集产生的老年斑(senileplaues,SP)以及由异常磷酸化的tau蛋白组成的神经纤维缠结(neurofibrillarytangles,NFTs)。Aβ是由淀粉样前体蛋白(-amyloidprecursorprotein,APP)经过β-分泌酶和γ-分泌酶的依次顺序剪切而产生 ...
