应用超声超微血管显像筛查颈动脉斑块新生血管的可行性 [PDF]
【目的】比较超声超微血管显像(SMI)和超声造影(CEUS)对颈动脉斑块新生血管的评价结果,探讨SMI作为颈动脉斑块新生血管筛查方法的可行性。【方法】患者60例,共109个斑块,使用SMI和CEUS检查评估斑块新生血管情况。【结果】在109个斑块中,SMI和CEUS检测结果一致的有101个。SMI的费用更低(150元vs.900元)。SMI的检测时间更短[(5.0±1.4)vs.(18.5±2.2)min ...

【目的】界定颈动脉内中膜厚度及其斑块分级在估测冠心病中的最佳预测值。【方法】用高频超声检测125例患者颈总动脉内中膜厚度、颈动脉分叉处内中膜厚度,以及颈动脉斑块分级,评价它们估测冠心病的作用,并用ROC曲线评价它们的诊断价值。【结果】冠心病组颈总动脉及分叉处内中膜增厚、斑块分级高,与对照组比较差异有统计学意义,P〈0.05;ROC分析显示颈总动脉及分叉处内中膜增厚、斑块分级均可估测冠心病,其曲线下面积分别为0.70、0.75、0.74;将颈总动脉分叉处内中膜增厚≥1.3mm,颈总动脉内中膜增厚≥0 ...

Obstruction of biodiversity conservation by minimum patch size criteria
Abstract Minimum patch size criteria for habitat protection reflect the conservation principle that a single large (SL) patch of habitat has higher biodiversity than several small (SS) patches of the same total area (SL > SS). Nonetheless, this principle is often incorrect, and biodiversity conservation requires placing more emphasis on protection of ...

CTLA-4Ig融合蛋白对ApoE基因缺陷小鼠动脉粥样 硬化的抑制作用
【目的】 探讨CTLA-4Ig融合蛋白对高脂饮食饲养的载脂蛋白E基因缺陷小鼠(ApoE-/-)动脉粥样硬化病变的抑制作用65377;【方法】 25只10周龄ApoE-/-小鼠,高脂饮食饲养4周后,随机取5只验证AS病变(对照组);剩余20只随机分为4组(每组5只),继续高脂饮食饲养,分别采用CTLA-4Ig65380;PBS65380;IgG1腹腔注射,第4组不予处理;8周后取小鼠主动脉进行病理学检查,检测AS相关指标,包括斑块面积/管腔面积比65380;血管内膜/中膜厚度比,斑块内脂质65380 ...

Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
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

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.
