Aspirin delays preterm birth in pregnancies at high risk for preterm pre‐eclampsia: evidence from randomized clinical trial in Asia

open access: yesUltrasound in Obstetrics &Gynecology, Volume 66, Issue 1, Page 24-32, July 2025.
ABSTRACT Objectives To investigate the impact of aspirin administration on the incidence of preterm birth, according to the type of delivery and gestational age at preterm birth, and to examine the hypothesis that aspirin delays preterm delivery. Methods This was a secondary analysis of a multicenter stepped‐wedge cluster randomized trial of a first ...

胎儿股骨长度与双顶径比值的临床意义 [PDF]

open access: yes, 1987
近年来,随着超声测量技术的发展,超声测量胎儿股骨长度被推荐采用于推算孕周(孕龄)与胎儿生长发育情况。作者等曾对妊娠25~42周孕妇进行181例次使用实时超声测量胎儿股骨长度与双顶径,所得结果与文献报导相符。由于超声显像普遍使用于围产期检测 ...

The Expression of PolySia/TriSia Associated Proteins and Genes on Developing Brain and the Effect of Dietary Sialic Acid Intervention in Piglets [PDF]

open access: yes, 2015
摘要 研究背景:唾液酸(Sialicacid,Sia)是一类九碳单糖神经氨酸的总称,在细胞表面发挥其多种生物学功能。在体内,Sia通常以游离唾液酸、聚唾液酸(多聚/寡聚)、唾液酸衍生物(糖蛋白,糖脂)这三种形式存在。多聚唾液酸(polySialicacid,ploySia),一种唾液酸残基通过α2-8键连接而成的线性聚合物,广泛分布于在哺乳动物神经系统中,它的主要蛋白载体是神经细胞粘附因子(Neuralcelladhesionmolecule,NCAM)。PolySia-NCAM在细胞迁移、神经突生长 ...

性染色体数目异常疾病诊断技术研究进展 [PDF]

open access: yes, 2018
性染色体数目异常疾病是一类严重困扰人类生活的综合征,患者多能生存,但常有性腺发育不全、多发畸形、不育等异常表现。该病无法治愈,经激素替代治疗等干预措施可有效缓解症状,但早期确诊严重依赖于相关临床诊断技术的发展。该文拟就现今常见检测性染色体数目异常技术的发展作一综述,比较各技术优缺点及评价其在临床诊断中的应用价值,以方便检验工作者科学合理地采用相关技术,为临床提供更为准确可靠的实验室依据,推进对该类疾病的诊治与研究。国家自然科学基金面上项目(81572084);;厦门市科技重大专项 ...

Study on Roles of Dlk2 in Skeletal Muscle Development [PDF]

open access: yes, 2015
Dlk2(Delta-like2homolog)属EGF样跨膜蛋白,与同家族成员Dlk1(Delta-like1homolog)高度同源。现有研究发现Dlk1在包括脂肪生成和肌肉生成在内的多个发育过程中发挥重要作用。但是目前对Dlk2的研究还主要限于脂肪生成过程,迄今为止尚未见Dlk2在骨骼肌生成方面的报道。 本研究首次考察了Dlk2在骨骼肌发育中的作用。首先,通过检测不同发育时期的鸡骨骼肌组织中cDLK2的表达水平,我们发现其在胚胎骨骼肌发育早期较高,而随发育的进行逐渐降低并在出壳后维持较低水平 ...

dissecting of the role of nucleoporin seh1 in mice schwann cell development [PDF]

open access: yes, 2016
真核生物的核膜隔开了遗传物质和细胞质,这使细胞可以调控核质转运来调控细胞的多种生命活动。核膜上的核孔是由多种核孔蛋白组成的复合体,是介导核质转运的唯一的通道。最新的研究表明,核孔蛋白还参与了细胞周期的调控和机体的发育过程,尤其是神经系统发育的调控。Seh1是核孔蛋白亚复合体Nup107-160的组成成分,属于核孔复合体骨架核孔蛋白亚类。Nup107-160复合体作为NPC的主要结构组分,由九个亚基组成,负责调节mRNA的出核以及NPC的组装和分拆。现代研究表明,在细胞系和酵母中敲除Nup107 ...
