Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 376-384, March 2026.ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

Zhongguo shiyan zhenduanxue, 2017 目的探讨慢性粒细胞白血病（CML）中细胞遗传学的特点和不同病期染色体核型演变的特点及其意义。方法采用骨髓直接法和短期培养法制备染色体,应用R显带技术对211例CML患者进行染色体核型分析。结果Ph+患者占91.5%,Ph-患者占5.7%。在Ph+患者中,93.8%为典型Ph染色体阳性,6.2%为变异型Ph染色体阳性。19.7%的患者发生染色体核型演变。急变期、加速期和慢性期染色体核型演变的发生率分别为66.7%、50%、2.1%。结论染色体核型分析对慢粒的诊断及预后具有重要的意义,CML病程中定期 ...

Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Zhongguo shiyan zhenduanxue, 2020 目的研究不孕不育患者染色体核型特点并分析其临床特征。方法以在本院2013年8月-2018年8月就诊的242例不孕不育患者为研究对象,采集患者外周血进行淋巴细胞培养,制备染色体标本,进行染色体核型分析。结果 242例不孕不育患者中染色体核型异常有54例,其中染色体结构异常8例,占总不孕不育人数的3.31%;数量异常1例,占总不孕不育人数的0.41%;多态性核型45例,占总不孕不育人数的18.60%。结论染色体数目或结构异常是导致不孕不育的重要原因,因此染色体核型测定能深入了解不孕不育原因 ...

Design, synthesis and preliminary bio-evaluation of progestrone receptor targeting probes for breast cancer imaging with PET [PDF]
, 2016 乳腺癌是严重威胁女性健康的疾病，它的早期诊断能够有效的降低病人的死亡率。孕激素受体属于核受体超家族，有PRA和PRB两种亚型，在调节和控制卵巢，子宫和乳腺的功能方面有重要作用。研究表明，在雌激素受体阳性（ER+）的乳腺癌病人中，PR的表达与否不会对病人接受他莫西芬治疗的疗效产生影响。但是在雌激素受体表达阴性（ER-）的乳腺癌病人中，病人接受他莫西芬治疗的疗效依赖于PR的表达。因此，监测PR的表达对乳腺癌的早期诊断和ER-/PR+病人的治疗都是很重要的。PET的灵敏度高，空间分辨率好，安全性也较好 ...

Decoding Paradoxes in Digital Government: Strategies for the Pursuit of Public Value
Public Administration, Volume 104, Issue 1, Page 188-201, March 2026.ABSTRACT This study aims to analyze the complexities of paradoxes in digital government. Through a focused analysis of 34 selected articles, adhering to PRISMA guidelines, it codifies seven paradoxes, categorized into “internal governance paradoxes” and “external engagement paradoxes.” These paradoxes arise from conflicting values among governments ...

, 2018 鱼类的染色体核型分析是鱼类遗传学研究的基础,作为我国重要养殖品种的双斑东方鲀(Takifugu bimaculatus)尚未发现有染色体核型的相关报道.采用体内注射植物血球凝集素(PHA)及秋水仙素法制备了双斑东方鲀头肾组织染色体标本并分析其核型.结果表明,双斑东方鲀二倍体染色体数为2n=44,其染色体臂数为NF=62,核型公式为12m+6sm+26t.通过比较分析推测2n=44应该是东方鲀属的染色体基础核型,而其染色体核型的高度保守可能是东方鲀属鱼类易于发生种间杂交的主要原因之一 ...

People and Nature, Volume 8, Issue 2, Page 270-282, February 2026.Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and
