The Microstructure Evolution and Mechanical Properties of (FeCoCrNi)100‐x(AlCu)x High‐Entropy Alloys

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT This study systematically investigates the effects of AlCu addition on the microstructural evolution and mechanical properties of (FeCoCrNi)100‐x(AlCu)x (x = 0, 5, 10, 15, 20; at%) high‐entropy alloys (HEAs). The results reveal that the microstructure evolves from coarse equiaxed to refined equiaxed, dendritic, and ultimately dual‐phase ...

移植肾排异背景下血清多反应性IgG对凋亡细胞反应性升高并激活补体途径

open access: yesZhongguo shiyan zhenduanxue, 2017
抗体介导的排异反应(Antibody mediated rejection,AMR)是肾移植后导致移植物失功的主要原因之一。而AMR的核心特征是受者循环中出现针对移植物的抗体,此类抗体包括移植前预存于体内的抗体以及移植后新生抗体。当抗体为特异性识别供者所表达的HLA抗原时则被称为供者特异性抗体(Donor specific antibodies,DSA),而当抗体识别的是自身表达的抗原时则被称为自身抗体 ...

Adaptive Crystallization of NiFe‐MIL‐55 Nanorods: Atomically Precise Shape Control and Dual‐Function Electrocatalytic Performance

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT NiFe‐based MIL‐55 metal‐organic frameworks (MOFs) face challenges in achieving atomically precise composition and reliable methods for uniform growth. This study addresses these challenges by applying a slow evaporation crystallization technique to crude colloidal MIL‐55 products from hydrothermal synthesis, resulting in highly uniform ...

Amphiphilic Block Copolymer‐Functionalized VO2 Nanocomposites for Smart Waterborne Polyurethane Coatings

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Aqueous vanadium dioxide (VO2)‐based smart thermal insulation coatings represent a viable strategy to decrease building energy consumption and advance sustainable development goals. However, the inherent instability and limited compatibility with polymer matrices of VO2 hinder its widespread application.

Ⅰ型自身免疫性肝炎患者抗Ro52抗体的检测及临床意义

open access: yesZhongguo shiyan zhenduanxue, 2014
目的探讨I型自身免疫性肝炎患者抗Ro52抗体的临床意义。方法采用免疫印记法检测54例I型自身免疫性肝炎(autoimmune hepatitis,AIH)患者血清中的抗Ro52抗体,根据检测结果分为抗Ro52抗体阳性组与阴性组,并对两组检测结果及临床资料进行回顾性分析。结果 54例I型AIH患者中,抗Ro52抗体阳性20例(37%)。抗Ro52抗体阳性组与阴性组Ⅰ型AIH患者的抗核抗体(ANA分布主要见于滴度1∶3201∶1000)。20例抗Ro52抗体阳性患者中,5例(25%)抗可溶性肝原(抗SLA ...

Reconsider mumps infection [PDF]

open access: yes, 2012
ムンプスの感染予防対策を目的として、医薬系学生2,258名を対象に、2004年から2011年までの8年間、擢患歴と予防接種歴のアンケート調査を行い、ムンプス抗体価を測定した。その結果、ムンプスの平均抗体陽性率は76.1% であった。2004年の調査開始時からの傾向では、近年は抗体陰性者は減少傾向にあるものの、抗体価が弱陽性を示す学生が、20%前後と増加傾向にあり、全体としての抗体陽性者が減少傾向にあることが判明した。特に男性にその傾向が強く認められた。入学時アンケート調査によれば ...

抗Sm抗体对狼疮性肾炎的临床意义 附视频

open access: yesZhongguo shiyan zhenduanxue, 1997
将130例狼疮性肾炎(LN)分为两组,组A抗Sm及抗ds-DNA抗体均阳性,组B仅抗ds-DNA抗体阳性。通过对两组年龄、性别、病程、临床症状、血液学及免疫学预后的比较,分析抗Sm抗体在LN的临床意义,结果发现:①抗Sm抗体与疾病活跃程度相关,可作为判断病情、监测治疗的血清学指标;②抗Sm抗体阳性常伴内脏病变发生率高以及皮肤损害严重,易脱发;③抗Sm抗体为标记性抗体 ...
