MRI-T2*检测β-重型地中海贫血心、肝、胰铁沉积的临床价值
Zhongshan Daxue xuebao. Yixue kexue ban, 2020 目的MRI-T2*定量评价β-重型地中海贫血（β-TM）患者心肌、肝脏、胰腺铁沉积程度，探讨心肌铁沉积与肝脏、胰腺铁沉积的关系。方法回顾性分析2014年5月至2016年1月期间在我院行心脏、肝脏、胰腺MRI-T2*检查的109例β-TM患者的临床、实验室和MRI资料，采用Spearman相关性分析探讨心肌T2*值与肝脏、胰腺T2*值之间关系。将心肌、肝脏铁沉积的患者纳入A组（n=32），仅肝脏铁沉积、而心肌铁含量正常的患者纳入B组（n=69），将心肌、胰腺铁沉积的患者纳入C组（n=34），仅胰腺铁沉积 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

SE PUBLICAR É PRECISO, AVALIAR TAMBÉM É! [PDF]
Revista de Administração de Empresas, 2018 O tema “revisão de artigos” é relevante e faz parte do cotidiano de todo pesquisador. Entretanto, a minha experiência como editor e revisor em periódicos brasileiros e internacionais torna evidente que o comprometimento dos pesquisadores na função de revisores, em geral, é muito menor do que quando estão na posição de autores.

Novos Estudos - CEBRAP, 2021 O objetivo deste artigo é argumentar que situações de privação material são inerentemente coercitivas. Para isso, avaliam-se teorias da justiça para as quais a pobreza não representaria uma forma de intervenção coercitiva em contextos de livre-mercado. Argumenta-se aqui que a pobreza precisa ser concebida como uma posição social subordinada e, portanto,

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT The commercialization of lithium‐sulfur batteries (LSBs) faces dual challenges of sluggish sulfur redox kinetics and lithium polysulfides (LiPSs) shuttling. Herein, we demonstrate a synergistic strategy combining multidimensional structural confinement with d‐band center modulation to simultaneously suppress LiPSs diffusion and catalyze ...
