Rare Metals, Volume 43, Issue 8, Page 3702-3712, August 2024.Graphical abstract AbstractThe highly reversible insertion/extraction of large‐radius K+ into electrode materials remains a tough goal, especially for conversion‐type materials. Herein, we design a current collector‐integrated electrode (N–CoSe/CoSe2–C@Cu) as an advanced anode for potassium‐ion battery (PIBs).

Application of Gas-Contrasted and Window Technic in Diagnosing Gastro-Colon Lesion with CT [PDF]
, 2008 目的探讨空气造影低剂量CT扫描及低窗位图像诊断肠道病变的应用价值。方法126例疑有胃或结肠病患者随机分为2组,一组(69例)采用传统的水造影或无造影常规剂量CT扫描及常规窗位诊断,另一组(57例)采用空气造影低剂量CT扫描及低窗位图像诊断,以内窥镜检查为诊断标准,由资深医生采用单盲法评价诊断,比较2组图像的诊断自信度及正确率。结果医生对空气造影低剂量CT扫描及低窗位图像的诊断自信度和正确率明显优于传统的水造影或无造影常规剂量CT扫描常规窗位图像 ...

The role of EGFR/ERK signaling for the self-renewal of germinative cells of Echinococcus multilocularis and its molecular mechanism [PDF]
, 2016 多房棘球绦虫（Echinococcusmultilocularis，Em）中绦期幼虫(泡球蚴)在人体内以类似肿瘤的方式进行不断的增殖发育，引发严重的人兽共患泡球蚴病（Alveolarechinococcosis，AE）。泡球蚴不断增殖发育的基础是其生发细胞的自我更新和分化能力，这一特性类似于干细胞。表皮生长因子受体（EGFR）介导的EGFR/ERK信号通路是调控各种干细胞自我更新的主要通路之一，在进化上具有高度的保守性。 本文利用RealtimePCR、WesternBlot、免疫组化荧光和EdU ...

Function and mechanism of Repulsive Guidance Molecule RGMb/Dragon during Colorectal Cancer progression [PDF]
, 2016 结直肠癌是我国甚至全球范围内最常见的肿瘤之一，也是肿瘤相关死亡的主要原因之一。及时而有效的诊断是降低结直肠癌死亡率的重要措施。除了临床上常规的诊断及治疗方法外，人们也在不断致力于新型肿瘤标志物的研究，以进一步明确结直肠癌发生发展的机制。排斥导向分子(RGM)家族成员RGMb，又名Dragon，作为骨形态发生蛋白(Bonemorphogeneticprotein，BMP)通路的辅助受体，不但承载着胚胎发生、神经修复和肾脏正常生理功能，还与各种上皮来源肿瘤的发生发展密切相关。然而，RGMb ...

3D Change Detection of Tumor in Shape and Texture Based on Liver CT [PDF]
, 2016 肝癌是我国最为常见的一种恶性肿瘤，严重威胁到了人类生命健康，如何预防和治疗肝癌成为人类医疗领域的极大挑战。通过CT序列可以得到丰富的肿瘤信息，将这些信息以各种直观的形式展现出来可以帮助临床医生更好的分析病情。本文基于CT图片序列，着重从三维形态和三维纹理两个方面进行肿瘤变化分析，从而进一步推断肿瘤疗效： 首先，在进行肿瘤变化分析之前，需要从CT序列中分割出肿瘤区域并进行三维重建，排除其他组织对后续分析的影响。在分割阶段，为了能够得到理想的分割结果，为后续疗效分析铺垫基础，采用了先预处理 ...
