Veterinary Dermatology, Volume 34, Issue 6, Page 586-596, December 2023., 2023 Background – In clinical practice, the diagnosis of otitis externa (OE) normally is based on otoscopic examination and cytological findings, followed by empirical treatment with topic drugs. Biofilm‐producing bacteria are frequently present in OE, even if its presence is often underdiagnosed. Hypothesis/Objectives – The primary aim of this study was to

Zhejiang Daxue xuebao. Lixue ban, 2016 利用静电纺丝和交联技术，制备了植酸(PA)修饰聚乙烯醇(PVA)纤维膜负载钯催化剂.利用扫描电子显微镜(SEM)表征了纤维膜的微观结构；采用扫描电子显微镜-能谱仪(SEM-EDS)分析了 Pd催化中心在纤维膜上的分布；采用红外光谱研究了纤维膜的化学结构.Mizoroki-Heck偶联反应结果显示，植酸的引入可以提高纤维膜催化剂的催化活性；该催化剂对不同结构的碘代芳烃和丙烯酸酯都表现出良好的催化性能；而且该催化剂至少可以重复使用4次其活性基本保持不变.

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).

Gaoya dianqi, 2022 为了深入地研究复合绝缘子的酥朽断裂，获得其与脆断的异同，文中对现场酥断故障复合绝缘子进行了外观形貌检查、扫描电镜分析、傅里叶光谱分析以及X射线扫描分析，并且将结果与脆断绝缘子进行了相应地对比分析。分析表明：酥朽绝缘子断口颜色不再正常，芯棒变软劣化，脆断端口颜色正常；与脆断相比，酥朽样品的电镜结果出现了树脂的气泡现象，纤维丝裸露更严重；元素分析表明，两者都受到了硝酸入侵，都出现了芯棒的水解，但酥朽时更严重。基于实验结果，对两者的断裂机理进行了总结分析，得出放电与酸是造成这类故障的共同因素。

Veterinary Dermatology, Volume 35, Issue 3, Page 325-336, June 2024.Background – Norway spruce (Picea abies) resin‐based products are used in human medicine. A resin‐based otic rinse also could be useful in supportive care of canine otitis externa (COE), yet information on its antimicrobial effect against canine pathogens or ototoxicity is lacking.

诊断剂量超声联合超声造影剂照射对体外培养成纤维细胞细胞膜影响的实验研究
Zhongguo shiyan zhenduanxue, 2007 目的观察超声联合超声造影剂照射对体外培养成纤维细胞细胞膜的影响。方法将6孔板培养成纤维细胞分为对照组、单纯超声照射组、造影剂组、超声联合造影剂组,超声条件为探头频率2.5 MHz,二次谐波模式,机械指数1.6,聚焦3 cm,深度5 cm,照射时间60 s;照射后立即将细胞送电镜室进行扫描电镜观察。其中超声联合造影剂组分为两组,一组于照射后立即进行扫描电镜观察,另一组继续培养24h后再进行扫描电镜观察。结果单纯超声辐射组及造影剂组成纤维细胞形态以及细胞膜的形态结构与对照组相比无显著变化 ...
