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

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).

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 ...

One-step Deposition of Melanin-like Polymer on individual Escherichia Coli cells Exhibiting an Special Effect of UV- and Lysozyme - Resistance [PDF]
, 2015 尽管紫外线只占到达地球表面的阳光辐射能量中的一小部分，但若长期暴露于这部分紫外辐射之下，几乎所有的有机生命体都将直接或间接地因受到光损伤而导致其遗传物质核酸遭受破坏，进而造成机体死亡。为了应对太阳光中的这部分紫外辐射，某些微生物已经进化出了许多生物化学或生物行为光保护机制。黑色素，由于其具有很强光吸收和良好能量转换性质，可以将有害辐射能高效地转换为热能进而耗散至周围环境中，黑色素一直被认为是所有已知的光保护机制中最高效的。因此，结合黑色素的性质，人们可以使用其来提高某些生物工程菌的抗紫外性能 ...

Zhongguo shiyan zhenduanxue, 2016 纵隔疾病病因繁多,结构复杂,使纵隔疾病的诊断成为临床难点。CT、MRI、PET-CT等影像学检查虽对纵隔病变诊断敏感性较高,但却缺乏定性诊断依据。过去纵隔镜一直被作为纵隔疾病诊断的主要手段,但因其创伤大、风险高,诊治费用昂贵等缺点,临床应用受到限制。超声引导电子支气管镜（endobronchial ultrasound,EBUS）,通过支气管镜前端搭载的电子凸阵扫描超声探头进行扫描 ...
