As I compose this editorial, many histotechnology colleagues, NSH members, reviewers and authors are dealing with the impact of the SARS-CoV – 2 pandemic on their work and private lives. Hopefully, this highly infectious disease has waned by the time this issue is printed and never seen again. A huge thank goes to Tony Henwood for his ‘Disinfection in Histopathology’ found in this issue. This article is one of the fastest publications in JOH from submission to the final open-access paper. Due to the seriousness of this coronavirus, many journals and publishers, including our publisher Taylor and Francis, granted free/open access to CoV-2 publications. This was done to rapidly disseminate information on guidelines for handling CoV-2 infected specimens [1,2] provide pathology reports and basic ongoing research [3] to combat the disease. Tony Henwood’s timely and now well-received article will inform and help histotechnicians and other histopathology staff maintain a safe working environment during and beyond this pandemic. This issue has a very international feel with articles from authors in Australia, Turkey, Brazil, Poland and Romania. Oguz and his group presented an interesting study on a fish species from Lake Van in Turkey, one of the largest salt lakes in the world. The fish, infected with a gill parasite, have economic importance as a food source in that region and the study was done using routine staining and an immunohistochemistry to assess this parasite. One novel study used of natural wood product for staining connective tissues. Pereria and colleagues found a pigment extracted from eucalyptus wood developed a stain for collagen fibers and compared their results to hematoxylin and eosin and Masson’s trichrome methods. We must always remember that themost important, common dye used in histopathology laboratories, hematoxylin, came from a wood extract. Laboratories worldwide continue to explore natural plant products containing pigments and develop special stains for different tissue elements as compared to what is routinely used in the USA and other countries. Another novel way of staining mitochondria other than using an immunochemistry assaynot always available to some laboratories was presented by Ruxanda and workers to detect apoptotic hepatocytes. Mitochondria, being extremely small and difficult to see with a light microscope, were visible microscopically after using this unique special stainingmethod. It would be a rare issue without a paper on an immunohistochemical assay (IHC) to aid in clinical diagnosis of some disease. The article by the Woźniak group from Poland studied the role of osteopontin on the pathogenesis of various renal cell carcinomas with microarrays prepared from archived paraffin tissue blocks, Western blot analysis and IHC.Hopefully, this groupwill continue their research on this topic with a follow up paper for JOH. I end with a sad note on the passing of Cheryl Crowder, a JOH Editorial Board member, a skilled, knowledgeable reviewer and author of JOH publications. Cheryl was a mentor and teacher who freely shared a vast histology background in the veterinary field especially on marine and fresh water species, and a pioneer of microwave histotechniques. Her service to JOH and our profession will be missed, but most of all the personal loss of a good friend.

作为组织病理学专业人士，增加您的学习经验：处理 SARS-Cov-2 大流行和本期出版物

在我撰写这篇社论时，许多组织技术同事、NSH 成员、审稿人和作者正在处理 SARS-CoV-2 大流行对其工作和私人生活的影响。希望这种高度传染性的疾病在本期出版时已经消退，再也不会出现。非常感谢 Tony Henwood 在本期中发现的“组织病理学消毒”。这篇文章是 JOH 从提交到最终开放获取论文最快的出版物之一。由于这种冠状病毒的严重性，包括我们的出版商 Taylor 和 Francis 在内的许多期刊和出版商都授予了对 CoV-2 出版物的免费/开放访问权。这样做是为了快速传播有关处理 CoV-2 感染标本的指南的信息 [1,2] 提供病理报告和正在进行的基础研究 [3] 以对抗该疾病。托尼·亨伍德 (Tony Henwood) 及时且现在广受欢迎的文章将告知并帮助组织技术人员和其他组织病理学工作人员在大流行期间和之后保持安全的工作环境。本期刊载了来自澳大利亚、土耳其、巴西、波兰和罗马尼亚的作者的文章，具有非常国际化的感觉。Oguz 和他的团队对来自土耳其凡湖（世界上最大的盐湖之一）的一种鱼类进行了一项有趣的研究。感染了鳃寄生虫的鱼作为该地区的食物来源具有重要的经济意义，这项研究是使用常规染色和免疫组织化学来评估这种寄生虫的。一项使用天然木制品染色结缔组织的新研究。Pereria 及其同事发现，一种从桉木中提取的色素可以对胶原纤维进行染色，并将他们的结果与苏木精和伊红以及马森三色法进行比较。我们必须永远记住，组织病理学实验室使用的最重要、最常见的染料苏木精来自木材提取物。与美国和其他国家/地区常规使用的相比，世界各地的实验室继续探索含有色素的天然植物产品，并为不同的组织元素开发特殊的染色剂。Ruxanda 和工作人员提出了另一种新的线粒体染色方法，而不是使用某些实验室并不总是可用的免疫化学测定法来检测凋亡的肝细胞。线粒体非常小，用光学显微镜很难看到，使用这种独特的特殊染色方法后，在显微镜下可见。如果没有关于免疫组织化学分析 (IHC) 的论文来帮助某些疾病的临床诊断，这将是一个罕见的问题。来自波兰的 Woźniak 小组的文章通过存档石蜡组织块制备的微阵列、蛋白质印迹分析和 IHC 研究了骨桥蛋白在各种肾细胞癌发病机制中的作用。 JOH 的论文。最后，我对谢丽尔·克劳德 (Cheryl Crowder) 的逝世表示悲痛，JOH 编辑委员会成员、技术娴熟、知识渊博的评论家和 JOH 出版物的作者。Cheryl 是一位导师和老师，她自由地分享了兽医领域的广泛组织学背景，尤其是海洋和淡水物种，和微波组织技术的先驱。她对 JOH 的服务和我们的职业将会被怀念，但最重要的是失去一位好朋友。
