以“新冠”病毒肺炎疫情为案例的问题导向式微生物学课程思政教学设计

在微生物学课程中开展思政教学有助于提升相关专业学生的思想道德修养和综合素质,是当前高校教育"立德树人"根本任务的具体要求,也是思政教育"全过程、常态化"的重要体现。案例教学法是微生物学课程思政的一种重要教学方法,主要以微生物学科发展中的一些著名学者及其事迹为案例,引导学生认识和理解这些案例的思想内涵,以提升自身思想道德水平。该教学方法在实践中获得了较为理想的教学效果,但也存在着设计不够充分、时效性不足等问题。针对这些问题,本文提出了以新型冠状病毒肺炎(COVID-19,简称"新冠"病毒肺炎)疫情为案例的问题导向式微生物学课程思政教学设计方案。该设计基于当前"新冠"病毒肺炎疫情中涌现出的诸多先进人物和事迹,以及暴露出的一些不良现象和问题,通过将这些案例与微生物学专业知识,以及微生物学科发展历史上的经典人物事迹进行有机整合和提炼,开展问题导向式教学。这些案例都是学生亲身经历过的重大事件,因此能有效地提升学生的参与感,引发学生的共鸣。使用这些案例是对微生物学课程思政经典教学案例的有益补充,能更好地引导学生在学习相关专业知识的同时,主动思考各案例所蕴含的思想道德意义并将之内化为自己的价值信念,帮助他们塑造正确的"三观",最终实现微生物学课程思政"寓思想教育于科学知识学习"的教学目标。     

“环境工程微生物学”课程思政实践举措

科学史视角下的“基因工程”课程思政探索与实践

课程思政是新时期高校思想政治教育的重要途径之一。科学史记载了科学知识从产生到持续发展的过程,蕴含着丰富的育人价值,能够为专业课的课程思政教学提供新的视角和思路。本文从科学史丰富的育人价值中选择科学精神、科学思维、科学兴趣和科学伦理4个方面的素材;依托"基因工程"课程内容,对有关诺贝尔奖的科学史进行梳理;然后,以4个方面的素材为育人载体,深挖其中蕴含的思政元素,通过实施课程思政教学,帮助学生达成课程思政目标;最后,综合运用问卷和深度访谈相结合的方式评价教学效果。借此引领学生树立正确的价值观,提高思想政治水平,以期为生物学专业的课程思政体系建设提供参考。

深化课程思政建设,落实立德树人根本任务是新时代教育改革和人才培养的重要要求。微生物学实验课是生物工程、制药工程和食品科学与工程等多个专业的专业基础课和核心实践课。为充分发挥微生物学实验课育人功能,文中参考《高等学校课程思政建设指导纲要》,积极挖掘课程蕴含的思政元素,通过教学内容改革、教学方法创新、教师课程思政建设能力提升等3个方面进行微生物学实验课程思政改革探索,力求将价值塑造、知识传授、能力培养融为一体,培养具有坚定理想信念的高素质专业人才。     

Recent advances in the study of Kaposi's sarcoma-associated herpesvirus replication and pathogenesis

It has now been over twenty years since a novel herpesviral genome was identified in Kaposi's sarcoma biopsies. Since then, the cumulative research effort by molecular biologists, virologists, clinicians, and epidemiologists alike has led to the extensive characterization of this tumor virus, Kaposi's sarcoma-associated herpesvirus(KSHV; also known as human herpesvirus 8(HHV-8)), and its associated diseases. Here we review the current knowledge of KSHV biology and pathogenesis, with a particular emphasis on new and exciting advances in the field of epigenetics. We also discuss the development and practicality of various cell culture and animal model systems to study KSHV replication and pathogenesis.     

A Unique Protease Cleavage Site Predicted in the Spike Protein of the Novel Pneumonia Coronavirus (2019-nCoV) Potentially Related to Viral Transmissibility

正Dear Editor,In December 2019, a novel human coronavirus caused an epidemic of severe pneumonia(Coronavirus Disease 2019,COVID-19) in Wuhan, Hubei, China(Wu et al. 2020; Zhu et al. 2020). So far, this virus has spread to all areas of China and even to other countries. The epidemic has caused 67,102 confirmed infections with 1526 fatal cases     

Curcuminoids as inhibitors of thioredoxin reductase: A receptor based pharmacophore study with distance mapping of the active site

Curcumin is the yellow pigment of turmeric that interacts irreversibly forming an adduct with thioredoxin reductase (TrxR), an enzyme responsible for redox control of cell and defence against oxidative stress. Docking at both the active sites of TrxR was performed to compare the potency of three naturally occurring curcuminoids, namely curcumin, demethoxy curcumin and bis-demethoxy curcumin. Results show that active sites of TrxR occur at the junction of E and F chains. Volume and area of both cavities is predicted. It has been concluded by distance mapping of the most active conformations that Se atom of catalytic residue SeCYS498, is at a distance of 3.56 from C13 of demethoxy curcumin at the E chain active site, whereas C13 carbon atom forms adduct with Se atom of SeCys 498. We report that at least one methoxy group in curcuminoids is necessary for interation with catalytic residues of thioredoxin. Pharmacophore of both active sites of the TrxR receptor for curcumin and demethoxy curcumin molecules has been drawn and proposed for design and synthesis of most probable potent antiproliferative synthetic drugs.     

The structure, reproduction and taxonomy of Vidalia and Osmundaria (Rhodophyta, Rhodomelaceae)

Comprises species occurring mostly in subtidal habitats in tropical, subtropical and warm-temperate areas of the world. An analysis of the type species, V. spiralis (Sonder) Lamouroux ex J. Agardh, a species from Australia, establishes basic characters for distinguishing species in the genus. These characters are (1) branching patterns of thalli, (2) flat blades that may be spiralled on their axis, (3) width of the blade, (4) primary or secondary derivation of sterile and fertile branchlets and (5) position of sterile and fertile branchlets on the thalli. Application of the latter two characters provides an important basic method for separation of species into three major groups. Osmundaria , a genus known only in southern Australia, was studied in relation to Vidalia , and its separation from the Vidalia assemblage is not accepted. Species of Vidalia therefore are transferred to the older genus name, Osmundaria. Two new species, Osmundaria papenfussii and Osmundaria oliveae are described from Natal. Confusion in the usage of the epithet, Vidalia fimbriala Brown ex Turner has been clarified, and Vidalia gregaria Falkenberg, described as an epiphyte on Osmundaria pro/ifera Lamouroux, is revealed to be young branches of the host, Osmundaria prolifera.     

New or rare chromosome counts in Artemisia L. (Asteraceae, Anthemideae) and related genera from Kazakhstan

Fifteen chromosome counts of six Artemisia taxa and one species of each of the genera Brachanthemum, Hippolytia, Kaschgaria, Lepidolopsis and Turaniphytum are reported from Kazakhstan. Three of them are new reports, two are not consistent with previous counts and the remainder are confirmations of very scarce (one to four) earlier records. All the populations studied have the same basic chromosome number, x = 9, with ploidy levels ranging from 2x to 6x. Some correlations between ploidy level, morphological characters and distribution are noted.
