现代微生物学是面向基础医学专业硕士研究生开设的一门专业基础课程,旨在培养学生的基本科研素养和科研创造力,而传统的讲授型授课方式已无法满足新时代医学研究生教育要求。因此,本文通过专题教学与seminar教学模式(“讨论课”教学模式)相结合,设置六大专题板块辅以学生seminar汇报讨论,应用于现代微生物学研究生课程教学,探讨该教学实践的应用效果,全面提升医学研究生的知识理论水平,培养具有创新思维和具备基本科研素质的高层次医学人才,也为医学类专业其他研究生课程的教学改革提供有益参考。 相似文献

生物化学课程作为专业基础课程,在生物、食品、医学、发酵等专业中广泛开设,承担着培养人才的重任。随着大思政思想渗透到所有学科和专业,生物化学课程思政建设的成败直接关系到为党育人、为国育才的成效。构建生物化学课程思政,并有机融合课程教学,是实现全方位育人的关键。基于新工科背景,本文从生物化学概况、生物化学课程思政建设的必要性、生物化学课程思政建设方案、实施策略及成效等方面对该课程近年的课程思政实践与探索进行总结,以期为相关高等院校生物类专业课程思政建设提供参考。 相似文献

医学高职高专院校以培养适应医疗卫生服务第一线,具有良好职业素质、过硬职业技能、熟练岗位能力的高等技术应用性人才为宗旨,因此与普通本科院校相比,具有自身独特的教学理念与教学模式.生物化学是一门理论性较强的综合性学科,涉及生物学、遗传学、分子生物学、医学以及化学等多个学科的内容.在医药卫生院校,生物化学是多个专业的基础课程,如何在生物化学的教学中体现职业特色,对高职高专院校实现其培养应用型人才的办学宗旨非常重要.高职院校生物化学教学必须准确理解高职教育质量观、人才观, 遵循高职教育规律, 突出高职教育的职业特色,才能保证自身优势,占领医学高等教育的一方市场,实现自身的长远发展.本文从生物化学的理论教学、实践教学、教学方法以及教师素质四个方面探讨医学高职高专生物化学教学的职业特色体现,现介绍如下. 相似文献

聚糖在生理、病理中作用机制的阐释使聚糖与医学的相关性得到重视,聚糖结构的变化常与疾病直接相关。生物化学作为生物相关专业的重要基础课程,其教学内容也应该引入新的科研成果,与时俱进。目前各个版本的生物化学课本并未涉及“聚糖与医学”相关知识,本文对“聚糖与医学”相关内容在生物化学教学中的引入进行了探讨,并对肿瘤等疾病中的异常聚糖以及聚糖在疾病治疗和诊断中的应用等引入内容进行了具体阐述。“聚糖与医学”相关内容的引入符合“基础与临床”相结合的教学理念,有利于增加学生对科研前沿的了解,提升学生的科研素养和核心竞争力。 相似文献

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 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

The young pistils in the melanthioid tribes, Hewardieae, Petrosavieae and Tricyrteae, are uniformly tricarpellate and syncarpous. They lack raphide idioblasts. All are multiovulate, with bitegmic ovules. The Petrosavieae are marked by the presence of septal glands and incomplete syncarpy. Tepals and stamens adhere to the ovary in the Hewardieae and the Petrosavieae but not in the Tricyrteae. Two vascular bundles occur in the stamens of the Hewartlieae and Tricyrtis latifolia. Ventral bundles in the upper part of the ovary of the Hewardieae are continuous with compound septal bundles and placental bundles in the lower part. Putative ventral bundles occur in the alternate position in the Tricyrteae and putative placental bundles in the opposite. position in the Petrosavieae. The dichtomously branched stigma in each carpel of the Tricyrteae is supplied by a bifurcated dorsal bundle. 相似文献
