关键词： 生物化学   课堂教学   实战经验   创造性思维   教学改革  

摘要： 现阶段高校本科《生物化学》课程的教学目标注重应用型人才的培养,着重于训练学生的创造性思维和创新能力。为了更好地实现这个目标,《生物化学》课程的教学内容有必要进行合理的调整,并选择与之相符的教学资源;再通过教学方法相应的改进,把注意力更多地放在学生上,以激发学生学习生物化学的兴趣,培养学生运用生物化学理论知识来解决实际问题的意识和能力。文章基于自身的本科《生物化学》课堂教学经历,主要从教学内容和教学方法两个方面对课程进行了总结和分析,希望为《生物化学》课程教学改革提供有价值的实战参考经验。

关键词： 医学生物化学   绪论   教学方法  

摘要： 生物化学在医学课程中占有十分重要的地位,但因其代谢途径多,反应复杂,晦涩难懂,学生的畏难情绪普遍严重。绪论课在生物化学整个课程教学中发挥着提纲挈领的作用,其教学的成功与否直接影响能否消除学生的畏难情绪,激发学生学习兴趣,能否成功建立课程的整体框架。本文围绕医学生物化学绪论课教学,分别从重视生化绪论教学、讲清生物化学概念、讲好科学家故事、巧设伏笔激发兴趣、精用病例联系临床及学习方法几个方面浅谈笔者多年生物化学绪论教学实践的思考与体会,以期与同行交流分享,为提高医学生物化学绪论教学质量提供参考。

关键词： 《食品生物化学》   OBE理念   改革与实践  

摘要： 《食品生物化学》是食品类专业的一门核心必修课程,具有很强的理论性与实践性。在传统教育模式下,学生无法将理论知识充分运用到实践中,导致教学效果不尽如人意。OBE是一种以成果为导向的教育理念,该文通过探索《食品生物化学》课程教学模式,改进现有教学方式,激发学生学习热情,实现学生自主学习,以期达到良好的教学效果,并满足社会对人才的需求。

关键词： Dehydration   Equine   Muscle  

摘要： The purpose of this study was to establish the reference ranges of serum biochemistry parameters of Brazilian Sport Horses undergoing training in a tropical climate. Eighty-nine Brazilian Sport Horses (4 to 11 years; castrated males and females) that were training and competing for equestrian disciplines (showjumping, dressage and eventing) in a tropical climate were selected for this study. All horses had, at least, 48 h of rest before the vacuum venipuncture of the external jugular vein . Approximately, 8mL of venous blood were collected in tubes without anticoagulant to perform the serum biochemical analysis. The parameters analyzed were aspartate transaminase (AST), creatine kinase (CK), urea, creatinine, alanine transaminase (ALT), gamma-glutamyl transferase (GGT), albumin and calcium by an automatic spectrophotometer . The reported values were applied to the probability density function formula and were described as a normal distribution. The Tukey Test was used to determine the minimum and maximum limits using the 5 and 95% percentiles. Most of the parameters were within the reference interval indicated, except for CK and albumin, in which 93.25% and 94.38% of the horses, respectively, presented the results considered normal (Table 1). This alteration can be explained by muscular lesion due to excessive training and to dehydration in reason of the high temperatures and humidity. This information was confirmed by clinical examination. The study was done by the end of the equestrian season, which may explain these results. It is known that the training protocol the horses are imposed to may lead to overtraining. The loss of performance and the observance of different clinical signs such as reluctance to move, lameness and increased skin-pinch test may be important to help the diagnosis. In conclusion, the tropical climate influenced the results of athletic horses, altering CK and albumin. It is important to analyze data respecting the geographical location, cli

关键词： 翻转课堂   高职生物化学教育   实施应用  

摘要： 作为高职院校教学体系的核心组成部分,生物化学教学课堂一般难以遵循传统的教学方式,教学观念和教学方法较为落后、单一。它无法激发学生学习的热情和热情,并且对教学成果产生一定的负面影响。本文为深化生物化学教学过程提供了最新思路,教育学生在职业水平上使用生物化学教学。本文分析生化课堂存在的问题并提出可逆课堂教学模式的可行性,旨在为提高生物化学教学质量提供可行性的建议。

关键词： 生物化学   课程思政   探索实践   困惑   解决路径  

摘要： 近两年来,在生物化学教学中进行思政教育的实践表明,把思政元素融入生物化学教学可以在学生中产生思想共鸣,但也存在很多问题。对此,课程组提出如下解决路经:首先要写好教案,做好课程思政的整体设计;其次,要对思政元素进行系统化整合,围绕专题把思政内容传达给学生以加深印象;最后,还要做好思政教育的教学评价,采取灵活多样的评价方式,内化思政教育成果。

摘要： The increasing demand for and the necessity of using sustainable resources require the further development of alternative technologies. The project "CrossCat - Symbiosis of bio- & chemo-catalysts for the sustainable conversion of hemicelluloses" deals with the utilization of the hemicellulose fraction, especially xylan. In an example process for combining of biological and chemical catalysts in a one-pot process, xylan shall first be hydrolyzed to xylose and then hydrogenated to xylitol. To make this possible, suitable immobilization of the xylanases is required. For this purpose, the xylanases were immobilized covalently using glutaraldehyde (GDA) on various carrier materials with and without surface functionalization and activation. Immobilization on uncoated stainless steel hollow spheres with simultaneous covalent binding to the surface and cross-linking of the enzymes was most suitable for later use. The produced immobilizates showed an increased long-term stability (57 % residual activity after 24 h) compared to free enzymes (8 %) and could be used for several days (4?6 d) for the hydrolysis of xylan to xylose.
