基于科研能力培养的地方高校植物生理学实验教学改革

目前地方高校植物生理学实验课教学主要是基础验证性实验,同时课堂中"注入式"教学方法不利于激发学生学习热情和培养学生动手与科研思维能力。针对这些问题,对植物生理实验课教学进行了改革,将单一的小实验进行有机融合,使之成为综合性实验,从而提高学生的知识系统性、实验主动性以及科研创新能力。让学生参与实验准备环节以提高学生的动手能力,在课堂中运用启发式教学以提高学生学习兴趣和教学效果。此外,将实验报告改革为研究论文,从而提高学生的科研论文写作能力。     

加强病理学教学与临床学科联系的探索

病理学是临床医学的基础学科之一,与临床各科关系密切.在教学过程中加强病理学内容与临床相关学科的联系,对培养学生的临床思维能力、思考能力有着重要意义.笔者结合本学科特点,通过加强对学生学习病理学知识的同时,通过各种形式把病理学知识与临床相关学科有机结合起来,从而有助于提高学生的临床思维能力.     

人体解剖生理学实验教学改革探究

人体解剖生理学实验的传统教学多以验证性实验为主,往往忽视各实验间的联系,且缺乏综合性和设计性实验项目.本课题在前期教学基础上,整合了实验教学内容、重构了实验教学体系.将人体解剖生理学实验分设为基础性实验、综合性实验和设计性实验三部分.通过该项目的实施,不仅提高了教学效率,而且也激发了学生的学习热情,同时也提高了学生的创新和探索能力.

Seasonal bone growth and physiology in endotherms shed light on dinosaur physiology

Cyclical growth leaves marks in bone tissue that are in the forefront of discussions about physiologies of extinct vertebrates. Ectotherms show pronounced annual cycles of growth arrest that correlate with a decrease in body temperature and metabolic rate; endotherms are assumed to grow continuously until they attain maturity because of their constant high body temperature and sustained metabolic rate. This apparent dichotomy has driven the argument that zonal bone denotes ectotherm-like physiologies, thus fuelling the controversy on dinosaur thermophysiology and the evolution of endothermy in birds and mammal-like reptiles. Here we show, from a comprehensive global study of wild ruminants from tropical to polar environments, that cyclical growth is a universal trait of homoeothermic endotherms. Growth is arrested during the unfavourable season concurrently with decreases in body temperature, metabolic rate and bone-growth-mediating plasma insulin-like growth factor-1 levels, forming part of a plesiomorphic thermometabolic strategy for energy conservation. Conversely, bouts of intense tissue growth coincide with peak metabolic rates and correlated hormonal changes at the beginning of the favourable season, indicating an increased efficiency in acquiring and using seasonal resources. Our study supplies the strongest evidence so far that homeothermic endotherms arrest growth seasonally, which precludes the use of lines of arrested growth as an argument in support of ectothermy. However, high growth rates are a distinctive trait of mammals, suggesting the capacity for endogenous heat generation. The ruminant annual cycle provides an extant model on which to base inferences regarding the thermophysiology of dinosaurs and other extinct taxa.     

Synchronization and rhythmic processes in physiology

Complex bodily rhythms are ubiquitous in living organisms. These rhythms arise from stochastic, nonlinear biological mechanisms interacting with a fluctuating environment. Disease often leads to alterations from normal to pathological rhythm. Fundamental questions concerning the dynamics of these rhythmic processes abound. For example, what is the origin of physiological rhythms? How do the rhythms interact with each other and the external environment? Can we decode the fluctuations in physiological rhythms to better diagnose human disease? And can we develop better methods to control pathological rhythms? Mathematical and physical techniques combined with physiological and medical studies are addressing these questions and are transforming our understanding of the rhythms of life.     

Heparan sulphate proteoglycans fine-tune mammalian physiology

Heparan sulphate proteoglycans reside on the plasma membrane of all animal cells studied so far and are a major component of extracellular matrices. Studies of model organisms and human diseases have demonstrated their importance in development and normal physiology. A recurrent theme is the electrostatic interaction of the heparan sulphate chains with protein ligands, which affects metabolism, transport, information transfer, support and regulation in all organ systems. The importance of these interactions is exemplified by phenotypic studies of mice and humans bearing mutations in the core proteins or the biosynthetic enzymes responsible for assembling the heparan sulphate chains.
