体育运动中神经-肌肉疲劳研究的新进展

简要回顾神经-肌肉疲劳的研究历史,并从生理学角度综述近年来国内外有关中枢性疲劳与外周疲劳的理论研究成果以及在实验研究方面取得的新进展.有关中枢性疲劳,着重介绍5-羟色胺、多巴胺、乙酰胆碱等中枢神经递质参与运动性疲劳的形成与恢复的新证据与新理论(可能的机制).有关外周疲劳机制,从神经肌肉接头处的超微结构到骨骼肌细胞的亚细胞结构等可能发生疲劳的部位,将近年来的研究成果作简要概括.这些研究成果表明有关运动性疲劳的生理学研究进入到亚细胞水平与分子水平.     

Canaletto’s paintings open a new window on the relative sea-level rise in Venice

The paintings by Canaletto (1697–1768), made with the help of a camera obscura, are just like real photographs, documenting as they do the Venice of the XVIII century with an accurate reproduction of all the details. The brown–green front left by the Laminaria, an alga living between the high and low tide, constitutes a precise biological indication of the average level of the high tide. By comparing the level of this front at Canaletto’s time with the present level, we can calculate/discover the relative sea level rise which has occurred in the last two and a half centuries.

中州武术文化研究

在中华文化大环境下孕育的中国武术，具有明显的地域性和民族特点。以中州武术为研究对象，以区域文化为视角，借鉴人类学、民俗学、历史学、社会学等诸多学科的研究方法及相关研究成果，从文化空间特征及其联系的角度对中州武术文化形态进行系统研究，认为中州武术丰厚多样，其形成和发展是与中州地域的特定地理环境、政治和经济的影响以及社会习武风尚的作用密切相关的；中州武术文化的主体性、兼容性、辐射性和创新性构成了中州武术文化最为明显的地域文化特征；中州武术客体文化呈现出多元的武术文化模式．

Seeking Nettle Textiles – Utilizing a Combination of Microscopic Methods for Fibre Identification

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history.

自闭症认知缺陷的神经机制研究进展

本文对自闭症认知神经机制研究进行了系统回顾。结果表明 ,自闭症的心理推测能力缺陷可能与右侧眶额皮质、左内侧前额皮质及包括杏仁核在内的内侧颞叶等脑区的损伤有关 ;中枢性统合不足可能与小脑病变有关 ;执行功能障碍可能与额叶、基底节异常有关。现有研究结果相当不一致 ,有关上述三种理论及其相互关系的探讨还存在很多争议。
