用柱层析和TLC分离小麦PGIP和植保素

植物抗病能力大小的测定需要比较准确可靠且相对简便的办法。采用接种病菌于植物上观察染菌情况虽然直观，但受病菌本身的生理状态及外界环境影响很大，且不便于定量的表述。因此，选择合适的生理生化指标作为植物抗性大小的衡量标准，对于植物病理的研究具有重要的意义。选择了小麦体系的两种抗性物质－ 小麦植保素和 Ｐ Ｇ Ｉ Ｐ作为小麦的抗性指标来分离分析

An approach to identify the functional transduction and transmission of an activated pathway

In this study, we investigated the features of latency-amplitude (L-A) functions at different sound frequencies, using extracellular recording from auditory neurons in the central nucleus of the inferior colliculus (ICC) in mice. Isofrequency L-A functions from single neurons could be fit with a newly developed equation based on Pieron’s law. The high degree of fitness indicates that the curvatures of all isofrequency L-A functions for a given neuron are similar, and that the difference between L-A functions is due to a shift in their positions in the coordinate system. When we normalized the L-A functions to match the position of the L-A function obtained at the neuronal characteristic frequency (CF), all isofrequency L-A functions from a given ICC neuron were highly superimposed. The similar shapes of the L-A functions at different frequencies may reflect the physical laws of sound being transferred into bioelectric signals. The position of a non-CF L-A function could be measured as the differences of the asymptotic L and A ( L and A) compared to the L-A function at a reference frequency such as the CF. The nerve fibers and synapses connecting to a neuron for acoustic information processing can be functionally simplified as a single "wire" (as the total length of nerve fibers) and "joint" (as the summated size/strength of synapses). The wire and joint mediate information transmission and transduction, respectively. Thus, L and A may be measurements of the total length of nerve fibers and the strength of summated synapses in the activated auditory pathway. L and A differed between frequency channels and neurons, suggesting that the differences of acoustic neuronal responses are always caused by activation of different pathways, and that the pathways that process sounds are diverse.     

试论居住环境的可防卫性

通过对现代居住环境安全防卫功能缺失原因的分析，结合我国传统居住环境的可防卫特点及西方学者对可防御空间的研究成果，认为环境本身具有安全防御的功能，居住环境的规划设计不应仅局限于形式上的追求，而应通过环境与人的互动关系的研究，创造具有领域性和归属感的室外空间环境，诱导良好的邻里关系的产生，提高居住环境的可防卫性。
