The results show that these three genes represent circadian rhythms in different regimes in scn , while they only show markedly circadian rhythms in constant dark in lymphocytes 结果发现, scn中三个基因的表达在不同光制下都存在昼夜节律,外周只有全黑暗条件下有明确的昼夜节律。
But because sunlight or other bright lights can reset the scn , our biological cycles normally follow the 24 - hour cycle of the sun , rather than our innate cycle 但是由于日光和其它光线可以重新设定scn ,所以我们的生物钟周期通常是随着太阳的24时周期,而不是我们原本先天的周期时间。
Sd rats were housed in different regimes for at lest three weeks before experiment . animals of 3 weeks anaesthetized by ether in set conditions , were sampled from the scn and blood every four hours in a circadian day 不同光制饲养三周以上的sd大鼠,在一个昼夜时间内每隔四小时采样一次,每个时点三只大鼠。
Basis of rhythmic structure is circadian clock , which is located at suprachiasmatic nucleus ( scn ) and pineal gland in mammal . the molecular basis of which is composed of a series of genes and their corresponding protein products 生物节律的生理基础是生物钟,哺乳动物的主钟定位于丘脑视交叉上核( suprachiasmaticnucleus , scn )和松果体;生物节律的分子基础是一系列与生物钟相关的基因及其蛋白产物。
( 2 ) both the circadian clock and the light signal may affect the circadian expressions of the mt1 and mt2 genes . the mt1 is more sensitive to variation with the structure of light and dark , but the mt2 is more affected by the time length of light exposure 光照对scn及淋巴细胞中钟相关基因昼夜表达节律的影响中文摘要血和血的昼夜节律性表达同时受生物钟及光信号的影响,但mt受光制构成的影响较大,而航2受光照时间长短的影响较大。
The softswitch is the core technology of the next generation network , for it can be the core to offer calling , control and service for voice service , data service and video service in the next generation network , and it also plays the key role in the evolvement of scn to the psn 软交换是下一代网络的核心技术,因为它可以成为下一代分组网络中为语音业务、数据业务和视频业务提供呼叫、控制和业务的核心,同时也是电路交换网向分组网演进的关键。
2 . ne - evoked contraction was not significantly changed after the extracellular na + was replaced by choline and c4h12n + , but was relaxed when the extracellular cl - was replaced by glutamate and gluconate . moreover , the vasoconstriction induced by ne was further enhanced with the replacement of the extracellular cl " by br " and scn " , which was still sensitive to either nfa or nppb 用氯化胆碱和四甲基氯化按分别替代灌流液中的氯化钠后血管张力无明显变化,在此基础上nfa 、 nppb仍能抑制血管收缩,引起血管完全舒张;用通透性低的阴离子谷氨酸根和葡萄糖酸根分别替代灌流液中的q后血管发生舒张;用通透性高的阴离子br和scn分别替代灌流液中的ci后血管张力增加,并能被nfa 、 nppb所抑制。
This paper discusses some important technologies closed to dtv receiving system deeply , base on scn and cctv . it includes mpeg - 2 system level , dvb service information , conditional acceptance . it also describes how to realize epg , ca , upgrade on line etc based on the dtv service information technology at lengtho now , the production of this design is applied to the digital tv products of cctv and sichuan tv net 本论文结合数字电视在四川广电网和cctv的具体应用情况,深入研究探讨了与数字电视接收系统紧密相关的部分关键技术,包括mpeg - 2系统层结构分析、 mpeg - 2和dvb业务信息分析、数字电视条件接收基本原理和加解扰及加解密技术,并详细叙述了如何运用数字电视业务信息技术实现了电子节目指南、条件接收、在线升级等基本业务。
( n the world the traditional in - service training is a from - up - down system , dominated by government - turn crsity - collcgc for advanced studies , which is outside - controlled and ineffective , fn the past 2 " years , ( he developed countries such england and us have began to move down the heart of teacher ' s in - scn ice training , try to make the school - based teacher training into the major part of in - service training 这样,在过去20多年中,以英、美等发达国家为代表,开始把教师在职培训的重心下移,尝试把教师校本培训作为在职培训的重要组成部分,因为它的针对性强,全员参与,能调动教师的积极性,所以使校本培训受到各国普遍的欢迎与关注,成为教师在职培训体系的重要组成部分。
