1葛洲坝水利枢纽工程截流后长江四大家鱼产卵场调查显示文摘本文报道了葛洲坝水利枢纽工程截流后长江四大家鱼产卵场情况。调查结果表明,长江干流上、中游四大家鱼产卵场的地理分布同60年代的调查结果基本相同。但其产卵总量仅为60年代调查结果的15.7%,资源量已严重衰减。产卵成色同60年代调查资料比较,草鱼和青鱼的比例显著增大,鳙鱼比例略有降低,而鲢鱼的比例显著下降。生殖群体结构已呈现简化(破坏),亲鱼个体变小,年龄组限减少,低龄鱼占群体数量的主导地位,初次性成熟的个体比重较大。调查表明,目前葛洲坝以上江段家鱼产卵数量占总量的36.4%,因此,在长江家鱼资源状况严重恶化的情况下,葛洲坝以上产卵场的地位就益显重要。鉴于葛洲坝水利枢纽工程阻隔了洄游生殖鱼类上溯产卵通道,葛洲坝应尽快修建过鱼设施,使草鱼等洄游性鱼类得以过坝上溯产卵,以保护或扩大四大家鱼及其他经济鱼类的资源。Survey Team of Spawning Grounds of Domestic Fishes in Chanjiang River 1982水产学报1982,6,4:74
2Distant hybridization leads to different ploidy fishes显示文摘Distant hybridization makes it possible to transfer the genome of one species to another, which results in changes in phenotypes and genotypes of the progenies. This study shows that distant hybridization or the combination of this method with gynogenesis or androgenesis lead to different ploidy fishes with genetic variation, including fertile tetraploid hybrids, sterile triploid hybrids, fertile diploid hybrids, fertile diploid gynogenetic fish, and their derived progenies. The formations of the different ploidy fishes depend on the genetic relationship between the parents. In this study, several types of distant hybridization, including red crucian carp (Carassius auratus red var.) (2n=100, abbreviated as RCC) (♀)×common carp (Cyprinus carpio L.) (2n=100, abbreviated as CC) (♂), and RCC (2n=100) (♀)×blunt snout bream (Megalobrama amblycephala) (2n=48, abbreviated as BSB) (♂) are described. In the distant hybridization of RCC (♀)×CC (♂), bisexual fertile F3–F18 allotetraploid hybrids (4n=200, abbreviated as 4nAT) were formed. The diploid hybrid eggs and diploid sperm generated by the females and males of 4nAT developed into diploid gynogenetic hybrids and diploid androgenetic hybrids, respectively, by gynogenesis and androgenesis, without treatment for doubling the chromosome. Improved tetraploid hybrids and improved diploid fishes with genetic variation were derived from the gynogenetic hybrid line. The improved diploid fishes included the high-body RCC and high-body goldfish. The formation of the tetraploid hybrids was related to the occurrence of unreduced gametes generated from the diploid hybrids, which involved in premeiotic endoreduplication, endomitosis, or fusion of germ cells. The sterile triploid hybrids (3n=150) were produced on a large scale by crossing the males of tetraploid hybrids with females of diploid fish (2n=100). In another distant hybridization of RCC (♀)×BSB (♂), different ploidy fishes were obtained, including diploid bisexual fertile natural gynogenetic fish (2n=100), sterile triploid hybrids (3n=124), and bisexual fertile tetraploid hybrids (4n=148). Furthermore, two kinds of pentaploid hybrids (5n=172 and 5n=198) were formed. The biological characteristics and the mechanisms of formation of the different ploidy fish were compared and discussed at the cellular and molecular level. The results indicated distant hybridization or the combination of this method with gynogenesis or androgenesis affects the formation of different ploidy fish with genetic variation.LIU ShaoJun Key Laboratory of Protein Chemistry and Fish Developmental Biology of Education Ministry of China, College of Life Sciences, Hunan Normal University, Changsha 410081, China 2010Science China(Life Sciences)2010,53,4:39
3Establishment of the diploid gynogenetic hybrid clonal line of red crucian carp × common carp显示文摘This study investigated the gynogenetic cytobiological behavior of the third gynogenetic generation (G3), which was generated from the diploid eggs produced by the second gynogenetic generation (G2) of red crucian carp × common carp, and determined the chromosomal numbers of G3, G2×scatter scale carp and G2×allotetraploid hybrids of red crucian carp × common carp. The results showed that the diploid eggs of G2 with 100 chromosomes, activated by UV-irradiated sperm from scatter scale carp and without the treatment for doubling the chromosomes, could develop into G3 with 100 chromosomes. Similar to the first and second gynogenetic generations (G1 and G2), G3 was also diploid (2n=100) and presented the hybrid traits. The triploids (3n=150) and tetraploids (4n=200) were produced by crossing G2 with scatter scale carp and crossing G2 with allotetraploids, respectively. The extrusion of the second polar body in the eggs of G2 ruled out the possibility that the retention of the second polar body led to the formation of the diploid eggs. In addition, we discussed the mechanism of the formation of the diploid eggs generated by G2. The establishment of the diploid gynogenesis clonal line (G1, G2 and G3) provided the evidence that the diploid eggs were able to develop into a new diploid hybrid clonal line by gynogenesis. By producing the diploid eggs as a unique reproductive way, the diploid gyno- genetic progeny of allotetraploid hybrids of red crucian carp × common carp had important signifi- cances in both biological evolution and production application.LIU ShaoJun, DUAN Wei, TAO Min, ZHANG Chun, SUN YuanDong, SHEN JiaMin, WANG Jing, LUO KaiKun & LIU Yun Key Laboratory of Protein Chemistry and Fish Developmental Biology of Education Ministry of China, College of Life Sciences, Hunan Normal University, Changsha 410081, China 2007Science China(Life Sciences)2007,50,2:21
4用理化方法诱导草鱼(♀)×团头鲂()杂种和草鱼的三倍体、四倍体显示文摘草鱼Ctenopharyngodon idellus(Cuv.et Val.)是我国劳动人民发现的并久经饲养的一种淡水鱼类养殖对象。它有生长快,草食性等优点。但抗病力低,特别是在鱼种阶段死亡率高,一般在60%左右,严重的可达80%以上。为了解决这一生产上的问题,在文化大革命初期(1966年)我们和本所官桥试验场的工人同志一起,“Domestic Fish”Research Group,Section of Fish Breeding,Second Laboratory,Institute of Hydrobiology,Hupei Province 1976水生生物学集刊1976,6,1:11
5散鳞镜鲤与兴国红鲤、龙州镜鲤的杂种优势以及鳞被、体色的遗传显示文摘本研究希望通过鲤鱼品种间杂交出现的杂种优势来提高鲤鱼的产量以及在杂种的后代中选择具有优良的经济性状的类型培育出新的鲤鱼品种。两组杂交的杂种一代具有明显的杂种优势,可以直接应用于渔业生产上并可望获得增产效果。根据对鳞被和体色的遗传特性的研究结果断定散鳞镜鲤与兴国红鲤的杂种二代中出现的红色镜鲤的鳞被和体色是由纯合型隐性基因控制的,可以预期它的后代不再出现分离而可能成为一个稳定的新品种。研究了不同品种及其杂种的血清蛋白聚丙烯酰胺盘状电泳图谱,希望借此作为一种选种的工具。Subgroup of Carp Studies,Section of Fish Breeding,Laboratory of Fish Genetics Breeding,Institute of Hydrobiology,Hupei Province 1975水生生物学集刊1975,5,4:11
6细鳞斜颌鲴的养殖及其生物学研究显示文摘细鳞斜颌鲴是在我国分布较广而又为群众所喜爱的一种野生经济鱼类。这种鱼在某些天然水体中可成为优势种群,产量较大,最高可以占总渔获量的50%以上。但有许多水体中却没有这种鱼或数量不大。通过试验和研究,我们已能对这种鱼进行大规模的人工繁殖和苗种培育,近年来,已将数万尾大规格鱼种投放到一原来只投放“家鱼”(泛指鲩、青、鲢、鳙,以下均同)的水库中,并将检验其增产效果。实践证明斜颌鲴在池塘中与现有“家鱼”混养时,非但不影响“家鱼”的生长,并可使池塘总产量增加10%以上;原因是这种鱼主要以其他养殖鱼类尚未利用或未能充分利用的腐屑、腐泥和着生藻类为食物。该鱼头两年生长较快,两周年可达一市斤左右,并第一次达到性成熟,这种规格的鱼上市就是经济价值高的优良食用鱼。因其在池塘中易于捕捞,故也是丰产塘中轮捕轮放的好对象。按普通“家鱼”种的培育方法当年鱼可养成4寸左右,第二年底都能在半斤以上,大的可达8两半。由于该鱼头小肉多而味美,故即使2—3两重的鱼在市场上也受到顾客的欢迎。本文还介绍了养殖这种鱼的方法及其有关的生物学资料,并讨论了在天然水体中促使这种鱼增产的可能途径。Administrative Board of the Tao-Yuan-Ho Reservoir,Hupei Province Section of Introduction Acclimation,Laboratory of Fish Genetics Breeding,Institute of Hydrobiology,Hupei Province 1975水生生物学集刊1975,5,4:10
7多普勒信号分析技术的比较研究显示文摘有好几种信号处理技术被应用于超声多普勒信号的分析.为了在平均频率估计的准确性和频谱展宽检测的敏感性上对各种方法加以优化,并比较这些不同处理方法的性能,该文研究了短时快速傅立叶交换、快速傅立叶变换结合平稳性提高的方法、改进的协方差估计法以及包括伪Wigner-Ville分布和Choi-Williams分布的时间-频率分析方法.通过模拟实验,得出了时间-频率分析方法可适用于多普勒信号的分析,参数估计方法和快速傅立叶变换结合平稳性提高的方法也有较好的分析性能.同时发现,当使用短时快速傅立叶变换分析多普勒信号时,以选用10ms的Hanning窗较为合适.汪源源 Fish,PJ 1996复旦学报(自然科学版)1996,35,1:7

121型糖尿病患儿低血糖时升糖激素反应的特异性研究进展显示文摘糖尿病是最常见的儿科内分泌疾病之一,低血糖已成为限制儿童糖尿病控制的主要障碍.若不及时诊治,可导致严重的脑损伤,生长发育受限甚至死亡.近年来,越来越多的学者关注小儿低血糖时升糖激素的反调节作用.回顾相关研究,认识儿童糖尿病患者低血糖时升糖激素反应的特异性,对糖尿病患儿低血糖的防治十分重要.都书婕 Anne Foha Fish 楼青青 2017中华现代护理杂志2017,23,21:3
13Olfactory receptor gene family evolution in stickleback and medaka fishes显示文摘Interaction of olfactory receptor (OR) genes with environmental odors is regarded as the first step of olfaction.In this study,OR genes of two fish,medaka (Oryzias latipes) and stickleback (Gasterosteus aculeatus),were identified and an evolutional analysis was conducted.The selection pressure of different TM regions and complete coding region were compared.Three TM regions (TM4,TM5 and TM6) were found to have higher average Ka/Ks values,which might be partly caused by positive selection as suggested by subsequent positive selection analysis.Further analysis showed that many PTSs overlap,or are adjacent to previously deduced binding sites in mammals.These results support the hypothesis that binding sites of fish OR genes may evolved under positive selection.CHEN Ming1,2,PENG ZuoGang1 & HE ShunPing1 1 Laboratory of Fish Phylogenetics and Biogeography,Institute of Hydrobiology,Chinese Academy of Sciences,Wuhan 430072,China 2 Graduate University of Chinese Academy of Sciences,Beijing 100039,China 2010Science China(Life Sciences)2010,53,2:3

15Development of a laser capture microscope-based single-cell-type proteomics tool for studying proteomes of individual cell layers of plant roots显示文摘Single-cell-type proteomics provides the capability to revealing the genomic and proteomics information at cell-level resolution.However,the methodology for this type of research has not been well-developed.This paper reports developing a workflow of laser capture microdissection(LCM)followed by gel-liquid chromatography-tandem mass spectrometry(GeLC-MS/MS)-based proteomics analysis for the identification of proteomes contained in individual cell layers of tomato roots.Thin-sections(~10-μm thick,10 sections per root tip)were prepared for root tips of tomato germinating seedlings.Epidermal and cortical cells(5000–7000 cells per tissue type)were isolated under a LCM microscope.Proteins were isolated and then separated by SDS–polyacrylamide gel electrophoresis followed by in-gel-tryptic digestion.The MS and MS/MS spectra generated using nanoLC-MS/MS analysis of the tryptic peptides were searched against ITAG2.4 tomato protein database to identify proteins contained in each single-cell-type sample.Based on the biological functions,proteins with proven functions in root hair development were identified in epidermal cells but not in the cortical cells.Several of these proteins were found in Al-treated roots only.The results demonstrated that the cell-type-specific proteome is relevant for tissue-specific functions in tomato roots.Increasing the coverage of proteomes and reducing the inevitable cross-contamination from adjacent cell layers,in both vertical and cross directions when cells are isolated from slides prepared using intact root tips,are the major challenges using the technology in proteomics analysis of plant roots.Yingde Zhu Hui Li Sarabjit Bhatti Suping Zhou Yong Yang Tara Fish Theodore W Thannhauser 2016Horticulture Research2016,3,1:2

18胰岛素注射指南有循证依据吗?各国胰岛素注射指南的系统评价显示文摘目的系统评价各国胰岛素注射指南关于针头是否重复使用、轮换注射部位的方法、不同胰岛素注射不同部位以及注射针头长度的循证依据。方法计算机检索PubMed、Medline、Embase、中国知网、维普数据库、万方数据库(1946年1月至2016年12月),搜索美国、澳大利亚、加拿大、丹麦、中国香港、荷兰、英国糖尿病教育学会官网(至2016年12月),按纳入和排除标准纳入胰岛素注射指南。两名研究人员根据指南研究和评价标准独立筛选并评价纳入指南的质量,提取相关数据进行评价。结果初检出相关文献967100篇,最终纳入10项指南,均发表于2007至2016年之间。系统评价发现,就各指南引用的证据而言,一针一用、在不同区域轮换注射(即大轮换,区别于同一部位轮换)以及不同胰岛素(如短效、中效等)应注射不同区域的建议所引用的依据缺乏准确性。结论现有胰岛素注射指南的部分建议证据引用不充分,将来需要开展更多与胰岛素注射相关的临床随机对照试验,为胰岛素注射指南的制定提供科学依据。左盼盼 李凡 Fish Anne Folta 楼青青 2020中华糖尿病杂志2020,12,2:2
