1Wolbachia pipientis wMel基因组水平上的密码子使用分析显示文摘本实验检测了黑腹果蝇的专性寄生菌Wolbachia pipientis wMel基因组的密码子使用模式,并推测影响其密码子组成的因素.选择了478条蛋白编码基因作为研究对象,它们的GC含量比较低,约0.282~0.432.本研究结果显示,关联突变(context-dependent mutation)是影响W.pipientis wMel基因组密码子组成的主要因素.同时,Nc—Plot曲线显示,基因组的密码子组成还受到了核苷酸组成偏好性(nucleotide composition bias)的影响.对应分析的结果显示,基因长度(R=0.123,P〈0.01)和基因表达水平(R=-0.312,P〈0.01)也对基因组的密码子使用偏好性起到了一定的作用.因此,关联突变、核苷酸组成、基因长度和基因表达水平都会影响到基因组的密码子使用偏好性.Wolbachia基因组的几个特征和动物线粒体基因组具有较高的相似性,而且现在已有报道说明它们有共同的起源,但仍需进一步验证.孙铮 马亮 MURPHY Robert 张宪省 黄大卫 2009中国科学(C辑)2009,39,10:17

4Genetic consequences of postglacial colonization by the endemic Yarkand hare (Lepus yarkandensis) of the arid Tarim Basin显示文摘Orogenesis of the Qinghai-Tibetan Plateau,which occurred in a stepwise manner,contributed to the extreme aridity of the Tarim Basin,resulting in vulnerable and unstable ecosystems.Quaternary climatic oscillations may have affected the ecosystems and,consequently,the distributions and genetic structuring of the Tarim Basin's biota.We used nucleotide sequence data from 2 mitochondrial (mt) DNA genes (Cyt b and the D-loop) to test hypotheses associated with the matrilineal and demographical histories of the Tarim Basin's endemic Yarkand hare (Lepus yarkandensis).Range-wide sampling involving 20 populations and 224 individuals detected 126 haplotypes that clustered into 5 major lineages in both the phylogenetic tree and median-joining network.Populations from the northern and eastern Tarim Basin shared a similar history,as did those from the western and southern regions.Demographical analysis and genetic diversity estimations suggested that the western and southern regions might have served as glacial refugia for the Yarkand hare during Quaternary climatic oscillations.The distribution of the Yarkand hare,especially in the northern and eastern parts,probably represented 3 postglacial colonization events,dated to 0.21,0.090 and 0.054 MYA,which corresponded to known interglacial periods.Given the relatively complete geographic isolation between the eastern and southern populations,the Yarkand hare likely dispersed during postglacial periods from the southwest to the north,and then onward to the east.The absence of water likely forced the species into refugia,and this differed from other Pleistocene biogeographical drivers.The demographical and historical patterns have important implications for conservation.SHAN WenJuan LIU Jiang YU Li ROBERT W.

5外群选择对隧蜂科(膜翅目:蜜蜂总科)系统重建的影响(英文)显示文摘外群用于给树附根和推断祖先性状状态。通常,来自内群的姐妹群中的多个分类单元被共同选择作为外群。为了在经验上验证这一方法,我们采用了3种外群选择策略:姐妹群中的单一分类单元,姐妹群中的多个分类单元和连续姐妹群中的多个分类单元。以隧蜂科(膜翅目:蜜蜂总科)的系统发育重建为例,我们评估了这3种策略对树拓扑结构的影响,包括最大似然树、最大简约树和贝叶斯树。初步结果表明:相比其他两种策略,采用姐妹群中的多个分类单元作为外群更有利于系统发育重建得到现已被广泛认可的隧蜂科系统发育关系;相比最大似然法和贝叶斯法,虽然隧蜂科系统发育关系没有被很好地解决,但最大简约法在不同外群选择策略下得到了较为一致的拓扑结构。罗阿蓉 张彦周 乔慧捷 史卫峰 Robert W.

8Low prevalence of epilepsy and onchocerciasis after more than 20 years of ivermectin treatment in the Imo River Basin in Nigeria显示文摘Background:High epilepsy prevalence and incidence have been reported in areas with high onchocerciasis transmission.Recent findings suggest that proper community-directed treatment with ivermectin(CDTI)is potentially able to prevent onchocerciasis-associated epilepsy(OAE).We assessed the epilepsy prevalence and onchocerciasis transmission in two Nigerian villages following more than 20 years of CDTI.Methods:A cross-sectional door-to-door survey was performed in two villages in the Imo River Basin reported to be mesoendomic for onchocerciasis(Umuoparaodu and Umuezeala).Individuals were screened for epilepsy using a validated 5-item questionnaire.Persons suspected to have epilepsy were examined by a neurologist or a physician with training in epilepsy for confirmation.Onchocerciasis was investigated via skin snip microscopy and rapid diagnostic tests for Ov16 antibodies.Results were compared with previous findings from the Imo river basin.Results:A total of 843 individuals from 257 households in the two villages were encountered.We detected four persons with epilepsy(PWE)giving a crude epilepsy prevalence of 0.5%.This finding differs from observations reported 14 years ago which showed an epilepsy prevalence of 2.8%in the neighbouring village of Umulolo(P=0.0001),and 1.2%from 13 villages in the Imo river basin(P=0.07).The seroprevalence of Ov16 antibodies was found to be 0%.Only 4.6%of skin snips were positive compared to 26.8%in previous surveys(P<0.0001).Ivermectin mass distribution coverage in the study sites in 2017 was 79.7%.Conclusions:A low epilepsy and onchocerciasis prevalence was observed following more than 20 years of CDTI in the Imo River Basin.Absence of Ov16 antibodies indicates minimal transmission of onchocerciasis.These results contrast with observations from areas of high onchocerciasis transmission,where epilepsy prevalence and incidence remain high.Findings from this study suggest that sustained efforts could eventually achieve elimination of onchocerciasis in these villages.Joseph N.F.Siewe Chinyere N.Ukaga Ernest O.Nwazor Murphy O.Nwoke Modebelu C.Nwokeji Blessing C.Onuoha Simon O.Nwanjor Joel Okeke Kate Osahor Lilian Chimechefulam Ann I.Ogomaka Augustine A.Amaechi Chika I.Ezenwa Monika N.Ezike Chidimma I.kpeama Ogechi Nwachukwu Austine I.Eriama-Joseph Berthram E.B.Nwoke Robert Colebunders 2019Infectious Diseases of Poverty2019,8,1:2

11H5N1禽流感病毒血凝素基因密码子的变异显示文摘应用固定效应似然模型研究了作用于H5N1禽流感病毒血凝素基因的选择压力.研究发现,除2000年以外,1997—2007年,H5N1病毒的血凝素基因都受到正选择压力的作用.东南亚、中国香港和中国大陆的血凝素序列氨基酸多态性最复杂,并且具有相似的非同义突变模式.大部分地区的H5N1病毒血凝素基因的一些位点受到正选择压力的影响,并且其中一些位点在不同地区的病毒中具有不同的氨基酸模式.另外,正选择压力对分离自欧洲、非洲和俄罗斯以及不同宿主类型的H5N1病毒产生了不同的影响.一个位点只在取自人类的病毒中被发现受到正选择压力的影响.尽管一些受到正选择压力的位点的功能尚不清楚,但是本文的分析提供了H5N1禽流感病毒适应不同时间、地点和寄主的遗传证据.史卫峰 Mark J Gibbs 张彦周 庄东明 顿爱社 于广福 杨娜娜 Robert W Murphy 朱朝东 2008中国科学(C辑)2008,38,10:2
