Statures in Han populations of China

<正>Dear Editor,Shortly after initiating the"Physical Anthropological Research on Han Chinese"research project,we applied uniform sampling methods as well as methods and instruments of measurement to obtain a complete set of measurements of physical anthropological indicators among Han populations across China.Among these measurements,body stature was a key indicator.Currently,there should be reliable     

A new chapter for China's public health security——aids offered to Africa to combat Ebola

<正>As one of the most deadly diseases,the outbreak of Ebola virus disease(EVD)is causing panic in West Africa and posing alarms globally.Since the re-emergence of EVD,China authority has been consistently providing support for Africa in its fight against Ebola.On September 16,2014,a laboratory testing team and a medical team,consisting of 59public health experts and medical staffers,were dispatched to assist local hospitals in West African countries to set up lab screening and clinical treatment of EVD(http://www.taiwan.cn/xwzx/Technology/201409/t20140917_7354545.     

An Effective Method for Raising Antisera Against β-defensins: Double-copy Protein Expression of mBin1b in E. coli

Defensins are a family of evolutionarily relatedvertebrate antimicrobial peptides with a characteristicβ-sheet-rich fold and a framework of six disulphide-linkedcysteines. The two main defensin subfamilies, α- andβ-defensin, differ in the length of pep…

The impact of special issues

With support from many authors from many different scientific fields,Zoological Research(ZR)successfully released eight special issues from 2011 to 2014 on various topics,including Animal Ecology and Resources,Animal Genetic Diversity,Development and Evolution,Fish Diversity and Primates and Animal Models of Human Diseases.These special issues strongly align with our aims and scope,which have been     

转基因抗除草剂油菜对近缘作物的基因漂移

以转基因抗除草剂油菜 Q3和 HCN- 19为花粉供体材料 ,油菜近缘作物为花粉受体材料 ,在自然授粉条件下研究甘蓝型油菜与芸薹属近缘作物间的基因漂移频率。结果表明 ,油菜对芸薹属 6个种甘蓝、黑芥、埃芥、芥菜型油菜、白菜型油菜和甘蓝型油菜的基因漂移率分别为 0、0 .0 2 4 %～ 0 .2 4 3%、 0 .0 2 8%～ 0 .0 92 %、 0 .10 9%～ 0 .95 1%、 0 .4 79%～ 0 .879%、 1.2 5 2 %～2 .191%。且基因漂移频率受多种因素影响 ,其中与杂交亲和性、花期同步率、种植面积等高度相关。通过花粉将抗除草剂基因漂移给近缘作物 ,油菜是需要特别关注的作物     

Genetic divergence among geographical populations of the migratory locust in China

The migratory locust, Locusta migratoria L., which is distributed widely in the East Hemisphere, has long been regarded as the most important agricultural pest and a model insect. Its distribution ranges from thetropic and the subtropical zone, to the temperate zone, and to the cold-temperate zone. Because of the wide geographical distribution and adaptations, many geo- graphical populations of the migratory locust dis- played apparent variation in morphology, life history, physiology, and ot…     

Alien DNA introgression and wheat DNA rearrangements in a stable wheat line derived from the early generation of distant hybridization

In general, it requires five or more generations to develop a stable line by the traditional breeding method of cultivar hybrids in self-pollinated crops, such as wheat, barley, and rice. No doubt, the breeding period will be shortened and thus the breeding effi-ciency will be improved if the hybrids can stabilize in early generation. The method of haploid breeding, that is, obtaining stable pure lines (DH lines) of cultivar hybrids with the aid of anther culture and then chro-mosome doubling,…     

Human pescadillo induces large-scale chromatin unfolding

Pescadillo was initially identified in a genetic screen for mutations that affect embryonic develop-ment of the zebrafish Daniorerio[1]. Pescadillo-/- ze-brafish mutants showed abnormal embryonic devel-opment such as reduced brain, eye size and a lack of extension of the jaw on developmental day 3. Further study showed that the Pescadillo protein is mainly distributed in tissues containing a significant number of proliferating cells and dramatically elevated in ma-lignant human astrocytomas an…     

Multi-locus association study of schizophrenia susceptibility genes with a posterior probability method

Schizophrenia is a serious neuropsychiatric illness affecting about 1% of the world’s population. Family, twin and adoption studies have demonstrated that 65%―85% of the susceptibility to schizophrenia can be attributed to genes. On the basis of genetic model-ing of epidemiological data and recent results of a number of whole-genome screens for susceptibility genes, schizophrenia has been considered a complex disorder. A number of genes with small to moderate effects are involved in combinat…
