The retrieval of DNA from ancient human specimens is not always successful owing to DNA deteriora-tion and contamination although it is vital to provide new insights into the genetic structure of ancient people and to reconstruct the past history. Normally, only short DNA fragments can be retrieved from the ancient specimens. How to identify the authenticity of DNA obtained and to uncover the information it contained are difficult. We employed the ancient mtDNAs reported from Central Asia (including Xin-jiang, china) as an example to discern potentially extraneous DNA contamination based on the updated mtDNA phylog-eny derived from mtDNA control region, coding region, as well as complete sequence information. Our results demon-strated that many mtDNAs reported are more or less prob-lematic. Starting from a reliable mtDNA phylogeney and combining the available modern data into analysis, one can ascertain the authenticity of the ancient DNA, distinguish the potential errors in a data set, and efficiently decipher the meager information it harbored. The reappraisal of the mtDNAs with the age of more than 2.00 years from Central Asia gave support to the suggestion of extensively (pre)historical gene admixture in this region.

Two multigene superfamilies, named V1R and V2., encoding seven-transmembrane-domain G-protein coupled receptors (GPCRs) have been identified as pheromone receptors in mammals. Three V2. gene families have been described in mouse and rat. Here we screened the updated mouse genome se- quence database and finally retrieved 63 putative functional V2. genes including three newly identified genes which formed a new additional family. We described the genomic organization of these genes and also characterized the conservation of mouse V2. protein sequences. These genomic and se- quence information we described are useful as part of the evidence to speculate the functional domain of V2.s and should give aid to the functionality study in the future.

This paper reviews a large number of genes under positive Darwinian selection in modern human populations, such as brain development genes, immunity genes, reproductive related genes, perception receptors. The research on the evolutionary property of these genes will provide important insight into human evolution and disease mechanisms. With the increase of population genetics and comparative genomics data, more and more evidences indicate that positive Darwinian selection plays an indispensable role in the origin and evolution of human beings. This paper will also summarize the methods to detect positive selection, analyze the interference factors faced and make suggestions for further research on positive selection.

Mitochondrial disease currently received an increasing concern. However, the case-control design commonly adopted in this field is vulnerable to genetic background, population stratification and poor data quality. Although the phylogenetic analysis could help solve part of these problems, it has not received adequate attention. This paper is a review of this method as well as its application in mito- chondrial disease study.

The Global Invasive Species Database, GISD, comprises 2. species of the most significant invasive alien insects in the world (through November, 2.05), 6 of which are originally native to china, 11 are established in china, and 10 have a potential invasion threat to china. This paper discusses these species in terms of distribution, harmfulness and dispersal ways, and finds that: (i) Information re-garding invasive insects in the GISD remains inadequate. Such harmful invasive species as Opogona sacchari (Bojer), Oracella acuta (Lobdell), and Dendroctonus valens LeConte are not included. (ii) Ten species of invasive insects, particularly Lasius neglectus Van Loon and Linepithema humile (Mayr) which become established in areas near china, have the potential to become established in china. (iii) Special attention should be paid to species from Asia and the Americas because of their greater likeli-hood of becoming established in china. Finally, some management strategies including legislation, quarantine, early warning, prevention and control are suggested.

Molecular evolution of stress-response gene Leptin in high-altitude chinese snub-nosed monkeys (Rhinopithecus genus)

chinese snub-nosed monkeys (genus Rhinopithecus, subfamily Colobinae), including R. bieti, R. brelichi and R. roxellana, are well-known as the non-human primates with the highest known altitudinal distribution. They represent an interesting model organism of adaptation to the extreme environmental stresses. However, no study at the molecular level has yet been reported for the high-altitude adaptation in chinese snub-nosed monkeys. Leptin, as an adipocyte-derived hormone, is believed to play an important role in energy homeostasis in adaptation to high altitude environments. In the present study, we sequenced and compared leptin sequences of the chinese snub-nosed monkeys (R. bieti and R. roxellana) with their lowland close relative R. avunculus and other Colobines. Unexpectedly, no amino acid changes were observed in the 7 Colobinae species examined, including the 2.chinese snub-nosed monkeys, indicating no difference in the evolutionary pattern of the Leptin gene between high-altitude monkeys and their lowland counterparts. In contrast to a previous finding of adaptive evolution of Leptin gene in plateau pikas, our study suggests that this gene may not have an important role in high-altitude adaptation of chinese snub-nosed monkeys. Other nuclear genes associated with energy metabolism, or mitochondrial genes, are most likely to be involved the molecular mechanism underlying adaptation of these monkeys to cold and hypoxia associated with the highland environment.

A mixed method for measuring low-frequency acoustic properties of macromolecular materials

A mixed method for measuring low-frequency acoustic properties of macro-molecular materials is presented. The dynamic mechanical parameters of materials are first measured by using Dynamic Mechanical Thermal Apparatus(DMTA) at low frequen-cies,usually less than 100 Hz; then based on the Principles of Time-Temperature Super-position (TTS),these parameters are extended to the frequency range that acousticians are concerned about,usually from hundreds to thousands of hertz; finally the extended dynamic mechanical parameters are transformed into acoustic parameters with the help of acoustic measurement and inverse analysis. To test the feasibility and accuracy,we measure a kind of rubber sample in DMTA and acquire the basic acoustic parameters of the sample by using this method. While applying the basic parameters to calculating characteristics of the sample in acoustic pipe,a reasonable agreement of sound absorp-tion coefficients is obtained between the calculations and measurements in the acoustic pipe.
