Most phylogeographical studies of postglacial colonization focus on high latitude locations in the Northern Hemisphere. Here, we studied the phylogeographical structure of the red-necked snow finch Pyrgilauda ruficollis, an endemic species of the Tibetan plateau. We analysed 879 base pairs (bp) of the mitochondrial cytochrome b gene and 529 bp of the(More)
The 2004 outbreaks of highly pathogenic avian influenza H5N1 disease in China led to a great poultry loss and society attention. A survey of avian influenza viruses was conducted on tree sparrows (Passer montanus) collected in China in 2004. Four viruses were isolated from free-living tree sparrows. The results of the whole-genome analysis indicated that an(More)
Objective:To investigate the anti-obesity effects of the pomegranate leaf extract (PLE) in a mouse model of high-fat diet induced obesity and hyperlipidemia.Design:For the anti-obesity experiment, male and female ICR mice were fed with a high-fat diet to induce obesity. When the weight of the high-fat diet group was 20% higher than the normal diet group,(More)
Long non-coding RNAs (lncRNAs) have a critical role in cancer initiation and progression, and thus may mediate oncogenic or tumor suppressing effects, as well as be a new class of cancer therapeutic targets. We performed high-throughput sequencing of RNA (RNA-seq) to investigate the expression level of lncRNAs and protein-coding genes in 30 esophageal(More)
In this paper, we present a method using webpage segmentation algorithm to improve the performance of the webpage content extraction. The traditional methods often depend on parsing the DOM tree of the webpage and judging each node of the DOM tree to determine which node is the text node, this kind of method has a potential problem, it sometimes throws part(More)
The aim of this study was to investigate the mechanisms underlying the involvement of gut microbes in body weight gain of high-fat diet-fed obesity-prone (obese) and obesity-resistant (lean) mice. C57BL/6 mice were grouped into an obese group, a lean group and a normal control group. Both obese and lean mice were fed a high-fat diet while normal control(More)
In common with human speech, song is culturally inherited in oscine passerine birds ('songbirds'). Intraspecific divergence in birdsong, such as development of local dialects, might be an important early step in the speciation process. It is therefore vital to understand how songs diverge, especially in founding populations. The northward expansion of the(More)
This paper proposes a watermarking algorithm based on curvelet transform. Considering the characteristics of Human Visual System (HVS), the algorithm extract the embedding field of one image using curvelet transforms. Then the watermark is embedded the embedding field. A scheme for detect and recovering rotation attacks is applied before watermark(More)
Multilocus data from the different genomes are essential to understand the phylogeographic history of species, particularly when a species has the male-biased dispersal pattern. Although Black-throated tits (Aegithalos concinnus) are socially monogamous and cooperatively breeding birds, limited observational data suggested that males may have the ability of(More)
Marine microorganisms continue to be a productive focus for much of marine natural products investigation.1–3 These organisms flourishing in diverse marine environments, have produced a wide variety of structurally unique and biologically active secondary metabolites many of which have attracted considerable attention.1,4 In the last decades, the number of(More)
