Ice-sheet development in Antarctica was a result of significant and rapid global climate change about 34 million years ago. Ice-sheet and climate modelling suggest reductions in atmospheric carbon dioxide (less than three times the pre-industrial level of 280 parts per million by volume) that, in conjunction with the development of the Antarctic Circumpolar(More)
Selenium (Se), selenoprotein N (SelN) and selenoprotein W (SelW) play a crucial role in muscle disorders. Se status highly regulates selenoprotein mRNA levels. However, few attempts have been performed on the effect of dietary Se supplementation on muscle SelN and SelW mRNA levels in birds. To investigate the effects of Se on the regulation of SelN and SelW(More)
Buerger's disease, also known as thromboangiitis obliterans, is a nonatherosclerotic, inflammatory, vasoocclusive disease. It is characterized pathologically as a panangiitis of medium and small blood vessels, including both arteries and adjacent veins, especially the distal extremities (the feet and the hands).

PURPOSE Prostate cancer (PC) is the most common malignant disease in males and the second leading cause of cancer related deaths in men in developed countries. The purpose of this study was to investigate whether microRNA (miR)-150 is a factor influencing survival in prostate cancer patients. METHODS miR-150 mRNA and protein expression levels in prostatic(More)
Image search on web is very familiar to various users, and improving the efficiency and accuracy of image search has become more and more a hotpot in this research field. For different commercial image engines use different retrieval techniques respectively, the coverage area and accuracy of each individual search engine await development. An improved(More)
Since the Internet has become a huge repository of information, many studies address the issue of web pages categorization. For web page classification, we want to find a subset of words which help to discriminate between different kinds of web pages, so we introduced feature selection. In this paper, we study some feature selection methods such as ReliefF(More)
