Recent decades have witnessed growing interests in exploring the population genetics and phylogeography of crop plants and their wild relatives because of their important value as genetic resources. In this study, sequence variation of the nuclear Adh1a gene was used to investigate the genetic diversity and phylogeographic pattern of the wild and cultivated(More)
In the rice genus (Oryza), about one half of the species are allopolyploids. These species are not only important resources for rice breeding but also provide a unique opportunity for studying evolution of polyploid species. In the present study, we sequenced four biparentally inherited nuclear loci and three maternally inherited chloroplast fragments from(More)
UNLABELLED PREMISE OF THE STUDY We developed microsatellite primers to investigate genetic diversity and population genetic structure of the cosmopolitan submerged plant Myriophyllum spicatum. • METHODS AND RESULTS Twenty microsatellite loci were identified in M. spicatum using the microsatellite-enriched library method. The numbers of alleles per(More)
To provide high-quality duplicate chest images for the intensive care units, we have developed a digital duplication system in which film digitization is performed in conjunction with nonlinear density correction, contrast adjustment, and unsharp mask filtering. This system provides consistent image densities over a wide exposure range and enhancement of(More)
BACKGROUND The pathology of osteoarthritis (OA) is partly attributed to genetic factors; however, the role of ADAM12 polymorphism is still controversial. It is necessary to perform a meta-analysis to investigate this possible correlation. METHODS Case-control studies on the association between OA susceptibility and ADAM12 polymorphism were comprehensively(More)
OBJECTIVE To evaluate the risk factors of post-renal biopsy bleeding (PBB). METHODS We retrospectively analyzed the clinical data of 1 262 patients who received ultrasound-guided biopsy of native kidney at our hospital from January 2005 to December 2006. RESULTS The overall incidence of PBB was 30.3% (383/1,262), among which the incidence of hematoma(More)
PREMISE OF THE STUDY Comparative phylogeography of intercontinental disjunct taxa allowed us not only to elucidate their diversification and evolution following geographic isolation, but also to understand the effect of climatic and geological histories on the evolutionary processes of closely related species. A phylogeographic analysis was conducted on the(More)
