In order to clarify evolutionary patterns and processes of intraspecific diversification ofPedicularis chamissonis Steven, we analyzed intraspecific variation of the nucleotide sequences of non-coding regions of chloroplast DNA: the intergenic spacers betweentrnT (UGU) andtrnL (UAA) 5′exon,trnL (UAA) 3′exon andtrnF (GAA), andatpB andrbcL. In 24 populations(More)
Ledeb. (Primulaceae), we analyzed intraspecific variation of the nucleotide sequences of non-coding regions of chloroplast DNA: the intergenic spacers between trnT (UGU) and the trnL (UAA) 5′exon, the trnL (UAA) 3′exon and trnF (GAA), and atpB and rbcL. In 20 populations of P. cuneifolia, 22 nucleotide substitutions and five insertions/deletions were(More)
Interspecific hybridization is one of the major factors leading to phylogenetic incongruence among loci, but the knowledge is still limited about the potential of each locus to introgress between species. By directly sequencing three DNA regions: chloroplast DNAs (matK gene and trnL-F noncoding region), the nuclear ribosomal external transcribed spacer(More)
Molecular phylogeographic studies have revealed the genetic patterns and glacial-interglacial history of many plant and animal species. To infer the Quaternary history of alpine plants in the Japanese archipelago, which is poorly known, we investigated 203 individuals of Potentilla matsumurae and its varieties from 22 populations. We found 11 haplotypes(More)
Phylogeographic analyses using chloroplast DNA (cpDNA) variation were performed for Pedicularis ser. Gloriosae (Orobanchaceae). Eighty-one plants of 18 populations of 6 species (P. gloriosa, P. iwatensis, P. nipponica, P. ochiaiana, P. sceptrum-carolinum and P. grandiflora) were analyzed. Fifteen distinct haplotypes were identified based on six cpDNA(More)
BACKGROUND Quantitative assessment of left ventricular ejection fraction (LVEF) is technically difficult in patients with poor image quality (IQ). Mitral annulus velocity assessed by pulsed tissue Doppler imaging (TDI) and mitral annulus motion assessed by M-mode echocardiography has been shown to correlate with LVEF. Furthermore, mitral annulus sites are(More)
We have investigated cpDNA haplotype distribution in 24 populations of Fagus crenata in the southwest of Kanto District, Japan, and clarified the extent of intermixing of haplotypes in the contact zone by additional fine-scale analysis of two areas. Two cpDNA haplotypes belonging to different lineages were detected, and their distribution had geographical(More)
Insulin resistance (IR) is now considered to be a risk factor for coronary arterial atherosclerosis and is likely to be involved in a limited endothelium-dependent vasodilatory function in peripheral circulation. We investigated whether IR impairs endothelial vasodilator function in the noninfarcted coronary artery. In 14 nondiabetic patients (10 males, 66(More)
BACKGROUND Early defibrillation and cardiopulmonary bypass have been postulated to be a promising intervention against out-of-hospital cardiac arrest (OHCA); however, little is known about the long-term prognosis. The effects of early recovery of circulation (ROC) on neurological recovery and the long-term outcome in patients with OHCA were examined. (More)
Molecular phylogeography has inferred the history of differentiation between regions and/or among populations following the Pleistocene climatic oscillations, mostly based on the genetic structure of organelle DNA. However, such genetic structure only reflects the history of a single gene, and studies based on single-copy genes of nuclear DNA (nDNA) are(More)
