Feasibility of coronary angiography (CAG) and percutaneous intervention (PCI) via left snuffbox approach is still concerned. We aimed to investigate efficacy safety the for CAG PCI.Left was tried in 150 patients who planned perform or PCI suspected myocardial ischemia between 1 November 2017 31 March 2018.Success rate radial artery (RA) cannulation 88.0% (n=132). Among 132 individuals, 58 (43.9%) acute syndrome (ACS) were included. The diameter RA significantly smaller than conventional...
The effects of terrestrial habitat islands on gene flow and genetic diversity in animal populations have been predicted discussed theoretical terms, but empirical data are needed to test these predictions provide an understanding the relationships life‐history characteristics genetics insular species. We studied saxicolous mice ( Phyllotis xanthopygus ) Patagonia explore structure, phylogeography, a species inhabiting natural islands. Phylogeographic analyses based mtDNA sequences revealed...
DNA sequences from mitochondrial tRNA genes, the light strand replication site, and a region of 12S rRNA gene were used to test hypothesis that unusual Antillean island subspecies, Artibeus jamaicensis schwartzi, was derived South American origin. Parsimony bootstraping analyses allied genome in these bats with (mtDNA) isolated planirostris living French Guiana rather than mtDNA Antilles or Mexico. Although differed slightly, identical A. j. schwartzi on St. Vincent Guiana. It is proposed an...
In patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD), the optimal timing of staged percutaneous coronary intervention (PCI) remains unclear. This study was a retrospective analysis 753 STEMI MVD who were treated by PCI in Convergent Registry Catholic Chonnam University for Acute (MI). Patients divided into 3 groups according to time from initial PCI: group 1 (n=316, performed during index procedure), 2 (n=360, within week), (n=77, after week). The...
Chest pain is an essential symptom in the diagnosis of acute coronary syndrome (ACS). One-third patients with ACS present atypically, which can influence their receiving timely lifesaving therapy.A total 617 NSTEMI from Korea Acute MI Registry (KAMIR) and Working Group on (KorMI) databases were analyzed. The study population was divided into two groups by symptoms at presentation (typical group, 128; atypical groups, 128).In this population, 23% presented without chest pain. After propensity...
The Japanese oak silkmoth, Antheraea yamamai Guérin-Méneville, 1861 (Lepidoptera: Saturniidae), is an important natural resource of industrial value for silk fiber production. Owing to a lack geographic and population genetic information, systematic domestication An. has not been possible yet. In this study, 10 microsatellite markers developed using next-generation sequencing two mitochondrial DNA (mtDNA) gene sequences (COI ND4) were used investigate the variation structure populations in...
Background: The current screening strategy for subclinical coronary atherosclerosis in asymptomatic diabetic patients is not sufficient real clinical practice. A new was investigated that uses cardiac multi-detector computed tomography (MDCT) and a treadmill test (TMT). Methods Results: total of 445 self-referred underwent MDCT. treatment plan determined according to the MDCT TMT. All follow-up events were investigated. incidence 49.4%. group without plaque did experience any 675.1...
The population genetics of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), was characterized using maternally inherited mitochondrial A+Trich region and bi-parentally nuclear internal transcribed spacer 2 (ITS2).One hundred eighty-seven specimens roller collected from 13 Korean Chinese localities revealed 94 A+T-rich haplotypes, ranging in sequence length 339 to 348 bp 129 ITS2 types, 444 450 bp, with maximum divergences 4.55 4.43%, respectively.The finding...
Large-scale wind power may change and vary the load flows in a system. Thus, it also has an impact on transmission losses. The traditionally used simulation cases not be representative for analyzing overall This paper suggests screening method determining to analysis of system approach is based estimated data series production scenarios. losses end are by flow simulations. suggested demonstrated illustrated integration study Kazakhstan. results case indicate decrease Kazakhstan according...
