right bundle branch block (rbbb) is considered as an important predictor of poor outcome in patients with acute myocardial infarction, but the prognostic implication of rbbb in patients with suspected coronary artery disease (cad) is unclear. furthermore, the association between rbbb and incidence of cad also its influence on the severity of stenosis in coronary arteries has not been establishe...

in this paper, it was shown that , where  and , and , where  is not prime and , are od-characterizable.

let $g$ be a connected graph with vertex set $v(g)$‎. ‎the‎ ‎degree resistance distance of $g$ is defined as $d_r(g) = sum_{{u‎,‎v} subseteq v(g)} [d(u)+d(v)] r(u,v)$‎, ‎where $d(u)$ is the degree‎ ‎of vertex $u$‎, ‎and $r(u,v)$ denotes the resistance distance between‎ ‎$u$ and $v$‎. ‎in this paper‎, ‎we characterize $n$-vertex unicyclic‎ ‎graphs having minimum and second minimum degree resista...

Purpose To evaluate the degree of psychological distress in symptomatic vitreous floater patients and to evaluate whether these psychological factors are associated with the severity of discomfort associated with vitreous floaters. Methods We recruited 61 patients with symptomatic vitreous floaters and 34 controls. The degree of posterior vitreous detachment (PVD) was evaluated using optical ...

BACKGROUND Eosinophilia is well recognized in specific conditions. The objective of the present study was to determine clinico-radiologic characteristics of eosinophilia and changes in prevalence over 10 years in recipients of private health screening program at a tertiary hospital in Korea. METHODS Data of private health screening program recipients at the health promotion center of Chung-An...

BACKGROUND The relationship between reduced glucose metabolism in positron emission tomography with fludeoxyglucose F 18 ([(18)F]FDG-PET) and hippocampal damage (HD) in patients with temporal lobe epilepsy is still unclear. OBJECTIVE To determine whether the presence and severity of HD verified by quantitative magnetic resonance imaging (QMRI) and histopathological analysis affect the degree ...

BACKGROUND AND PURPOSE Little is known about the risk factors of dilated Virchow-Robin spaces (dVRS) and their relation with other markers of brain small vessel disease. We investigated both issues in a large population-based sample of elderly individuals. METHODS Severity of dVRS was semiquantitatively graded in both white matter and basal ganglia using high-resolution 3-dimensional MRI imag...

OBJECTIVES This study examined: 1) the impact of myectomy on postoperative mitral regurgitation (MR) and 2) the association between the severity of MR and the left ventricular outflow tract (LVOT) gradient. BACKGROUND For patients with hypertrophic obstructive cardiomyopathy (HOCM) and MR, controversy exists as to whether myectomy alone is sufficient in eliminating MR. Furthermore, the relati...

PURPOSE To determine whether there is a correlation among mutations in the cytochrome P450 1B1 gene (CYP1B1), the degree of angle dysgenesis observed histologically, and disease severity in congenital glaucoma. METHODS Direct DNA sequencing was utilized to screen six unrelated children with congenital glaucoma, each set of parents, and all siblings for CYP1B1 mutations. Specimens of the anter...
