AIM:To compare the changes in excyclotorsion after inferior oblique(IO)recession in patients with primary and secondary inferior oblique overaction(IOOA).METHODS:We retrospectively analyzed the data obtained from patients with IOOA who underwent graded IO *** patients were followed up for at least 3 mo after *** photographs were taken preand postoperatively,and the sum of the angles of torsion in both eyes was used to analyze changes in *** were divided into two groups:those diagnosed with primary IOOA were enrolled in the 1’IOOA group,and those diagnosed with secondary IOOA caused by superior oblique palsy(SOP)were enrolled in the 2’IOOA *** before and after surgery were compared between the two ***:A total of 78 patients were enrolled in this study:34 eyes in the 1’IOOA group and 44 eyes in the 2’IOOA *** the 78 patients,torsional angle significantly decreased from 15.31°±7.40°to 12.11°±6.53°after IO recession(P<0.001).Mean preoperative torsional angle was larger in the 2’IOOA group than in the 1’IOOA group(P=0.03).In both groups,excyclotorsion significantly decreased after IO recession(P=0.001 and P<0.001,respectively);however,there was no significant difference in the amounts of changes in excyclotorsion between the two ***:Excyclotorsion is significantly larger in secondary IOOA than in primary IOOA,and a significant decrease in the torsional angle occurs after IO recession in both types of IOOA.

Room temperature deformation behavior of A1-8Fe-2Mo-2V-1Zr alloy produced by spray forming and subsequent warm-extrusion at 693 K and/or rolling at 423 K was investigated in terms of tensile test and microstructural *** the specimen processed by spray forming and warm extrusion, the microstructure consisting of equiaxed grains with the average grain size of 500 nm in the matrix phase and uniformly dispersed fine intermetallic A13(Fe, Mo, V, Zr) and A16(Fe, Mo, V, Zr) phases less than 100 nm was characterized. It was revealed that subsequent warm rolling after warm extrusion promotes precipitation of a fine dispersoid from the supersaturated matrix phase. Warm rolling was found to be effective to increase the yield and tensile strength in the high strain rate regime. Elongation of the warm rolled specimen showed highe r value than extruded specimen over the whole strain rate region studied.

Micromorphology and Ultrastructure of the Foot of the Equilateral Venus <i>Gomphina veneriformis</i>(Bivalvia: Veneridae)

引用

CellBio 2012年第1期1卷 11-16页

作者： Jung Jun Park Jung Sick Lee Yeon Gyu Lee jae won kim Aquaculture Management Division NFRDI Busan Korea Department of Aqualife Medicine Chonnam National University Yeosu Korea Department of Marine Life-Science Gangwon Provincial College Gangneung Korea Faculty of Marine Technology Chonnam National University Yeosu Korea

The shape and microscopic structure of the foot of the equilateral Venus, Gomphina veneriformis are described by light and electron microscopy along with the substrate conditions of their habitat. The habitat sediment of G. veneriformis is composed of sand (2 - 0.063 mm in diameter), mainly. The foot is wedge-shaped with multiple vertical furrows on the surface. Although the foot is composed of an epithelial layer, a connective tissue layer and a muscular layer, the boundary between the connective tissue and muscular layer is not clear. The epithelial layer was composed mostly of ciliated columnar epithelia and secretory cells. Epithelial cells forming the apical region of the fold were long columnar, while cells of the interfold were mostly short columnar. The cilia and microvilli were commonly observed on the free surface of epithelial cells, while tight junctions of apico-lateral aspect and membrane interdigitations were found between the epithelial cells. Secretory cells were found to contain acidic mucopolysaccharide, and were classified into two types in accordance with the shapes and ultrastructures of secretory granules. The muscle fibers were composed of thin and thick microfilaments, the proportions of which were 81.3% and 18.7%, respectively. It was determined that such morphology and structural characteristics of the foot of G. veneriformis would present advantageous conditions for borrowing into substrate and mobility.

Computed tomography coronary angiography after excluding myocardial infarction:high-sensitivity troponin versus risk score-guided approach

作者： won jae Yoo Shin Ahn Bora Chae won Young kim Department of Emergency Medicine Asan Medical CenterUniversity of Ulsan College of MedicineSeoul 05505Republicof Korea

BACKGROUND:Patients with suspected acute coronary syndrome (ACS) in whom myocardial infarction has been ruled out are still at risk of having obstructive coronary artery disease (CAD).This rate is higher among patients with intermediate high-sensitivity troponin I (hsTnI) concentrations (5 ng/L to 99th percentile) than low concentrations (<5 ng/L).Therefore,an intermediate concentration has been suggested as a candidate for downstream investigation with computed tomography coronary angiography(CTCA).We tried to compare the HEART score-guided ***-guided approach for identifying obstructive ***:From a prospective cohort study of patients presenting to the emergency department with suspected ACS,433 patients without elevated hsTnI who also underwent CTCA were selected and *** performances of hsTnI concentration and HEART score were compared using sensitivity,specificity,positive predictive value (PPV),and negative predictive value (NPV).RESULTS:Overall,120 (27.7%) patients had obstructive *** with intermediate hsTnI concentrations were more likely to have obstructive CAD than those with low hsTnI concentrations(40.0%vs.18.1%);patients with non-low-risk HEART scores (≥4 points) were also more likely to have obstructive CAD than those with low-risk scores (0 to 3 points)(41.0%vs.7.6%).The HEART score had higher sensitivity and NPV for detecting obstructive CAD in each classification than hsTnI concentration (sensitivity:89.2%vs.63.3%;NPV:92.4%vs.81.9%,respectively).CONCLUSION:After excluding myocardial infarction in patients with suspected ACS,adding the HEART score for selecting candidates for CTCA could improve patient risk stratification more accurately than relying on hsTnI concentration.

As the increasing number of Phasor Measurement Units(PMUs) are deployed, wide area protection in power systems has been gaining interest. In particular, fault detection, fault classification and fault area estimation are essential to reduce the damage of faults, and even prevent catastrophic cascades of failures. In this paper, we present a scheme for fault area estimation using PMUs and traveling wave theory. The purpose of this paper is to formulate a scheme for fault area estimation by calculating the approximate fault location based on traveling wave *** research has targeted at reliable operation of wide transmission system through the estimation of fault *** verify the suggested scheme, the various simulations are performed in practical Korean power transmission *** simulation results show that the proposed scheme has a good performance with high accuracy for estimating fault area.
