This study has identified a single amino acid change in the viral glycoprotein that profoundly affects the ability of lymphocytic choriomeningitis virus (LCMV) to persist in its natural host. Adult immunocompetent mice infected with a variant of the Armstrong strain, spleen isolate clone 13 (svA/svA), harbor virus for several months and exhibit suppressed T cell responses. In contrast, adult mi...

Sinus of Valsalva aneurysm (SVA) is an uncommon anomaly of the aorta. Rupture of SVA often precipitates dramatic clinical complications, including heart failures. Right SVAs are the most common type, and when they rupture, they usually rupture into the right ventricle or right atrium. Rupture into left ventricle or interventricular septum is rare. Herein, we report a case of right SVA rupture w...

Cardiac magnetic resonance imaging (CMR) demonstrated a sinus of Valsalva aneurysm (SVA) with severe dilatation of the right coronary sinus in association with a congenital bicuspid aortic valve (BAV) and sub-aortic membrane. The SVA had not been apparent on echocardiography as the dilatation was outside standard echo image planes. On both CMR and echo, blood flow was eccentrically directed int...

Information seeking skills are becoming increasingly important as rapid and widespread developments in technology have made information available in more formats and from more sources than ever before. Research in human computer interaction (HCI) has demonstrated that primary cognitive abilities represent a powerful predictor of information-seeking success in electronic information systems. Spe...

SystemVerilog Assertions (SVA) can be used to implement relatively complex functional coverage models under appropriate circumstances. This paper explores the issues and implementation of such a functional coverage model to demonstrate both the capabilities of SVA coverage and illustrate coding techniques which can also be applied to the more typical use of SVA coverage, which is to specify key...

BACKGROUND The sinus of Valsalva aneurysm (SVA) is a small dilatation caused by a separation between the aortic media and annulus fibrosus. Its origin may be either acquired or congenital. The right coronary sinus is most frequently affected, with the most common complication being rupture. CLINICAL CASES We report two cases of SVA complicated with rupture to the right cavities with severe ca...

BACKGROUND The aim of this study was to identify the predictors of deterioration in sagittal balance in patients with adult scoliosis following long fusion arthrodesis to L5. MATERIAL AND METHODS A retrospective clinical study included 63 patients with adult scoliosis who underwent long fusion arthrodesis to L5, between February 2005 and May 2015. Radiological imaging values included the angle ...

We propose a Stereoscopic Visual Attention(SVA-) based regional bit allocation optimization forMultiview Video Coding (MVC) by the exploiting visual redundancies from human perceptions. We propose a novel SVAmodel, where multiple perceptual stimuli including depth, motion, intensity, color, and orientation contrast are utilized, to simulate the visual attention mechanisms of human visual system...

PURPOSE Anterior cervical discectomy and fusion (ACDF) has become a common spine procedure, however, there have been no previous studies on whole spine alignment changes after cervical fusion. Our purpose in this study was to determine whole spine sagittal alignment and pelvic alignment changes after ACDF. MATERIALS AND METHODS Forty-eight patients who had undergone ACDF from January 2011 to ...

BACKGROUND We reviewed the experience of An Zhen and Fu Wai Hospital for congenital sinus of Valsalva aneurysm (SVA) to determine risk factors for aortic valve replacement (AVR) and postoperative progression of aortic regurgitation (AR). METHODS Over a 7-year period, 255 patients underwent surgical repair of an SVA. Aneurysms originated from the right sinus and the noncoronary sinus in 212 pa...
