STUDY DESIGN Retrospective cross-sectional study. OBJECTIVE Determine if pre-operative cervical alignment serves as an independent predictor of pre-operative disability as measured by the neck disability index (NDI). SUMMARY OF BACKGROUND DATA There is growing interest in the relationship between cervical sagittal alignment and clinical outcomes. While prior studies have shown that C2-C7 sa...

One of the key issues associated with the utilization of block copolymer (BCP) thin films in nanoscience and nanotechnology is control of their alignment and orientation over macroscopic dimensions. We have recently reported a method, solvent vapor annealing with soft shear (SVA-SS), for fabricating unidirectional alignment of cylindrical nanostructures. This method is a simple extension of the...

STUDY DESIGN Retrospective case series. OBJECTIVE To evaluate if spine measurement software can simulate sagittal alignment following pedicle subtraction osteotomy (PSO). METHODS We retrospectively reviewed consecutive adult spinal deformity patients who underwent lumbar PSO. Sagittal measurements were performed on preoperative lateral, standing radiographs. Sagittal measurements after simu...

STUDY DESIGN Prospective physical measurement of the sagittal vertical axis (SVA). PURPOSE To evaluate a simple method for measuring SVA by analyzing its relationship with radiographic measurements and clinical appearance. OVERVIEW OF LITERATURE No studies have examined physical measurements using the cranial center of gravity (CCG) in a relaxed standing position. METHODS The physical mea...

The attitude towards computer-related tasks, computer anxiety, and spatial visualization ability (SVA) of a group of first-year computer science students were measured just before their study commenced. The results were analyzed empirically based on two independent variables, i.e., culture and computer experience. It was found that African and European users generally have the same attitude tow...

We analyzed a shell vial culture assay (SVA), real-time PCR, and a direct fluorescent antibody assay (DFA) for rapid detection of vaccinia virus from vaccination sites of Dryvax vaccine recipients. Of 47 samples assayed, 100% were positive by PCR, 89% were positive by SVA, and 40% were positive by DFA. DFA was limited by the need for adequate numbers of cells, with 32% of samples inadequate for...

Formation of an acyl-CoA thioester has been proposed, but not directly demonstrated, to be a key step in mediating both lactonization and atypical beta-oxidation of 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors. Here, we describe studies to characterize formation of acyl-CoA thioesters in vitro in mouse liver preparations using the hydroxy acid form of simvastatin (SVA) as a model substra...

Combination of ruptured sinus of Valsalva aneurysm (SVA), and a coexisting asymptomatic adult aortic isthmic coarctation is extremely rare. The timing and sequence of surgical and/or interventional repair of these two pathologies are controversial. We present a case of a 37-year-old male who was admitted to our department because of severe acute congestive heart failure and signs of ruptured an...

Introduction. Unruptured sinus of valsalva aneurysm (SVA) is a rare congenital anomaly, particularly, when it coexists with a ventricular septal defect (VSD) and aortic regurgitation due to the prolapse of the elongated aortic cusp into the VSD. In this report, we present the case of a 19-year-old young man with VSD challenging in spite of dyspnea and lower limb edema. Presentation of Case. Its...

Fig. 1. (A) CT scan image. CT scan shows giant non-coronary sinus of Valsalva aneurysm with neighbouring structures. Arrows indicate closed aortic valves. Ao: aorta, NC-SVA: non-coronary sinus of Valsalva aneurysm, LV: left ventricle, PA: pulmonary artery. (B) TEE image. Trans-oesophageal echocardiography shows aortic cusps level image of sinus of Valsalva aneurysm. *Arrows show aortic cusps, *...
