Despite an extensive diagnostic workup, some cases of acute transverse myelitis (ATM) remain of unknown etiology and have been referred to as "idiopathic" by the Transverse Myelitis Consortium group. In a retrospective study of 288 patients with ATM, 45 cases (15.6%) met the criteria for idiopathic ATM. The patients formed a relatively homogeneous group in terms of clinical and MRI data, but th...
Conventional ultrasound scanners can only display the blood velocity component parallel to the ultrasound beam. Introducing a laterally oscillating field gives signals from which the transverse velocity component can be estimated using 2:1 parallel receive beamformers. To yield the performance of the approach, this paper presents simulated and experimental results, obtained at a blood velocity ...

Background and Objective: Cesarean section is performed so frequently that even modest differences in outcome that result from a better technique can have effects on cost and public health. The purpose of this study was to compare two methods (transverse and cephalad) of expansion of the low transverse uterine incision in cesarean section. Materials and Methods: In this randomized clinic...
The variations of vertebral artery are important with regard to their potential clinical impact .The study reports the variation of course of right vertebral artery in male cadaver. The vertebral arteries arise from the superioposterior aspect of the first part of subclavian artery. The vessel takes a vertical course to enter into the transverse foramen of sixth cervical vertebra. Right vertebr...
This article investigates the static behavior of functionally graded plate under mechanical loads by using a new quasi 3D model. The theory is designated as fifth-order shear and normal deformation theory (FOSNDT). Properties of functionally graded material are graded across the transverse direction by using the rule of mixture i.e. power-law. The effect of thickness stretching is considered to...
We analyze stability of the TM polarized optical solitons and nonlinear guided waves localized at a metal-dielectric interface. We demonstrate, both analytically and numerically, that the spatial solitons can experience vectorial transverse modulational instability that leads to the generation of arrays of two-dimensional TM polarized self-trapped localized beams. In a sharp contrast, we reveal...
