Background The aim of this study was the ex vivo expansion of Umbilical Cord Blood hematopoietic stem cells on biocompatible nanofiber scaffolds. Materials and Methods CD133+ hematopoietic stem cells were separated from umbilical cord blood using MidiMacs (positive selection) system by means of monocolonal antibody CD133 (microbeads) subsequently, flowcytometry method was done to asses...

This article is intended to provide an overview of various aspects of clinical PET/CT. These include discussions of: (i) Important areas of clinical application; (ii) Opportunities in clinical research; (iii) Scanner and operating-mode considerations (e.g. BGO vs. LSO, LYSO or GSO scanners, 2D vs. 3D imaging). (iv) Study-specific considerations (e.g. patient preparation and positioning is...

patients and methods in 382 subjects admitted in the emergency department (ed), we evaluated maximal (volmax) and minimal (volmin) la volumes and la emptying fraction (la-ef), from rt-3d images, with a semiautomated border detection program. a follow-up was performed in order to evaluate all-cause mortality and new hospital admission for cardiovascular events. objectives aims of this study were...

BACKGROUND/OBJECTIVE Judgement of nasolabial aesthetics in cleft lip and palate (CLP) is a vital component of assessment of treatment outcome. It is usually performed based on two-dimensional (2D) facial photographs. An increasing use of three-dimensional (3D) imaging warrants an assessment if 3D images can substitute 2D photographs during aesthetic evaluation. The aim of this study was to comp...

The objectives of this study are mainly two: (1) to validate whether a single grain scratch process can be modeled in two dimensions under the assumption plane strain, and (2) select best discretization approach model process. This paper first focuses on simulation orthogonal cutting (aluminum alloy A2024 T351) using mesh-based approaches, pure Lagrangian method (LAG) arbitrary Lagrangian–Euler...

adenomyosis is an idiopathic and benign disease in which ectopic endometrial glands embedded deeply in myometrial smooth muscle with the compensatory hypertrophy of the myometrium surrounding the ectopic endometrium (1, 2). there is a correlation between depth of the infiltration and initial too high stage of adenomyosis. lesions may characterize as a diffuse or focal lesions. the highest preva...

conclusions we recommend the additional 2d-fluoroscopic tangential view for detection of screw misplacements caused by overlength, with penetration on the dorsal cortical surface of the distal radius, predominantly observed for the most lateral screw position. the use of intraoperative 3d fluoroscopy did not become accepted in our clinical routine, due to the technical demanding and time consum...
