Langerhans cell histiocytosis syndromes have been described as encompassing a range of disorders, such as eosinophilic granuloma, Letterer-Siwe syndrome and Hand-Schüller-Christian disease. These disorders have been mainly diagnosed at early ages of life and are relatively rare entities in adult age groups. In this study, we aimed to retrospectively evaluate the patients with Langerhans cell hi...

gone placement of multiple uncovered biliary metal stents (Wallstent; Boston Scientific, Natick, Massachusetts, USA) over the previous 10 years for an indeterminate distal common bile duct (CBD) stricture was referred to us for an attempt at removal of the stents. She had recently been undergoing monthly sessions of endoscopic retrograde cholangiopancreatography (ERCP) to clean the stents as tr...

Extracellular, intracellular or surface proteins can be used as putative markers to characterize human mesenchymal stem cells (hMSC). However, these markers are also expressed by other cell types and primary cell pools reveal considerable heterogeneity. Therefore, the simultaneous detection of several markers on a single cell appears to be an attractive approach to identify hMSC. Here we demons...

Introduction: Multilevel converters are finding considerable attention in academia and industry as one of the preferred choices for high power conversion applications, such as traction drives, active filters, reactive power compensators, photovoltaic power conversion, uninterruptible power supplies, static compensators and flexible AC transmission systems. In general, multilevel converters are ...

BACKGROUND We aimed to present the demographic and epidemiologic data on spinal cord injury (SCI) patients who were rehabilitated at our hospital, to identify high-risk groups and etiological factors, and to evaluate the factors that affect the duration of hospitalization (DOH). METHODS Data on 905 SCI patients treated on an inpatient basis between December 2000 and June 2007 at our hospital ...

this paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of iranian standard 2800. seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. these models cover a wide range of very torsional...

Third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (Goetz technique). Primary healing occurred in all of them without any complication. The conception rate obtained after surgery was 70.1%. Five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. Three mares have produced several healthy foals without any ...
