Mesenchymal progenitor or stem cells (MPCs) isolated from fetal blood, liver, and bone marrow are a population of multipotential cells that can proliferate and differentiate into multiple mesodermal tissues including bone, cartilage, muscle, ligament, tendon, fat, and stroma. The objective of this study was to isolate and characterize MPCs in the human(More)
While pleural effusion in multiple myeloma is relatively infrequent, myelomatous pleural effusion is extremely rare. We experienced a 61-year-old woman with IgD-lambda multiple myeloma and pleural effusion. The diagnosis was made originally by pleural biopsy, pleural fluid cytology and immunoelectropheresis of pleural fluid. Transient improvement of the(More)
Crickets are able to sense their surrounding environment through about 2000 filiform hairs located on a pair of abdominal cerci. The mechanism by which the cricket is able to sense a wide range of input signals using these filiform hairs of different length and orientation is of great interest. Most of the previous filiform hair models have focused on a(More)
Medulloblastoma accounts for 20 to 25% of all intracranial neoplasms in children. The significance of the presence of isochromosome 17q (i(17q)), proliferative potential, apoptotic activity, and expression of c-erbB-2, bd-2, and p53 proteins in predicting long-term survival of patients with medulloblastomas was investigated. Twenty children were divided(More)
We investigate the tracheal compression by aortic arch in patients with congenitally corrected transposition of the great arteries. Fourteen patients whose ascending aorta was connected to descending aorta on the contralateral side were divided into two groups according to the severity of tracheal compression on lateral angiogram: group 1 (stenosis ? 50%,(More)
Increased oxidative stress in vascular smooth muscle cells (VSMCs) has been implicated in the pathogenesis of accelerated atherosclerosis in patients with diabetes mellitus. Uncoupling protein 2 (UCP-2) is an important regulator of intracellular reactive oxygen species (ROS) production. We hypothesised that UCP-2 functions as an inhibitor of the(More)
Choroid plexus carcinoma is a rare intracranial neoplasm, affecting mainly very young children. The commonest site is within the lateral ventricles and the prognosis is very poor. We report a seven month old baby boy who presented with raised intracranial pressure and seizures. Brain CT scan showed large intraventricular mass with calcification and(More)
Introduction: The detection of tissue borders is of great importance in several MRI applications. Edge detection is typically performed as a post-processing step, using magnitude images that are reconstructed from fully-sampled k-space data. In dynamic imaging (e.g. of human speech, ventricular function, and joint kinematics), tissue borders often comprise(More)
We present frequencies of fetal chromosomal abnormalities in 4,907 prenatal cytogenetic examinations at Samsung Cheil Hospital from 1988 to 1997 for 10 yr duration. Prenatal karyotypes were undertaken in 3,913 amniotic fluid samples, 800 chorionic villi samples, and 194 percutaneous umbilical blood samples. The frequency of fetal abnormal karyotypes was(More)
Introduction: 3D MR imaging of the vocal tract during sustained sound production provides valuable insight into the shaping and modeling of vocal articulation [1]. Recently, high spatial resolution 3D imaging of vocal tract shaping (with no repetitions of the same sound) was demonstrated [2] by utilizing compressed sensing MRI [3] with a single channel(More)
