For interpretation of quantitative gene expression measurements in clinical tumor samples, a normalizer is necessary to correct expression data for differences in cellular input, RNA quality, and RT efficiency between samples. In many studies, a single housekeeping gene is used for normalization. However, no unequivocal single reference gene (with proven(More)
PURPOSE To retrospectively compare transition zone (TZ) cancer detection and localization accuracy of 3-T T2-weighted magnetic resonance (MR) imaging with that of multiparametric (MP) MR imaging, with radical prostatectomy specimens as the reference standard. MATERIALS AND METHODS The informed consent requirement was waived by the institutional review(More)
Microdeletions and microduplications, not visible by routine chromosome analysis, are a major cause of human malformation and mental retardation. Novel high-resolution, whole-genome technologies can improve the diagnostic detection rate of these small chromosomal abnormalities. Array-based comparative genomic hybridization allows such a high-resolution(More)
Single nucleotide polymorphisms (SNPs) in the NOD2 gene have significant impact on both treatment-related mortality (TRM) and acute GVHD (aGVHD) in haematopoietic stem cell transplantation (HSCT). The effect of these polymorphisms when using T-cell-depleted grafts has been poorly studied. We retrospectively analysed NOD2 polymorphisms in a cohort of 85(More)
OBJECTIVE To investigate the number of subsidences of inserted cervical carbon fiber cages and to define predictive factors for subsidence. METHODS All patients treated for a cervical herniated disc and fusion with a cervical carbon fiber cage between January 2002 and December 2003 were retrospectively identified. The radiological examinations were(More)
Mental retardation (MR) occurs in 2%-3% of the general population. Conventional karyotyping has a resolution of 5-10 million bases and detects chromosomal alterations in approximately 5% of individuals with unexplained MR. The frequency of smaller submicroscopic chromosomal alterations in these patients is unknown. Novel molecular karyotyping methods, such(More)
BACKGROUND The accurate evaluation of intrinsic myocardial contractility in children with or without congenital heart disease (CHD) has turned out to be a challenge. Two-dimensional strain echocardiographic (2DSTE) imaging or two-dimensional speckle-tracking echocardiographic imaging appears to hold significant promise as a tool to improve the assessment of(More)
Since only 20% of female fragile X premutation carriers develop premature ovarian failure (POF, i.e., amenorrhea before age of 40 years), and since X chromosome inactivation (XCI) determines the phenotypic severity of full mutation women, we reasoned that the development of POF in fragile X premutation carriers could be due to skewed XCI (XCI ratio >80:20).(More)
BACKGROUND Anthracycline-induced cardiotoxicity can cause serious health problems for an increasing number of survivors of childhood malignancies. The aims of this study were to document plasma concentrations of cardiac troponin T (cTnT) and NT-pro-brain natriuretic peptide (NT-pro-BNP) in a large group of asymptomatic long-term survivors of childhood(More)
BACKGROUND The 2 most frequently used endoscopic methods to treat Zenker's diverticulum are staple-assisted and CO(2) laser esophagodiverticulostomy. METHODS The study centered around a retrospective evaluation of 107 patients with Zenker's diverticulum who were treated endoscopically by CO(2) laser (n = 72) or staple-assisted diverticulostomy (n = 35).(More)
