Putaminal iron deposition is a histopathological feature of multiple system atrophy (MSA), which is not observed in patients with idiopathic Parkinson’s disease (PD). T2*-weighted magnetic resonance imaging (MRI) gradient echo (GE) sequences are sensitive for paramagnetic susceptibility changes and therefore may support the clinical differential diagnosis(More)
The evaluation of diagnostic agents or imaging procedures is governed by the same scientific and regulatory rules as that of other medical products. Receiver operating characteristic (ROC) curves, and especially the area under these ROC curves, are indices for the accuracy of a diagnostic test for continuous as well as ordinal data. The methodology of(More)
To determine the frequency and prognostic impact of isolated tumor cells (ITC) in regional lymph nodes judged to be tumor free in conventional histopathology among gastric cancer patients. Among 161 patients who underwent gastrectomy and D2-lymphadenectomy, 56 were staged pN0 (35%). Archival paraffin blocks of 1148 resected regional lymph nodes of those pN0(More)
The goal of the present study was to evaluate the partial surface replacement of the knee with stem cell-coated titanium implants and to provide a basis for a successful treatment of large osteochondral defects. Mesenchymal stem cells (MSCs) were isolated from bone marrow aspirates of adult sheep. Round titanium implants with a diameter of 2 x 7.3 mm were(More)
Campylobacter jejuni is a frequent cause of infectious diarrhoea and is increasingly recognized as a trigger for late-onset complications. The poor standardization of commonly used serological tests might explain the conflicting results regarding the frequency of antecedent C. jejuni infections in defined patient groups. In order to obtain reliable(More)
OBJECTIVE Pain of Achilles tendon (AT) is a common symptom in patients with severe familial hypercholesterolemia (FH) and often associated with AT xanthomas. It is unknown if these changes are potentially reversible during lipid lowering treatment. LDL-apheresis (LA) represents the most effective lipid lowering regimen. Aim of this investigation was to(More)
The goal of this study was to evaluate the performance of a computer-aided detection (CAD) system in full-field digital mammography (Senographe 2000D, General Electric, Buc, France) in finding out carcinomas depending on the parenchymal density. A total of 226 mediolateral oblique (MLO) and 186 craniocaudal (CC) mammographic views of histologically proven(More)
BACKGROUND The aim of the current study was to investigate a putative relationship between (i) growth characteristics (proliferation and tumorigenicity) of nine glioblastoma multiforme (GBM) cell lines under different growth-stimulating conditions in vitro and (ii) their basal expression of a panel of growth factor receptors/autocrine cytokines. MATERIALS(More)
The object of this study was to determine the performance of a computer-aided detection system in full-field digital mammography (Senographe 2000D, General Electric, Buc, France) in detecting carcinomas in breasts in dependence of the initial Breast Imaging Reporting and Data System (BI-RADS) categories. A total of 226 mediolateral oblique (MLO) and 186(More)
Objective. A study supported by the EULAR and the ACR being conducted to establish classification criteria for polymyalgia rheumatica (PMR) will include ultrasound examination of the shoulders and hips. Ultrasound (US) depicts glenohumeral joint effusion, biceps tenosynovitis, subdeltoid bursitis, hip joint synovitis, and trochanteric bursitis in PMR. These(More)
