AIM To externally validate a computer-assisted detection (CAD) system for computed tomography (CT) colonography, using data from a single centre uninvolved with the software development. MATERIALS AND METHODS Twenty-five multi-detector CT colonography examinations of patients with validated polyps accumulated at a single centre were examined by two(More)
Current antagonists for the parathyroid hormone (PTH)/PTH-related protein (PTHrP) receptor (PTHR) are N-terminally truncated or N-terminally modified analogs of PTH(1-34) or PTHrP(1-34) and are thought to bind predominantly to the N-terminal extracellular (N) domain of the receptor. We hypothesized that ligands that bind only to PTHR region comprised of the(More)
Recent data suggest that the binding of parathyroid hormone (PTH)-(1-34) to the PTH-1 receptor (P1R) involves a high-affinity interaction between the C-terminal (15-34) domain of the ligand and the amino-terminal extracellular (N) domain of the receptor and a low-affinity interaction between the N-terminal (1-14) portion of PTH and the juxtamembrane (J)(More)
INTRODUCTION Despite advances in surgical and anaesthetic techniques the mortality after hip fracture has not significantly changed in the last 40 years. Pre-operative anaemia is a risk factor for peri-operative death. We speculate that a significant proportion of the blood loss related to hip fractures has occurred prior to surgery. Identifying patients at(More)
Recent functional studies have suggested that position 19 in PTH interacts with the portion of the PTH-1 receptor (P1R) that contains the extracellular loops and seven transmembrance helices (TMs) (the J domain). We tested this hypothesis using the photoaffinity cross-linking approach. A PTHrP(1-36) analog and a conformationally constrained PTH(1-21)(More)
BACKGROUND Diagnostic approach to chest pain in women is challenging, but still under-investigated. The purpose of this study was to assess the diagnostic performance of 64-slice multidetector coronary computed tomographic angiography (CCTA) in women with chest pain. METHODS AND RESULTS We included 606 patients--255 women and 351 men (mean age 61 ± 12(More)
BACKGROUND The diagnosis of coronary artery disease (CAD) in women remains a challenge, given their lower prevalence of obstructive disease and the suboptimal performance of traditional noninvasive tests (exercise electrocardiography and stress myocardial perfusion imaging). Coronary computed tomographic angiography (CTA) is a validated method for detection(More)
With reference sera and homozygous typing cells (HTCs) of 3rd Asia-Oceania Histocompatibility Workshop Conference, 56 healthy unrelated subjects in Shanghai were typed for HLA-A, B, C, DR, DQ, and Dw. This paper presents the results of HLA-Dw typing, its relationship to serological class II antigens, and the distribution of Dw in the population. The(More)
