UNLABELLED A lack of standardized evaluation procedures for dopamine transporter (DAT) SPECT investigations impairs both intra- and interindividual comparisons as well as multicenter trials-for example, for assessment of disease progression or the response to various drug treatments. Therefore, the aim of this study was to evaluate a novel automated method,(More)
Diabetes mellitus adversely affects the skeleton and is associated with an increased risk of osteoporosis and fragility fractures. The mechanisms underlying low bone strength are not fully understood but could include impaired accrual of peak bone mass and diabetic complications, such as nephropathy. Type 1 diabetes mellitus (T1DM) affects the skeleton more(More)
Sclerostin is predominantly expressed by osteocytes. Serum sclerostin levels are positively correlated with areal bone mineral density (aBMD) measured by dual-energy X-ray absorptiometry (DXA) and bone microarchitecture assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT) in small studies. We assessed the relation of serum(More)
PURPOSE Metal ion release by orthopaedic implants may cause local and systemic effects and induce hypersensitivity reactions. Coated implants have been developed to prevent or reduce these effects. This study was initiated to investigate the safety of a novel coating for total knee arthroplasty (TKA) implants. METHODS A total of 120 patients undergoing(More)
AIM Type 1 diabetes mellitus (T1DM) increases fragility fractures due to low bone mass, micro-architectural alterations and decreased bone formation. Sclerostin is expressed by osteocytes and inhibits osteoblastic bone formation. We evaluated serum sclerostin levels in T1DM and their association with bone mineral density (BMD), bone turnover, glycaemic(More)
Secondary osteoporosis is characterized by low bone mass with microarchitectural alterations in bone leading to fragility fractures in the presence of an underlying disease or medication. Scenarios that are highly suspicious for secondary osteoporosis include fragility fractures in younger men or premenopausal women, very low bone mineral density (BMD)(More)
Type 2 diabetes mellitus (T2DM) is associated with increased skeletal fragility and impaired fracture healing. Intermittent PTH therapy increases bone strength; however, its skeletal and metabolic effects in diabetes are unclear. We assessed whether PTH improves skeletal and metabolic function in rats with T2DM. Subcritical femoral defects were created in(More)
PURPOSE We hypothesized that combining pre- and postsynaptic quantitative information about the dopaminergic system would provide a higher diagnostic accuracy in the differential diagnosis of parkinsonism than specific striatal D(2) receptor binding alone. Therefore, the aim of the study was to introduce new semi-quantitative parameters and evaluate their(More)
Type 2 diabetes mellitus results in increased risk of fracture and delayed fracture healing. ZDF fa/fa rats are an established model of type 2 diabetes mellitus with low bone mass and delayed bone healing. We tested whether a sclerostin-neutralizing antibody (Scl-AbVI) would reverse the skeletal deficits of diabetic ZDF rats. Femoral defects of 3 mm were(More)
Thermal trauma has a direct effect on mast cells, triggering the secretion of histamine. This secretion leads to an enhanced xanthine oxidase activity and an increased production of reactive oxygen species (ROS), the latter being produced after burns through differing mechanisms. As ROS have been shown to have deleterious effects on cellular membranes, a(More)
