The activities of glutathione peroxidase (GSH-px), glutathione reductase (GSSG-rx) and glutathione transferase (GST) were measured in myocardial specimens obtained from right atria of patients subjected to different period of ischaemic arrest (aortic clamping ranging from 10 min to 90 min) followed by 60 min. of reperfusion, during open heart surgery 41-90(More)
It is well-known the central role of inflammation in the inhibition of erythropoiesis and iron availability in chronic kidney disease (CKD) patients with erythropoietin (EPO)-resistant anaemia. This inflammatory action is mediated by suppressive cytokines (i.e. IL-6, TNF-, INF-) inhibiting differentiation and proliferation activities of erythroid cells in(More)
In order to identify subjects at higher risk for carotid stenosis and to provide insights into mechanisms of disease development at different age-intervals, a color duplex ultrasound of extracranial arteries was performed in 624 consecutive patients (mean age 62.9+/-10.7, 483 males) undergoing coronary angiography. Significant carotid atherosclerosis (> or(More)
Diagnosis of prosthetic joint infections (PJIs) remains a challenge for microbiologists, despite new techniques for bacteria isolation have been developed in recent years. A widely recognized standard method has not yet been indicated mainly because of limitations due difficult procedures and need of dedicated instrumentation. We evaluated the ability of a(More)
PURPOSE Staphylococci are responsible for approximately half of all prosthetic joint infections (PJIs) and they are often multi-drug resistant. The main purpose of this study was to evaluate the incidence of PJIs caused by staphylococci in our hospital from March 2010 to February 2012, with particular reference to antibiotic resistance in relation to their(More)
INTRODUCTION Staphylococcus aureus and coagulase-negative staphylococci (CoNS) colonization among healthcare workers (HCWs) may have implications in development of infections and in spreading of resistance. This study aimed to determine the rate of methicillin-resistant staphylococci carriage in HCWs of spinal surgeries in an Italian Orthopaedic Institute.(More)
To address the problem of limited efficacy of existing antibiotics in the treatment of bacterial biofilm, it is necessary to find alternative remedies. One candidate could be hyaluronic acid; this study therefore aimed to evaluate the in vitro antiadhesive and antibiofilm activity of hyaluronic acid toward bacterial species commonly isolated from(More)
Endocannabinoids are a class of lipid mediators involved in a wide range of physiological pathways including pain perception, and immunological defences. In particular, the involvement of endocannabinoids in bone metabolism and bone resorption has recently been studied. Moreover, one study on total knee arthroplasty describes the probable role of(More)
Osteonectin, also termed SPARC, is a noncollagenous protein of bone matrix. Since there are controversial results regarding its role during the process of vascular calcification, we investigated osteonectin expression in our in vitro calcification model. Rat vascular smooth muscle cells (VSMCs) were challenged with high phosphate (5 mmol/L Pi) and analyzed(More)
