OBJECTIVE Advanced glycation end products (AGEs) have pathophysiological implications in cardiovascular diseases. The aim of our study was to evaluate the prognostic value of fluorescent AGEs and its soluble receptor (sRAGE) in the context of acute coronary syndrome (ACS), both in-hospital phase and follow-up period. METHODS A prospective clinical study(More)
Knowledge of the role of the soluble receptor for advanced glycation end products (sRAGEs) in chronic heart failure (CHF) is very limited. In the present study, we measured plasma sRAGE levels in patients with CHF and examined whether plasma sRAGE predicts prognosis in patients with HF independently of validated scores as the Seattle Heart Failure Score(More)
BACKGROUND Hyperglycaemia induces non-enzymatic glycation reactions in proteins which generate Amadori products and advanced glycation end-products; the latter are thought to participate in the vascular complications of diabetic patients. However, the exact mechanisms concerning the effects of glycated proteins on vascular tissue remain to be determined.(More)
BACKGROUND Recent studies suggested that advanced glycation end-products (AGEs) and their receptor (RAGE) interaction may be promoted by inflammation and oxidative stress. These processes could also contribute to the pathogenesis of atrial fibrillation (AF), but their roles remain poorly defined. We studied the association of AGE-RAGE axis with AF in(More)
AIMS Knowledge of the role of advanced glycation end products (AGE), their receptor (RAGE), and the receptor's soluble form (sRAGE), in heart failure (HF) is very limited. We evaluated the clinical role of the AGE-RAGE system in HF and in particular any association it might have with ischaemic aetiology. METHODS AND RESULTS We measured fluorescent AGE,(More)
OBJECTIVE Obesity, a risk factor for coronary artery disease (CAD), is associated with inflammation and reactive oxygen species (ROS) production, while advanced glycation end-products, through their receptor (AGER or RAGE), play an important role on these processes. The aim of this study was to analyze the expression levels of RAGE, NADPH oxidase subunits,(More)
The interface between the intestinal lumen and the mucosa is the location where the majority of ingested immunogenic particles face the scrutiny of the vast gastrointestinal immune system. Upon regular physiological conditions, the intestinal microflora and the epithelial barrier are well prepared to process daily a huge amount of food-derived antigens and(More)
BACKGROUND AND AIMS Altered intestinal barrier is associated with immune activation and clinical symptoms in diarrhoea-predominant IBS (IBS-D). Increased mucosal antigen load may induce specific responses; however, local antibody production and its contribution to IBS aetiopathogenesis remain undefined. This study evaluated the role of humoral activity in(More)
Endothelial dysfunction has been linked to reactive oxygen species (ROS) production by nicotinamide adenine dinucleotide phosphate reduced (NADPH) oxidase. Angiotensin II (ANG), which levels are elevated in some cardiovascular diseases, can stimulate this enzyme, whereas statins have been demonstrated pleiotropic effects related with the restoration of(More)
Procyanidins have been associated with a reduced risk of cardiovascular diseases such as atherosclerosis. However, the molecular mechanisms underlying this benefit are not fully understood. Increased reactive oxygen species (ROS) production generated by nicotinamide adenine dinucleotide phosphate (NADPH) oxidase is a common problem in different(More)
