AIMS Recent data suggest that the administration of bone marrow-derived stem cells (BMSC) might improve myocardial perfusion and left ventricular (LV) function after acute myocardial infarction (AMI). The aim of this study was to assess spontaneous mobilization of BMSC expressing the haematopoietic and endothelial progenitor cell-associated antigen CD34+(More)
BACKGROUND Despite increasing pharmacological and mechanical treatment options, coronary artery disease (CAD) continues to be associated with considerable mortality and morbidity. The detrimental effects of elevated heart rate (HR) on cardiac morbidity and mortality are well established. Although β-blockers represent the mainstay of treatment of patients(More)
A monoclonal antibody-based immunoenzymometric assay (IEMA) for the measurement of human serum growth hormone is described. Two high-affinity and complementary monoclonal antibodies were selected from a panel of 9 obtained upon fusion of SP2/O myeloma cells with spleen cells from a Balb/c mouse immunized against human growth hormone of pituitary origin. One(More)
Data obtained during the past five years have indicated that there are important age- and gender-based differences in the regulation and action of leptin in humans. To study the physiological changes of leptin during puberty in both sexes, and its relationship with body composition and sexual maturation, we measured leptin concentrations in 175 healthy(More)
This paper describes an immunofluorometric assay (IFMA) for insulin and compares it with the classical radioimmunoassay (RIA). Monoclonal antibodies against insulin were produced and used to develop the IFMA. One, immobilized on microtiter plates, was used for capture, the other, labelled with Europium, was used as tracer antibody. The IFMA presents(More)
Retinol-binding protein (RBP) is a low-molecular-mass protein (21 kDa), easily filtered in renal glomeruli and very efficiently reabsorbed by the proximal convoluted tubules (PCTs). In PCT dysfunction, high concentrations of RBP are found in urine. Several methods have been used to determine RBP in serum or urine. We describe the production, selection,(More)
We describe a time-resolved fluoroimmunoassay specific for human proinsulin using a combination of two high-affinity monoclonal antibodies, one against insulin and the other specific for intact proinsulin and for split 65-66 and des 64-65 proinsulin forms. The assay employs only 200 microl of serum, with a detection limit of 0.1 pmol/l. The intra-assay(More)
Widespread plaque inflammation has been demonstrated in acute coronary syndromes (ACS). We evaluated signs of plaque inflammation in carotid arteries of patients with ACS by contrast-enhanced magnetic resonance imaging (MRI). Carotid MRI was performed in 13 patients with ACS and in 9 controls having at least 1 carotid plaque with a stenosis > or =40%. MRI(More)
In men, cardiovascular diseases (CVD) increase steadily by the age of 35 years and reach a plateau in the 7th decade of life, whereas in women few years after the menopause, from about 50 years, the incidence of cardio-cerebro-vascular diseases progressively increases, becoming the leading cause of mortality and morbidity. Because of the greater incidence(More)
OBJECTIVE Non-steroidal anti-inflammatory drugs (NSAID) can induce enteropathy. Aspirin ingestion is associated with a lower small-intestinal inflammation than other NSAID. Faecal calprotectin concentrations have recently been proposed as a simple non-invasive test to identify NSAID enteropathy. The aim of our pilot study was to evaluate calprotectin(More)
