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)
Laser pulses selectively excite mechano-thermal nociceptors and evoke brain potentials that may reveal small-fiber dysfunction. We applied CO2-laser pulses to the perioral and supraorbital regions and recorded the scalp laser-evoked potentials (LEPs) and reflex responses in the orbicularis oculi, masticatory, and neck muscles in 30 controls and 10 patients(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)
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)
Serum bile acids were determined in 13 cirrhotic patients with portacaval shunt and in 15 with mesocaval shunt. 20 nonshunted cirrhotics were used as controls. Serum bile acid levels were higher in portacaval (26.7 +/- 14.3 micrograms/ml) than in mesocaval shunt patients (16.9 +/- 8.1 micrograms/ml) and controls (14.1 +/- 11.5 micrograms/ml). The(More)
We recorded electrically stimulated somatosensory evoked potentials (electric SEPs) and pain-related SEPs following CO2 laser stimulation (CO2 laser SEPs) from a 17-year-old patient affected by myotonic dystrophy whose MRI disclosed a large syrinx extending from spinal level C2 to S3. Careful clinical and electromyographic examinations revealed no motor or(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)
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)
Glycoprotein hormone free alpha subunit has been used as a marker for some pituitary tumors and to study the reactivity of glycoprotein hormone-producing cells under different circumstances. We describe a highly sensitive and specific immunofluorometric assay for the measurement of serum free alpha subunit levels. The assay is based on a monoclonal(More)
