The authors review equine granulocytic ehrlichiosis (EGE) in Italy from 1996 to 2002. In 1996, the first case of EGE has been observed in a horse affected with specific symptomatology (fever, lethargy, anorexia, limb edema, thrombocytopenia, and petechiae). In 1997, a seroepidemiological survey was performed in the province of Rome on 563 animals using(More)
Magnetocardiography (MCG) is the recording of the magnetic field (MF) generated by cardiac electrophysiological activity. Because it is a contactless method, MCG is ideal for noninvasive cardiac mapping of small experimental animals. The aim of this study was to assess age-related changes of cardiac intervals and ventricular repolarization (VR) maps in(More)
Lipoapoptosis has been described in many organs and tissues, but never in enterocytes. We hypothesized that a high saturated-fat diet can induce duodenal enterocyte apoptosis and impair gastric inhibitory polypeptide (GIP) secretion. Forty male Wistar rats, ∼4 months old, were randomized on standard laboratory or purified tripalmitin-based high-fat diet(More)
Nutrition during fetal life is a critical factor contributing to diabetes development in adulthood. The aim of our study was to verify: 1) whether a high-fat (HF) diet in young adult mice induces alterations in beta-cell mass, proliferation, neogenesis, and apoptosis, as well as insulin sensitivity and secretion; 2) whether these alterations may be(More)
Incretins are hormones released by enteroendocrine cells in response to meals, depending upon absorption of nutrients. The present study aimed to elucidate the mechanisms through which a high-fat diet (HFD) induces insulin resistance and insulin hypersecretion by focusing on the effects on enteroendocrine cells, especially those secreting glucose-dependent(More)
Cardiac pathologies are among the leading causes of mortality and morbidity in industrialized countries, with myocardial infarction (MI) representing one of the major conditions leading to heart failure (HF). Hitherto, the development of consistent, stable, and reproducible models of closed-chest MI in large animals, meeting the clinical realism of a(More)
OBJECTIVE To investigate the effects of N-acetylcysteine (NAC) and high-dose atorvastatin (ATOR) in reducing oxidative stress in a rat kidney model of ischemia-reperfusion injury. METHODS Forty female rats underwent clamping of the left renal artery for 30 minutes, followed by reperfusion. The effects of pre-ischemic administration of NAC and/or ATOR were(More)
This study aims to investigate engraftment of human cord blood and foetal bone marrow stem cells after in utero transplantation via the intracoelomic route in the sheep. Here, we performed transplantation in 14 single and 1 twin sheep foetuses at 40-47 days of development, using a novel schedule for injection. (i) Single injection of CD34(+) human cord(More)
Guinea pigs (GPs) are used for preclinical evaluation of electrophysiologic effects of new drugs, because their myocytes have human-like action potentials and ventricular repolarization's (VR) ion currents. This study was aimed to assess the reliability of magnetocardiographic (MCG) mapping for longitudinal studies of GP cardiac electrical activity.(More)
BACKGROUND Epidemiologic data in volcanic areas suggest that environmental factors might be involved in the increase of thyroid cancer (TC) incidence. Recent reports indicate that several heavy metals and metalloids are increased in volcanic areas. This study aims to evaluate the combined effect of three of these elements Boron (B), Cadmium (Cd), and(More)
