A perfusion model of global cerebral ischemia was used for the immunohistochemical study of changes in the glutamate-nitric oxide (NO) system in the rat cerebellum and cerebellar nuclei during a 0-14 h reperfusion period after 30 min of oxygen and glucose deprivation, with and without administration of 1.5 mM N(omega)-nitro-L-arginine methyl ester (L-NAME).(More)
Adrenomedullin (AM) is a novel vasodilator peptide first purified from human pheochromocytoma by tracing its capacity to stimulate cAMP production in platelets. AM immunoreactivity is widely distributed in the central nervous system (CNS) and in the rat has been demonstrated by immunohistochemical techniques to be present in many neurons throughout the(More)
BACKGROUND The cytokine profile plays an important role in treatment outcome of hepatitis C virus (HCV) infection, and probably modulates the immune response against HCV. The aim of this study was to evaluate which cytokines affect the response to interferon-α (IFN-α) and ribavirin therapy and how these cytokines change 72 weeks after starting anti-HCV(More)
BACKGROUND Hyaluronic acid (HA) serum levels correlate with the histological stages of liver fibrosis in hepatitis C virus (HCV) monoinfected patients, and HA alone has shown very good diagnostic accuracy as a non-invasive assessment of fibrosis and cirrhosis. The aim of this study was to evaluate serum HA levels as a simple non-invasive diagnostic test to(More)
Changes in the pattern of adrenomedullin expression in the rat cerebral cortex after ischemia-reperfusion were studied by light and electron microscopic immunohistochemistry using a specific antibody against human adrenomedullin (22-52). Animals were subjected to 30 min of oxygen and glucose deprivation in a perfusion model simulating global cerebral(More)
Today, methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) emissions represent approximately 98 % of the total greenhouse gas (GHG) inventory worldwide, and their share is expected to increase significantly in this twenty-first century. CO2 represents the most important GHG with approximately 77 % of the total GHG emissions (considering its global(More)
Torque teno virus (TTV) and torque teno mini virus (TTMV) have been potentially related to liver diseases. The aim of the study was to quantify TTV and TTMV in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients to study the relationship between the TTV and TTMV viral loads and the severity of liver disease. We carried out a(More)
The multiple criteria aggregation methods allow us to construct a recommendation from a set of alternatives based on the preferences of a decision maker. In some approaches, the recommendation is immediately deduced from the preferences aggregation process. When the aggregation model of preferences is based on the outranking approach, a special treatment is(More)
