Cerebral blood flow in patients with chronic cerebrovascular disease: effect of acetyl L-carnitine
No full textThe effect of acetyl-L-carnitine on cerebral blood flow was evaluated in ten patients with cerebrovascular disease, who suffered an ischaemic stroke at least six months before the study. All patients performed a computerized tomograph scan and were investigated by Xenon 133 using a brain dedicated Single Photon Emission Computerized Tomography. Acetyl-L-carnitine was administered intravenously (i.v.) at a dosage of 1.5 g. Cerebral blood flow (ml/min. 100 g) was evaluated before and 45 min after the injection. Cerebral blood flow improved in both the ispilateral and controlateral hemisphere of the ischaemic area, but not in the stroke corresponding zone. It is concluded that acetyl-L-carnitine at a dosage of 1.5 g i.v. improves cerebral blood flow in patients with cerebrovascular disease
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
La Frentania. Profilo storico, archeologico e topografico (VI-I sec. a.C.)
No full textQuesta tesi nasce dal desiderio di tracciare un profilo diacronico dell’occupazione della regione frentana, nella zona compresa tra il corso del fiume Foro e il fiume Biferno, nella fascia costiera dell’Abruzzo meridionale e del Molise. Se ne traccia un profilo storico, archeologico e topografico
