    Il professore e la casa editrice

    No full text
    Il saggio ripercorre il carteggio che il professore Augusto Monti intrattenne con i redattori della casa editrice Einaudi, un tempo suoi alunni. Nell'accogliere le proposte di pubblicazione del professore, i redattori si dimostrano in lotta tra il severo giudizio editoriale e il tenero debito filiale che sentivano di avere nei confronti dell'anziano maestro. Il ritratto che ne emerge restituisce umanità, al di là del mito, ad una figura di grande rilievo per la storia dell'Einaudi e della scuola italiana

    Impaired Cerebral Perfusion in Multiple Sclerosis: Relevance of Endothelial Factors

    No full text
    Magnetic resonance imaging techniques measuring in vivo brain perfusion and integrity of the blood-brain barrier have developed rapidly in the past decade, resulting in a wide range of available methods. This review first discusses their principles, possible pitfalls, and potential for quantification and outlines clinical application in neurological disorders. Then, we focus on the endothelial cells of the blood-brain barrier, pointing out their contribution in regulating vascular tone by production of vasoactive substances. Finally, the role of these substances in brain hypoperfusion in multiple sclerosis is discussed

    Influence of Circulating Endothelin-1 and Asymmetric Dimethylarginine on Whole Brain Circulation Time in Multiple Sclerosis

    Blood-brain barrier (BBB) breakdown, inflammatory and immune cell activation, and chronic cerebral hypoperfusion are features of multiple sclerosis (MS). The aim is to determine the influence of endothelin-1 (ET1) and asymmetric dimethylarginine (ADMA) on cerebral circulation time (CCT) in patients with MS. In all, 64 patients with MS (39 relapsing-remitting [RR]-MS; 25 secondary progressive [SP]-MS subtype) and 37 controls (C) were studied. Cerebral circulation time was obtained by angiography. Plasmatic ET1 and ADMA were measured by enzyme-linked immunosorbent assay. Lesion load (LL) and brain volume (BV) were obtained by magnetic resonance imaging. Cerebral circulation time was correlated to ET1, ADMA, LL, BV, disease duration (DD), and Expanded Disability Status Scale (EDSS). In MS, both ET1 and ADMA were significantly higher than C (P < .0001); CCT was approximately 2 times lower than C (P < .0001) and significantly slower in SP than in RR-MS (P = .0215). Cerebral circulation time significantly correlated with ET1 in SP-MS (r = 0.38), whereas in RR-MS CCT significantly correlated with DD (r = 0.75). The LL, BV, and EDSS did not correlate with CCT. Endothelin-1 significantly influences CCT delay in SP-MS. Diversely, CCT in RR-MS is independent of ET1 and correlates significantly with DD. We conclude that in RR-MS, DD responds to neurovascular damage accumulation. It is supposed that high ET1 and ADMA levels stem from a protective response to early insults, aimed at opposing nitric oxide overproduction, whereas persistent pathological ET1 and ADMA levels translate into detrimental long-term effects, due to increased brain micro-vessel resistance

    Petrarca maestro di spiritualità. La Senile X 1 per la monacazione di Sagremor de Pommiers

    No full text
    La Sen. X1 costituisce una lunga lettera di istruzione spirituale sotto il segno di s. Agostino e s. Bernardo rivolta ad un amico che ha compiuto in età adulta la scelta monastica. Si tratta di una delle lettere petrarchesche in cui più fitta è la presenza di citazioni bibliche

    Education and Training in St.Lucia: A Partially Annotated Bibliography

    No full text
    This bibliography on “Education and Training in St. Lucia” has been specifically prepared for the UWI School of Continuing Studies’ St. Lucia Country Conference. An attempt has been made to be as comprehensive as possible, but because of the weak bibliographical coverage of the literature of the region, important items may have been omitted. This is especially true for policy documents emanating from official sources. It covers all aspects of education and training in St.Lucia including distance education, educational finance,health and family life education and educational reform
