Analisi carpologiche per la Vasca dello Specchio (Ferrara, XIV-XV sec. d.C.): metodologie d’indagine e risultati
No full textLo scavo condotto tra Corso Porta Reno e Via Vaspergolo, nel centro storico di Ferrara, ha portato alla luce un vano sotterraneo rettangolare denominato “Vasca dello Specchio”, utilizzato per lo smaltimento dei rifiuti tra XIV e XV secolo. Il riempimento, in parte già analizzato e pubblicato, è stato oggetto di nuove analisi carpologiche. I semi e i frutti, conservati prevalentemente per sommersione e in ottimo stato, sono complessivamente oltre 400.000 e la lista floristica comprende 168 taxa. La maggior parte dei reperti appartiene a piante coltivate/coltivabili o spontanee correlate all’uomo, che forniscono nuove informazioni sulla dieta vegetale e sull’ambiente urbano della Ferrara basso-medievale/rinascimentale. I reperti evidenziano anche pratiche domestiche e culinarie talora curiose

No full textHuman osteoblast-like cell proliferation induced by calcitonin-related peptides involves PKC activity
No full textThe calcitonin peptides [calcitonin (CT), calcitonin gene-related peptide (CGRP), amylin] share many biological actions, including activity on bone cells. In the present study, CT (10(-11) to 10(-9) M) stimulated [(3)H]thymidine incorporation in primary cultures of human osteoblasts (hOB), as already demonstrated for CGRP and amylin. RT-PCR analysis showed that the calcitonin receptor and the calcitonin receptor-like receptor are both expressed in hOB. In these cells, CT (10(-10) M) and amylin (10(-9) M), in contrast to CGRP (10(-8) M), did not increase cAMP production. All three peptides stimulated protein kinase C (PKC) activity. To evaluate PKC involvement in hOB proliferation, cells were incubated with phorbol 12,13-dibutyrate, a stimulator of PKC activity; cell proliferation was increased in a dose-dependent manner (EC(50) = 3.4 x 10(-8) M). Staurosporine (10(-9) M), a PKC inhibitor, blocked phorbol 12,13-dibutyrate-induced PKC activity and cell proliferation. Inhibition of PKC by staurosporine also counteracted the stimulatory effect of CT, CGRP, and amylin on hOB proliferation. From these data, it is deduced that the activation of PKC is important for hOB proliferation and that it is involved in the anabolic effect of CT peptides on bone
"Illud quod est caput omnium: l'espulsione dei moriscos e la canonizzazione di Juan de Ribera.
No full textRipercorrendo le tappe settecentesche del processo di canonizzazione di Juan de Ribera, un Memoriale anonimo destinato al papa e il più consistente materiale preparatorio, rintracciati entrambi presso l’Archivio del Collegio del Corpus Christi di Valencia, consento- no di vedere all’opera il Santo Uffizio romano. Interpellato sulla causa, esso produce una se- rie di obiezioni stringenti contro l’espulsione dei moriscos, soprattutto dei bambini, contro l’atteggiamento e l’operato dell’arcivescovo, la mancata consultazione della Sede apostolica e la convocazione di sinodi provinciali. Queste critiche, per quanto tocchino questioni nevralgiche e controverse, a cui i difensori della causa di Ribera danno risposte talvolta discutibili, talaltra evasive, rallentano ma non arrestano la causa. Essa sarà decisa d’imperio dal pontefice che, nel 1796, lo dichiarerà beato.As the campaign for the canonization of Juan de Ribera unfolded in the eighteenth century, an anonymous author wrote a forcefully argued summary intended for the pope. The petition, housed in the archive of the Colegio de Corpus Christi, Valencia, sheds light upon the internal workings of the Holy Office in Rome. This critique of the canonization effort raised a series of powerful objections, to Ribera’s ideas and programs as archbishop; and to his failure to consult the papacy or convene a provincial synod. These controversial criticisms struck a nerve with Ribera’s defenders, who offered debatable or evasive responses. Ultimately these objections slowed down but did not stop the campaign on Ribera’s behalf, as in 1796 the papacy declared his beatification
Computerised tomography evaluation of the frontal recess in inflammatory diseases of the frontal sinus: Standardisation of a new technique
No full textThe authors present a new investigation technique by means of CT of the frontal sinus drainage pathway, the frontal recess, which could be of considerable help in defining its potential role in determining a chronic or recurrent inflammatory process of this cavity. Among the main characteristics of this technique are: (1) a clear presentation of the course and conformation of the recess and its relations with surrounding structures; (2) speedy, and therefore economical, operation (12 min for a complete examination); and (3) tolerability, because this examination starts off with axial-scans, which, compared to CT coronal projections and MRI scans, are less prone to defects and do not require strained postures. This this means that all kinds of patients can be assessed, which is a basic requirement for achieving standardisation. With axial scans the authors work from paraxial reconstructions (oblique sagittal) which, in their opinion, give the best definition of the frontal recess so far recorded
