L’articolo si interroga sul metodo più corretto per valutare la presenza di varianti autoriali all’interno delle opere boccacciane, prendendo in esame l’ipotesi della seconda redazione della Comedia delle ninfe fiorentine, testimoniata in via esclusiva dall’edizione del 1520 curata da Girolamo Claricio. Un nuovo esame della posizione stemmatica della stampa e di alcune lezioni particolari da essa tramandate sembra suggerire la paternità clariciana degli interventi innovativi, inquadrabili all’interno del progetto culturale portato avanti dall’editore imolese. Si discute inoltre del rapporto della stampa con un presunto antigrafo copiato da Francesco d’Amaretto Mannelli e dell’uso che Claricio fa del nome dell’illustre copista a sostegno delle sue posizioni nel coevo dibattito sulla lingua. This article investigates the correct method to evaluate the presence of authorial variants in Boccaccio’s works, focusing on the hypothetical second version of the Comedia delle ninfe fiorentine, transmitted only by the print published by Girolamo Claricio in 1520. A new exam of its stemmatic position and of some of its peculiar variants suggests to ascribe them to Claricio and his cultural project. Furthermore, the article discusses the connection between the print and its supposed antigraph copied by Francesco d’Amaretto Mannelli, whose name is used by Claricio to strengthen his position in the contemporary debate on language.

L’articolo evidenzia l’importanza di un’indagine ad ampio spettro sulla tradizione del Decameron, sia per la corretta definizione dei rapporti tra l’autografo Hamilton 90 e il codice Mannelli, problema centrale per la constitutio textus, sia per una migliore comprensione delle dinamiche di trasmissione del testo. Attraverso il riscontro con la principale tradizione manoscritta, sono prima analizzati alcuni casi di varia lectio riguardante l’onomastica decameroniana, al fine di valutare la diffusione di determinate varianti: alcune di esse, di cui in passato era stata prospettata l’autorialità, sono invece ricondotte all’intervento di singoli copisti. Il riesame di alcuni loci critici induce inoltre a riconsiderare l’affidabilità del codice Mannelli, con ricadute concrete anche sulla corretta costituzione del testo critico dell’opera: in particolare viene proposta una diversa soluzione testuale per l’incipit del Decameron, passo per cui la testimonianza dell’autografo è assente. The article enlightens the importance of a wide investigation of the textual tradition of the Decameron, both for the correct definition of the relation between the autograph Hamilton 90 and the Mannelli codex, and for a better comprehension of the dynamics of textual transmission. Through the examination of the most important manuscripts of the tradition, the article analyses some cases concerning decameronian onomastics in order to evaluate the spread of single variants, some of which, attributed in the past to the author, are instead ascribed to copyists. In addition, the article reconsiders the reliability of the Mannelli codex, which is still used by editors to reconstruct those portions of text that are missing in the autograph: in particular, a different textual solution is proposed for the incipit of the Decameron.

Background: In the development of hypertensive microvascular remodeling, a relevant role may be played by changes in extracellular matrix proteins. Aim of this study was the to evaluate some extracellular matrix components within the tunica media of subcutaneous small arteries in 9 normotensive subjects and 12 essential hypertensive patients, submitted to a biopsy of subcutaneous fat from the gluteal or the anterior abdominal region. Patients and Methods: Subcutaneous small resistance arteries were dissected and mounted on an isometric myograph, and the tunica media to internal lumen ratio was measured. In addition, fibronectin, laminin, transforming growth factor-beta-1 (TGF-β1) and emilin-1 contents within the tunica media were evaluated by immunofluorescence and relative immunomorphometrical analysis (immunopositivity % of area). The total collagen content and collagen subtypes within the tunica media were evaluated using both Sirius red staining (under polarized light) and immunofluorescence assay. Results: Normotensive controls had less total and type III collagen in respect with hypertensive patients. Fibronectin and TGF-β1 tunica media content was significantly greater in essential hypertensive patients, compared with normotensive controls, while laminin and emilin-1 tunica media content was lesser in essential hypertensive patients, compared with normotensive controls. A significant correlation was observed between fibronectin tunica media content and media to lumen ratio. Conclusions: Our results indicate that, in small resistance arteries of patients with essential hypertension, a relevant fibrosis may be detected; fibronectin and TGF-β1 tunica media content is increased, while laminin and emilin-1 content is decreased; these changes might be involved in the development of small resistance artery remodeling in humans.
