Comportamento del coefficiente di rigidità sclerale di occhi normali e glaucomatosi dopo somministrazione orale di glicerolo (Behaviour of the scleral rigidity coefficient in normal and glaucomatous eyes after oral administration of glycerol)
No full textE' stata notata una modesta diminuzione del coefficiente di rigidità sclerale dopo somministrazione orale di glicerolo (g. 1/Kg) in soggetti normali ed in pazienti affetti da vari tipi di glaucoma. Tale modificazione non è sembrata essere significativa. Gli Autori fanno alcune considerazioni su tale fenomeno
Radial head fractures: review of current evidence about assessment, classification and management
No full textThe radial head fractures are frequent elbow injuries with several fracture patterns and associated lesions. The literature highlights the importance of correct patient management right from the earliest stages to achieve the best results and to avoid complications. The purpose of this article was to provide an overview of current concepts of the management of radial head fractures. The main goal of each treatment should be to restore elbow biomechanics, kinematics and stability to achieve a complete range of motion and to early begin rehabilitation programs. For Mason type 1 fractures the nonoperative management is the best choice providing good or excellent results in most patients. There is less agreement regarding Mason type 2 fractures, in term of nonoperative or surgical treatment. When surgical treatment is chosen, open reduction and internal fixation seems to guarantee the best clinical outcomes with excellent results reported. The Mason type 3 or 4 fractures are managed with surgical treatment. However, the best method of treatment remains controversial in literature between open reduction and internal fixation, radial head arthroplasty and radial head excision. In the last years, arthroscopy is going to assume an important role in the management of elbow diseases, not only as diagnostic tool but also as surgical solution and probably in the future its role will become more and more relevant. Further studies with long-term follow-up are needed to determine the best form of treatment of these complex injuries.

Di tracce della presenza del digamma in recitazioni "parallele" di Omero, Appendice
No full textThe well-attested presence of digamma in epigraphic poetic texts (from 7th-6th century BC) in all probability linked to Homeri tradition, seems to allude to recitations of the Poems in which it was not only limited to producing well-known metrical effects, but also actually pronounced and heard. The picture emerging from the evidence analysed in this paper appears to be perfectly in line with a linguistic and cultural framework
Reaction of phenylglyoxal with arginine groups in D-amino acid oxidase from Rhodotorula gracilis
No full textD-Amino-acid oxidase from Rhodotorula gracilis was irreversibly inactivated by phenylglyoxal in a biphasic process. The fast phase was completed in less than 1 min. Its extent was linearly dependent on phenylglyoxal concentration and was not influenced by the presence of FAD or benzoate, a pseudo-substrate. The second phase of inactivation was due to a simple second-order reaction. The presence of FAD exerted only partial protection; the second-order rate constants of inactivation were 8.3 M-1 min-1 for holoprotein and 18.0 M-1 min-1 for apoprotein. The addition of benzoate completely protected against this second phase of inactivation. Efforts to isolate the enzyme modified at a single arginine residue at the end of the fast phase were unsuccessful, but analysis of the enzyme isolated at the end of the slow phase identified an arginine residue, protected by benzoate, that is highly conserved in all D-amino-acid oxidases and corresponds to Arg283 in the pig kidney enzyme. Modification of this residue is directly involved in the inactivation process during the slow phase. This arginine may represent the basic residue ion pairing with the carboxylate group of the substrate or the residue interacting with the flavin N1-C2 = O locus
Mediterranean Movements and Constituent Political Spaces: An Interview with Sandro Mezzadra and Toni Negri
No full textThese conversations between Toni Negri and Sandro Mezzadra (November 2014–October 2015) focus on the politics of Mediterranean boundaries and situate migratory movements across the Mediterranean in the geopolitical context of the Eastern and Southern shore. Looking at the proliferation of wars around the Mediterranean region and reflecting on the legacy of the Arab Uprisings, Mezzadra and Negri revisit the concept of the “autonomy of migration” and critically interrogate its possible contribution to the field of migration and in terms of the current refugee crisis
Foundation and empire : a critique of Hardt and Negri
No full textIn this article, Thompson complements recent critiques of Hardt and Negri's Empire (see Finn Bowring in Capital and Class, no. 83) using the tools of labour process theory to critique the political economy of Empire, and to note its unfortunate similarities to conventional theories of the knowledge economy
Cuspidaria lamellosa Sars M. in Sars G. O. 1878
No full textCuspidaria lamellosa (Sars M. in Sars G. O., 1878) Fig. 10 f–h Neaera lamellosa Sars M. in Sars G. O., 1878 (p. 88, pl. 6, figs. 9a–c). Cuspidaria lamellosa M. Sars [in text] Sars [in plate]—Dall 1889[b] (p. 66, pl. 45, fig. 3). Cuspidaria lamellosa (M. Sars) Dall—Verrill & Bush 1989 (p. 799, pl. 74, fig. 10).? Cuspidaria jugosa (S. Wood, 1856) — Nordsieck 1969 (p. 176, pl. 25, fig. 98.74). Cuspidaria lamellosa (M. Sars, 1858) — Thomsen & Vorren 1986 (pl. 8, fig. A). ? Cuspidaria jugosa (Wood S., 1856) — Repetto et al. 2005 (p. 354, bottom right fig.). Cuspidaria lamellosa (G.O. Sars, 1872) — Oliver et al. 2016 (online resource). Diagnostic characters. Oval shell; rounded anterior side; long and truncate posterior rostrum; right valve hinge with a strong posterior lateral tooth; radial ridge from the beaks to the ventral angle of the rostrum; rather evenly spaced commarginal lamellae, vanishing on the umbonal area and over the rostrum. Prodissoconch: shell type ST- 2D; length about 130 µm; ellipsoidal outline; convex profile; P-1 surface finely granulated; P-1/P-2 boundary illdefined; rim-like P-2; transition to the nepioconch well marked. Remarks. G.O. Sars (1878, p. 88) erroneously considered the valid species Neaera lamellosa M. Sars as conspecific with Neaera jugosa S. Wood. Actually, Cuspidaria jugosa (Wood S.V., 1857), although subsequently put in synonymy of C. lamellosa by some authors (e.g. Nordsieck 1969), appears to be a different species, as Wood (1857: p. 272) described it as possessing “eight to ten rounded ridges, with depressions or sulci between them of about the same breadth”. Occurrence. Box-corer samples BC05 (2 specimens), BC66 (1), BC72 (6); core BC72 (2). Maximum length: 3.5 mm. Distribution and habitat. The species is found at outer shelf depths in Norway waters, and at deeper settings (down to 1100 m) along both the Atlantic margins; it is an infaunal burrower inhabiting soft bottoms (Dall 1889[b]; Thomsen & Vorren 1986; Buhl-Mortensen & Høisaeter 1993; Oliver et al. 2016).
