Purification and characterization of leucine aminopeptidase from kidney bean cotyledons
1992
A leucine aminopeptidase (EC 3,4,11.1) was purified from cotyledons of resting kidney beans (Phaseolus vulgaris L. cv. Processor) by acidic extraction, ammonium sulfate fractionation and chromatography on DEAE-Sephacel, Sephacryl S-300, Mono Q HPLC and Superose HPLC columns. The yield of the 317-fold purified enzyme was 9%. On gel filtrations on Sephacryl S-300 and Superose HPLC the elution volumes of the enzyme corresponded to an M, of 360 000. The enzyme gave one band on native gel electrophoresis and an electrophoretic titration in an immobilized pH gradient gave a single curve with a pI of 4.8. Two bands were observed in an SDS-gel electrophoresis with Mr values of 58 000 and 60 000 bot…
Deformabilità eritrocitaria, metaboliti dell'ossido nitrico e stress ossidativo in un gruppo di soggetti con sindrome delle apnee ostruttive nel sonno
2015
La sindrome delle apnee ostruttive nel sonno ((OSAS) si associa a disfunzione endoteliale ed aterosclerosi ed è gravata da un'elevata morbilità e mortalità cardiovascolare.
Riflessioni critiche sulla potenza destituente nel pensiero di Giorgio Agamben
Il presente lavoro di ricerca intende offrire una rilettura del pensiero di Giorgio Agamben alla luce della pubblicazione di L’uso dei corpi, volume con cui si conclude il ventennale progetto “Homo sacer”. In particolare, si discuteranno alcune nozioni fondamentali della filosofia agambeniana – nuda vita, stato di eccezione, inoperosità, forma-di-vita – a partire dalla formulazione conclusiva, ma non definitiva, che il filosofo propone nel libro in questione, per poi focalizzare l’attenzione sulla categoria nella quale si condensa l’intero percorso filosofico di Agamben: la “potenza destituente”. Quest’ultima viene definita come una potenza in grado di disattivare e rendere inoperosa la mac…

Interrelazioni tra disfunzione endoteliale e stress ossidativo; valutazione della perossidazione lipidica in particolari quadri clinici
2015
Il termine "disfunzione endoteliale" identifica una condizione patologica caratterizzata da ridotta vasodilatazione e da attività procoagulante e pro-infiammatoria, correlata ad una ridotta biodisponibilità di ossido nitrico (NO), ad un eccesso ossidativo e ad un'aumentata azione dell'endotelian 1 (ET-1).
Structural and electronic properties of ion-exchangeable layered perovskites
2013
The modification of metal oxide surfaces with organic moieties has been widely studied as a method of preparing organic-inorganic hybrid materials for various applications. Among inorganic oxides, the ion-exchangeable layered perovskites, materials composed by perovskite-like slabs (ABO3, in which B is a small transition metal cation and A is a larger s-, d- or f-block cation) and intercalated cations, stimulated authors’ interest in reason of some encouraging electronic and reactive properties. In particular it is well known that the interlayer surface of layered-perovskites in their protonated form can be easily functionalized with organic groups, such as alcohols, organophosphonic acids,…
Hyperosmolar therapy for acute brain injury: study protocol for an umbrella review of meta-analyses and an evidence mapping
2020
Introduction Acute brain injury is a challenging public health problem worldwide. Elevated intracranial pressure is a common complication after acute brain injury. Hyperosmolar therapy is one of the main therapeutic strategies for the management of intracranial hypertension. This study protocol outlines an umbrella review of meta-analyses which will investigate the benefits and harms of hyperosmolar therapy routinely used for the management of acute brain injury in the intensive care. Methods and analysis We will search PubMed/MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews. We will include meta-analyses of primary research studies (eg, randomised controlled trials, observat…
Successful treatment of primary chronic osteomyelitis in SAPHO syndrome with bisphosphonates.
2008
Summary The treatment of the painful osteomyelitis in patients with SAPHO syndrome (Synovitis, Acne, Pustulosis, Hyperostosis, Osteitis) is often a problem. A 53-year-old woman had experienced palmo-plantar pustular skin lesions for four years, and in the past two years complained about progressive breath-and movement-dependent pain of the sternum. On examination she had extensive palmoplantar pustules and a painful swelling in the area of the right sternoclavicular joint. The three-phase bone scintigraphy showed a strong focal enrichment in the right sternoclavicular joint and at the transition from the manubrium to the corpus sterni suggesting active osteo-chondritis. Initially prednisolo…
