Role of nitric oxide synthase isoforms for ophthalmic artery reactivity in mice.
2014
Abstract Nitric oxide synthases (NOS) are involved in regulation of ocular vascular tone and blood flow. While endothelial NOS (eNOS) has recently been shown to mediate endothelium-dependent vasodilation in mouse retinal arterioles, the contribution of individual NOS isoforms to vascular responses is unknown in the retrobulbar vasculature. Moreover, it is unknown whether the lack of a single NOS isoform affects neuron survival in the retina. Thus, the goal of the present study was to examine the hypothesis that the lack of individual nitric oxide synthase (NOS) isoforms affects the reactivity of mouse ophthalmic arteries and neuron density in the retinal ganglion cell (RGC) layer. Mice defi…

Monitoring the Shelf-Life of Minimally Processed Fresh-Cut Apple Slices By Physical–Chemical Analysis and Electronic Nose
2014
Fresh-cut apples, in slices or in cubes, are minimally processed products, which are currently collecting a great interest by fruit marketers for their promising diffusion. Their shelf life, from a microbiological point of view, has been fixed about 2 or 3 weeks under refrigeration. However in a few days they undergo biochemical degradations with production of off-flavors and texture breakdown. In this work, the change of aromatic fingerprint of apple slices packaged in air and in a modified atmosphere (with 100% N2) and stored at 4°C was measured, by using a commercial electronic nose. The obtained data were also compared with sensory evaluation of judge’s panel. Moreover, quality paramete…

FRUIT QUALITY EVALUATION OF FOUR LOQUAT CULTIVARS GROWN IN SICILY
2011
Chemical (soluble solids content, titratable acidity, pH), morphological (weight, longitudinal and transversal diameter, thickness of the flesh, number of seeds, peel colour), and sensorial characteristics of four loquat cultivars (‘Algerie’, ‘Claudia’, ‘Nespolone di Trabia’ and ‘Sanfilippara’) from mature, organically-grown trees in Sicily, were analysed. The determinations were carried out by traditional instrumental techniques, by a panel test and by an electronic olfactory system. A panel of 10 trained judges was used to determine intensity of some attributes in the sensory profile of the different cultivars, while the electronic olfactory system was used to identify possible difference…

Acute pneumolabyrinth: a rare complication after cochlear implantation in a patient with obstructive sleep apnoea on CPAP therapy
2023
Pneumolabyrinth is a condition characterised by the presence of air within the inner ear and is a rare complication after cochlear implant surgery. One of the causes of pneumolabyrinth may be the increase in pressure in the middle ear. The use of continuous positive airway pressure (CPAP) is an effective treatment strategy for obstructive sleep apnoea. According to a recent study, the use of CPAP should be delayed by 1 or 2 weeks in subjects undergoing middle ear surgery; however, there is currently no indication to delay the CPAP in subjects undergoing cochlear implant surgery. We report the case of a patient on CPAP who underwent left cochlear implantation and, in the early postoperative …

Clinical risk management delle infezioni nosocomiali: profili di responsabilità
2013
L’oggetto del rapporto obbligatorio tra paziente e struttura sanitaria rientra nella complessa prestazione di assistenza sanitaria. Il rapporto, nonché la responsabilità, tra ospedale e paziente, è di natura contrattuale e ad esso si fa riferimento sia in caso di inadempimento delle obbligazioni direttamente a carico della struttura (ex art. 1218 c.c.), sia in caso Di inadempimento delle prestazioni medico-professionale del sanitario (ex art. 1228 c.c.). Un’obbligazione importante a cui risponde la struttura ospedaliera è quella di garantire l’utilizzo di locali idonei sotto il profilo igienico, in quanto essa è l’ente responsabile delle infezioni nosocomiali dovute ad agenti patogeni event…
