Clinical Recommendation Radical Trachelectomy for Fertility Preservation in Patients With Early-Stage Cervical Cancer
2012
Radical trachelectomy (RT) is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. In the current review, indications, development of the procedure, technical aspects, preoperative and postoperative management, and oncological, fertility, and obstetric outcomes are discussed and studied with respect to whether the procedure is performed abdominally or vaginally. Complications of RT, staging, and more conservative alternatives to RT are discussed as well. A systematic MEDLINE search was performed, which yielded 218 articles, of which 75 were selected for further analysis based on the number of pat…
Innovation in lighting for enhancing the appreciation and preservation of archaeological heritage
2014
Abstract The cultural content of ancient sites highlights the importance of light, which is an essential tool for the correct appreciation of the historical value and memory of cultural heritage. This should be a new way to highlight significance of fragments in compliance of the surrounding, which has not the same characteristics, to signal a visual path, creating itineraries that involve the context. Light plays a very important role in creating emotion, suggestion, evocation and supporting the visitor experience. Innovative technological solutions should be designed taking into account the kind of landscape and morphological characteristics of the site. This paper presents the study of a…
Il patrimonio delle ville di Bagheria, fra storia, conservazione e valorizzazione
2016
Il volume di M.A. Giusti (a cura di), Ville lucchesi, d’Italia, del mondo Conoscenza e cura delle dimore di campagna e dei loro giardini, pubblicato a Lucca nel 2016, rappresenta il primo studio che indaga in maniera completa la particolare tipologia della villa e il suo contesto, non solo in un ambito italiano, ma nel mondo. Assieme alle ville lucchesi, che con l’associazione Ville e Palazzi di Lucca ha promosso l’iniziativa editoriale, sono indagate le ville Venete, Torinesi, del Lazio, quelle Medicee, Vesuviane e quelle esistenti nel territorio del comune di Bagheria. Con il volume della Giusti, le ville barocche e tardo barocche di Bagheria vengono inserite nel vasto panorama culturale …
Stability of the lipid fraction of milk‐based infant formulas during storage
2005
A study is made of the effects of storage (time and temperature) on the lipid fraction of four milk-based adapted infant formulas with basically the same composition, though differing in the iron salt added (lactate or sulfate) and/or the vitamin E source (a-tocopherol or α-tocopherol acetate). Peroxide value, hydroperoxide C 18 percentage and thiobarbituric acid-reactive substance (TBARS) content were used as indicators of lipid peroxidation. Fat contents remained stable throughout storage. Peroxide values increased from the first storage month and were affected by storage time, although they exhibited irregular behavior. Storage time and temperature affected hydroperoxide percentage, whic…
Effects of pulsed electric fields on water-soluble vitamins and ACE inhibitory peptides added to a mixed orange juice and milk beverage
2007
Abstract The effects of pulsed electric fields technology (15–40 kV/cm; 0–700 μs) and thermal processing (84 °C and 95 °C, 15–120 s) were studied on an orange juice and milk mixed beverage fortified with water-soluble vitamins (biotin, folic acid, pantothenic acid and riboflavin) and angiotensin-I-converting enzyme (ACE) inhibitory peptides. The evaluation of the technologies was carried out from two points of view: effect of treatments and effect of storage (4 °C, 81 days). The results confirmed the stability of the vitamins and the ACE inhibitory activity after the PEF treatment and during storage.
Influence of storage and in vitro gastrointestinal digestion on totqal antioxidant capacity of fruit beverages
2011
Eight fruit beverages containing grape, orange and apricot, with/without iron and/or zinc and with/without milk added were analyzed for total antioxidant capacity (ORAC and TEAC methods), ascorbic acid content, and total polyphenols. The influence of cold storage (2-4 degrees C) during the product shelf-life (135 days) and antioxidant capacity after an in vitro gastrointestinal digestion were evaluated. Antioxidant capacity for all beverages together increased significantly (p < 0.05) at the end of storage (16.4% and 12.8% for ORAC and TEAC, respectively), whereas ascorbic acid remained stable. Regarding in vitro digestion, antioxidant values of bioaccessible fractions of fruit beverages in…
Combined effect of natural antioxidants and antimicrobial compounds during refrigerated storage of nitrite-free frankfurter-type sausage.
2019
Abstract The effects of nisin (200 and 400 ppm), e-polylysine (0.1 and 0.2%) and chitosan (0.5 and 1%) in combination with a Mixed Extract (green tea, stinging nettle and olive leaves extracts) on the physicochemical, microbiological characteristics, fatty acid composition and sensory attributes of the nitrite-free frankfurter-type sausages were assessed during 45 days of storage. The results revealed no significant differences on moisture, fat, protein, ash, salt and water activity (aw) among treatments. 1% Chitosan + Mixed Extract sausages displayed the lowest thiobarbituric acid reactive substances (TBARS) and total volatile nitrogen (TVN) values compared to Control after 45 days of refr…
Preparation of fungal conidia impacts their susceptibility to inactivation by ethanol vapours.
2009
Abstract A common protocol employed for the preparation of conidia employs flooding a fungal colony grown on semi-solid media under optimum conditions with an aqueous solution. In contrast, conidia produced in a natural environment are usually not hydrated when disseminated in air and can be produced under water stress. In order to simulate the latter conditions, cultures were grown at different water activities and conidia were dry-harvested on the lid by turning the dishes upside-down then gently tapping the bottom of the box. This study aimed at assessing the effect of the preparation of fungal conidia on their inactivation by ethanol vapours. Firstly ethanol vapours (either 0.30 or 0.45…
Vacuum impregnation as a tool to introduce biopreservatives in gilthead sea bream fillets (Sparus aurata)
2015
Abstract The aim of this study was to determine the possible technological uses of biopreservation and vacuum impregnation techniques to extend shelf life of gilthead sea bream fillets. Two impregnation media were studied: a solution containing lactic acid bacteria (LAB) and a nisin solution. Vacuum impregnation was carried out at 4 °C. Fillets were immersed in a vessel containing the impregnation solution and vacuum was applied during 5 min. After this time atmospheric pressure was restored leaving samples under the liquid for 5 min more. Weight gain, physico-chemical properties (moisture, pH, water activity and TVBN), color and microbiological counts were studied during 15 days of storage…
Thermo-hygrometry and IAQ Related Measurements of the Indoor Physical Conditions of Exhibition Halls for Complying International Rules and Standards
2018
Off-line methods for detecting the indoor physical parameters of museums are important tools in order of continuously monitoring the conditions at which works of art are exposed. These conditions, in fact, are mandatory established by several rules and technical standards aimed at preserving the specific artifacts. Moreover, indoor microclimate parameters must also take into account the comfort conditions for visiting people. Both the above-cited requirements suggest to perform the indoor monitoring with equipment visually low impacting. In this paper, some examples of visually low impacting off-line monitoring methods, applied to three artifacts displayed in the “Museo Regionale” of Palerm…
