Surveillance of methicillin-resistant Staphylococcus aureus, multidrug-resistant Gram-negatives and fungi colonization in the Neonatal Intensive Care…
2015
Introduction Multidrug-resistant organisms are a serious public health problem, particularly in critical hospital wards such as the Neonatal Intensive Care Units (NICUs). Hospitalized neonates are at high risk for healthcare-associated infections leading to higher morbidity and mortality rates, because of their poor immune defences, frequent exposure to antibiotics, invasive procedures and contacts with healthcare-workers. Our study aimed to evaluate the prevalence of colonization by methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Gram-negatives (MDRGNs) and fungi in the five NICUs of the city of Palermo. Methods From February 2014 to January 2015, an active surveill…

Deep Gaussian processes for biogeophysical parameter retrieval and model inversion
2020
Parameter retrieval and model inversion are key problems in remote sensing and Earth observation. Currently, different approximations exist: a direct, yet costly, inversion of radiative transfer models (RTMs); the statistical inversion with in situ data that often results in problems with extrapolation outside the study area; and the most widely adopted hybrid modeling by which statistical models, mostly nonlinear and non-parametric machine learning algorithms, are applied to invert RTM simulations. We will focus on the latter. Among the different existing algorithms, in the last decade kernel based methods, and Gaussian Processes (GPs) in particular, have provided useful and informative so…
FORMULATION OF LIME MORTARS BASED ON NATURAL FIBERS AND WASTE MATERIALS FOR MORE SUSTAINABLE BUILDINGS
2019
Nowadays sustainability is one of the main concept in building construction, both considering energy saving buildings and life cycle assessment of building materials. According to these considerations, in this work the use of recycled and waste materials to produce a binder and the use of a natural fiber as reinforcement are investigated to obtain a sustainable mortar. Particularly, lime is obtained by kilning waste marble slurry from marbles quarries in western Sicily; pozzolanic aggregate is obtained by grinding glass powder from urban waste collection; natural fibers come from a widespread grass: Ampelodesmos Mauritanicus also known as diss. Scanning electron microscopy and helium picnom…
Monitoring 10-m LST from the Combination MODIS/Sentinel-2, Validation in a High Contrast Semi-Arid Agroecosystem
2020
Downscaling techniques offer a solution to the lack of high-resolution satellite Thermal InfraRed (TIR) data and can bridge the gap until operational TIR missions accomplishing spatio-temporal requirements are available. These techniques are generally based on the Visible Near InfraRed (VNIR)-TIR variable relations at a coarse spatial resolution, and the assumption that the relationship between spectral bands is independent of the spatial resolution. In this work, we adopted a previous downscaling method and introduced some adjustments to the original formulation to improve the model performance. Maps of Land Surface Temperature (LST) with 10-m spatial resolution were obtained as output fro…
Fennel waste-based films suitable for protecting cultivations.
2007
Biodegradable, flexible, and moisture-resistant films were obtained by recycling fennel waste and adding to fennel homogenates the bean protein phaseolin that was modified or not modified by the enzyme transglutaminase. All films were analyzed for their morphology, mechanical properties, water vapor permeability, and susceptibility to biodegradation under soil-like conditions. Our experiments showed that transglutaminase treatment of the phaseolin-containing fennel waste homogenates allowed us to obtain films comparable in their mechanical properties and water vapor permeability to the commercial films Ecoflex and Mater-Bi. Furthermore, biodegradability tests demonstrated that the presence …
Naevus Comedonicus Immunohistochemical Features in Two Cases
2003
Sir, Naevus comedonicus was first described by Kofmann in 1895 (1). It was arranged in groups or linear patterns along Blaschko’s line and located on the face, neck, upper arms, chest and abdomen. It has been well documented that naevus comedonicus occurs as a single entity but occasionally in association with other disorders. The objective of this study was to analyse the clinical and immunohistochemical features of two patients with extensive naevus comedonicus arranged in groups and linear patterns without non-cutaneous abnormalities.
Alpha-1 antitrypsin deficiency: outstanding questions and future directions
2018
BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) is a rare hereditary condition that leads to decreased circulating alpha-1 antitrypsin (AAT) levels, significantly increasing the risk of serious lung and/or liver disease in children and adults, in which some aspects remain unresolved. METHODS: In this review, we summarise and update current knowledge on alpha-1 antitrypsin deficiency in order to identify and discuss areas of controversy and formulate questions that need further research. RESULTS: 1) AATD is a highly underdiagnosed condition. Over 120,000 European individuals are estimated to have severe AATD and more than 90% of them are underdiagnosed. CONCLUSIONS: 2) Several clinical and…
