Mango e avocado nuove acquisizioni sulla coltivazione in Sicilia
2020
L’incremento delle temperature rende possibile l’adattamento biologico-colturale. Le scelte varietali e le tecniche agronomiche sostenibili che stanno dietro alla diffusione di nuovi impianti. Mango e avocado sono tra le specie più interessanti nel panorama della moderna frutticoltura italiana. Di seguito si riportano alcune considerazioni sulla coltivazione.
Application of the threshold of toxicological concern (TTC) to the safety evaluation of cosmetic ingredients.
2007
The threshold of toxicological concern (TTC) has been used for the safety assessment of packaging migrants and flavouring agents that occur in food. The approach compares the estimated oral intake with a TTC value derived from chronic oral toxicity data for structurally-related compounds. Application of the TTC approach to cosmetic ingredients and impurities requires consideration of whether route-dependent differences in first-pass metabolism could affect the applicability of TTC values derived from oral data to the topical route. The physicochemical characteristics of the chemical and the pattern of cosmetic use would affect the long-term average internal dose that is compared with the re…
School Adjustments in Children with Attention Deficit Hyperactivity Disorder (ADHD): Peer Relationships, the Quality of the Student-Teacher Relations…

This study aimed to investigate how children with attention deficit hyperactivity disorder (ADHD) adjust to school when compared to typically developing students. The convenience sample consisted o...
Determination of Drug Concentrations in Serum and Dopamine Receptor Occupancy in Brain for Optimal Antipsychotic Drug Therapy
2009
Evidence has been given that antipsychotic effects of dopamine receptor antagonists are associated with 60 and 80% striatal dopamine D2 and D3 receptor occupancy. Receptor occupancy correlates well with concentrations of the antipsychotic drugs in serum or plasma, much better than the dose. The latter is consistent with weak correlations between antipsychotic dose and serum concentrations and explained by the high interindividual variabilities in drug metabolism. Using positron emission tomography (PET) for in vivo determination of dopamine receptor occupancy in conjunction with drug concentration measurements “therapeutic windows” could be calculated for the atypical antipsychotic drugs am…
Topical application of the adenosine A2Areceptor agonist CGS-21680 prevents phorbol-induced epidermal hyperplasia and inflammation in mice
2014
The nucleoside adenosine is a known regulator of immunity and inflammation that mediates, at least in part, the anti-inflammatory effect of methotrexate, an immunosuppressive agent widely used to treat autoimmune inflammatory diseases. Adenosine A2A receptors play a key role in the inhibition of the inflammatory process besides promoting wound healing. Therefore, we aimed to determine the topical effect of a selective agonist, CGS-21680, on a murine model of skin hyperplasia with a marked inflammatory component. Pretreatment with either CGS-21680 (5 μg per site) or the reference agent dexamethasone (200 μg/site) prevented the epidermal hyperplasia and inflammatory response induced by topica…
Management of oral Graft versus Host Disease with topical agents: a systematic review
2015
Background: Oral Graft-versus-Host Disease (oGvHD) is a common complication of haematopoietic stem cell transplantation. Choosing the right topical application to be used intra orally can be a challenge. Consequently, the aim of this work is to review the effectiveness and safety of topical agents currently used in the management of the inflammatory mucosal lesions encountered in oGVHD. Material and Methods: We carried out electronic searches of publications up to May 2015 of the databases Pubmed, National Library of Medicine’s Medline, Embase and the Cochrane Central Register of Controlled Clinical trials to identify potentially relevant studies (keywords: “oral”, “graft”, “versus”, “host”…
Patógenos atípicos en pacientes hospitalizados con neumonía adquirida en la comunidad: una perspectiva mundial
2018
Abstract Background Empirical antibiotic coverage for atypical pathogens in community-acquired pneumonia (CAP) has long been debated, mainly because of a lack of epidemiological data. We aimed to assess both testing for atypical pathogens and their prevalence in hospitalized patients with CAP worldwide, especially in relation with disease severity. Methods A secondary analysis of the GLIMP database, an international, multicentre, point-prevalence study of adult patients admitted for CAP in 222 hospitals across 6 continents in 2015, was performed. The study evaluated frequency of testing for atypical pathogens, including L. pneumophila, M. pneumoniae, C. pneumoniae, and their prevalence. Ris…
Materials and prognostic factors of bone regeneration in periapical surgery: a systematic review
2013
Objectives: Analyse the effectiveness of different materials and techniques used in guided tissue regeneration (GTR) applied in periapical surgery, comparing the success rate obtained in 4-wall defects and in through-and-through bone lesions as well as to establish prognostic factors. Material and Methods: A Cochrane, PubMed-MEDLINE and Scopus database search (October 2012 to March 2013) was conducted with the search terms “periapical surgery”, “surgical endodontic treatment”, “guided tissue regeneration”, “bone regeneration”, “bone grafts”, “barrier membranes” and “periapical lesions” individually and next, using the Boolean operator “AND”. The inclusion criteria were the use of GTR (bone …
EEG Microstates Analysis in Young Adults With Autism Spectrum Disorder During Resting-State
2019
Electroencephalography (EEG) is a useful tool to inspect the brain activity in resting state and allows to characterize spontaneous brain activity that is not detected when a subject is cognitively engaged. Moreover, taking advantage of the high time resolution in EEG, it is possible to perform fast topographical reference-free analysis, since different scalp potential fields correspond to changes in the underlying sources within the brain. In this study, the spontaneous EEG resting state (eyes closed) was compared between 10 young adults ages 18-30 years with autism spectrum disorder (ASD) and 13 neurotypical controls. A microstate analysis was applied, focusing on four temporal parameters…
