La rete GNSS per il posizionamento in tempo reale dell’Università di Palermo: progetto, realizzazione e primi risultati
2008
Le reti di stazioni permanenti GNSS (Global Navigational Satellite System) per il tempo reale (NRTK - Network Real Time Kinematic) rappresentano un argomento di grande interesse per la comunità scientifica per le potenziali ricadute sulle applicazioni tecnico scientifiche del posizionamento satellitare. L’articolo descrive e affronta le problematiche riscontrate nel corso dell’attività di ricerca svolta dall’Unità Operativa di Palermo nell’ambito del progetto PRIN2005 dal titolo: “Reti di stazioni permanenti GPS per il rilievo in tempo reale in impieghi di controllo e emergenza”. La ricerca è stata finalizzata alla progettazione e realizzazione di una rete di stazioni permanenti GNSS NRTK n…
Rilievo ed elaborazione di dati laser acquisiti con sistemi MMS in un parco urbano
2013
Questo articolo riassume l'esperienza acquisita tra il 2012 e il 2013 dal Dipartimento di Ingegneria Civile, Ambientale, Aerospaziale e dei Materiali dell'Università degli Studi di Palermo per l'indagine integrata del Parco Ninni Cassarà a Palermo, Italia, e la successiva sperimentazione di metodi, strumenti e tecniche basate su ricerche in corso, per quanto riguarda l'acquisizione e l'elaborazione dei dati GNSS e laser Scanner. Il lavoro è stato affrontato al fine di selezionare le tecniche meno costose e veloci da applicare in fase di acquisizione. Dopo la prima monumentazione di sedici punti di controllo distribuiti all'interno del sito e rilevati con ricevitori GNSS, la è stata pianific…
The importance of nutritional status on clinical outcomes among both ICU and Non-ICU patients with COVID-19.
2022
Background and aims: The current Covid-19 outbreak becomes a tremendous public health concern worldwide. Since a little information is available on nutritional status and its devastating effects on covid-19 complications in Iran, in the present study, we aimed to evaluate nutritional status of covid-19 population and its related factors.Methods: We performed this observational study by recruiting 400 hospitalized covid-19 subjects. Thereafter, the needed clinical and para clinical data were collected and their nutritional status was then assessed using NRS-20 02. Results: Approximately 36% of the total sample size and 100% of the ICU- admitted cases were at the severe risk of malnutrition. …

Hop-derived fraction rich in beta acids and prenylflavonoids regulates the inflammatory response in dendritic cells differently from quercetin: unvei…
2021
Dendritic cells (DCs) represent a heterogeneous family of immune cells that link innate and adaptive immunity and their activation is linked to metabolic changes that are essential to support their activity and function. Hence, targeting the metabolism of DCs represents an opportunity to modify the inflammatory and immune response. Among the natural matrices, Humulus lupulus (Hop) compounds have recently been shown to exhibit immunomodulatory and anti-inflammatory activity. This study aimed to evaluate the ability of specific Hop fractions to modulate DCs metabolism after stimulation with lipopolysaccharide (LPS) by an untargeted metabolomics approach and compare their effect with flavonol …

Nrf2-interacting nutrients and COVID-19: time for research to develop adaptation strategies
2020
AbstractThere are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of …
In vitro effect of cadmium and copper on separated blood leukocytes of Dicentrarchus labrax.
2013
The immunotoxic effects of heavy metals on blood leukocytes of sea bass (Dicentrarchus labrax) were examined. The cells, separated by a discontinuous Percoll-gradients, were exposed in vitro to various sublethal concentrations of cadmium and copper (10(-7) M, 10(-5) M, and 10(-3) M) and their immunotoxic effect was then evaluated by measuring neutral red uptake, MU assay, DNA fragmentation and Hsp70 gene expression. First of all, we demonstrated that the cells treated in vitro could incorporate Cd and Cu. A relationship between heavy metal exposure and dose-time-dependent alterations in responses of leukocytes from blood was found for both metals, but copper was more immunotoxic than cadmiu…
