Phenazine antibiotics produced by fluorescent pseudomonads contribute to natural soil suppressiveness to Fusarium wilt

2009

Natural disease-suppressive soils provide an untapped resource for the discovery of novel beneficial microorganisms and traits. For most suppressive soils, however, the consortia of microorganisms and mechanisms involved in pathogen control are unknown. To date, soil suppressiveness to Fusarium wilt disease has been ascribed to carbon and iron competition between pathogenic Fusarium oxysporum and resident non-pathogenic F. oxysporum and fluorescent pseudomonads. In this study, the role of bacterial antibiosis in Fusarium wilt suppressiveness was assessed by comparing the densities, diversity and activity of fluorescent Pseudomonas species producing 2,4-diacetylphloroglucinol (DAPG) (phlD+) …

Infrastrutture e paesaggio nella "città in estensione"

2017

L’esperienza didattica e di ricerca presentata nel saggio prende le mosse dall’attivazione di un laboratorio di laurea magistrale in Progettazione Architettonica diretto dal prof. Palazzotto e sviluppato nell’ambito del corso di laurea in Architettura dell’omonimo Dipartimento presso l’Università degli Studi di Palermo. Il laboratorio ha visto la partecipazione complessiva di 11 laureandi, che hanno esitato le proprie tesi negli anni compresi tra il 2013 e il 2015. Il laboratorio di laurea, facendo propria l’idea di “città-campagna” avanzata da Giuseppe Samonà nel 1976 – che porta con sé un esplicito riferimento a identità formali e spaziali specifiche intese a conferire allʼambito della ca…

Computational modeling of molecularly imprinted polymers as a green approach to the development of novel analytical sorbents

2018

Abstract The development of novel molecularly imprinted polymers (MIP) sorbents for specific chemical compounds require a lot of tedious and time-consuming laboratory work. Significant quantities of solvents and reagents are consumed in the course of the verification of appropriate configurations of polymerization reagents. Implementation of molecular modeling in the MIP sorbent development process appears to provide a solution to this problem. Appropriate simulations and computations facilitate the determination of the nature of interaction between the reagents and thus the selection of the best configuration of chemicals for the preparation of the sorbent. The article presents literature …

Clinical manifestations of cancer in patients with acute pulmonary embolism

2023

Background Neoplasmatic disease increases the risk of acute pulmonary embolism (APE) by different pathophysiological mechanisms that favor thrombosis in patients with cancer. Recently, the role of cancer (active and occult) in the prevalence of venous thromboembolism has been discussed more thoroughly in the subject literature. Material Medical records of 366 consecutive patients with a diagnosis of APE (aged: mean = 65.0 ± 16.6, median = 68, range = 19–94; men = 41%/women = 59%) were collected with a wide range of demographic data, medical history of coexisting diseases, computer examination, and laboratory tests. Methods The APE patients were analyzed in two groups: negative cancer cases …

Implementació i avaluació de codis QR en laboratoris docents d’enginyeria química

2014

Els codis QR (Quick Response) són codis de barra àmpliament utilitzats en aplicacions comercials i de màrqueting per incloure enllaços a pàgines web, entre altres coses. En l'actualitat un gran nombre de dispositius electrònics com telèfons intel·ligents o tauletes compten amb aplicacions capaces de capturar aquesta informació, permetent al seu usuari emmagatzemar-la i compartir-la amb altres usuaris. Hi ha alguns exemples de la seva aplicació en l'educació, encara que no s'han trobat exemples en l'àrea d'Enginyeria Química. En aquest context, el treball que es presenta és la implantació i avaluació de codis QR en laboratoris docents d'Enginyeria Química amb accés a contingut docent multimè…

Criticità della tutela dei dati scientifici nel regolamento sui nuovi alimenti anche alla luce della disciplina in materia di benessere degli animali

2021

Il regolamento (UE) 2283/2015 sui novel food rappresenta un’evoluzione nella protezione dei dati scientifici relativi ai nuovi prodotti alimentari. La normativa, sviluppata sul modello offerto dal regolamento (UE) 1924/2006 in materia di indicazioni nutrizionali e sulla salute, garantisce una protezione quinquennale dei dati scienti ci e delle prove pro- dotte dal richiedente in sede di domanda di autorizzazione di un nuovo prodotto ex art. 10 del regolamento (UE) 2283/2015. La previsione di un termine quinquennale di tutela se, secondo taluni, può risultare troppo breve per rappresentare un vero incentivo per compiere investimenti in ricerca e sviluppo da parte delle imprese; d’altra part…

Flow characteristics of a channelized debris-flow and implications in numerical modelling: a study case

2012

As it is known, debris flows are characterized by extreme propagation rapidity and by the ability to move high quantity of fluid mass. Furthermore, debris flows are fluid enough to travel long distances and, thus, to cause damage in vast areas, even far from the trigger ones. Debris-flow runout estimations are important for the delineation of potentially hazardous areas. Especially in recent years, several researches have been conducted in order to define predicitive models. But, existing runout estimation methods need input parameters that can be difficult to estimate. Recent advances in theory and in experimental research have allowed the assessment of the physics of the debris flows. On …

Defensive behavior in healthcare: the role of organizational factors

Defensive medicine occurs when a healthcare practitioner performs treatment or procedure to avoid exposure to malpractice litigation. Being the consequences of such a behavior nefarious both in terms of patient care, healthcare operations and cost, much has been done in terms of research and practice with the aim to reduce the likelihood of its occurrence. Because defensive medicine is strictly related to the doctor perception of the risk of litigation and its legal repercussions, in the last years, jurisprudence and insurance contract studies in healthcare focused on this topic, as well as national laws have been introduced with the goal of contrasting it. This paper argues and demonstrate…

Dreams and Trauma Changes in the Manifest Dreams in Psychoanalytic Treatments - A Psychoanalytic Outcome Measure.

2021

Although psychoanalysts are interested in symptom reduction as an outcome, they are looking for instruments to measure sustaining changes in the unconscious mental functioning. In this article it is discussed that conceptually well-founded transformation of manifest dreams analyzed with precise empirical methods could be considered as a promising indicator for such therapeutic changes. We are summarizing a dream generation model by Moser and von Zeppelin which has integrated a large interdisciplinary knowledge base of contemporary dream and sleep research. Based on this model the authors have developed a valid and reliable coding system for analyzing manifest dreams, the Zurich Dream Proces…

Leishmania tarentolae and Leishmania infantum in humans, dogs and cats in the Pelagie archipelago, southern Italy.

2021

Visceral leishmaniasis (VL) caused by Leishmania infantum is endemic in the Mediterranean basin with most of the infected human patients remaining asymptomatic. Recently, the saurian-associated Leishmania tarentolae was detected in human blood donors and in sheltered dogs. The circulation of L. infantum and L. tarentolae was investigated in humans, dogs and cats living in the Pelagie islands (Sicily, Italy) by multiple serological and molecular testing. Human serum samples (n = 346) were tested to assess the exposure to L. infantum by immunofluorescence antibody test (IFAT), enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) and to L. tarentolae by IFAT. Meanwhile, sera from do…
