A comparison of infestation patterns by Ixodes ticks in urban and rural populations of the Common Blackbird Turdus merula
2002
Although spatial variation in the patterns of parasite infestations among host populations may have important ecological and epidemiological consequences, the causes underlying such variation are poorly known. In the context of a long-term study on the population biology of Common Blackbirds Turdus merula , we examined the prevalence and intensity of infestation by Ixodes ticks between birds living in rural vs. urban habitats. The overall prevalence of tick infestations was significantly higher in the rural habitat where 74% of individuals ( n = 130) were infested. This result contrasted markedly with the situation in the urban habitat where less than 2% of individuals ( n = 360) carried ti…
Prevention of fungal infestation of rainbow trout (Oncorhynchus mykiss) eggs using UV irradiation of the hatching water
2013
Abstract Fungal infestation by water mold Saprolegnia spp. causes great losses in aquaculture and fish egg hatching. To find a safe and effective alternative for the fungal prevention, we studied continuous disinfection of the inlet water by UV irradiation and ozonation combined with low concentration hydrogen peroxide (H 2 O 2 ) treatments in a rainbow trout ( Oncorhynchus mykiss ) egg hatching system. High dose of UV irradiation (400 mWs/cm 2 ) of the inlet water decreased the mortality of rainbow trout eggs from the 77.3% to 14.3% in a 28 day trial. UV irradiation did not modify water quality parameters, while combination of UV irradiation and H 2 O 2 caused up to fivefold increase in th…
The development of sporangia of Phytophthora infestans
1995
The dynamics of sporulation and zoosporogenesis of Phytophthora infestans in a naturally infected crop of potato cv. Maris Bard and on potted plants of the same cultivar infected artificially with the same fungus are described. Development of sporangiophores and sporangia was synchronous after induction. Migration of several nuclei from the sporangiophore into the sporangium initial was followed by nuclear division, then by degeneration of a proportion of the nuclei. Sporangia then became deciduous, developed papillae and became able to release zoospores in rapid succession. When infected leaves were detached and transferred from the field to moist Petri dishes, sporulation was at first syn…
Relation of fruit color, elongation, hardness, and volume to the infestation of olive cultivars by the olive fruit fly, Bactrocera oleae
2012
The susceptibility of olive cultivars to the olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), has seldom been studied. This article examines factors associated with olive fruit fly infestation of 16 commonly planted Sicilian olive cultivars. Total infestation data were simultaneously correlated with categorical and quantitative factors using ordinal logistic regression. When all factors were included in the analysis, year, sampling date, cultivar, and fruit color were highly significant, but the quantitative factors fruit volume, fruit elongation, and fruit hardness were not. When the analysis was repeated excluding cultivar, all quantitative factors were significant, and e…

Variabilità dell’olio essenziale di finocchio (Foeniculum vulgare Mill.) per effetto di trattamenti agronomici
2009
Il Finocchio da seme (Foeniculum vulgare Mill.), è una specie erbacea annuale o biennale della famiglia delle Apiaceae (ex Ombrellifere), spontanea e largamente diffusa all’interno del bacino del mediterraneo, di cui si utilizzano i frutti (comunemente detti “semi”) come aromatizzanti in numerosi preparati tradizionali e come base per la preparazione di diversi composti di interesse farmaceutico ed alimentare. Il presente lavoro illustra i risultati ottenuti a seguito di un’indagine sulla composizione dell’olio essenziale di finocchio, eseguita utilizzando materiale proveniente da un triennio (2004-2006) di prove agronomiche di controllo delle infestanti svolte in ambiente mediterraneo (Cam…
Representações sociais, sens pratique, poder simbólico e o processo de construção do ser docente
2019
A partir de las elaboraciones teóricas de los fundadores del campo de investigación de las representaciones sociales, se pretende avanzar en la construcción de un diálogo entre esta teoría y la praxis social de Pierre Bourdieu, centrándose en la relación entre las representaciones sociales, la praxis sensorial (como manifestación del hábito) y el poder simbólico, dimensión ausente en el modelo moscoviciano. La base empírica a partir de la cual se desarrollan las reflexiones presentes en este artículo se apoya en investigaciones realizadas sobre el proceso de construcción del ser docente, en la realidad de algunas ciudades del nordeste brasileño. En este sentido, se destaca lo que se cree qu…
Indagini su Tuta absoluta (Lepidoptera: Gelechiidae) in Sicilia: Andamento delle infestazioni, valutazione della presenza di nemici naturali ed effet…
Tuta absoluta è stata segnalata per la prima volta in Italia nel 2008 e in Sicilia nel 2009. Le larve causano mine fogliari e gallerie nei frutti, con conseguenti ingenti danni alle coltivazioni di pomodoro. Il primo capitolo della presente tesi riguarda ricerche condotte per studiarne i livelli di infestazione, l’andamento dei voli dei maschi e rilevarne la presenza di nemici naturali viventi a carico del fitofago in condizioni naturali in un campo nel comprensorio di Naro (AG) C/da Diesi, nel 2013 e 2014. Le varietà di pomodoro utilizzate sono state “Pizzutello” e “Piccadilly”. Inoltre, durante i due anni è stato impiantato e mantenuto un allevamento di piante di pomodoro sane e infestate…
Efficacy of non-surgical periodontal treatment on patients with coronary artery disease: a meta-analysis of randomized controlled trials
2022
Coronary artery disease (CAD) is defined as one of the most common cardiovascular diseases (CVDs). Periodontitis is one of the risk factors for CAD. PubMed, Embase and Cochrane Library databases were carefully and thoroughly retrieved until October 2021. On the basis of the inclusion and exclusion criteria, eligible articles were selected strictly to identify randomized controlled trials (RCTs). Using Cochran's Q statistic, Review Manager 5.4 and Stata 16, data were extracted, and a comprehensive analysis was carried out. Six RCTs of 619 patients were included in this study, including 360 in the intervention group (IG) and 259 in the control group (CG). Meta-analysis showed significant diff…
