Introduction. Social Work with newcomers: entering into the field
2021
For about thirty years, Sicily has assumed the role of a gateway from Africa to Europe, acting as a bridge between cultures, ethnic groups and religions. When we talk about immigration in Sicily, therefore, we are referring to a structural reality, which the island's inhabitants have generally accepted with a sense of hospitality and openness. It is an interesting observation point from which it is possible to look at the social and political implications generated by immigration movements in the understanding of contemporary migration phenomena.
Studio dell'attività biologica di metaboliti di Citrus spp. su Ceratitis capitata
2011
La mosca mediterranea della frutta, Ceratitis capitata (Wiedemann) (Diptera Tephritidae) è uno degli insetti maggiormente dannosi a livello mondiale. In anni recenti sono state condotte numerose ricerche sui semiochimici coinvolti nelle interazioni insetto-pianta ospite, avvalendosi di studi elettrofisiologici e comportamentali, con lo scopo di utilizzare le sostanze biologicamente attive eventualmente identificate in strategie di controllo innovative e sostenibili. È noto che i limoni non sono attaccati da C. capitata, molto probabilmente a causa degli oli essenziali dell’epicarpo, tossici per altre mosche della frutta. Nel presente lavoro sono state effettuate registrazioni elettrofisiolo…
A new species within the Centaurea busambarensis complex (Asteraceae, Cardueae) from Sicily
2022
The Centaurea busambarensis group is made up by eight species endemic to Sicily. We statistically evaluated a population found on the Nebrodi Mountain (NE Sicily) to verify if the observed morphological differences with the already known taxa justified the description of a new one. It resulted in being sufficiently distinct to deserve recognition at the species level. Centaurea valdemonensis, a new species endemic to Sicily is described and illustrated here. It is confined to the Nebrodi Mountains (NE Sicily). The distinction of this taxon from the others belonging to the C. busambarensis complex has been supported with the aid of statistical analyses on morphological characters. The differ…
I musei naturalistici come presidi ambientali e culturali. L'Orto botanico di Palermo
2013
La funzione degli Orti botanici, fondamentalmente, si esplica nella conservazione, nella ricerca scientifica, nelle attività espositive ed educative. I punti di forza dell’azione sociale di questi tipi di musei deriva sia dalla capacità di produrre e diffondere la conoscenza scientifica, sia dalla ricchezza patrimoniale posseduta. Una serie di emergenze planetarie e le prospettive incerte per l’ambiente, le società, le economie di tutte le nazioni del mondo configurano lo scenario d’oggi. Questa situazione richiede la costruzione collettiva di nuove forme di sentire, pensare e agire nella ricerca di soluzione ai problemi contemporanei. Si tratta quindi, per i musei scientifici, di intrapren…
Early Treatment of Systemic Juvenile Idiopathic Arthritis with Canakinumab and Complete Remission After 2 Years of Treatment Suspension: Case Report …
2019
Systemic juvenile idiopathic arthritis (sJIA) is an autoinflammatory disease characterised by fever and arthritis. We describe the case of a 14-year-old girl hospitalised with fever associated with rash, myalgia, arthralgia and polyarticular involvement. Examinations revealed increased levels of C-reactive protein, erythrocyte sedimentation rate, ferritin, triglycerides, leukocytes, neutrophils, lactate dehydrogenase, fibrinogen, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and γ-glutamyl transferase (GGT). Bone marrow biopsy showed polyclonal leukocyte activation. A genetic study revealed a heterozygous mutation of the MEFV gene, c.442G>C (E148Q), which is typical of…
LONG-TERM EFFECT OF TILLAGE AND CROP SEQUENCE ON SOIL MICROBIAL COMMUNITY AND NITROGEN EMISSIONS IN MEDITERRANEAN ENVIRONMENT
CHEMICAL INVESTIGATION OF THE INVASIVE ALGA CAULERPA TAXIFOLIA VAR. DISTICHOPHYLLA FROM SICILIAN COASTS
2018
Biological invasions by non-indigenous species have been widely recognized among the most important threats to the integrity of Mediterranean ecosystems, often resulting in huge economic and societal impacts. The success of non-indigenous macrophytes in the new range may be due to a variety of factors such as their vegetative reproductive strategy and synthesis of toxic compounds. These toxic compounds may influence native consumers by reducing their performance with negative implications for their overall grazing activity and, ultimately, for their ability to control the spread of the invasive algae in the new area. In particular, the invasive algae Caulerpa taxifolia (Vahl) C. Agardh (Ct)…
Biodiverse green roofs in Mediterranean climate. Input and lessons learned from Germany and Switzerland
In the realm of the doctoral program in technologies for sustainability and land restoration, this thesis deepens sustainable and ecological solutions for Mediterranean environment after the German tradition and the Swiss school of green roofs for biodiversity. Specific aims were to: (1) assess the effectiveness of the existing green roofs norms in supporting biodiversity; (2) review methodologies and approaches for the implementation of biodiverse green roofs but also their application for ecological design; (3) identify habitat templates in the Mediterranean ecoregion replicable on green roofs; and (4) investigate the long term vegetation development of unmanaged green roofs in order to g…
Diet to Reduce the Metabolic Syndrome Associated with Menopause. The Logic for Olive Oil
2020
The rates of metabolic syndrome are increasing in parallel with the increasing prevalence of obesity, primarily due to its concomitant insulin resistance. This is particularly concerning for women, as the years around menopause are accompanied by an increase in visceral obesity, a strong determinant of insulin resistance. A fall in estrogens and increase in the androgen/estrogen ratio is attributed a determining role in this process, which has been confirmed in other physiological models, such as polycystic ovary syndrome. A healthy lifestyle, with special emphasis on nutrition, has been recommended as a first-line strategy in consensuses and guidelines. A consistent body of evidence has ac…
Taking the acid test: Mediterranean limpets face up to climate change
2014
Impacts of climate change involve the interactions of multiple stressors on intertidal organisms, but rarely are the impacts of these stressors examined together. Many tests are also conducted in artificial, controlled laboratory conditions, without making use of natural opportunities to test performance of organisms under different environmental stressors. Given its small tidal range, the Mediterranean Sea provides such an opportunity, with a very fine scale environmental gradient and species living very close to each other over the tidal gradient. The vertical distribution of the limpets, Patella rustica and P. caerulea overlap in Palermo, Sicily, but despite this they have different ther…
