Environmental and biological factors are joint drivers of mercury biomagnification in subarctic lake food webs along a climate and productivity gradi…
2021
Subarctic lakes are getting warmer and more productive due to the joint effects of climate change and intensive land-use practices (e.g. forest clear-cutting and peatland ditching), processes that potentially increase leaching of peat- and soil-stored mercury into lake ecosystems. We sampled biotic communities from primary producers (algae) to top consumers (piscivorous fish), in 19 subarctic lakes situated on a latitudinal (69.0-66.5 degrees N), climatic (+3.2 degrees C temperature and +30% precipitation from north to south) and catchment land-use (pristine to intensive forestry areas) gradient. We first tested how the joint effects of climate and productivity influence mercury biomagnific…
Incidence of venous thromboembolism in patients undergoing thoracotomy for lung cancer
2008
Limited information exists on the incidence of symptomatic venous thromboembolism (vTE) in patients undergoing chest surgery for lung cancer. Several factors increase the thromboembolic risk in patients undergoing surgery for lung cancer: the intrinsic procoagulant effect of cancer,extensive surgical intervention, dependent limb position in the operating room, and vessel injury consequent to the operation. Furthermore,these patients might be especially vulnerable to pulmonary embolism (PE) because of the loss of lung tissue and the presence of chronic obstructive pulmonary disease and cardiovascular diseases caused by smoking.t Older studies found a very high incidence of thromboembolic eve…
Loss of the preconditioning effect of rosuvastatin during sustained therapy: a human in vivo study
2011
Studies have demonstrated that the acute administration of 3-hydroxy-3 methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors has protective effects in the setting of ischemia-reperfusion (IR). Previously, we demonstrated that a single dose of rosuvastatin prevented IR-induced endothelial dysfunction in humans through a cyclooxygenase-2-dependent mechanism. Whether the chronic administration of HMG-CoA reductase inhibitors provides similar protection remains controversial and is unknown in humans. Eighteen male volunteers were randomized to receive a single dose of rosuvastatin (20 mg) or placebo. Twenty-four hours later, endothelium-dependent, radial artery flow-mediated dilation (FMD) w…
IL CONTROLLO GIUDIZIARIO “VOLONTARIO”: UNA MODERNA “MESSA ALLA PROVA” AZIENDALE PER UNA TUTELA RECUPERATORIA CONTRO LE INFILTRAZIONI MAFIOSE
2019
Il Controllo giudiziario "volontario" costituisce la novità più "innovativa" del codice antimafia del 2017. E', infatti, l'unica di misura do prevenzione applicata su istanza della parte privata, posta a chiusura della parte del codice dedicata alle forme di intervento patrimoniale diverse dalla confisca
Minori Stranieri Non Accompagnati e Tutore Volontario: verso una Pedagogia dell’Accoglienza. L’esperienza del territorio palermitano
2020
Il flusso migratorio dei Minori Stranieri non Accompagnati è un fenomeno globale e soprattutto negli ultimi anni ha evidenziato la necessità di sviluppare e creare dei modelli inclusivi che si basino tanto sull’implementazione di norme regolamentarie quanto sull’intervento civico-sociale. La presa in carica del minore si è concretizzata nella creazione della figura del Tutore Volontario. Attraverso l’analisi dei bisogni del minore e dell’istanza pedagogica del Tutore, si analizza la formazione del Tutore Volontario in relazione all’esperienza realizzata a Palermo dal Garante dell’Infanzia e dell’Adolescenza del Comune di Palermo. The migratory flow of unaccompanied foreign minors is a globa…
Validation of the Western Ontario and McMaster Universities Osteoarthritis Index in Patients Having Undergone Ankle Fracture Surgery
2019
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a patient-reported outcome measure (PROM) that is widely used to evaluate the pain, stiffness, and physical function of patients with osteoarthritis of the hip and knee. Although the WOMAC has also been used for patients after foot and ankle surgery, it has not been validated for this purpose. A total of 130 patients with surgically treated ankle fractures completed the WOMAC, Visual Analogue Scale Foot and Ankle (VAS FA), Lower Extremity Functional Scale (LEFS), 15D Health-Related Quality-of-Life Questionnaire (15D), and Visual Analog Scale for General Health (VAS general health) after foot and ankle surgery. The…
A return to humane medicine: Osler's legacy.
2017
Sir William Osler is celebrated today not only for his contributions to the advancement of medical education, but also for the humanism he brought to the practice of medicine. He was a doctor whose bedside skills and manners were emulated, and can legitimately be called an infectious diseases specialist. Nonetheless, he was also a humanist in the broader sense of the term, a student of human affairs and human nature, who emphasised compassion for the individual. To what extent, if any, are today's challenges influenced by departures from the paradigms created by Osler? In this paper we sought to ascertain whether such a tradition is still relevant to current practice and may foster a new pe…
Distribution and characteristics of Listeria monocytogenes isolates from surface waters of the South Nation River Watershed, Ontario, Canada
2007
ABSTRACT Listeria monocytogenes is a facultative intracellular pathogen thought to be widely distributed in the environment. We investigated the prevalence and characteristics of L. monocytogenes isolates from surface waters derived from catchments within the South Nation River watershed (Ontario, Canada). This watershed is dominated by urban and rural development, livestock and crop production, and wildlife habitats. From June to November 2005, a total of 314 surface water samples were collected biweekly from 22 discrete sampling sites characterized by various upstream land uses. Presumptive Listeria spp. were isolated using a selective enrichment and isolation procedure, and 75 L. monocyt…
FORME ASIMMETRICHE E NULLITA' SELETTIVE PER I CONTRATTI RELATIVI ALLA PRESTAZIONE DEI SERVIZI DI INVESTIMENTO
2020
The paper focuses on some critical aspects related to the issue of formalism in investment contracts; it focuses in particular on the inconsistencies arising from the recent opinion expressed by the United Sections of the Court of Cassation as regard to the “selective” nullity
Minori migranti soli e bisogno di riconoscimento: la tutela legale come atto dell’aver cura.
2021
Il presente contributo propone una riflessione pedagogica sulla relazione educativa tra la figura del tutore legale volontario, istituito con la Legge n. 47 del 2017 e l’adolescente migrante “solo”, accolto nel Sistema di Accoglienza e Integrazione (SAI). Partendo dall’esperienza educativa della tutorialità, assunta nella presa in carico degli adolescenti soli come una nuova forma di affiancamento e pratica dell’aver cura del mondo interiore ed esperienziale del minore, che presenta aspetti linguistici e culturali differenti, si cercherà di far emergere i tratti essenziali che costituiscono il suo bisogno di essere riconosciuto come persona. Quella dell'adolescente migrante solo è un’esiste…
