Interacting processes in protein coagulation
1999
A strong interest is currently focused on protein self-association and deposit. This usually involves conformational changes of the entire protein or of a fragment. It can occur even at low concentrations and is responsible for pathologies such as systemic amyloidosis, Alzheimer's and Prion diseases, and other neurodegenerative pathologies. Readily available proteins, exhibiting at low concentration self-association properties related to conformational changes, offer very convenient model systems capable of providing insight into this class of problems. Here we report experiments on bovine serum albumin, showing that the process of conformational change of this protein towards an intermedia…
Il consenso informato ai trattamenti sanitari sui minori e decisioni di fine vita. Riflessioni comparatistiche
2019
The essay deals with the informed consent to allow or to refuse medical treatment for pediatric patients, in a comparative law perspective. The first part focuses on the principle of personal autonomy and the rights to health and to life for patiens who lack capacity, as enshrined in Italian legislation. In determining care and treatment in relation to their child, parents have to take into account the physical and mental well-being, life and dignity of the person, as fully as possible (art. 3, L. 219/2017). The second part of the paper investigates the consequences of parents' refusal to interrupt or continue life-sustaining treatment in relation to infants suffering from serious and incur…
Qualitative analysis by experts of the essential elements of the nursing practice environments proposed by the TOP10 questionnaire of assessment of e…
2020
Background: A short TOP10 scale based on the Practice Environment Scale-Nursing Work Index questionnaire measures the characteristics of nursing work environments. Positive environments result in better quality care and health outcomes. Objective: To identify a small number of core elements that would facilitate more effective interventions by nurse managers, and compare them with the essential elements proposed by the TOP10. Method: Qualitative research by a nominal group of eight experts. The content analysis was combined with descriptive data. Results: Ten most important items were selected and analyzed by the expert group. A high level of consensus in four items (2, 15, 20, 31) and an a…
Mediterranean bioconstructions along the Italian coast
2018
Marine bioconstructions are biodiversity-rich, three-dimensional biogenic structures, regulating key ecological functions of benthic ecosystems worldwide. Tropical coral reefs are outstanding for their beauty, diversity and complexity, but analogous types of bioconstructions are also present in temperate seas. The main bioconstructions in the Mediterranean Sea are represented by coralligenous formations, vermetid reefs, deep-sea cold-water corals, Lithophyllum byssoides trottoirs, coral banks formed by the shallow-water corals Cladocora caespitosa or Astroides calycularis, and sabellariid or serpulid worm reefs. Bioconstructions change the morphological and chemicophysical features of prima…
Organochlorine Pesticides and Polychlorinated Biphenyl Congeners in LannerFalco biarmicus feldeggiiSchlegel Chicks and Lanner Prey in Sicily, Italy
2008
This paper reports on research conducted to elucidate the risk posed to the Sicilian population of the endangered lanner falcon Falco biarmicus feldeggii Schlegel by organochlorine (OC) pesticides and polychlorinated biphenyls (PCBs), as part of a wider study on contaminant risk to the lanner. Seventeen lanner nest sites were studied in northern and central Sicily. Sampling (in 2005) and analysis were carried out for selected OC pesticides and PCB congeners in lanner chick blood (15 chicks from 6 nest sites) and in two of the main lanner prey species, magpie Pica pica (36 individuals from 6 lanner nest sites) and rock dove Columba livia (10 individuals from 2 lanner nest sites). No OC and P…
Landscape-scale Spatial Distribution of the Lanner Falcon (Falco biarmicus feldeggii) Breeding Population in Italy
2008
Falco biarmicus feldeggii is one of the most threatened taxa in Europe. Its global population is estimated at a few hundred pairs unequally scattered in a vast and fragmented area stretching from Sicily to the Caspian Sea. Most recent counts showed that Italy hosts a large part (>25%) of the whole population. Consequently, Italian authorities promoted a national action plan. In this framework, we carried out the first national survey for the Lanner Falcon in Italy (2003-2004). Our study area covered the whole breeding range, i.e., Sicily and the Italian peninsula (n = 2909 cells 10 × 10 km). When possible, we considered also additional information from previous regional investigations (1993…
Vincenzo Consolo. Tra romanzo ed antiromanzo negli ultimi decenni del Novecento.
2010
La pluralità di forme testuali e di registri linguistici, nel laboratorio inventivo di Consolo,compone un tessuto sperimentale capace di erodere il codice mimetico del romanzo realista.La mistione di codici figurativi,poetici e teatrali -in specie della tragedia antica-, in tanti romanzi, sostiene una peculiare semiosi narrativa. Gli elementi più significativi risiedono in forme antiromanzesche e in uno stile metaforico denso di tensioni conoscitive.

Motivos para el consumo de cibersexo y su relación con el grado de severidad
2018
La práctica del cibersexo es un comportamiento frecuente que puede desembocar en un patrón de consumo compulsivo, incontrolado y asociado a un deterioro funcional en diversos ámbitos (adicción al cibersexo). Por tanto, conocer los motivos que explicarían que una persona realice esta conducta (de modo recreativo o patológico) es prioritario. Así, este trabajo se plantea el objetivo de analizar la prevalencia de distintos motivos para el consumo de cibersexo, las diferencias en función del género y el vínculo entre estos motivos y los síntomas de consumo problemático. Tomando una muestra de 400 jóvenes (50% hombres) de entre 18-30 años (M=22.2), se constata que las motivaciones más frecuentes…
Estimates, trends, and drivers of the global burden of type 2 diabetes attributable to PM2·5 air pollution, 1990–2019: an analysis of data from the G…
2022
Background: Experimental and epidemiological studies indicate an association between exposure to particulate matter (PM) air pollution and increased risk of type 2 diabetes. In view of the high and increasing prevalence of diabetes, we aimed to quantify the burden of type 2 diabetes attributable to PM2·5 originating from ambient and household air pollution.Methods: We systematically compiled all relevant cohort and case-control studies assessing the effect of exposure to household and ambient fine particulate matter (PM2·5) air pollution on type 2 diabetes incidence and mortality. We derived an exposure–response curve from the extracted relative risk estimates using the MR-BRT (meta-regress…
