Determination of heavy metal content and lipid profiles in mussel extracts from two sites on the moroccan atlantic coast and evaluation of their biol…
2012
Mussels may concentrate pollutants, with possibly significant side effects on human health. Therefore, mussels (Mytilus galloprovincialis) from two sites of the Moroccan Atlantic coast (Jorf Lasfar [JL], an industrial site, and Oualidia [OL], a vegetable-growing area), were subjected to biochemical analyses to quantify the presence of heavy metals (Cd, Cr, and Pb) and to establish the lipid profile: fatty acid, cholesterol, oxysterol, phytosterol and phospholipid content. In addition, mussel lipid extracts known to accumulate numerous toxic components were tested on murine pancreatic β-cells (MIN6), and their biological activities were measured with various flow cytometric and biochemical m…
Notes on the karyology, genetics and ecology of Genista sect. Voglera in Sicily
2012
To investigate the biosystematic and genetic relationships among Sicilian species of Genista sect. Voglera, four populations of three species, Genista aristata C. Presl, Genista cupanii Guss., and Genista madoniensis Raimondo, have been studied. Genista madoniensis is tetraploid, with a chromosome number of 2n = 48, as are the other two species. An isozyme study showed that G. madoniensis is taxonomically closer to G. aristata than to G. cupanii, the latter possessing four unique alleles. The results are discussed in the context of the ecological characteristics of each species.
Insights into the annotated genome sequence of Methanoculleus bourgensis MS2(T), related to dominant methanogens in biogas-producing plants
2014
The final step of the biogas production process, the methanogenesis, is frequently dominated by members of the genus Methanoculleus. In particular, the species Methanoculleus bourgensis was identified to play a role in different biogas reactor systems. The genome of the type strain M. bourgensis MS2(T), originally isolated from a sewage sludge digestor, was completely sequenced to analyze putative adaptive genome features conferring competitiveness within biogas reactor environments to the strain. Sequencing and assembly of the M. bourgensis MS2(T) genome yielded a chromosome with a size of 2,789,773 bp. Comparative analysis of M. bourgensis MS2(T) and Methanoculleus marisnigri JR1 revealed…
HL7v3 CDA Rel.2 Patient Summary and Chronic Care Model: Localization experience and GP/HS Integration Project
2010
The localization experience for the Patient Summary, based on the Health Level Seven Version 3 (HL7v3) Clinical Document Architecture, Release 2 (CDA Rel.2), is presented. An overview of the Chronic Care Model (CCM) is introduced with particular attention to the clinical information systems, in order to organize patient and population clinical data by sharing information among healthcare providers in management of chronic diseases. We propose, as case study, a project for the integration of various services for General Practitioners (GP) and Hospital Specialists (HS), accessing the Electronic Health Record (EHR), implementing the Patient Summary and managing the exchange of Chronic Care med…
Production of spray-dried proanthocyanidin-rich cinnamon (Cinnamomum zeylanicum) extract as a potential functional ingredient: Improvement of stabili…
2018
International audience; Cinnamon proanthocyanidins present important biological properties. However, these molecules are unstable and possess an astringent taste, which can make their ingestion difficult. In this context, entrapment by spray-drying technology may be used to produce a concentrated extract with improved stability and reduced astringency. Thus, this work aimed to prepare spray-dried microparticles loaded with a proanthocyanidin-rich cinnamon (Cinnamomum zeylanicum) extract (PRCE), immobilized in a maltodextrin matrix. Freeze-dried samples of the extract (without the carrier) were also prepared for comparison. The particles were characterized for moisture content, water activit…
Two Latent and Two Hyperstable Polymeric Forms of Human Neuroserpin
2010
AbstractHuman neuroserpin (hNS) is a serine protease inhibitor that belongs to the serpin superfamily and is expressed in nervous tissues. The serpin fold is generally characterized by a long exposed loop, termed the reactive center loop, that acts as bait for the target protease. Intramolecular insertion of the reactive center loop into the main serpin β-sheet leads to the serpin latent form. As with other known serpins, hNS pathological mutants have been shown to accumulate as polymers composed of quasi-native protein molecules. Although hNS polymerization has been intensely studied, a general agreement about serpin polymer organization is still lacking. Here we report a biophysical chara…
The Sustainability of Reclaimed Asphalt as a Resource for Road Pavement Management through a Circular Economic Model
2019
The transition of the road engineering industry to a circular way of doing business requires more efficient and sustainable resources, energy, and waste management. The rates in which reclaimed asphalt is being recycled or reused in the asphalt mixture production process constitutes a crucial parameter in this transition. This paper aims at establishing a further step towards the combined circularity and sustainability of asphalt pavements, by introducing a framework for quantifying their Material Circularity Index. The framework is based on the methodology proposed by the Ellen MacArthur Foundation and accordingly tailored for the context of asphalt pavements. This study, thus, attempts to…
New Arrivals, Old Places: Demographic Changes and New Planning Challenges in Palermo and Naples
2008
If we look at the demographic changes in the largest cities in Southern Italy, the most significant trend is a balance between population growth and decline, affecting in particular inner urban areas, which is due to the predominance of new ethnic inhabitants. After having described these demographic changes in Naples and Palermo, the paper will include some considerations on the ‘institutional’ landscape of planning and the related policies. How do planning policies and practices face this quick change in such peripheral contexts, which are new to the phenomenon? Can the plural composition of the local society be viewed as an opportunity, and not just as a threat? The paper will use some a…
A chi si rivolgono le norme di diritto internazionale?
2023
In this chapter the traditional legal issues concerning the identification of the subjects of international law is examined according to an original perspective. First of all, the legal regimes of self-determination, minorities and national reconciliation processes are seen, as a whole; namely, as expressions of the increasing legal value of civil societies (peoples, groups) in international law. Second: the legal regime of State sovereignty is dealt with in this chapter, since sovereignty is considered as being the logical corollary of state international capacity. Third and most importantly: the legal position of individuals is not examined in general terms, but with specific regard to so…
Rethinking Civil Society in Development: Scales and Situated Hegemonies
2016
Ethnic residential segregation is often explained with the claim that ‘immigrants don’t want to integrate—they prefer to stick together with co-ethnics’. By contrast, mixed neighbourhoods are seen as crucial for achieving social cohesion. In line with spatial assimilation theory there is a normative assumption that people interact with those living nearby. From interviews on neighbourhood qualities and locations valued by Oslo residents of Turkish, Somali and Polish backgrounds, we raise questions about the validity of two assumptions: that most immigrants want to live in the same neighbourhoods as co-ethnics; and that they want to live close to co-ethnics because they do not want to integr…
