L’esperienza dei caregiver primari che assistono a domicilio le persone affette dalla Malattia di Alzheimer [Alzheimer's disease and caregivers experience in home care]

The aim of this study is to investigate the experience of primary caregivers (men and women) of Alzheimer Disease dementia, in order to tailor program and project to avoid care giving burden. A qualitative phenomenological method was used and the sample was defined by data saturation. Interviews were carried out and recorded in a day care Centre, transcribed verbatim. The analysis was conducted coding common themes and phrases. Six main themes emerged. Our results are similar to those existing in literature, showing care givers as individual in great danger physically and mentally. In the light of the study it is possible to tailor a nursing model in order to improve quality of life and decrease the burden of caregivers, this model should be implemented and analyzed

The MicroBioDiverSar Project: Exploring the Microbial Biodiversity in Ex Situ Collections of Sardinia

In the last decades, biodiversity preservation has gained growing attention and many strategies, laws and regulations have been enacted by governments with this purpose. The Micro-BioDiverSar (MBDS) project, the first one regarding microbiological resources, funded by the Italian Minister of Agricultural, Food and Forestry Policies (Mipaaf) through the Law 194/2015, was aimed at surveying, cataloguing, and managing the microbial resources and the related information of three Sardinian collections (Agris BNSS, Uniss, and Unica). While microorganisms were reordered and inventoried, a federated database, accessible via the web, was designed by the bioinformatician of Ospedale Policlinico San Martino of Genova, according to both international standards and laboratory needs. The resulting MBDS collection boasts a great richness of microbial resources. Indeed, over 21,000 isolates, belonging to over 200 species of bacteria, yeasts, and filamentous fungi isolated from different matrices, mainly food, of animal and vegetable origin, collected in over 50 years, were included in the database. Currently, about 2000 isolates, belonging to 150 species, are available online for both the scientific community and agri-food producers. The huge work done allowed one to know the consistency and the composition of most of the patrimony of the Sardinian microbial collections. Furthermore, the MBDS database has been proposed as a model for other Italian collections that, as the MBDS partners, are part of the Joint Research UnitMIRRI-IT Italian collections network, with the aim of overcoming fragmentation, facing sustainability challenges, and improving the quality of the management of the collections

Propagation of Policies in Rich Data Flows

Governing the life cycle of data on the web is a challenging issue for organisations and users. Data is distributed under certain policies that determine what actions are allowed and in which circumstances. Assessing what policies propagate to the output of a process is one crucial problem. Having a description of policies and data flow steps implies a huge number of propagation rules to be specified and computed (number of policies times number of actions). In this paper we provide a method to obtain an abstraction that allows to reduce the number of rules significantly. We use the Datanode ontology, a hierarchical organisation of the possible relations between data objects, to compact the knowledge base to a set of more abstract rules. After giving a definition of Policy Propagation Rule, we show (1) a methodology to abstract policy propagation rules based on an ontology, (2) how effective this methodology is when using the Datanode ontology, (3) how this ontology can evolve in order to better represent the behaviour of policy propagation rules

Evaluation in vitro et in vivo des proprietes anthelminthiques de feuilles de Spondias mombin sur Haemonchus contortus des ovins djallonke

Depuis longtemps, la lutte contre les maladies animales s’est faite avec l’utilisation des molécules chimiques de synthèse. Cette lutte chimique est à l’origine du développement de résistance de certains agents pathogènes. Face à cette contrainte, de nouvelles méthodes de lutte sont envisagées. La présente étude se propose d’évaluer in vitro et in vivo, les propriétés anthelminthiques de Spondias mombin sur Haemonchus contortus chez les ovins Djallonké. Des tests biologiques des extraits éthanoliques et méthanoliques de la plante ont été effectués sur les larves L3 et sur les vers adultes de H contortus. Pour les essais in vivo, trois lots de brebis parasitées sont constitués : Témoin sans traitement; Lot 1 et Lot 2 recevant respectivement 1,45g et 2,9g /kg/animal de poudre de feuilles de S. mombin pendant trois jours. Les tests in vitro ont montré des valeurs significatives (p < 0,01) de la capacité des extraits de S. mombin à inhiber la migration des larves L3 (45 à 80 %) et à réduire la motilité des vers adultes après 30 heures d’exposition (77 à 100 %), comparativement au témoin de référence négatif (PBS). L’activité antiparasitaire des feuilles de S. mombin obtenue in vitro est confirmée in vivo sur les brebis. Les résultats des travaux révèlent que les traitements avec la poudre de S. mombin a permis une réduction de plus de 50 % du niveau d’excrétion des œufs chez les brebis traitées.

This chemical fight is at the origin of the development of resistance of certain pathogens. Faced with this constraint, new control methods are being considered. This study proposes to evaluate in vitro and in vivo, the anthelmintic properties of Spondias mombin on Haemonchus contortus of Djallonke sheep. Biological tests of the ethanolic and methanolic extracts of the plant were carried out on the L3 larvae and on the adult worms of H contortus. For in vivo tests, three lots of parasitized ewes consist of: Control without treatment; Lot 1 and Lot 2 receiving respectively 1.45g and 2.9 g / kg / animal leaf powder of S. mombin for three days. In vitro tests showed significant (p < 0.01) values of the ability of S. mombin extracts to inhibit the migration of L3 larvae (45 - 80 %) and to reduce the motility of adult worms after 30 hours. exposure (77 to 100 %), compared to the negative reference control (PBS). It should be noted that, in general, the anthelmintic activity of S. mombin extracts is not influenced by the type of solvent used. The anti-parasitic activity of S. mombin leaves obtained in vitro is confirmed in vivo in ewes. The results of the work show that treatments with S. mombin powder resulted in a reduction of more than 50 % in the level of egg excretion in treated ewes.
