Antibacterial properties and reduction of MRSA biofilm with a dressing combining polyabsorbent fibres and a silver matrix
2016
Objective: This study was designed to evaluate the antibacterial activity of a wound dressing which combines polyacrylate fibres and a silver lipido-colloid matrix (UrgoClean Ag, silver polyabsorbent dressing), against biofilm of methicillin-resistant Staphylococcus aureus (MRSA). Method: Samples of silver polyabsorbent dressing and the neutral form of this dressing (UrgoClean) were applied to biofilms of MRSA formed on a collagen I-coated surface, cultured for 24 hours. Different exposure times were tested (1, 2, 4 and 7 days) without dressing change. The biofilm reduction was quantified by using culture methods and by confocal laser scanning microscopy experiments. Results: The applicatio…
Electrospinning of Bioactive Wound-Healing Nets
2017
The availability of appropriate dressings for treatment of wounds, in particular chronic wounds, is a task that still awaits better solutions than provided by currently applied materials. The method of electrospinning enables the fabrication of novel materials for wound dressings due to the high surface area and porosity of the electrospun meshes and the possibility to include bioactive ingredients. Recent results show that the incorporation of biologically active inorganic polyphosphate microparticles and microspheres and synergistically acting retinoids into electrospun polymer fibers yields biocompatible and antibacterial mats for potential dressings with improved wound-healing propertie…
3D-Printed Products for Topical Skin Applications: From Personalized Dressings to Drug Delivery.
2021
3D printing has been widely used for the personalization of therapies and on-demand production of complex pharmaceutical forms. Recently, 3D printing has been explored as a tool for the development of topical dosage forms and wound dressings. Thus, this review aims to present advances related to the use of 3D printing for the development of pharmaceutical and biomedical products for topical skin applications, covering plain dressing and products for the delivery of active ingredients to the skin. Based on the data acquired, the important growth in the number of publications over the last years confirms its interest. The semisolid extrusion technique has been the most reported one, probably …
Derecho de acceso a la información : el desafío de una sociedad guiada por la transparencia en el ordenamiento jurídico español
2021
This study will address the two aspects of rights linked to information, the right to information and the right to information, to end with the formulation of some conclusions that, distancing themselves from a mere summary, seek to encourage doctrinal and political debate on assumptions that, being peacefully settled, should be reformulated in light of the repeated crisis of transparency. For this, it will be articulated by addressing, first, the most significant aspects of the right to information and its link with the right to freedom of expression, as well as the new challenges that these rights face in the digital age, to then analyze the right to information, its regulation in the Spa…
Successful closure of the root apex in non-vital permanent incisors with wide open apices using single calcium hydroxide (caoh) dressing: report of 2…
2010
Endodontic management of immature non vital permanent teeth in young pediatric patients is a great challenge to dentists. The walls of the root canals are frequently divergent and open apexes make debridement and obturation difficult. Thus closure of root apex is very essential for success of the endodontic treatment. Although different materials are used for the apexification procedure, calcium hydroxide is the material of choice for apical barrier formation and healing. There are different opinions regarding frequency of CaOH dressing change to induce complete closure of the apex. Literature suggests that dressing should be changed frequently. Therefore the aim of the present article is t…
Changes of Photosynthesis-Related Parameters and Productivity of Spring Oilseed Rape under Different Nitrogen and Sulphur Fertilizers Supply
2015
Fertilization with essential mineral elements is important to get high quality yield results. The lack of necessary mineral elements in soil can affect oilseed rape plant physiological functions, photosynthesis and plant productivity. Oilseed rape plants have high requirements for nitrogen and as oil crop – for sulphur. The aim of the investigation was to explain changes of chlorophyll a fluorescence parameters in spring oilseed rape leaves and yield changes under nitrogen and sulphur supply. During laboratory experiments changes of chlorophyll a fluorescence parameters and during field experiments changes of yield parameters under different nitrogen and sulphur supply were observed. Labora…
Comparison of implementations of the lattice-Boltzmann method
2008
AbstractSimplicity of coding is usually an appealing feature of the lattice-Boltzmann method (LBM). Conventional implementations of LBM are often based on the two-lattice or the two-step algorithm, which however suffer from high memory consumption and poor computational performance, respectively. The aim of this work was to identify implementations of LBM that would achieve high computational performance with low memory consumption. Effects of memory addressing schemes were investigated in particular. Data layouts for velocity distribution values were also considered, and they were found to be related to computational performance. A novel bundle data layout was therefore introduced. Address…
Self-dressing in classical and quantum electrodynamics
2003
A short review is presented of the theory of dressed states in nonrelativistic QED, encompassing fully and partially dressed states in atomic physics. This leads to the concept of the reconstruction of the cloud of virtual photons and of self-dressing. Finally some recent results on the classical counterpart of self-dressing are discussed and a comparison is made with the QED case. Attention is drawn to open problems and future lines of research are briefly outlined.
Travestirsi per Dioniso
2020
Starting from the definition of “performativity” and “gender parody” developed by Judith Butler, this paper aims to investigate the performative functions of male cross-dressing within the dynamics of social categorization in classical Athens. For this purpose I have adopted an eclectic hermeneutic toolbox, borrowing elements from Harvey Sacks’ Membership Categorization Analysis to René Girard’s scapegoat theory. Through the philological analysis of some literary representations of transvestism, such as Pentheus’ cross-dressing in Euripides’ "Bacchae", and the anthropological interpretation of the mythical-ritual complex relating to the effeminacy of Dionysus, my work focuses on the polyval…
Over the Cuckoo’s Nest : Towards a Nordic Model of the Responsible University?
2019
AbstractThis concluding chapter takes stock of the major elements, both empirical and conceptual, that underpin the case chapters presented in the book. The chapter is organised in three distinct sections. First, addressing a largely scientific audience, the chapter attempts to make conceptual sense of the findings from an organisational theory perspective. Second, it shifts focus to the wider community of practitioners (policy makers, advisers, university managers and administrators, etc.) by shedding light on the practical implications of the volume’s core findings for both policy and practice. Third, the chapter once again addresses an academic audience by sketching out the road ahead re…
