Intrakraniālo aneirismu endovaskulāra ārstēšana ar plūsmas novirzītāju stentiem
2016
Darba mērķis ir zinātniski pamatot intrakraniālu aneirismu endovaskulāru ārstēšanu ar plūsmas novadītājiem. Darba uzdevumi 1. apkopot esošos teorētiskos datu rezultātus par intrakraniālu aneirismu patoloģiju, anamnēzi un ārstēšanu, kur lietoti plūsmas novirzītāji; 2. apkopot PSKUS plūsmas novirzītāju lietošanas pieredzi intrakraniālu aneirismu ārstēšanā. 3. atrast saistību starp intrakraniālo stentu implantāciju un mātes asinsvada remodelāciju, aneirismas maisa mazināšanos. Metodes tika veikts retrospektīvs pētījums, kuram ētikas komisijas atļauju deva LU Eksperimentālās un klīniskās medicīnas institūta Zinātniskās izpētes ētikas komisija. Pētījumā tika analizēts 31 intrakraniālo aneirismu …
Silk fibroin scaffolds enhance cell commitment of adult rat cardiac progenitor cells.
2015
The use of three-dimensional (3D) cultures may induce cardiac progenitor cells to synthesize their own extracellular matrix (ECM) and sarcomeric proteins to initiate cardiac differentiation. 3D cultures grown on synthetic scaffolds may favour the implantation and survival of stem cells for cell therapy when pharmacological therapies are not efficient in curing cardiovascular diseases and when organ transplantation remains the only treatment able to rescue the patient’s life. Silk fibroin-based scaffolds may be used to increase cell affinity to biomaterials and may be chemically modified to improve cell adhesion. In the present study, porous, partially orientated and electrospun nanometric n…
Palabras tejidas: método y uso de un tesauro multilingüe de la seda
2021
El patrimonio europeo de la seda es un patrimonio integral que abarca tanto bienes materiales (telares, tejidos, hilos, etc.) como un importante patrimonio inmaterial lingüístico. Su importancia como patrimonio es indudable, pero aunque la seda ha tejido Europa y se sigue utilizando en numerosos contextos, la tejeduría tradicional está en riesgo por la pérdida gradual de artesanos que salvaguarden el conocimiento ancestral. Además, la seda sigue siendo relevante para las personas que experimentan conexiones vivas, personales y sociales con este patrimonio, el cual está vinculado a tantas historias de vida y relatos colectivos que ha generado numerosos vocablos propios. El modo en que se han…
El hilo de la historia: del patrimonio mueble al intangible. Rescatando el patrimonio textil sedero
2021
[EN] Silk heritage belongs to the so-called integral heritage type, which means that tangible and intangible elements can be found in one piece. Moreover, silk is a living heritage strongly connected with its community. It is paradigmatic case, where its intangible elements go from literature, to mulberry farming, or traditional weaving techniques. Also, activities surrounding silk trade have left an imprint on various cities in monuments and even marking their town planning. Nowadays, silk is a living heritage in various communities and constitutes an element of creativity that can be appreciated in the current fashion trends. This paper addresses the main results of the SILKNOW project, f…
Silk Road Museums: Design of Inclusive Heritage and Cross-Cultural Education
2021
This work is the result of a study on the characteristics that define some of the museums created on the Silk Road. The approach to these museums has focused especially on the observation of the educational and heritage aspects that define these institutions. Since 1988, numerous actions related to the Silk Road have been promoted by UNESCO. This old trade route has now become a route of dialogue between cultures. Each museum studied is characterized by promoting local and national issues that define it. Educational issues stand out, since the tradition of silk production is very important in each place. Another aspect observed is that heritage issues manage to strengthen the characteristic…
Biomimetic composites with enhanced toughening using silk-inspired triblock proteins and aligned nanocellulose reinforcements
2019
Silk-like proteins produced in bacteria are used as adhesives for cellulose nanofibrils to make a new biological material.
Cooperation Formats of China and Europe: Synergies and Divergences
2017
Abstract This contribution articulates the synergies and divergences of the various formats of cooperation between China and the European countries. The EU and China have a strong interest in each other’s flagship initiatives, namely the Investment Plan for Europe, and the One Belt, One Road Initiative (Silk Road Economic Belt and 21st-Century Maritime Silk Road). The authors argue that there are certain synergies between these initiatives. Furthermore, the new initiative EU-China Connectivity Platform is aimed to explore these synergies. The authors explore the recent developments in the EU-China investments, trade cooperation and the challenges of the ever-growing CEEC-China partnership i…
Glycopolymer Functionalization of Engineered Spider Silk Protein-based Materials for Improved Cell Adhesion
2014
Silk protein-based materials are promising biomaterials for application as tissue scaffolds, due to their processability, biocompatibility, and biodegradability. The preparation of films composed of an engineered spider silk protein (eADF4(C16)) and their functionalization with glycopolymers are described. The glycopolymers bind proteins found in the extracellular matrix, providing a biomimetic coating on the films that improves cell adhesion to the surfaces of engineered spider silk films. Such silk-based materials have potential as coatings for degradable implantable devices.
Methionine in a protein hydrophobic core drives tight interactions required for assembly of spider silk
2019
Web spiders connect silk proteins, so-called spidroins, into fibers of extraordinary toughness. The spidroin N-terminal domain (NTD) plays a pivotal role in this process: it polymerizes spidroins through a complex mechanism of dimerization. Here we analyze sequences of spidroin NTDs and find an unusually high content of the amino acid methionine. We simultaneously mutate all methionines present in the hydrophobic core of a spidroin NTD from a nursery web spider’s dragline silk to leucine. The mutated NTD is strongly stabilized and folds at the theoretical speed limit. The structure of the mutant is preserved, yet its ability to dimerize is substantially impaired. We find that side chains of…
Di seta et oro. Antichi tessuti nelle chiese di Acireale
2021
This book dedicated to the ancient silk and gold fabrics of the church of Acireale in Sicily, is a text prepared by Fabio Francesco Grippaldi and Maurizio Vitella within the European project H2020 Silknow: Weaving our past into the future (European Union's Horizon 2020 research and innovation program under grant agreement No 769504). It presents a large collection of textile artefacts, largely unpublished, in use in the basilicas of Acireale. The sacred vestments analyzed both in the introductory essays and in the analytical sheets are contextualized in the broad panorama of reference, both national and European, and cover a chronological span that extends from the sixteenth to the twentiet…
