Amino acid sequence and homology modeling of obtustatin, a novel non-RGD-containing short disintegrin isolated from the venom of Vipera lebetina obtu…
2003
Disintegrins represent a group of cysteine-rich peptides occurring in Crotalidae and Viperidae snake venoms, and are potent antagonists of several integrin receptors. A novel disintegrin, obtustatin, was isolated from the venom of the Vipera lebetina obtusa viper, and represents the first potent and selective inhibitor of the binding of integrin alpha(1)beta(1) to collagen IV. The primary structure of obtustatin contains 41 amino acids and is the shortest disintegrin described to date. Obtustatin shares the pattern of cysteines of other short disintegrins. However, in contrast to known short disintegrins, the integrin-binding loop of obtustatin is two residues shorter and does not express t…
Is It Possible to Educate, Intervene or “Cure” Autism Spectrum Disorder? A Content Analysis of YouTube Videos
2021
YouTube es uno de los sitios web más conocidos y de mayor acceso en todo el mundo, por lo que tiene un gran potencial pedagógico. No obstante, la calidad y la veracidad de algunos videos de YouTube son cuestionables. Las dudas sobre la confiabilidad del contenido fáctico es un factor controvertido que debe tenerse en cuenta, especialmente cuando se abordan cuestiones de salud pública. Por ello, el principal objetivo de este trabajo es analizar el contenido de los vídeos en español más vistos en YouTube relacionados con el trastorno del espectro autista (TEA). Para la realización de esta investigación se utilizaron los términos "autismo Y educación", "autismo Y intervención" y "autismo Y cur…
Artificial intelligence in the diagnosis of pediatric allergic diseases.
2020
Abstract: Artificial intelligence (AI) is a field of data science pertaining to advanced computing machines capable of learning from data and interacting with the human world. Early diagnosis and diagnostics, self-care, prevention and wellness, clinical decision support, care delivery, and chronic care management have been identified within the healthcare areas that could benefit from introducing AI. In pediatric allergy research, the recent developments in AI approach provided new perspectives for characterizing the heterogeneity of allergic diseases among patients. Moreover, the increasing use of electronic health records and personal healthcare records highlighted the relevance of AI in …
Using recorded audio feedback in multi-cultural higher e-education : How do academics experience? A thematic network analysis
2020
The aim of our study is to shed light on how academics experience using recorded audio feedback (RAF) as a feedback method in multi-cultural higher e-Education context. We adopted a qualitative content analysis approach, applying thematic network analysis to the data received from three academics (a case study). This approach proposes graphical networks as an aid for analyzing and synthesizing qualitative data into basic, organizing and global themes. The thematic network analysis produced two global, six organizing and 48 basic themes. The two global themes were named “Speaking style” and “Culture neutrality/sensitivity”. Based on our analysis, academics can, by using RAF in multi-cultural…
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
Removing ocular artifacts from magnetoencephalographic data on naturalistic reading of continuous texts
2022
Naturalistic reading paradigms and stimuli consisting of long continuous texts are essential for characterizing the cortical basis of reading. Due to the highly dynamic nature of the reading process, electrophysiological brain imaging methods with high spatial and temporal resolution, such as magnetoencephalography (MEG), are ideal for tracking them. However, as electrophysiological recordings are sensitive to electromagnetic artifacts, data recorded during naturalistic reading is confounded by ocular artifacts. In this study, we evaluate two different pipelines for removing ocular artifacts from MEG data collected during continuous, naturalistic reading, with the focus on saccades and blin…
Applying sound art research in modern electronic music production : glitch, loop, plunderphonics and sound collage as tools of production
2011
Tämä työ tehdään empiirisenä tutkimuksena äänitaiteesta ja sen suhteesta moderniin elektroniseen musiikkiin. Tätä tutkimusta varten suoritetut äänikokeilut seuraavat muutamia äänitaiteen historian pääsuuntauksia ja kertovat, miten nämä suuntaukset ovat vaikuttaneet elektronisen musiikin tuottajiin. Tutkimus on jaettu neljään osaan, joissa tutkitaan taiteen ja populäärimusiikin välistä suhdetta. Lisäksi kerrotaan, kuinka kokeellista musiikkitaidetta voidaan käyttää modernin elektronisen musiikin tuotantotyökaluna. Ensimmäinen kappale käsittää Glitch- ja Loopmusiikin väliset roolit välittömän ja välillisen nautinnon tuottajana Loop-pohjaisessa musiikissa. Samalla toinen ja kolmas kappale tutk…
Enregistrer les interactions au restaurant : atouts et contraintes d’un cadre expérimental
2013
Dans le cadre d’un travail de recherche en Analyse Conversationnelle (Sacks, 1992) traitant des dimensions linguistiques et multimodales des interactions entre le personnel de service et les clients lors d’un repas au restaurant, nous avons élaboré une partie de notre corpus dans un restaurant expérimental équipé d’un système d’enregistrement audio et vidéo. Dans cet article, nous exposerons comment ce dispositif a été utilisé pour la constitution de notre corpus afin de capter des données authentiques enregistrées dans leur contexte naturel de production.Grâce à l’analyse fine de deux extraits, nous montrerons que le dispositif technique à disposition dans cette structure ne peut pas être …
Growth and limb bone histology of aetosaurs and phytosaurs from the Late Triassic Krasiejów locality (sw Poland) reveals strong environmental influen…
2022
Abstract The growth pattern of the Polish phytosaur Parasuchus cf. arenaceus and the aetosaur Stagonolepis olenkae (both Krasiejów; Norian) was studied. Results were compared to published data of other members of these two groups and to a new sample of the German (Heslach; Norian) phytosaur Nicrosaurus sp. All three herein studied taxa display lamellar-zonal bone consisting predominately of parallel-fibred tissue and on average a low to moderate vascular density. Towards the outer cortex the thickness of annuli increases in most samples and becomes distinctly wider than the zones. Therefore, most of the appositional growth in adults was achieved during phases of prolonged slow growth. All b…
Aligned microcontact printing of biomolecules on microelectronic device surfaces
2001
Microcontact printing (/spl mu/CP) of extracellular matrix proteins is a fascinating approach to control cell positioning and outgrowth, which is essential in the development of applications ranging from cellular biosensors to tissue engineering. Microelectronic devices can be used to detect the activity from a large number of recording sites over the long term. However, signals from cells can only be recorded at small sensitive spots. Here, the authors present an innovative setup to perform aligned /spl mu/CP of extracellular matrix proteins on microelectronic devices in order to guide the growth of electrogenic cells specifically to these sensitive spots. The authors' system is based on t…
