Chitosomes as drug delivery systems for C-phycocyanin: preparation and characterization.
2010
The aim of this work was to investigate chitosomes, i.e. liposomes coated by a polyelectrolyte complex between chitosan (CH) and xantan gum (XG), as potential delivery system for oral administration of the protein C-phycocyanin. To this purpose several CH-XG-microcomplexes were prepared in aqueous lactic acid at different chitosan-xanthan gum percent ratios and rheological properties of the microcomplexes were studied to analyse the contribution of chitosan and xanthan gum in the reaction of microcomplexation. After establishing the best microcomplexes, chitosomes were prepared by coating C-phycocyanin loaded liposomes with the CH-XG hydrogels using spray-drying or freeze-drying. The chitos…
Design and implementation of modelling tasks using iPad's: a dual perspective
2016
[EN] This paper presents the design of two experiences to introduce modelling of physical phe-nomena through modelling tasks using iPadR's. Each of the proposals is designed with adi erent vision about modelling. In one case modelling is used as a vehicle to introduceprecise mathematical contents. While, on the other one, we intend to develop an activitythat can help student to improve their modelling competence. Our aim is to present twoproposals to introduce modelling in a ninth or tenth grade classroom

Bezūdens kalcija hidrogēnfosfāta izmantošana zopiklona tablešu ražošanā
2015
Bezūdens kalcija hidrogēnfosfāts ir plaši izmantota palīgviela, ko izmanto farmācijā, medicīnā un pārtikas ražošanā. Bezūdens kalcija hidrogēnfosfāts nodrošina zopiklona tablešu presēšanās spēju, bet tā fizikāli-tehnoloģiskās īpašības var ietekmēt tabletes mehānisko izturību un pašu tabletes ražošanas procesu. Šajā darbā tika pētīta bezūdens kalcija hidrogēnfosfāta ietekme uz izplatītu nebenzodiazepīna klases miega līdzekli zopiklonu tablešu kvalitatīvajiem rādītājiem. Bezūdens kalcija hidrogēnfosfāta kvalitatīvo rādītāju noteikšanai tika izmantotas metodes: mikroskopija, daļiņu lieluma sadalījuma noteikšana ar lāzerdifrakciju, sietu analīze, birstošu vielu tilpuma blīvuma noteikšana un vie…
Paediatric solid oral dosage forms for combination products: Improving in vitro swallowability of minitablets using binary mixtures with pellets
2023
There is a growing interest in determining and improving the acceptability of solid oral dosage forms (SODF) in paediatric populations. Combination products can be an interesting solution to combine two active pharmaceutical ingredients. This study shows that binary mixture of paediatric SODF could enhance formulation swallowability and palatability. Using the Paediatric Soft Robotic Tongue (PSRT) – an in vitro device inspired by the anatomy and physiology of 2-year-old children – we investigated the oral phase of swallowing of multi-particulate formulations, i.e., pellets (350 and 700 µm particles), minitablets (MTs, 1.8 mm), and their binary mixtures (BM), by measuring the oral swallowing…
Spray-Dried Cytisine-Loaded Matrices: Development of Transbuccal Sustained-Release Tablets as a Promising Tool in Smoking Cessation Therapy
2022
Cytisine (CYT) has emerged as a promising molecule to treat nicotine addiction, since it acts as a partial agonist of nicotinic acetylcholine receptors. However, its unfavorable pharmacokinetic properties lead to multiple administrations per day, reducing the patient’s compliance and increasing the side effects. To overcome these drawbacks, CYT buccal administration is here proposed. Firstly, CYT stability in the buccal environment was assessed and its intrinsic ability to permeate/penetrate the tissue was determined by applying CYT solutions at increasing concentrations. Furthermore, a spray-drying method was selected and optimized as it is an eco-friendly, easily scalable and effective te…
Un dispositif de prévisualisation qui améliore la navigation : comparaison entre une tablette tactile et une souris 3 D.
2015
International audience; C’est dans le cadre d’une action de recherche pluridisciplinaire (Sciences de l’Information et de la Communication, Psychologie, Ergonomie cognitive) que nous avons voulu vérifier l’hypothèse qu’un dispositif de prévisualisation pouvait améliorer les performances en recherche d’information pour des utilisateurs. L’objectif poursuivi est de tester une condition de prévisualisation en la déclinant sur une tablette tactile (expérience 1) et une souris 3 D incluant des fonctions de navigation modifiées (expérience 2). Deux modalités de recherche sont testées afin de pouvoir analyser les effets de ce dispositif. La première « normale » présente les caractéristiques classi…
Tándem : didáctica de la educación física
2018
El consumo masivo de productos y servicios digitales e internet no se corresponde con la escasa integración de las TIC en la educación y en la Educación Física. Este “cambio sin cambio”, es decir, centros con tecnología que no mejoran la enseñanza, invita a reflexionar sobre la utilidad de las TIC tradicionales y expositivas. La tecnología que mejor parece adaptarse al aprender haciendo y reflexionando sobre la acción, propia de la Educación Física, es la inalámbrica y portable, por ello el aprendizaje móvil con sus tabletas, smartphones y Apps, está llamado transformar la enseñanza de la Educación Física y deportiva.
The use of mobile technology for online shopping and entertainment among older adults in Finland
2017
Older adults use mobile devices for online shopping as often as younger adults.Mobile-based entertainment use is most typical for younger male adults.Older female adults use mobile-based entertainment least frequently.Age, household structure and high education predict mobile-based online shopping.Mobile-based entertainment use is best predicted by age and gender. Older adults are becoming an important market segment for all internet-based services, but few studies to date have considered older adults as online shoppers and users of entertainment media. Utilising the concept of life course, this article investigates the use of mobile technologies for online shopping and entertainment among …
Tablet-Supported Self-Assessment in a Class for Students with Intellectual Disability
2023
Self-assessment has been shown to have positive effects on students’ self-regulated learning strategies and academic achievement. However, self-assessment and self-assessment instruction are under-researched areas among students with intellectual disability. This data-driven qualitative study aimed at examining the self-assessment expressions students with intellectual disability documented in their learning diaries and how the teacher and teaching assistants used video recordings to facilitate students’ self-assessments in one Finnish special needs education class. The naturally occurring research data consisted of both students’ tablet-based learning diaries (N = 6) and video recordings o…
