Feedback and Communication in Active Hydrogel Spheres with pH Fronts: Facile Approaches to Grow Soft Hydrogel Structures

2021

Abstract Compartmentalized reaction networks regulating signal processing, communication and pattern formation are central to living systems. Towards achieving life‐like materials, we compartmentalized urea‐urease and more complex urea‐urease/ester‐esterase pH‐feedback reaction networks into hydrogel spheres and investigate how fuel‐driven pH fronts can be sent out from these spheres and regulated by internal reaction networks. Membrane characteristics are installed by covering urease spheres with responsive hydrogel shells. We then encapsulate the two networks (urea‐urease and ester‐esterase) separately into different hydrogel spheres to devise communication, pattern formation and attracti…

PHOTOCROSSLINKING OF DEXTRAN AND POLYASPARTAMIDE DERIVATIVES: A COMBINATION SUITABLE FOR COLON- SPECIFIC DRUG DELIVERY.

2007

The aim of this study was to prepare and characterize novel hydrogels with polysaccharide–polyaminoacid structure, able to undergo an enzymatic hydrolysis in the colon and potentially useful for treating inflammatory bowel diseases (IBD). Starting materials were methacrylated dextran (DEX-MA) and methacrylated α,β-poly(N-2-hydroxyethyl)-DL-aspartamide (PHM). These polymers were photocrosslinked by exposure of their aqueous solutions at 313 nm without photoinitiators. Different samples, shaped as microparticles, were obtained as a function of polymer concentration and irradiation time. FT-IR analysis confirmed the occurrence of a co-crosslinking between DEX-MA and PHM in all experimental con…

2023

Los hábitos alimentarios de los consumidores han cambiado progresivamente en las últimas décadas, buscando una alternativa de alimentos con alto valor nutricional e impacto en la salud. En ese sentido, los productos panarios son clave en la dieta y poseen potencial para ser adicionados con ingredientes nutritivos y saludables. Sin embargo, esto presenta un desafío tecnológico debido a la inclusión de ingredientes carentes de gluten, además de cumplir con las expectativas de los consumidores en cuanto a características de producto fresco con el mismo valor nutricional/funcional a pesar de no ser elaborado en el día. Para ello, la tecnología de elaboración de productos panarios precocidos y c…

Measuring Internet Gaming Disorder and Gaming Disorder : A Qualitative Content Validity Analysis of Validated Scales

2021

Numerous instruments have been developed to measure gaming-related health problems based on “internet gaming disorder” (IGD) in the third section of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) and “gaming disorder” (GD) in the International Classification of Diseases (11th rev.). However, the criteria in the manuals tend to be operationalized in numerous diverse ways, which can make screening outcomes incomparable. A content validity analysis is needed to reassess the relationships between the diagnostic criteria and the items that operationalize them. The IGD and GD criteria were divided into sematic components. A qualitative content validity analysis was carried ou…

Coping to play : the effect of user-driven innovations on user experience in games

2017

Tässä Pro Gradu -tutkielmassa tutkitaan miten käyttäjälähtöisiä innovaatioita voi hyödyntää videopeleissä esiintyvien käytettävyysongelmien selvittämisessä coping-keinona. Lisäksi käsitellään käyttäjälähtöisten innovaatioiden vaikutusta pelien käyttökokemukseen. Aihe on tärkeä erityisesti peliteollisuudelle, sillä useat peliyhtiöt ovat antaneet pelaajille mahdollisuuden muokata pelejä tietyiltä osin luomalla modifikaatioita, (engl. modification, mod) joilla voidaan vaikuttaa pelin ulkoasuun, mekaniikkaan ja sisältöön. Pelikehityksen jatkaminen lisäsisällön luomisella peliyhteisössä on nykyään merkittävä osa pelikulttuuria, joten peliyritysten on tärkeää ymmärtää sen sisältämät mahdollisuude…

Why do adults seek treatment for gaming (disorder)? A qualitative study

2022

Despite gaming disorder now being diagnosable by the International Classification of Diseases (ICD-11) as a new mental disorder due to addictive behaviors, little is known about the concrete reasons for which people seek treatment for their videogame play. As the current literature is mainly based on children and adolescents, there is a strong need for better understanding adult treatment-seekers in particular. This preregistered study responds to the gap in research by qualitatively investigating the reasons for treatment-seeking with 110 participants who had sought help for their videogame play from a Finnish treatment program. We applied template analysis to the open-ended data, which co…
