Dual Enzyme-Triggered Controlled Release on Capped Nanometric Silica Mesoporous Supports

2012

The development of nanoscopic hybrid materials equipped with “molecular gates” showing the ability of releasing target entrapped guests upon the application of an external trigger has attracted great attention and has been extensively explored during recent years.1 These nanodevices are composed of two subunits, namely, a suitable support and certain capping entities grafted on the surface of the scaffolding.2 The support is used as a suitable reservoir in which certain chemicals can be stored whereas the molecules grafted in the outer surface act as a “gate” and can control the release of the entrapped molecules at will. Both components are carefully selected and arranged in order to achie…

The Effect of Moderate- Versus High-Intensity Resistance Training on Systemic Redox State and DNA Damage in Healthy Older Women

2018

This study investigated effects of a 16-week progressive resistance training program (RTP) with elastic bands at two different intensities on systemic redox state, DNA damage, and physical function in healthy older women. Methods: Participants were randomly assigned to the high-intensity group (HIGH; n = 39), moderate-intensity group (MOD; n = 31), or control group (CG; n = 23). The exercise groups performed an RTP twice a week with three to four sets of 6 (HIGH) or 15 (MOD) repetitions of six overall body exercises at a perceived exertion rate of 8-9 on the OMNI-Resistance Exercise Scale for use with elastic bands. Thiol redox state was determined by reduced glutathione (GSH), oxidized glu…

Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…

2021

Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…

Distance Learning with Hands-on Exercises : Physical Device vs. Simulator

2022

This Research to Practice Full Paper presents a comparison between a physical device and a simulator in a distance learning context. Programming embedded devices is very commonly taught using embedded hardware. One of the most used solutions is the Arduino microcontroller platform, which allows small embedded applications to be built and commanded in a programming language. However, there are some challenges in using physical devices for educational purposes. These challenges are particularly acute in distance learning or when the course needs to be scalable to a varying number of students. To address these challenges, we explored the potential of a simulator as a replacement for a physical…

Internationalization of family-controlled SMEs from the process, network and socioemotional wealth perspectives

2016

Perheyritysten kansainvälistyminen on saanut vähän huomiota kansainvälisen liiketoiminnan tutkimusalalla. Tämä laadullinen tapaustutkimus tarttuu tähän tutkimusaukkoon ja lähestyy teemaa jopa perheyritysten kansainvälistymistutkimuksessa itsessään suhteellisen vähälle huomiolle jääneiden näkökulmien kautta: prosessi, verkosto ja sosioemotionaalinen vauraus (socioemotional wealth, SEW). Tämä tutkimus tarjoaa vastauksia siihen, kuinka perheiden kontrolloimat pk-yritykset rakentavat kansainvälisiä verkostoja, minkälaisia ulkomaiset verkostosuhteet ovat ja missä määrin SEW selittää yritysten kansainvälistymistä. Jotta tutkimustavoitteilla olisi heijastuspintaa, tutkimusta varten tehtiin kattava…

Effects of progressive aquatic resistance training on symptoms and quality of life in women with knee osteoarthritis: A secondary analysis.

2020

Abstract Objective: To conduct a secondary analysis to study the effects, those 4 months of aquatic resistance training have on self‐assessed symptoms and quality of life in post‐menopausal women with mild knee osteoarthritis (OA), after the intervention and after a 12‐month follow‐up period. Methods: A total of 87 post‐menopausal volunteer women, aged 60‐68 years, with mild knee OA were recruited in a randomized, controlled, 4‐month aquatic training trial (RCT) and randomly assigned to an intervention (n = 43) and a control (n = 44) group. The intervention group participated in 48 supervised aquatic resistance training sessions over 4 months while the control group maintained their usual l…

Exercise as stimulus for cartilage health in knee osteoarthritis

2018

Knee osteoarthritis (OA) is a leading cause of musculoskeletal pain and disability and has significant socio-economical costs globally. There is no known cure for OA. Therapeutic exercise has been shown to evoke acute positive posttreatment effects on pain and function. Even though cartilage degeneration is crucial in OA progression, there is sparse knowledge about exercise effects on osteoarthritic cartilage. The purpose of this study was to investigate the efficacy of aquatic resistance training on the estimated biochemical composition of tibiofemoral cartilage and the association between leisure time physical activity (LTPA) and tibiofemoral cartilage in postmenopausal women with mild kn…

The impact of children’s socioemotional development on parenting styles: the moderating effect of social withdrawal

2020

This study focused on associations between children’s socioemotional development (prosocial behaviour, internalizing and externalizing problems) and parenting styles (affection, behavioural control, and psychological control), and the moderating role of children’s social withdrawal (as a temperamental characteristic) in these associations. Children’s socioemotional development (n = 314) were rated by teachers at three-time points (grades 1–3). Parents completed questionnaires measuring their parenting styles at the same three-time points. The level of social withdrawal was obtained at the end of kindergarten from teachers’ reports. Panel analysis showed that prosocial behaviour was associat…

Opettajan vuorovaikutustyylien yhteys lasten koulussa käyttämiin työskentelytapoihin

2012

Tutkimuksen tarkoituksena oli selvittää yhtäältä opettajan vuorovaikutustyylien; lämpö, behavioraalinen kontrolli ja psykologinen kontrolli yhteyttä lasten koulussa käyttämiin työskentelytapoihin ja toisaalta lasten työskentelytapojen yhteyttä opettajan vuorovaikutustyyleihin. Tutkimuksessa selvitettiin myös tyttöjen ja poikien mahdollisia eroja vuorovaikutustyylien ja työskentelytapojen välisissä yhteyksissä. Tutkittavina oli 152 ekaluokkalaista (79 tyttöä, 73 poikaa) opettajineen Porin, Lappeenrannan ja Mikkelin kunnista. Tutkimus on osa laajempaa vanhemmat, opettajat ja lapsen oppiminen – tutkimushanketta (VALO). Tutkimus toteutettiin pitkittäistutkimuksena ensimmäisen kouluvuoden aikana…
