Lipid peroxidation capacities in the myocardium of endurance-trained rats and mice in vitro.
1992
The endurance-training programme in Experiment 1 (Exp. 1) consisted of a total swimming time of 149–159 h per male Han Wistar rat and in Experiment 2 (Exp. 2) the male NMRI-mice run on a treadmill at a speed of 25 m min-1 1 h per day, 5 days a week for 3 weeks. One group of the rat hearts was perfused with 0.3 mm cumene hydroperoxide (CumOOH) while the others were fractioned (mitochondria, sarcolemma and sarcoplasmic reticulum) and these cell fractions and homogenates were used to determine the total concentration of peroxidative lipids and the susceptibility to lipid peroxidation. The perfusion with CumOOH caused the release of thiobarbituric acid reactive substances (TBARS) into the perfu…
Molecular adaptations of voltage-gated sodium ion channel related proteins after fatiguing stretch-shortening cycle exercise
2008
Dystrophin associated protein alpha-syntrophin is known to interact with voltage-gated sodium ion channel (NaCh). Dystrophin is known to be sensitive to eccentric muscle actions. For this reason, the function of the NaChs might also be affected. Molecular adaptations of dystrophin, alpha-syntrophin and NaChs were investigated after fatiguing stretch-shortening cycle (SSC) exercise, which consisted of unilateral jumps on a sledge apparatus. Muscle biopsies were taken from the vastus lateralis muscle of eight healthy subjects immediately after (IA) and 2 days after (2D) the exercise to analyze mRNA levels and immunohistochemical staining patterns. SSC exercise resulted in decreased isometric …
Gender differences in skeletal muscle fibre damage after eccentrically biased downhill running in rats
1999
Specific antibodies against structural proteins of muscle fibres (actin, desmin, dystrophin) and extracellular matrix (fibronectin) were used to study the effect of eccentrically biased downhill running exercise (13,5 degrees, 17 m min(-1), 130 min) on the magnitude and properties of myofibre injury in the quadriceps femoris muscle of male and female rats. Muscle beta-glucuronidase activity, a quantitative indicator of muscle damage, showed clearly smaller increase in female than in male rats during the 4-day period following exercise. A similar course of histopathological changes was observed in both sexes, although females showed slower and less marked changes than males. In males, discon…
Medical therapy or revascularization for patients with chronic total occlusion? A dilemma almost solved
2020
Chronic total occlusion (CTO) of the coronary arteries are relatively common, observed in approximatively 15-25% of patients with coronary artery disease undergoing coronary angiography. The right coronary artery represents the most common CTO vessel, which represents about half of the CTO cases.The CTO prevalence is much higher ( 90%) among patients with prior coronary artery bypass graft (CABG), while a CTO is found in only one tenth of patients referred for ST-elevation myocardial infarction (STEMI)
Vanhempien ja opettajien lapsen taitoja koskevien uskomusten yhteydet lapsen oppijaminäkuvan kehitykseen : väitöskirja
2017
Koulunkäynti on merkittävä osa lasten elämää. Lapset viettävät koulussa suuren osan arkipäivistään, ja näin ollen monet heidän kokemuksistaan liittyvät koulumaailmaan. Sen lisäksi, että koulussa opitaan uusia taitoja, siellä muodostetaan erilaisia vuorovaikutussuhteita, saadaan palautetta omasta toiminnasta ja koetaan paljon onnistumisia ja epäonnistumisia. Koulun aloittamista onkin kuvattu kriittiseksi vaiheeksi lapsen elämässä. Lapsi kohtaa aivan uudenlaisia sosiaalisia tilanteita ja uusia haasteita erilaisissa oppimistilanteissa. Lasta arvioidaan myös eri tavalla kuin ennen. Hän saa säännöllisesti palautetta vanhempiensa ja lähipiirinsä lisäksi nyt myös opettajilta ja koulutovereilta. Tä…

Parents’ and children’s beliefs about learning Lithuanian language and their relationships to Lithuanian language achievement in Grade 2
2023
Straipsnyje nagrinėjamos 2-os klasės mokinių ir jų tėvų įsitikinimų apie lietuvių kalbos mokymąsi sąsajos su mokinių pasiekimais. Nustatyta, kad mokinių įsitikinimai apie savo gebėjimus, susidomėjimas lietuvių kalba, tėvų lūkesčiai bei 2-os klasės pasiekimai tarpusavyje siejasi teigiamais ryšiais. Kontroliuojant vaiko lytį, tėvų išsilavinimą bei 1-os klasės pasiekimus, geresnius pasiekimus 2-oje klasėje prognozuoja aukštesni tėvų lūkesčiai ir geresni vaikų savų gebėjimų vertinimai. Esminiai žodžiai: įsitikinimai apie gebėjimus, užduoties vertė, tėvų lūkesčiai, lietuvių kalbos pasiekimai. Previous studies have shown that as early as elementary school, children’s language skills are determine…
The Role of Parental Beliefs and Practices in Children's Motivation In The Changing World
2019
The role of parental involvement in their child’s education and academic success has been widely acknowledged in recent educational theories, policies, and practices. Parental beliefs and expectations concerning their child’s learning and success have been shown to be reflected in the parents’ involvement in their child’s education and their practices with their offspring, thereby shaping the child’s motivational development in school. In addition, parental trust in their child’s teacher is a key factor in enhancing the home–school partnership and in supporting a child’s academic motivation and successful schooling. However, political, economical, and technological changes in society and un…

Parental homework-help profiles throughout grades 6 – 9 : Relations to motivation and mathematics skills
2022
This study aimed to examine how parental profiles during homework help (supportive versus controlling) for children in Grades 6 and 9 change over time and relate to children’s motivation and math skills. Participants included 719 mother–child dyads. Children’s perceptions of parental help and math skills were assessed in both grades; children’s math-related self-concept, interest, and mother-rated task persistence were assessed only in Grade 6. Three similar profiles of parental help appeared in both grades. Most mothers and children belonged to the Average support and control profile (around 60% in both grades); 29–33% belonged to the Average support, high control profile; and 8–11% belong…
