Study on the Influence of Beginner Gymnasts’ Neuromuscular Control Using Computer-assisted Move 1 Du Portable Appliance
2014
Abstract The study aims at evaluating, training and improving upper limb neuromuscular control in preschool gymnasts as well as at highlighting the benefits of using computerized resources (MOVE 1 DU portable appliance) in training this control type. The research method chosen for this project consists in conducting an experiment on a group of 10 subjects aged 6-7 years. The key purpose of this study is to offer a more accurate and realistic view on the potential use of computer resources in training the neuromuscular control of the upper limb.
Depression mediates physical activity readiness and physical activity in patients with heart failure.
2021
Aims Although physical activity (PA) and exercise are essential for patients with heart failure (HF), adherence to the recommended guidelines is low. Not much is known about the mediating effect of HF patients mental state with their readiness for PA and reported activity levels. The purpose of this study is to investigate the mediatory effect of depression on PA readiness (physical limitation and psychological readiness) and self-reported PA in patients with HF. Methods and results In this cross-sectional study, 163 New York Heart Association Class I and II HF patients, during their clinic visit, reported on their physical limitation (PAR-Q) and psychological readiness [self-efficacy (ESES…
Comparison between logbook-reported and objectively-assessed physical activity and sedentary time in breast cancer patients: an agreement study
2017
BACKGROUND: Increasing physical activity (PA) and decreasing sedentary time (ST) have important health effects among breast cancer patients, a growing population group. PA and sedentary behaviors are complex multi-dimensional behaviors and are challenging to monitor accurately. To date few studies have compared self-reports and objective measurement in assessing PA and ST in women undergoing breast cancer treatments. The aim of the present study was to compare self-reports and objective measures for assessing daily time spent in moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA) and ST in women undergoing breast cancer treatments. METHODS: Baseline data f…
Effects of combined electromyostimulation and gymnastics training in prepubertal girls.
2011
This study investigated the effects of a 6-week combined electromyostimulation (EMS) and gymnastic training program on muscle strength and vertical jump performance of prepubertal gymnasts. Sixteen young women gymnasts (age 12.4 ± 1.2 yrs) participated in this study, with 8 in the EMS group and the remaining 8 as controls. EMS was conducted on knee extensor muscles for 20 minutes 3 times a week during the first 3 weeks and once a week during the last 3 weeks. Gymnasts from both groups underwent similar gymnastics training 5-6 times a week. Isokinetic torque of the knee extensors was determined at different eccentric and concentric angular velocities ranging from -60 to +240° per second. Jum…
On the Ultrastructure and Function of Rhogocytes from the Pond Snail Lymnaea stagnalis
2015
Rhogocytes, also termed “pore cells”, occur as solitary or clustered cells in the connective tissue of gastropod molluscs. Rhogocytes possess an enveloping lamina of extracellular matrix and enigmatic extracellular lacunae bridged by cytoplasmic bars that form 20 nm diaphragmatic slits likely to act as a molecular sieve. Recent papers highlight the embryogenesis and ultrastructure of these cells, and their role in heavy metal detoxification. Rhogocytes are the site of hemocyanin or hemoglobin biosynthesis in gastropods. Based on electron microscopy, we recently proposed a possible pathway of hemoglobin exocytosis through the slit apparatus, and provided molecular evidence of a common phylog…
Bacteriophage Adherence to Mucus Mediates Preventive Protection against Pathogenic Bacteria
2019
The mucosal surfaces of animals are habitat for microbes, including viruses. Bacteriophages—viruses that infect bacteria—were shown to be able to bind to mucus. This may result in a symbiotic relationship in which phages find bacterial hosts to infect, protecting the mucus-producing animal from bacterial infections in the process. Here, we studied phage binding on mucus and the effect of mucin on phage-bacterium interactions. The significance of our research is in showing that phage adhesion to mucus results in preventive protection against bacterial infections, which will serve as basis for the development of prophylactic phage therapy approaches. Besides, we also reveal that exposure to m…

Research data of an article: "Application of high resolution melting assay (HMR) to study temperature dependent infraspecific competition in an patho…
2017
Studies on species’ responses to climate change have focused largely on the direct effect of abiotic factors and in particular temperature, neglecting the effects of biotic interactions in determining the outcome of climate change projections. Many microbes rely on strong interference competition; hence the fitness of many pathogenic bacteria could be a function of both their growth properties and intraspecific competition. However, due to technical challenges in distinguishing and tracking individual strains, experimental evidence on intraspecific competition has been limited so far. Here, we developed a robust application of the high-resolution melting (HRM) assay to study head-to-head co…
Estrategias para mejorar la calidad de las separaciones en cromatografía líquida de fase inversa
2015
La Memoria de Tesis Doctoral propone estrategias dirigidas a mejorar la separación de mezclas que muestran una resolución cromatográfica extraordinariamente baja, en las condiciones usuales de elución, mediante cromatografía líquida de alta eficacia (HPLC, high-performance liquid chromatography). La HPLC es actualmente la técnica analítica de separación más extendida, debido a su amplio campo de aplicación, fiabilidad, robustez y sensibilidad. Lamentablemente, la eficacia que proporciona suele ser inferior a la conseguida en cromatografía de gases, electroforesis capilar y otras técnicas de electromigración, lo que representa una limitación para el análisis de muestras complejas. Los estudi…
Skriftliga och muntliga färdigheter i undervisning av svenska som modersmål vid gymnasiet i Finland : en fallstudie
2016
Tämän tutkielman tarkoitus oli tutkia ruotsi äidinkielenä opetusta lukion pakollisilla kursseilla Suomessa kirjallisten ja suullisten taitojen näkökulmista. Tarkoituksenani oli selvittää, mitä opettajat painottavat opetuksessa, millaisia tehtäviä, työskentelymenetelmiä ja työskentelytapoja he käyttävät. Tutkimusaineisto kerättiin kyselylomakkeella, joka lähetettiin kahdelle opettajalle ruotsinkieliseen lukioon Suomessa. Materiaali analysoitiin kvalitatiivisena tapaustutkimuksena. Kyselyyn vastanneet opettajat pitivät tärkeimpänä kielen mukauttamista tekstityyppiin. He painottivat taitoa osata kirjoittaa erilaisia tekstejä. Opettajat käyttävät kirjallisten taitojen opetuksessa referaatteja, …
