Koululaisten fyysisen aktiivisuuden ja liikuntatunneilla koetun autonomian muutokset 7. luokalta 9. luokalle
2010
Tutkimuksen tarkoituksena oli analysoida koululaisten fyysisen aktiivisuuden ja liikuntatunneilla koetun autonomian muutoksia 7. luokalta 9. luokalle. Lisäksi tutkittiin liikuntatunneilla koetun autonomian yhteyttä fyysiseen aktiivisuuteen. Tutkimuksen osanottajiksi valittiin 639 (tytöt = 296, pojat = 343) keskisuomalaista koululaista, jotka olivat tutkimuksen alkaessa seitsemäsluokkalaisia. Tutkimukseen osallistui 8 koulua ja 32 opetusryhmää. Pitkittäisaineisto kerättiin 2007–2009 viidellä mittauskerralla, jotta alakoulusta yläkouluun siirtymisen jälkeistä kehitystrendiä voitiin seurata. Mittaukset suoritettiin strukturoiduilla kyselyillä. Oppilaiden itseraportoitua fyysistä aktiivisuutta …

Osteoprotegerin: a new biomarker for impaired bone metabolism in complex regional pain syndrome?
2014
Abstract Osteoprotegerin (OPG) is important for bone remodeling and may contribute to complex regional pain syndrome (CRPS) pathophysiology. We aimed to assess the value of OPG as a biomarker for CRPS and a possible correlation with radiotracer uptake in 3-phase bone scintigraphy (TPBS). OPG levels were analyzed in 23 CRPS patients (17 women; mean age 50 ± 9.0 years; disease duration: 12 weeks [IQR 8–24]), 10 controls (6 women; mean age 58 ± 9.6 years) and 21 patients after uncomplicated fractures (12 women; mean age: 43 ± 15 years; time after fracture: 15 weeks [IQR: 6–22]). The CRPS and control patients also underwent TPBS. OPG in CRPS patients was significantly increased by comparison wi…
Longer Nap Duration During Ramadan Observance Positively Impacts 5-m Shuttle Run Test Performance Performed in the Afternoon.
2022
It is well-documented that changes in the rhythm of life during Ramadan affect sleep schedules (i.e., interruption of night sleep patterns) and are likely to have negative effects on physical and cognitive performances. The aim of the present study was to examine the effect of different naps opportunities’ durations during Ramadan on performance of short-duration repetitive maximal exercise and perception of effort. Fifteen physically active men (age: 21 ± 3 years, height: 177 ± 6 cm, body-mass: 73 ± 10 kg) performed a 6 × 30-s shuttle run test after a 25-min nap (N25), a 45-min nap (N45), and in a no-nap condition (NN) during three experimental periods: ∼2 weeks before Ramadan (BR), the la…
Depresijas un uztvertā emocionālā siltuma bērnībā saistība ar mātes narcistiskām personības iezīmēm 18-44 gadus veciem pieaugušajiem
2022
Pētījuma mērķis bija izpētīt saistības starp depresiju, uztverto emocionālo siltumu bērnībā un mātes narcistiskām personības iezīmēm 18 – 44 gadus veciem pieaugušajiem. Pētījums tika veikts divās atkarīgās izlasēs. Pirmo izlasi veido 80 pieaugušie vecumā no 18 līdz 44 gadiem (M = 30,04, SD = 7,75), kas aizpildīja Epidemioloģijas pētījumu centra depresijas skalu (Center for Epidemiologic Studies Depression Scale (Eaton, Muntaner, Smith, Tien & Ybarra, 2004)), Latvijā aptauju adaptējušas M. Bērtule un I. Melne 2018. gadā (Bērtule & Melne, 2018), Vecāku attieksmes aptauju (Parental Bonding Instrument (Parker, Tupling & Brown, 1979)), Latvijā aptauju adaptējusi I. Bite 1998. gadā (Bite, 1998) u…
Mental fatigue induced by prolonged self-regulation does not exacerbate central fatigue during subsequent whole-body endurance exercise
2015
International audience; It has been shown that the mental fatigue induced by prolonged self-regulation increases perception of effort and reduces performance during subsequent endurance exercise. However, the physiological mechanisms underlying these negative effects of mental fatigue are unclear. The primary aim of this study was to test the hypothesis that mental fatigue exacerbates central fatigue induced by whole-body endurance exercise. Twelve subjects performed 30 min of either an incongruent Stroop task to induce a condition of mental fatigue or a congruent Stroop task (control condition) in a random and counterbalanced order. Both cognitive tasks (CTs) were followed by a whole-body …
Meaning in Life Buffers the Association between Perceived Burdensomeness, Thwarted Belongingness, and Frequency of Non-Suicidal Self-Injuries in Span…
2021
Background: Adolescence is a developmental stage when there is a high risk of engaging in non-suicidal self-injury (NSSI). There is recent interest in the study of thwarted belongingness and perceived burdensome as variables associated with the frequency of NSSI in adolescents. Meaning in life (MIL) might be negatively associated with thwarted belongingness and perceived burdensomeness. To date, no studies have analyzed the buffering role of MIL in the association between thwarted belongingness and perceived burdensomeness and the frequency of lifetime NSSI in Spanish adolescents. Aims: (a) To test whether thwarted belongingness and perceived burdensomeness are associated with frequency of …
Liver stiffness quantification in biopsy-proven nonalcoholic fatty liver disease patients using shear wave elastography in comparison with transient …
2021
Purpose: This study prospectively assessed the performance of liver stiffness measurements using point shear-wave elastography (p-SWE) in comparison with transient elastography (TE) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD). Methods: Fifty-six consecutive adult patients with a histological diagnosis of NAFLD prospectively underwent TE and p-SWE on the same day. The median of 10 measurements (SWE-10), the first five (SWE-5), and the first three (SWE-3) measurements were analyzed for p-SWE. Liver biopsy was considered as the reference standard for liver fibrosis grade. Receiver operating characteristic (ROC) curves and areas under the ROC curves (AUROCs) were cal…
Phase-delayed laser diode array allows ultrasonic guided wave mode selection and tuning
2013
Selecting and tuning modes are useful in ultrasonic guided wave non-destructive testing (NDT) since certain modes at various center frequencies are sensitive to specific types of defects. Ideally one should be able to select both the mode and the center frequency of the launched waves. We demonstrated that an affordable laser diode array can selectively launch either the S0 or A0 ultrasonic wave mode at a chosen center frequency into a polymer plate. A fiber-coupled diode array (4 elements) illuminated a 2 mm thick acrylic plate. A predetermined time delay matching the selected mode and frequency was employed between the output of the elements. The generated ultrasound was detected by a 215…
