    WOS:000962094500011The aim of this study was to determine functional movement screening (FMS) scores in wrestlers to examine FMS scores in terms of years of sport experience and wrestling weight, and to determine the relationship between FMS score and body mass index (BMI). Materials and methods. Forty-four male wrestlers were included in this study. Functional movement analyses were performed of the wrestlers. In addition, the wrestlers filled out a personal information form which contains information such as age, years of sport experience, wrestling weight, and height. Results. The FMS scores of the wrestlers have been found to be 16.07 ± 1.87. A statistically significant difference has been found in terms of FMS scores according to years of sport experience and wrestling weight (p < 0.05). A statistically significant correlation has been found between the FMS score with BMI (p < 0.05). Conclusions. It has been concluded that the FMS scores of the wrestlers with more years of sport experience are higher, the FMS scores of the wrestlers with low body weight are lower, and the FMS score increases as the BMI increases. It is thought that the functional movement levels of the wrestlers should be evaluated regularly at certain intervals and interpreted according to their characteristics

    The aim of this study is to evaluate gamma ray shielding properties for bismuth doped barite-based ternary polymer composite materials. In the first stage of the study, a polymer matrix was prepared by combining orthophthalic unsaturated polyester resin (OUP), Methyl Ethyl Ketone Peroxide (MEKP) and Cobalt Octoate (6%) (Co-6). Then, barite and bismuth were added in certain proportions as filler material into this polymer matrix and thus ternary composites were produced. Experimental studies for the produced samples were carried out in narrow beam geometry using HPGe detector and 133Ba, 22Na, 137Cs, 60Co radioactive sources which emit photons between 276.4 and 1332.5 keV energy. To determine the gamma ray shielding properties of the produced ternary composites, radiation protection efficiency (RPE), linear attenuation coefficient (μ), mass attenuation coefficient (μ/ρ), half value layer (HVL), tenth value layer (TVL), mean free path (MFP), effective atomic number (Zeff), effective electron density (NE) parameters were obtained. Experimental results were compared with theoretical results obtained with WinXCOM software and GEANT4 Monte Carlo simulation code. Experimental and theoretical results were found to be compatible with each other. According to obtained results, it was found that the sample with the best shielding property among the prepared samples was BaBi50 coded sample

    WOS:001018079700001Background: Heel stick sampling, a common procedure in newborns, causes acute pain. Aims: This study aims to measure the outcome of five various non-pharmacologic pain relief groups; maternal voice, white noise, holding, maternal voice+holding, and white noise+holding. Methods: The study is an open label, randomized controlled trial. A total of 178 newborns were included in this study. Newborns were randomly allocated to each group; white noise (n = 31), maternal voice (n = 31), holding (n = 30), white noise+holding (n = 29), maternal voice+holding (n = 28), and control (n = 29) interventions. Newborns' pain responses were evaluated using the Neonatal Infant Pain Scale (NIPS), and the Premature Infant Pain Profile (PIPP). The primary measured outcomes were the newborns' pain levels, while the secondary outcomes were the heart rate and changes in oxygen saturation. The mean values of pain in neonates between groups were evaluated one minute before (Phase1), during (Phase2), and one minute after (Phase3) the procedure. Results: The research results are given with comparisons in three time periods (Phase1, Phase2 and Phase3). White noise and white noise+holding were found to have the lowest mean NIPS and PIPP score (p < 0.001). The mean heart rate was found to be the lowest in the white noise+holding group (p < 0.001). There was no significant difference between the groups in terms of oxygen saturation score (p = 0.453). Conclusion: The white noise+holding applied to newborns during heel stick sampling were effective in pain reduction. Nurses and midwives can use white noise+holding method. Implications to practice: These results contribute to the pain management of newborns

    Zinc ions (Zn2+) play a significant role in our daily lives and production, which is related to human health and environment protection. Therefore, it is crucial in this field to develop sensors with improved analyte selectivity and sensitivity. We prepared a fluorescent sensor, DIH, through the reaction of 5-(tert-butyl)-2-hydroxyisophthalaldehyde with isonicotinohydrazide. DIH, in free form, can undergo excited state intramolecular proton transfer (ESIPT) process upon excitation. Among a wide range of metal ions tested, only Zn2+ inhibited this ESIPT process, resulting in an increase in fluorescence intensity (13.3-fold) with chelation enhancement fluorescence process (CHEF). The complex (DIH/Zn2+) stoichiometry was determined to be 1:1 and the binding constant of the complex was estimated as 3.18 × 107 M−1. DIH could also be applied to detect zinc ions down to a low concentration level of 11.2 nanomolar with fluorescence spectroscopy. Moreover, the cytotoxicity evaluation of DIH against human colon adenocarcinoma cells lines demonstrated that the sensor was nontoxic and could be used successfully in cellular imagin

    Introduction and aim. Parents of children who are addicted to technology have many problems in home care. This study aimed to describe the home care experiences of mothers of children with tracheostomies. Material and methods. The study adopted Husserl’s phenomenological method, a qualitative research design. The sample consisted of 23 mothers of children with tracheostomies followed up in the pediatric pulmonology outpatient clinic of a university hospital. All participants cared for their children at home. Data were collected using a sociodemographic questionnaire and a semi-structured interview questionnaire. All interviews were recorded and transcribed. Results. Children (12 girls and 11 boys) had a mean age of 3.43±3.326 years. The mean age of tracheostomy insertion was 2.8±2.508 years. Seventeen children were on ventilator support. All participants were mothers with a mean age of 32.34±6.00 years. Half the mothers had primary school degrees (52.2%). The interviews revealed one main theme (burnout), three subthemes (social isolation, perception of competence, and regrets), and five categories (burden of care, fear, awareness, decisions, and role confusion). Conclusion. Mothers of children with tracheostomies experience numerous problems when they provide home care. They mostly have difficulty improving themselves and enduring role confusion. We must address the issues mothers of children with tracheostomies face during home care to reduce the prevalence of potential complications and improve the quality of care for both them and their children. © 2023 Sociedad espanola de dietetica
