    Effect of a 50-Hz sinusoidal electromagnetic field on the integrity of experimental colonic anastomoses covered with fibrin glue
    (2009) Girgin S.; Ozturk H.; Gedik E.; Akpolat V.; Kale E.; Ozturk H.
    Background. Low-frequency magnetic fields have been shown to affect biological In this article the effects of 50-Hz sinusoidal magnetic field (MF) stimulation and application of fibrin glue on the healing of experimental colonic anastomoses were investigated. Material and Methods. Twenty-eight rats were divided into four groups. Group 1 underwent 2-cm left colonic resection and primary anastomosis. Group 2 underwent normal resection anastomosis and the area was covered with fibrin glue. Group 3 underwent normal resection anastomosis and the rats were exposed to a 50-Hz sinusoidal MF. Group 4 underwent normal resection anastomosis, the anastomosis area was covered with fibrin glue, and the rats were exposed to a 50-Hz sinusoidal MF. Investigations included bursting pressure measurement, hydroxypro-line content, and histopathological changes. Results. Tissue hydroxyproline levels and anastomotic bursting pressures of groups 2, 3, and 4 were significantly higher than in group 1. Collagen deposition and fibroblast infiltration in groups 2, 3, and 4 had higher scores than in group 1. Furthermore, these results were significantly higher in group 4 rats than in the other groups. Histopathological examination of the anastomosis revealed significantly better healing patterns for group 4 than for groups 1, 2, and 3. Conclusions. A 50-Hz sinusoidal MF stimulation and application of fibrin glue provided a significant gain in anastomotic healing in the large intestine. A combination of a 50-Hz sinusoidal MF and fibrin glue has significantly favorable effects on healing of experimental colon anastomosis. © Copyright by Wroclaw Medical University.

    The effects of pulsed and sinusoidal electromagnetic fields on E-cadherin and type IV collagen in gingiva: A histopathological and immunohistochemical study
    (Wroclaw University of Medicine, 2013) Dogru A.G.; Tunik S.; Akpolat V.; Dogru M.; Saribas E.E.; Kaya F.A.; Nergiz Y.
    Background. The potential beneficial effects of extremely low frequency pulsed and sinusoidal electromagnetic fields have been shown on many tissues. Gingival epithelium plays an important role in immunosurveillance of the periodontal tissues. The epithelium acts as a mechanical barrier through cell junctions such as E-cadherin. Objectives. Investigation of the effects of extremely low frequency magnetic fields on gingiva. Material and Methods. Twenty-seven male Wistar albino rats were used. The rats were divided into three groups: control group (n = 9), SEMF group (n = 9), PEMF group (n = 9). The SEMF and PEMF (pulse time: 25 ?sn, pulse frequency: 50 Hz) groups were subjected to 1.5 mT, 50 Hz, exposure 6 h a day, 5 days a week for 28 days in methacrylate boxes. The gingival tissue pieces processed for routine histological and immunohistochemical examination and tissue sections were stained with H-E and Masson trichrome. In addition, E-cadherin and type IV collagen expressions were examined immunohistochemically. Results. Intraepithelial lymphocytes and proliferation of epithelial cells increased in both electromagnetic field groups. The over-expressions of E-cadherin on gingival epithelium was detected in the PEMF and SEMF groups. The expression level of type IV collagen was not significant between the control and electromagnetic field treated groups, except for a significant increase in the basal cell layer of the PEMF group, as compared to the control and SEMF groups. Conclusions. PEMF and SEMF have a local pro-inflammatory effect on gingiva, leading to an increase in E-cadherin level but not type IV collagen. Both PEMF and SEMF can be used as a supportive device in the treatment of gingival diseases, especially those which lead to defects in the epithelial barrier. © Copyright by Wroclaw Medical University.

    Investigation of the relationship between anthropometric properties and balance performance of volleyball players
    (DergiPark, 2019) Ateş N.; Ateş H.; Aktaş Y.; Akpolat V.
    Volleyball is a branch played in a relatively small area. Volleyball players have various tasks. During these tasks, keeping the balance plays an important role. Postural control during volleyball actions is very important for players. The main purpose of all sports branches is to continuously improve the physical characteristics necessary for this sport and to improve the performance of athletes. The main purpose of this study is to investigate the relationship between the anthropometric properties and balance performances of elite male volleyball players. In this study, which consists of male volleyball players playing in Turkish Men's Volleyball League (officially called The Efe League) in 2016-2017 season, the balance and anthropometric properties of twelve volunteer male volleyball players who played in MSK URFA (a team in Turkish Men's Volleyball League) in 2016-2017 season were investigated. As a result of the study, no significant relationship was found between balance and anthropometric properties. While the mean blindfolded balance of volleyball players was 1789.67 ±, the mean blindfolded squat balance was 2027,00±768,64, and the mean dynamic balance was 1178.41 ± 473.36, it was seen that there is only a low relationship between anthropometric properties of blindfolded balance and leg muscle weight/body weight percentage. There is a moderate relationship between the value of blindfolded squat balance and body mass index (BMI) and low relationship between the value of blindfolded squat balance and body fat index (BFI). It was seen that there is a moderate relationship between dynamic balance and BMI, BFI and leg muscle weight/body weight percentage © 2019 Published by International Archives of Medical Research.
