Item The effect of Electro Magnetic Fields on Cell BehaviourTuglu, MI; Gülbagça, F; Sal, DH; Saygili, S; Sönmez, PK; Aydemir, I; Özkut, M; Öztürk, S; Gümüsay, M; Kaya, A; Keskin, NThe biologic effects of electomagnetic fields application on medical field has been increased. Their effect on medical treatment depends on cell behaviour which can be observed by in vivo and in vitro studies. Their effect on the stem cells and the cell lines and the organs of experimental animals with morphological alterations are helpful to understand cell behaviour. The behaviour of the cells can be analyse at ultrastructial level by scaning electron microscopy. Application of electomagnetic fields cause increase of proliferation, migrationand improvement of wound healing with beneficial effects while they cause oxidative stress and cell daeth including apoptosis for cancer cells in different types of cell line. The minimal side effect with maximum beneficial treatment of these products suggest that they could be very useful for clinical trials.Item Some biological properties in the Akgol (Fethiye-Mugla) population of the mosquitofish Gambusia affinis (Baird & Girard, 1853)Öztürk, S; Ikiz, RIn this study. 705 mosquitofish Gambusia affinis (Baird & Girard, 1853) were caught in Akgol Lake near the town of Fethiye in Mugla province between November 1998 and October 1999, and the biological characteristics of their growth, reproduction and feeding were studied in detail. In the mosquitofish population, the 0 aged group comprised 97.58% and the 1 + aged group 2.42%; the proportion of females was 81.40%, and that of males was 18.60%. Total length (TL) varied from 1.3 to 5.5 cm; total weight was between 0.02 and 2.31 g. The average numbers of developing eggs were 21.90 (0+) and 52.81 (1); and the average egg productivity per gram was between 27.71 (0+) and 31.71 (1). The average condition number was 1.16 +/- 0.16. The maximum condition number was 1.38, in November 1998. In the population. 34.68% of nutrition consisted of Diptera species (22.44% of this was mosquito larvae), 13.26% Nereidae family members and 11.22% Amphipoda members. Consequently, the fact that mosquito larvae are of great importance in the nourishment regime of G. affinis indicates the significance of G. affinis in the struggle against mosquitoes.Item CYANOBACTERIAL DIVERSITY AND PHYSICOCHEMICAL CHARACTERISTICS OF THERMAL SPRINGS IN THE KUTAHYA PROVINCE OF TURKEYÖztürk, SThermal springs are very difficult environments for organisms due to the high temperature, and physicochemical parameters. Cyanobacteria, which are photosynthetic prokaryotes, are best adapted to these environments. Kutahya is an important thermal area in Turkey. The aim of the study was to determine the cyanobacterial flora with a morphologic and ecologic approach in the 11 thermal. The physicochemical properties of the thermal springs in Kutahya province were measured. The thermal springs are alkaline (pH>6) with an average temperature of 52 degrees C. As a result, 54 cyanobacteria taxa were identified. Oscillatoriales were the predominant order in terms of taxa diversity (24 taxa) and biomass size. Statistical analyses were conducted to reveal the physicochemical properties of the thermal springs and the distribution of cyanobacteria in detail. According to these analyses, the thermal springs were classified into two main groups with a Piper. As a result of the RDA analysis under CANOCO 5.0, the total variation was 55.45455, and the first two axes explained a total of 57.43% of the variance. There was a significant difference (P<0.001) in the comparison of the physicochemical parameters including pH, EC, TDS, and temperature values of the thermal springs in the Kruskal Wallis tests.Item Effects of Electromagnetic Fields Application on Experimental Varicocele Model in RatsGülbagça, F; Sal, DH; Saygili, S; Sönmez, PK; Aydemir, I; Özkut, M; Öztürk, S; Gümüsay, M; Kaya, A; Tuglu, MIVaricocele is the most clinical condition which can be treated by surgery. The frequency in male is 20%. The half of infertile patient has this pathology which there is dilatation in plexus pampiniformis veins of testes. Varicocele causes increase of heat or increse of oxidative stres in seminifer tubules where they produce pathology for spermatogenesis. Low frequency magnetic fields are useful for the treatment of many area where they become important role. In this study the effect of low frequency magnetic fields on the experimental varicocele model of rat testes was investigated. The parameters for oxidative stres suggest eNOS and iNOS with apoptosis were evaluated by immunohistochemical staining. There was increaese in eNOS, iNOS and apoptosis by the varicocele experiment where there was testicular damage and low frequency magnetic fields caused decrease in oxidative stress and apoptosis. Application of magnetic fields can help the clinical varicocele pathologies either with treatment or supportive effect.Item Notes on the thermal habitat: Thirteen new records for the freshwater algal flora of TurkeyÖztürk, SThermal springs are extreme environments for organisms. Cyanobacteria are the group that adapts with success in these environments where there is little diversity of life. In this study, eight different thermal water springs were studied in Kutahya province. Thirteen cyanobacteria taxa were identified as new records for the freshwater algal flora of Turkey. Some morphological and taxonomical characteristics of the taxa were briefly described in this paper, with original photos.Item The taxonomy and distribution of algae in the thermal springs of TurkiyeÖztürk, S; Kurt, OThe algal flora and physio-chemical parameters of seven thermal springs in Denizli were studied for the first time. Samples for algal analyses were taken monthly between May 2013 and June 2014, while the physio-chemical parameters were measured seasonally. The mean pH value of the thermal springs was 6.3, and temperatures varied between 34-60 degrees C. The significant differences (P < 0.001) among the thermal springs were in their temperature and pH, as well as concentration of Cl-, Fe2+, K+, Mg2+, Na+, Li+, Ca2+, HCO3-, and SO42- . A total of 43 Cyanobacteria and three Bacillariophyta taxa were determined. The most common taxon was Spirulina subsalsa Oersted ex Gomont, sampled from five sampling sites. According to the principal component analysis (PCA), the most important determining factor for the algae was temperature, followed by concentration of K+ and Cl- ions.Item Exam Anxiety Evaluation by Heart Rate Variability in University StudentsKazdagli, H; Özel, HF; Öztürk, S; Özalp, DCT; Erdeniz, B; Özbek, M; Semin, MIItem Antiapoptotic and proliferative effect of bone marrow-derived mesenchymal stem cells on experimental Asherman modelÖztürk, S; Sönmez, PK; Özdemir, I; Topdagi, YE; Tuglu, MIPurpose: We investigated the effects of stem cell therapy as an alternative to surgical methods and medical treatments in endometrial injuries in Asherman syndrome (AS). Materials and Methods: In this study, AS model was created chemically in rats. The bone marrow-derived mesenchymal stem cells isolated from the tibia and femoral bone of male individuals of the same species (BMDSC) were given to female rats with asherman syndrome and the changes in the endometrium were evaluated by histopathological parameters. Asherman + medium, Asherman + niche, Asherman + BMDSCs, Asherman + BMDSCs + niche were formed in four groups. Results: It was observed that increased endometrial thickness, gland count and vascularization and decreased fibrous areas and apoptotic cell death with regeneration in epithelium and lamina propria in treatment groups. No histopathologic changes were observed in the right uterine horns, which were evaluated as control group.. Conclusion: BMDSCs and Niche applications can contribute to the clinic by reducing the formation of adhesion within the mechanisms causing infertility. These positive results are promising in terms of transporting Asherman studies to the clinic.It has been shown that BMDSCs and Niche may contribute to the clinic by treatment with adhesion molecules in mechanisms that cause infertility.Item Adipose-Derived Stem Cells and Application AreasKivanç, M; Öztürk, S; Gökalp, S; Özdemir, I; Tuglu, IThe use of stem cells derived from adipose tissue as an autologous and self-replenishing source for a variety of differentiated cell phenotypes, provides a great deal of promise for reconstructive surgery. The secret of the human body, stem cells are reserved. Stem cells are undifferentiated cells found in the human body placed in any body tissue characteristics that differentiate and win ever known to cross the tissue instead of more than 200 diseases and thus improve and, rejuvenates the tissues. So far, the cord blood of newborn babies are used as a source of stem cells, bone marrow, and twenty years after tooth stem cells in human adipose tissue, scientists studied more than other sources of stem cells in adipose tissue and discovered that. Increase in number of in vitro studies on adult stem cells, depending on many variables is that the stem cells directly to the desired soybean optimization can be performed.. We will conclude by assessing potential avenues for developing this incredibly promising field. The aim of this paper is to review the existing literature on applications of harvest, purification, characterization and cryopreservation of adipose-derived stem cells (ASCs).Item Reliability And Validity Study For Quick Assessment Scale Of Lymphoedem Management InformationÖzkan, Y; Okyay, P; Cerrahoglu, L; Turan, Y; Sönmez, A; Öztürk, SObjective: A scale to evaluate knowledge about lymphedema has not been found in the Turkish literature before.

Baird & Girard, 1853, originally comes from North America and has been distributed all over the world for the biological control of mosquitoes. This study aimed to determine some biological properties, such as structure, age, growth and reproduction of the populations of G. affinis in Turkey. For this purpose, between November 1998 and October 1999, 2026 mosquitofish were caught in the wetlands of Fethiye-Alkgol, Dalaman and Ortaca in Mugla province in the western Mediterranean region of Turkey and the data found were compared. In the Fethiye-Alkgol population the percentage of the 0+ age group was 97.59%, and of the 1+ age group was 2.41%: in the Dalaman population percentage of the 0+ age group was 99.71%, and of the 1+ age group was 0.29%; in the Ortaca population percentage of the 0+ age group was 94.37%, and of the 1+ age group was 5.63%. The mosquitofish population in Fethiye was 81.42% female and 18.58% male, in Dalaman 71.55% female and 28.45% male, and in Ortaca 70.42% female and 29.58% male. Total length (TL) in the Fethiye-Akgol population was 1.3-5.5 cm, in Dalaman 1.7-5.5 cm and in Ortaca 1.3-5.8 cm; and total weight (W) in Fethiye-Akgol was 0.02-2.31 g, in Dalaman 0.06-2.58 g and in Ortaca 0.02-5.83 g. In each population the gonadosomatic index (GSI) increased in March and April, had a slight decrease in May and increased again in mid May. At the beginning of January the GSI of the Fethiye population started to decrease again and the GSI decreased in Dalaman and Ortaca populations beginning in mid July. This shows that the mosquitofish is a bivoltine species. The average number of eggs belonging to each age group was 21.90 (0+) and 52.81 (1+) in Fethiye, 27.11 (0+) and 91.0 (1+) in Dalaman, and 28.24 (0+) and 81.78 (1+) in Ortaca. Average fecundity per gram was between 27.71 (0+) and 31.71 (1+) in Fethiye-Akgol, between 42.97 (0+) and 39.99 (1+) in Dalaman, and between 35.28 (0+) and 37.39 (1+) in Ortaca.Item Comparison of Mobile Interaction Management Products Using Systematic Literature Review Method and a New Product SuggestionÖztürk, S; Elmas, C; Bozyigit, F; Kilinç, DBecause of innovations and improvements in technology, the use of smartphones that make it easier for users to work has become widespread.

In order to acquire loyal mobile-app user, Machine Learning support system is proposed as solution.Item Efficacy of Lacosamide Therapy in Focal Onset Refractory Epilepsy of Childhood: A Single Center ExperienceAksoy, HU; Yilmaz, C; Ayça, S; Atasever, AK; Polat, M; Öztürk, SObjective: Treatment of childhood refractory epilepsy is a challenge for clinicians. Lacosamide is a new generation antiepileptic drug which is being used for focal onset seizures of adults and children. Efficacy and safety of the drug for adults have been demonstrated in various studies. The aim of this retrospective cross-sectional study is to evaluate the efficacy and safety of lacosamide in childhood refractory focal seizures in our clinic. Methods: We examined the medical records of 14 patients treated with lacosamide in our clinic between January 2016 and January 2020 in terms of demographic, etiological, neuroimaging findings, responses to treatment, adverse effects and drug-drug interactions. We evaluated the patients as responders to treatment whose seizure frequency decreased >=%50 after 6 months of lacosamide treatment. Results: in 12 patiens (%85.7) seizure frequency decreased >=%50 (rho<0.001) while 5 of them (%35.7) was seizure free. Despite to the long term treatment one patient did not response to lacosamide treatment, and 1 patient's treatment stopped due to aggravation of seizure after initiation of lacosamide treatment. Clinical adverse effects were observed in 3 (%21.4) patients. Cardiac adverse effects or drug-drug interactions were not observed in any patient. Conclusion: As a result of our study, we think that lacosamide is an effective and reliable treatment option for refractory focal seizures of childhood similar to the results of the studies cited in the literature. We also think that further investigations are needed to evaluate its efficacy in focal and different type of seizures of childhood.Item The functional effect of stem cells on the reproductive organsTuglu, I; Aydemir, I; Özkud, M; Firat, F; Öztürk, S; Sönmez, PK; Saygili, S; Sal, DH; Gülbagça, FItem Long-Term Omalizumab Treatment: A Multicenter, Real-Life, 5-Year TrialYorgancioglu, A; Erkekol, FÖ; Mungan, D; Erdinç, M; Gemicioglu, B; Özseker, ZF; Degirmenci, PB; Nayci, S; Çilli, A; Erdenen, F; Kirmaz, C; Ediger, D; Yalçin, AD; Büyüköztürk, S; Öztürk, S; Güleç, M; Isik, SR; Kalyoncu, AF; Göksel, Ö; Aydin, O; Havlucu, Y; Ar, IB; Erdogdu, ABackground: Omalizumab has demonstrated therapeutic benefits both in controlled clinical trials and real-life studies. However, research concerning the long-term effects and tolerability of omalizumab is needed. The main objective of this study was to evaluate the effectiveness and tolerability of treatment with omalizumab for up to 5 years. Methods: A multicenter, retrospective, chart-based study was carried out to compare documented exacerbations, hospitalizations, systemic steroid requirement, FEV1, and asthma control test (ACT) results during 1 year prior to omalizumab treatment versus at 1, 3, and 5 years of treatment. Adverse events and reasons for discontinuation were also recorded at each time point. Results: Four hundred and sixty-five patients were enrolled in the study. Outcome variables had improved after the 1st year and were sustained after the 3rd and 5th years of treatment with omalizumab. Omalizumab treatment reduced the asthma exacerbation rate by 71.3% (p < 0.001) at 1 year, 64.3% (p < 0.001) at 3 years, and 54.8% (p = 0.002) at 5 years. The hospitalization rate also decreased; by the 5th year of the treatment no patients were hospitalized. ACT results had also improved significantly: 12 (p < 0.001) at 1 year, 12 (p < 0.001) at 3 years, and 12 (p = 0.002) at 5 years. Overall, 12.7% of patients reported adverse events (most of these were mild-to-moderate) and the overall dropout rate was 9.0%. Conclusion: Omalizumab had a significant effect on asthma outcomes and this effect was maintained over 5 years. The drug was found to be generally safe and treatment compliance was good. (C) 2018 S. Karger AG, BaselItem The knowledge and considerations of the physicians regarding the inhaler devices in asthma and COPD: the INTEDA-1 studyCaliskaner, AZ; Öztürk, C; Ceylan, E; Pekcan, S; Yilmaz, Ö; Öztürk, S; Can, C; Sener, O; Turay, ÜY; Koç, N; Ersoy, RIntroduction: The present paper was aimed at indicating and discussing the possible problems related to inhaler devices by considering the knowledge and practices of the physicians regarding the inhalation therapies. Materials and Methods: The present study is a prospective, cross-sectional survey carried out by Turkish Respiratory Society Inhalation Therapy Group between February 2010 and February 2011 with a participation of ten individual centres. Seven inhaler devices that were available on the market in the country were assessed. The data on the problems that 684 clinicians actively attending patients with respiratory disorders experienced in daily clinical practice or their evaluations of their patients were obtained through the questionnaire. Results: The respondents, most of whom were pulmonologist (37.5%), and pediatrist (38.1%), had been, on average, 11.6 years in profession. The source of information on inhalers and administration techniques were reported to be mainly the internet and patient leaflets. Of the participants only 18.5% reported to have had adequate knowledge of inhaler devices and proper administration techniques. Most of the participants stated that they themselves provided the instructions of administration and that the method was often verbal explanation. The physicians believed that although approximately 60% of the patients used the drug correctly, 40.7% made critical mistakes to have adverse effects on the therapeutic outcome. The most important criteria on which the physians lay greater emphasis in choosing the inhaler devices were the physical capability, skills and age of the patients. Conclusion: The awareness of proper use of inhaler devices is a fundamental prerequisite for effective inhalation therapy has been improved in physicians. The results of the present study have shown that more effort is required for professional training. Assisting the physicans with medical personnel for training of the patients and educational motivation are required.Item Levothyroxine poisoning in children is usually benign: A multi-center experience from TurkeySen Küçük, K; Demir, S; Sevim, RD; Akgül, F; Yalçin, G; Eser, Ö; Bal, A; Ergün, E; Öztürk, S; Anik, AItem In vitro hypoxia effect on cancer stem cellsGörgün, C; Öztürk, S; Gökalp, S; Vatansever, S; Gürhan, ID; Ürkmez, ASItem Gastrostomy in Hospitalized Patients with Acute Stroke: NoroTek Turkey Point Prevalence Study Subgroup AnalysisTopçuoglu, MA; Özdemir, AÖ; Aykaç, Ö; Milanoglu, A; Gökçe, M; Bavli, S; Çabalar, M; Yayla, V; Erdogan, HA; Özkul, A; Günes, A; Degirmenci, B; Aluçlu, U; Kozak, HH; Güngör, L; Erdogan, M; Acar, ZÖ; Cenikli, U; Kablan, Y; Yilmaz, A; Genç, H; Nazliel, B; Çaglayan, HB; Gencer, ES; Ay, H; Demirbas, H; Akdogan, Ö; Emre, U; Yildiz, ÖK; Bolayir, A; Demir, T; Tanriverdi, Z; Tekan, ÜY; Akpinar, ÇK; Özkan, E; Ilik, F; Sirin, H; Güler, A; Önder, H; Bektas, H; Öcek, L; Bakar, M; Ongun, N; Krespi, Y; Isikay, CT; Aslanbaba, E; Sorgun, M; Gürkas, E; Karadeli, HH; Midi, I; Ilgezdi, I; Bilgiç, AB; Akyol, S; Epçeliden, MT; Atmaca, MM; Kursun, O; Keskin, O; Sirinocak, PB; Baydemir, R; Akçakoyunlu, M; Öztürk, S; Özel, T; Ünal, A; Dora, B; Yürekli, VA; Arlier, Z; Eren, A; Yilmaz, A; Kisabay, A; Acar, B; Bastan, B; Acar, Z; Niflioglu, B; Güven, B; Kaya, D; Afsar, N; Yazici, D; Aytaç, E; Yaka, E; Toplutas, E; Degirmenci, E; Ince, FB; Büyükserbetçi, G; Aydin, I; Çetiner, M; Sen, M; Turgut, N; Kale, N; Çoban, E; Yesilot, N; Ekizoglu, E; Kizek, Ö; Birgili, Ö; Yevgi, R; Kunt, R; Giray, S; Akkas, SY; Senadim, S; Yoldas, T; Asil, T; Duman, T; Atasoy, T; Çinar, BP; Demir, T; Can, U; Ünsal, YÖ; Eskut, N; Aslan, Y; Bas, DF; Sener, U; Yilmaz, Z; Bozdogan, Z; Alioglu, Z; Arsava, EMObjective: Nutritional status assessment, dysphagia evaluation and enteral feeding decision are important determinants of prognosis in acute neurovascular diseases. Materials and Methods: NoroTek is a point prevalence study conducted with the participation of 87 hospitals spread across all health sub regions of Turkey conducted on 10-May-2018 (World Stroke Awareness Day). A total of 972 hospitalized neurovascular patients [female: 53%, age: 69 +/- 14; acute ischemic stroke in 845; intracerebral hematoma (ICH) in 119 and post-resuscitation encephalopathy (PRE) in 8] with complete data were included in this sub-study. Results: Gastrostomy was inserted in 10.7% of the patients with ischemic stroke, 10.1% of the patients with ICH and in 50% of the patients with PRE. Independent predictors of percutaneous endoscopic gastrostomy (PEG) administration were The National Institutes of Health Stroke Scale score at admission [exp (ss): 1.09 95% confidence interval (CI): 1.05-1.14, per point] in ischemic stroke; and mechanical ventilation in ischemic [exp (ss): 6.18 (95% CI: 3.16-12.09)] and hemorrhagic strokes [exp (ss): 26.48 (95% CI: 1.36-515.8)]. PEG was found to be a significant negative indicator of favorable (modified Rankin's scale score 0-2) functional outcome [exp (ss): 0.032 (95% CI: 0.004-0.251)] but not of in-hospital mortality [exp (ss): 1.731 (95% CI: 0.785-3.829)]. Nutritional and swallowing assessments were performed in approximately two-thirds of patients. Of the nutritional assessments 69% and 76% of dysphagia assessments were completed within the first 2 days. Tube feeding was performed in 39% of the patients. In 83.5% of them, tube was inserted in the first 2 days; 28% of the patients with feeding tube had PEG later. Conclusion: The NoroTek study provided the first reliable and large-scale data on key quality metrics of nutrition practice in acute stroke in Turkey. In terms of being economical and accurate it makes sense to use the point prevalence method.Item The effect of personal, familial, and environmental characteristics on acne vulgaris: a prospective, multicenter, case controlled studyKaradag, AS; Balta, I; Saricaoglu, H; Kiliç, S; Kelekçi, KH; Yildirim, M; Arica, DA; Öztürk, S; Karaman, G; Çerman, AA; Bilgili, SG; Turan, E; Demirci, MM; Uzunçakmak, TK; Güvenç, SC; Ataseven, A; Ferahbas, A; Aksoy, B; Çölgeçen, E; Ekiz, Ö; Demir, FT; Bilgiç, Ö; Çakmak, S; Uçmak, D; Özuguz, P; Konkuralp, YK; Ermertcan, AT; Gökdemir, G; Baskan, EB; Alyamaç, G; Sanli, HBACKGROUND: There are only a few studies about epidemiological features of acne vulgaris in the literature. The aim of this study was to analyze demographic, clinical, familial and environmental characteristics of acne, the role of diet and aggravating factors and association of these factors with acne severity. METHODS: Patients with a diagnosis of mild-moderate to severe acne were consecutively interviewed at the participating centers during the study period. RESULTS: A total of 3826 patients and 759 control patients were involved in this study. Mild acne was the most common type of acne, and most of the lesions were localized on face followed by the trunk. The severity of acne was worse in patients who had a positive family history of acne. The most common triggering factor was psychological stress. We found a positive correlation with chocolate, bread, green tea, milk, white sugar, ripe banana, ice cream, apple, orange, and red meat consumption. As we compare the acne severity according to geographical features we detected mild-moderate acne was more common in Mediterranean region and severe acne was more common in East Anatolian region. Family history positivity was more common in Aegean region and least common in Central Anatolian region. There was statistically significant relationship as we compare acne severity and dietary factors such as chocolate, dairy products such as milk, sunflower seed consumption within the geographical regions. CONCLUSIONS: This study presents the demographic and clinical characteristics of acne patients in Asian and the European parts of Turkey. We believe that this study will provide a useful overview of acne in Turkey.
