Öğe Almond milk-based yogurt: a new perspective for athlete nutrition(Tzaneio General Hospital, 2023) Oral, Onur; Kavas, Nazan; Kavas, GokhanBackground: Nutrition is an essential aspect of an athlete's life. This study aims to investigate alternative products and propose new perspectives. In this study, almond milk, obtained from almonds whose functional property is well-known, is enriched with egg white protein powder (EWPP) and various disaccharides. Thus a non-milk-based fermented product is produced. Methods: To promote the viability of starter cultures, sucrose and maltose were first added to almond milk at a rate of 1.0% w/v. Afterward, sucrose and maltose milk were pasteurized at 85 degrees C for 20 minutes and cooled to 50-55 degrees C. Following the cooling, the EWPP (6% w/v) and the dry matter were adjusted to 12-13%. Results: In this study, physicochemical, rheological, and sensory properties of fermented products, which were obtained with EWPP and different disaccharides, were determined on the 1st, 7th, 14th, and 21st days of storage. In the study, almond milk and fatty acid compositions of non-milk-based fermented products produced from this milk were determined on the first day of storage. It was determined that fermented products made by adding maltose to almond milk were more acceptable in physicochemical, sensory, and rheological aspects than sucrose-added fermented products. Conclusion: Regarding our extensive studies, there is evidence that almond milk-based product is a sufficient alternative to cow's milk-based products. The Almond milk-based product used in this study is a nutrient that should be and athletes.Öğe Bioactive glass particulate filler composite: Effect of coupling of fillers and filler loading on some physical properties(Elsevier Sci Ltd, 2014) Oral, Onur; Lassila, Lippo V.; Kumbuloglu, Ovul; Vallittu, Pekka K.Objectives. The aim of this study was to investigate the effect of silanization of biostable and bioactive glass fillers in a polymer matrix on some of the physical properties of the composite. Methods. The water absorption, solubility, flexural strength, flexural modulus and toughness of different particulate filler composite resins were studied in vitro. Five different specimen groups were analyzed: A glass-free control, a non-silanized bioactive glass, a silanized bioactive glass, a non-silanized biostable glass and a silanized biostable glass groups. All of these five groups were further divided into sub-groups of dry and water-stored materials, both of them containing groups with 3 wt%, 6 wt%, 9 wt% or 12 wt% of glass particles (n = 8 per group). The silanization of the glass particles was carried out with 2% of gamma-3-methacryloxyproyltrimethoxysilane (MPS). For the water absorption and solubility tests, the test specimens were stored in water for 60 days, and the percentages of weight change were statistically analyzed. Flexural strength, flexural modulus and toughness values were tested with a three-point bending test and statistically analyzed. Results. Higher solubility values were observed in non-silanized glass in proportion to the percentage of glass particles. Silanization, on the other hand, decreased the solubility values of both types of glass particles and polymer. While 12 wt% non-silanized bioactive glass specimens showed -0.98 wt% solubility, 12 wt% silanized biostable glass specimens were observed to have only -0.34 wt% solubility. The three-point bending results of the dry specimens showed that flexural strength, toughness and flexural modulus decreased in proportion to the increase of glass fillers. The control group presented the highest results (106.6 MPa for flexural strength, 335.7 kPA for toughness, 3.23 GPa for flexural modulus), whereas for flexural strength and toughness, 12 wt% of non-silanized biostable glass filler groups presented the lowest (70.3 MPa for flexural strength, 111.5 kPa for toughness). For flexural modulus on the other hand, 12 wt% of silanized biostable glass filler group gave the lowest results (2.57 GPa). Significance. The silanization of glass fillers improved the properties of the glass as well as the properties of the composite. Silanization of bioactive glass may protect the glass from leaching at early stage of water storage. Crown Copyright (C) 2014 Published by Elsevier Ltd on behalf of The Academy of Dental Materials.

Protez kaide materyali olarak kullanılan polimerler ise geniş bir klinik kullanım alanına sahiptir; ancak fiziksel ve mikrobiyolojik özellikleri yeterli değildir. Bu nedenle camların biyoaktiviteleri ve antimikrobiyal özelliklerinin, polimerlerin yüksek dayanıklılık özellikleri ile birleştirilerek modifiye edilmiş yeni bir materyalin üretilmesi fikri ortaya çıkmıştır. Ancak polimerlerin organik yapısı ile camların inorganik yapısı arasında kimyasal bağlantının direkt sağlanamaması nedeniyle cam granüllerinin silan ile kaplanması yoluyla bu iki materyal arasında bağlantı sağlanılması düşünülmüştür. Çalışmamızın amacı oluşturulan hibrid materyalde meydana gelen fiziksel ve mikrobiyolojik değişiklikleri tespit etmek, silanizasyonun cam granülleri üzerindeki etkisini incelemek ve hibrid materyalde kullanılacak uygun orandaki cam oranını saptamaktır. Yaptığımız in vitro çalışmada modifiye materyallerin su emilimleri, yatay dayanıklılıkları, elastisite modülleri, tokluk değerleri, çözünürlükleri, yüzey sertlik değerleri, yüzey adezyon değerleri ve kalsiyum fosfat oluşumları incelenip değerlendirilmiştir. Çalışmamızda örnekler cam içermeyen PMMA olan kontrol grubu, silanize olmayan biyoaktif cam içeren grup, silanize biyoaktif cam içeren grup, silanize olmayan inert cam içeren grup ve silanize inert cam içeren grup olmak üzere beş ana grup altında incelenmiştir. Her ana grup kuru ile yaş olmak üzere ikiye ayrılmış ve %3, %6, %9, %12 oranında cam içeren gruplara bölünmüştür. Bu şekilde toplam 34 grup elde edilmiş ve grup başına 8’er adet (n=8/grup) olmak üzere toplam 272 adet (N=272) örnek hazırlanmıştır. 315-1000 µm granül büyüklüğüne sahip biyoaktif cam ve inert cam granülü kullanılmış olup, cam granüllerinin silanizasyon işlemi %2’lik 3-Metakriloksipropiltrimetoksisilan ile gerçekleştirilmiştir. Fiziksel testler için örnekler ISO 1567 standartlarına uygun olacak şekilde hazırlanmıştır. Su emilimi testi için kuru örnek grupları 37±0,20C’de inkübatörde distile su içerisinde bekletilmiştir. 1., 2., 3., 7., 14., 21., 30., 45., 60. günlerde örnekler solüsyondan çıkarılarak yüzde ağırlık değişimleri (%±SS) kaydedilerek istatistiksel analiz yapılmıştır (UNIANOVA, Dunnett T3; α=0.05). Üç nokta eğme testi, hem kuru hem de yaş örnek grupları için universal test cihazında 5±1 mm/dk hızında gerçekleştirilmiştir. Üç nokta eğme testi sonucunda yatay dayanıklılık (MPa±SS), elastisite modülü (GPa±SS), tokluk değerleri (kPa±SS) kaydedilerek istatistiksel analiz yapılmıştır (Kruskal-Wallis, Mann Whitney; α=0.05). Su emilimi testi tamamlanmış, üç nokta eğme testleri gerçekleştirilmiş olan örnekler; çözünürlük testi için 800C’de kurutma makinasında bekletilmiş; 1., 2., 3., 5., 7., 9. günlerde yüzde ağırlık değişimleri kaydedilerek (%±SS) istatistiksel analiz yapılmıştır (Kruskal-Wallis, Mann Whitney; α=0.05). Yüzey sertlik testi için her gruptan bir örnek seçilip üç farklı noktadan ölçüm yapılmış ve Vickers sertlik cihazı kullanılmıştır. Sertlik değerleri kaydedilerek (VHN±SS) istatistiksel analiz yapılmıştır (Kruskal-Wallis, Mann Whitney; α=0.05). Yüzey adezyon testi için örnekler 5x10x3 mm ebatlarında kesilerek otoklavda sterilize edilmiştir. C. albicans ve S. mutans’ın besiyerlerinde üremeleri sağlanmıştır. DNA izolasyon kiti kullanılarak mikroorganizmaların DNA izolasyonları gerçekleştirilmiştir. Elde edilen mikroorganizma DNA’ları, Fusayama-Meyer yapay tükürük solüsyonunda Real-Time PCR cihazı kullanılarak analiz edilmiştir ve elde edilen değerler kaydedilmiştir. TEM incelemesi için 10 mm çapında 3 mm kalınlığında %12 oranında silanize ve silanize olmayan biyoaktif cam granülü içeren disk şeklinde PMMA örnekleri hazırlanmış ve Kokubo solüsyonunda bekletilen örnekler 1., 3., 5., 7. günlerde x35, x50, x200 ve x750 büyütme altında incelenmiştir. Çalışmamızda elde edilen sonuçlara göre, silanize olmayan cam granüllerinde çözünme gerçekleşmiş ve kullanılan cam oranının artması ile birlikte çözünme değerlerinde artış izlenmiştir. Silanizasyon sonrası kullanılan cam oranının artmasıyla cam granülleri ile birlikte polimerin de çözünmesinin azaldığı tespit edilmiştir. Üç nokta eğme testi sonuçlarına göre kuru örneklerde kullanılan cam oranının artmasıyla yatay dayanıklılık ve tokluk değerlerinin azaldığı, elastisite modülü değerlerinin arttığı izlenmiştir. Yaş örneklerde ise %3, %6, %9 oranlarında cam içeren gruplarda bu değerlerde bir azalma izlenmemekle birlikte, %12 oranında cam içeren örneklerin dayanıklılık değerlerinde bir miktar azalma tespit edilmiştir. Materyallerin yüzey sertlik sonuçları incelendiğinde hem kuru hem yaş örneklerde kullanılan cam oranının artmasıyla birlikte değerlerde artış gözlemlenmiştir. C. albicans için yüzey adezyon sonuçları değerlendirildiğinde cam varlığının fungus tutulumunu azalttığı tespit edilmiştir. Silanizasyon neticesinde ise en düşük yüzey adezyon değerleri elde edilmiştir. S. mutans için yüzey adezyon sonuçları değerlendirildiğinde silanize olmayan cam varlığının bakteri tutulumunu arttırdığı, silanizasyon neticesinde ise tutulumun büyük oranda ortadan kalktığı izlenmiştir. Her iki mikroorganizma için en başarılı sonuçlar %9 silanize cam içeren gruplarda tespit edilmiştir. TEM incelemesi sonuçlarına göre, silanizasyon işleminin biyoaktif camın biyoaktivitesini engellemediği görülmüş olup, biyoaktivitenin daha yavaş ve kontrollü gerçekleştiği izlenmiştir. Çalışmamızda silanizasyon işleminin cam ile polimerin fiziksel ve mikrobiyolojik özelliklerini geliştirdiği tespit edilmiş, %9 oranında silanize biyoaktif cam veya inert cam ile modifiye edilmiş polimerlerin protez kaide materyali olarak kullanılabileceği sonucuna ulaşılmıştır. Kesin yargılar için uygulamaların in vivo ortamda ve klinik takipler sonucunda literatürdeki konu ile ilgili araştırma sayısının artması ile desteklenmesi gerekmektedir.Öğe Cam granül partiküllerinin protez kaide materyallerine fiziksel ve mikrobiyolojik etkilerinin araştırılması(Ege Üniversitesi, 2012) Oral, Onur; Kümbüloğlu, ÖvülÇalısmamızın amacı silanize ve non-silanize cam granülleri ile modifiye edilmis polimetil metakrilat (PMMA)'ta meydana gelen fiziksel ve mikrobiyolojik degisiklikleri tespit etmek, silanizasyonun cam granülleri üzerindeki etkisini incelemek ve modifiye materyalde kullanılacak uygun orandaki cam oranını saptamaktır. Çalısmamızda ISO 1567 standartlarına uygun sekilde hazırlanmıs PMMA bloklar %3, %6, %9, %12 oranında silanize ve silanize olmayan biyoaktif ve inert cam granülü ile karıstırılmıstır. Yapılan in vitro çalısmada modifiye materyallerin su emilimleri, çözünürlükleri, yatay dayanıklılıkları, elastisite modülleri, tokluk degerleri, yüzey sertlik degerleri, yüzey adezyon degerleri ve kalsiyum fosfat olusumları incelenip degerlendirilmistir. Elde edilen sonuçlara göre, silanizasyon sonrası tüm gruplarda artan cam oranı ile birlikte çözünürlük degerlerde azalma tespit edilmistir. Sulu ortamda bekletildiginde %12 cam oranına kadar fiziksel degerlerde kontrol grubu ile karsılastırıldıgında bir azalma meydana gelmemistir. Yüzey sertlik testinde; yüksek oranda cam varlıgı ve silanizasyon ile yüzey sertlik degerlerinin arttıgı, TEM incelemesi sonuçlarına göre ise cam granüllerinin silanizasyonu ile biyoaktivitenin daha kontrollü bir sekilde gerçeklestigi gözlemlenmistir.

Bu grup ilaçlar içersinde en etkili ve toksik etkisi en fazla olan doksorubisindir. Doksorubisin toksik etkilerinin önemli bir kısmını serbest oksijen radikalleri üzerinden gerçekleştirmektedir. Sıçanlar üzerinde invivo olarak yapılan bu çalışmada antioksidan bir madde olan resveratrolün bu toksik etkiyi azaltabileceği öngörülmüştür. Deney hayvanları; kontrol, tek doz 10 mg/kg intraperitoneal olarak resveratrol uygulanan, tek doz 20 mg/kg doksorubisin uygulanan, doksorubisin ile birlikte resveratrol uygulanan, tek doz doksorubisinden 3 gün sonra tek doz resveratrol uygulanan ve resveratrol çözücüsü olan DMSO uygulanan olmak üzere 6 gruba ayrıldı. Kardiotoksik etki histopatolojik olarak değerlendirildi. Grupların p53 ve eNOS pozitiflikleri immünohistokimyasal olarak çalışıldı, nitrit, nitrat düzeyleri araştırıldı ve elektron mikroskobik görüntülerle ince yapıda incelemeler yapıldı. Tüm tek doz doksorubisin alan gruplarda kaşektik düzeyde kilo kayıpları gözlenmiştir. Gruplar arasında kilo değişimleri açısından hayli anlamlı bir fark mevcuttur. Kalp kası hasarı en fazla yalnızca doksorubisin alan grupta gözlenmiş olup, en sık rastlanan bulgu nekrozdur. Kalp kası hasarlanması açısından gruplar karşılaştırıldığında kontrol grubu ile yalnızca doksorubisin alan grupta istatistiksel anlamda bir fark gözlenmiştir (p=0,02). Doksorubisin ile birlikte resveratrol ve doksorubisin uygulamasından 3 gün sonra resveratrol alan gruplar arasında fark gözlenmemiştir. eNOS pozitifliği endotel hücrelerinde ve perivasküler myositlerde gözlenmiştir. eNOS pozitifliği açısından kontrol grubu ile doksorubisin grubu karşılaştırıldığında; sınırda istatistiksel fark saptanmıştır. Doksorubisin ile doksorubisinden 3 gün sonra uygulanan resveratrol grubu arasında da anlamlı bir fark dikkati çekmiştir. p53 pozitif hücre yüzdesi açısından Grup 1 ve Grup 3 ile Grup3 ve Grup 5 arasında istatistiksel bir anlam bulunmuştur. Biyokimyasal olarak nitrit düzeylerinde; doksorubisinden üç gün sonra resveratrol verilen Grup 5’te, sadece doksorubisin uygulanan Grup 3'e göre hafif azalma görülmüştür. Elektron mikroskobik olarak doksorubisin verilen Grup 3’te yaygın myokardiyal dejenerasyon saptanmıştır. Ancak, doksorubisinden üç gün sonra resveratrol verilen Grup 5’te myokardiyal dejenerasyon alanlarında nispeten azalma olduğu gözlenmiştir. Sonuç olarak, 20 mg/kg tek doz intraperitoneal olarak doksorubisin uygulanması sıçanlarda kardiotoksisite oluşturmaktadır. Kardiotoksik etki, kalp kası hücrelerinde nekroz, yaygın apopitozis ve yaygın sitoplazmik vakuolizasyon ve yaygın miyokardiyal dejenerasyon ile karakterlidir. Doksorubisinin kardiotoksik etkileri serbest oksijen radikallerinin tetiklediği bir takım mekanizmalar ile oluşmaktadır. Bu süreçte eNOS aracılığı ile oluşturulan NO önemli bir rol oynamaktadır. Doksorubisine bağlı kardiotoksisitede p53 üzerinden çalışan apopitotik mekanizmalar söz konusudur. Bir antioksidan olan resveratrol uygulanan dozlarda doksorubisinin kardiotoksik etkisini önlemede düşük oranda etkili bulunmuştur.Öğe The effect of oral health on performance of athletes and sports injuries: a mini review(Tzaneio General Hospital, 2023) Oral, Onur; Rezaee, Zeinab; Nomikos, George; Rashidlamir, AmirOral health has a significant impact on athletes in terms of their general health, life quality, and performance. Recently, it has been found that oral health is affected by various factors such as nutritional habits, lifestyle routines, and so forth. These factors may also lead to negative impacts on the performance of athletes and even cause injuries although most athletes do not have awareness of it. Although few studies have been conducted regarding the relationship between oral health and its impact on athletes, poor oral health may cause negative effects on athletes including their life quality and performance. In addition, it may even cause sports injuries. There is a correlation between the impacts of poor oral health on athletes and their performance. To prevent poor oral health, there are many precautions such as changing nutritional habits and lifestyle and attending regular dental checks.Öğe The effect of physical activity on the psychological development of adolescent females(Tzaneio General Hospital, 2024) Oral, Onur; Rezaee, Zeinab; Nomikos, George N.; Ayca, Inci BanuIn this study, the positive contributions of regular physical activity habits to the social development and self-confidence of young women are emphasized. In the search for scientific literature for this review, data from the US National Library of Medicine (PubMed), MEDLINE, and SportDiscus were used, and the terms female adolescent health, self-confidence, physical activity, and self-esteem were used. The relevant literature has also taken its source from the research of relevant articles from reference lists derived from data searches. Self-esteem is defined as a person's general assessment of one's worth and is recognized as an important measure of psychological health. Since physical activity is any form of bodily movement performed to maintain or improve physical structure and general health, physical activity is thought to be associated with improved self-esteem in young adolescent females, and these two concepts are considered intertwined concepts. Regular exercise and physical activity are known to have numerous benefits for the physical and psychological development of young adolescent females. Exercise and sporting activities have been shown to help improve physical fitness, reduce depression, and increase self-confidence, and these positive effects help to create a psychological support system in young females. It is predicted that female adolescents who participate in physical activity during adolescence will have higher levels of self-esteem in adulthood compared to those who do not participate in physical activity. It is also accepted that female adolescents who develop physical activity habits during adolescence continue to carry positive sociopsychological and general health effects into adulthood.Öğe THE EFFECT OF SCORE COMPONENTS ON TOTAL SCORE IN THE INDIVIDUAL APPARATUS QUALIFICATION OF 1ST RHYTHMIC GYMNASTICS JUNIOR WORLD CHAMPIONSHIPS(Univ Ljubljana, Fac Sport, 2022) Tatlibal, Pinar; Kutlay, Emine; Oral, OnurThe study aims to determine the effect of the total score components on the total score and the differences between the score components in the 1st Rhythmic Gymnastics Junior World Championship individual apparatus qualification held in Moscow, Russian Federation, in2019. In this study, 1708 scores of 138 gymnasts from 61 countries were analyzed in all routines. For all routines, the effects of difficulty subgroup scores (D1-2, D3-4) on difficulty total scores (DTS), execution subgroup deduction scores (E1-2, E3-4-5-6) on execution total scores (ETS), and the effects of DTS and ETS on total scores (TS) were examined. Descriptive statistics, linear regression, and one-way ANOVA analysis were used. In linear regression analysis results, it was observed that the effect of DTS on TS was higher than the effect of ETS on TS in rope, ball, clubs, and ribbon routines. Among all apparatus, the effects of DTS and ETS on TS were observed as the highest in the clubs routines and the lowest in the rope routines. The effect of D3-4 on TS was higher than D-1(-2). The effect of deduction E-3(-)4-(5-6) on TS was higher than E1-2 (p<0.001). Statistically significant differences were found only between the DTS mean scores of the apparatus (p<0.000) analyzed with one-way ANOVA. This has led to a conclusion that the balance in the effect of TS components on TS scores will contribute to the integrity and the artistic impact of routines and also lead to better results, therefore more time should be devoted to rope and ribbon routines in the early stages of physical preparation.Öğe Effects of aerobic training on asprosin levels in adipose tissue of obese rats(Tzaneio General Hospital, 2023) Rezaee, Zeinab; Rashidlamir, Amir; Hosseini, Seyyed Reza Attarzadeh; Oral, OnurIntroduction. The asprosin hormone, which has been identified as a type of adipokine, is secreted from adipose tissue during fasting with a glucogenic effect on the liver. It increases glucose secretion into the blood, leading to a rise in blood insulin levels. In the hypothalamus, asprosin has an orexigenic role, helping to increase appetite which has a direct relationship with fat mass and obesity. The purpose of the present study was to evaluate the effect of aerobic exercise at different intensities on adipose tissue asprosin levels, thereby facilitating the determination of optimal training methods for controlling and treating obesity.Material and Methods. Male Wistar rats were randomly divided into four groups (n=10 per group) low (LOW), moderate (MOD), and high-intensity aerobic training (HIGH), and the control group (CON). The training intervention was conducted over 8 weeks, and surgical sampling from the rats' visceral adipose tissue was performed 48 hours after the final training session. Asprosin content of the adipose tissue was measured via ELISA.Results. Statistical comparisons between the groups revealed a difference in asprosin levels between the intervention groups and the control group (p=0.006). While low-intensity training already reduced asprosin levels significantly compared to controls and still was significant with intensified exercise levels, no further differences between moderate and high-intensity groups were visible anymore (p=0.410).Conclusions. Aerobic training at low, moderate, and high-intensity levels is effective in decreasing adipose tissue asprosin levels, which is accompanied by a reduction in fat mass and the treatment of obesity.Öğe Effects of BFR training in serum NRG-1 and IL-6 in overweight postmenopausal women(Tzaneio General Hospital, 2022) Rezaee, Zeinab; Javaheri, Seyed Ali Akbar Hashemi; Rashidlamir, Amir; Oral, Onur; Stavropoulos, EvangeliaIntroduction: Menopause is a noticeable period in women's life accompanied by some physiological and psychological changes leading to health conditions such as obesity, overweighing, cardiovascular, and other inflammatory diseases.Aim: Due to the importance of health cares in this period and the effectiveness of exercise training to attenuate the symptoms, we aimed to compare the effects of an emerging exercise tool by blood flow restriction in limbs on two public health-related cytokines, IL-6 (Interleukin-6) and NRG-1 (Neuregulin-1) in comparison with traditional training in overweight postmenopausal women.Materials-Methods: 30 overweight post-menopausal women were randomly assigned into BFR (Blood Flow Restriction), HI (High Intensity), LI (Low Intensity) groups (n=10) and performed eight weeks of concurrent training three days a week. Two lower body and two upper body exercises at 20%1RM (20% of one repetition Maximum) load for BFR and LI groups and at 80%1RM (80% of one repetition Maximum) load for HI group in addition to 20 minutes of aerobic training at the end. IL-6 and NRG-1 levels were measured before and after the eight weeks of training sessions.Results: Group differences in IL-6 levels were observed in BFR and HI groups (p=0.001 in both groups) but not in LI group (p=0.29). Differences between groups were significant between BFR and LI (p=0,00) and HI and LI (p=0.007) but not between BFR and HI (p=0.11). For NRG-1 levels, group differences were observed in all three groups (p=0.001), (p=0.003), (p=0.007) and the differences between groups for NRG-1 levels were significant between BFR and LI (p=0.001) and HI and LI (p=0.038) but not between BFR and HI (p=0.065).Conclusion: Low-intensity BFR training and high-intensity traditional resistance training are functioning similarly on the levels of IL-6 and NRG-1 in postmenopausal women and low-intensity training with BFR is more effective than low-intensity traditional training in this proposition.Öğe Effects of saliva and nasal secretion on some physical properties of four different resin materials(Medicina Oral S L, 2010) Kurtulmus, Huseyin; Kumbuloglu, Ovul; Aktas, Rahime Tuzunsoy; Kurtulmus, Aylin; Boyacioglu, Hayal; Oral, Onur; User, AtillaObjective: Aim of this study was to evaluate possible effects of saliva and nasal secretion on some physical properties, such as sorption, solubility, surface hardness and colour change on four different resin-based materials over a certain time period. Materials and Methods: A total of 128 disc-shaped specimens with a diameter of 50mm and thickness of 0.5mm were tested to evaluate sorption and solubility (ISO-1567). The specimens were stored in different solutions prior to testing. Surface hardness measurements were performed by using a Vickers hardness testing machine. A total of 20 cylinder-shaped test specimens with a diameter of 13 mm and thickness of 1 mm were prepared to evaluate colour change (Delta E). Analysis of variance was used to determine significant differences among groups. Paired t and Tukey Post-Hoc tests were performed to investigate significant differences among subgroups at all time intervals (p<0.05). Results: It was found that while the percentage absorption value at T7(7 days) of the auto-polymerizing (A) groups storaged in artificial saliva + nasal secretion were the highest (0.057 +/- 0.119), the percentage absorption value at T15(15 days) of the D groups storaged in artificial nasal secretion were the lowest (0.013 +/- 0.09). Besides, it was found that the percentage solubility value at T30(30 days) of visible ligth-cusing resin (VLC) groups storaged in artificial nasal secretion were the highest (0.016 +/- 0.003), and the percentage solubility value at T1(1 day) of the D groups storaged in distilled water were the lowest (0.01 +/- 0.02). While the highest hardness value was of T0(Dry) in group heat-polymerizing (H) (36.19 +/- 1.35), the lowest hardness value was of T0 in group D (9.83 +/- 2.48). When Delta E values analysed for each group, VLC group showed the highest values (23.78 +/- 5.05) (p<0.05), group D showed the lowest values (9.06 +/- 2.82) in time (between the T0 and T30). Conclusion: The new polyamide resin was observed to show better physical properties when compared with other materials.Öğe Evaluating the effect of oral health problems on athletic injuries in sports medicine(Tzaneio General Hospital, 2024) Tatlibal, Pinar; Oral, Onur; Rezaee, Zeinab; Nomikos, George N.; Stavropoulou, EvangeliaBackground: The study aims to investigate and evaluate the potential impacts of oral health problems on athletes' health and performance. Methods : This study was carried out with 149 female athletes over 18. Survey questions were prepared to evaluate the oral-dental health and injury status of the athletes. SPSS 22.0 program was used for statistical analysis. Correlation, ANOVA, and crosstabs analyses were carried out within the scope of the research. It was accepted as the level of significance (p<0.05). Results : A significant difference was found between the frequency of brushing the teeth of the participants in one day, whether there was tooth loss, and the reasons for tooth loss (p<0.05; p=0.046). There was a weak and strong positive correlation between the presence of oral and dental diseases of the participants and their difficulty in participating in the training due to muscle system problems (p<0.05; p=0.001). Conclusion: To maintain good health and performance, oral health is a crucial factor for all athletes. It is without a doubt that bad oral health directly influences the life quality and health of the athlete. For this reason, this study states that oral health is a key factor that should be taken proper care of for athletes to be in their total health and performance.Öğe Evaluation of Flexibility Capacity in Pediatric Overweight(Int Journal Applied Exercise Physiology, 2019) Oral, Onur; Cerit, Mesut; Erdogan, MuratChildhood is a severe threat to human health. There is a suggested relationship between overweight and physical fitness. the aim of the present study is to determine the association between overweight and flexibility in children. the sample consisted of individuals aged 10 and 12 ages. the sample includes of 105 students residing in Izmir. Body mass index (BMI) was calculated by using weight in kg unit and height in meter unit. Data analyzed by SPSS 11.0 package programs. Correlation and crosstabs analyses were also used in the research. It was determined that there was no relationship between body mass index values and the left and right flexibility values of the subjects. While obesity is linked to physical fitness in accordance with several studies and tests, the present study and previous studies state that flexibility and obesity have no meaningful association. Even though overweight constitutes physical difficulties for children, it does not cause a significant problem in terms of physical flexibility.Öğe The Evaluation of the Socio-Psychological Expectations of the Turkish Female Athletes(Int Journal Applied Exercise Physiology, 2019) Oral, OnurWoman who practice sports professionally are under constant pressure in terms of profession and cultural and social environment. Recently there is a breakthrough in terms of about female body. the studies reveal that today, females are just as involved in muscle gain behaviours as men. There is a new trend for female athletes to participate in non-lean sports. Traditional emphasis on slim female figures is changing in the modern world. Displaying muscular male and female figures became quite common on media lately. There is concrete argument that female athletes practicing non-lean sports experience less body dissatisfaction compared to lean sports athletes. Practice of non-lean sports is a new focus for females in terms of breaking down social body perceptions, proving their potentials, gaining status and improving confidence.Öğe A General Aspect of Platelet Rich Plasma(2015) Oral, Onur; Papavasılıou, Athanasios; Çabuk, Refik; Nomıkos, George; Özveren, Yeliz; Varol, Saadet Rana…Öğe The impact of both resistance and aerobic training on weight control management(Tzaneio General Hospital, 2023) Oral, Onur; Rezaee, Zeinab; Nomikos, George; Nomikos, Nikitas; Rashidlamir, AmirObesity has been appearing as a challenging health problem for years all over the world. For this reason, numerous treatment methods have been carried out, and among them, physical exercises have been underlined. While aerobic activities such as cycling and jogging assist in weight loss in obese patients, recent studies recommend that both anaerobic exercises are beneficial and should be combined. In the search for scientific literature related to this review, the US National Library of Medicine (PubMed) used MEDLINE and SportDiscus data, and the terms aerobic exercise, anaerobic exercise, physical exercise, and obesity were used. The relevant literature has also taken its source from the research of relevant articles from reference lists derived from data studies. Physical exercise has a significant role in treating and preventing obesity and overweight.
