    Total antioxidant status and oxidative stress in recurrent aphthous stomatitis
    (2016-03-01) TUGRUL, Selahattin; Kocyigit, ABDÜRRAHİM; Dogan, REMZİ; Eren, SABRİ BAKİ; SENTURK, EROL; Ozturan, ORHAN; OZAR, Omer Faruk; KOÇYİĞİT, ABDÜRRAHİM; DOĞAN, REMZI; EREN, SABRİ BAKİ; ŞENTÜRK, EROL; ÖZTURAN, ORHAN; ÖZER, ÖMER FARUK
    BackgroundRecurrent aphthous stomatitis is an idiopathic, chronic, recurrent inflammatory disease of the oral mucosa. It is thought that oxidative stress caused by systemic inflammation plays a basic role in the etiopathogenesis of recurrent aphthous stomatitis. The aim of this study is to review oxidative status and DNA damage in recurrent aphthous stomatitis.

    Comparison of the biochemical and radiological criteria for lumbar disc degeneration
    (2018-09-01) Seyithanoglu, MEHMET HAKAN; Kitis, SERKAN; Ozer, Omer Faruk; Kocyigit, ABDÜRRAHİM; DÜNDAR, Tolga; Papaker, Meliha Gundeg; SEYİTHANOĞLU, MEHMET HAKAN; KİTİŞ, SERKAN; ÖZER, ÖMER FARUK; KOÇYİĞİT, ABDÜRRAHİM
    Background: The relationship between radiological degeneration criteria on lumbar magnetic resonance imaging (MRI) and both the keratan sulfate (KS) and chondroitin sulfate (ChS) levels was examined in disc material taken from patients undergoing lumbar disc herniation (LDH) surgery. To examine whether the biochemical and radiological degeneration criteria testing the reliability of radiological degeneration findings agreed and to evaluate the contribution of the KS/ChS ratio to disc form (protruding or extruding).

    Oxidative/antioxidative status, lymphocyte DNA damage, and urotensin-2 receptor level in patients with migraine attacks
    (2018-01-01) YIGIT, Mehmet; SOGUT, Ozgur; TATAROGLU, Ozlem; YAMANOGLU, Adnan; YIGIT, Eda; Guler, ERAY METİN; Ozer, Omer Faruk; Kocyigit, ABDÜRRAHİM; GÜLER, ERAY METİN; ÖZER, ÖMER FARUK; KOÇYİĞİT, ABDÜRRAHİM
    Background: The present study investigated the potential roles of plasma lymphocyte DNA damage, the urotensin-2 receptor (UTS2R), and oxidative changes in patients with varying degrees of migraine-related disability who were in the ictal phase and presented to our emergency department. Methods: This study enrolled 40 consecutive adult patients with migraine attack and 40 age- and sex-matched healthy controls. The same health care professional determined the headache-related disability of each patient’s migraine attack using the Migraine Disability Assessment Scale (MIDAS); patients were divided into three groups based on MIDAS score. Plasma lymphocyte DNA damage; UTS2R, malondialdehyde (MDA), and catalase (CAT) levels; total oxidant status (TOS); total antioxidant status (TAS); and the oxidative stress index (OSI) were used as predictors of early oxidative changes. Results: Plasma lymphocyte DNA damage, TOS, MDA levels, and OSI values were significantly higher in patients with migraine compared to controls. Conversely, TAS and CAT and UTS2R levels were markedly lower in patients with migraine compared to controls. Comparisons of the patient groups by MIDAS score revealed significant differences in plasma lymphocyte DNA damage and CAT levels but no differences in TOS, MDA levels, OSI, TAS, or UTS2R levels. MIDAS scores were positively correlated with the degree of lymphocyte DNA damage, but neither of these factors was significantly related to CAT levels. Conclusion: The present data suggest that lymphocyte DNA damage and changes in oxidative/ antioxidative status may reflect an enhanced oxidative damage and an ineffective antioxidant defense system in migraineurs during headache attacks. In addition, lymphocyte DNA damage levels may be an indicator of the degree of migraine-related disability as assessed by MIDAS score.

    Oxidative Stress Status in Childhood Obesity: A Potential Risk Predictor
    (2016-10-13) Kılıç, Elif; Ozer, Omer Faruk; Erek, Aybala Toprak; ERMAN, HAYRİYE; Torun, EMEL; AYHAN, Siddika Kesgin; Caglar, HİFA GÜLRU; Selek, Sahbettin; Kocyigit, ABDÜRRAHİM; ÖZER, ÖMER FARUK; TORUN, EMEL; ÇAĞLAR, HİFA GÜLRU; SELEK, ŞAHABETTİN; KOÇYİĞİT, ABDÜRRAHİM
    Background: Childhood obesity characterized by excessive fat in the body is one of the most serious health problems worldwide due to the social, medical, and physiological complications. Obesity and associated diseases are triggering factors for oxidative stress and inflammation. The aim of this study was to explore the possible association between childhood obesity and inflammatory and oxidative status. Material/Methods: Thirty-seven obese children and 37 healthy controls selected from among children admitted to BLIND University Paediatrics Department were included in the study. Anthropometric measurements were performed using standard methods. Glucose, lipid parameters, CRP, insulin, total oxidant status (TOS), total anti-oxidant status (TAS) levels, and total thiol levels (TTL) were measured in serum. HOMA index (HOMA-IR) were calculated. The differences between the groups were evaluated statistically using the Mann-Whitney U test. Results: Body mass index was significantly higher in the obese group (median: 28.31(p<0.001). Glucose metabolism, insulin, and HOMA-IR levels were significantly higher in the obese group (both p<0.001). Total cholesterol, HDL cholesterol, LDL cholesterol, and triglyceride levels were significantly higher in the obese group (p<0.001). TAS (med: 2.5 µmol Trolox eq/L (1.7–3.3)) and TOS (med: 49.1 µmol H2 O2 eq/L (34.5–78.8)) levels and TTL (med: 0.22 mmol/L (0.16–0.26)) were significantly higher in the obese group (p=0.001). CRP levels showed positive correlation with TOS and negative correlation with TTL levels (p=0.005, r=0.473; p=0.01, r=–0.417; respectively). TTL levels exhibited negative correlation with TOS levels (p=0.03, r=–0.347). Conclusions: In conclusion, obese children were exposed to more oxidative burden than children with normal weight. Increased systemic oxidative stress induced by childhood obesity can cause development of obesity-related complications and diseases. Widely focussed studies are required on the use of oxidative parameters as early prognostic parameters in detection of obesity-related complications
