Publication Open Access Protective and therapeutic effects of pyrrolidine dithiocarbamate in a rat tongue cancer model created experimentally using 4-nitroquinoline 1-oxide.(2020-11-01T00:00:00Z) Doğan, R; Hafız, AM; Gucin, Z; Ozer, OF; Ozturan, O; Yenigun, Alper; DOĞAN, REMZI; GÜCİN, ZÜHAL; ÖZER, ÖMER FARUK; YENİGÜN, ALPER; ÖZTURAN, ORHANPublication Open Access The Effect of Serum Bone Sialoprotein Levels on Tympanosclerosis(2020-07-01T00:00:00Z) Baki, Ahmet; Yildiz, Muhammet; ÖZER, Ömer Faruk; ÇAĞLAR, Hifa Gülru; ÖZER, ÖMER FARUK; ÇAĞLAR, HİFA GÜLRUObjective: This study aimed to investigate serum bone sialoprotein (BSP) levels in patients with tympanosclerosis (TS). Methods: We included into this study 24 patients with TS and 24 asymptomatic healthy volunteers. Our study consisted of two groups: TS group (n=24), comprising of patients who underwent surgery for chronic otitis media and had tympanosclerotic plaques; and a control group (n=24), comprising of healthy individuals without ear problems. The serum BSP levels were measured and the results were compared between the two groups. Results: In the TS group, there were 15 female and nine male patients. The ages of the females ranged from 24 to 54 years, while those of the males ranged from 34 to 55 years; the average age was 40.46 +/- 9.75 and 43.11 +/- 6.77, respectively. In the control group, there were 14 females and ten males. The ages of the females ranged from 30 to 48 years, while those of the males ranged from 27 to 47 years; the average age was 40.25 +/- 5.28 and 38.4 +/- 27.08, respectively. There was a statistically significant difference in BSP levels between the two groups (p=0.001). In addition, there was a moderate positive correlation between BSP and hearing levels. Conclusion: The serum BSP levels were higher in the TS group than in the control group and might have some effect on TS. Further studies on a large number of subjects using serum and tissue BSP levels should be designed to affirm the effects of BSP on TS.Publication Open Access Bezmialem COVID-19 PANDEMİSİNDE Hastalık / Hastane Yönetimi(2021-10-01T00:00:00Z) Selek, Şahabettin; Özer, Ömer Faruk; ÖZER, ÖMER FARUKPublication Open Access Assessment of serum endocan levels in patients with beta-thalassemia minor(2022-02-01T00:00:00Z) Zorlu, Mehmet; Ozer, Ömer Faruk; Karatoprak, Cumali; Kıskaç, Muharrem; Çakırca, Mustafa; ZORLU, MEHMET; ÖZER, ÖMER FARUK; KARATOPRAK, CUMALİObjective: Beta-thalassemia minor is a blood disease caused by a hereditary decrease in beta-globin synthesis, frequently leading to hypochromic microcytic anemia. Formerly called endothelial cell-specific molecule 1, endocan is a proteoglycan released by vascular endothelial cells in many organs. Our aim was to investigate the relationship between the beta-thalassemia minor patients and the healthy control group in terms of serum endocan level. Methods: The study was performed in a total of 80 subjects. They were divided into two groups, the beta-thalassemia minor group (n=40) and the healthy control group (n=40). Serum endocan levels, age, sex, body mass index value, and tobacco use data of these groups were compared. Results: No statistically significant difference was detected between the two groups in terms of age, sex, and body mass index values (p>0.05). Endocan levels were measured to be 206.85±88.1 pg/mL in the beta-thalassemia minor group and 236.1±162.8 pg/mL in the control group with no significant difference between the groups in terms of serum endocan levels (p>0.05). Conclusions: In our study, there was no change in endocan level in beta-thalassemia minor. This might be because serum endocan levels are affected by multi-factorial reasons. Serum endocan levels may be altered secondarily to decreased beta-globin chain, increased sympathetic activity due to anemia, or platelet dysfunction induced by oxidative stress in beta-thalassemia minor. Further multicenter studies involving more patients are necessary to demonstrate this.Publication Metadata only Total oxidant and antioxidant status and paraoxonase 1 levels of children with noncystic fibrosis bronchiectasis(2020-02-13T00:00:00Z) Gedik, AH; Çakir, Erkan; Vehapoğlu, Türkmen; Özer, ÖF; Kaygusuz, SB; ÇAKIR, ERKAN; VEHAPOĞLU TÜRKMEN, AYSEL; ÖZER, ÖMER FARUKPublication Open Access Dry Eye and Dry Nose Caused by the Effect of Allergic Rhinitis on Tear and Nasal Secretion Osmolarity.(2020-03-17T00:00:00Z) Elbay, A; Yenigun, A; Ozturan, O; Bayraktar, H; Ozer, Ömer Faruk; Dogan, R; YENİGÜN, ALPER; ELBAY, AHMET; ÖZDEM, ABDULLAH; ÖZER, ÖMER FARUK; DOĞAN, REMZI; ÖZTURAN, ORHANObjective: Allergic rhinitis is a type 1 hypersensitivity reaction of immunoglobulin E in the rhino-ocular mucosa. This study was planned to demonstrate in patients with allergic rhinitis to evaluate changes in tear, nasal secretions, and blood osmolarity compared to healthy individuals. Method: Forty allergic rhinitis patients, 25 patients with acute upper respiratory tract infections, and 26 healthy participants were included in the study. Positive patients with allergic symptoms and skin prick test results were included in the allergic rhinitis group. Tear, nasal secretion, and blood osmolarity values were examined for the 3 groups. Result: In patients with allergic rhinitis, tear and nasal secretion osmolarity values were significantly higher in patients with acute upper respiratory tract infections and those of the healthy participants (P ¼ .001, P ¼ .038). In blood osmolarity measurements, there was no statistical difference between the groups (P ¼ .489). In patients with allergic rhinitis, Schirmer test results were significantly shorter than patients who had acute upper respiratory tract infection and those of the healthy participants (P ¼ .001, P ¼ .001). Patients with allergic rhinitis and acute upper respiratory tract infections had significantly shorter Schirmer test results than in healthy participants (P ¼ .001, P ¼ .001). Conclusion: Tear osmolarity was increased in allergic rhinitis patients, and this was thought to lead to dry eye findings. In the presence of allergic rhinitis, nasal secretions were found more hyperosmolar than tears. Nasal secretion osmolarity was higher in allergic rhinitis patients than in patients with acute upper respiratory tract infections and control group.Publication Metadata only The changes of oxidative stress markers and vitamin E in patients with diabetes using SGLT2 inhibitors(2023-01-01) Buyukaydin B.; ÖZER Ö. F.; ÖZDER A.; YILDIZ C.; BÜYÜKAYDIN, BANU; ÖZER, ÖMER FARUK; ÖZDER, ACLAN; YILDIZ, CANERObjectives: This study aimed to research the diversities of vitamin E and oxidative stress parameters related to sodium-glucose transport protein 2 (SGLT2) inhibitor use by type 2 diabetes mellitus (T2DM) patients. Methods: This observational clinical study collected data from 67 T2DM patients (55.7±9.3 years, 46% female). Vitamin E, total oxidant status (TOS), total antioxidant status (TAS), total thiol, native thiol, myeloperoxidase, and catalase levels were evaluated. The TOS/TAS ratio was calculated as the oxidative stress index. Correlations of the parameters to each other and differences based on SGLT2 inhibitor use were recorded. Results: The mean hemoglobin A1c was 7.1 (5.5–13.1). SGLT2 inhibitors (all combinations) were used by 25 patients (37.3%). The mean level of vitamin E was 6 (3.6–9.8) mg/L. There was a positive correlation between vitamin E and low-density lipoprotein cholesterol (p<0.001). While there was no significant correlation between vitamin E and all included oxidative stress parameters, the level of vitamin E was statistically lower in patients using pioglitazone (p=0.036) and statins (p<0.001). In patients using SGLT2 inhibitors, fasting glucose, triglycerides, alanine aminotransferase, and the spot urine protein/creatinine ratio were significantly lower, and the mean TAS was higher (p<0.05). Conclusion: While no differences were observed in vitamin E and other oxidative parameters related to SGLT2 inhibitor use, the increase in TAS provides motivation for further research investigating the antioxidant properties of these inhibitors.Publication Metadata only Decreased Levels of Fasting Serum Leptin in Patients With Schizophrenia: A Case-Control Study(2020-01-01T00:00:00Z) Şahbaz, Çiğdem; Kurtulmuş, Ayşe; Kırkpınar, İsmet; Gülöksüz, Sinan; ÖZER, ÖMER FARUKPublication Open Access Serum Melatonin Levels in Patients with Sudden Sensorineural Hearing Loss(2020-07-01T00:00:00Z) Baki, Ahmet; ÖZER, Ömer Faruk; Yildiz, Muhammet; KÖKTAŞOĞLU, FATMANUR; ÖZER, ÖMER FARUK; KÖKTAŞOĞLU, FATMANURObjective: This study aimed to investigate the serum melatonin levels of patients with idiopathic sudden sensorineural hearing loss (ISSNHL). Methods: This study enrolled 22 patients with ISSNHL and 22 asymptomatic healthy volunteers. The subjects underwent pure tone audiometry and serum melatonin levels were measured.
