Article Citation - WoS: 30Citation - Scopus: 33Targeting the Panoptosome With 3,4-Methylenedioxy Reduces Panoptosis and Protects the Kidney Against Renal Ischemia-Reperfusion Injury(Taylor & Francis, 2022) Uysal, Erdal; Dokur, Mehmet; Küçükdurmaz, Faruk; Altınay, Serdar; Polat, Sait; Batçıoğlu, Kadir; Sezgin, EfeObjectıves: The objectives of this study were a) to investigate the effect of targeting the PANoptosome with 3,4-methylenedioxy-β-nitrostyrene (MNS) on PANoptosis in the Renal ischemia-reperfussion (RIR) model b) to investigate the kidney protective effect of MNS toward RIR injury. Methods: Thirty-two rats were divided into four groups randomly. The groups were assigned as Control, Sham, DMSO (dimethyl sulfoxide) and MNS groups. The rats in the MNS group were intraperitoneally given 20 mg/kg of MNS 30 minutes before reperfusion. 2% DMSO solvent that dissolves MNS were given to the rats in DMSO group. Left nephrectomy was performed on the rats under anesthesia at the 6th hour after reperfusion. Glutathione peroxidase (GPx), malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD) and 8-Okso-2′-deoksiguanozin (8-OHdG) levels were measured. Immunohistochemical analysis, electron microscopic and histological examinations were carried out in the tissues. Results: Total tubular injury score was lower in the MNS group (p < 0.001). Caspase-3, Gasdermin D and MLK (Mixed Lineage Kinase Domain Like Pseudokinase) expressions were considerably decreased in the MNS group (p < 0.001). Apoptotic index (AI) was found to be low in the MNS group (p < 0.001). CAT and SOD levels were higher in the MNS Group (p = 0.006, p = 0.0004, respectively). GPx, MDA, and 8-OH-dG levels were similar (p > 0.05) in all groups. MNS considerably improved the tissue structure, based on the electron microscopic analysis. Conclusıons: Our results suggested that MNS administrated before the reperfusion reduces pyroptosis, apoptosis and necroptosis. These findings suggest that MNS significantly protects the kidney against RIR injury by reducing PANoptosis as a result of specific inhibition of Nod-like receptor pyrin domain-containing 3 (NLRP 3), one of the PANoptosome proteins.Article Citation - WoS: 1Is Routine Histopathological Gallbladder Examination Necessary After Cholecystectomy? Evaluation of the Results of 1366 Cholecystectomy Specimens in Single Center(Düzce Üniversitesi, 2017) Uysal, Erdal; Sezgin, Efe; Bakır, Hasan; Gürer, Ahmet; Sökücü, MehmetObjective: It was aimed to evaluate the results of routine histopathological examination after cholecystectomy and to investigate the necessity of routine histopathologic examination after cholecystectomy. Methods: The study was designed retrospectively. One thousand three hundred sixty six patients who underwent laparoscopic and open cholecystectomy at Private Sani Konukoglu Hospital with pre-diagnosis of benign gallbladder disease between November 2011 and May 2017 were included in the study. Patients' demographic data, pathologic results, macroscopic appearance of the specimen, and cancer staging were recorded. The distribution and frequency of pathologic diagnoses and the prevalence of incidental gallbladder cancer (GBC) were evaluated. Pathologic findings were compared in terms of age groups and gender relations. Results: The number of patients included in the study was 1366. Diagnosed with chronic cholecystitis patients were 1,303 (95%), 39 (3%) with acute cholecystitis, 7 (0.5%) with gallbladder cancer, and 17 (1.5%) with other diagnoses of the patients. Statistical significance was found between the groups in terms of the mean age (p = 0.0002). Comparisons between groups in terms of cholesterolysis were statistically significant (p = 0.0003). There was a significant relationship between mucosa atrophy and gender (p = 0.001). Conclusions: The histopathological spectrum of gallbladder is quite extensive. Incidental GBC may not be detected by preoperative imaging methods. Incidental GBC are usually asymptomatic. T2, T3 and T4 GBC were also encountered in our study. All of these patients need additional operations. In the absence of routine histopathologic examination, metastatic advanced GBC may be encountered because no treatment plans could make. Thus, we do recommend routine histopathological examination.Article Citation - WoS: 2Citation - Scopus: 2Evaluation of Hemocytometer Parameters as Potential Biomarkers in Benign Multinodular Goiter and Papillary Thyroid Carcinoma(Kowsar Publishing Company, 2017) Uysal, Erdal; Ceylan, Seyit Mehmet; Sezgin, Efe; Bakir, Hasan; Gurer, Ahmet Orhan; Aksoy, Basar; Bastemir, MehmetBackground: Hemocytometer parameters can be important biomarkers for some types of cancers and diseases. There is a need to evaluate their biomarker potential in thyroid diseases. Objectives: The current study aimed at contributing to potential biomarker researches to diagnose papillary thyroid carcinoma (PTC) and benign multinodular goiter (BMG), evaluate the role of these markers to determine the PTC characteristics and contribute to clarification of controversial issues. Methods: The study was designed as a retrospective observational study. The study included 389 patients who underwent total thyroidectomy at private Sani Konukoglu hospital (Sanko University, School of Medicine, Gaziantep, Turkey) due to BMG or PTC diagnosis from November 2011 to May 2017. The study subjects were divided into 3 groups. Groups 1, 2, and 3 were subjects with BMG, PTC, and the control, respectively. The comparisons were made among the groups in terms of hemocytometer parameters. In the group with the thyroid papillary carcinoma diagnosis, the relationship between the hemocytometer parameters and the bilateral tumor presence, single-sided multicentrite, and tumor diameter (size) were investigated. Results: Red cell distribution width (RDW) levels were 15.50 +/- 2.39, 15.68 +/- 2.16, and 12.5 +/- 1.51 in the BMG, PTC, and control groups, respectively. Mean platelet volumes (MPV) were 7.97 +/- 1.19, 8.05 +/- 1.20, and 7.23 +/- 1.39 in the BMG, PTC, and control groups, respectively. MPV and RDW values were significantly lower in group 3 compared with the groups 1 and 2 (P < 0.0001). Plateletcrit (PCT) values were 0.22 +/- 0.05, 0.23 +/- 0.06, and 0.19 +/- 0.05 in the BMG, PTC, and control groups, respectively. PCT was significantly lower in the group 3 compared with the groups 1 and 2 (P = 0.0001). In PTC group, no significant relationship was observed between any of the examined hematological parameters in terms of multicentric and bilateral tumor presence. Conclusions: RDW, MPV, haemoglobin content, and PCT were significantly higher in the BMG and PTC groups. This increase was not specific for either of the 2 groups. No significant difference was found between any of the hemocytometer parameters and the multicentricity and bilaterality of PTC. But, a possible correlation was observed between activated partial thromboplastin time (aPTT), hemoglobin content, and tumor size.Article Citation - WoS: 87Citation - Scopus: 94Factors Related To Recurrence of Idiopathic Granulomatous Mastitis: What Do We Learn From a Multicentre Study?(John Wiley and Sons Inc., 2018) Uysal, Erdal; Soran, Atilla; Sezgin, Efe; Granulomatous Mastitis Study GroupBackground: Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory disease of the breast with unknown aetiology. Its treatment is controversial and the recurrence rate is high. The objectives of this study were to examine the demographic, sociocultural and clinical characteristics observed among a large cohort of IGM patients from Turkey and to identify factors related to the recurrence of IGM. Methods: The study was designed as a multicentre retrospective study including 22 breast centres in Turkey. A total of 720 IGM patients are included in the study. Patient data were obtained from the patient's files and electronic records based on the study protocol. Patients’ demographic, clinical, radiological, treatment and recurrence of IGM related characteristics were recorded. Results: Our results revealed a statistically significant association between IGM recurrence and history of pregnancy, breastfeeding, breast infection and smoking (P < 0.05). Having a chronic systematic disease, oral contraceptive, analgesic and herbal medicine consumptions, treatment choice, education, place of birth and current residence were not found to be associated with IGM recurrence (P > 0.05). Conclusion: Our findings show that history of pregnancy, breastfeeding, breast infection and smoking were the risk factors for IGM recurrence. As current treatment methods did not affect IGM recurrence, recurrence-related factors, such as breast infection and smoking, should be considered to eliminate while focusing on less invasive local treatment research.
