Article Citation - WoS: 12Citation - Scopus: 11Protective Effect of Astaxanthin on Histopathologic Changes Induced by Bisphenol a in the Liver of Rats(Univ Agriculture, Fac veterinary Science, 2024) Karabekir, Seda Cetinkaya; Gultekin, Burcu; Ayan, Ilknur Cinar; Savas, Hasan Basri; Cuce, Gokhan; Kalkan, SerpilBisphenol A (BPA) has several potential uses, including in polycarbonate plastics and epoxy resins, which could expose humans to it. Recognized for its hepatotoxicity and ability to accumulate in organs. We prompted this study to explore the hepatoprotective potential of astaxanthin (ASTX), an antioxidant against BPA toxicity. We used 32 male Wistar Albino rats and randomly assigned them as: Control, Sham (olive oil), BPA, and BPA+ASTX. At the end of the experiment, Native Thiol, Total Thiol, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured in serum samples. Histopathological scoring was performed to evaluate the changes caused by ASTX in the liver. Caspase 3 and caspase 9 expression in liver tissues was demonstrated immunohistochemically and by PCR. Collagen I (COL1A1) and collagen III (COL3A1) mRNA levels were measured by PCR in the tissue samples. The BPA group showed elevated AST and ALT with decreased Thiol levels. ASTX administration reversed these changes as observed by reduced AST and ALT levels and increased Thiol levels. Histopathology indicated increased liver damage and fibrosis in the BPA group which were alleviated in the BPA+ASTX group. Gene expression analyses revealed upregulated COL1A1 and COL3A1 in BPA, which was downregulated with ASTX. Immunohistochemistry and PCR confirmed BPA-induced caspase 3 and caspase 9 expression, which were attenuated by ASTX. This study underscores ASTX's hepatoprotective efficacy against BPA-induced hepatotoxicity which ultimately attributed to its antioxidant and antiapoptotic properties. Consequently, ASTX emerges as a promising therapeutic agent for preventing and treating BPA-related liver diseases.Article Evaluation of Thiol/Disulfide Homeostasis and Ischemia Modified Albumin as Potential Markers for Periodontitis(BMC, 2025) Karci, Bilge; Savas, Hasan BasriBackground The current study aimed to assess the impact of periodontitis on oxidative stress parameters by examining serum total antioxidant capacity (TAS), total oxidant status (TOS), oxidative stress index (OSI), thiol/ disulfide homeostasis and ischemia modified albumin (IMA). Methods The study had 90 participants, categorized into 3 groups: Group 1: Periodontally healthy; Group 2: Stage II Grade B periodontitis; Group 3: Stage III and IV Grade B periodontitis. Demographic and periodontal variables were assessed. The levels of serum TAS, TOS, OSI, IMA, and thiol/disulfide were assessed. Results No significant differences in sex and age were detected among the groups (p > 0.05). When compared to Group 1, all clinical measurements were statistically significantly greater in Group 3 (p < 0.05). Statistical analysis revealed no significant differences in serum TAS, TOS, and OSI levels among the groups (p > 0.05). The highest serum IMA value was observed in Group 3 (p = 0.037), whereas native thiol (p = 0.00), total thiol (p = 0.00) and disulfide values (p = 0.023) were highest in Group 1. Conclusions These findings indicate that thiol/disulfide homeostasis and IMA could hold promise as a potential biomarker of inflammation in periodontitis.Article Examining the Angiogenic and Antioxidant Effects of Various Paracetamol Dosages Using a Chorioallantoic Membrane Model(Yuzuncu Yil University Tip Fakultesi, 2025) Savaş, H.B.; Batur, T.Introduction: Paracetamol is one of the most popular and frequently used analgesic and antipyretic medications in the world. It was aimed at investigating the effects of paracetamol on angiogenesis and oxidative stress markers in the in vivo chorioallant oic membrane model (CAM). Materials and Methods: The 40 fertilized chick eggs were used in the experiment. The four groups were as; the control group (n = 10), 10-6 M bevacizumab group (n = 10), 10-4 M paracetamol group (n = 10) and 10-5 M paracetamol group (n = 10). Stereoscopic microscopy was used to assess angiogenesis on the window that was opened on the eggshell. Total oxidant capacity (TOS), total antioxidan t capacity (TAS), and oxidative stress index (OSI) were analyzed in albumen specimens. The scoring methodology described in earlier research publications was used to determine and compare the average score values. One-way analysis of variance and the post hoc Tukey test were performed to assess oxidative stress markers between the groups. Results: The bevacizumab group demonstrated a strong anti-angiogenic effect, but the control group and both paracetamol groups showed no anti-angiogenic effect. Paracetamol increased TAS values at a 10-4 M concentration. The bevacizumab group's TOS and OSI values were significantly higher compared to the control group. Conclusion: Paracetamol is used by a lot of people; healthy blood vessel growth and the balance between oxidants and antioxidants are important. The important result of this study is that paracetamol has strong antioxidant effects and no anti-angiogenic effects. © 2025, Van Medical Journal.

The content of BM may be influenced by maternal body mass index (BMI). The aim of this study was to investigate the effect of maternal weight on BM and cord blood iodine concentrations, growth-related hormones, infant anthropometric measurements. A total of 84 mother-infant pairs participated. Levels of leptin, adiponectin and insulin-like growth factor-I (IGF-I) in postnatal BM and cord blood were analysed by enzyme-linked immunosorbent assay (ELISA), iodine by Sandell-Kolthoff reaction. Dietary iodine intake of women was determined by food frequency questionnaire, and anthropometric measurements of infants at birth and 3 months were evaluated. Dietary iodine intake was found to be similar in normal weight (NW) and overweight/obese (OW/OB) women (p > 0.05). Breast milk iodine concentration (BMIC) was 17.4 mu g in NW, 18.2 mu g in OB/OW women. Adiponectin in cord blood and IGF-I in BM were higher OB/OW than NW women (p < 0.05). Positive correlations were found between the infant birth weight and adiponectin in BM, between the infant body weight at 3 months and leptin and adiponectin in BM, between the infant birth head circumference and IGF-I in BM (p < 0.05). In multiple linear regression model, leptin and adiponectin in BM had a positive effect on infant body weight (p < 0.05). Maternal BMI may influence infant body weight via leptin and adiponectin in BM and infant head circumference via IGF-I. No relationship was found between maternal BMI and iodine levels and anthropometric measurements of the infant. Longitudinal studies are recommended to understand the effect of BMIC on growth.Article Citation - WoS: 5Citation - Scopus: 4Thiol–disulfide balance and trace element levels in patients with seasonal allergic rhinitis(African Health Sciences, 2022) Savas, Hasan Basri; Gunizi, HuseyinAbstract Background: The prevalence of allergic diseases is gradually increasing worldwide. The most common such allergic disease is allergic rhinitis (AR). Objective: The present study investigated the possible relationship between seasonal AR and the thiol-disulfide balance and zinc and copper levels in adult individuals. Study Design and Methods: 130 male and female adults were included in the study. The participants’ serum thiol-disulfide balance and zinc and copper levels were measured spectrophotometrically using commercial kits. Statistical significance was accepted as p < 0.05 between the groups. Results: The serum copper (p = 0.001), native thiol (p = 0.006), reduced thiol (p < 0.001), and thiol oxidation reduction ratio (p < 0.001) levels were significantly lower in the seasonal AR group than in the control group. Conclusion: In AR patients, the low level of copper, which is an important trace element, the deterioration of the thiol-disulfide balance, which represents a unique indicator of the oxidant-antioxidant balance, the increased disulfide level caused by oxidative stress, and the decreased native thiol level can all serve as important biochemical markers.Book Article Citation - WoS: 1Citation - Scopus: 1The Ameliorative Effects of Hesperidin in Rats Developed Hepatotoxicity With Deltamethrin(Mashhad Univ Med Sciences, 2025) Karabekir, Seda Cetinkaya; Sozen, Mehmet Enes; Ayan, Ilknur Cinar; Savas, Hasan Basri; Cuce, Gokhan; Kalkan, SerpilObjective(s): Deltamethrin (DLM) is a widely used insecticide in agriculture; however, exposure to it can lead to serious health problems. This study aimed to evaluate the protective effects of hesperidin (HSP), a natural antioxidant, against DLM-induced liver toxicity. Materials and Methods: Thirty-two male Wistar Albino rats (250-300 g, 4 months old) were divided into four groups. The control group received 1 ml of corn oil via oral gavage for 30 days. The DLM group received 1.28 mg/kg DLM in corn oil for 30 days. The DLM+HSP 100 mg/kg and DLM+HSP 300 mg/kg groups received 1.28 mg/kg DLM followed by 100 mg/kg or 300 mg/kg HSP in distilled water, respectively, 30 min after DLM administration for 30 days. Liver tissues were examined histopathologically. Masson's trichrome staining and PCR assessed fibrosis. Caspase 3 and 9 expressions in liver tissues were determined by immunohistochemistry and PCR. Biochemical analyses were conducted on serum samples. Results: HSP supplementation led to a dose-dependent decrease in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. DLM exposure decreased antioxidant capacity, while HSP supplementation increased it dose-dependently. Histopathological evaluations showed increased liver damage in the DLM group, while HSP administration reduced liver toxicity. Masson's trichrome staining and analysis of collagen I (COL1A1) and collagen III (COL3A1) gene expression revealed increased fibrosis in the DLM group, which was attenuated with HSP treatment. Conclusion: The potential prevention of DLM-induced liver toxicity and apoptosis by HSP may be an alternative protective strategy.Article Citation - WoS: 5Citation - Scopus: 5Comparison of Growth Factor Levels in Injectable Platelet-Rich Fibrin Obtained From Healthy Individuals and Patients With Chronic Periodontitis: a Pilot Study(BMC, 2024) Savas, Hasan Basri; Karci, BilgeBackground This study aimed to assess and compare the concentrations of growth factors, white blood cells (WBCs), and platelets in injectable platelet-rich fibrin (i-PRF) derived from people with healthy periodontal conditions and those with chronic periodontitis.Methods Venous blood samples were obtained from 30 patients diagnosed with chronic periodontitis (test group) and 30 participants with healthy periodontal conditions (control group). The i-PRF was then acquired from centrifuged blood. The growth factors (VEGF, IGF-1, TGF-beta 1, PDGF-BB and EGF) released from the i-PRF samples were compared between groups with ELISA testing. The amounts of WBCs and platelets were also compared.Results No significant differences in the concentrations of growth factors were found between the groups (the mean values for the control and test groups were, respectively: IGF: 38.82, 42.46; PDGF: 414.25, 466.28; VEGF: 375.69, 412.18; TGF-beta 1: 21.50, 26.21; EGF: 138.62, 154.82). The test group exhibited a significantly higher WBC count than the control group (8.80 vs. 6.60, respectively). However, the platelet count did not show a statistically significant difference between the groups (control group 242.0 vs. test group 262.50). No significant correlation was observed between WBC count and growth factor level in either group.Conclusions The growth factor levels in i-PRFs did not exhibit significant difference between the two groups. This suggests that the levels of these growth factors may be unaffected by the periodontal disease.Article Anti-Angiogenic and Oxidant Effects of Monosodium Glutamate at Different Concentrations in Chorioallantoic Membrane Model(Muğla Sıtkı Koçman Üniversitesi, 2023)Monosodium glutamate (MSG) is a flavor-enhancing food additive. MSG exposure is rising day by day because of the high commercial food consumption. MSG exposure causes damage to various tissues and organs. The aim of this study is to investigate the effects of MSG on angiogenesis and oxidant-antioxidant balance. Three different concentrations of MSG (10-4 M, 10-5 M, and 10-6 M), control, and the bevacizumab (10-6 M) were prepared and placed on the chorioallantoic membrane (CAM) of the embryos. Albumen was taken from the embryos before and after the experiment. Angiogenesis was investigated through the window that was opened on the eggshell. Angiogenesis was found to be normal in the control and 10-6 M MSG group (average score: 0.3). Anti-angiogenic effects were moderate in the 10-5 M MSG group (average score: 0.5) and in the 10-4 M MSG group (average score: 0.7), and strong in the bevacizumab group (average score: 1.1). According to our results, MSG shows anti-angiogenic properties in higher doses. MSG increased oxidative stress. According to the results of our research, it is seen that MSG inhibits angiogenesis in a dose-dependent manner in the CAM model and may cause an increase in oxidative damage by disrupting the oxidant-antioxidant balance. Since no previous study has been found in the literature regarding the effects of MSG on angiogenesis and oxidant-antioxidant balance in the CAM model, we think our results will fill an important gap in the literature.Article Citation - WoS: 1Citation - Scopus: 2Effects of Trimetazidine on Oxidant-Antioxidant Balance and Angiogenesis; an in Vivo Experimental Study(BMC, 2025) Kayan, Fethullah; Savas, Hasan BasriBackground We evaluated the effects of trimetazidine (TMZ) on the oxidative-antioxidative balance and angiogenesis in an in vivo experimental model. This study aims to evaluate the effects of trimetazidine on angiogenesis through histological analysis and to assess its impact on oxidative-antioxidative balance through biochemical measurements. Methods In this study, Ross 308 breed chicken eggs (n = 40) were used, and embryos were divided into four distinct groups. On the eighth day of incubation, the vascular density of the embryos was examined. Following the assessment of vascular development, 4-5 mL of albumin was collected via syringe to measure oxidative stress markers. Each group consisted of 10 embryos, with a total of 40 embryos used in the study. The groups were organized as follows: Control Group (CG), Bevacizumab Group (BC), Trimetazidine 10(-)(4) Group, and Trimetazidine 10(-)(5) Group. Results When the total oxidative capacity (TOC) levels were compared among the groups, the bevacizumab group exhibited significantly higher values than the control group (p < 0.05). In oxidative stress index (OSI) measurements, the bevacizumab group also showed significantly higher values compared to the control group (p < 0.05). In contrast, when the total antioxidant capacity (TAC) levels were compared, both the Trimetazidine 10(-)(4) and Trimetazidine 10(-)(5) groups demonstrated significantly higher values than the control group (p < 0.05). Regarding angiogenesis scoring, the bevacizumab group exhibited a significant anti-angiogenic effect compared to the control group. However, no statistically significant difference was observed between the Trimetazidine 10(-)(4) and Trimetazidine 10(-)(5) groups and the control group (p > 0.05). Conclusion Trimetazidine demonstrated significant antioxidant activity in an in vivo Chorioallantoic Membrane (CAM) model at both 10(-)(4) M and 10(-)(5) M concentrations. However, no positive or negative effects on angiogenesis were detected. We believe that the real-time observation of angiogenesis in our study provided significant value to our research.
