Article Citation - Scopus: 6Myrtus Communis L. Extract Ameliorates High Fat Diet Induced Kidney and Bladder Damage by Inhibiting Oxidative Stress and Inflammation(Istanbul University Press, 2022) Mustafaoglu, F.K.; Ertas, B.; Sen, A.; Akakin, D.; Sener, G.; Ercan, F.Objective: Obesity is associated with many diseases, including urinary system disorders such as chronic kidney disease and overactive bladder syndrome. Myrtus communis L. (MC) extract has been reported to have antioxidant and anti-inflammatory effects. The aim of this study was to investigate the protective effects of MC extract on high-fat diet (HFD)-induced kidney and bladder damage. Materials and Methods: Wistar albino male rats were divided into three experimental groups: control, HFD and HFD+MC. Experimental groups were fed a standard diet (control group) or HFD (HFD and HFD+MC groups) for 16 weeks. MC extract (100 mg/kg) was administered to the HFD+MC group orally during the last 4 weeks (5 days/week) of the experiment. High-density lipoprotein, total cholesterol, triglyceride and leptin levels were measured in blood serum. Tissue malondialdehyde (MDA), glutathione (GSH), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and myeloperoxidase (MPO) levels were evaluated biochemically. Kidney and bladder morphology, NADPH oxidase-2 (NOX-2) and nuclear factor-kappa B (NF-ҡB)-positive and apoptotic cells were evaluated histologically. Results: Lipid profiles altered and leptin levels increased in blood serum. MDA, 8-OHdG and MPO levels increased and GSH level decreased in kidney and bladder in the HFD group. Moreover, degenerated kidney and bladder morphology, increased NOX-2 and NF-ҡB-positive and apoptotic cells were observed in this group. All of these biochemical and histological parameters were ameliorated in the HFD+MC group. Conclusion: HFD-induced obesity causes kidney and bladder damage by oxidative and inflammatory processes. MC extract may reduce oxidative stress and inflammation and play a protective role in obesity-related kidney and bladder damage. © 2022 by the Author(s).Article The Correlation Between Vitamin D Levels and Thyroid Functions in Early Pregnancy(Yuzuncu Yil Universitesi Tip Fakultesi, 2025) Dinmez, Sinem; Özlem, Dülger; Oğul, Zeynep; Dülger, ÖzlemVitamin D deficiency (serum vitamin D <10 ng/ml) and thyroid dysfunctions are prevalent issues globally, particularly during pregnancy. Evidence suggests a potential link between thyroid function and vitamin D levels. This study aims to investigate the correlation between serum vitamin D levels and thyroid functions in wome n during the first trimester of pregnancy. The study was conducted retrospectively at a University Education and Research Hospital’s pregnancy clinic, covering data from August 2023 to March 2024. The sample group consisted of first -trimester pregnant women who attended routine pregnancy check-ups and had complete vitamin D levels and thyroid function tests (n=185). The sociodemographic data form and blood serum level assessment forms were used as data collection tools. The data were analyzed using descriptive statistics and correlation analysis. The average age of the pregnant women participating in our study was 27.6±4.9 years, and the Body Mass Index (BMI) was 25.4±4.8 (overweight). The mean number of pregnancies was 1.13±0.3, and the gestational week was 8.19±1.8. Of the participants, 35 had subclinical hypothyroidism, 37 had thyroiditis, and 113 had normal thyroid functions. The study identified 36 women with normal/adequate vitamin D levels (≥20 ng/ml), 113 with vitamin D insufficiency (10–20 ng/ml), and 36 with vitamin D deficiency (<10 ng/ml). The correlation analysis revealed no significant relationship between the thyroid function tests and vitamin D levels of the pregnant women. It was determined that vitamin D levels do not affect thyroid gland function in the first trimester.
