Öğe Anti-infective effect of Aquilaria malaccensis L. essential oil against Candida strains, the leading cause of yeast infectious(2025) Unver, Tuba; ERENLER, SEBNEM; KIRAN, TUGBA RAIKAAquilaria malaccensis L., known as Agarwood, is widely found in India, Malaysia, Bhutan, and Indonesia. It is a pleasantly scented plant used in the production of resin. It is an interesting material in the field of health due to its resin and essential oil, which exhibit antimicrobial properties. This study aimed to evaluate the antifungal properties of A. malaccensis L. essential oil and determine its minimum inhibitory concentrations (MIC) against the Candida species tested. The inhibitory effect of A. malaccensis L. essential oil was tested on five Candida species. The broth microdilution method was used to determine the MIC values against the tested microorganisms, and the viability of microorganisms exposed to the plant essential oil was assessed using resazurin sodium salt. According to the results, the MIC of the plant essential oil against Candida tropicalis, Candida krusei and Candida albicans is 62.50 µL/mL. While the MIC against Candida glabrata is 31.25 µL/mL, the MIC against Candida parapsilosis is 7.81 µL/mL. These results show the potential of A. malaccensis L. as an anti-candidal agent. The continuation of this study revealed the need for optimizing and implementing more comprehensive antimicrobial tests.Öğe Assessing lipoxin-mediated inflammatory responses in the second trimester of pregnancy among women with obesity: A comprehensive analysis(2023) Otlu, Önder; MELEKOGLU, RAUF; KIRAN, TUGBA RAIKA; İnceoğlu, Feyza; ERENLER, SEBNEMObjective: This study aimed to explore the relationship between maternal plasma lipoxin A4 (LXA4) levels during the second trimester of pregnancy and certain proinflammatory molecules, such as interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-?), as well as the antiangiogenic factor vascular endothelial growth factor receptor 1 (VEGFR-1), in conjunction with obesity among pregnant women. Materials and Methods: A total of 30 pregnant women with obesity were compared with 30 pregnant women of normal weight, matched for both age and gestational week. Plasma samples were collected from all participants between the 18th and 28th weeks of pregnancy. The levels of LXA4, VEGFR-1, IL-6, and TNF-? were quantified using enzyme-linked immunosorbent assay. Results: Plasma levels of LXA4 were notably lower in pregnant women with obesity, whereas levels of TNF-? and VEGFR1 were significantly higher (p=0.041, p<0.001, and p<0.001, respectively). There was no significant difference in IL-6 levels between groups (p=0.072). The binary logistic regression model revealed significant associations between obesity and the examined inflammatory mediators. Specifically, the results demonstrated that higher levels of LXA4 were linked to a reduced obesity risk, with each unit increase corresponding to a 0.926-fold decrease in the likelihood of obesity. Conversely, elevated levels of TNF-? and VEGFR1 were associated with an increased risk of obesity. Conclusion: The study concluded that increased body mass index during pregnancy affects the levels of plasma lipoxin, cytokines, and angiogenesis-related factors. Although the exact mechanisms remain unclear, the observed changes suggest a disruption in the metabolic systems of women with obesity, which may influence physiological changes during pregnancy and lead to obesity-related pathological conditions.Öğe Could ELABELA be a Protective Biomarker in Patients with Abnormal Uterine Bleeding?(2024) KIRAN, TUGBA RAIKA; Doğan, Ümran Karabulut; Otlu, Önder; yildirim, engin; Erdem, Mehmet; İnceoğlu, FeyzaAim: Abnormal uterine bleeding (AUB) is a health problem characterized by various symptoms such as heavy and prolonged menstrual bleeding, affecting approximately 30% of female patients both physiologically and psychologically. The objective of this study was to assess serum Elabela (ELA) concentrations in women aged 18 and above diagnosed with functional AUB, and to compare these concentrations with those of healthy women. Material and Method: This prospective case-control study was performed from August 18, 2022 to December 30, 2022. This was a cross-sectional study including 50 women who applied to the gynecology service of Malatya Turgut Özal Training and Research Hospital with complaints of AUB and 50 women without AUB who underwent gynecological examination. The presence of AUB in patients was determined based on clinical examination conducted by a gynecologist and medical records. Demographic and clinical characteristics were recorded. Serum ELA levels were determined by commercial ELISA kit. Results: Serum ELA levels was significantly lower in patients with AUB (581.54±272.25 pg/mL) compared to the healthy group (744.55±300.31 pg/mL, p=0.005). In this study, ELA in patients with AUB showed 98% sensitivity and 80% specificity with a cut off value of 411.41 pg/mL (area under the curve [AUC], 68.1%; p=0.002). Conclusion: Serum ELA levels in patients with AUB were significantly lower than in healthy women. These results show that ELA is a good predictor of the pathophysiological process of AUB.Öğe CRP and LDH Levels Can Be Used for Support the COVID-19 Diagnose in Intensive Care Unit Patients(2023) Otlu, Önder; kurt, zeynep; İnceoğlu, Feyza; Karaman, Ülkü; KIRAN, TUGBA RAIKAAim: The coronavirus disease (COVID-19) has been a public health problem that causes severe acute respiratory syndrome affected all over the word since 2019. The most commonly used parameters as inflammatory response in the clinic are leukocytes, neutrophils, erythrocyte amount and serum C-reactive protein (CRP). In recent years, it has been reported that serum PCT (procalcitonin) level may be useful in the diagnosis of bacterial and viral infections. The aim of our study is to compare blood parameters that may play a supportive role to diagnose of COVID-19 in healthy control and critically COVID-19 patient groups. Material and Methods: This retrospective research was carried out in Malatya Turgut Ozal University Training and Research Hospital, Malatya, Türkiye. Total 88 critically ill patients and 90 healthy people accepted to the study and electronic medical records of patients and control group has been collected from hospital information system (HIS). COVID-19 diagnose has been confirmed by real-time polymerase chain reaction (RT-PCR) results. Results: No statistically significant difference was found between the patient and control groups according to gender in the participants included in the study. A statistically significant increase was observed in CRP, LDH, PCT, D-dimer, urea, sediment, lympocyte and neutrophil levels in COVID-19 patients. According to logistic regression analysis CRP, LDH and sediment values were found to be statistically effective in estimating the COVID-19 infection. These results also supported by ROC analysis, CRP, neutrophil, LDH, PCT and D-dimer results were determined to be distinguishing parameters for COVID-19 patients. Conclusion: We found that CRP, PCT and LDH levels higher in the COVID-19 patients and these parameters can be used to diagnose and estimate the prognose of COVID-19 infection in intensive care patients.Öğe Does the high sulfur content in apricots affect oxidative stress? Running title: Effect of sulfur amount on oxidative stress(2022) Otlu, Önder; KIRAN, TUGBA RAIKA; Gül, Mehmet; Önal, Yunus; ÇOLAK, Cemil; karabulut, aysun bayApricots are one of the most important fruits that can be produced worldwide. Most of the importer countries are sensitive about sulfur which is used in the protection of dried apricots. The objective of this study was to compare the effects of feeding with high and low sulfur content apricots on oxidative stress parameters of the liver. In total, 42 Wistar albino rats were fed for 12 weeks with the use of dried apricots containing different amounts of sulfur and sun-dried apricots. There was no significant difference in IL-1?, 8-OHdG and TOS levels between the control group and the group fed with sun dried apricots. There was no statistically significant difference between the groups fed with low and high sulfur-containing apricots.Non-necrotic changes were observed in 3000 ppm and 4000ppm groups in microscopic examination. No significant effect of feeding with sulfur treated apricots was found in the liver tissues of rats.Öğe Exploring Irisin and Nesfatin-1 in second trimester amniotic fluid: a comparative study of obese and normal weight pregnant women(2024) ERENLER, SEBNEM; MELEKOGLU, RAUF; KIRAN, TUGBA RAIKA; İnceoğlu, FeyzaObjective: Obesity is characterized by dysregulated adipokine production patterns, leading to low-grade inflammation. Irisin has been identified as a potential target for the treatment of diabetes and obesity. Nesfatin-1, another adipokine, plays a significant role in various metabolic processes, including glucose homeostasis. This study investigated the levels of the new generation adipokines, irisin and nesfatin-1, in the amniotic fluid during the second trimester of normal and obese pregnancies. Methods: Amniotic fluid samples were collected following established protocols. The first 2 mL portion of fluid obtained during amniocentesis was retained aAfter centrifugation at 1500 g for 10 minutes, the cell-free amniotic fluid was transferred to Eppendorf tubes and quantitative measurements of irisin and nesfatin-1 levels were performed using the Enzyme-Linked Immuno Sorbent Assay (ELISA) method. Results: Our results demonstrate, for the first time in the literature, the presence of irisin and nesfatin-1 in amniotic fluid. Additionally, we found that the levels of these adipokines were significantly lower in obese pregnant women compared to the control group (both p<0.05). Conclusion: Our results demonstrate, for the first time in the literature, the presence of irisin and nesfatin-1 in amniotic fluid. Additionally, we found that the levels of these adipokines were significantly lower in obese pregnant women compared to the control group (both p<0.05).Öğe Iron Deficiency may be a Risk Factor for Inguinal Hernia Development in Children(2023) Harma, Birsen; KIRAN, TUGBA RAIKA; İnceoğlu, FeyzaObjectives: This case control study aimed to investigate whether the routine hemogram and biochemical parameters of pediatric patients who have undergone surgery for inguinal hernia are associated with the etiopathogenesis of the disease. Methods: Eighty cases of inguinal hernia surgery performed between January 2019 and November 2022 were included in the study. A control group was also established using hospital records, consisting of eighty pediatric patients without any known his- tory of hematological or metabolic disease or use of regular medication. Statistical analysis was conducted to compare the total hemoglobin (Hgb), hematocrit (Htc), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), erythrocyte distribution width (RDW) and thrombocyte (PLT) values in both groups. Results: The age range of the pediatric patients was 1-14 years. Of the eighty children, 47 (58.8%) were male and 33 (41.3%) were female, with a mean age of 5.79±3.26. The values of Hgb, Htc, MCH, MCHC, and MCV in the inguinal hernia patients were found to be statistically significantly lower than those in the control group (p<0.05). Additionally, the patient RDW values were found to be statistically significantly higher than those in the control group (p<0.05). Conclusion: Compared to the control group, the observed decrease in MCH, MCHC, MCV, Hgb, HTC values, as well as the increase in RDW in patient group, suggests a predisposing effect of iron deficiency. These specific changes suggested that iron deficiency may lead structural changes in the collagen construction and may contribute the etiopathogenesis of childhood inguinal hernia.Öğe Oxidative Stress and Anti-Carbonic Anhydrase Antibody Levels in Early Preeclampsia: A Clinical Investigation(2024) ERENLER, SEBNEM; MELEKOGLU, RAUF; KIRAN, TUGBA RAIKA; İnceoğlu, FeyzaAim: Preeclampsia (PE) is a dangerous condition that affects 3–5% of pregnancies and has a substantial risk of death and morbidity for both mothers and newborns. The processes behind the etiology of PE are not entirely known, despite the fact that it is the primary cause of illness and death among mothers globally. In order to further understand the correlations between these parameters, this study will look at the levels and presence of anti-carbonicanhydrase (CA) I and II antibodies, total oxidant capacity (TOC), total antioxidant capacity (T-AOC), and malondialdehyde (MDA) in early PE. Material and Method: The research analyzed 30 pregnant women with early PE and 30 normal pregnant women as the control group. Serum levels of anti-CAI (pg/mL), anti-CAII (ng/mL), MDA (nmol/mL), TOS (U/mL), T-AOC (U/mL) were measured and compared between the two groups. Results: Significant variations were noted in the amount of anti-CA I, anti-CA II, MDA, TOS, and T-AOC (both p<0.05) between the control group and the early PE group. More specifically, oxidative stress indicators were changed and increased levels of anti-CA I and anti-CA II were seen in the early PE group in comparison with the control group. Conclusion: The findings show that elevated amounts of anti-CAI and anti-CAII antibodies may serve as predictive markers for early PE. The significant differences in oxidative stress parameters further support the oxidative stress involvement in the pathogenesis of early PE. However, more extensive Research is required to validate these results and clarify the mechanisms underlying PE.Öğe Some biochemical tips in the etiopathogenesis of Pectus Excavatum(2023) Harma, Birsen; KIRAN, TUGBA RAIKA; İnceoğlu, FeyzaPectus excavatum (PE) is the most common deformity among anterior chest wall abnormalities. Although many theories on the pathogenesis of PE have been described, the uncertainty is still going on whether it is a result of developmental, biochemical, or biomechanical reasons or their combination. The aim of this study was to evaluate the biochemical parameters that may cause or be associated with the development of PE between children with PE and their healthy peers. A total of 33 patients' medical records were retrospectively analyzed who followed up because of pectus excavatum between 2019 and 2021. A control group was formed from 32 healthy children from the hospital records with similar age and gender profiles as the patient group. The data from both groups were collected and statistically analyzed in terms of gender, age, and laboratory tests, including hemogram, Vit B12, Parathormone (PTH), Vit.D, Alkaline phosphatase (ALP), and serum Calcium (Ca) and Phosphor (P) levels. Compared to the control group, statistically, significantly higher serum ALP, P, and PTH levels with low Vit.B12 levels were detected. The significant difference in the levels of ALP, PTH, P, and Vit B12, which have an important place in the construction and development of osteochondral structures, may impair the remodeling capacity of the costosternal structure with the contribution of thoracic biomechanics. When PE deformity is noticed, if appropriate medical treatment such as vitamin and mineral supplements and diet regulation is applied to children in the follow-up process, the process can be slowed down, and the deformity can be alleviated.
