Article Potential Protective Effects of Boldine in Rat With an Experimental Myocardial Ischemia-Reperfusion Model(2025-03-25) Küçük, Ayşegül; Dursun, Alı Dogan; Arslan, Mustafa; Sezen, Şaban Cem; Yıldırım, Alperen Kutay; Özer, Abdullah; Yığman, ZeynepObjectives: Myocardial ischemia-reperfusion injury (MIRI) remains a major challenge in cardiovascular medicine due to its complex pathophysiology involving oxidative stress, inflammation, and cellular dysfunction. Boldine, a potent natural alkaloid with antioxidant and anti-inflammatory properties, has demonstrated protective effects in various pathological conditions. However, its potential cardioprotective effects in MIRI remain largely unexplored. This study aims to evaluate the protective effects of Boldine in a rat model of MIRI by assessing oxidative stress markers, histopathological changes, and inflammatory responses. Materials and Methods: Male Albino Wistar rats were randomly assigned to four groups: Control, Boldine, myocardial ischemia-reperfusion (MIR), and myocardial ischemia-reperfusion + Boldine (MIR+B). Myocardial ischemia was induced by ligating the left anterior descending coronary artery for 30 minutes, followed by 120 minutes of reperfusion. Boldine (50 mg/kg) was administered intraperitoneally at the onset of reperfusion. Cardiac tissue samples were collected for histopathological evaluation and biochemical analysis, including total antioxidant status (TAS), total oxidant status (TOS), and Oxidative Stress index (OSI). Results: Histopathological analysis revealed significant myocardial disorganization and inflammation in the MIR group compared to controls (p=0.05). Boldine treatment significantly reduced inflammation and myocardial disorganization in the MIR+B group (p<0.05), suggesting a protective effect. Biochemical analysis showed a marked decrease in TAS levels and an increase in TOS and OSI in the MIR group (p<0.001). However, Boldine administration significantly restored TAS levels and reduced TOS and OSI in the MIR+B group (p< 0.001), indicating attenuation of oxidative stress. Conclusion: Boldine exhibits significant cardioprotective effects in a rat model of MIRI by reducing oxidative stress, mitigating myocardial disorganization, and alleviating inflammation. These findings suggest that Boldine may serve as a therapeutic agent in ischemic heart disease. Further research is warranted to elucidate its precise mechanisms of action and potential clinical applications.Article Effectiveness of Boric Acid in Sepsis in Rats With Cecal Perforation(Springer Nature, 2025-11-28) Kurtipek, Ali Can; Dursun, Ali Dogan; Yigman, Zeynep; Ozdemir, Cagri; Kucuk, Aysegul; Gonullu, Ugur; Arslan, MustafaIntroduction and AimSepsis is a systemic inflammatory response that develops in the host against microorganisms, which results in end-organ damage. Boric acid (BA) has been shown to have immune modulatory effects in vitro and in animal studies. The aim of the study is to investigate the effects of high dose BA on lung and kidney tissues in rats with sepsis induced by the CLP method.Method28 rats were randomly divided into four groups: Group C (control group), Group BA, Group CLP (cecal ligation and puncture), and Group CLP + BA. Cecum was ligated below the ileocecal valve and punctured. BA was administered to the treatment groups at an intraperitoneal dose of 200 mg/kg, and at the end of 24 h, lung and kidney tissue samples were collected and evaluated for biochemical and histopathological parameters.ResultsHistopathologically, in kidney tissue, CLP + BA group showed significantly less peritubular capillary dilatation and brush border loss in the proximal tubule epithelium compared to the CLP group. In lung tissue, CLP + BA group had significantly less alveolar wall thickening compared to the CLP group. Biochemical analyses indicated that BA administration reduced oxidative stress in both renal and lung tissues.ConclusionWe found that intraperitoneal administration of high dose boric acid partially ameliorated the tissue damage in rats subjected to CLP induced sepsis. Further studies are needed regarding the dosage and application at different time points.Article Citation - Scopus: 1Enhanced Doxorubicin Cytotoxicity on Breast Cancer Spheroids by Aptamer Targeted Co-Delivery With Hyaluronidase(Wiley, 2025-08-06) Kavruk, Murat; Demirel, Dide Su; Bonyadi, Farzaneh; Guner, Buket Cakmak; Dursun, Ali Dogan; Vakifahmetoglu, Cekdar; Ozalp, Veli CengizBreast cancer is one of the most prevalent solid tumors in women and can be classified into subtypes based on molecular characteristics, such as hormone receptor status and HER2 expression. Aptamers, highly specific affinity molecules, are extensively studied for targeted drug delivery using nanocarriers to enhance anti-cancer efficacy. This study focused on HER2-responsive co-delivery of doxorubicin and hyaluronidase via aptamer-gated mesoporous silica nanoparticles to improve therapeutic outcomes in solid tumors. SK-BR-3 spheroids are employed as a model for resistant tumor environments in solid tumors. Previous research is shown that conjugating cytotoxic drugs with nanoparticles or cells enhances drug penetration into tumor spheroids. In this work, doxorubicin is loaded into mesoporous silica nanoparticles and capped with HER2-specific aptamers, while the particle surface is functionalized with hyaluronidase. This dual-functionalized nanocarrier system achieves an approximate to 8.5-fold increase in cytotoxicity compared to aptamer-targeted delivery lacking hyaluronidase. The enhanced effect is attributed to hyaluronidase-mediated loosening of the spheroid structure, facilitating nanoparticle penetration and localized release of doxorubicin at high concentrations on HER2-positive cells.Review Citation - WoS: 29Citation - Scopus: 31Real-Time Biosensing Bacteria and Virus With Quartz Crystal Microbalance: Recent Advances, Opportunities, and Challenges(Taylor & Francis inc, 2023-05-16) Bonyadi, Farzaneh; Kavruk, Murat; Ucak, Samet; Cetin, Barbaros; Bayramoglu, Gulay; Dursun, Ali D. D.; Ozalp, Veli C. C.Continuous monitoring of pathogens finds applications in environmental, medical, and food industry settings. Quartz crystal microbalance (QCM) is one of the promising methods for real-time detection of bacteria and viruses. QCM is a technology that utilizes piezoelectric principles to measure mass and is commonly used in detecting the mass of chemicals adhering to a surface. Due to its high sensitivity and rapid detection times, QCM biosensors have attracted considerable attention as a potential method for detecting infections early and tracking the course of diseases, making it a promising tool for global public health professionals in the fight against infectious diseases. This review first provides an overview of the QCM biosensing method, including its principle of operation, various recognition elements used in biosensor creation, and its limitations and then summarizes notable examples of QCM biosensors for pathogens, focusing on microfluidic magnetic separation techniques as a promising tool in the pretreatment of samples. The review explores the use of QCM sensors in detecting pathogens in various samples, such as food, wastewater, and biological samples. The review also discusses the use of magnetic nanoparticles for sample preparation in QCM biosensors and their integration into microfluidic devices for automated detection of pathogens and highlights the importance of accurate and sensitive detection methods for early diagnosis of infections and the need for point-of-care approaches to simplify and reduce the cost of operation.Article The Effect of Exercise Intensity on Ischemia/Reperfusion Injury and Myokine Profile in Diabetic Cardiomyopathy(Brill, 2024-09-11) Akat, F.; Tatar, Y.; Celik, H.; Ficicilar, H.; Dursun, A. D.; Bastug, M.Diabetes is a metabolic disorder characterised by hyperglycaemia. The diabetic heart becomes more susceptible to ischemic injury. Although exercise induces a cardioprotective phenotype, the determination of accurate protocol is crucial. We compared two different exercise intensities in the diabetes model and evaluated the role of myokines in exercise-induced cardioprotection. Male, adult, Wistar albino rats were used (n = 20 each). First, animals were divided into two groups: Non-Diabetic (ND), Diabetic (DM); then groups were further divided into subgroups: Sedentary (S), Training-1 (T1 =10 m/min, 00 inclination), and Training-2 (T2 = 20 m/min, 100 inclination). Diabetes was induced by streptozotocin (60 mg/kg; i.p.). Animals exercised on a treadmill 5 days/a week for 6 weeks. Then, hearts were attached to the Langendorff apparatus and baseline functional parameters were measured. After 30'/120'I/R protocol, infarct size was evaluated with tetrazolium chloride staining. Interleukin-6, FNDC5, and myonectin levels were measured both in the soleus and the left ventricle. We observed cardiac hypertrophy and impaired baseline LV function in diabetes. Infarct size was significantly larger in diabetics and only T1 decreased the infarct size whereas T2 further aggravated it. Moreover, post-ischemic recovery was worst in diabetic-T2 group. Irisin and myonectin levels were decreased in the soleus muscle of diabetic animals. T1 increased the myonectin levels in the left ventricle of non-diabetics, and this effect was blunted in diabetic-T1 animals. As a conclusion, light-intensity exercise is a better approach to prevent ischemic damage in diabetes besides moderate intensity may be hazardous in diabetic population.Article Farklı Dozlarda Uygulanan Apelin-13’ün Analjezik Minimum Etkin Dozu ve Böbrek Dokusu Üzerine Etkisi: Deneysel Çalışma(2024) Küçük, Ayşegül; Dursun, Alı Dogan; Arslan, Mustafa; Ozdemir, Cagri; Sezen, Şaban CemAmaç: Apelin ve APJ sinyal yolu; kalp, böbrek ve akciğer dâhil çeşitli dokularda eksprese edilmektedir. Bu yol kan bas ıncı, kardiyak kontraktilite, kalp h ızı, nosisepsiyon, apoptozis ve inflamasyon üzerinde çeşitli etkilere sahiptir. Mekanizması hâlen anlaşılamamasına rağmen Apelin-13’ün analjezik etkinli ği gösterilmi ştir. Gelecekte koruyucu ve tedavi edici bir ajan olarak kullan ılabilecek olması insan sağlığına önemli katk ılar sağlayacaktır. Bu sebeple ratlarda Apelin- 13’ün minimum analjezik etkin dozunu ve böbrek üzerine etkilerini araştırmayı amaçladık. Gereç ve Yöntemler: 30 adet Wistar Albino erkek rat, randomize olarak 5 gruba ayrıldı. Ratlar kontrol, Apelin-25, Apelin-50, Apelin-100 ve Apelin-200 gruplar ı olarak isimlendirildi. Apelin-13 intraperitoneal olarak 25, 50, 100 ve 200 μg/kg uyguland ı. Kontrol grubuna intraperitoneal olarak ayn ı hacimde salin uygulandı. Apelin uygulanmasından sonra 30. dk, 1. ve 2. saatlerde Hot Plate testi ile analjezik etkinlik de ğerlendirildi. 24 saat sonra histolojik ve biyokimyasal değerlendirmeler için tüm ratlardan kan ve doku örnekleri alındı. Bulgular: Hot Plate sonuçlarına bakıldığında 50 μg/kg ve üzeri Apelin-13’ün analjezik etkinlik gösterdiği tespit edildi. 25 μg/kg dozda analjezik etki görülmedi. 100 ve 200 μg/kg Apelin-13 uygulanan ratların böbrek dokusunda vasküler vakuolizasyon ve hipertrofi, Bowman aralık dilatasyonu ve tübüler hücre dökülmesi anlamlı olarak artmış bulundu. 200 μg/kg Apelin-13 uygulanan ratlarda doku oksidatif stres belirteçleri daha yüksekti. Sonuç: Literatürde Apelin-13’ün farklı dozlarda analjezik etkileri ile ilgili çalışmalara rastlamadık. 200 μg/kg Apelin-13 uygulamas ının böbrek dokusunu olumsuz etkiledi ğini bulduk. Apelin-13’ün minimum analjezik etkin dozunun intraperitoneal olarak uygulanan 50 μg/kg olduğunu tespit ettik.Article Citation - WoS: 29Citation - Scopus: 32Effects of Exercise Training on Anxiety in Diabetic Rats(Elsevier, 2019-12) Caliskan, Hasan; Akat, Firat; Tatar, Yakup; Zaloglu, Nezahet; Dursun, Ali Dogan; Bastug, Metin; Ficicilar, HakanDiabetes mellitus (DM) is a common health problem, which manifests itself with chronic hyperglycemia and impaired insulin action. The prevalence of anxiety disorders tends to be high in the diabetic population. Exercise has a well-known anxiolytic effect, also demonstrated on rodents, but the effect of exercise on the DM-induced anxiety is still unknown. Female, Wistar albino rats were randomly divided into four groups (n=8) (C; EX; DM; DM+EX). DM was induced by injection (i.p.; 50 mg/kg) of Streptozotocin (STZ). Rats exercised in moderate intensity on the treadmill (15m/min; 5 degrees; 30 min) for 5 weeks. Anxiety-like behavior (ALB) was evaluated by Open field test (OFT) and Elevated Plus Maze (EPM). According to OFT, central time and central entry have increased with in EX but not in DM+EX. There was no difference between C and DM. Central latency time didn't differ among groups. Unsupported rearing increased in both EX and DM+EX. There was no significant decrease in DM. Freezing time was significantly increased in the DM group. Exercise training reduced freezing time both in diabetic and non-diabetic animals. EPM results were similar. Time spent in open arm was increased significantly in exercise groups compared to their sedentary matches, and freezing time data were also parallel to OFT. Our study revealed that diabetes had shown an anxiogenic effect, which was not severe, and it only manifested itself on some behavioral parameters. Exercise training was reduced anxiety-like behavior both in diabetic and non-diabetic rats. However, because of the nature of exercise studies, it is hard to separate the anxiolytic effect of exercise from the alteration of locomotion.Article Citation - Scopus: 3Protective Effects of Metformin in Non-Diabetic Rats With Experimentally Induced Lower Extremity Ischemia-Reperfusion Injury(Turkish National Vascular and Endovascular Surgery Society, 2025-03-20) Küçük, Ayşegül; Dursun, Alı Dogan; Arslan, Mustafa; Sezen, Şaban Cem; Yıldırım, Alperen Kutay; Özer, Abdullah; Demirtas, HuseyinAim: Lower extremity ischemia-reperfusion (IR) injury can lead to substantial skeletal muscle damage and systemic complications, primarily driven by oxidative stress and inflammation. In addition to its well-known glucose-lowering effects, metformin possesses antioxidant and anti-inflammatory properties that may confer protection against tissue damage caused by IR. This study aims to evaluate the potential protective effects of metformin on skeletal muscle injury using a rat model of lower extremity IR.Material and Methods: A total of twenty-four male Wistar albino rats were randomly divided into four experimental groups: Control (C), Ischemia-Reperfusion (IR), IR with metformin at 4 mg/kg (IR+M4), and IR with metformin at 8 mg/kg (IR+M8). Ischemia was induced by clamping the infrarenal aorta for 45 minutes, followed by a reperfusion period of 120 minutes. In the treatment groups, metformin was administered intraperitoneally at the onset of ischemia. Gastrocnemius muscle tissues were harvested for subsequent histopathological and biochemical evaluations, including measurements of Total Antioxidant Status (TAS), Total Oxidant Status (TOS), and Oxidative Stress Index (OSI).Results: Histopathological analysis demonstrated a significant reduction in muscle atrophy, degeneration, leukocyte infiltration, and fiber fragmentation in the IR+M8 group compared to the IR group. Biochemical assessments showed that TAS levels were considerably elevated, whereas TOS and OSI levels were markedly reduced in the metformin-treated groups, with the most prominent effects observed at the higher dosage of 8 mg/kg.Conclusion: The findings indicate that metformin exerts a dose-dependent protective effect against skeletal muscle injury resulting from lower extremity ischemia-reperfusion in rats. These protective properties are likely due to metformin’s antioxidant and anti-inflammatory mechanisms, highlighting its potential therapeutic value in mitigating IR-induced tissue damage.Article Citation - WoS: 9Ozone Administration Reduces Myocardial Ischemia Reperfusion Injury in Streptozotocin-Induced Diabetes Mellitus Rat Model(Baycinar Medical Publishing, 2024-11-01) Gulcan, M.B.; Demirtas, H.; Ozer, A.; Yıgman, Z.; Dursun, A.D.; Arslan, M.; Oktar, G.L.Objective: This study aimed to investigate the effects of ozone therapy on myocardial ischemia/reperfusion injury in a diabetic rat model. Methods: The experimental study included 38 male Wistar Albino rats weighing between 200 and 250 g. The rats were randomly assigned to five groups. The sham group included six rats, while the other groups had eight rats each. The other groups were the diabetic ozone group, the diabetic group, the diabetic ischemia/reperfusion group (DIR), and the diabetic ischemia/reperfusion ozone group (DIRO). A total of 32 rats received 65 mg/kg streptozotocin, and a week after the administration, diabetes was confirmed by measuring blood sugar. The rats were fed ad libitum for 40 days to reveal macrovascular complications of diabetes. Malondialdehyde, catalase, superoxide dismutase, paraoxonase-1, total oxidative status, total antioxidant status, and oxidative stress index were assessed. A TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) assay was employed to assess apoptosis. Results: Histologic and biochemical assessments showed the benefits of ozone in myocardial ischemia/reperfusion injury in diabetic rats. The DIRO group was found to be superior to the DIR group. Conclusion: Ozone has cardioprotective effects in streptozotocin-induced diabetic rats through its antioxidant properties against oxidative stress. The study is unique in terms of ozone’s protective effects in diabetic rats against myocardial ischemia/reperfusion injury. However, further studies are needed to confirm our findings. © (2024), (Baycinar Medical Publishing).

For experimental IR, myocardial ischemia was performed by LAD ligation. Left thoracotomy was performed without ischemia in the Control group (Group C). Left thoracotomy was performed without myocardial ischemia to the rats in the HRSS group, and HRSS was given intraperitoneally (ip) at a rate of 10 ml/kg throughout the procedure. In the MIRHRSS group, a single dose of 10 ml/kg HRSS was administered 5 min before reperfusion. Histopathological and biochemical parameters were compared in myocardial tissue samples taken at the end of the reperfusion period.Results: When the groups were compared among themselves in terms of TOS and TAS levels, there was a significant difference between the groups (p = 0.006, p = 0.002). The severity of cardiomyocyte degeneration was significantly greater in MIR group than that in the control and HRSS groups (p = 0.002 and p = 0.001, respectively), as well as severity score of cardiomyocyte degeneration was higher in MIR-HRSS group compared with HRSS group (p = 0.035).Conclusion: Our study shows that HRSS is protective in IR injury, with the application of HRSS 5 min before reperfusion, interstitial edema severity, subendocardial haemorrhage are reduced, and oxidant status parameters are increased, while antioxidant status parameters are decreased. We believe that when it is supported by other studies, the protective effects of HRSS on IR damage will be shown in detail and its indications will be expanded.
