Article Citation - WoS: 26Citation - Scopus: 281-(2-Hydroxyethyl)-2-imidazolidinone as corrosion inhibitor of mild steel in 0.5 M HCl solution: thermodynamic, electrochemical and theoretical studies(Journal of Adhesion Science and Technology, 2019) Keleşoğlu, Ayşen; Yıldız, Reşit; Dehri, İlyasThe inhibition effect of 1-(2-Hydroxyethyl)-2-imidazolidinone (2-HEI) on mild steel (MS) corrosion in 0.5M HCl solution was investigated at different inhibitor concentration and temperature by electrochemical experiments, such as linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and quantum chemical calculations. The inhibitor adsorption process on mild steel in 0.5M HCl system was studied at different temperatures (20 C–50 C). Furthermore, the surface morphology of MS was also investigated with SEM in the absence and the presence of inhibitor. The adsorption of 1-(2-Hydroxyethyl)-2-imidazolidinone on MS surface is an exothermic process and this process obeys the Langmuir adsorption isotherm. The Quantum chemical findings are good agreed with the empirical data.Article Citation - WoS: 6Citation - Scopus: 9Adaptions in subsistence strategy to environment changes across the Younger Dryas-Early Holocene boundary at Kortiktepe, Southeastern Turkey(Sage Journals, 2022) Emra, Stephanie; Benz, Marion; Sıddıq, Abu Bakar; Özkaya, VecihiThe site of Körtiktepe in southeastern Turkey is one of few sites in the Upper Mesopotamia basin that attests continuous, permanent occupation across the boundary from end of the colder, drier Younger Dryas (YD) into the comparatively wetter and warmer Early Holocene (EH). This allows for the study of the degree of environmental change experienced on a local level over this boundary as well as for the study of the adaptations that the occupants of the site undertook in response to these changes. The mammal assemblage of Körtiktepe remains relatively stable across the YD – EH transition with the main contributors to diet being mouflon (Ovis orientalis) and red deer (Cervus elaphus) in approximately the same quantities, although the contribution of aurochs (Bos primigenius) increases in the EH. The most significant changes can be seen in the shift in avifauna remains, with a sharp increase of waterbirds during the EH. It is proposed that these shifts reflect changes in the local environment with an increase in woodland cover as well as expansion of local waterways, which is generally consistent with previously published archaeobotanical studies. In terms of species exploited, mortality profiles as well as size distribution of mammals, a great deal of continuity is observed. This suggests that over this particular period the local impact of the beginning of the Early Holocene was not overly dramatic, allowing for cultural continuity of previously established subsistence strategies.Article Citation - WoS: 59Citation - Scopus: 63Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation(SPRINGER HEIDELBERG, 2019) Yildiz, Resit2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by E-pzc measurements.Article Citation - WoS: 18Citation - Scopus: 16Alpha-lipoic acid may ameliorate testicular damage by targeting dox-induced altered antioxidant parameters, mitofusin-2 and apoptotic gene expression(Andrologia, 2021) Güzel, Elif Erdem; Kaya Tektemur, Nalan; Tektemur, AhmetIn the study, the ameliorating effects of alfa lipoic acid (ALA) against doxorubicin-induced testicular apoptosis, oxidative stress and disrupted mitochondrial fusion were investigated in male rats. Rats were divided into four groups as control, doxorubicin (DOX), DOX + ALA and ALA. A single dose of 15 mg/kg DOX was administered i.p to the DOX and DOX + ALA groups. 50 mg/kg ALA was given to the DOX + ALA and ALA groups by oral gavage every other day. After 28 days, rat testes and serum samples were collected and analysed. Administration of DOX alone caused a decrease in body and relative testicular weights, seminiferous tubule diameter and germinal epithelium thickness, Johnsen's score and serum testosterone levels. DOX treatment led to severe testicular damage such as tubular degeneration, and atrophic tubules. Also, the activities of superoxide dismutase and glutathione peroxidase were reduced, while the level of malondialdehyde was increased in the testis. The mRNA levels of apoptotic-related genes (CASP3, TP53, BAX, BCL2) and apoptotic index were increased, while mitofusin-2 decreased. DOX caused an increase in CASP3 and a decrease in mitofusin-2 immunoreactivities. Treatment with ALA markedly improved all of DOX-induced biochemical, histochemical and molecular alterations in rat testis. Consequently, ALA has a therapeutic role in ameliorating DOX-induced testicular damage in rats.Article Citation - WoS: 10Citation - Scopus: 14The antioxidant and anti-apoptotic potential of Pleurotus eryngii extract and its chitosan-loaded nanoparticles against doxorubicin-induced testicular toxicity in male rats(Wiley, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Tektemur, Ahmet; Acay, Hilal; Yıldırım, AyferThis study was conducted to evaluate the protective role of Pleurotus eryngii extract (PE) and Pleurotus eryngii extract-loaded chitosan nanoparticles (PE-CSNP) against doxorubicin (DOX)-induced testicular toxicity in rats. Male rats were divided into six groups: control (DMSO/ethanol), PE (200 mg/kg PE), PE-CSNP (30 mg/kg PECSNP), DOX (10 mg/kg DOX, a single dose, i.p), DOX+PE (10 mg/kg DOX+200 mg/ kg PE) and DOX+PE-CSNP (10 mg/kg DOX+30 mg/kg PE-CSNP). PE and PE-CSNP were administered by oral gavage every other day for 21 days. DOX-treated rats showed histopathological impairment compared with the control group. There was an increase in the apoptotic index, caspase 3 (CASP3), BCL2-associated X apoptosis regulator (BAX), dynamin-related protein 1 (DRP1) expression and total oxidative status (TOS) in the DOX group, while mitofusin-2 (MFN2), total antioxidative status (TAS) and serum testosterone levels of the DOX group reduced when compared with the other groups. PE and PE-CSNP treatments provided significant protection against DOX-induced oxidative stress by reducing TOS levels and increasing TAS levels. CASP3, BAX, apoptotic index and DRP1-MFN2 expressions were restored by PE and PE-CSNP. However, the PE-CSNP showed higher antioxidant and anti-apoptotic efficacy compared with PE. Thus, our results provide evidence that CSNP and PE could synergistically have a potent antioxidant and anti-apoptotic therapy against DOX-induced testicular damage in male rats.Article Citation - Scopus: 1Application of muntz-legendre polynomials for solving complex differential equations(Sigma Journal of Engineering and Natural Sciences, 2021) Düşünceli, Faruk; Çelik, ErcanThis paper has obtained the numerical solutions of complex differential equations using the Müntz-Legendre Polynomials. The technique was performed on test problem. Then, different technical error analyses were applied to the test problem. Finally, when exact solutions and numerical solutions were compared with tables and graphs, it was realized that our method is practical and reliable.Article Citation - WoS: 8Citation - Scopus: 6The association of allergic rhinitis severity with neutrophil-lymphocyte and platelet-lymphocyte ratio in children(Northern Clinics of İstanbul, 2022) Cansever, Murat; Sarı, NeslihanObjective: The aim of the study was to investigate the relationship between the severity of allergic rhinitis (AR) and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in pediatric patients. Methods: This study is a retrospective, cross-sectional, and observational study including 200 AR patients and 160 healthy controls. Of the patients, 39% were boys with a mean age of 10.5 years. The study included children with persistent and intermittent AR. Of the controls, 50.6% were boys with a mean age of 10.3 years. We compared NLR and PLR from blood test between study and control groups. They were also compared according to AR severity within the patient group. Results: The NLR was 1.64±1.29 in the study group whereas 1.18±0.31 in the control group. The PLR was 102.72±31.20 in the study group whereas 79.36±11.72 in the control group. When NLR and PLR were compared between groups, we found statistically significant differences in both NLR and PLR (p=0.003, p=0.001, respectively). We found a statistically significant difference when comparing both NLR and PLR in patients with intermittent and persistent AR. These rates increased with disease severity (p=0.000, p=0.000, respectively). Conclusion: Both NLR and PLR are useful markers for the diagnosis and severity of AR. Clinicians can use these markers to assess disease severity in pediatric patients at the beginning of the diagnostic process.Article Citation - WoS: 10Citation - Scopus: 10Awareness of risk factors and warning signs of stroke among caregivers of patient with and not with stroke: Results from questionnaire(Journal of Pakistan Medical Association, 2019) Usta Yeşilbalkan, Öznur; Karadakovan, Ayfer; Vural Doğru, Birgül; Akman, Perihan; Özel, Ebru; Bozkurt, YücelObjective: To assess the awareness/knowledge of stroke risk factors and warning signs among caregivers of patients with or without stroke. Methods: The cross-sectional, descriptive and comparative study was conducted in the neurology clinic and polyclinic of a university hospital in Izmir, Turkey, from March to July 2014, and comprised primary caregivers of patients with stroke in group 1 and those of patients with no stroke in group 2. The subjects were screened and data was collected using the Participant Information Form and the Questionnaire Form About Stroke. Warning signs and symptoms of stroke were compared between the two sets of caregivers. SPSS 17was used for data analysis. Results: Of the 203 respondents, 105(52%) were in group 1 and 98(48%) in group 2. Group 1 had better awareness than group 2 (p<0.05). In group 1, weakness was the most commonly recognised warning sign 101(96.2%), whereas dyspnoea 41(39%), was the least commonly identified. There was no relationship of stroke knowledge with educational level and age (p>0.05 each). Conclusions: Caregivers had a moderate knowledge of some of the warning signs and risk factors about stroke.Article Citation - WoS: 7Citation - Scopus: 7Biochemical components, enzyme inhibitory, antioxidant and antimicrobial activities in endemic plant Scilla mesopotamica speta(Wiley, 2021) Aktepe, Necmettin; Keskin, Cumali; Baran, Ayşe; Atalar, Mehmet Nuri; Baran, Mehmet Fırat; Akmeşe, ŞükrüIn this study, in vitro antioxidant, antimicrobial, anticholinesterase and phenolic profile of different solvent extracts of Scilla mesopotamica speta were determined in detail. In vitro antioxidant activities and total phenolic and flavonoid contents of plant extracts obtained with different solvents were tested in terms of 2.2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activities. The highest total phenolic and total flavonoid contents were determined in the ethyl acetate extract (62.24 mu g GAE/mg) and chloroform extract (87.72 mu g QE/mg) respectively. The highest DPPH radical scavenging activity was detected in ethyl acetate extracts. Antimicrobial and antifungal activities were investigated by MIC method. The inhibitory activities of the extracts on the acetyl cholinesterase enzyme were investigated. Liquid chromatography (LC) tandem mass spectrometry LC-MS/MS was used to determine the phenolic component content of extracts. Thirty-one different components were identified in the analyses and their amounts were measured. Practical applications Scilla mesopotamica speta is an endemic and medicinal plant. It was determined that the extracts of this plant had a very rich content in terms of phenolic compounds, especially caffeic and ferulic acids. However, this plant was remarkable for its antioxidant, anticholinesterase, and antimicrobial activities. Considering the strong antioxidant, antimicrobial, and enzyme inhibition activities of the Scilla mesopotamica speta it can be suggested as a source of anticancer, antimicrobial, and antiviral drugs.Article Citation - WoS: 11Citation - Scopus: 11Biosensors for the Detection of Pathogenic Bacteria: Current Status and Future Perspectives(Future Medicine Ltd, 2024) Dicle, Yalcin; Karamese, MuratPathogenic microorganisms pose significant threats to human health, food safety and environmental integrity. Rapid and accurate detection of these pathogens is essential to mitigate their impact. Fast, sensitive detection methods such as biosensors also play a critical role in preventing outbreaks and controlling their spread. In recent years, biosensors have emerged as a revolutionary technology for pathogen detection. This review aims to present the current developments in biosensor technology, investigate the methods by which these developments are used in the detection of pathogenic bacteria and highlight future perspectives on the subject. Microorganisms that cause disease are important not only to human health but also to food safety and environmental health. Therefore, it is important to detect these microorganisms quickly, easily, at a low cost and with accuracy. Biosensors have all of these features and offer a unique way to detect microorganisms. They are already being used in similar fields and are becoming increasingly portable and ergonomic devices. This paper looks at the uses of biosensors in detecting disease-causing bacteria and how their use will develop with greater technology. Outbreaks caused by pathogenic bacteria are a global concern, not only for human health but also for food safety and bioterrorism. This paper provides an overview of how biosensors can be used in the quick, easy and low-cost detection of pathogenic bacteria.Article Citation - WoS: 1Citation - Scopus: 1Black box in overactive bladder: Central sensitization and its relationship with urinary symptom severity and quality of life(Wiley, 2024) Toprak Şelenay, Ceyda; Altay, Hafize; Bülbül, Saliha Beste; Oskay, Kemal; Celenay, Seyda T.Aim: To examine central sensitization (CS), and to investigate the relationship between CS, and urinary symptom severity, and quality of life (QoL) in women with overactive bladder (OAB). Materials and methods: A total of 144 women with OAB included the study. CS with the Central Sensitization Inventory (CSI), urinary symptom with the Overactive Bladder Questionnaire-Version 8 (OAB-V8), bladder diary and Patients' Perception of Intensity of Urgency Scale (PPIUS) and QoL with the King's Health Questionnaire (KHQ) were assessed. Results: It was found that 47.9% (n = 69) of women with OAB had CS. It was observed that the CSI score was related to the OAB-V8 score (ρ = 0.327; p < 0.001) and the average number of voids/day (ρ = 0.291; p < 0.001). Additionally, urgency severity was higher in women with OAB with CS than in women with OAB without CS (p = 0.006). There was a relationship between the CSI score and KHQ-incontinence impact (ρ = 0.250; p = 0.012), KHQ-personal relationship (ρ = 0.253; p = 0.002), KHQ-sleep/energy (ρ = 0.180; p = 0.031), KHQ-emotional state (ρ = 0.310; p < 0.001) and KHQ-severity measurement scores (ρ = 0.391; p < 0.001). Conclusion: In this study, it was observed that the majority of women with OAB had CS. It was found that more severe symptoms of CS were associated with worse urinary symptom severity and QoL in these patients. It may be beneficial to evaluate CS in the management of OAB and to consider CS when determining treatment strategies.Article Citation - WoS: 10Citation - Scopus: 12Carbamazepine-induced renal toxicity may be associated with oxidative stress and apoptosis in male rat(Taylor & Francis Online, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Tektemur, Ahmet; Etem Önalan, EbruCarbamazepine (CBZ) is the antiepileptic drug used in epilepsy and some psychiatric disorders. Besides its widely used, many adverse effects have been reported including hematotoxicity, hepatotoxicity, endocrine disorders, and testicular damages due to oxidative stress. However, the role of CBZ on renal toxicity is not fully known. In this study, we attempted to explain the connected mechanisms by focusing on the metabolism of CBZ-induced renal toxicity in rats. Twenty male Wistar-Albino rats were randomized into 2 groups (n = 10); control (1 mL/day distilled water, orally) and CBZ (25 mg/kg/day CBZ, orally) groups. After 60 days, TAS (total oxidant status) and TOS (total oxidant status) levels, histopathological features, some genes involved in apoptosis, 8-hydroxy-2-deoxyguanosine (8-OHdG) activity, and apoptotic cells were assessed of kidney tissue. The oxidative stress index (OSI) was measured from TAS and TOS levels. TOS levels and OSI significantly increased, while TAS levels decreased in the CBZ group relative to the control group. Histopathological observations, Caspase-3 (Casp3), Poly [ADP-ribose] polymerase-1 (PARP-1), 8-OHdG immunoreactivities, and apoptotic cells markedly raised in the CBZ group compared with the control group. Also, mRNA expression of Cytochrome c (Cytc) and CASP3 significantly increased in the CBZ group compared to the control group. In conclusion, long-term use of CBZ may promote renal damage in rats by inducing oxidative stress and apoptosis.Article Citation - WoS: 4Citation - Scopus: 6The combination of N-acetylcysteine and cyclosporin A reduces acetaminophen-induced hepatotoxicity in mice(Ultrastructural Pathology, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Gül, Mehmet; Tektemur; Özcan Yıldırım, Sena; Kavak Balgetir, Merve; Ozan Kocamüftüoğlu, Gonca; Yalçın, Tuba; Ozan, & İbrahim EnverAcetaminophen (APAP)-induced hepatotoxicity is the most common cause of acute liver failure in worldwide. N-acetyl cysteine (NAC) is used as the APAP antidote. Cyclosporin A (CsA) is suppressed mitochondrial damage by binding cyclophilin, a mitochondrial pore transport component. The study aimed to evaluate the effects of NAC, CsA, and NAC+CsA treatments on APAP-induced hepatotoxicity in mice. Mice were randomly divided into five groups (n = 6). 400 mg/kg/ip/single dose APAP, 1200 mg/kg/i.p/single dose NAC and 50 mg/kg/i.p/single dose CsA were performed. Light and electron microscopic alterations were investigated in liver samples. Levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and liver glutathione (GSH) were analyzed. 3-nitrotyrosine and cytochrome c immunoreactivities were evaluated in liver tissue. Here, we found that APAP leads to histopathological and ultrastructural changes in mice liver. Also, APAP increased cytochrome c and 3-nitrotyrosine immunopositive staining. Besides, a significant decrease in liver GSH and an increase in serum AST and ALT levels were detected in the APAP group. Interestingly, NAC+CsA treatment improved histological alterations, cytochrome c, and 3-nitrotyrosine immunoreactivities and liver GSH, serum AST/ALT levels caused by APAP. We suggest that the combination of NAC and CsA reduces acetaminophen-induced hepatotoxicity in mice.Article Community Displacement Challenges in Educational Tourism(Routledge Journals, Taylor & Francis Ltd, 2025) Cizreliogullari, Mehmet NecatiThis study investigates issues relating to community displacement of the indigenous residents of Famagusta resulting in an increased rate of relocation to the suburbs due to the sudden growth of educational tourism; thus, the main objective of the current study is to obtain perspectives of learners on primary motives. An in-depth interview of 28 Cypriots in Famagusta, through purposive sampling was used to gather data for the current research. Findings reveal that the increase in educational tourism in Famagusta caused the indigenous Cypriots to move into suburban neighbourhoods. Factors including urbanization issues, social issues, economic issues, cultural issues, and environmental issues were revealed to be the most challenging issues resulting in community displacement.Article Citation - WoS: 1Citation - Scopus: 2Comparative Study of Lipid and Fatty Acid Profile in Liver Tissues of Male and Female Silurus triostegus During the Catching Seasons(2021) Kaçar, Semra; Başhan, MehmetIn this study, seasonal variations of total fatty acid (FA), phospholipid (PL) and triacylglycerol (TAG) compositions in liver tissues of catfish (Silurus triostegus) were investigated. Samples of S. triostegus were obtained from Atatürk Dam Lake, Turkey, in two month periods during one year as from May. The major components were palmitic acid (16:0), stearic acid (18:0), oleic acid (18:1n-9), palmi toleic acid (16:1n-7), docosahexaenoic acid (DHA, 22:6n-3) and arachidonic acid (AA, 20:4n-6) in total lipid, 16:0, 18:0, 18:1n-9, eicosapentaenoic acid (EPA, 20:5n-3), DHA and AA in PL, 16:0, 16:1n7, 18:1n-9, linoleic acid (LA, 18:2n-6), AA, EPA, DHA and docosapentaenoic acid (22:5n-3) in TAG extracted from the liver of S. triostegus in all seasons. N-3/n-6 ratio was found 2.00-2.61 in females, 1.15-2.75 in males in total lipid. The highest lipid content was found in May (2.39%) in the females. In the males, the highest level was found in September (2.91%). In TAG fraction, the component with the lowest ratio in both sexes’ TAG is PUFA. In PL fraction, SFA, MUFA, and PUFA percentages were found at similar rates in both sexes in all months.Article Citation - WoS: 3Citation - Scopus: 4Determination of Chemical Composition and Antioxidant, Cytotoxic, Antimicrobial, and Enzyme Inhibition Activities of Rumex Acetosella L. Plant Extract(Springer int Publ AG, 2024) Kandemir, Sevgi Irtegun; Aktepe, Necmettin; Baran, Ayse; Baran, Mehmet Firat; Atalar, Mehmet Nuri; Keskin, Cumali; Khalilov, Rovshan; Irtegün Kandemir, SevgiPurpose The phenolic composition, antioxidant, antimicrobial activity, enzyme inhibition activity, and cytotoxic activity potentials of the plant Rumex acetosella L. (R. acetosella) were examined in this study. Materials and Methods: The chemical composition of R. acetosella methanol extract was identified by the LC-MS/MS method. The antioxidant activity was tested using beta-carotene/linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC reducing power, and metal chelating activity methods. The cytotoxic activity was determined by the MTT assay using human ovarian adenocarcinoma (Skov-3), glioblastoma (U87), human dermal fibroblasts (HDF), and human colorectal adenocarcinoma (CaCo-2) cell lines. The antimicrobial activity of methanolic extracts was tested on gram-negative (Escherichia coli and Pseudomonas aeuriginosa) and gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) using the in vitro minimum inhibition concentration method (MIC). Enzyme inhibition activity of R. acetosella methanol extract was measured spectrophotometrically against acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes. Results: The findings showed that the major components of the methanol extract content were luteolin-7-O-glucoside (1.599 m/L), polydatin (91,024 m/L), and shikimic acid (0.773 m/L). It was determined that the extract and standard antioxidant (a-tocopherol) results in DPPH center dot, and ABTS center dot + tests performed to determine the antioxidant activity were close to each other, and this value was more effective than the standard antioxidant (alpha-tocopherol) in the CUPRAC test. These results suggested that the plant's antioxidant potential was higher when compared with reference antioxidant compounds. It was determined that the methanol extract of R. acetosella had a weaker effect on the growth of the tested microorganisms than the antibiotics used as standard. The activity of the GST and AChE enzymes was found to be severely inhibited by the methanol extract of R. acetosella. Conclusion: Based on these findings, R. acetosella L. is a medicinal and commercially beneficial plant that warrants further investigation.Article Citation - WoS: 5Citation - Scopus: 7Diagnosis of schizophrenia based on transformation from EEG sub-bands to the image with deep learning architecture(Springer Science and Business Media Deutschland GmbH, 2023) Türk, Ömer; Aldemir, Erdoğan; Acar, Emrullah; Ertuğrul, Ömer Faruk; Tuerk, OemerElectroencephalogram is a low-cost, non-invasive, and high-entropy signal and thus has huge potential for clinical diagnosis of neurological diseases and brain–computer interface applications. Schizophrenia is one of the most severe diseases that show behavioral manifestations that are easily uncovered by specialists. In this context, the electroencephalogram analysis becomes more important for the automatic diagnosis of schizophrenia disease in the clinical process. In this study, a deep learning architecture, namely ResNet, aims to classify schizophrenia is proposed. The proposed system transforms wavelet sub-bands of the electroencephalogram into two-dimensional image space, which is considered the main unique contribution of the study. Thus, the disease indicators and features included in images could be figured out. Moreover, a discussion on the class activation maps was made to give a wide perspective on the features related to the disease. The proposed system was implemented on a large-scale electroencephalogram database containing records from unhealthy and healthy patients in various phases. The ResNet was implemented in three modes to give a thorough perspective in terms of the metrics of the diagnosis accuracy. The proposed system achieves 92.94% diagnosis accuracy rate, and the result shows that the proposed transformation-based solution is owing to the features related to schizophrenia diseaseArticle Citation - WoS: 2Citation - Scopus: 3Effect of Auricular Acupressure in Management of Constipation in Palliative Care Patients(Sage Journals Home, 2023) Bıçak Ayık, Derya; Can, Gülbeyaz; Ayik, Derya BicakObjectives: This experimental randomized-controlled study was performed to define the efficacy of auricular acupressure (AA) in the management of constipation developing in palliative care patients. Methods: According to the pre-prepared randomization list, 44 patients were included in the experimental group and 46 patients were included in the control group. Routine clinical treatment and care implementation were maintained in the patients in both groups. AA was performed for 4 weeks in patients in the experimental group. During the study, to determine the complaints of the patients regarding constipation, the information in the daily patient chart was examined at least 5 times by interviewing with the patient/patient's relative in the clinic and/or via phone call, and the results were recorded in the patient chart and data collection forms. The independent variable of the study is AA application, and the dependent variables are constipation and quality of life. Results: It was determined that there was no statistically significant difference between the daily defecation frequency of the 2 groups during the first 11 days. However, after the 12th day, the daily stool frequency of the experimental group was higher compared to the control group and this difference obtained between the 2 groups was statistically significantly different. AA was effective in decreasing laxative use. Conclusion: This intervention increased stool frequency, reduced physical and psychosocial symptoms, anxieties, and improved stool satisfaction and it was an effective approach to improving the quality of life. It is recommended that the daily use of AA should be evaluated. The healthcare providers including nurses, patients, and patient relatives should be trained regarding AA.Article Citation - WoS: 2Citation - Scopus: 3The effect of body mass index on complications in cardiac implantable electronic device surgery(WILEY, 2023) Güzel, Tuncay; Demir, Muhammed; Aktan, Adem; Kılıç, Raif; Arslan, Bayram; Günlü, Serhat; Altıntaş, Bernas; Karahan, Mehmet Zülkif; Özbek, Mehmet; Aslan, Burhan; Arpa, Abdulkadir; Coşkun, Mehmet Sait; Altunbaş, Mahsum; Tüzün, Rohat; Akgümüş, Alkame; Karadeniz, Muhammed; Aydın, Saadet; Güzel, Hamdullah; Aslan, Selen Filiz; Söner, Serdar; Taş, Ahmet; Ertaş, FarukBackground: Cardiac implantable electronic device (CIED) procedures are prone to complications. In our study, we investigated the effect of body mass index (BMI) on CIED-related complications. Methods: 1676 patients who had undergone CIED surgery (de novo implantation, system upgrade, generator change, pocket revision or lead replacement) at two heart centers in Turkey and met the study criteria were included in our study. For analysis of primary and secondary endpoints, patients were classified as non-obese (BMI < 25 kg/m2), overweight (25 ≤ BMI < 30 kg/m2), and obese (BMI ≥ 30 kg/m2). The primary endpoint was accepted as cumulative events, including the composite ofclinically significant hematoma (CSH), pericardial effusion or tamponade, pneumoth- orax, and infection related to the device system. Secondary outcomes included each component of cumulative events. Results: The rate of cumulative events, defined as primary outcome, was higher in the obese patient group, and we found a significant difference between the groups (3.0%, 4.3%, 8.9%, p = .001). CSH and pneumothorax rates were significantly higher in the obese patient group (0.3%, 0.9%, 1.9%, p = .04; 1.0%, 1.4%, 3.3%, p = .04, respectively). According to our multivariate model analysis; gender (OR:1.882, 95%CI:1.156–3.064, p = .01), hypertension (OR:4.768, 95%CI:2.470–9.204, p < .001), BMI (OR:1.069, 95%CI:1.012–1.129, p = .01) were independent predictors of cumulative events rates. Conclusions: Periprocedural complications associated with CIED (especially hematoma and pneumothorax) are more common in the group with high BMI.Article Citation - WoS: 3Citation - Scopus: 3THE EFFECT OF COOKING AND COLD STORAGE PROCESSES ON FLORFENICOL RESIDUES IN MUSCLE TISSUES OF STURGEON (Acipenser gueldenstaedtii) REARED IN BLACK SEA(Pakistan Journal of Agricultural Sciences, 2021) Gürbüz, Semra; Baydan, Emine; Türe, Mustafa; Taçbaş, Erkan; Akbulut, Bilal; Özcelep, TunaThis research was performed to determine the effect of boiling, grilling and cold storage processes on florfenicol residues in muscle tissues of sturgeons. A total of 16 sturgeons, 10 of which have received single dosage of florfenicol at 10 mg kg(-1) bw day(-1) level and remaining 6 have not received any florfenicol were used in this study. The analyses were performed by HPLC. The mean recovery rate and repeatability pooled-RSD r% of analytical method for florfenicol analysis of sturgeon muscle were determined as 83.4 +/- 1.07% and 17% respectively. The florfenicol levels were 40.30 +/- 8.23% in the muscle tissue of boiled fish, 57.80 +/- 7.46% in the boiling juice, 101.10 +/- 4.01% in the grilled tissue and 78.01 +/- 15.40% and 62.36 +/- 11.60% in the muscle tissues of fishes, which were stored at -20 degrees C, on the 20th and 50th days respectively. The initial florfenicol level in the fish muscle was significantly reduced (P<0.05) by boiling and cold storage processes. A decrease occurred in florfenicol level in boiling process due to the transfer from muscle tissue to boiling juice, and there was no decrease in the florfenicol level as a result of grilling.
