Relationship Between E-Health Literacy and Healthy Lifestyle Behaviours of Turkish Health Sciences Students
(Emerald Publishing, 2025) Çakır, Furkan; Ozturk, Sergen; Gerçek, Hasan; Eryildiz, Ezgi; Kartal, Gokce; Polat, Mine Gulden
Purpose: E-health literacy (EHL) and healthy lifestyle behaviours (HLBs) are important for individuals receiving health education. Health professionals of the future should be conscious, e-health literate and develop HLBs. The aims of this study were to determine the EHL and HLBs of university students receiving health education and to examine the relationship between them. Design/methodology/approach: A total of 1,454 health sciences students, between the ages of 18–27, were included in the study. Participants' data were collected online via Google Forms. Participants' EHL levels were assessed with the E-Health Literacy Scale. Participants' HLB were assessed with the Healthy Lifestyle Behaviours Scale II. Findings: Positive weak correlation was found between EHL and HLB (p < 0.001, r = 0.329). EHL scores of bachelor’s degree students were higher than associate degree students (p = 0.004). HBL total score bachelor’s and associate degree student scores were similar (p = 0.714). Originality/value: This article addresses an important gap in understanding health sciences students' online reading habits about health and their relationship to HLB. Considering that there is a positive relationship between EHL and HLBs of students in the health departments of universities, increasing the EHL levels of students will help to increase HLBs. © 2025, Emerald Publishing Limited.

(Elsevier, 2023) Ede, Seren; Özbeyli, Dilek; Erdogn, Omer; Cevik, Ozge; Kanpalta, Fatma; Ercan, Feriha; Senerg, Goksel
Background and study aims: This study aimed to investigate the possible protective effects of parsley extract (Petroselinum Crispum; PC) against oxidative liver damage caused by bile obstruction in rats. Material and methods: Bile duct ligation (BDL) method was used to induce liver injury in rats. The rats were divided into the three groups each consisting of 8 rats; Sham-operated control (C), bile duct ligated + saline treated (BDL), and BDL + PC treated groups. PC extract was given at a dose of 2 g/kg orally for 28 days. Aspartate amino transferase (AST), alanin amino transferase (ALT), and bilirubin levels were analyzed in sera. In order to determine free radicals in liver injury, luminol and lucigenin chemiluminescence tests used. Oxidative stress was evaluated through superoxide dismutase, glutathione, malondialdehyde, Na+/K+-ATPase and 8-hydroxy guanosine levels. Furthermore, inflammation marker myeloperoxidase, apoptosis marker caspase-3, and fibrosis markers TGF- beta and hydoxyproline were investigated. The liver tissues were also examined for histological evaluations.Results: While PC treatment decreased AST and ALT levels which increased with BDL, oxidant damage parameters also decreased with this treatment. Conclusion: The present study, which is the first research for PC extract on cholestasis induced liver damage, demonstrated that PC extract could be a potential therapeutic agent against liver fibrosis and need further studies.

Effects of Computer-Based Balance Exercises on Balance, Pain, Clinical Presentation and Nerve Function in Patients With Diabetic Peripheral Neuropathy: a Randomized Controlled Study
(International Society of Musculoskeletal and Neuronal Interactions, 2024) Reyhanıoglu, D.A.; Yıldırım, G.; Sengun, I.Ş.; Kara, B.
Objective:To evaluate the use of a computer-based biodex balance exercise system (BBS) on balance, neuropathic pain, clinical presentation and nerve function in patients with diabetic peripheral neuropathy (DPN). Methods: A total of 32 participants with DPN were randomly assigned in a 1:1 ratio to an intervention group (IG) or control group (CG). The IG performed exercises using the BBS twice weekly for 8 weeks, while CG were informed regarding diabetes self-management. At baseline and after study completion, participants underwent balance (postural stability and fall risk) and neuropathic pain assessment (DN4 questionnaire) and were screened using the Michigan Neuropathy Screening Instrument and nerve conduction test. Results: Among the baseline participants, 14 in the IG and 13 in the CG completed the study. Balance training improved postural stability (overall, p<0.001), fall risk (p<0.001), neuropathic pain (p=0.01) and symptoms (p<0.001), and clinical presentation (p=0.02), but not nerve function, within the IG. At follow-up, IG displayed significantly improved stability (p<0.001) and fall risk (p=0.02) and decreased neuropathic symptoms (p=0.01) compared to the CG. Conclusion: Computer-based balance exercises improve balance, pain, and clinical presentation of DPN, but not nerve function, in patients with DPN.

Prevalence of Obesity in Prepubertal and Pubertal With Turkish Population Type 1 Diabetes
(Springer Japan Kk, 2021) Ozkaya, Volkan; Eren, Erdal; Ozgen Ozkaya, Sebnem; Denkboy Ongen, Yasemin
To determine the prevalence of prepubertal and pubertal obesity in children and adolescents with type 1 Diabetes Mellitus (Type 1 DM). One hundred fifty children and adolescents aged 6-18 years with Type 1 DM who attended the Pediatric Endocrinology Polyclinic and were diagnosed with type 1 DM were included in the study. Tanner staging was used to estimate pubertal status. Age- and gender-specific body mass index (BMI) percentile between 85 and 95% was accepted as overweight and > 95% as obese. It was determined that the overweight prevalence rates in children and adolescents with type 1 DM were 13.3% and the obesity rate was 14.3%. It was found that while the overweight prevalence rates (14.1%) were higher in males, the obesity prevalence was higher in females (19.0%). The obesity prevalence rates at the prepubertal and pubertal stages were found to be 17.1% and 13.8%, respectively. The obesity prevalence at the pubertal stage was higher in girls (22.4%) than boys (3.9%) (p < 0.05). The rates both of overweight and obesity in boys decreased from prepubertal to pubertal periods, while those rates increased in girls. Our results indicated that the obesity prevalence in prepubertal and pubertal children and adolescents with type 1 DM was higher compared to healthy peers in the literature. The authors believe that the risk factors for obesity in this population should be determined and obesity-prevention programs for diabetes should be prepared.

Synthesis, Antimicrobial Evaluation, and Molecular Modeling Studies of New Thiosemicarbazide-Triazole Hybrid Derivatives of (s)-naproxen
(Wiley-v C H verlag Gmbh, 2022) Han, M. Ihsan; Ince, Ufuk; Gunduz, Miyase Gozde; Kucckguzel, S. Guniz
The discovery of new antimicrobial molecules is crucial for combating drug-resistant bacterial and fungal infections that pose a dangerous threat to human health. In the current research, we applied a molecular hybridization approach to synthesize original thiosemicarbazide-triazole derivatives starting from (S)-naproxen (7a-7k). After structural characterization using FT-IR, H-1-NMR, C-13-NMR, and HR-MS, the obtained compounds were screened for their antimicrobial activities against Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Candida albicans ATCC 10231 and their isolates, as well. Although all compounds were found to be moderate antimicrobial agents, in general, their antibacterial activities were better than antifungal effects. Among the tested compounds, 7j carrying nitrophenyl group on the thiosemicarbazide functionality represented the best MIC value against S. aureus isolate. Finally, molecular docking studies were performed in the active pocket of S. aureus flavohemoglobin to rationalize the obtained biological data.
The Moderating Role of Gender in Perceived Discrimination Levels and Political Participation of Turkish Women
(Walter de Gruyter Gmbh, 2025) Ozkilicci, Gokce; Yamaner, Onur
This study explores the relationship between women's political participation, perceived discrimination, and gender dynamics in Turkey. Political participation embodies an individual's aspiration to influence societal transformation and contribute to decision-making processes that shape communities. However, women's engagement in these processes has long been hindered by deeply rooted societal norms and systemic barriers. The primary objective of this research is to examine how perceived discrimination impacts women's political participation and to assess whether gender perceptions moderate this relationship. Data were collected from 313 female university students aged 18-58, utilizing the Political Participation Scale, Gender Perception Scale, and Perceived Discrimination Index. The results demonstrated a significant positive correlation between perceived discrimination and political participation, with gender perception acting as a key moderator. Women with stronger gender equality beliefs were more likely to recognize discrimination and engage in political activities. These findings emphasize the critical role of cultural, educational, and institutional strategies in enhancing women's political visibility and addressing systemic barriers. The study provides a robust foundation for developing egalitarian policies to promote women's active participation in politics, fostering a more inclusive democratic landscape.
Ameliorative Effects of Myrtus Communis L. Extract Involving the Inhibition of Oxidative Stress on High Fat Diet-Induced Testis Damage in Rats
(Taylor & Francis Ltd, 2024) Coskunlu, Busra; Koroglu, M. Kutay; Hersek, Irem; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha
The possible protective effects of Myrtus communis L. (MC) extract on a high fat diet (HFD)-induced testicular injury in a rat model were investigated using histological and biochemical methods. Wistar albino rats were divided into three groups: a standard diet control group; a HFD group; and an HFD+MC group. The HFD and HFD+MC groups were fed with a HFD for 16 weeks. MC extract (100 mg/kg) was given orally five days a week to the rats in the HFD+MC group during the last four weeks of the experiment. Leptin, triglyceride, high-density lipoproteins, cholesterol, estrogen, testosterone, LH and FSH were analyzed in blood serum. Sperm parameters were evaluated from the epididymis. Testicular morphology, proliferative, apoptotic and NADPH oxidase-2 (NOX2)-positive cells were evaluated histologically. Testicular oxidative stress parameters were analyzed biochemically. In the HFD group, lipid and hormone profiles were changed, abnormal spermatozoa, degenerated seminiferous tubules with apoptotic and NOX2-positive cells were increased in number, and sperm motility and germinal proliferative cells decreased compared to the control group. Moreover, testicular malondialdehyde, 8-hydroxy-2-deoxyguanosine and myeloperoxidase levels increased, whereas glutathione and superoxide dismutase levels decreased in the HFD group compared to the control group. All these histological and biochemical features were ameliorated by MC treatment of HFD-fed rats. In conclusion, HFD caused alterations in sperm parameters and testicular morphology by increasing oxidative damage and apoptosis. MC extract may have potential protective effects by inhibiting oxidative damage.

Comparison of Total Antioxidant Capacities and Phenolic Constituents of Grapes Cultivated in Turkey for Wine Production
(Taylor and Francis Ltd., 2025) Karaman Ersoy, Ş.; Vural, T.; Sözgen Başkan, K.; Tütem, E.
Grapes are renowned for their health-promoting properties due to polyphenols, particularly anthocyanins in red grapes and flavonols in white grapes. This study evaluated the total antioxidant capacities (TAC) of specific grape varieties (Sultaniye, Chardonnay, Shiraz, Carignan, Alicante Bouschet, and Merlot) using the CUPRAC (CUPric Reducing Antioxidant Capacity) and ABTS/HRP (2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)/horseradish peroxidase) methods. Additionally, total phenolic, flavonoid, and anthocyanin contents were determined via Folin Ciocalteu, AlCl3/NaNO2, and pH differential methods. Primary phenolic compounds were identified with High-Performance Liquid Chromatography-Photodiode Array (HPLC-PDA). TAC values of the grape juices (mmol Trolox L−1) ranked as Alicante > Shiraz > Sultaniye > Carignan > Merlot > Chardonnay by CUPRAC, and Shiraz > Alicante > Merlot > Carignan ≥ Sultaniye > Chardonnay by ABTS/HRP and for skin extracts (mmol Trolox g−1), Carignan > Alicante > Shiraz > Merlot > Chardonnay > Sultaniye by CUPRAC, and Carignan > Shiraz > Alicante > Merlot > Chardonnay > Sultaniye by ABTS/HRP. The study demonstrated a strong correlation between phenolic composition and TAC values in grape samples, with anthocyanins as the predominant family contributing significantly to TAC. Varietal and intra-fruit differences in specific phenolic compounds were found to account for variations in observed TAC levels. Specifically, grape skin samples showed a more robust correlation between antioxidant capacity and total phenolic content (r = 0.986) than grape juices (r = 0.777). These findings underscore the considerable variation in antioxidant potential among grape varieties and emphasize the critical role of phenolic composition in the health-related benefits of grape consumption. © 2024 Taylor & Francis Group, LLC.

(Natl inst Public Health, 2022) Ozturk, Servet; Ozel, Ayse Serra; Ergen, Pinar; Senbayrak, Seniha; Agalar, Canan
Objectives: Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are the two leading viruses that cause the greatest number of virus-related morbidities in the world. HIV/HBV coinfection is correlated with high morbidity and mortality. For this particular reason hepatitis B vaccination is crucial for people living with HIV. Methods: Patients who are being followed-up for HIV/AIDS and who have received a hepatitis B vaccine in 4 HIV clinics over a 5-year time period have been studied. Our multi-centered, retrospective, cross-sectional and observational study investigates factors that affect hepatitis B vaccination immune response of individuals living with HIV. The patients have been studied for the parameters such as age, sex, CD4 count at the time of diagnosis or vaccination, HIV-RNA levels, comorbidities, vaccine dosage, success of immunization after vaccination, and the demographics of the patients who have and have not developed immunity. Results: Of 645 patients that are being followed-up in our clinics, 158 received hepatitis B vaccine; 39 of these 158 patients have been excluded from the study because they did not fulfil the inclusion criteria. Finally, 119 patients were evaluated in the study, 17 of the patients (14.3%) were females and 102 (85.7%) were males. The median age was 41.11 +/- 10.09 (min-max: 18-75). Twenty-three of the patients (19.3%) were at the stage of AIDS during diagnosis while 80.7% were at the stage of HIV infection. Ninety-one of the patients (76.5%) have been administered a single dose hepatitis B vaccine on the standard 0, 1st, 6th month vaccination schedule, whereas 23.5% were administered a double dose on the same vaccination schedule. When further evaluated to find whether the patient was able to develop sufficient immunity (anti-HBs >= 10), it was found that the immune response was statistically significantly higher in the patients whose CD4 count was greater than 200 at the time of the first diagnosis and vaccination (p = 0.05 and p = 0.001, respectively). The patients have also been evaluated according to the number of doses they received (1 vs. 2). The immune response of the patients who received two doses was statistically significantly higher (p = 0.041). Conclusion: We can conclude that in the patients with CD4 count less than 200 at the time of their diagnosis and vaccination a high dose recombinant hepatitis B vaccine should definitely be administered as the normal dose and higher dose have similar side effect profiles and the higher dose provides greater immunity.
Why Do Nurses Transfer from Private Hospitals to Public Hospitals in Turkiye? A Descriptive Cross-Sectional Survey Study Considering Working Conditions, Compulsory Citizenship, Presenteeism, and Burnout
(Wiley, 2025) Turan, Suzan; Seren, Arzu K. Harmanci
This study investigates the reasons behind the transition of nurses from private hospitals to public hospitals in Turkiye, focusing on working conditions, compulsory citizenship behavior, presenteeism, and burnout. The study used a descriptive cross-sectional survey design. The sample consisted of 224 nurses who previously worked in private hospitals and were employed in public hospitals at the time of data collection. Researchers collected data via a questionnaire incorporating demographic questions and validated scales on compulsory citizenship behavior, presenteeism, and burnout. Parametric and nonparametric comparison tests were used to compare participants' experiences in private and public hospitals regarding working conditions. There were statistically significant differences between the groups (p < 0.05). Also, participant nurses' negative organizational behavior experiences scores (compulsory citizenship behavior, presenteeism, and work-related burnout) statistically significantly differed (p < 0.05), considering their scores based on private hospital and public hospital experiences. The study concluded that nurses worked longer and took less leave in private hospitals. Participant nurses also reported that they exhibited more compulsory citizenship presenteeism and experienced a higher rate of work-related burnout while working in private hospitals.

A Single-center's Early Surgical Outcomes of Living Donor Liver Transplantation
(Elsevier Science inc, 2023) Anilir, Ender; Oral, Alihan; Atasoy, Alp; Civan, Hasret Ayyildiz; Topcu, Feyza Sonmez; Bayramoglu, Mert; Unal, Bulent
Background. Living donor liver transplantation (LDLT) has become an increasingly common surgical option because the number of cadaveric donors is insufficient to fulfill the organ needs of patients facing end-stage cirrhosis. Many centers are investigating different surgical techniques to achieve lower complication rates. We aimed to examine our complication rates in light of demographic data, graft data, and perioperative findings as a single-center experience. Methods. The study included one hundred and three patients who underwent LDLT for endvein, and bile anastomosis type rates; anhepatic phase; cold ischemia time; operation time; and blood product transfusion rates were analyzed. Biliary complications in patients with single or multiple biliary anastomoses, right or left liver transplants, and with or without hepatic artery thrombosis were analyzed statistically. Results. There was no significant difference in biliary complications between patients who underwent single or multiple bile anastomosis (P = .231) or patients receiving right lobe and left lobe transplants (P = .315). Although there was no statistically significant difference in the rate of portal vein thrombosis between the regular and reconstructed portal vein anastomosis groups (P = .693), the postoperative portal vein thrombosis rate was statistically higher in patients with left lobe transplants (P = .044). Conclusions. Vascular and biliary complication rates can be reduced with increasing experience.
In Vivo and In Silico Evaluation of the Effects of Parsley (Petroselinum Crispum L.) Extract on Small Intestinal Tissue in Scopolamine-Induced Cognitive Dysfunction Model
(Wiley-VCH Verlag GmbH, 2025) Ertik, Onur; Sacan, Ozlem; Sener, Goksel; Pazarbasi, Seren Ede; Yanardag, Refiye
The brain-small intestine connection has become important in neurodegenerative diseases in recent years. In particular, the discovery of the relationship between Alzheimer's disease (AD) and the small intestine and the examination of the effects of AD on this tissue are important in this respect. Our study aimed to understand the effects of the experimentally created AD model in rats on the small intestinal tissue and the protective effect of the extract prepared from parsley leaves (PE). The experimental animals were divided into four groups in the study; Control, Scopolamine (Scop), Scop + PE and Scop + Galantamine (GAL). Oxidative stress parameters and activities of some important enzymes were examined in small intestinal tissues taken as a result of the experimental protocol. Additionally, in silico studies were carried out for bioactive molecules found in parsley leaves using data obtained from in vivo enzyme activity results. It was found that parameters examined for the damaged group, Scop, were reversed by PE and GAL treatment. As a result of in silico studies, it was determined that oxypeucedanin and phylloquinone had higher binding affinity than rutin for acetylcholinesterase (AChE). It has been observed that oxidative damage in the small intestine due to AD can be treated by the PE.

Isokinetic Knee Muscular Strength Is Associated With Hematologic Variables in Female Modern Dancers
(Spanish Assoc Sports Performance Analysis-aearedo, 2018) Agopyan, Ani; Tekin, Demet
It is important to expose the risk factor in injury in the context of the health and the careers of dancers. Female are at greater risk of developing anemia than men, yet scarce data exist on anemia associated outcomes in female dancers. The aim of the present study was to investigate the relationships between bilateral isokinetic knee extensor and flexor muscles strength, and biochemical hematologic parameters in female modern dancers. Concentric isokinetic peak torque [(PT)-N.m], peak torque % body weight [(PT% BW)-N.m.kg(-1)], average peak torque [(AVGPT)-N.m] and total work [(TW)-J)] of the knee extensor and flexor muscles were measured at a velocity of 60 degrees, 180 degrees and 300 degrees s(-1). To determine hematological parameters [red blood cell count (RBC), hematocrit (Hct), and Hb] were determined. The dancers of LHG and HHG had significant differences (p <= 0.05) for hematological parameters. HHG dancers' strength production in extensors muscles of PT, TW and AVGPT in non-dominant left leg (p <= 0.05) were significantly higher than LHG dancers. There were significant (p <= 0.05) negative correlations between TW (300 degrees s(-1)) of left leg extensor muscles and RBC, Hct and Hb variables. Isokinetic knee muscular strength is associated with hematologic variables in female modern dancers. The current study provides evidence that the low-level hematologic parameters has decreased performance on torque production of extensors knee muscles in non-dominant leg during isokinetic muscle strength endurance in female modern dancers.

Melatonin Improves Liver and Pancreatic Tissue Injuries in Diabetic Rats: Role on Antioxidant Enzymes
(Springer int Publ Ag, 2023) Ertik, Onur; Bayrak, Bertan Boran; Sener, Goksel; Yanardag, Refiye
PurposeMelatonin (Mel) is an indolamine mainly synthesized by the pineal gland and many other organs. It plays an important role in scavenging free radicals and stimulating antioxidant enzymes. The goal of this study was to investigate the effect of Mel and/or insulin treatment on oxidative liver and pancreas injuries in diabetic rats.MethodsMale Wistar albino rats were assigned into 5 groups. Group I: control animals. Group II: diabetes was induced via a single dose of STZ (60 mg/kg) administered intraperitoneally. Group III: diabetic rats treated with Mel (10 mg/kg/day). Group IV: diabetic rats given insulin (6U/kg) subcutaneously. Group V: diabetic rats that received insulin and Mel at the same dose and time. After 12 weeks of the experiment, the animals were decapitated, liver and pancreas tissues were collected.ResultsThe results indicated that reduced glutathione levels in liver and pancreatic tissue decreased, while protein carbonyl, advanced oxidized protein products and lipid peroxidation levels were elevated in diabetic group. Antioxidant enzyme activities decreased in liver tissues but increased in pancreatic tissues of the diabetic group. Administration of Mel, insulin or Mel + insulin reversed these biochemical changes in the diabetic animals.ConclusionThis work shows that in long-term oxidative stress conditions caused by STZ-induced diabetes, either Mel or Mel + insulin administration may improve the deteriorated oxidant/antioxidant system in both the liver and pancreas tissues. These results suggested that Mel alone or Mel + insulin treatments might have a significant role in protecting against liver and pancreatic damage in STZ diabetic rats via different antioxidant effects.
Decentralisation as Resistance: Web3’s Potential in Countering Digital Censorship and Redefining Cyber Sovereignty
(Eotvos Lorand Tudomanyegyetem, 2024) Eldem, T.
The Internet, initially celebrated as a bastion of freedom and openness, is increasingly becoming a domain of control, surveillance, and regulation by both states and private entities. The rise of state control and regulation of the Internet, along with the private sector’s expanding control over information, poses significant challenges to the ideals of freedom and openness that once defined the Internet. This article examines the transformation in Internet governance from a state of minimal regulation to a heavily controlled environment by both governments and corporations and explores how the blockchain technology and decentralised architecture underlying Web3 promise to redefine Internet governance and resist censorship. Through a mixed-method approach that synthesises insights from computer science, political science, and legal studies, the paper argues that public blockchains challenge Internet Corporation for Assigned Names and Numbers’ (ICANN) traditional control over DNS and significantly reduce the ability of centralised entities to exert control over content and communication, thereby enhancing freedom of expression and resisting censorship. The ability of Web3 to fully realise this potential is, however, dependent on overcoming complex technical and regulatory challenges. © 2024, Eotvos Lorand Tudomanyegyetem. All rights reserved.

Objective An accurate and reliable measurement of proprioception is important in the evaluation of the cervical. The aim of this study is to investigate the validity and reliability of a new method using Horizontal Plane Target Platform (HPTP) to assess Head Repositioning Accuracy (HRA) for Cervical Proprioception (CP). Methods HRA values of 86 healthy volunteers (21.01 +/- 2.16 yrs.) were measured through AOS PropPoint laser apparatus device on HPTP, Frontal Plane Target Platform (FPTP), and also CROM device to assess test-retest reliability and validity. Results The test-retest measurements of HPTP reliability was (ICC (left) =0.69, ICC (right) =0.74; SEM (left) =0.28, SEM (right=) 0.36; MDC (left) =1.85, MDC (right) =2.02 95%CI) were moderate for both side. Correlation with the CROM device results was moderate for both side (r=0.75 for left size, r=0.83 for right side), and the absolute values demonstrate concordance between results using the Bland-Altman method. Conclusions HRA measurements performed with a laser apparatus on HPTP which we developed can be used as an alternative method in CP evaluation.

A Multi-Criteria Decision-Making Approach for Greenovative Supplier Selection
(Univ Cincinnati industrial Engineering, 2022) Buyukselcuk, Elif Caloglu; Tozan, Hakan; Vayvay, Ozalp
In today???s rapidly changing business environment, green and innovative (greenovative) activities have become indispensable elements of sustainable supply network management. Realization of this fact obliges firms to consider greenovative as well as traditional criteria in determining their supplier. This study provides a new greenovative systematic approach to supplier selection for small and medium-sized enterprises. Fuzzy multi-criteria decision-making (FMCDM)-based techniques were used to determine the most appropriate supplier with the proposed model. To show the usability of the model, an application was carried out on an automotive supply company. Analytic Hierarchy Process (AHP) and Fuzzy Analytic Hierarchy Process (FAHP) approaches were used to calculate the weights of the supplier selection criteria. After determining criteria weights, different multi-criteria decision-making (MCDM) techniques that are often encountered in the literature were used to identify the best supplier.
Unraveling the Persistent Renal Impact of Intrauterine Growth Restriction and Catch-Up Growth: Integrating Morphological Insights with Metabolomic Profiling
(Springer, 2025) Esrefoglu, Mukaddes; Koktasoglu, Fatmanur; Bayindir, Nihan; Cimen, Fatma Bedia Karakaya; Kirmizikan, Seda; Hekimoglu, Emine Rumeysa; Selek, Sahabettin
The study aimed to investigate the long-term effects of IUGR and consequent catch-up growth on metabolic health by using a comprehensive approach that included histopathological, immunohistochemical, biochemical, and metabolomics analyses. Sprague-Dawley pregnant rats either undergo bilateral uterine artery ligation or a sham surgery on the 19th day of gestation. The offspring reached catch-up growth, kidney samples were collected at postnatal weeks 2, 4, and 8 for analysis. IUGR rats exhibited a spectrum of changes including reduced glomeruli number, proliferating cell number, altered oxidative stress markers, various enzymes involved in Krebs cycle, mitochondrial dynamics, and energy metabolism. Examination of the 8-week-old cohort identified a broader spectrum of metabolic alterations, notably in the biosynthesis of phenylalanine, tyrosine, and tryptophan, phenylalanine, tyrosine, glyoxylate, dicarboxylate, pyruvate, alanine, aspartate, and glutamate metabolism, glycolysis/gluconeogenesis and citrate (TCA) cycle. Our metabolomics analysis provides insights into the potential disease susceptibility of individuals born with IUGR, including obesity, diabetes, hypertriglyceridemia, cardiovascular diseases, and mental retardation. These findings underscore the intricate interplay between intrauterine conditions and long-term metabolic health outcomes, highlighting the need for further investigation into preventive and therapeutic strategies to mitigate the risk of metabolic diseases in individuals with a history of IUGR.
The Effect of Myrtus Communis L. Extract on Nephrolithiasis Model in Rats
(Kare Publishing, 2024) Ertas, B.; Dorucu, D.; Gulerturk, O.; Sen, A.; Cevik, O.; Cetinel, S.; Sener, G.
OBJECTIVE: Nephrolithiasis is a common urological disease that can lead to renal failure. Oxidative stress has been shown to be a contributing factor for nephrolithiasis and many agents have been studied to prevent and treat oxidative stress-related nephrolithiasis and renal damage. Myrtus communis (MC) extract has been shown to be an important antioxidant in different animal models. In this study, MC extract was administered preventively or therapeutically to rats with kidney stones, and its effectiveness was investigated. METHODS: Wistar albino rats were divided into four groups (n=8); control (C), ethylene glycol (EG), EG+preventive MC, and EG+curative MC groups. The nephrolithiasis model was created by adding 0.75% EG to drinking water for 8 weeks. Ultimately, 24-hour urine was collected to measure calcium, citrate, and creatinine levels. After decapitation, kidney tissues were harvested for histological analyses, measurement of osteopontin and 8-hydroxydeoxyguanosine (8-OHdG) levels, and N-acetyl-β-glucosaminidase (NAG), myeloperoxidase (MPO) and caspase-3 activities. RESULTS: In 24-hour urine samples, calcium, citrate and creatinine levels were decreased in the EG group, while oxalate levels were increased and in treatment groups these parameters returned to control levels. MPO, 8-OHdG, caspase-3 and NAG activity were significantly increased in tissue and these changes were reversed in both MC groups. Histological findings also supported the biochemical parameters. CONCLUSION: MC can reduce oxidative stress and histopathological changes in kidney tissues in rat nephrolithiasis model when used as either a preventive or therapeutic agent. If supported with further clinical trials, MC might have clinical implications in preventing oxidative renal cell injury and ultimately kidney stone formation. © 2024 by Istanbul Provincial Directorate of Health.
