Öğe The comparison of the effects of post-activity performance enhancement on foot plantar pressure and vertical jump in traditional set and cluster set training configurations(MRE Press, 2025) Kale, Mehmet; Boyacı, Abdurrahman; Tolali, Ali Berkay; Yol, Yeliz; Ayaz, Ezgi; Tutar, Murat; Başoğlu, Umut DavutBackground: There is no study about the effects of post-activity performance enhancement on foot plantar pressure and vertical jump in different set configurations. This study aimed to compare the effects of post-activity performance enhancement on foot plantar pressure and vertical jump in traditional set and cluster set training configurations. Methods: The study included 27 volunteer university students (age: 20.0 ± 1.2 year, height: 180.2 ± 6.9 cm, body weight: 76.0 ± 11.8 kg). Static foot plantar pressure (SFPP), countermovement jump (CMJ), and squat jump (SJ) were performed as pre-tests 8 min after the half-squat 1 repetition maximum (HS 1RM) test. After pre-tests, 12 reps of training were performed with 70% of the HS 1RM by varying the training configurations of 1 × 12 reps traditional set (TS) on the 4th day, 3 × 4 reps cluster set 1 (CS1) with 30 s rest on the 8th day, and 6 × 2 reps cluster set 2 (CS2) with 10 s rest on the 12th day. Post-tests were performed in the following of each configuration. Repeated Measures Analysis of Variance (ANOVA) was used for the statistical comparison of the tests in four different time intervals. Results: There were no statistically significant SFPP differences in four different time periods, while statistically significant differences were found in the CMJ (p < 0.001) and SJ (p = 0.002). Pairwise comparisons showed that CMJ pre-test (CMJP RE ) had statistically significant differences with CMJT S, CMJCS1 and CMJCS2 . There were also differences between SJP RE and SJCS1, SJT S and SJCS2 for the SJ (p < 0.05). Conclusions: In conclusion, based on the results of the study, it is recommended to use any of the TS, CS1 and CS2 configurations to increase CMJ and to use the CS1 configuration to increase SJ as a performance enhancement at 8 min post-activity.Öğe Adaptation of the quality of sibling experience scale for individuals with special needs siblings into Turkish: a methodological study(Dokuz Eylül University Institute of Health Sciences, 2025) Özdemir, Tuğba; Karadağ, Gülendam; Bektaş, MuratPurpose: The relationship between siblings, which is a lifelong bond, affects both the individual with special needs and their healthy sibling in many ways. This study was conducted to do the Turkish validity and reliability study of the Siblings' Experience Quality Scale (SEQS). Material and Methods: The study was carried out with individuals who were aged over 18 and had a sibling enrolled in the Guidance and Research Center of a province. Shapiro-Wilk normality test, Pearson correlation analysis, content validity index, Cronbach's Alpha coefficient, McDonald's omega test, confirmatory factor analysis, and t-test were used in data analysis. Results: The healthy siblings of 171 students with special needs voluntarily participated in the study. The scale explained 54.8% of the total variance. The omega reliability coefficient value for the overall scale was determined as 0.81. As a result of CFA, the fit indices were found as X2=247.893, df=128, X2/df=1.93, RMSEA=0.074, GFI=0.86, IFI=0.85, NFI=0.73, TLI=0.81, CFI=0.84, and AGFI=0.819. Conclusion: The SEQS was proven to be a valid and reliable measurement tool in the Turkish population.Öğe Exercise-induced muscle oxygenation changes in fibrosing interstitial lung diseases: a near-infrared spectroscopy study(Mattioli 1885, 2025) Pehlivan, Esra; Zeren, Melih; Özcan, Zeynep Betül; Karaahmetoğlu, Fulya Senem; Demirkol, Barış; İlhan, Umut; Ataç, Amine; Çetinkaya, ErdoğanBackground: The impact of fibrosing interstitial lung disease (F-ILD) on the oxygenation of peripheral and respiratory muscles during exercise remains poorly understood. Specifically, it's unclear whether regional blood flow influences exercise capacity in these patients, and if so, to what degree. Objectives: This study aimed to investigate changes in oxygenation and blood flow volume of the intercostal (IC) and quadriceps femoris (QF) muscles during exercise in patients with F-ILD. Methods: Muscle oxygenation (SmO2) and total haemoglobin (tHb) changes of IC and QF were measured in 36 F-ILD patients using near-infrared spectroscopy (NIRS) during six-minute walking test (6MWT). Resting, minute-by-minute change, and average data were analyzed. Results: At rest, SmO(2)was significantly higher in IC compared to QF (p<0.001). When adjusted for SmO(2)at rest, SmO(2)at the different time points during 6MWT, average SmO(2)during 6MWT, and lowest SmO2 during 6MWT did not differ between QF and IC muscles. Also, SmO(2 )did not vary significantly during 6MWT in either QF (F=2.193) or IC muscle (F=1.262). THb increased more in QF than in IC. THb of IC inversely correlated to respiratory functions and 6MWT distance. Conclusion: Peripheral and respiratory muscle oxygenation in F-ILD seems to be normal. However, blood flow volume in exercising muscle, not muscle oxygenation, may be a contributing factor to exercise intolerance. Patients with poorer respiratory function may require excessive blood flow in their respiratory muscles which in turn may limit the blood flow available for exercising peripheral muscles.Öğe Can Vitamin D reduce the need for SSRI by modulating serotonin synthesis? : a review of recent literature(Springer Nature, 2025) Bostan, Zekiye Zeynep; Bulut, Melike Sare; Gezmen Karadağ, MakbulePurpose of Review: This study aims to analyze the effects of vitamin D on serotonin synthesis, release, and function in the brain, and to explore its relationship with various psychiatric disorders. Recent Findings: The hormone calcitriol plays a vital role in regulating a multitude of biological processes within the human body. Its deficiency can lead to significant adverse effects on overall health and well-being, including physical and psychological consequences. Evidence indicates that vitamin D may exert influences through receptors in the brain, modulating serotonin production and influencing emotional and cognitive processes. Recent studies propose that elevated serum vitamin D may enhance mood and alleviate depressive states. The impact of vitamin D on cognitive function and behavior remains an area of ongoing investigation. This literature review analyses the available evidence on how vitamin D intake impacts the severity of illness and medication requirements in diverse psychiatric disorders. A review of the literature suggests that there may be a correlation between vitamin D and serotonin, which could potentially contribute to more favorable outcomes in the context of illness. Vitamin D may increase the amount of serotonin in the synaptic gap, which is the intended use of selective serotonin reuptake inhibitors (SSRIs), with its effect on the increase in serotonin release. Summary: According to reports, vitamin D supplementation in conjunction with SSRI group medication provides an additive effect for the management of psychiatric disorders.Öğe Thermodynamics analyses of ionic GO plus MXene/EG plus water hybrid nanofluid in a circular tube including a novelty vortex generator(Elsevier Science SA, 2025) Gürsoy, Emrehan; Gürdal, Mehmet; Yıldırım, FurkanThis research explores the thermo-hydraulic efficiency and entropy generation characteristics of an innovative hybrid nanofluid (GO+MXene/EG+water) flowing through a circular tube, enhanced by a novel vortex generator incorporating dimpled fins with spherical, elliptical, and trapeze geometries placed on wave tapes. The vortex generators effectively disrupted boundary layers, thereby improving thermal performance across all configurations. The novelty of this research lies in the first-time examination of MXene-based hybrid nanofluids in conjunction with vortex generators to assess thermo-hydraulic performance and entropy generation. Due to its excellent thermal conductivity and stability, the hybrid nanofluid was studied under laminar flow conditions, with Reynolds numbers ranging from 500 to 2000. The findings reveal that the GO+MXene/EG+water hybrid nanofluid enhances the convective heat transfer coefficient by 20.32% while increasing the pressure drop by 25.85% compared to the base fluid. Besides, GO+MXene/EG+water hybrid nanofluid reduced the thermal entropy generation at the rate of 60.6%. Among the studied fin geometries, spherical dimpled fins demonstrated the highest heat transfer improvement, with a normalized heat transfer ratio of 1.02, whereas trapeze fins exhibited relatively lower enhancement. This research contributes to the scientific community by providing valuable insights into the optimization of heat exchangers and other industrial thermal systems, facilitating enhanced heat transfer with reduced entropy generation. The study's findings have significant implications for future investigations on the integration of hybrid nanofluids and extended surface heat transfer enhancement techniques. Notably, the results offer a foundation for the development of novel designs that leverage hybrid nanofluids to improve energy efficiency in industrial systems.Öğe The effect of internet addiction on surgical nurses' malpractice tendencies: Turkish sample(Springer Nature, 2025) Gezginci Akpınar, Elif; Orhan, Büşra Nur; Göktaş, SonayBackground This study aimed to determine the effect of surgical nurses' internet addiction on their malpractice tendencies. Methods The descriptive cross-sectional study included 1051 nurses working in the surgical awards of 10 hospitals in Istanbul. Data were collected using a descriptive characteristics form, the Internet Addiction Scale, and the Malpractice Tendency Scale. An increase in the score on the internet addiction scale indicates that internet addiction increases. In contrast, an increase in the score on the malpractice tendency scale indicates that malpractice tendency decreases. Data were analyzed using independent groups t-test, one-way ANOVA test, Pearson correlation and linear regression analyzes with IBM SPSS Statistics version 22.0 software. Results A weak negative correlation was found between the surgical nurses' total scores on the Internet Addiction Scale and Malpractice Tendency Scale (r=-0.422 p < 0.001). Internet addiction total score was also negatively correlated with malpractice tendency subscale scores for medication and transfusion administration safety (r=-0.450 p < 0.001); infection prevention (r=-0.416 p < 0.001); patient monitoring, device, and material safety (r=-0.321 p < 0.001); fall prevention (r=-0.325 p < 0.001), and communication (r=-0.332 p <= 0.001). In linear regression analysis, an increase in internet addiction overall and in the lack of control subscale was associated with greater malpractice tendency (ss=-0.422 and ss=-0.243, respectively). Internet addiction explained a total of 17.7% of the total change in malpractice tendency (R2 = 0.177). Conclusion Surgical nurses showed increased malpractice tendency as their internet addiction level increased. This relationship was seen in all domains of malpractice, including medication and transfusion administration safety, infection and fall prevention, communication, and patient monitoring, device, and material safety. It is recommended that in-service training be planned for conscious internet use to limit the time nurses spend on the internet during working hours.Öğe Structural and electrical properties of CuO-doped NaNbO3 ceramics(Walter de Gruyter GmbH, 2025) Berksoy Yavuz, Ayşe; Danışman, MuratCeramics are one of the key materials of today’s industry. The manufacturing technique used for preparing the ceramics greatly affects the material’s structural and electrical properties. Therefore, the elements and their distribution in the material as well as understanding their relation with the manufacturing process are the key factors for managing the expected outcome. In this study, NaNbO3 ceramics and the effect of CuO-doping in solid state calcination process was investigated. For this purpose pure, 0.5 mol.% and 1.0 mol.% CuO-doped sample discs were prepared. Crystallite size, strain, atomic structure, lattice parameters and atomic occupancies of the material were calculated by using X-ray diffraction patterns combined with Rietveld analysis. Additionally, the samples were investigated with the scanning electron microscopy technique to observe the effect of CuO doping. For electrical characterization, dielectric constant and tangent loss measurements were carried out on samples. As a result, it was concluded that CuO doping affected the crystal structure of the NaNbO3 which triggered the changes in its electrical behavior. The observed effects were more pronounced at 1.0 mol.% CuO content.Öğe The acute effects of motor imagery combined with action observation breathing exercise on cardiorespiratory responses, brain activity, and cognition: a randomized, controlled trial(Wiley-Hindawi, 2025) Atak, Ebrar; Ataç, AmineBreath and brain activity have been integral to daily life since time immemorial. Cognition and cardiorespiratory responses are closely interlinked, necessitating further investigation into their dynamics. The potential benefits of combining motor imagery (MI) and action observation (AO) based breathing exercises in rehabilitation have not been fully explored. This study was aimed at assessing the acute effects of MI combined with AO on cognitive function and cardiorespiratory responses. Thirty-three healthy adults were randomized into MI combined with AO breathing (MI+AO), active respiratory exercise (ARE), and control groups, with equal distribution across groups. Electroencephalography (EEG) data were collected using a Muse EEG headband, and cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) while imagining activities were measured via the Kinesthetic and Visual Imagery Questionnaire (KVIQ). Significant improvements in the Timed Up and Go (TUG) test and systolic blood pressure were observed in the ARE group (p < 0.05), alongside improvements in MoCA and KVIQ scores (p < 0.05). EEG data revealed significant decreases in delta and theta power at the temporoparietal (TP) location in the ARE group (p < 0.05). These findings suggest that MI and AO, when combined with respiratory exercises, may serve as effective passive strategies to support cognition and cardiorespiratory function, particularly in individuals who struggle to actively participate in pulmonary rehabilitation.Öğe Lactate kinetics and fatigue dynamics in elite taekwondo athletes during a 30-second continuous jump protocol(Projack, 2025) Kaya, Mehmet Zeki; Shahidi, Seyed HoutanBackground: This study examines lactate kinetics and performance declines during a 30- second BOSCO jump protocol in elite Taekwondo athletes, providing insights into anaerobic performance and recovery. Methods: Anthropometric data, including age, height, and weight, were collected, with averages of 21.2 years (+/- 2.0), 181.4 cm (+/- 4.8), and 70.6 kg (+/- 4.3). Fatigue-induced changes were assessed by measuring jump heights, contact times, and power outputs using the Witty Jump Mat (Italy) during the first and last 5 seconds of the protocol. Blood lactate concentrations were measured with the Lactate Scout 4 (Germany) at baseline, immediately postexercise, and at 3, 6, and 9 minutes post-exercise. Results: Significant declines were observed in jump height (mean decrease = 13%, p = 0.01) and power output (mean decrease = 15%, p = 0.02), alongside an increase in contact time (mean increase = 18%, p = 0.03), reflecting the impact of fatigue on explosive performance. Athlete B showed the greatest reduction in jump height (31.36%), revealing notable inter-individual variability in fatigue resilience. Blood lactate levels increased significantly from baseline (mean = 0.78 +/- 0.08 mmol/L) to peak post-exercise (mean = 3.16 +/- 1.19 mmol/L, p < 0.001) and subsequently declined. Lactate clearance rates were calculated as 40.5% at 3 minutes, 60.5% at 6 minutes, and 65.5% at 9 minutes post-exercise. Athlete D exhibited the fastest clearance rate (72%, p = 0.02), while Athlete C demonstrated delayed recovery. Conclusions: The findings underscore the need for tailored conditioning programs to optimize anaerobic performance and recovery in Taekwondo athletes. Future research should explore the effects of targeted training on anaerobic capacity and competition readiness in combat sports.Öğe Search for central exclusive production of top quark pairs in proton-proton collisions at √s=13 TeV with tagged protons(Springer, 2024) Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Bergauer, T.; Chatterjee, S.; Damanakis, K.; Dragicevic, M.A search for the central exclusive production of top quark-antiquark pairs (t (t) over bar) is performed for the first time using proton-tagged events in proton-proton collisions at the LHC at a centre-of-mass energy of 13TeV. The data correspond to an integrated luminosity of 29.4 fb(-1). The t (t) over bar decay products are reconstructed using the central CMS detector, while forward protons are measured in the CMS-TOTEM precision proton spectrometer. An observed (expected) upper bound on the production cross section of 0.59 (1.14) pb is set at 95% confidence level, for collisions of protons with fractional momentum losses between 2 and 20%.Öğe Non-invasive Raman and XRF study of Mīnā’ī decoration, the first sophisticated painted enamels(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Colomban, Philippe; Şimşek Franci, Gülsu; Ngo, Anh-Tu; Gallet, XavierMīnā’ī wares, crafted during the 12th–13th centuries, represent some of the earliest examples of sophisticated painted enamel decoration by potters. Due to the thinness of these enamel layers, their detailed characterization remains challenging, even with the use of advanced techniques, such as Proton-Induced X-ray Emission (PIXE) analysis and Rutherford Backscattering Spectrometry (RBS). This study provides the first combined non-invasive analysis, using X-ray fluorescence (XRF) and Raman spectroscopy, of five shards attributed to mīnā’ī wares. For comparison, two İznik shards from the 17th century, which feature similarly styled but thicker enamel decorations, were also analyzed. Interestingly, the mīnā’ī paste was found to contain lead and tin, suggesting the use of a lead-rich frit in its composition. This finding was confirmed through micro-destructive analysis, using Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM–EDS). Elements, such as rubidium (Rb), strontium (Sr), yttrium (Y), and zirconium (Zr), produced significant XRF signals and effectively distinguished mīnā’ī wares from İznik wares. A uniform tin-rich glaze, measuring 300–500 µm in thickness, was used as a base layer for the much thinner painted mīnā’ī enamels. The colored areas (blue, turquoise, red, green, black, white, eggplant) revealed the presence of various coloring agents and phases, such as spinels, chromite, and ions like Cu2+ and Co2+, as well as opacifiers like cassiterite and lead–calcium/potassium arsenates. Two distinct cobalt sources were identified: one associated with arsenic and the other with manganese and nickel. These cobalt sources are comparable to those used in İznik pottery. For the first time, boron was detected in the blue enamel of mīnā’ī wares.Öğe Investigation of inspiratory muscle training efficiency before bronchoscopic lung volume reduction: a randomized controlled trial(Sociedad Espanola de Neumologia y Cirugia Toracica (SEPAR), 2025) Pehlivan, Esra; Çetinkaya, Erdoğan; Özcan, Zeynep Betül; Karaahmetoğlu, Fulya Senem; Çörtük, Mustafa; Ataç, Amine; Çınarka, HalitIntroduction: Pulmonary rehabilitation (PR) is recommended prior to bronchoscopic lung volume reduction (BLVR) procedures to optimize patient outcomes. However, there's a lack of clear guidance on PR content. The aim of our study is to examine the effect of adding inspiratory muscle training (IMT) to standard PR before BLVR on exercise capacity, dyspnea, fatigue level and quality of life. Methods: Sixty-four patients were randomly assigned to either the PR Group (PRGr) or the PR with IMT group (IMTGr). Both groups underwent an 8-week standard PR program, including breathing exercises, muscle strengthening, and walking. Additionally, IMTGr received IMT sessions. Outcome measures comprised six-minute walking distance (6MWD), maximal inspiratory and expiratory pressures (MIP, MEP), peripheral muscle strength, modified Medical Research Council dyspnea score, fatigue symptom scale, spirometric parameters, Saint George Quality of Life Questionnaire (SGRQ), International Physical Activity Questionnaire Short Form (IPAQ-SF), and Hospital Anxiety and Depression Scale. Results: Our study found no significant difference in exercise capacity improvement between IMTGr and PRGr. However, IMTGr showed significant improvement in MIP compared to PRGr. Both groups experienced improvements in dyspnea, fatigue, and depression scores, as well as enhancements in 6MWD, MEP, peripheral muscle strength, IPAQ-SF and SGRQ scores. Conclusion: Adding IMT to PR did not show a significant difference between groups among BLVR-eligible patients. However, improved respiratory muscle strength may have positive clinical implications. Further research is needed to explore short and long-term effects.Öğe Does the use of protective face masks affectemporomandibular joint function?(Professional Medical Publications, 2025) Özdemir Görgü, Sena; Yıldırım, Yasin; Kaya, Pınar; Ergezen, Gizem; Uzuner, EdaObjective: Long-term mask use can trigger or exacerbate various health issues. This prospective experimental study evaluated the impact of protective face masks on masseter muscle activity and temporomandibular joint (TMJ) function reported by participants. Methods: This prospective, experimental tudy was conducted to investigate the effect of face masks on TMJ function, we used surface electromyography to assess masseter muscle activity at rest, during maximum contraction of the masseter muscle, and while reading a text. We also evaluated the intensity of the masseter muscle pain using an algometer. The participants underwent these evaluations at the Istanbul Medipol University between July and October 2022. Results: The study included 24 female participants with an average age of 28.5±5.40 years. After at least five hours of daily N95 mask use, a significant increase in masseter muscle activity was observed at rest and during speech (p=0.01; p=0.04, respectively). However, no significant changes in the maximum contraction of masseter muscle or pain threshold were observed (p>0.05). Conclusion: This study found that the use of N95 mask is associated with restricted TMJ movements and discomfort, and an increase in its use is associated with restricted TMJ movements, discomfort, and increased masseter muscle activity. Questions regarding mask-wearing-related habits should be included in the routine lifestyle assessment of patients who report TMJ complaints.Öğe Relationship between nutritional literacy and healthy life skills of university students(John Wiley and Sons Inc, 2025) Karadağ, Gülendam; Bilgiç, Dilek; Öztürk, Nuray; Özdemir, TuğbaHealth literacy is important for maintaining healthy diets and lifestyles. This study examined the relationship between nutrition literacy and healthy life skills of university students. This study was a descriptive and correlational design. The students' Food and Nutrition Literacy Scale knowledge sub-dimension mean score was found to be 10.30 +/- 2.11, at the limited knowledge level, the attitude sub-dimension mean score was 49.32 +/- 7.26, at the limited attitude level, and the behaviour sub-dimension mean score was 31.04 +/- 5.71, at the limited level. The mean Scale of Healthy Life Skills in University Students score of the university students was 62.96 +/- 9.99, at a moderate level. Multiple regression analysis showed that the mean scores obtained from the attitude and behaviour sub-dimensions, studying in the Faculty of Nursing, being 18 years old, and studying in the first or second year were the main variables influencing the healthy life skills of university students. The food and nutrition literacy of the students was limited and their healthy life skills were at a moderate level. As the food and nutrition literacy of the students increased, their healthy life skills became more positive.Öğe Effect of telerehabilitation based high intensity interval training on biochemistry parameters and symptoms in patients with fibromyalgia(Dokuz Eylül University, 2025) Akıl Ağdere, Selin; Pehlivan, Esra; Kat, Ezgi; Helvacı, Nazlı; Kural, Alev; Vural, MeltemPurpose: The aim of this study was to evaluate the effect of telerehabilitation-based high intensity interval training (HIIT) on biochemistry parameters and disease symptoms in fibromyalgia patients. Fibromyalgia syndrome (FMS) is a chronic musculoskeletal disease of unknown etiology accompanied by symptoms such as pain, hyperalgesia, sleep disorders, fatigue and mood disorders. Material and Methods: 33 fibromyalgia patients were randomly assigned as HIIT (n = 11), moderate-intensity continuous training (MICT)(n = 11) and control group (CG)(n = 11). While the patients in the study groups were given upper extremity exercise with telerehabilitation for 6 weeks, no intervention was applied to the CG. Disease symptoms and blood parameters were evaluated before and after treatment. Results: After the treatment, significant changes were found in the results of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase GSH(Px), right hand grip strength, pressure pain threshold, fatigue severity and disability in the HIIT group, and in the results of SOD, myeloperoxidase (MPO), left hand grip strength and fatigue severity in the MICT group (p<0.05).Öğe Investigation of the effects of 8-week tabata training on physical performance in amputee football players(Dokuz Eylül University, 2025) Sarı, Özkan; Tutar, MuratPurpose: The aim of this study was to investigate the effects of 8-week tabata training on physical performance in amputee football players. For this purpose, 24 male football players who played in amputee football Super league and had at least 5 years of amputee football history participated in the study voluntarily. Material and Methods: The athletes participating in the study were divided into 2 groups of 12 each as control group (CG) and tabata group (TG) by simple random method. While the TG applied an 8-week tabata exercise protocol during the normal football season, the CG continued only football training. Tabata protocol was applied as 4 sets 2 times a week for 8 weeks. Height, weight, waist, hip, standing long jump, vertical jump and yoyo tests were performed as pre-test before 8 weeks and post-test after 8 weeks. Dependent sample t test was used to determine whether there was a difference between the pre-test and post-test of each group. Results: According to the pre-post test data between the groups; statistically significant differences were found in the final weight (-1.92±0.38), final VKI (-1.05±0.19), final SLJ (33.91±7.51), final VJ (7.66±1.54), and final Yoyo (1.437±0.26) measurements of TG and KG (p>0.05). Conclusion: Tabata protocol applied for 8 weeks will be very useful to be used more in the development of aerobic and anaerobic endurance skills which are very important in amputee football players.Öğe Anıt tasarım dili kuruluşunda temsilin aracı olarak biçim ve biçimsel örgütlenme düzeni(Anadolu Üniversitesi, 2024) Kolbay, Sevda DuyguAnıtlar, ontolojik açıdan sanat ve mimarlık disiplininin arakesitinde yer almaktadır.

To this end, 312 healthcare workers serving in Istanbul were reached through convenience sampling and data was generated through face-to-face interviews. A preliminary scale comprising 33 items was initially created. Following expert opinions and pilot study phases, six items were removed from the draft scale, leaving 27 items. Exploratory factor analysis was initially applied to the data, resulting in the removal of nine more items from the scale, thus reducing the number of items to a final scale of 18. The final scale was grouped into three factors: "General Xenophobia," "Occupational Xenophobia," and "Cultural Xenophobia." The items obtained following exploratory factor analysis were subjected to confirmatory factor analysis. The analysis demonstrated that the model obtained fits the data perfectly. The Cronbach's alpha value for the developed scale was found to be 0.905. In conclusion, the developed scale was found to be a valid and reliable measurement tool for the measurement of xenophobic attitudes among healthcare workers.Öğe Efficacy of ursodeoxycholic acid in reducing the necessity of cholecystectomy due to pre-existing and subsequently formed gallstones in patients who underwent laparoscopic sleeve gastrectomy(BMC, 2025) Demirpolat, Muhammed Taha; Çelikkaya, Muhammet Oğuz; Ertekin, Süleyman Çağlar; Başak, Fatih; Şişik, AbdullahBackgroundIn this study, we aimed to investigate whether ursodeoxycholic acid (UDCA) would reduce the necessity of cholecystectomy in patients diagnosed with asymptomatic gallstones after laparoscopic sleeve gastrectomy (LSG) and in patients diagnosed with asymptomatic gallstones before LSG.MethodsBetween July 2020 and November 2022, at least 2-year follow-ups of patients who underwent LSG for obesity were retrospectively analyzed. Patients with pre-existing asymptomatic gallstones during preoperative evaluation, those with UDCA treatment (group 1), and observation group (group 2). Patients with newly formed gallstones in postoperative outpatient clinic follow-up, those with UDCA treatment (group A), and those without UDCA treatment (group B).ResultsA total of 425 patients included. At the end of the first year, patients who had newly formed gallstones after LSG had a higher total weight loss percentages (TWL%) (39.8 +/- 6.1) compared to those who did not develop gallstones (37.9 +/- 7.4), which were statistically significant (p = 0.004). Among patients who developed gallstones postoperatively, UDCA treatment was associated with a significantly lower cholecystectomy rate in patients with newly formed gallstones postoperatively (p = 0.025), while no significant difference was shown in patients with preoperative gallstones (p = 0.631).ConclusionUDCA is a promising option for reducing the need for cholecystectomy in patients with post-LSG gallstones, but it appears ineffective for pre-existing gallstones.Öğe Search for new physics in the lepton plus missing transverse momentum final state in proton-proton collisions at √s=13 TeV(Springer, 2022) Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Bergauer, T.; Chatterjee, S.; Dragicevic, M.; del Valle, A. EscalanteA search for physics beyond the standard model (SM) in final states with an electron or muon and missing transverse momentum is presented. The analysis uses data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected with the CMS detector at the LHC in 2016-2018 and corresponding to an integrated luminosity of 138 fb(-1). No significant deviation from the SM prediction is observed. Model-independent limits are set on the production cross section of W' bosons decaying into lepton-plus-neutrino final states. Within the framework of the sequential standard model, with the combined results from the electron and muon decay channels a W' boson with mass less than 5.7 TeV is excluded at 95% confidence level. Results on a SM precision test, the determination of the oblique electroweak W parameter, are presented using LHC data for the first time. These results together with those from the direct W' resonance search are used to extend existing constraints on composite Higgs scenarios. This is the first experimental exclusion on compositeness parameters using results from LHC data other than Higgs boson measurements.
