    A new turn off flurecnloset NIR probe for hypochlorous acid and its applications
    (Tubitak Scientific & Technological Research Council, 2025) Ibrahimova, Ayten; Önem, Ayşe Nur; Altun, Mehmet; Yeşil, Emin Ahmet; Baysal, Aslı; Saygın, Hasan; Soyocak, Ahu; Özyürek, Mustafa
    Hypochlorous acid (HOCl) is a potent nonradical oxidant involved in various physiological processes, particularly within the human immune system. In this study, we introduce a novel, rapid, and highly efficient fluorometric method for the detection of HOCl. The method utilizes a near-infrared (NIR)-based fluorescent probe, NIR-QBH, which is characterized by its high sensitivity and chemical stability. NIR-QBH, containing olefinic C=C bonds, exhibits strong NIR emission at 660 nm (lambda ex = 618 nm). The detection mechanism relies on the oxidation of the C=C bond in the NIR-QBH structure by HOCl, resulting in the formation of non-fluorescent products. With a detection limit of 0.23 mu M, the probe demonstrates a fast response time of 4 min. Glutathione (GSH), an essential biothiol, was employed as a reference HOCl scavenger, and its HOCl scavenging activity was evaluated with an IC50 value of 8.97 mu M. Furthermore, the developed fluorometric assay was successfully applied for the detection of HOCl in fetal bovine serum (FBS) and aqueous solutions.

    (MA Healthcare Ltd, 2025) Orhan, Büşra Nur; Göktaş, Sonay
    Objective:The study was carried out to compare the effect of transparent covers and elastic fixation bands used in peripheral venous catheter fixation on microbiological colonisation in patients in intensive care. Method:This experimental randomised controlled study was conducted with patients treated in the Anesthesia and Reanimation Unit (an intensive care unit, ICU) of a training and research hospital in Istanbul between January 2019 and May 2020. Participants were divided into two equal groups: intervention: (catheters fixed with a transparent cover) and control (catheters fixed with an elastic fixation band) by the block randomisation method (CONSORT). After 72 hours, the catheters were removed aseptically and cultures were collected from the catheter tips. The roll plate technique was used and colony growth of >= 15 colony forming units was considered significant. The data of the study were collected using the 'Patient Information Form' and 'Catheter Follow-up and Result Form'. Results:A total of 60 patients were included in the study (30 in each group). It was found that the effect of the microbiological colony-forming microorganism species, and the area of catheter insertion on microbiological colonisation, were not statistically significantly different between the two groups (p>0.05). Conclusion:The findings of this study showed that both fixation methods can be used with effective nursing care in the treatment of patients in ICUs.

    Experimental and optimization study of nanofluid utilized PVT systems with hydrocarbon based PCM: an energetic-exergetic approach
    (Elsevier Ltd, 2025) Kurtoğlu Sontay, Kübra; Öğüt, Elif; Ustaoğlu, Abid; Özkan, Doğuş; Kurşuncu, Bilal
    Cooling of photovoltaic thermal (PVT) systems is crucial for enhancing electrical efficiency by reducing the operating temperature of photovoltaic modules. Elevated temperatures negatively affect the performance of PV cells, leading to a decline in energy conversion efficiency. Photovoltaic thermal (PVT) systems, hybrid technologies that generate electricity and heat, are crucial for efficient energy conversion. This study uniquely explores the performance of a PVT system by integrating phase change materials (PCMs) and nanofluids in PVT systems combined with optimization analysis. By combining these advanced cooling methods, both electrical and thermal efficiencies are significantly optimized, demonstrating the potential for improved energy conversion in PVT systems. Within this scope, three identical systems–water-cooled, nanofluid-cooled, and a combination of nanofluid cooling with PCM- were analyzed regarding electrical, thermal, and exergy efficiencies. Identical panels were placed side by side and tested. Additionally, an optimization analysis has been conducted to enhance the performance of each panel by evaluating the thermal and electrical efficiency values obtained from experimental data based on system parameters and levels. In addition, thermogravimetric analysis and differential scanning calorimetry were conducted to determine the melting point of the Hydrocarbon-Based PCM. Compared with traditional methods, these analyses conducted in conjunction with the experimental study provide a more reliable basis for performance evaluation studies of PVT systems. The results of the experimental study showed that Nanofluid-Integrated PVT with Hydrocarbon-Based PCM achieved 11.7 %, 11.6 % and 10.6 % higher electrical efficiency, overall exergy and electrical exergy respectively, compared to the water-cooling method. Additionally, a 6.6-fold increase in thermal efficiency and a 4.4-fold increase in overall efficiency were observed. Similarly, compared to the nanofluid cooling method, this combination provided 4.9 %, 5.9-fold and 3.47 % improvements in the electrical, thermal and overall exergy efficiencies metrics. The results of the optimization analysis revealed that the combination of PCM and nanofluids ensures greater stability in electrical efficiency values under high-temperature differences. It was also observed that solar irradiance is the most influential parameter affecting efficiency. The obtained results demonstrate that the nanofluid-cooled system integrated with PCM has a significant impact on enhancing the performance of PVT systems. The combined use of nanofluid and PCM considerably improves all efficiency parameters.

    (Elsevier B.V., 2025) Özer, Gökhan; Tütük, İbrahim; Cingöz, Umut Can; Koç, Ebubekir; Karaaslan, Ahmet
    In this study, AlSi10Mg samples were produced using the Powder Bed Laser Fusion (PBLF) method with standard parameters. Specimens were retrogression and re-aging (RRA) heat-treated at various conditions. The effects of the RRA heat treatments on the properties of PBLF parts were examined by microstructure, electrical conductivity, and electrochemical corrosion tests. Microstructural properties were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray (EDS) analysis. The results showed that after RRA heat treatment, the electrical conductivity of the material decreased slightly, and the corrosion resistance increased.

    (MRE Press, 2025) Kale, Mehmet; Boyacı, Abdurrahman; Tolali, Ali Berkay; Yol, Yeliz; Ayaz, Ezgi; Tutar, Murat; Başoğlu, Umut Davut
    Background: 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.

    Deep learning algorithm for dessert recognition and nutritional evaluation
    (Food Reseach Institute, 2025) Yusun, Sevilay; Yılmaz, Onur; Tarlak, Fatih
    Food recognition systems are crucial for healthcare and the food industry, aiding in diet tracking, personalised meal planning, and promoting nutritional awareness. This work develops a software interface that recognises food products using deep learning algorithms, and announces their nutritional values and gastronomic characteristics. Specifically, photographs of various desserts were captured in a restaurant setting, and the classification performance of two deep learning models, GoogleNet and ResNet-50, was analysed. Both models achieved high accuracy rates exceeding 99.6 %, with ResNet-50 demonstrating superior performance due to its lower error rates, higher accuracy, and faster learning capabilities. Based on these results, the interface was developed using ResNet-50 to provide consumers with detailed gastronomic information about desserts and support healthier dessert choices. At present, the resulting software is limited to the 23 dessert items on the menu of Healin restaurant (Nisantasi, Istanbul, Turkey), and the way they look in that particular restaurant, but the scope could be expanded in the future. This innovative approach enhances consumer awareness about healthy eating while offering a competitive edge for the food industry by effectively meeting consumer expectations.

    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, Erdoğan
    Background: 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.

    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, Makbule
    Purpose 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.

    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, Furkan
    This 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.

    The effect of internet addiction on surgical nurses' malpractice tendencies: Turkish sample
    (Springer Nature, 2025) Gezginci Akpınar, Elif; Orhan, Büşra Nur; Göktaş, Sonay
    Background 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.

    Structural and electrical properties of CuO-doped NaNbO3 ceramics
    (Walter de Gruyter GmbH, 2025) Berksoy Yavuz, Ayşe; Danışman, Murat
    Ceramics 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.

    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, Amine
    Breath 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.

    Lactate kinetics and fatigue dynamics in elite taekwondo athletes during a 30-second continuous jump protocol
    (Projack, 2025) Kaya, Mehmet Zeki; Shahidi, Seyed Houtan
    Background: 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.

    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, Xavier
    Mīnā’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.

    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, Halit
    Introduction: 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.

    (Professional Medical Publications, 2025) Özdemir Görgü, Sena; Yıldırım, Yasin; Kaya, Pınar; Ergezen, Gizem; Uzuner, Eda
    Objective: 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.

    (John Wiley and Sons Inc, 2025) Karadağ, Gülendam; Bilgiç, Dilek; Öztürk, Nuray; Özdemir, Tuğba
    Health 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.
