The use of copper phthalocyanine pigments as blue colorants in gelatin films for aquatic food packaging
(Kocaeli University, 2025) Bayıl, Sibel; Çetinkaya, Turgay; Alanalp, Mine Begüm
In this study, Copper (Cu) phthalocyanine pigments, coded PD1 and PD2, were characterized, and the possibility of using them as blue colorants in gelatin-based materials for aquatic packaging was evaluated. Synthesized phthalocyanine pigments were compared with imported commercial PB15:1 (control) in terms of Fourier Transform Infrared Spectroscopy (FTIR), high-performance liquid chromatography (HPLC) results, Cu, and ash content. It was found that the synthesized PD1 and PD2 samples were the ones closest to the commercial powder in terms of FTIR peaks, Cu amount, and HPLC results. The selected sample coded PD1 at 0.5 wt% with respect to the solution was further added to gelatin-containing solutions containing 10% and 5% glycerol, and dried films of GL10 and GL5 were obtained, respectively. Although the 10% glycerol-added film showed better color properties, L, a, b, Hue angle, and Chroma parameters were insignificant (p>0.05). Tensile tests and creep/recovery curves showed that GL10 had 107% higher elongation at break, 29% lower Young’s modulus, and higher strain values compared to GL5, making it softer and more flexible. Deformation parameters such as hardness, chewiness, and gumminess were also compared at different deformation rates for the selected GL10 sample. Results indicated that blue pigment-added gelatin films can be used in aquatic food product packages.
Finite element analysis and production of a balance robot designed to be used in the field of advertising
(Kerim ÇETİNKAYA, 2025) Coşkun, Yusuf; Aydın, Diyar Can; Aktoz, Halil; Özyılmaz, Lale
This study presents the finite element analysis and prototype development of a self-balancing robot designed for applications in the advertising sector. The structural behavior and dynamic properties of the robot were analyzed using static, modal, and rigid body simulations in ANSYS software. Static analysis confirmed the mechanical durability of the robot by evaluating the forces acting on the motors and body, while modal analysis identified potential resonance conditions. Notably, in the third vibration mode, a deformation of 330.24 mm at 52.169 Hz was observed, indicating a critical resonance issue. To enhance structural efficiency, topology optimization was applied to the outer casing, resulting in a 14% reduction in mass (from 0.45392 kg to 0.39069 kg) while maintaining structural integrity. During the experimental phase, the prototype successfully demonstrated autonomous movement using integrated distance sensors. However, initial tests revealed a wobbling motion due to insufficient motor power, which will be addressed in future iterations by incorporating higher-torque motors. The proposed robot has the potential to serve as an interactive advertising tool, capable of attracting attention through dynamic motion and engaging promotional content display. Future work will focus on enhancing stability and refining control algorithms to improve performance in real-world advertising environments.
Efficient and facile synthesis of hydroxy-functionalized hexagonal boron nitride nanosheets by ion-assisted liquid phase exfoliation method
(Eskişehir Osmangazi University, 2025) Yaman Uzunoğlu, Gülşah
Hexagonal boron nitride (h-BN) nanosheets have attracted significant attention due to their unique mechanical, thermal, and electronic properties. Their biocompatibility, thermal conductivity, chemical stability, and versatility make them indispensable in cutting-edge technologies. Hydroxy-functionalized h-BN nanosheets (h-BNNS-OH) exhibit immense potential in various applications, including electrochemical energy storage, drug delivery systems, and heat spreaders in thermal management systems. This study focuses on the hydrothermally ion-assisted liquid-phase exfoliation of h-BN powder to produce few-layer h BNNS-OH. The exfoliation process involves hydrothermal treatment of bulk h-BN in the presence of concentrated aqueous solution of KOH and NaOH at 180 °C, followed by sonication for dispersion of h-BNNS-OH in water. Characterization of h-BNNSs was performed using powder X-ray diffraction (XRD), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The resulting exfoliated h-BNNSs are hydroxyl-functionalized on their surface. This study demonstrates the effectiveness of the successive execution of the hydrothermal treatment in the presence of excess alkali metal hydroxides and probe sonication as a facile and efficient exfoliation process, resulting in dispersions of h-BNNS-OH in water with remarkably high stability (beyond 9 weeks) and high product yield (17 %) at only one exfoliation cycle.

(Sivas Cumhuriyet University, 2025) Özdemir Olgun, Fatoş Ayça; Demirata Öztürk, Birsen
Defense mechanisms involving antioxidant molecules play a key role in neutralizing free radicals formed in the human body. It is important to determine the content of these molecules, which have become important in human nutrition in recent years, in consumed foods. This study aims to determine the total antioxidant capacity of the barberry (Berberis Crataegina) plant, which is consumed in many regions of Turkiye. For this purpose, firstly, barberry plant samples were collected from Mersin in summer season, the extracts were prepared with different solvents and CERAC method was used to determine the total antioxidant capacities of the samples. The highest value of total antioxidant capacity was obtained by 80 % (v/v) methanol solution for flesh part of the fruit. Total phenolic compound and total antioxidant capacities of the flesh part of barberry samples were calculated as 1.954 mmol gallic acid (GA) g-1 and 1.288 mmol Tr (TR) g-1, by Folin-Ciocalteu method and Cerium Reducing Antioxidant Capacity Assay (CERAC), respectively.

(Gümüşhane University, 2025) Aydoğdu, Ana Luiza Ferreira
Happiness constitutes a fundamental component influencing individuals’ lifelong attitudes and career trajectories. This study aimed to investigate the relationship between subjective happiness and academic engagement among undergraduate nursing students. Employing a descriptive, cross-sectional, and correlational design, the study was conducted with a sample of 350 students. Data were collected through the Subjective Happiness Scale (SHS) and the Utrecht Work Engagement Scale – Short Form for Students (UWES-S-9 ©) and analysed using PSPP version 1.6.2- g78a33a. The mean subjective happiness score was 5.00±1.17, and the mean academic engagement score was 3.75±1.42, indicating moderate levels. Students aged 30 years and older, as well as those with middle or upper-middle income levels, demonstrated significantly higher happiness scores compared to their counterparts aged 20–25 years and those with lower income levels. Furthermore, students who chose the nursing program out of genuine interest and those who indicated a willingness to choose it again exhibited higher scores in both happiness and academic engagement. A significant positive association was observed between subjective happiness and academic engagement. To enhance students’ well-being, implementing social and financial support initiatives, promoting peer mentoring programs, and facilitating experience sharing activities are recommended. Providing comprehensive information about nursing career pathways may also strengthen students’ connection to the profession.

(İstanbul Gelisim University, 2025) Topraksever, Nükte; Özgül Artuç, Gamze
Aim: This study aims to determine the amounts of α-tocopherol (α-toc) and α-tocopheryl acetate (α-tocAc) in soft pharmaceutical capsules and supplements using a chromatographic method. Additionally, method validation parameters for both analytes were evaluated. Method: Analyses were performed using a chromatographic method. As part of the method validation, recovery (% recovery), repeatability (% RSD), linear regression coefficient (R²), limit of detection (LOD), and limit of quantification (LOQ) values were determined. Results: The recovery values were found to be above 95%. Repeatability (%RSD) was calculated as <3%. The linearity (R²) values were obtained as 0.999. For α-toc: LOD: 0.131 µg/mL and 2.228 µg/mL, LOQ: 0.396 µg/mL and 6.752 µg/mL. For α-tocAc: LOD: 0.260 µg/mL, LOQ: 0.787 µg/mL. Conclusion: The chromatographic method used in this study enabled the determination of α-toc and α tocAc with high accuracy and repeatability. This method can be considered a reliable alternative for the analysis of these compounds in pharmaceutical products.
A case study for re-domestication in Turkish translation system: Texier’s Asie Mineur
(Hacettepe Üniversitesi, 2025) Şirin, Said Emre
Anatolia, as the cradle of civilizations, with its rich cultural, historical, and natural heritage, has attracted not only the peoples living on its lands but also travelers, researchers, and scholars from different geographies. This study examines the translations of French archaeologist Charles Texier’s Asie Mineure, written after his travels and observations in 19th-century Anatolia, into Turkish. The Turkish translations of the work are analyzed within the framework of the concepts of re-domestication, cultural textless back translation, and paratextuality. Originally published in French in 1839, the work was translated into Ottoman Turkish in 1923, and later, in 2002, this version was revised, simplified, and adapted into Modern Turkish Language. During this process, various paratexts were added, and editorial modifications were introduced. A striking aspect of the study is that the significant temporal gap between the two translations is reflected in both the linguistic structure of the work and the translation policies applied. Comparative analysis suggests that the agents of the modern Turkish translation system, finding the domestication of the first translation insufficient, may have adopted a re-domestication policy in the second translation. Ultimately, the study argues that it makes an important contribution to understanding the rich translation and cultural activities spanning from the late Ottoman period to the early Republican era, and that it constitutes a valuable case for translation studies. Thus, the work is regarded not only as a written and linguistic translation product, but also as a source reflecting the diversity of translation policies within their historical context.
Topology optimization-based lightweight chassis design: A case study on structural efficiency enhancement for an autonomous scale vehicle
(Dicle University, 2025) Taş, Kerem Ali; Karabıyık, Mehmet Can; Tanrıver, Kürşat; Ak, Mine
This study aims to enhance structural efficiency and achieve material savings by employing the topology optimization method for the lightweight design of an autonomous model vehicle chassis. During the design process, the penalty-based Solid Isotropic Material with Penalization (SIMP) method, available within ANSYS Academic software, was utilized. Initially, a structural analysis of the chassis was conducted, followed by the application of topology optimization based on the finite element method (FEM) results. Through iterative solutions under specified loading conditions and boundary constraints, a mass reduction of approximately 27% was achieved compared to the initial geometry. Despite the reduction in mass, the design maintained its structural integrity. Graphical analyses indicated that the optimization process reached convergence after the fifth iteration, with a stabilized distribution of material. The results demonstrate the potential of topology optimization to develop low-cost, lightweight, yet robust structural solutions, emphasizing its effectiveness as an engineering tool in systems where weight reduction is critical, such as autonomous model vehicles.
Evaluation of the prevalence and location of second mesiobuccal canals in 2100 upper first and second molar teeth: A cone beam computed tomography study
(Inonu University, 2025) Kaplan, Bahar; Adıgüzel, Özkan; Öner Talmaç, Ayşe Gül; Aslan Öztürk, Elif Meltem
It is essential to undertake thorough preparation, debridement and filling of all root canals in order to achieve a clinically successful treatment outcome. A total of 525 CBCT images of both maxillary first and second molars were analyzed. The observations and measurements were positioned 1 millimeter (mm) apically from the pulp base to standardize the methodology for the detection of the second mesiobuccal canal (MB2). To assess the distances between the canals and the relationship between the presence of MB2 and mesiobuccal (MB) root length, MB root length was quantified in millimeters. IBM SPSS Version 21.0 was employed for statistical analyses, with a type I error level of 5% accepted. MB2 was identified in 36.5% of the first maxillary molar (1MM) and second maxillary molar (2MM) teeth of the patients included in the study. When the frequency of MB2 was evaluated according to gender and right-left side, no statistically significant difference was found (p>0.05). When examining the relationship between the presence of MB2 and the length of the MB root, it was observed that only in the left second molars with MB2 present, the root length was slightly shorter. It is our contention that this study will furnish dentists with crucial data that will enhance the efficacy of root canal therapy for these teeth.
Long-term outcomes of extended versus segmental resection for transverse colon cancer: A population-based analysis based on the SEER database
(Galenos Publishing House, 2025) Benlice, Çiğdem; Erkaya, Metincan; Aghayeva, Afag; Özben, Volkan; Görgün, Emre; Atasoy, Deniz; Baca, Bilgi
Objective: To investigate long-term cancer-specific outcomes associated with extended versus segmental colectomy (SC) in patients with stage I-III transverse colon adenocarcinoma using a large, population-based cohort. Material and Methods: Patients who diagnosed with transverse colon cancer undergoing curative-intent colectomy were identified from the surveillance, epidemiology, and end results database (2013-2019). Surgical procedures were categorized as extended colectomy (EC) or SC based on standardized procedural coding. 1:1 propensity score matching was performed to reduce selection bias and balance baseline characteristics. Cancer-specific survival (CSS) was analyzed using multivariable Cox proportional hazards regression. Results: Among 18,799 eligible patients, 58% underwent EC. EC was more frequently performed in individuals with higher tumor stage (p<0.01) and those receiving adjuvant chemotherapy (26% vs. 23%, p<0.01). After matching (n=7.904 in each group), EC was associated with a higher rate of adequate lymphadenectomy (>12 lymph nodes retrieved: 94% vs. 89%, p<0.01). Five-year overall survival did not differ significantly between groups (65.6% for EC vs. 66.9% for SC, p=0.074). However, SC was associated with a modest but statistically significant improvement in CSS (84.3% vs. 81.7%, p<0.01). In adjusted analysis, surgical extent (HR=0.8376, p<0.001), along with age, sex, tumor grade, stage, and lymph node yield, were independently associated with CSS. Conclusion: While EC is more commonly utilized in advanced-stage disease and facilitates higher lymph node retrieval, SC offers comparable—and potentially superior—CSS in selected patients. These findings support the consideration of a tailored surgical strategy based on tumor biology and individual patient characteristics.
The effects of light and vibration on the correction of lower incisor crowding with aligners
(Galenos Publishing House, 2025) Özcan, Mustafa; Nalbantgil, Didem
Objective: To compare the effects of low-frequency vibration (LFV), photobiomodulation (PBM), and their combination (HOT) on the rate of mandibular incisor alignment during clear aligner therapy. Methods: This retrospective study included 89 patients treated with a single clear aligner system for mild-to-moderate mandibular anterior crowding. Patients were assigned to four groups: control (n=19), LFV (n=26), PBM (n=21), and HOT (n=23). LFV [30 Hz, 0.25 N (≈25 g)] and PBM (850 nm, 16×5 mm LEDs, ≈9.5 J/cm2 ) devices were used daily for 20 minutes in relevant groups. The primary outcome was the change in Little’s Irregularity Index at baseline (T0), 28 days (T1), 48 days (T2), and 62 days (T3). Statistical analyses included one-way ANOVA, repeated measures ANOVA, and Pearson’s correlation. Results: The HOT group showed significantly greater crowding reduction compared to all other groups (p<0.05). LFV and PBM alone were not significantly different from the control. Within-group analysis revealed significant reductions in all groups over time, with the HOT group showing consistent improvements at each interval. Correlation analyses revealed no significant associations between device usage or aligner wear time and crowding reduction. Conclusion: Combining LFV and PBM during clear aligner therapy produced greater short-term acceleration of mandibular incisor alignment than either modality alone. Further randomized controlled trials are warranted to confirm long-term efficacy and safety.

(Galenos Publishing House, 2025) Oraloğlu, Göktürk; Duman, Nilay; Yaman, Banu; Akalın, Taner; Karaarslan, Işıl
Aim: Xeroderma pigmentosum (XP) is a life-threatening disease characterized by high rates of skin cancers. Therefore, it is important to establish key guidelines for the follow-up of these patients to detect skin cancers, particularly melanoma, at an early stage. Materials and Methods: This is a retrospective study that includes the analysis of the follow-up findings and medical records of XP patients who were followed up with whole-body skin examination, dermoscopic examination, and whole-body photographing between 2003 and 2021 in the Dermato Oncology unit of Ege University Department of Dermatology. Results: Of the 19 patients, 10 were male and 9 were female. The youngest patient was 5 years old, while the oldest patient was 64 years old. A total of 234 lesions were excised from these patients. Seventeen melanomas were excised, including 11 in situ, with a Breslow thickness of less than 1 mm. The highest Breslow scores belong to patients who missed their appointments or did not receive follow-up care previously. Conclusion: It was observed that regular full-body skin examinations, whole-body photography, and dermoscopic monitoring performed at 3-month intervals in XP patients are helpful in detecting skin malignancies at an early stage and preventing unnecessary excisions.

Conclusion: The study findings conclusively demonstrated the validity and reliability of the MMSS as a robust measurement tool specifically designed for assessing female individuals.
Investigating impostor syndrome among postgraduate anatomy students
(Galenos Publishing House, 2025) Ok, Fatma; Karip, Burak; Nteli Chatzioglou, Gkionoul; Temizsoy Korkmaz, Fulya; Yiğit, Mehmet
Background: Impostor syndrome (IS) is marked by persistent self-doubt and the fear of being perceived as a fraud, even in the presence of clear accomplishments, and it notably affects high-achieving individuals. This study examined IS prevalence and associated factors among postgraduate anatomy students in Türkiye. Materials and Methods: Using the Clance Impostor Phenomenon Scale, 79 participants were surveyed to assess IS levels alongside demographic and psychiatric variables. Results: The results revealed that 39.2% of participants exhibited frequent impostor feelings (FIF) or intense impostor experiences (IIE). Notably, individuals with psychiatric conditions had significantly higher IS levels, with 64.7% classified in the FIF category and 17.6% in IIE, compared to those without psychiatric issues, who predominantly fell into lower IS categories (p<0.05). No statistically significant associations were observed between IS and demographic variables, including gender, marital status, or education level. However, individuals with no income were overrepresented in the IIE category, aligning with findings from studies suggesting a link between socioeconomic status and heightened IS levels. Conclusion: This study underscores the prevalence of IS in postgraduate students within a demanding academic discipline and highlights its association with psychiatric conditions. Increasing awareness of IS, particularly in high-stress, perfectionist professions such as academia, is critical. Such efforts can improve recognition, provide targeted interventions, and mitigate IS’s impact on individual well-being and professional performance.

(Turkiye Klinikleri Yayınevi, 2025) Yıldız, Mehmet Selim; Mert Eren, Meltem; Gürcan, Aliye Tuğçe
Objective: There is lack of sufficient published data in Türkiye to describe and compare the knowledge and attitudes of students from various faculties regarding their oral healthcare. Aim of this research was to assess and compare self-reported attitudes, knowledge, and behaviors related to oral health among cohort of dentistry, medicine, and pharmacy students, with purpose of increasing awareness of oral and dental health among participants themselves and indirectly within their social circles. Material and Methods: This cross-sectional study included 354 preclinical students from the faculties of dentistry (n=127), medicine (n=113), and pharmacy (n=114). 28-question survey adapted from previous studies assessed oral health attitudes, knowledge, and behaviors. Survey was administered during scheduled class hours to ensure high response rate and consistent participation. Data were summarized using descriptive statistics, with Kolmogorov-Smirnov test applied to assess distribution, and KruskalWallis, Mann-Whitney U, chi-square tests used for group comparisons. Results: Satisfaction with teeth colour and appearance of smiles in photographs showed similar results across all groups. Female students exhibited significantly higher sensitivity towards daily brushing, flossing, and mouthwash usage, while male students were more inclined towards smoking (p<0.05). Dentistry students, in particular, demonstrated clear preference for sugarfree chewing gum. Brushing technique held greater importance for dentistry participants compared to other groups. Additionally, individuals with knowledge about interdental cleaning aids were more prevalent in dentistry group. Conclusion: The finding that awareness among dentistry students is higher than that of students from other faculties is noteworthy, as dentistry students receive coursework in the same field.

Conclusion: The presented data regarding the spinoglenoid notch in which the suprascapular nerve is frequently compressed and the branches of the suprascapular nerve to the infraspinatus muscle may guide the surgical treatment of the related entrap ment syndrome.
Early stage effectiveness of the automated insulin delivery system—is artificial intelligence really effective?
(AVES, 2025) Çetin, Ferhat; Göncüoğlu, Enver Şükrü; Abalı, Saygın; Arslanoğlu, İlknur; Deyneli, Oğuzhan; Telci Çaklılı, Özge; Yalın Turna, Hülya; Şahiner, Elif; Güzel, Dila; Yılmaz, Mehmet Temel
Objective: This study aimed to evaluate the effectiveness of the self-learning capabilities of artificial intelligence (AI) algorithms. The hypothesis was that if the success of closed-loop insulin delivery is mainly attributed to AI algorithms, then the improvement in glycemic control would be more signifi cant just after the “learning” phase. Methods: The Medtrum A8 TouchCare® Nano system was used on 15 patients with type 1 diabetes. Daily continuous glucose monitoring (CGM) data pre-automated insulin delivery (AID) was statisti cally compared with the post-AID period. Results: Patients (median age 32 (6-54) years, 40% female) had a median HbA1c of 8.4% (5.3-10.7) before initiation of AID and a median GMI of 6.6% (5.8-8.3) after 2 weeks. The shifts in glycemia and glycemic variability between the 5-day period pre-AID vs. the first day and the 3 5-day periods post-AID were significant (pre-AID vs. 1-5-10-15 days; time in range (TIR, %): 55.9 vs. 76.6-81.7-83.8- 81.5 (P=.001); Q1 (mg/dL): 123 vs. 112-108-106-110 (P=.009); Q3 (mg/dL): 204 vs. 176-173-168-169 (P=.004); inter-quarter range (IQR, mg/dL): 78 vs. 57.2-56.6-53-55 (P=.002)). The biggest shift in TIR was achieved in the first day (10.1%). Comparative analysis of the 5-day intervals post-AID was insig nificant by means of the improvement in glycemia (P > .05). No significant change in glycemic param eters between 15, 30, and 90 days were noted (P > .05). Conclusion: Artificial intelligence-augmented AID becomes effective at the very early stages of initia tion. There is a need for further research into glycemic changes in the early days of AID initiation to better define the principles of initiating AID systems.
The impact of unplanned pregnancy on prenatal attachment and subjective happiness
(Ataturk University Publications, 2025) Şahin, Ezgi; Yazıcı, Saadet; Yurtsev, Esra
Objective: Unplanned pregnancies are a major public health problem that causes undesirable socio‐ economic and psychological consequences for women, children and families in both developed and developing countries. This study was carried out to evaluate the impact of unplanned pregnancy on prenatal attachment and subjective happiness. Methods: This analytical cross‐sectional study was conducted with 342 pregnant women who attended the Obstetrics and Gynecology outpatient clinic of a university hospital between July 2022 and October 2022. Data was collected using the Demographic Information Form, London Unplanned Pregnancy Determination Scale, Prenatal Attachment Inventory, and Subjective Happiness Scale. The data was evaluated using descriptive statistics, as well as pearson correlation and regression analyses. Results: Age, number of pregnancies, pregnancy week, feelings experienced upon learning of the pregnancy, and previous pregnancy loss status all appear to have a statistically significant effect on the prenatal attachment and subjective happiness scale (p<.001). Regression analysis results show that prenatal attachment and subjective well being have a statistically significant effect on the London Unplanned Pregnancy Determination Scale (R2 =0.495). Conclusion: It has been found that unplanned pregnancies negatively affect early maternal behavior and individual happiness before birth. Therefore, it is considered important to provide counseling and psychosocial support to all pregnant women in order to bond with motherhood and ensure subjective happiness, along with prenatal education.
