Diffuse alveolar hemorrhage induced by epileptic seizure
(Wiley, 2025) Talibov, Tural; İnci, Meltem; Ismayilov, Rashad; Bebek, Nerses
Diffuse alveolar hemorrhage (DAH) is a rare but life-threatening complication of generalized tonic–clonic seizures. We describe a 28-year-old woman with no prior seizure history who experienced three consecutive generalized tonic–clonic seizures, followed by acute hemoptysis and dyspnea. Imaging confirmed diffuse alveolar hemorrhage, which responded rapidly to corticosteroid therapy. Seizure-induced DAH is an uncommon and underrecognized condition. This case underscores the importance of considering DAH in patients presenting with respiratory symptoms following seizures, even in the absence of underlying systemic disease.
Testing the performance of cross-correlation techniques to search for molecular features in JWST NIRSpec G395H observations of transiting exoplanets
(Oxford University Press, 2025) Esparza-Borges, Emma; Lopez-Morales, Mercedes; Palle, Enric; Makhnev, Vladimir; Gordon, Iouli; Hargreaves, Robert; Kirk, James; Caceres, Claudio; Solmaz, Arif; Redfield, Seth
Cross-correlations techniques offer an alternative method to search for molecular species in James Webb Space Telescope (JWST) observations of exoplanet atmospheres. In a previous article, we applied cross-correlation functions for the first time to JWST NIRSpec/G395H observations of exoplanet atmospheres, resulting in a detection of CO in the transmission spectrum of WASP-39b and a tentative detection of CO isotopologues. Here, we present an improved version of our cross-correlation technique and an investigation into how efficient the technique is when searching for other molecules in JWST NIRSpec/G395H data. Our search results in the detection of more molecules via cross-correlations in the atmosphere of WASP-39b, including H2O and CO2, and confirms the CO detection. This result proves that cross-correlations are a robust and computationally cheap alternative method to search for molecular species in transmission spectra observed with JWST. We also searched for other molecules (CH4, NH3, SO2, N2O, H2S, PH3, O3, and C2H2) that were not detected, for which we provide the definition of their cross-correlation baselines for future searches of those molecules in other targets. We find that that the cross-correlation search of each molecule is more efficient over limited wavelength regions of the spectrum, where the signal for that molecule dominates over other molecules, than over broad wavelength ranges. In general, we also find that Gaussian normalization is the most efficient normalization mode for the generation of the molecular templates.
A novel model for early prediction of in hospital mortality in seawater drowning: The SNOP score
(Springer Nature Link, 2025) Öncü, Kıvanç; Özcan, Özhan; Şi̇mşi̇rgi̇l Kara, Şeyma; Parmaksız, Ayhan; Erşen, Teoman
Background Drowning is a leading cause of preventable mortality worldwide; however, early in-hospital risk stratification remains limited. Although tools such as the Szpilman score assist in early severity assessment, they may not fully capture the evolving clinical status after admission. This study aimed to develop a simplified and objective model based on readily available parameters to predict in-hospital mortality following seawater drowning. Methods This retrospective study was conducted at a referral emergency department (ED) in northern Turkey between July 1, 2011, and December 31, 2024. Of 190 patients initially included, 166 with complete clinical and laboratory data were analyzed. Data were obtained from institutional and national health information systems. Clinical, physiological, and biochemical variables were assessed. Predictors of in-hospital mortality were identified using receiver operating characteristic (ROC) analysis and multivariable logistic regression. Variables with near-perfect discrimination (e.g., GCS, pH, Szpilman score) were excluded to avoid overfitting. Results Among the 166 patients, 34 (20.5%) died during hospitalization. CPR and endotracheal intubation rates were significantly higher among non-survivors (CPR: 97.1% vs. 0%; intubation: 97.1% vs. 2.3%; both p<0.001). Non survivors also presented with lower GCS (median 3 vs. 15), lower arterial pH, and higher Szpilman scores (all p<0.001). ROC analysis identified four potential predictors with AUC values between 0.90 and 0.95—pCO₂, lactate, SpO₂, and sodium—all showing significant discriminatory capacity (p<0.001). These variables were entered into a binary logistic regression model, from which serum sodium (OR=2.110; 95% CI: 1.310–3.401; p=0.002) and SpO₂ (OR=0.902; 95% CI: 0.847–0.961; p=0.001) emerged as independent predictors. These formed the basis of the SNOP score (Saturation and Natremia-based Outcome Predictor), a two-parameter logistic model demonstrating excellent performance: AUC=0.996, sensitivity=99.0%, specificity=96.2%, and overall accuracy=98.4%. Conclusion: The SNOP score is a simple, ED-specific tool for early prediction of in-hospital mortality in seawater drowning. It complements existing assessment systems by incorporating objective, admission-based parameters. Prospective multicenter validation is warranted to confirm its clinical applicability and support broader implementation.
PRDM6 promoter methylation as a potential epigenetic biomarker in BRCA-associated ovarian cancer
(MRE Press, 2025) Cömert, Numan; Şükrüoğlu Erdoğan, Özge; Çelik Demirbaş, Betül; Kılıç Erciyas, Seda; Dinç, Ahmet; Pasin, Özge; Yazıcı, Hülya; Tuncer, Şeref Buğra
Background: Ovarian cancer (OC) remains one of the most lethal gynecologic malignancies, primarily due to late-stage diagnosis. Aberrant DNA methylation is critical in tumorigenesis and represents a promising avenue for biomarker development. We hypothesized that PR/SET domain 6 (PRDM6) methylation is associated with breast cancer gene (BRCA) mutation status in OC. Methods: Peripheral blood samples were collected from 387 patients with high-grade serous ovarian cancer, 50 individuals with benign ovarian conditions, and 100 healthy controls. DNA methylation was evaluated using methylation-sensitive restriction enzymes (MSREs) and subsequently analyzed by real-time polymerase chain reaction (PCR). Descriptive statistics were employed to summarize categorical and continuous variables. Associations between PRDM6 methylation and clinical parameters, including BRCA mutation status, cancer antigen 125 (CA-125) levels, and age, were statistically analyzed. Results: PRDM6 methylation was detected in 53.9% of OC patients, 60.0% of individuals with benign ovarian disease, and 37.0% of healthy controls. The methylation frequency in OC patients was significantly higher than in healthy controls (p = 0.005). PRDM6 promoter methylation was detected in 64.8% of BRCA-mutated OC patients compared to 50.3% of BRCA negative patients, indicating a significant association between BRCA mutation status and PRDM6 methylation (p = 0.016). No significant associations were found between PRDM6 methylation and age, menopausal status, or CA-125 levels. Conclusions: PRDM6 methylation may serve as a non-invasive biomarker for early detection in high risk populations, particularly in BRCA mutation carriers.
Lowered phase transition temperature of VO2(m) via molybdenum doping toward efficient aqueous zinc-ion batteries
(Wiley, 2025) Aydın Şahin, Selay; Aydoğdu, Büşra; Yaman Uzunoğlu, Gülşah; Yüksel, Recep
Rechargeable aqueous zinc-ion batteries have attracted considerable attention as large-scale energy storage systems owing to their safety, sustainability, and cost-effectiveness. However, their practical application has been hindered by limited energy density, primarily determined by cathode performance. Among transition metal oxides, vanadium dioxide (VO2) is particularly appealing due to its layered structure, rich polymorphism, and ability to host Zn2+ ions reversibly. The thermally driven transition from insulating VO2(M) to conductive VO2(R) enhances charge transport through the metal–insulator transition (MIT). In this work, molybdenum doping is employed to lower the MIT temperature of VO2(M). Doping reduces the MIT temperature of the VO2(M) phase to 56.7 °C, resulting in the VO2(R) phase. Electrochemical measurements reveal that Mo-VO2(R) cathodes deliver up to ten times higher capacity than the pristine VO2(M), with 3Mo-VO2(R) reaching 404.8 mAh g–1 at 0.1 A g–1. These findings demonstrate that Mo doping serves as a practical approach to modify VO2(M) and decrease the MIT temperature, while improving electrochemical performance. Moreover, the heteroatom doping strategy suggests a promising pathway for developing other VO2 cathodes for efficient rechargeable batteries, which can leverage the heat dissipated in energy storage systems.
Polyherbal ointment with bromelain for chronic diabetic wounds: Insights from a clinical case series
(Springer Nature Link, 2025) Bostanabad, Saber Yari; Özdemir, Samet; Saadati, Mahrokh; Karaca, Banu; Şener, Alper
Purpose Chronic diabetic wounds are characterized by prolonged inflammation and impaired healing. This study evaluates a novel polyherbal ointment, W Cura D Plus®, which contains Azadirachta indica oil, Hypericum perforatum oil, and bro melain from Ananas comosus. After initial debridement with W Cura D Plus®, treatment continued with W Cura G Plus®. To our knowledge, this is the first clinical report examining this specific combination in the treatment of chronic diabetic wounds. Methods A single-center clinical case series was conducted in 13 diabetic patients with Wagner grade 2–3 diabetic foot ulcers of at least 4 weeks’ duration. All patients were on standard type 2 diabetes therapy (oral agents and/or insulin) and routine wound care prior to enrollment. W Cura D Plus® was applied daily for 7 days to promote debridement, followed by W Cura G Plus® until complete closure or no further reduction in ulcer size for two consecutive weeks. Clinical endpoints included wound area, closure percentage, and recovery time. White blood cell (WBC) and C-reactive protein (CRP) levels were monitored. Results Fourteen wound observations were analyzed. Mean wound area decreased from 25.07±24.56 cm² at baseline to 7.38±5.15 cm² (p=0.0103), and mean closure rate was 64.15±0.23% (p=0.0108), surpassing the 50% benchmark for clini cally meaningful improvement. Recovery time averaged 97.7 days compared to baseline (initial status prior to treatment). WBC and CRP significantly declined (p<0.0001). No adverse events were reported. Conclusion This polyherbal formulation may represent a safe adjunct to standard care, but larger controlled trials are needed to confirm efficacy.
Unveiling the interplay of EBV, HSV-1, and ınflammatory biomarkers in psychiatric disorders
(MDPI Publishing, 2025) Akgül, Özer; Demirel, Ömer Faruk; Tosun, İlker; Kavla, Yasin; Kırkpınar, Mehmet Murat; Sapmaz, Burcu; Şenyiğit, Gülçin; Çalışkan, Reyhan; Öner, Yaşar Ali
Background/Objectives: Schizophrenia (SCH), bipolar disorder (BPD), and major depres sive disorder (MDD) are increasingly viewed as neuroimmune disorders shaped by viral exposure and inflammation. Disorder-specific immunovirological profiles, however, re main poorly defined. Methods: In this cross-sectional study, we assessed Epstein–Barr Virus (EBV) and Herpes Simplex Virus type 1 (HSV-1) seropositivity and measured serum CRP, IL-6, and IL-1β in 708 participants: 110 with SCH, 121 with BPD, 135 with MDD, and 342 healthy controls (HC). Statistical analyses included Shapiro–Wilk tests for nor mality; Kruskal–Wallis with Bonferroni-adjusted Dunn post hoc comparisons; and logistic regression adjusted for age, sex, and marital status. Results: EBV seropositivity was higher in SCH (90.9%) than in HC (78.9%) (OR = 3.46, 95% CI: 1.68–7.12; p = 0.001) but not in BPD or MDD. HSV-1 seropositivity was elevated in BPD (83.5%) versus HC (67.0%) (OR = 2.29, 95% CI: 1.34–3.92; p = 0.003), with no differences in SCH or MDD. Inflammatory biomarkers were significantly increased in SCH and MDD compared to HC (p < 0.001), while BPD showed no differences. Conclusions: The findings delineate distinct immunovi rological patterns across major psychiatric disorders. Schizophrenia was characterized by EBV seropositivity accompanied by systemic inflammatory activation, bipolar disorder by HSV-1 seropositivity in the absence of inflammatory changes, and major depressive disor der by inflammatory dysregulation independent of viral exposure. These disorder-specific profiles highlight heterogeneity in neuroimmune pathways and underscore the potential relevance of biomarker-based stratification for generating hypotheses regarding targeted antiviral or anti-inflammatory interventions in psychiatric populations.
Visual quality assessment of E-commerce product images using convolutional neural networks
(Springer Nature Link, 2025) Tbaileh, Imad; Bağrıyanık, Selami
High-quality product images are vital in shaping consumer trust and driving engagement on e-commerce platforms. This study proposes a deep learning-based approach for evaluating the visual quality of product images, with the aim of improving the overall customer experience and presentation standards in online marketplaces. A custom-labeled dataset was developed, containing thousands of product images categorized into five quality levels. A convolutional neural net work (CNN) was trained to classify these images based on their visual quality. In addition, two well-known architectures, MobileNetV2 and EfficientNetB0, were trained under identical conditions to serve as benchmarks for performance com parison. The proposed CNN model achieved an accuracy of 94.93%, outperforming both MobileNetV2 (76.60%) and EfficientNetB0 (92.77%). It also delivered the highest performance in terms of precision, recall, and F1-score, confirming its effectiveness in this domain. The results highlight the CNN model’s suitability for real-time quality assessment of e-commerce images. Its strong performance and efficiency make it a promising candidate for integration into commercial platforms. Future work will investigate the use of transformer-based models and more diverse training data to further improve accuracy and generalizability.
Branching patterns and variations of the anterior choroidal artery: A detailed cadaveric morphometric analysis
(Springer Nature Link, 2025) Kaçur, İdil; Nteli Chatzioglou, Gkionoul; Nas, Emine; Gayretli, Özcan
The aim of our study was to investigate the morphometric and morphological characteristics of the anterior choroidal artery (AChA) and its branches. Also, the branching patterns and cortical termination sites of the AChA were examined by detailed morphometric analysis. For this purpose, 62 fresh cadavers (124 hemispheres) were included in the study. AChA diameter, length, and distances of branches to the AChA origin were measured using ImageJ software. The distribution of the branches according to arterial origin and their distances to the target regions was quantitatively defined. Although a total of 594 branches originating from AchA were observed, only 587 of these branches reached or terminated in the regions observed. Accordingly, 220/587 were found to go to the optic tract, 214/587 to the cerebral peduncle, 130/587 to the uncus, and 23/587 to the anterior perforated substance. Our study provides novel morphometric ratios that map the branching architecture of the AChA, confirming that branches originate predominantly from its midpoint (overall ratio:0.45). We found that 73.07% of AChA branches supply the optic tract and cerebral peduncle, highlighting their central role, while a minimal proportion (3.87%) serve the anterior perforated substance. These data elucidate the topo graphical relationships that are crucial for understanding pathologies like Moyamoya disease and proximal aneurysms. The established ratios offer invaluable benchmarks for anatomical navigation, potentially reducing risks in neurosurgical procedures involving the AChA territory.

(Oxford University Press, 2025) Ağlamış, Savaş Özgür; Akkaya, Selver Kübra; Şahin, Elif; Şahin, Hanifi
Background: Polydioxanone (PDO) thread is a synthetic absorbable surgical suture used for rejuvenation and lifting. Aim: The aim of this study is to use PDO threads for rejuvenation and enlargement effect in patients with labium majus hypotrophy. Methods: Twenty-one patients with labia majora hypotrophy were included in the study. Conventionally, surgery, fat filling or hyaluronic acid filling is used for labia majora rejuvenation. In this study, a different technique, the PDO thread suspension technique, was applied. For PDO thread, Hyundae Meditech Co.Ltd’s Secret Line Up product containing 50 mm screw thread with 30 G-38 mm needle tip was used. It was planned to use 10 PDO threads for right and left labia majora. After a total of 20 needles were inserted, the needles were removed one by one and the PDO threads remained in the subcutaneous superficial layer and the procedure was terminated 5 min later. Preoperative and postoperative the Female Genital Self-Image Scale (FGSIS) scores of the patients were compared. Outcomes: The overall FGSIS total score demonstrated a significant increase following the intervention. Results: The FGSIS total mean score in the preoperative period was increased in the postoperative period. This difference was statistically significant. Moreover, the mean score calculated for each parameter of FGSIS in the preoperative period increased significantly in the postoperative period. Clinical Implications: These findings indicate a favorable safety profile for the use of PDO threads in this clinical context. Strengths and Limitations: The strength of the study is to introduce a minimally invasive and effective method for labia majora lifting, on the other hand, the small number of patients in the study, limitation of the study. Conclusion: We would like to point out that in this study, we evaluated labium majus rejuvenation from the same perspective, based on the shaping and enlargement of genital appearance and its positive effect on self-confidence and increase in sexual functions. Unlike many labium majus rejuvenation procedures, this less invasive procedure has achieved similar results. In this context, it is a preferable alternative to surgery.

Improving oral health in children with disabilities: A preventive home-based care model from Türkiye
(Wiley, 2025) Tunalı, Esra; Ataş, Cafer; Çağ, Yakup; Orhan, Ahmet Lütfullah; Özen, Buğra; Aydınbelge, Mustafa; Tunalı, Mustafa
Background: Children with Special Health Care Needs (CSHCN) face significant challenges in maintaining oral hygiene and accessing dental services due to disabilities. It has been reported that, because of these disadvantages, individuals with special needs experience oral health problems at a higher rate compared to the general population. This study aimed to assess factors influencing oral health in CSHCN within the dental home framework and propose preventive strategies. Methods: A total of 1229 children aged 0-8 years with disability health reports in Istanbul were examined through home visits by mobile dental teams. Caries experience was evaluated using combined indices (dfs + DMFS and dft + DMFT). Data on oral hygiene habits, dietary patterns, parental education level and dental visit history were collected through structured questionnaires. Statistical analyses included Mann-Whitney U, Kruskal-Wallis, chi-square and Spearman's correlation tests (significance set at p < 0.05). Results: A statistically significant positive correlation was found between age and all caries indices (p < 0.01) 0.57. 1% of children reported brushing their teeth, with irregular brushers showing significantly higher caries indices than regular brushers (p < 0.05). Children requiring > 45 min to eat had significantly higher dfs + DMFS (1 surface) (p = 0.036) and dft + DMFT values (p = 0.019). Those consuming snacks > 3 times daily showed significantly higher caries indices across all measures (p < 0.01). Moderate/severe plaque accumulation was detected in 50.5% of participants. Lower parental education levels were significantly associated with higher caries indices (p < 0.01). Conclusions: This study highlights the necessity of an interdisciplinary approach to protect the oral health of CSHCN. The widespread implementation of the dental home model and regular dental check-ups will be a significant step in addressing oral health needs.
Effect of magnification and press-on force on resin composite polishing
(BioMed Central, 2025) Ünal, Tuna; Korkut, Bora; Tağtekin, Dilek
Objective To evaluate surface roughness (Ra) and gloss (GU) of two resin composites after polishing with two systems, using a novel press-on force guided (PFG) polishing simulator. Materials and methods Eighty specimens were prepared using Essentia Universal (EU) and G-aenial Universal Injectable (GUI) composites. Surface roughness and gloss were assessed by a profilometer (Marsurf Ps10), and a glossmeter (Novo-Curve). They were polished with Sof-Lex and Twist Dia systems with or without magnification and PFG. Each polishing material was used for 30 s. Ra1 and GU1 measurements were repeated by the same operator. Data were analyzed using One-way ANOVA, Three-way ANOVA, and Robust ANOVA with Bonferroni Correction for multiple comparisons and Spearman’s rho Correlation Coefficient (<0.050). Results Higher Ra values were observed in GUI group for Twist Dia (0.33±0.05z ) compared to SofLex (0.22±0.08y ). Roughness was higher when PFG was uncontrolled (0.31±0.07x ), compared to the controlled (0.25±0.09w). No Ra difference was observed in EU group between SofLex (0.33±0.04) and Twist Dia (0.29±0.04)(P=.440). Uncontrolled PFG provided higher gloss for GUI and EU composites (69.7±2.91x , 54.63±18.68x , respectively). Twist Dia presented higher gloss for GUI and EU composites (72.3±2.57z ,58.88±13.73z , respectively). Magnification did not affect the roughness or gloss for both composites (P≥.05). A moderate negative correlation was found between roughness and gloss in GUI (r=-.546)(P<.001), while no correlation was observed in EU (r=-.110)(P=.449). Conclusion Higher surface roughness and gloss were observed with uncontrolled (not constant) press-on force. Even though SofLex may provide a lower surface roughness, Twist Dia can generate a greater surface gloss regardless of the composite type. 3.5X loupe magnification was not effective on surface roughness and gloss within a limited polishing time. Clinical Relevance Press-on force is an important factor affecting the composite polishing quality. Spiral polishing wheels can be advantageous for composite restoration polishing, as they better preserve the secondary and tertiary anatomies and provide a higher gloss. The effect of magnification on composite polishing can be related to the time spent using it.
