    Alignment of integrated management systems with modern management trends: A fact-based review
    (Gheorghe Asachi Technical University of Iasi, Romania, 2025) Ergat, Zeynep; Kalender, Zeynep Tuğçe; Vayvay, Özalp
    In today's dynamic business environment, organizations are increasingly adopting Integrated Management Systems to streamline their operations and enhance performance across various domains. However, implementing Integrated Management Systems is challenging due to the complexity of integrating various management systems and overcoming cultural resistance within organizations. Additionally, limited understanding of how Integrated Management Systems align with emerging trends such as lean management, sustainability and agile management, hindering organizations' ability to leverage integrated systems to effectively navigate complexities and capitalize on opportunities in the rapidly evolving business landscape. This study synthesizes existing research to examine how Integrated Management Systems can be improved with alignment of the modern management trends by analysing the literature. In this review, the relationship between IMS and sustainability, the impact and contribution of agile and lean management on the environmental, social and economic dimensions of sustainability were determined. The findingsunderscore that while Integrated Management Systems implementation enhances efficiency, its success hinges on overcoming integration complexities and cultural resistance. This review reveals that aligning it with contemporary management trends notonly supports continuous improvement but also strengthens environmental, social, and economic sustainability. Key insights emphasize the importance of agility and risk anticipation, as well as the critical role of human and cultural factors in every process. These findings offer valuable implications for both theory and practice, providing a foundation for future research to foster resilience and adaptability in today's dynamic business environment.

    Role of S100B, neuron-specific enolase, and adrenomedullin in differentiating central and peripheral vertigo
    (Bayrakol Medical Publisher, 2026) Onur, Bahaeddin; Özdemir, Serdar; Koçak, Mehmet; Ünal Akoğlu, Ebru; Demir, Hasan; Cimilli Öztürk, Tuba; Onur, Özge Ecmel
    Aim: This study aimed to evaluate S100B, adrenomedullin (ADM), and neuron-specific enolase (NSE) as diagnostic biomarkers to differentiate central and peripheral vertigo in patients with dizziness. Methods: A prospective cohort study was conducted with 88 patients (58% women) presenting with dizziness. Patients were categorized based on MRI findings into two groups: those with acute lesions (central vertigo) and those without lesions (peripheral vertigo). S100B, ADM, and NSE levels were measured and compared between the groups to assess their diagnostic value for central vertigo. Results: Significant differences were found in S100B, NSE, and ADM levels between the central and peripheral vertigo groups (p=0.003, 0.008, and 0.010, respectively). Factors predicting MRI-detected lesions included age, mean arterial pressure, movement-induced and positional vertigo, neurological findings, history of hypertension, lack of response to symptomatic treatment, and elevated S100B, ADM, and NSE levels. Logistic regression analysis identified the lack of response to symptomatic treatment as the only significant predictor (p=0.0148). Conclusion: S100B, ADM, and NSE levels significantly differ between central and peripheral vertigo, suggesting their potential as diagnostic biomarkers. However, only the lack of response to symptomatic treatment was a significant predictor. Further research is needed to validate these biomarkers alongside clinical assessments and imaging.

    Suboptimal LDL-cholesterol control under the 2019 ESC/EAS dyslipidemia guidelines: Results from the nationwide TEMD-2 study in type 2 diabetes
    (Wiley, 2026) Telci Çaklılı, Özge; Haymana, Cem; Demirci, İbrahim; Kebapçı, Medine Nur; Sarıakçalı, Barış; Evren, Bahri; Dizdar, Oğuzhan Sıtkı; Salman, Serpil; Ersoy, Canan; Satman, İlhan; Bayram, Fahri; Sönmez, Alper
    Background: Lowering LDL cholesterol (LDL-C) decreases cardiovascular risk substantially in type 2 diabetes. Despite stricter LDL-cholesterol targets in the 2019 ESC/EAS dyslipidemia guidelines, target achievement in clinical practice remains insuffi cient. TEMD-2 is designed to evaluate LDL-cholesterol target attainment in Turkish patients with type 2 diabetes in the context of the updated 2019 ESC/EAS guidelines. Methods: This multicenter cross-sectional study included adults with type 2 diabetes followed in 70 tertiary endocrine clinics across 36 cities between October 2022 and January 2023. Sociodemographic characteristics, comorbidities, lifestyle factors, com plications, laboratory measurements, and lipid-lowering therapies were assessed using standardized questionnaires and clinical evaluations. LDL-C target was assigned according to cardiovascular risk categories. Independent predictors of goal attainment were identified using multivariable logistic regression. Results: Among 4956 adults with type 2 diabetes, 99.5% required statin therapy, whereas 37.1% were on treatment. Overall, 8.3% of the cohort achieved LDL-cholesterol targets, with attainment lowest in those at very high risk (5.8%). Target achievement among statin users was 57.7% in moderate-risk, 18.1% in high-risk, and 9.4% in very-high-risk patients. Individuals on target had lower body mass index, haemoglobin A1c (HbA1c), triglycerides, and a lower prevalence of microvascular complications. Statin therapy was the strongest positive predictor of success (odds ratio 2.39), while smoking, presence of neuropathy, nephropathy, female sex, older age, and higher HbA1c were associated with lower likelihood of achieving LDL-cholesterol goals. Therapeutic inertia was present in 87.2% of patients, defined as no intensification of lipid-lowering therapy despite LDL-cholesterol levels above target.

    Green MIP-based electrochemical sensing platform for environmental ivermectin analysis
    (American Chemical Society, 2026) Aydemir, Zeynep; Kaya, Beril Sena; Dorreh, Setareh; Al Faysal, Abdullah; Erdoğan, Taner; Gölcü, Ayşegül
    Ivermectin (IVM), a macrocyclic lactone derived from Streptomyces avermitilis, is widely recognized as a “wonder drug” for its broad-spectrum efficacy against internal and external parasites in human and veterinary medicine. Owing to its potent pharmacological activity, precise quantification of IVM is essential for therapeutic monitoring and dose optimization. In this study, we report the design of a novel electrochemical sensor based on molecularly imprinted polymer (MIP) technology, specifically tailored for the selective detection of IVM. The sensor was fabricated via an electropolymerization strategy employing methacrylic acid (MAA) as the functional monomer and aniline as the comonomer in phosphate-buffered saline (PBS, pH 7.0). To the best of our knowledge, this represents the first electropolymerization-based MIP sensor developed for IVM determination. The resulting MAA-IVM@MIP/GCE sensor was thoroughly characterized using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). Electrochemical detection was achieved through an indirect redox probe approach with 5.0 mM [Fe(CN)6] 3−/4−, providing a wide linear range (1 × 10−12 −1 × 10−11 M) and remarkably low limits of detection (LOD: 2.91 × 10−13 M) and quantification (LOQ: 9.71 × 10−13 M). The sensor demonstrated high sensitivity, reproducibility, and selectivity, clearly distinguishing IVM from structurally related compounds. It maintained strong analytical performance in pharmaceutical formulations, biological matrices, and environmental samples such as tap water and soil, showing minimal matrix interference. These results confirm the platform’s robustness and applicability. Density functional theory (DFT) calculations were performed to evaluate template−monomer interactions and determine the optimal template:monomer ratio for the MIP-based sensor. The results revealed that the 1:1 complex exhibited the most favorable binding characteristics, consistent with the experimental findings. In addition, the sensor fabrication strategy was designed in accordance with green analytical chemistry principles. The electropolymerization process was performed in aqueous phosphate-buffered saline under mild conditions without the use of excessive cross-linkers or hazardous reagents. The approach minimizes organic solvent consumption, reduces energy requirements, and enables sensor reusability, thereby contributing to a sustainable and environmentally responsible analytical platform. Overall, this cost-effective, scalable, and environmentally conscious electrochemical sensor provides a practical tool for reliable IVM monitoring and has strong potential for clinical diagnostics, pharmacokinetics, and pharmaceutical quality control.

    Multi-target neuroprotective compound exhibits EAAT2-modulating and alzheimer’s pathology–attenuating effects in in vitro and in vivo models
    (American Chemical Society, 2026) Hacımüftüoğlu, Ahmet; Saraçoğlu, Nurullah; Saffour, Sana; Abad, Nadeem; Kesgun, Yunus; Zegheb, Nadjiba; Gündeğer, Ersin; Yeşilyurt, Fatma; Ataş, Merve Nur; Türkez, Hasan
    Alzheimer’s disease (AD) is a debilitating neuro degenerative disorder characterized by cognitive decline and memory loss. Current treatments offer limited efficacy, necessitat ing the development of innovative multitarget therapeutic strategies. Here, we present N3 ,N5 -bis(2-(5-methoxy-1H-indol-3- yl)ethyl)-2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxa mide (HCM-01), a novel compound developed to target multiple neurodegenerative pathways implicated in AD. In vitro assays included MTT-based cell viability analyses performed in two complementary experimental settings: primary neuronal cultures and astrocyte-based in vitro cell culture models exposed to glutamate. In primary hippocampal neuronal cultures, glutamate exposure induced a statistically significant reduction in cell viability compared with vehicle-treated controls, consistent with glutamate-induced excitotoxicity. Under these conditions, HCM-01 treatment resulted in a statistically significant improvement in neuronal viability, showing a greater protective effect compared with donepezil and memantine. In contrast, in astrocyte-based in vitro cultures, the applied glutamate concentration did not induce overt cytotoxicity, in line with the intrinsic neuroprotective and glutamate-buffering role of astrocytes. Accordingly, astrocytic experiments were designed to assess functional modulation of glutamate-handling mechanisms rather than cell survival. Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups, suggesting modulation of astrocyte-mediated glutamate homeostasis. In parallel, redox analyses revealed that HCM-01 improved oxidative/antioxidative balance, as evidenced by increased total antioxidant capacity (TAC) and reduced total oxidant status (TOS), supporting an indirect antioxidant contribution to its functional effects. In vivo behavioral assessment of HCM-01 in a streptozotocin (STZ)-induced Alzheimer’s model in female Sprague−Dawley rats demonstrated that administration of HCM-01 at doses of 50 mg/kg orally (oral, P.O. and intraperitoneal, I.P.) and 100 mg/kg (P.O.), significantly improved cognitive and memory functions in the passive avoidance (PA), Morris water maze (MWM), and locomotor activity tests. Moreover, histopathological and immunohistochemical analyses of different hippocampal regions revealed reduced neuronal damage, attenuation of tau pathology, antiamyloidogenic effect, and restoration of cholinergic function. Complementary in silico studies, including molecular docking, molecular dynamics simulations (MDS), and free energy calculations, suggested potential interactions of HCM-01 with the allosteric site of EAAT2. Taken together, these findings suggest that HCM-01 exerts neuroprotective effects against glutamate-induced excitotoxicity in primary hippocampal neurons while additionally modulating glutamatergic homeostasis and redox balance through functional mechanisms in astrocyte-based models, supporting its relevance as a multitarget preclinical candidate for early stage AD mechanisms.

    Ibuprofen and nimesulide derivatives selectively induce apoptosis in HER2-positive breast cancer via inhibition of the PLA₂–COX-2–NF-κB pathway
    (Springer Nature Link, 2026) Çakırlı, Egemen; Bedir, İpek; Biliz, Yağmur; Yılmaz, Özgür; Küçükgüzel, Şükriye Güniz; Telci, Dilek
    Background Chronic inflammation contributes to breast cancer development through the phospholipase A₂ (PLA₂)–cyclo oxygenase-2 (COX-2)–nuclear factor κB (NF-κB) cascade, which regulates prostaglandin synthesis, oxidative stress, and transcription of pro-inflammatory and anti-apoptotic genes. This pathway is particularly active in HER2-positive breast can cer, promoting proliferation, invasion, and resistance to apoptosis. Non-steroidal anti-inflammatory drugs such as ibuprofen and nimesulide target COX enzymes and have shown potential in suppressing inflammation-driven tumorigenesis. In this study, we evaluated the anticancer and anti-inflammatory activity of newly synthesized, structurally modified ibuprofen and nimesulide derivatives designed to modulate PLA₂–COX-2–NF-κB axis. Methods and Results Cytotoxicity was assessed in HER2-positive breast cancer cells (AU565 and SKBR3) and compared with normal dermal fibroblasts (HDF) and breast epithelial cells (MCF-12A), using WST-1 assays. Apoptosis, cell cycle distribution, caspase-3/7 activation, and ROS generation were analyzed by imaging-based assays, flow cytometry, and fluo rescence methods. Gene expression of PLA2G2A and PTGS2 was quantified by qRT-PCR, and NF-κB translocation was analyzed by immunocytochemistry. Two ibuprofen triazole derivative (D1) and ibuprofen thioether derivative (D7) and one nimesulide derivative (D8) significantly reduced cell viability in a dose-dependent manner without affecting normal cells. These derivatives induced G₀/G₁ arrest, caspase-3/7 activation, ROS reduction, and increased late apoptosis. Downregula tion of PLA2G2A and PTGS2 expression and inhibition of NF-κB translocation confirmed disruption of the PLA₂–COX-2– NF-κB cascade. Conclusion These findings demonstrate that structurally optimized ibuprofen and nimesulide derivatives exert dual anti inflammatory and anticancer effects in HER2-positive breast cancer by suppressing PLA₂–COX-2–NF-κB pathway and promoting apoptotic cell death.

    Impression precision after hydrogen peroxide sterilization of scanner sleeves
    (Springer Nature Link, 2026) Yılmaz, Berza; Arslan, Meriç; Kayasaroğlu, Damla Nur; Arslan, Elif Dilara; Sunal Aktürk, Ezgi
    Introduction The iTero Element (Align Technologies, San Jose, CA, USA) is a widely used intraoral scanning device, and its protective sleeves for the scanning head are provided for single use. This condition puts the clinical management budget under financial strain and creates a disadvantage for managing environmental waste. The objective of our research was to assess how repeated sterilization of disposable scan head covers with hydrogen peroxide affected the precision of digital impressions. Methods Intraoral scans were carried out using the iTero Element 5D scanner on 26 patients. Hydrogen peroxide was used to sterilize the sleeves for 45min at 45 °C. The sterilization procedure was repeated between the second, third, and fourth intraoral scans. Each tooth was given a score based on the color change between the first and fourth scans, which were superimposed using the iTero TimeLapse technology. The OrthoCAD® software (Align Technologies) was also used to measure the intercanine, interpremolar, and intermolar distances, as well as the mesiodistal dimensions of all the teeth between the first molars. Results No statistically significant difference was found between the mesiodistal dimensions of the teeth and the interca nine, interpremolar, and intermolar distances between the 1st and 4th scans. There was no correlation between the mean differences of the mesiodistal dimensions of the teeth obtained with the 1st and 4th scans and TimeLapse scores. Conclusion After sterilization with hydrogen peroxide, the repeatability of digital measurements of the protective sleeves of the intraoral scanner was not adversely affected, and their clinical performance was maintained.

    Ketamine induces apoptosis and inhibits proliferation in HT-29 colorectal cancer cells
    (MDPI Publishing, 2026) Korkmaz, Irmak Fatoş; Elgün, Tuğba; Aktaş, Çiğdem; Gündeğer, Ersin; Gök Yurttaş, Asiye
    Background: Colorectal cancer (CRC) is one of the most prevalent malignancies worldwide and remains a major health concern due to its high recurrence and mortality rates. Recent studies suggest that anesthetic agents, including ketamine, may have direct effects on cancer cell viability and apoptosis. Objective: This study aimed to investigate the in vitro effects of ketamine on the HT-29 human colorectal adenocarcinoma cell line, focusing on its cytotoxic and pro-apoptotic potential. Material and Methods: HT-29 cells were treated with ketamine for 24 h. Cell viability was evaluated using the MTT assay. Apoptosis rates were determined by flow cytometry with Annexin V-FITC/7-AAD staining. Furthermore, quantitative PCR (qPCR) was performed to assess the expression levels of key genes associated with proliferation and apoptosis. GeneQuery™ Human Basal Cell Carcinoma qPCR Array Kit (GQH-BCC-GK015-C) was used for qPCR analysıs. Molecular docking simulations were performed to investigate the potential molecular interactions between ketamine and three target proteins: the N-methyl-D-aspartate (NMDA) receptor, epidermal growth factor receptor (EGFR), and casein kinase 1 delta (CSNK1D). To ensure robustness of predictions, two independent docking methods were employed. Results: Ketamine significantly reduced cell viability in a dose-dependent manner, with an IC50 value of approximately 1.05 µM. Flow cytometry analysis demonstrated a marked increase in early apoptosis (23.9%) in treated cells. These findings suggest that ketamine exhibits potential anti-proliferative and pro-apoptotic effects on HT-29 colorectal cancer cells. Conclusions: These findings suggest that ketamine exhibits potential anti-proliferative and pro-apoptotic effects on HT-29 colorectal cancer cells in vitro. Further studies are warranted to elucidate the underlying molecular mechanisms and potential clinical implications.

    Sustainable synthesis of ZnO nanoparticles from melon (cucumis melo l.) by-products: RSM optimization, structural characterization, antioxidant activity, and photocatalytic performance
    (Wiley, 2026) Bozkurt, Rabia Nur; Kaba, İbrahim; Kahraman, Yusuf Sezai; Altınkeser, Tuğçe
    This study explores the eco-friendly synthesis of zinc oxide nanoparticles (ZnO-NPs) using polyphenol-rich extracts from melon (Cucumis melo L.) peel and seeds as naturalreducing and stabilizing agents. Optimization via response surface methodology (RSM) determined the ideal synthesis conditions at a 0.078 mol/L metal concentration, 14.73 mL extract, and pH 10.77. Characterization through XRD confirmed a hexagonal wurtzite crystal structure with an average size of 21.7 nm, while SEM and TEM imaging revealed predominantly spherical morphologies. UV–visible DRS analysis showed a 368 nm absorption edge with a calculated band gap of 3.21 eV. DLS measurements indicated a hydrodynamic diameter of 135.6 nm with a PDI of 0.206 and a zeta potential of −20.5 mV, confirming good colloidal stability. The resulting NPs exhibited strong antioxidant activity (IC50 = 40.7 µg/mL) and acted as effective heterogeneous photocatalysts for the degradation of organic dyes. Specifically, ZnO-NPs enabled the photodegradation of methyl orange (MO) and methylene blue (MB), achieving 63.56% degradation for 5 mg L−1 MO. These findings demonstrate that melon-waste-derived ZnO-NPs are sustainable and promising candidates for wastewater treatment and environmental remediation.

    Sun-macerated hypericum perforatum oleates in fixed oils: Analytical characterization and comparative wound-healing activity
    (The Scientific and Technological Research Council of Türkiye (TÜBİTAK), 2026) Çapar, Cihan; Küpeli, Esra; Yaba, Aylin; Parmaksız, Ayhan; Sümer, Engin; Yeşilada, Erdem
    Background/aim: Hypericum perforatum L. oleates prepared in fixed oils have long been used for wound management due to their antiinflammatory, antibacterial, and tissue-regenerative properties. The bioactivity of these oleates is mainly attributed to hypericin, hyperforin, and pseudohypericin. In the present study, the wound-healing potential of H. perforatum oleates prepared in different fixed oils, including Olea europaea L. (olive), Sesamum indicum L. (sesame), Helianthus annuus L. (sunflower), and Nigella sativa L. (black seed), is compared. Materials and methods: Fixed oils were characterized by gas chromatography–mass spectrometry, while oleuropein (olive oil) and thymoquinone (black seed oil) were quantified by high-performance liquid chromatography, and sesamin and sesamol (sesame oil) by spectrophotometry. Oleates were prepared using the traditional sun maceration method. Hypericin, hyperforin, and pseudohypericin were quantified by liquid chromatography–mass spectrometry and ultraviolet spectrophotometry. In vitro and in vivo assays were performed to assess the wound-healing activities of both the fixed oils and their respective oleates. Results: All oleates exhibited significantly greater wound-healing activity than the corresponding fixed oils. The most pronounced synergistic effects were observed with the olive oil and sesame oil oleates. Conclusion: Maceration of H. perforatum in fixed oils enhances the intrinsic therapeutic properties of oils and contributes to improvements in multiple wound-healing parameters. The findings of the present study support the traditional use of H. perforatum oleates and provide a scientific basis for their pharmacological development.

    Protective roles of gallic acid and lycopene against 4-nonylphenol induced testicular damage in SD rats
    (SAGE Publications, 2026) Güleş, Özay; Kum, Şadiye; Naseer, Zahid; Boyacıoğlu, Murat; Özel Armutoğlu, Emine; Yıldız, Mustafa; Kırıkkulak, Murat; Doğan, Göksel; Bilici, Esra; Türkmen, Aybike; Tuna, Bilginer; Eren, Ülker
    4-Nonylphenol (4-NP), an endocrine disruptor, is known to induce mutagenic, toxic, or carcinogenic effects, including testicular toxicity via inducing oxidative stress and apoptosis. The objective of this work was to determine the capacity of lycopene (LC) and gallic acid (GA) to protect testicular histological structure, biochemical responses, and semen parameters in rats exposed to 4-NP. In this 28-day dietary trial, six groups (n= 6 per group) received treatment via oral gavage: a control (corn oil, 2 mL/kg/day), LC (10 mg/kg body weight (BW)/day), GA (50 mg/kg BW/day), 4-NP (125 mg/kg BW/day), LC + 4-NP (LC followed by 4-NP), and GA + 4-NP (GA followed by 4-NP) groups. The results indicated that 4-NP administration adversely affects the final body weight, testicular histology, seminiferous epithelium heights (SEHs) (4-NP: 57.95 ± 0.49, p: 0.000), follicle-stimulating hormone (FSH) level, testis antioxidant capacity, testis malondialdehyde (MDA) level, and sperm viability and morphology. LC and GA supplementation significantly improved SEHs, activities of testis superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), and sperm viability compared to the 4-NP group. Moreover, LC and GA exposures decreased histopathological lesions, including germinal epithelial degeneration, vacuolization, immature germ cells in the tubular lumen, and congestion in the interstitial area. Furthermore, they lowered TUNEL-positive cell counts and tubule percentages, testicular MDA levels, and abnormal sperm percentages. To our knowledge, this study provides one of the first systematic comparisons of lycopene and gallic acid in protecting against 4-NP-induced testicular toxicity under identical experimental conditions. The findings suggest that both compounds preserve testicular structure and function through their antioxidant and anti-apoptotic properties.

    Efficacy-oriented approach for medium-sized follicles: A perspective on stimulation, expectation, and triggering strategy in IVF cycles
    (Wiley, 2026) Aydın, Gerçek; Ergin, Elif; Araç, Merve; Bülbül, Mehmet; Çalışkan, Eray; Hatırnaz, Şafak; Dahan, Michael; Malvasi, Antonio; Tinelli, Andrea
    Objective: To assess the therapeutic significance of routinely aspirating mid-sized fol licles (14.0–16.9 mm) during oocyte pick-up (OPU) by looking at procedural efficiency and embryo usage in cycles with varied follicular cohorts. Methods: In vitro fertilization (IVF) cycles with follicles classified as large (≥17 mm) or mid-sized (14.0–16.9 mm) at the time of OPU were included in this prospective cohort. Each group's oocytes were extracted and treated independently while main taining rigorous traceability. Analysis was performed on embryologic results, opera tive time factors, and embryo transfer utilization across successive transfer attempts. Pregnancy outcomes and the length of the operation were investigated. Laboratory results pertaining to trigger strategies were assessed descriptively. Results: When measured per mature oocyte, oocytes from mid-sized follicles showed comparable fertilization and blastocyst development rates. However, only a small percentage of embryo transfers included embryos from mid-sized follicles, especially in the initial two transfer attempts. Large follicles had a longer total OPU duration, and cycles that resulted in miscarriage had significantly longer operative times among large-follicle-derived embryo transfers. For mid-sized follicles, there were no differ ences in the length of the procedure based on the pregnancy outcome. Conclusion: The contribution of mid-sized follicle-derived oocytes to embryo trans fer selection seems to be restricted in everyday practice, despite their reassuring laboratory competence. Procedural efficiency is a potentially significant factor in customized IVF care, as evidenced by the correlation between longer operating times and worse clinical outcomes. In certain clinical situations, a focused stimula tion and aspiration approach might be suitable without obviously jeopardizing cu mulative results.

    A dual-drug nanocarrier strategy for ocular fungal infections: Micelles embedded in electrospun nanofibers
    (MDPI Publishing, 2026) Uzel, Egemen; Durgun, Meltem Ezgi; Aydilek, Neriman; Hacıoğlu, Mayram; Güngör, Sevgi; Özsoy, Yıldız
    Ocular fungal diseases are associated with severe infection and pain and, in advanced stages, can lead to vision loss. Current treatment options are limited to the topical ap plication of conventional drugs, and the bioavailability of these drugs is quite limited due to ocular barriers. In this study, a dual-drug nanodelivery system was developed to improve intraocular drug delivery by combining antifungal and anti-inflammatory therapies. Posaconazole (PSC), a broad-spectrum triazole antifungal agent, and dexke toprofen trometamol (DKP), a rapidly acting nonsteroidal anti-inflammatory drug, were co-loaded onto polymeric micelles and then incorporated into electrospun poly(vinyl alco hol)/poly(vinylpyrrolidone) (PVA/PVP) nanofiber intraocular implants. DSC, XRD, FTIR, and FESEM analyses showed that both APIs were successfully converted into nanofiber form without disrupting the micelle structure. Comparative studies with DKP solution and PSC commercial oral suspension (Noxafil® 40 mg/mL) showed that the produced micelle loaded nanofibers provided sustained release and significantly increased ex vivo ocular permeation and penetration. In vitro antifungal activity tests demonstrated efficacy against Candida albicans, and HET-CAM toxicity tests showed that the micelle-loaded nanofibers were non-irritating and suitable for ocular application. Overall, the micelle-loaded electro spun nanofiber ocular inserts developed in this study represent a promising platform for combined antifungal and anti-inflammatory ocular therapy.

    Comparison of neuropsychological side effects between contemporary radiofrequency ablative neurosurgery for psychiatric disorders and conventional neurosurgical procedures: Systematic review and meta-analysis
    (BMJ Publishing Group, 2026) Vilela Filho, Osvaldo; Bannach, Matheus A.; Martins Lino Filho, Adriano; Hamani, Clement; Nuttin, Bart; Hariz, Marwan; Schulder, Michael; David Greenberg, Benjamin; Yılmaz, Atilla; Gonçalves Ferreira, António
    Background Psychiatric disorders are increasingly contributing to global disability. Despite advances in conservative management, the prevalence of treatment-resistant cases remains high. Meanwhile, neurosurgery for psychiatric disorders (NPD) remains underused, largely due to strict regulations and historical concerns, particularly those related to neuropsychological side effects (NPSE). Objective To address this issue, we conducted a systematic review with meta-analysis to compare NPSE associated with radiofrequency ablative NPD to those observed in neuro-oncological, neurovascular and epilepsy surgeries. Methods PubMed, Embase and LILACS databases were searched in April 2024 for articles published in English/Spanish from 1990 to 2022, following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results A total of 48 articles with 2678 participants were included. The frequency of transient and permanent NPSE in the NPD group ranged from 0.94% to 11.50% and 0.94% to 2.03%, respectively, comparable to the other surgical groups (epilepsy: 0.31–11.70%; vascular: 0.52–22.90%; oncology: 0.94–17.60% for transient NPSE; epilepsy: 0.31–12%; vascular: 0.40–1.96% and oncology: 0.84–1.48% for permanent NPSE). Regarding permanent NPSE, arguably the most critical consideration, the NPD group showed better outcomes in memory, language and social cognition than the epilepsy group, but worse outcomes in executive and perceptual-motor functions. Compared with the vascular group, the NPD group had better executive function but worse complex attention. Finally, the NPD group had fewer permanent deficits than the oncology group in executive function, complex attention and perceptual-motor domains, although language performance was lower. Conclusions Contemporary NPD apparently carries a similar risk of NPSE as other conventional neurosurgical procedures, challenging misconceptions and this unjustified barrier to its broader use.

    A green electrochemical sensor based on molecular imprinting for etoposide detection in environmental matrices
    (Elsevier, 2026) Al Faysal, Abdullah; Kaya, Beril Sena; Dorreh, Setareh; Erdoğan, Taner; Gölcü, Ayşegül
    A semisynthetic form of podophyllotoxin, etoposide (ETO), is frequently used to manage multiple types of cancer, including lung, testicular, bladder, prostate, and gastric malignancies. Having been utilized in clinical settings for over twenty years, it is one of the most frequently prescribed anticancer agents globally. The primary cytotoxic mechanism of ETO involves the inhibition of topoisomerase II. In the present work, an innovative electrochemical detection platform utilizing MIP was successfully established to enable both highly selective and exceptionally sensitive determination of ETO in pharmaceutical injection forms and environmental specimens. An ETO-specific MIP sensor was fabricated through a photopolymerization process and immobilized onto a GCE, where AMPS served as the active monomer, and EGDMA functioned as the cross-linking agent. This study marks the first instance of a MIP-based electrochemical sensor designed explicitly for ETO identification. The AMPS ETO@MIP/GCE sensor was subjected to electrochemical and morphological assessments through FTIR, SEM, CV, and EIS. An indirect measurement approach was employed using a 5.0 mM potassium ferricyanide/ferro cyanide system to ascertain the analytical detection range from 1.0 to 10.0 pM. The sensor demonstrated excellent sensitivity, reproducibility, and selectivity, enabling effective discrimination of ETO from structurally similar compounds while retaining reliable performance in complex matrices such as soil and tap water. Results from validation experiments in pharmaceutical matrices indicated superior recovery, supporting the sensor's practical effectiveness and stability. To further investigate the experimental results and better understand the nature of template–monomer interactions, a series of DFT calculations was performed. Binding energies were evaluated for ETO–AMPS complexes across varying template-to-monomer ratios.

    Predictors of re-biopsy in percutaneous musculoskeletal tumor biopsies: A single-center retrospective cohort study
    (SAGE Publications, 2026) Yücesan, Ali; Arıkan, Yavuz; Doğukan, Fatih Mert; Mutlu, İlhan Nahit; Toy, Serdar; Atan, Tamer; Özer, Devrim
    Purpose: This study aimed to evaluate the diagnostic success of percutaneous biopsies performed for suspected mus culoskeletal tumors and to identify clinical, anatomical, and procedural factors associated with the need for repeat biopsy (re-biopsy). The secondary objective was to assess the impact of multidisciplinary team (MDT) evaluation on reducing unnecessary re-biopsy procedures. Methods: A total of 565 patients (331 bone, 234 soft tissue lesions) who underwent percutaneous biopsy for suspected musculoskeletal tumors between 2020 and 2024 were retrospectively analyzed. Diagnostic success was defined as a biopsy yielding a definitive histopathological diagnosis sufficient to guide treatment planning without additional tissue sampling. Predictive factors including lesion size, depth, location, and performing specialty were evaluated using univariate and multivariate logistic regression analyses. Results: The initial diagnostic yield was 65.5%. Multivariate analysis revealed that lesion width <2 cm (OR = 2.01; 95% CI, 1.19–3.39; p = 0.009) and biopsy performed by an interventional radiologist (compared to an orthopedic surgeon) (OR = 5.25; 95% CI, 2.83–9.74; p < 0.001) were independent predictors of re-biopsy recommendation. Among 72 patients recommended for re-biopsy, MDT evaluation averted the need for a second procedure in 38 cases (52.8%). Conclusion: Smaller lesion size (<2 cm) and the medical specialty performing the biopsy were independent predictors of re-biopsy recommendation, with the latter likely reflecting systematic differences in case complexity and procedural environment rather than operator skill. Structured MDT evaluation significantly reduced unnecessary repeat procedures.

    Thermoresponsive sol–gel system incorporating oleuropein-rich olive leaf extract for enhanced wound healing and antibiofilm activity
    (MDPI Publishing, 2026) Alparslan, Levent; Özdemir, Samet; Karacan, Burak; Torkay, Gülşah; Bal Öztürk, Ayça; Tutar, Ömer Faruk; Özcan Bülbül, Ece; Sardaş, Semra; Kala, Zübeyde Merve; Özalp, Yıldız
    Oleuropein, the principal secoiridoid phenolic compound of olive leaves (Olea europaea L.), is recognized for its broad-spectrum antimicrobial, antibiofilm, antioxidant, and tissue regenerative properties. However, its effective local therapeutic application remains chal lenging due to rapid clearance from the site of administration and limited residence time. In this study, an oleuropein-rich aqueous olive leaf extract was incorporated into a ther moresponsive sol–gel delivery system designed for localized application. The formulation was engineered to remain in a low-viscosity sol state at room temperature and to undergo a temperature-triggered sol-to-gel transition near physiological temperature (~33 ◦C), en abling in situ gel formation. Oleuropein content was quantified using a validated HPLC method, and the formulation was characterized with respect to physicochemical parame ters, thermoreversible gelation behavior, particle size distribution, mechanical properties, and spreadability. Biological performance was evaluated through in vitro cytocompati bility (MTT assay), fibroblast migration (scratch assay), and collagen deposition (Sirius Red staining) in L929 fibroblasts, as well as antibiofilm activity against representative Gram-positive and Gram-negative bacterial strains. The developed sol–gel system demon strated stable physicochemical characteristics, rapid and reversible thermogelation, suitable mechanical and spreading properties, concentration-dependent inhibition of biofilm for mation, and acceptable cytocompatibility within the tested concentration range. Notably, the formulation supported fibroblast viability and collagen-associated responses at opti mized concentrations. Overall, the results indicate that the proposed thermoresponsive sol–gel formulation represents a promising strategy for the localized delivery of oleuropein rich olive leaf extract, combining physicochemical stability with dual wound-healing and antibiofilm functionality.

    Development of biodegradable alginate films with aloe vera and quince seed mucilage: Physical, chemical, and biological properties
    (Elsevier, 2026) Keke, Zeynep Serra; Temizkan Özdamar, Kevser; Alanalp, Mine Begüm; Altıner Kurt, Eda
    In this study, novel biodegradable hydrogel films derived from quince seed mucilage and Aloe vera gel were developed and evaluated for their physical, chemical, and biological properties. Four film formulations prepared by solvent casting were characterized for swelling capacity (2.61–11.95 g), solubility (61.70–99.15%), thermal stability (TGA/DTG), chemical structure (FT-IR), surface morphology (SEM), optical properties (UV–Vis), me chanical performance (tensile strength ranging from 7.4 to 12.7 MPa), antibacterial activity, antioxidant ca pacity, and biodegradability. Quince seed mucilage enhanced the mechanical strength and thermal stability of the films due to its high-viscosity polysaccharide structure. In contrast, Aloe vera gel significantly increased the films' biological activity, particularly their antioxidant potential. Films with higher quince seed content exhibited greater structural stability, whereas Aloe vera–rich films showed increased short-term bioactivity and stronger antioxidant performance. Overall, the results indicate that hydrogel films produced from environmentally friendly and sustainable natural components can serve as functional, biologically active, and promising alter native packaging materials.
