Adolesan kadın basketbol oyuncularında anaerobık yorgunluğun proprıosepsıyon üzerıne etkısı
(Turkey AsSoc Physiotherapists, 2025) Kilic, Sefa; Alpay, Kubra; Atici, Emine; Soyal, Mehmet; Inal-Gultekin, Guldal
Proproseptif duyudaki eksiklikler yaralanma riskini artırmakta ve sporcunun performansını olumsuz yönde etkilemektedir. Kadın basketbol oyuncularında anaerobik yorgunluğun ve toparlanma sürecinin propriosepsiyon üzerine etkisi üzerinde sınırlı sayıda çalışma bulunmaktadır. Bu amaçla adolesan kadın basketbol oyuncularında anaerobik yorgunluğun alt ekstremite propriosepsiyonu üzerine etkisini değerlendirilmiştir. Çalışmaya 12–16 yaş aralığında 30 lisanslı kadın basketbol oyuncusu dahil edildi. Katılımcıların demografik bilgilerine takiben, istirahat, yorgunluk ve toparlanma olmak üzere üç durumda kalp atım sayıları, 30° ve 60° aktif ve pasif diz eklemi pozisyon hissi ölçümleri yapıldı. Diz eklemi pozisyon hissi ölçümleri için dominant bacakları değerlendirmeye alındı. Anaerobik yorgunluk için bisiklet ergometresinde Wingate anaerobik test protokolü uygulandı ve hemen sonrasındaki yorgunluk durumu verileri alındı. Toparlanma sonrası verilerin alınması için katılımcılar 10 dakika istirahate alındılar. Katılımcıların elde edilen yorgunluk nabızları ortalama 171,6±4,2 atım/dakika olarak tespit edildi ve karvonen formülüne göre hesaplanan iş yoğunluğu %72,7±2,9 olarak belirlendi. Anaerobik yorgunluk sonrası 30° ve 60° diz fleksiyonu aktif eklem pozisyon hissinde istirahat değelerine göre anlamlı azalma saptandı (p>0,017). Yorgunluk sonrası 10 dakikalık toparlanma ile 30° ve 60° diz fleksiyonu aktif eklem pozisyon hissinde tekrar istirahat seviyelerine dönüş olduğu belirlendi. Diz fleksiyonu 30° ve 60° pasif eklem pozisyon hissinde anaerobik yorgunluk sonrası anlamlı farklılık tespit edilmedi. Sonuç olarak, adolesan kadın basketbolcularında anaerobik yorgunluğun diz propripsepsiyonunu azalttağı saptanmış ve çalışmanın literatürdeki benzer bulgularla örtüştüğü görülmüştür. Bunula birlikte, 10 dakika kadar kısa bir toparlanma süresi ile propriyoseptif duyarlılığın başlangıç seviyelerine geri döndüğü görülmüştür.
Advancing Ovarian Cancer Care: Recent Innovations and Challenges in the Use of MXenes and Their Composites for Diagnostic and Therapeutic Applications
(Royal Soc Chemistry, 2025) Farzizadeh, Neda; Zarepour, Atefeh; Khosravi, Arezoo; Iravani, Siavash; Zarrabi, Ali
Ovarian cancer remains the deadliest form of gynecologic malignancy, largely owing to the absence of reliable early diagnostic tools and the limited effectiveness of current therapeutic strategies. Recent advances in nanotechnology-particularly the emergence of two-dimensional materials known as MXenes-offer promising avenues to address these challenges. This review highlights the emerging role of MXenes and their composites in the management of ovarian cancer, focusing on their potential in biomarker detection and targeted treatment strategies. We provide a comprehensive analysis of the latest studies examining the physicochemical features of MXenes, their synthesis and surface functionalization approaches, and their application in ovarian cancer, including biosensing, drug delivery, and combinatorial therapeutic systems. MXene-based biosensors have shown remarkable detection limits in detecting ovarian cancer biomarkers, such as cancer antigen 125 (CA125), human epididymis protein 4 (HE4), lipolysis-stimulated lipoprotein receptor (LSR), and carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5). However, several challenges remain, including issues of biocompatibility, structural stability, and clinical scalability. Continued interdisciplinary research is essential to address these limitations, optimize MXene functionalization, and translate their laboratory success into clinical settings. With appropriate advancements, MXenes hold significant promise for enabling more precise, efficient, and patient-specific approaches to ovarian cancer diagnosis and therapy.
Alternative Treatment for Refractory Jacquet Dermatitis After Hirschsprung Disease Surgery: a Case Report
(Elsevier, 2025) Kilic, Sinan; Guven, Ahmet; Isik, Sakine
Introduction: Jacquet's erosive diaper dermatitis (JDD) is a severe form of diaper dermatitis, characterized by papuloerythematous erosions with crater-like borders in the genital and perianal regions. Case presentation: A 2-year-old male patient was diagnosed with Hirschsprung disease (HD) during the neonatal period. A transition zone was detected in the rectosigmoid region on a contrast enema. Full-thickness rectal biopsy confirmed aganglionosis, and a colostomy was created from the transverse colon. At 18 months of age, the patient underwent the Swenson procedure, and the colostomy was closed during the same session. Following the operation, spontaneous stool passage was achieved. Approximately six months after surgery, ulcerative lesions characteristic of Jacquet dermatitis developed in the perianal region. Despite six months of treatment with moisturizers, regenerative, epithelializing, and barrier therapies (e.g., zinc oxide, madecassoside, shea butter, glycerin, oatmeal, hyaluronic acid), the lesions did not improve. However, after initiating treatment with pure Aloe Vera gel, including a 10 % diluted natural extract applied four times daily, plus a dairy-free diet for three weeks, a rapid clinical response was observed, with visible improvement within the same period. Conclusion: The combination of Aloe Vera-based ointment plus dairy-free diet seems to be an effective management strategy for children with post pull-through Jacquet's dermatitis.
Analysis and Implementation of Sensorless Pmsm Drive With Reduced Dc-Link Capacitance Under Parameter Variations
(Ieee, 2024) Sumsek, Reha Ozgur; Calik, Ramazan; Yavuz, Fikri Serkan; Kivanc, Omer Cihan
In AC drives used in heating, ventilation and air-conditioning applications, film capacitors are becoming widespread instead of electrolytic capacitors in DC-link. These drives with reduced capacitor value provide cost and volume advantages. However, dc-link oscillation increases due to the reduced capacity value. These oscillations cause instability, overvoltage and an increase in total harmonic distortion (THD). On the other hand, the winding temperatures of these motors, which operate continuously under rated operating conditions, reach 80 degrees C. The stator resistance and rotor flux value, which change with the increase in temperature, cause these drives, controlled without sensors, to operate even more unstable. In this study, a hybrid approach is proposed to improve the performance of the inverter using a 16 mu F film capacitor at the dc-link and to reduce the THD. The active damping method regulates the inverter output voltage for DC-link voltage stabilization. A permanent magnet synchronous machine (PMSM) sensorless speed control based on stator feedforward voltage estimation and a model reference adaptive system (MRAS) based on a multiparameter estimation algorithm is performed to minimize the effects of parameter variations. As a result of the experimental studies, it is observed that the grid input current complies with the IEC61000-3-2 standard, even under severe parameter variations.
Antioxidant Activity, Chemical Composition, and Therapeutic Activity of Essential Oils from Certain Lamiaceae Species in Türkiye
(Marmara Univ, Fac Pharmacy, 2025) Goksu Surucu, Canan; Dumlupinar, Berrak; Gurbuz, Burcak; Seker Karatoprak, Gokce; Bahtiyarca, Reyhan; Ilgun, Selen
The study examined the antioxidant, antimicrobial, and potential anticancer properties of lavandin (Lavandula x intermedia 'Grosso'), oregano (Origanum vulgare 'Ulu & gbreve; Bey'), and sage (Salvia officinalis 'Beyhekim') essential oils (EOs). Chemical analysis revealed that oregano is rich in carvacrol (81.23%), cymene (5.51%), and 18-cineole (2.13%). Sage contains notable quantities of alpha-thujone (17.47%), camphor (13.59%), and borneol (12.14%). Lavandin is predominantly composed of linalool (41.10%), linalyl acetate (16.66%), and camphor (10.01%). The antimicrobial tests demonstrated that lavandin EOs exhibited a high inhibition rate of 90.77% at 1000 pg/mL, which subsequently decreased with lower concentrations. The oregano essential oils demonstrated robust antimicrobial activity across all concentrations, with a 10.97% inhibition rate observed even at the lowest concentration. The sage EOs exhibited a rapid decline in antimicrobial activity, reaching 4.97% at the lowest concentration. Both the DPPH and ABTS assays demonstrated that the antioxidant capacity of the essential oils was concentration-dependent. The cytotoxicity values of oregano essential oil were 35.58 at 50 pg/mL, 32.39 at 25 pg/mL, and 30.92 at 12.5 pg/mL. Similar cytotoxicity results were observed for sage and lavandin essential oils. These findings indicate that plant essential oils exert a dose-dependent cytotoxic effect on cell growth, significantly inhibiting cells at high concentrations. The research indicates that essential oils derived from Lamiaceae plants exhibit robust antimicrobial effects against a range of pathogens, suggesting potential applications as alternative therapies for specific microbial infections, comparable to ciprofloxacin at certain concentrations.
Assessing Parents Perception of Environmental Awareness
(Stef92 Technology Ltd, 2013) Ozyaral, O.; Ayra, F.; Kaya, E.
It is inevitable to avoid from the influences of some adversities to arise in the ecosystem as "environmental risks" on our lives. The present study aims to determine the level of perception of parents on environmental awareness and environmental protection and to raise awareness on the environmental value and protection. In the present study, the questionnaires were administered to the parents of two private kindergarten students in Ki{dotless}zi{dotless}ltoprak-Erenköy districts on the Asian side of Istanbul as well as the parents of first and second grade students of a private primary school in Umraniye district on the Asian side of Istanbul. The parents of these first and second grade students and the kindergarten students were asked to fill in these questionnaires. A questionnaire prepared by the researchers and consisting of 76 questions was administered to the parents of the kindergarten students in order to measure their parents' environmental perception, 12 of which were prepared to measure the demographic characteristics and 64 of which were prepared for the perception measurement. In the study, the relations between the socio-economic and demographic characteristics of the parents and their environmental perceptions were tried to be found out. Moreover, to what extent the parents put into practice what they know was analyzed so that it can be shown how the information acquired affects the behavior acquisition. In line with the findings obtained, the fact that the awareness of the parents themselves on environment and ecosystem should be improved so that they can transfer the proper actions and approaches they have internalized to their children was found out. Emphasizing the environmental education in every part of the life and providing this education through non-governmental organizations and the experts and the efficiency of the media in this regard were among the results. In addition, the environmental awareness studies should begin during childhood for the sustainability of the environmental awareness education and the media studies should be heavily focused on so that the socio-cultural behavior changes could be ensured in the society and the social media studies should be made. © SGEM2013 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.
The AsSociation Between Monocyte/HDL-C Ratio and Heart Failure
(Marmara Univ, Fac Pharmacy, 2025) Cattik, Busra Nur; Aksoy, Nilay; Berk, Barkin; Gungor, Baris
The monocyte/HDL-cholesterol ratio (MHR) was shown to be a marker of inflammation. This study investigated the utilization of this ratio as a measure of severity for heart failure which is a condition asSociated with inflammation. The MHR was calculated for 323 ambulatory patients with chronic heart failure and compared to other variables asSociated with the severity of the condition. Additionally, the impact of MHR on the Seattle Heart Failure Model (SHFM) score was investigated. MHR correlated positively with C-reactive protein (r: 0.312, p<0.001) and neutrophil-to-lymphocyte ratio (r: 0.242, p<0.001), but not with platelet-to-lymphocyte ratio. In addition, a correlation was found between the SHFM score and MHR (r:-0.267, p<0.001). The SHFM score exhibited a significant result for proB-type natriuretic peptide (pro-BNP) (p<0.001), neutrophil (p<0.001), hematocrit (p=0.001), and serum creatinine (p=0.001) in the ordinal logistic regression analysis, but not for MHR. MHR showed a negative correlation with left ventricular ejection fraction (r:-0.151, p: 0.007), exhibited a positive asSociation with pro-BNP (r: 0.184, p<0.001), and no correlation with New York Heart AsSociation classes. There is a significant correlation between the MHR value and the factors asSociated with the severity of heart failure. The prognosis and management of this condition may be assessed by utilizing the MHR value in conjunction with existing biomarkers.
Asthmatic Patients: Is Homocysteine an Issue
(Galenos Publ House, 2024) Keskinel, İlkay; Eryilmaz, Müzeyyen; Güntürk, Arzu
Objective: Understanding the causes of asthma is crucial for developing new therapeutic modalities. Homocysteine (HCY) is an intermediate in methionine metabolism. Elevated HCY levels may indicate folate and vitamin B12 deficiencies, which are cofactors for the methylation of HCY to methionine. The relationship between hyperHCY mia and atherosclerosis is well-documented, and it is considered a cause of cardiovascular, neurodegenerative, and ocular diseases. HyperHCY mia may also cause atopy and, consequently, asthma. We aimed to evaluate the levels of HCY, vitamin B12, and folic acid in asthmatic patients and healthy adults, as well as to determine whether correlations exist between these levels and lung function, eosinophil counts, total immunoglobulin E (IgE), and eosinophilic cationic protein (ECP) levels in asthmatic subjects. Methods: A total of 142 asthmatic patients and 36 healthy controls were enrolled in the study. Folic acid, vitamin B12, total IgE, ECP, eosinophil percentage, eosinophil counts, and HCY levels were evaluated in both groups. Results: HCY, vitamin B12, and folic acid levels did not significantly differ between patients with asthma and controls. There was a statistically significant positive correlation (at the 0.95 confidence level) between HCY values and forced vital capacity, peak expiratory flow (PEF), and eosinophil counts in patients with asthma. Folic acid levels correlated positively only with PEF%, whereas vitamin B12 levels did not correlate with any functional parameters or atopic markers like IgE and ECP. Conclusion: Should large-scale randomized controlled trials conclusively establish HCY as a causative factor of asthma, metabolic interventions to lower HCY levels using methyl donors could be considered alongside conventional asthma treatments.
Autoimmune Encephalitis and Musicogenic Epilepsy: a Case of Gad65 Antibody-Associated Seizure
(Wiley, 2025) Mohammadi-Asl, Ali; Bahadori, Amir Reza; Sabzgolin, Iman; Davari, Afshan; Razmafrooz, Mohammad; Tafakhori, Abbas; Ranji, Sara
Musicogenic epilepsy (ME) is a rare form of reflex epilepsy with a prevalence of 1 in 10,000,000. Recent research suggests a potential link between ME and autoimmune encephalitis, particularly involving glutamic acid decarboxylase 65-isoform (GAD65) antibodies. A 48-year-old female presented with a one-year history of music-triggered seizures. Her episodes were characterized by an initial aura followed by unresponsiveness and oral automatisms. Electroencephalography revealed abnormalities in the left anterior temporal lobe and temporal leads. Laboratory studies showed positive anti-GAD65 antibodies. The patient was treated with a combination of antiepileptic medication (Lamotrigine) and corticosteroids and intravenous immunoglobulin. This case contributes to the growing evidence supporting an association between ME and autoimmune mechanisms, particularly GAD65 antibody-mediated autoimmunity. It highlights the importance of screening autoimmune factors in ME patients and highlights the need for further research into targeted treatment strategies.

Comparative Analysis of Transaction Performance in Different Virtualization Environments
(Istanbul Univ, 2024) Candemir, Ali Ihsan; Incereis, Nilgun
Virtualization technologies are increasing in importance day by day. The selection of virtualization software is an important factor to realize efficient use of physical hardware. In this study, the Ubuntu 22.04 LTS operating system was run on VirtualBox, VMware, and Docker, which are widely used virtualization software. Then, the Tiobench, Compress-7zip, C-ray, Smallpt, Tachyon, and OSBench tests were performed on the Ubuntu operating system with the Phoronix Test Suite software, and the test results were analyzed and compared. The results demonstrate that Docker outperformed the other virtualization technologies, although not in every test. Owing to its rapid deployment and efficient use of resources, Docker is suitable for applications that require agility and scalability. However, traditional virtualization technologies, such as VMware, may be more suitable for applications that require high security and extensive resource management. In addition, this study provides information that can guide users in selecting virtualization software.
Comparison of Perioperative Outcomes and Urethral Complications Between Using 24-French and 26-French Resectoscope Sheaths in Holmium Laser Enucleation of the Prostate
(Galenos Yayıncılık, 2022) Yildiz, Ali; Akdemir, Serkan; Anil, Hakan; Guzel, Ahmet; Arslan, Murat
Aim: Although the 26F resectoscope is frequently used in transurethral prostatectomy, there are some concerns with high-caliber shafts. We compared 24F and 26F resectoscope used for Holmium Laser Enucleation of the Prostate (HoLEP) in terms of effects on postoperative urethral complications and perioperative outcomes. Methods: Data from patients undergoing HoLEP from 2017 to 2021 was retrospectively analyzed. All surgeries were completed by a single surgeon. The patients were divided into one of two groups according to the resectoscope diameter (24F or 26F). All patients were followed up for urethral complications for 12 months. Perioperative outcomes and urethral complications were compared between the groups. Results: The study included 301 patients. The mean age of patients was 68.5 +/- 8.3 and 69.1 +/- 8.6 for the 26F group (n=180) and the 24F group (n=121), respectively (p=0.608). A total of seven in the 26F group (3.8%) and 3 patients in the 24F group (2.4%) had postoperative urethral stricture (US) (p=0.503). Besides, 2 patients (26F) and 1 patient (24F) had postoperative bladder neck contracture (BNC) (p=0.807). The operation efficiency was 1.25 g/min in the 26F group and 1.17 g/min in the 24F group (p=0.005). Conclusion: The use of 24F or 26F RS was not shown to cause statistically significant differences in the incidence of US and BNC during the 12-month follow-up. The use of the 24F RS significantly reduces surgical and morcellation efficiency.
Comparison of Posterior and Antero-Lateral Renal Tumors in Retroperitoneal Laparoscopic Partial Nephrectomy: a Propensity Score Matching Analysis
(Codon Publications, 2023) Anil, Hakan; Yildiz, Ali; Guzel, Ahmet; Akdemir, Serkan; Karamik, Kaan; Arslan, Murat
This study aimed to compare the antero-lateral and posterior localized renal masses in laparoscopic partial nephrectomy with the retroperitoneal approach in terms of operative, functional, and oncological outcomes. Patients who underwent retroperitoneal laparoscopic partial nephrec-tomy by a single surgeon between January 2013 and January 2021 were included in the study. A one-to-one propensity score matching (PSM) analysis was conducted to obtain two balanced groups. The patients were divided into two groups as posterior and antero-lateral according to the localization of the mass. A total of 239 patients were included in the PSM analysis, with 65 patients allocated to each group. The mean operative time was 79.2 & PLUSMN; 11.2 min in the posterior group, while it was 90.0 & PLUSMN; 11.6 min in the antero-lateral group (P < 0.001). Warm ischemia time was 15.9 & PLUSMN; 2.4 min in the posterior group and 18.6 & PLUSMN; 2.7 min in the antero-lateral group (P < 0.001). The median decrease in eGFR at 1 year was 4.8 (IQR, 2.9-6.9) mL/min in the posterior group and 5.0 (IQR, 2.8-11) mL/min in the antero-lateral group (P = 0.219). The warm isch-emia time and clamping technique were found to be significant factors for predicting eGFR change after surgery (13:0.693, 95% CI: 0.39-0.99, P < 0.001; 13:6.43, 95% CI: 1.1-11.7, P = 0.017, respectively). We report that retroperitoneal laparoscopic partial nephrectomy provided longer warm ischemia and operative time for antero-lateral renal masses than posterior masses. However, long-term oncological and functional results were similar for both localizations.
Comparison of Three Different Modalities for the Treatment of Bladder Calculi by Size
(Sage Publications Ltd, 2022) Yildiz, Ali; Anil, Hakan; Erol, Ibrahim; Karamik, Kaan; Ercil, Hakan
Purpose: Treatment recommendations for kidney or ureteral stones are based on stone size; however, this is uncertain for bladder stones. This study aims to determine the best approach to bladder stones based on their size. Materials and methods: We retrospectively analyzed 401 patients with bladder stones. Patients were divided into three different groups according to stone size (11-20 mm, 21-30 mm, 31-40 mm as groups 1, 2, and 3 respectively). Patients had transurethral cystolithotripsy (TUCL), percutaneous cystolithotripsy (PCCL), and open cystolithotomy (OCL) performed. Results: Stone fragments were removed completely in all patients. When catheter time, postoperative stay, and hematocrit decrease values were compared, the results were significantly higher for OCL in all three groups (p: 0.001). When the relationship between stone sizes and operation time is evaluated, TUCL had shorter operation times (34.1 +/- 10.6 min) in group 1. However, TUCL had longer operation times in group 2 and group 3 compared to OCL and PCCL. Conclusion: TUCL may be preferable due to better postoperative outcomes and shorter operative time for <= 2 cm stones. As the stone size increases, PCCL is more favorable in terms of operation time.

(Elsevier, 2025) Basem, Ali; Al-Nussairi, Ahmed Kateb Jumaah; Khidhir, Dana Mohammad; Singh, Narinderjit Singh Sawaran; Baghoolizadeh, Mohammadreza; Fazilati, Mohammad Ali; Hasanabad, Ali Mohammadi
Geothermal energy storage (GES) systems are thoroughly examined in this research, with a focus on methods like borehole thermal energy storage (BTES), underground thermal energy storage (UTES), and aquifer thermal energy storage (ATES). It highlights the importance of thermal energy storage (TES) systems in addressing global energy challenges. The feasibility of UTES for large-scale energy storage and its integration with geothermal power plants is investigated. The ATES, with the advantage of large storage capacity and low operating costs has could be employed in regions with suitable aquifers. The adaptability of BTES to different ground conditions and its small land footprint made it a spotlight for the researchers. The study emphasizes the role of TES technologies in meeting the growing demand for renewable energy, reducing the impact of climate change, and providing efficient energy solutions for heating, ventilating, and air conditioning. HVAC systems. Also, the application of geothermal power plants and TES systems in decreasing the dependence on nonrenewable energy sources and increasing energy efficiency increase investigated. The development of reliable and affordable sensors, together with improvements in processing power, has made data-intensive algorithms and real-time operational decision-making applications in the field of geothermal energy. The study also delves into the potential of machine learning to optimize geothermal design, monitor performance, improve performance, find errors, and more. It was shown that artificial neural networks were the most common kind of trained model, while several other models were often used as benchmarks for performance. Picture selection, systematic time series feature engineering and model evaluation were all areas that showed a lot of promise in the systematic review for future research and practical applications.
