Article Metformin Attenuates PTZ-Induced Seizures and Cognitive Impairment and Is Associated with Altered NOS/NO Signaling: Combined in Vivo and in Silico Evidence(Taylor & Francis Ltd, 2026) Ciltas, Arzuhan Cetindag; Sahin, Bilal; Hacisuleyman, Levent; Çetindağ Çiltaş, ArzuhanBackground: Epilepsy remains a major neurological disorder with high rates of drug resistance and cognitive decline. Repurposing neuroprotective drugs offers a promising approach. Metformin, a widely used antidiabetic agent, has shown anticonvulsant effects, yet its impact on nitric oxide synthase (NOS) isoforms in distinct brain regions remains unclear. Methods: Adult male Wistar rats were allocated into control, pentylenetetrazole (PTZ), or metformin+PTZ groups. Metformin (200 mg/kg, i.p.) was administered for 7 days before induction of acute PTZ seizures (45 mg/kg, i.p.). Seizure severity and latency were assessed using Racine's scale, and cognition was evaluated by the passive avoidance test (PAT). Nitric oxide (NO) and the expression of its synthesizing enzymes, inducible (iNOS), neuronal (nNOS), and endothelial (eNOS), were quantified in the cortex and hippocampus via enzyme-linked immunosorbent assay (ELISA). In silico analyses included target prediction and molecular docking to assess metformin - NOS interactions. Results: Metformin significantly reduced seizure severity, prolonged latency to the first myoclonic jerk, and prevented PTZ-induced memory impairment (all p < 0.001). These behavioral effects were accompanied by reductions in cortical and hippocampal nNOS and iNOS expression, decreased cortical eNOS levels, and lower NO accumulation. TargetNet predicted NOS isoforms among potential metformin targets, and docking indicated moderate binding affinity (-5.2 to -5.9 kcal/mol). Conclusion: Metformin exerted seizure-suppressing and cognition-preserving effects in an acute PTZ model, associated with reductions in NOS isoform expression and NO levels, suggesting altered NOS/NO signaling and supporting its potential as an adjunctive candidate for mitigating seizure-related neuronal dysfunction.Article Citation - WoS: 2Effectiveness of Vibration in Reducing Pain and Improving Satisfaction During Subcutaneous Injections: A Randomized Crossover Clinical Trial(Taylor & Francis Ltd, 2025) Yildirim, Dilek; Kugu, EmreAimThe pain experienced during and after the injection may cause discomfort and lead individuals to develop a negative perception toward future injections. This study aimed to evaluate the impact of vibration stimulation on pain induced by subcutaneous injections and patient satisfaction.MethodsThis was a prospective, randomized, single-blind, crossover study design. Data were collected from 85 patients. Vibration and non-vibration subcutaneous anticoagulant injections were administered randomly by the same investigator following a standardized procedure. Pain and satisfaction were evaluated by a study-blind investigator using the Visual Analogue Scale immediately after the injection. Data were analyzed using descriptive statistics, the Student's t-test, paired sample test, and a generalized linear mixed model.ResultsA total of 175 injections were analyzed. It was found that the pain level of patients was lower when vibration was applied (4.06 +/- 1.68 vs. 5.32 +/- 2.19, p = 0.004). Additionally, patient satisfaction was higher when vibration was used (7.17 +/- 1.71vs. 5.97 +/- 2.46, p = 0.011).ConclusionThe results of this study demonstrated that vibration was effective in reducing the pain associated with subcutaneous anticoagulant injections and in increasing patient satisfaction. Vibration can be used as a method to alleviate pain from subcutaneous anticoagulant injections and enhance patient satisfaction. Clinically, this suggests that incorporating vibration during subcutaneous injections can be a simple, non-pharmacological strategy to improve patient comfort and adherence to therapy.Article The Effect of Mirror Therapy on Spasticity in Adult Patients With Stroke: a Systematic Review and Meta-Analysis(Taylor & Francis Ltd, 2025) Tosun, Anil Tekeoglu; Isiklar, Cagdas; Yeldan, Ipek; Tekeoğlu Tosun, AnılObjective This study aims to investigate the effects of Mirror Therapy (MT) on spasticity and related parameters in stroke patients Methods A systematic review was performed in databases PubMed, Web of Science, Science Direct, Cochrane, and Scopus databases for published RCTs (Randomized Controlled Trials) from the date of each database's inception to May 2021. Modified Ashworth Scale (MAS) in adult patients with stroke compared to conventional therapy, sham, and additional therapy control were included. Physiotherapy Evidence Database Scale was used to assess the methodological quality of each study. Results The overall effect of MT on MAS was statistically significant and beneficial when studies were analyzed in terms of both upper and lower extremities (p < 0.001). MT demonstrated a large and beneficial overall effect on the Brunnstrom Assessment compared to conventional therapy (p < 0.001). The overall impact of MT on Fugl-Meyer Assessment (FMA) was large and statistically significant (p < 0.001). However, a meta-analysis of three studies using the 10-meter walk test showed that the overall effect of MT was not statistically significant (p = 0.258). Conclusion This systematic review and meta-analysis demonstrates reductions in upper and lower extremity spasticity and improved motor recovery with MT, both isolated and combined with other treatments, in adults with stroke.

In this cross-sectional study, which 6332 adults were included, fruit and vegetable consumption, and preferences were collected. The quantities of vegetables and fruits were classified based on the WHO and the national recommendations. Of the adults (33.39 +/- 12.59 years), 52.9% of men and 39.7% of women had an above-normal BMI. Based on WHO recommendations, overweight and obese people consumed less vegetables and fruits compared to their counterparts (ORs for women, overweight: 1.2, obese: 1.3; ORs for men, overweight: 1.3, obese: 1.5; 95% CI). The regression analysis revealed that the quantities of vegetable and fruit intake were higher in young individuals, men, and married people. Although the majority consume more than 400 g/day of vegetables and fruits, the intake is inadequate in people with obesity.Article Citation - WoS: 2Citation - Scopus: 1A New Perspective on Osas Cases With the Baveno Classification(Taylor & Francis Ltd, 2024) Koseoglu, Handan Inonu; Aykun, Goekhan; Kanbay, Asiye; Pazarli, Ahmet Cemal; Yakar, Halil Ibrahim; Demir, Osman; Inonu Koseoglu, HandanObjective/Background: Since the apnea-hypopnea index (AHI), which is used in the diagnosis and grading of OSAS, does not adequately reflect the clinical perspective of the disease, the Baveno classification of OSA was developed, which allows multicomponent evaluation of OSAS patients. The aim of our study was to evaluate the application of the Baveno classification in clinical practice. Patients/Methods: A prospective study was performed on patients diagnosed with OSAS between January 2021 and June 2022. Patients were divided into 4 groups according to Baveno classification (Groups A-D) and three groups as mild, moderate, and severe OSAS according to AHI. Results: A total of 378 patients (70% male, mean age 48.68 +/- 11.81 years) were included in the study. The patients had mild (n: 75; 20%), moderate (n: 88; 23%), and severe (n: 215; 57%) OSAS. According to Baveno classification, patients were included in Groups A (n: 90; 24%), B (n: 105 (28%), C (n: 65; 17%), and D (n: 118; 31%). The mean AHIs of the Baveno groups were similar (p = 0.116). Oxygen desaturation index (ODI) was higher in Groups B and D compared to Group A. The duration of T90 desaturation was longer in Groups C and D compared to Groups A and B (p < 0.05). Conclusions: The Baveno classification divided our OSAS cases into equivalent groups. One out of every four patients with mild OSAS was in Group D. This data was noteworthy in that the Baveno classification allows for the identification of symptomatic and comorbid patients with mild OSAS according to AHI and for the application of more effective treatments to these patients. Patients with comorbidities experienced oxygen desaturation for a longer period of time at night, and oxygenation deteriorated in patients with prominent symptoms. Baveno classification was found to be a more reasonable and easily applicable approach in clinical practice.Article Citation - WoS: 1Histological and Biochemical Effects of an Ethanolic Extract of <i>myrtus Communis</I> Leaf on the Pancreases of Rats Fed High Fat Diets(Taylor & Francis Ltd, 2024) Kabatas, Gul Sinemcan; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha; Akakin, DilekWe investigated the effects of an ethanolic extract of Myrtus communis subsp. communis (MC) leaves on the pancreases of rats fed with a high fat diet (HFD). Wistar albino rats were fed either with standard lab chow (Control group) or with a 45% fat diet (HFD and HFD+MC groups) for 4 months, with the MC extract (100 mg/kg) being administered by orogastric gavage to rats in the HFD+MC group during the last month. Blood and pancreas samples were collected from all experimental groups at the end of the study. Insulin and leptin levels, and the lipid profile, were analyzed in the blood serum. Pancreatic injury was assessed histologically. Insulin, nuclear factor kappa beta (NF-kappa B), and alpha-smooth muscle actin (alpha-SMA) were assessed using immunohistochemistry. Apoptosis was assessed using terminal deoxynucleotidyl transferase dUTP nick end-labeling (TUNEL) immunohistochemistry. In addition, oxidant/antioxidant activity was analyzed by biochemical methods. Increased body weight, serum insulin and leptin levels, blood glucose level and pancreatic tissue malondialdehyde (MDA), 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels, myeloperoxidase (MPO) activity and decreased tissue glutathione (GSH) level were observed in the HFD group compared to the Control group, in addition to dyslipidemia. An increased histopathological damage score, pancreatic islet area, insulin, TUNEL, NF-kappa B and alpha-SMA immunoreactivity were seen in animals from the HFD group compared to the Control group. However, such pathological changes were reduced in the HFD+MC group. Our data indicate further investigation of MC extract as a therapeutic adjuvant for HFD-induced pancreatic injury, acting via anti-inflammatory and antioxidant mechanisms, is worth carrying out.Article Citation - WoS: 1Ameliorative Effects of Myrtus Communis L. Extract Involving the Inhibition of Oxidative Stress on High Fat Diet-Induced Testis Damage in Rats(Taylor & Francis Ltd, 2024) Coskunlu, Busra; Koroglu, M. Kutay; Hersek, Irem; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, FerihaThe possible protective effects of Myrtus communis L. (MC) extract on a high fat diet (HFD)-induced testicular injury in a rat model were investigated using histological and biochemical methods. Wistar albino rats were divided into three groups: a standard diet control group; a HFD group; and an HFD+MC group. The HFD and HFD+MC groups were fed with a HFD for 16 weeks. MC extract (100 mg/kg) was given orally five days a week to the rats in the HFD+MC group during the last four weeks of the experiment. Leptin, triglyceride, high-density lipoproteins, cholesterol, estrogen, testosterone, LH and FSH were analyzed in blood serum. Sperm parameters were evaluated from the epididymis. Testicular morphology, proliferative, apoptotic and NADPH oxidase-2 (NOX2)-positive cells were evaluated histologically. Testicular oxidative stress parameters were analyzed biochemically. In the HFD group, lipid and hormone profiles were changed, abnormal spermatozoa, degenerated seminiferous tubules with apoptotic and NOX2-positive cells were increased in number, and sperm motility and germinal proliferative cells decreased compared to the control group. Moreover, testicular malondialdehyde, 8-hydroxy-2-deoxyguanosine and myeloperoxidase levels increased, whereas glutathione and superoxide dismutase levels decreased in the HFD group compared to the control group. All these histological and biochemical features were ameliorated by MC treatment of HFD-fed rats. In conclusion, HFD caused alterations in sperm parameters and testicular morphology by increasing oxidative damage and apoptosis. MC extract may have potential protective effects by inhibiting oxidative damage.Article Citation - WoS: 4Citation - Scopus: 3Correlations Between the Screen Time of Children With Special Needs and Their Parent-Child Relationships, Home Participation, and Occupational Performance(Taylor & Francis Ltd, 2024) Akyurek, Gokcen; Aydoner, Selen; Gundogmus, Ezginur; Gunal, Rumeysa; Ozan, Aysenur Demir; Demir Ozan, AysenurThis study aimed to examine the relationships between the screen time of children with special needs and of their parents with their home participation, occupational performance, and parent-child relationships according to sex and diagnosis. Parents of 150 children with special needs (age range, 4 to 6 years) such as autism spectrum disorder, cerebral palsy, and attention deficit hyperactivity disorder, as well as undiagnosed and developmentally risky children, were included. The Demographic Information Form, Screen Time Usage Form, Parent-Child Relationship Scale, Participation and Environment Measure for Children and Youth, and Short Child Occupational Profile were used for the data collection. There was a significant relationship between the screen time of girls and their parent-child relationships, home participation, and occupational performance. Moreover, we detected a relationship between the screen time of children with autism spectrum disorder and positive parent-child relationships, home participation, and occupational performance. Therapists should account for screen time in their interventions associated with parent-child relationships, home participation, and occupational performance.Article Citation - WoS: 8Citation - Scopus: 11The Psychometric Properties of the Figure-Of Walk Test in People With Parkinson's Disease(Taylor & Francis Ltd, 2023) Soke, Fatih; Erkoc Ataoglu, Nigar Esra; Ozcan Gulsen, Elvan; Yilmaz, Oznur; Gulsen, Cagri; Kocer, Bilge; Tokcaer, Ayse BoraPurpose To investigate: (1) the interrater, and test-retest reliability of the figure-of-eight walk test (F8WT) in people with Parkinson's disease (PwPD); (2) the minimum detectable change in the F8WT times; (3) the concurrent and known-groups validity of the F8WT times; and (4) the cut-off times that best discriminate PwPD from healthy people and fallers from non-fallers with PD. Methods This was a cross-sectional study. Forty-three PwPD and 34 healthy people were recruited. The F8WT was performed along with the timed up and go test, 10 m walk test, Berg Balance Scale, Activities-Specific Balance Confidence Scale, Unified Parkinson's disease Rating Scale, and Hoehn and Yahr Scale. Results The F8WT showed good interrater and test-retest reliability (ICC = 0.964-0.978 and ICC = 0.905-0.920, respectively). The MDC was 2.77 s. The F8WT was correlated with other outcome measures. Significant differences in the F8WT times were found between PwPD and healthy people and between fallers and non-fallers with PD (p < 0.001 and p < 0.001, respectively). The cut-off times of 8.43 s best discriminated PwPD from healthy people, while 11.19 s best discriminated fallers from non-fallers with PD. Conclusions The F8WT is a reliable, valid, and easy-to-administer tool in assessing the walking skill of PwPD.
