Article Citation - WoS: 2Citation - Scopus: 2Synthesis of Novel Thiazole/Thiadiazole Conjugates of Fluoroquinolones as Potent Antibacterial and Antimycobacterial Agents(John Wiley and Sons Inc, 2025) Poyraz Yılmaz, P.; Kulabaş, N.; Bozdeveci, A.; Vagolu, S.K.; Imran, M.; Tatar, E.; Küçükgüzel, İ.; Yilmaz, Pinar PoyrazTwenty azole-fluoroquinolone hybrids were designed and synthesized by conjugating thiazole and thiadiazole structures to ciprofloxacin and norfloxacin via a 2-oxoethyl bridge. The structures and purities of the synthesized compounds were proven by spectral techniques. The antimycobacterial effects of target compounds 21–40 were tested against Mycobacterium tuberculosis H37Rv strain. Among the 20 synthesized compounds, 12 exhibited minimal inhibition concentration (MIC) values in the range of 1.56–25 μg/mL. Among the molecules screened for antimycobacterial effects, the most effective was compound 35, a thiadiazole-ciprofloxacin hybrid. The cytotoxic effect of this molecule was found to be lower than the reference drugs, and it was also determined to be a more effective inhibitor than ciprofloxacin and norfloxacin in the DNA-gyrase supercoiling test. The antimicrobial effects of compounds 21–40 were screened by agar-well diffusion and microdilution tests against Gram-positive/negative bacteria, a fast-growing mycobacterium, and two yeast strains. While most of the compounds tested showed antibacterial effects, the most effective fluoroquinolone derivative appeared to be compound 31 with an MIC value of < 0.63 μg/mL against all Gram-negative bacteria tested. Azole-fluoroquinolone hybrids 21–40 did not show any activity against non-pathogenic Lactobacillus species and yeast-like fungi, indicating that they have selective antibacterial and antimycobacterial activity, particularly against Gram-negative bacteria. In silico molecular docking studies were conducted to uncover the interactions between lead compound 35 and the DNA gyrase proteins of M. tuberculosis and S. aureus. Additionally, a 100 ns molecular dynamics simulation was carried out to assess the stability of the complexes formed between compound 35 and both proteins. © 2025 The Author(s).

The data collection process was performed by the researchers. The interviews were recorded and transcribed. The data collected in accordance with the phenomenological approach were processed using guided content analysis.ResultsIn the interview with the participants, whose mean age was 21.86 +/- 2.03 years and 66.7% of those were female, 6 themes were listed as positive and negative experiences of students in diabetes management in the university environment, general nutritional preferences, nutritional attitudes in non-routine and social environments, regular nutrition and quality of campus life, nutrition during the exercise/sports period, university support and students' expectations from the environment and explained by their sub-dimensions.ConclusionThe change in living conditions with the transition to campus life, the new social environment, individualization and academic responsibilities make diabetes self-management a challenging, complex and supportive process. This study might guide the enhancement of university students' living conditions with diabetes.Article Cross-Cultural Adaptation, Validity, and Reliability of the Turkish Version of the Cumberland Ankle Instability Tool for Athletes(Human Kinetics Publ Inc, 2025) Yazgan, E.A.; Karagözoğlu Coşkunsu, D.; Razak Özdinçler, A.R.; Coşkunsu, Dilber Karagözoğlu; Özdinçler, Arzu RazakCONTEXT: To cross-cultural translate the Cumberland Ankle Instability Tool (CAIT) to Turkish version (CAIT-T) and to evaluate the validity, reliability, and cutoff score of CAIT-T for Turkish athletic population. DESIGN: The English version of CAIT was translated to CAIT-T based on a guideline of cross-cultural adaptation. Fifty-two athletes with chronic ankle instability and 63 athletes without chronic ankle instability were included in the study. Construct validity was evaluated with correlations between the CAIT-T, Turkish version of Foot Ankle Ability Measure (FAAM-T), and Numeric Rating Scale. CAIT-T was completed twice by each participant at 7 to 10 days intervals to assess test-retest reliability based on the intraclass correlation coefficient, whereas Cronbach alpha evaluated internal consistency. Discriminative validity and content validity of the CAIT-T also evaluated. RESULTS: In construct validity, strong positive correlation was found between CAIT-T and Numeric Rating Scale perceived ankle instability (rho = -.771, P < .001), as well as moderate negative correlations with FAAM-T-activities of daily living and FAAM-T-sports (rho = -.448, P < .001 and rho = -0.541, P < .001, respectively). The CAIT-T demonstrated strong test-retest reliability (intraclass correlation coefficient score of .98) with a good internal consistency (Cronbach α: .85). Receiver operating characteristic curve showed a cutoff score of 26.5 (Youden index: 0.78, sensitivity: 0.57, specificity: 0.90.5). No ceiling or floor effects were observed. CONCLUSIONS: CAIT-T is a valid and reliable questionnaire for the assessment of chronic ankle instability in the Turkish athletic population.

Additionally, verteporfin interferes with Yes-associated protein 1 (YAP)/Transcriptional coactivator with PDZ-binding motif - TEA domain (TAZ-TEAD) pathway, thus inhibiting the downstream effect of these oncogenes and reducing the malignant properties of GBM. Animal studies have shown verteporfin to be successful in increasing survival rates, which have led to the conduction of phase 1 and 2 clinical trials to further investigate its efficacy in treating GBM. In this article, we aimed to review the novel mechanism of verteporfin's action, the impact of its interaction with YAP/TAZ-TEAD, its effect on glioblastoma stem cells, and its role in inducing ferroptosis.Article Citation - WoS: 1Citation - Scopus: 1The Relationship Between Stress, Anxiety, and Depression Levels and Pseudobulbar Affect in Patients With Multiple Sclerosis(Routledge Journals, Taylor & Francis Ltd, 2022) Ozer, Duygu; Ata, Elvan Emine; Dikec, Gul; Demir, SerkanBackground Pseudobulbar affect (PBA) has recently been added to the list of mental disorders commonly observed in patients with Multiple Sclerosis (MS). The emotional changes experienced by MS patients may be associated with other mental problems and adversely affect disease prognosis. However, there are limited studies in the international and national literature on this subject. Aim This study aimed to evaluate the relationship between PBA and stress, anxiety, and depression levels in patients with MS. Design This is a descriptive, relational, and cross-sectional study. Methods A total of 442 MS patients followed in the neurology outpatient clinic of a hospital and registered with the MS Society in Turkey participated in this study. Data were collected using a personal information form, the Turkish version of the Center for Neurologic Study-Lability Scale (CNS-LS), and the Depression Anxiety Stress Scale (DASS). Results In this study, 63.3% of the patients had PBA, 21% had extremely severe depression, 41.6% had extremely severe anxiety, and 24.9% had severe stress. Correlation analysis revealed weak positive correlations between CNS-LS total score and DASS subscale and total scores. Depression, anxiety, and stress levels accounted for 22.5% of the variation in CNS-LS total score. Conclusion The results of this study indicate that a majority of MS patients in Turkey experience PBA, depression, anxiety, and stress, and that PBA is positively associated with depression, anxiety, and stress. Impact statement This study, indicates that should be increased consultation-liaison psychiatry services in Turkey, and MS patients should benefit from comprehensive psychiatric services.
