The scale for the perception of artistic sides of the teaching profession: a scale development study: Perception of artistic sides of teaching profession

This study aims to develop a measurement tool that can reveal the perceptions of teachers about the artistic sides of their profession. In the study, data were collected from two different groups for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to determine the construct validity of the scale. There are 442 people in the first study group, consisting of preschool, primary, secondary and high school teachers, and 511 people in the second study group. As a result of EFA, it was determined that the scale had a structure with three factors and 31 items. The variance rate explained by these factors is 67.9%. This construct was validated by DFA. Goodness of fit indices calculated by CFA are as follows: χ²/sd= 3.887; CFI=.912; TLI=.903, RMSEA=.068; SRMR=0.072. The Cronbach's Alpha internal consistency coefficient of the scale is .96. As a result, a valid and reliable data collection tool has been developed that can give an idea about how teachers perceive the artistic sides of their profession

Cobalt(II)/(III) complexes bearing a tetradentate thiosemicarbazone: Synthesis, experimental and theoretical characterization, and electrochemical and antioxidant properties

New cobalt complexes,Co1andCo2, were synthesized starting from acetylacetone-S-methylthiosemicarbazone. The square planar cobalt(II) and octahedral cobalt(III) complexes were characterized by FT-IR, UV-visible,H-1 NMR, and X-ray diffraction spectroscopies and mass spectrometry. Frontier orbitals of the complexes were theoretically obtained to better understand the complex structures and intermolecular interactions. The electrochemical behaviors ofCo1andCo2were investigated and the results were evaluated by comparing with each other and with similar published compounds to determine their possible usage in various electrochemical technologies, such as energy storage devices, electrocatalysts, and electrosensors. Metal-based oxidation at around 0 V and metal-based reduction at around -1.0 V indicated that these complexes are valuable for the proposed applications. By determining the trolox equivalent antioxidant capacity and the radical scavenging activity of the cobalt complexes, the compatibility between the antioxidant qualification, redox, and theoretical calculation results was discussed

Background: Aboveground parts and bulbs of Ornithogalum species are consumed as food and used in traditional medicine in worldwide. Objective: It is aimed to report the antioxidant capacity and phenolic compounds content of Ornithogalum sigmoideum, Ornithogalum orthophyllum and Ornithogalum oligophyllum for the first time. Materials and methods: Antioxidant activity of the crude methanol extracts of the aerial parts and the bulbs of the species were determined with 1,1-diphenyl-2-picryl-hydrazyl, superoxide radical scavenging, ferrous ion-chelating effect, phosphomolybdenum-reducing antioxidant power and ferric-reducing antioxidant power assay. The ethylacetate, diethylether and water subextracts from leaf and flower were analyzed to quantify selected phenolic compounds by HPLC-UV. Results: Among the six extracts, the methanol extract of the aerial parts of O. orthophyllum contained the highest amount of phenolic compounds (GAE, 11.0 mg/g extract). The aerial parts of O. orthophyllum showed higher DPPH and SOD activities than the other extracts with the SC50 values of 0.39 ± 0.05 mg/mL and 0.44 ± 0.08 mg/mL, respectively. Protocatechuic acid, p-hydroxybenzoic acid, vanillic acid and p-coumaric acid were the most abundant compounds at all the subextracts. Conclusion: The antioxidant activity is found to be in accordance with the levels of phenolic content in the extracts.Geçmiş: Ornithogalum türlerinin topraküstü kısımları ve soğanları, dünya çapında gıda olarak tüketilmekte ve halk ilacı olarak kullanılmaktadır. Ornithogalum sigmoideum, Ornithogalum orthophyllum ve O. oligophyllum türlerinin daha önce çalışılmamış olan antioksidan kapasite ve fenolik bileşiklerini sunmak amaçlanmıştır. Yöntem ve Gereçler: Türlerin toprak üstü kısımları ve soğanlarının ham metanol ekstrelerinin antioksidan aktiviteleri 1,1-difenil-2-pikril-hidrazil, süperoksit radikal süpürücü, demir iyon-şelat etkisi, fosfomolibdenyum indirgeyici antioksidan güç, demir indirgeyici antioksidan güç yöntemleriyle araştırılmıştır.

Lung cancer from suspicion to treatment: An indicator of healthcare access in Turkey

Background: Lung cancer is the leading cause of cancer-related deaths worldwide. Before beginning lung cancer treatment, it is necessary to complete procedures such as suspecting lung cancer, obtaining a pathologic diagnosis, and staging. This study aimed to investigate the processes from suspicion of lung cancer to diagnosis, staging, and treatment initiation. Methods: The study was designed as a multicenter and cross-sectional study. Patients with lung cancer from various health institutions located in all geographic regions of Turkey were included in the study. The sociodemographic and clinical characteristics of the patients, the characteristics of the health institutions and geographic regions, and other variables of the lung cancer process were recorded. The time from suspicion of lung cancer to pathologic diagnosis, radiologic staging, and treatment initiation, as well as influencing factors, were investigated. Results: The study included 1410 patients from 29 different medical centers. The mean time from the initial suspicion of lung cancer to the pathologic diagnosis was 48.0 ± 52.6 days, 39.0 ± 52.7 days for radiologic staging, and 74.9 ± 65.5 days for treatment initiation. The residential areas with the most suspected lung cancer cases were highly developed socioeconomic zones. Primary healthcare services accounted for only 0.4% of patients with suspected lung cancer. The time to pathologic diagnosis was longer in the Marmara region, and the wait time for staging and treatment initiation was longer in Eastern and Southeastern Anatolia. Patients who presented to chest disease referral hospitals with peripheral lesions, those with early-stage disease, and those who were diagnosed surgically had significantly longer wait times. Conclusion: The time between pathologic diagnosis, staging, and treatment initiation in lung cancer was longer than expected. Increasing the role of primary healthcare services and distributing socioeconomic resources more equally will contribute to shortening the time to diagnosis and improve treatment processes for lung cancer

Re-examining the characteristics of pediatric multiple sclerosis in the era of antibody-associated demyelinating syndromes.

Background: The discovery of anti-myelin oligodendrocyte glycoprotein (MOG)-IgG and anti-aquaporin 4 (AQP4)-IgG and the observation on certain patients previously diagnosed with multiple sclerosis (MS) actually have an antibody-mediated disease mandated re-evaluation of pediatric MS series. Aim: To describe the characteristics of recent pediatric MS cases by age groups and compare with the cohort established before 2015. Method: Data of pediatric MS patients diagnosed between 2015 and 2021 were collected from 44 pediatric neurology centers across Turkiye. Clinical and paraclinical features were compared between patients with dis-ease onset before 12 years (earlier onset) and >= 12 years (later onset) as well as between our current (2015-2021) and previous (< 2015) cohorts. Results: A total of 634 children (456 girls) were enrolled, 89 (14%) were of earlier onset. The earlier-onset group had lower female/male ratio, more frequent initial diagnosis of acute disseminated encephalomyelitis (ADEM), more frequent brainstem symptoms, longer interval between the first two attacks, less frequent spinal cord involvement on magnetic resonance imaging (MRI), and lower prevalence of cerebrospinal fluid (CSF)-restricted oligoclonal bands (OCBs). The earlier-onset group was less likely to respond to initial disease-modifying treatments. Compared to our previous cohort, the current series had fewer patients with onset < 12 years, initial presentation with ADEM-like features, brainstem or cerebellar symptoms, seizures, and spinal lesions on MRI. The female/male ratio, the frequency of sensorial symptoms, and CSF-restricted OCBs were higher than reported in our previous cohort. Conclusion: Pediatric MS starting before 12 years was less common than reported previously, likely due to exclusion of patients with antibody-mediated diseases. The results underline the importance of antibody testing and indicate pediatric MS may be a more homogeneous disorder and more similar to adult-onset MS than previously thought
