DETERMINING THE COGNITIVE STRUCTURES AND MISCONCEPTIONS ABOUT CHROMOSOME AND HOMOLOGOUS CHROMOSOME CONCEPTS IN HIGH SCHOOL STUDENTS: DRAWING-WRITING TECHNIQUE

This study aims to determine the cognitive structures related to the chromosome and homologous chromosomes as well as the misconceptions of 10th-grade high school students. 140 10th-grade high school students participated in the study. Data were collected using the drawing-writing technique. The students were asked to draw the chromosome and homologous chromosomes separately, to identify their elements, and to write an explanatory sentence about these concepts. The drawings and explanations were analyzed separately and the students’ cognitive structures and misconceptions were investigated. The analyses revealed students have misconceptions about the chromosome and homologous chromosomes. The study results emphasize that effectively teaching the concept of chromosome and homologous chromosomes; the basic concept of the cell cycle, is fundamental for further science studies.  Article visualizations

Some Observations on Basra Province and Persian Gulf Under the Ottoman Rule in 19th Century

Basra Province and Persian Gulf were geopolitically significant in 19th century as it is in today’s world. In this research, the importance of this region is explained in lights of Prime Ministery Ottoman Archives and Basra Province Yearbooks. Basra, which was governed as province or sanjak until 1884, became a province consisted of Müntefik, Amâre and Necid sanjaks except being central sanjak in this date. By utilizing the information about Basra in written statements (layihas) of Mutasarrıf Hasan Pasha who worked there in 1880, some evaluation about the region is tried to be stated

Evaluation of Clinical and Laboratory Findings of COVID-19 Patients with Dermatological Involvements: A Single-Center Retrospective Cross-Sectional Study

Introduction: Cutaneous manifestations of the coronavirus disease-2019 (COVID-19) are increasingly reported, with their incidence and pathophysiological mechanisms yet to be clarified. The aim of this study was to evaluate COVID-19 patients presenting with dermatological involvement. Materials and Methods: COVID-19 patients with dermatological involvements followed up in a single tertiary center between August 2020 and August 2021 were assessed in terms of demographic characteristics, clinical and laboratory findings, and treatment methods. Results: A total of 65 patients (female:male ratio= 0.4:1, mean age= 59.7 ± 18.2 years) were evaluated. The dermatological involvements due to COVID-19 were maculopapular rash (n= 49, 75.4%), urticaria (n= 9, 13.8%), herpes zoster (HZ) (n= 6, 9.2%), and pernio (n= 1, 1.5%). In COVID-19 patients with dermatological involvements pulmonary involvement rate was 96.9%. The most common accompanying symptoms were anosmia (n= 47, 72.3%) and ageusia (n= 43, 66.2%), The mean time between the first COVID-19 symptom and the onset of dermatological involvement was 3.3 ± 1.2 days, and the mean time to regression of the lesions was 3.2 ± 1.8 days. Conclusion: Anosmia, ageusia, and pulmonary involvement were common findings especially in patients with maculopapular rash and HZ, probably due to increased inflammation and cytokine storm. The assessment of anosmia and ageusia, especially in patients presenting with maculopapular rash and HZ, may help early recognition of COVID-19 cases. In addition, it should be predicted that individuals with this combination may have a higher risk of pulmonary involvement and disease severity and necessary precautions should be taken during the early stages

Laboratory Acquired Brucellosis in Turkey

Background Laboratory healthcare workers (HCWs) are at risk of laboratory-acquired brucellosis (LAB). Aim To describe the risk factors of LAB among HCWs. Methods A multicentre survey study was conducted by face-to-face interview in 38 hospitals from 17 provinces of Turkey. A structured survey was administered to the HCWs, working in infectious diseases clinics and microbiology departments, who were at risk of brucella infection. Findings The survey response rate was 100%. Of the 667 laboratory workers, 38 (5.8%) had a history of LAB. In multivariate analysis, factors independently associated with an increased risk of LAB included working with the brucella bacteria (odds ratio: 5.12; 95% confidence interval: 2.28&ndash;11.52; P&nbsp;&lt;&nbsp;0.001) and male gender (2.14; 1.02&ndash;4.45; P&nbsp;=&nbsp;0.042). Using a biosafety cabinet level 2 (0.13; 0.03&ndash;0.60; P&nbsp;=&nbsp;0.009), full adherence to glove use (0.27; 0.11&ndash;0.65; P&nbsp;=&nbsp;0.004) and longer duration of professional life (0.86; 0.80&ndash;0.92; P&nbsp;&lt;&nbsp;0.001) were found to be protective. Conclusions Working with the brucella bacteria, being male, a lack of compliance with personal protective equipment and biosafety cabinets were the independent risk factors for the development of LAB in our series. Increased adherence to personal protective equipment and use of biosafety cabinets should be priority targets to prevent LAB.</p
