Distribution of pslA among Local Isolates of Biofilm- Producing Pseudomonas aeruginosa
...Show More Authors

16S rRNA gene sequence examination is an effective instrument for characterization of new pathogens in clinical specimens. Akey component of colonization, biofilm formation, and protection of the pragmatic human pathogen Pseudomonasaeruginosais the biosynthesis of the exopolysaccharide Psl.Extracellular polysaccharides,biofilm, are secreted by microorganisms into the neighboring environment and are significant for surface attachment and keeping structural safety within biofilms.Biofilm production is an important technique for the survival of P. aeruginosa,and its association with antimicrobial resistance represents a defy for patient therapeutics. The aim of the current research is to assess the antibiotic resistance manner and distribution of the pslA gene among biofilm producingP. aeruginosa isolates, which have beengained from some hospitals in Baghdad, Iraq. Twenty-five P. aeruginosa isolates were obtained fromDepartment of Biology, College of Science, University of Baghdad. TheP. aeruginosa isolates were recognized using standard bacteriological techniques. Drug susceptibility test was done by disk diffusion technique for all the isolates against five antimicrobial agents.DNA was extracted from twenty-fiveP. aeruginosa isolates, which were selected as being resistant to gentamicin using the polymerase chain reaction(PCR). A specific primer pair was used to amplify 16S rRNA by a conventional PCR technique. Biofilm development was measured by microtiter plate test. The results of 16S rRNA showed that all 25 selected isolates were resistant to gentamicin harbored this gene. Biofilm formation was observed in 24/25(96%) of the P. aeruginosa isolates. The possibility of biofilm formation was remarkablyrelatedtothe resistance to gentamicin. In addition, the pslA gene was existed in all biofilm and non-biofilm producing the selected isolates with a frequency of 100% (n = 25).16S rRNA sequencing can be used to identify genetically atypical P. aeruginosa isolates from different origins. Theresults of the currentresearch well clarified that the P. aeruginosa biofilm-forming isolates were more resistant to the tested antibiotics. What is more, because of wide spreading, it appears that the pslA gene is associated with biofilm formation.

The Impact of a Counseling Program with a Cognitive Reconstruction Method on the Development of the Psychological Hardness among Middle School Students
...Show More Authors

The current research aims to determine the impact of the cognitive reconstruction program on the development of psychological hardness among middle school students through the experimental verification of three hypotheses. The research sample consisted of (16) out of (450) students selected from Ibn Rushud preparatory school- Al-Rusafa 2. These participants have been randomly distributed into two equal groups. The researcher has used the method of cognitive reconstruction with the experimental group, whereas with the controlling group, he used nothing. The researcher has further used the scale of psychological hardness of Kobassa with the participants; the scale has been built in a way that suits the sample of the study, which consisted

Evaluating the Diagnostic Proficiency Among a Sample of Final Stage Dental Students in Some Orthodontic Cases: A Comprehensive Analysis of Clinical Competence
...Show More Authors

Background/Objectives: This study evaluates the diagnostic and referral skills of final-year dental students at Al-Iraqia University using a questionnaire based on malocclusion cases ranging from mild to severe. Methods: The questionnaire, featuring photos and radiographs of five selected treated cases from two textbooks, was answered by 165 students who were asked to assess each case and determine whether orthodontic or surgical treatment was necessary, as well as to identify factors contributing to an unesthetic profile, such as irregular teeth. Frequency distribution and the Chi-square test were used for statistical analysis. Results: The results indicated good overall clinical competence. The unesthetic profile and irregular tee

Expression level of non-coding (MiR-155) gene as biomarker for severity of coronaviruses infection among vaccinated and non-vaccinated Iraqi patients
...Show More Authors

BACKGROUND: The COVID-19 pandemic caused by SARS-CoV-2 is influenced by genetic and epigenetic factors, including miR-155, which affects immune cell and virus functions and laboratory biomarkers. OBJECTIVE: To evaluates miR-155’s role as a biomarker for SARS-CoV-2 detection and monitoring, examining its significance in identifying infection in both vaccinated and unvaccinated individuals using ROC curve analysis. METHODS: Blood samples were collected from 70 patients who attended Medical City Hospital in Baghdad from June 2022 to April 2023 and were determined to be associated with SARS-CoV-2 (35 patients were hospitalized at the Intensive Care Units due to the severity of their symptoms while the other 35 were left in the hospit

E-learning applications and their significance among students of the Department of Chemistry in the Faculty of Education for Pure Sciences – Ibn Al-Haytham
...Show More Authors

--The objective of the current research is to identify: 1) Preparing a scale level for e-learning applications, 2) What is the relationship between the applications of e-learning and the students of the Department of Chemistry at the Faculty of Education for Pure Sciences/ Ibn Al-Haytham – University of Baghdad. To achieve the research objectives, the researcher used the descriptive approach because of its suitability to the nature of the study objectives. The researcher built a scale for e-learning applications that consists of (40) items on the five-point Likrat scale (I agree, strongly agree, neutral, disagree, strongly disagree). He also adopted the scale of scientific values, and it consists of (40) items on a five-point scale as wel
