Perceived quarantine competence, attitudes and practices among the public during the coronavirus pandemic: A Saudi descriptive study.

Background: The unavailability of data on the long-term efficacy of COVID-19 vaccines and of effective specific treatment, in addition to the emergence of new COVID-19 variants, makes nonpharmaceutical measures a mainstay for preventing the spread of infection. The policy responses of governments to the pandemic should be integrated with public behavioral changes. This study examines public attitudes, practices and perceived quarantine competency in Saudi Arabia during the COVID-19 pandemic.

Quality assurance of test blueprinting.

Tests offer scores that measure student learning and programs outcomes. Valid examinations are needed to accurately reflect scores related to dimensions of knowledge, analysis and different competencies in health education. The primary step in the process of exam development should be the construction of a test blueprint.

Identification of murine T-cell epitopes on low-molecular-mass secretory proteins (CFP11, CFP17, and TB18.5) of Mycobacterium tuberculosis.

The low-molecular-mass secretory proteins of Mycobacterium tuberculosis have been shown to be major T-cell antigens during infection with the pathogenic bacterium. In this study, we determined murine T-cell epitopes on three low-molecular-mass proteins, CFP11 (Rv2433c), CFP17 (Rv1827), and TB18.5 (Rv0164) using DNA immunization of inbred mice.

Characterization of murine T-cell epitopes on mycobacterial DNA-binding protein 1 (MDP1) using DNA vaccination.

Mycobacterial DNA-binding protein 1 (MDP1) is a major protein antigen in mycobacteria and induces protective immunity against Mycobacterium tuberculosis infection in mice. In this study we determined murine T-cell epitopes on MDP1 with MDP1 DNA immunization in mice. We analyzed interferon-gamma production from the MDP1 DNA-immune splenocytes in response to 20-mer overlapping peptides covering MDP1 protein.
