Novel coronavirus disease 2019 (COVID-19) has become a public health concern with over 6.5 million cases and 390,000 deaths around the world. This research aimed to find an association between computed tomography (CT) scores and clinical and laboratory findings to estimate the extent of lung infection in patients with COVID-19. The study sample enrolled 129 patients diagnosed with COVID-19 from January to February 2020. The chest CT images and clinical data were reviewed, images were segmented and scored by the degree of involvement from 0 to 4, and the relationship between them and clinical and laboratory findings were analyzed statistically. This study included 74 men and 59 women with a mean age of 55.08 years. Different abnormalities were observed; the mean CT score was 8.52 (7.83 to 9.21) and the most frequent lesions were GGO and consolidation. Our results revealed significant differences between groups categorized by dyspnea, sore throat, and low oxygen saturation concerning CT scores. There was also a significant correlation between CT scores and WBC counts and CRP levels (P

Background and Objectives: The detection of Ureaplasma urealyticum is usually done through culture. With the change of the smallest effective factor inculture, we face the lack of growth of these bacteria, which is one of the important reasons to find a suitable alternative for the diagnosis of this bacterium. UreDis a protected gene in this bacterium. The aim of this was to evaluate the ability of antigenic regions of UreD protein to bind to patients' serum antibodies. Materials and Methods: Antigenic regions of UreD protein were predicted using IEDB software with five different meth- ods: Emini Surface Accessibility Prediction, Kolaskar and Tongaonkar Antigenicity, Chou and Fasman beta turn prediction, Karplus and Schulz flexibility scale, Ellipro –Epitope predictionbased upon structural protrusion. Antigenic regions of UreD gene was clonned, expressed and purified. The antigenicity of this recombinant protein against theantibodies in the serum of people infected with U. urealyticum infections was checked in western blotting. Results: The results showed that the antigenic regions of the UreD protein was producted and its antigenicity was demon- strated in western blotting.Moreover, all sera from patients infected with U. urealyticum reacted to the recombinant antigen. Conclusion: Specimens from people infected with U.urealyticum infection was positive in Western blotting suggesting that UreD protein has antigenic properties. Therefore, it can be used as a suitable candidatefor the design of diagnostic kits and U. urealyticum vaccine.
