Immune responses to SARS-CoV-2 in sub-Saharan Africa and western Europe: a retrospective, population-based, cross-sectional study.

Background: SARS-CoV-2 has been associated with a higher proportion of asymptomatic infections and lower mortality in sub-Saharan Africa than high-income countries. However, there is currently a lack of data on cellular immune responses to SARS-CoV-2 in people living in Africa compared with people in high-income regions of the world. We aimed to assess geographical variation in peripheral and mucosal immune responses.

Expression of miR-155 and CEA and VEGF Proteins as Diagnostic Markers in Early Stages of Non-Small Cell Lung Cancer in Peripheral Blood.

Background: Cancer is a disease caused by manifestation and abnormal gene expression. Many of the genes that inhibit cancer by the microRNAs. The aim of this study was to investigate the Expression of miR155 gene and CEA and VEGF proteins as Diagnostic Markers in Early Stages of Non-Small Cell Lung Cancer (NSCLC).
