background: efficient screening for detection of colorectal cancer (crc) at earlier stages reduces its mortality. the purpose of this study was to investigate expression of carcinoembryonic antigen (cea) and human telomerase reverse transcriptase (htert) mrna in peripheral blood of crc patients and to present strategies for early detection screen test. methods: twenty seven patients in non-meta...

abstract background thalassemia patients that are conventionally treated by a regular transfusion regimen are exposed to blood born viral infections.the aim of this study was to investigate the seroprevalence of hepatitis b virus (hbv), hepatitis c virus (hcv) , and human immunodeficiency virus(hiv) among all multitransfused thalassemia patients in west north of iran. material and methods a ret...

Transfusion of crossmatch-incompatible red blood cells (RBCs) can result in antibody-mediated hemolysis. However, in some patients, crossmatch-incompatible RBCs lose the incompatible antigen from their surface, and then circulate normally ("antigen loss"). Although antigen loss has been reported in the settings of autoimmune hemolytic anemia and transfusion of crossmatch-incompatible RBCs, mech...

One of the most successful strategies to halt spread COVID-19 pandemic is quickly screen by testing identify infected individuals, leading effectively isolating patients. However, in order ensure test's value, diagnostic value must be thoroughly analyzed before using it. In this research, we used a cross-sectional descriptive study evaluate efficacy Lumipulse G SARS-COV-2 Ag test on salivary an...

Early identification and isolation of SARS-CoV-2-infected individuals is central to contain the COVID-19 pandemic. Nasopharyngeal swabs (NPS) serve as a specimen for detection by RT-PCR rapid antigen screening tests. Saliva has been confirmed reliable alternative shown be valuable diagnosing children in repetitive mass testing due its non-invasive collection. Combining advantages saliva with th...

These last months, dozens of SARS-CoV-2 serological tests have become available with varying performances. A major effort was completed to compare 17 in April 2020 Switzerland. In a preliminary phase, we compared IgG, IgM, IgA and pan Ig including ELISA, LFA, CLIA ECLIA on panel 182 sera, comprising 113 sera from hospitalized patients positive RT-PCR, 69 sampled before 1st November 2019, expect...
