Clinical implementation of a fully automated quantitative perfusion cardiovascular magnetic resonance imaging workflow with a simplified dual-bolus contrast administration scheme.

This study clinically implemented a ready-to-use quantitative perfusion (QP) cardiovascular magnetic resonance (QP CMR) workflow, encompassing a simplified dual-bolus gadolinium-based contrast agent (GBCA) administration scheme and fully automated QP image post-processing. Twenty-five patients with suspected obstructive coronary artery disease (CAD) underwent both adenosine stress perfusion CMR and an invasive coronary angiography or coronary computed tomography angiography. The dual-bolus protocol consisted of a pre-bolus (0.

Testing for COVID-19 is performed curatively for disease detection and as screening tool to prevent spread for public health and infection prevention. Testing for access is an important additional measure to provide information about asymptomatic or pre-symptomatic infection. In a recent meta-analysis 42.

KCl-Extractable surface antigens of Schistosoma mansoni: immunological characterization and applicability in immunodiagnosis.

A Schistosoma mansoni antigen preparation was obtained by extraction of adult worms with a 3 M KCl solution. An indirect immunofluorescence reaction on cryostat sections of adult worms showed that the extracted antigens mainly originated from the tegument. The complex antigenic composition of the tegument extract was shown by immunoelectrophoresis against serum from infected mice and immunized rabbits, which gave up to 9 and 17 precipitation lines, respectively.
