MicroCT Imaging of Heart Valve Tissue in Fluid.

Background: Heart valve computational models require high quality geometric input data, commonly obtained using micro-computed tomography. Whether in the open or closed configuration, most studies utilize dry valves, which poses significant challenges including gravitational and surface tension effects along with desiccation induced mechanical changes.

Objective: These challenges are overcome by scanning in a stress-free configuration in fluid.

[Evaluation of the erythrocyte antibody registry in East Germany (1978-1980)].

On the basis of statistics on erythrocyte antibodies annually transmitted to the Ministry of Health by the institutions of blood transfusion service in the GDR, an analysis on frequency, population and distribution of specificity to be found in erythrocyte antibodies was established for the first time from 1978 to 1980. For the time covered by the investigation, the GDR percentage of the total detection rate for antibodies amounted to 0.39%, with a fluctuating range of 0.
