  1. 1. Molecular characterization of vascular malformations using single-cell RNA sequencing and immunohistological analysis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Amanda Norrén; [2023]
    Keywords : ;

    Abstract : CCM is a human disease in which vascular malformations develop in the central nervous system, predominantly in the brain. The malformations which can measure up to several centimeters in size are dilated and leaky vessels, with unstable cellular junctions and thin vessel walls. READ MORE

  3. 2. Performance Evaluation of Lumen Segmentation in Ultrasound Images

    University essay from Umeå universitet/Institutionen för datavetenskap

  6. 5. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Björn Walter; Stefan Piiroinen; [2021]
    Keywords : Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

    Abstract : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.
