  2. 11. Development of Techniques for Characterization, Detection and Protein Profiling of Extracellular Vesicles

    Author : Sara Cavallaro; Jan Linnros; Apurba Dev; Hakho Lee; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular vesicles; streaming current; fluorescence microscopy; atomic force microscopy; scanning electron microscopy; protein profiling; size profiling; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Abstract : Nanosized extracellular vesicles (EVs, ∼30-2000 nm) have emerged as important mediators of intercellular communication, offering opportunities for both diagnostics and therapeutics. In particular, small EVs generated from the endolysosomal pathway (∼30-150 nm), referred to as exosomes, have attracted interest as a suitable biomarker for cancer diagnostics and treatment monitoring based on minimally invasive liquid biopsies.

  4. 12. GC-MS based metabolomics – Development of a next generation GC-MS method and its application to nutrition and biomarker research

    Author : Otto Savolainen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gas chromatography; nutrition; biomarkers; metabolomics; mass spectrometry; type 2 diabetes;

    Abstract : Metabolomics, the measurement of a broad range of small molecules in a sample, is maturing as a field in analytical chemistry and becoming a standard research tool in biological sciences for helping to generate a wider understanding of the complex biological mechanisms behind, for example, development of disease and effects of diet on health. Metabolomics analysis is generally divided into either targeted or untargeted metabolomics. READ MORE

  5. 13. Application, Optimisation and Evaluation of Deep Learning for Biomedical Imaging

    Author : Håkan Wieslander; Carolina Wählby; Ida-Maria Sintorn; Ola Spjuth; Andreas Hellander; Bjoern Menze; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deep Learning; Microscopy; Image Analysis;

    Abstract : Microscopy imaging is a powerful technique when studying biology at a cellular and sub-cellular level. When combined with digital image analysis it creates an invaluable tool for investigating complex biological processes and phenomena. READ MORE

  6. 14. Pharmaceutical and Biomedical Applications of Spectroscopy in the Photon Migration Regime

    Author : Tomas Svensson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Porosimetry; Biomedical optics; Pharmaceutical analysis; Monte Carlo; Scattering media; Photon migration; Laser spectroscopy; High-resolution spectroscopy; Time-resolved spectroscopy; Time-of-flight;

    Abstract : The present thesis is devoted to two different matters: One part is the development of a novel optical technique for characterisation of solid pharmaceutical materials. The other part being the continued development of photon time-of-flight spectroscopy, as well as exploration of new application areas of this method. READ MORE

  7. 15. Image Filtering Methods for Biomedical Applications

    Author : M. Khalid Khan Niazi; Ewert Bengtsson; Ingela Nyström; Lucas J. van Vliet; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital image analysis; Image filtering; Intensity inhomogeneity correction; Empirical mode decomposition; Particle Swarm optimization; Image registration; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Filtering is a key step in digital image processing and analysis. It is mainly used for amplification or attenuation of some frequencies depending on the nature of the application. Filtering can either be performed in the spatial domain or in a transformed domain. READ MORE
