  4. 2. Towards Heart Rate Variability Tools in P-Health : Pervasive, Preventive, Predictive and Personalized

    Author : Farhad Abtahi; Kaj Lindecrantz; Birgitta Janerot Sjöberg; Fernando Seoane; Annette Bruchfeld; Metin Akay; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart Rate Variability; Cholinergic Anti-inflammatory Pathway; Autonomic Nervous System; Vagal activity; Biofeedback; Gamification; Serious Gaming; Inflammatory Markers; Raspberry PI; Medical Technology; Medicinsk teknologi;

    Abstract : Heart rate variability (HRV) has received much attention lately. It has been shown that HRV can be used to monitor the autonomic nervous system and to detect autonomic dysfunction, especially vagal dysfunction. Reduced HRV is associated with several diseases and has also been suggested as a predictor of poor outcomes and sudden cardiac death. READ MORE

  5. 3. Advancing Upconversion Emissions for Biomedical Imaging

    Author : Haichun Liu; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; upconverting nanoparticles; luminescence; fluorescence; inverse problem; biomedical optics; biomedical imaging; photon migration; upconversion; tomography; saturation; Fysicumarkivet A:2014:Liu;

    Abstract : During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical applications.

  6. 4. High-resolution biomedical phase-contrast tomography

    Author : William Twengström; Hans Hertz; Anna Burvall; Marco Stampanoni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; x-ray; x-ray imaging; biomedical; phase contrast; tomography; zebrafish; coronary artery; virtual histology; ring artifacts; phase retrieval; mummy; Fysik; Physics;

    Abstract : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. READ MORE

  7. 5. Aligning and Merging Biomedical Ontologies

    Author : He Tan; Patrick Lambrix; Nahid Shahmehri; Bo Servenius; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ontologies; Ontology engineering; Biomedical ontologies; Ontology alignment; Ontology alignment; Ontology merging; Information technology; Informationsteknik;

    Abstract : Due to the explosion of the amount of biomedical data, knowledge and tools that are often publicly available over the Web, a number of difficulties are experienced by biomedical researchers. For instance, it is difficult to find, retrieve and integrate information that is relevant to their research tasks. READ MORE
