  1. 11. Ultra wideband microwave hyperthermia for brain cancer treatment

    Författare :Massimiliano Zanoli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultra wideband; treatment planning; brain cancer; applicator design; time reversal; microwave hyperthermia;

    Sammanfattning : Despite numerous clinical trials demonstrating that microwave hyperthermia is a powerful adjuvant modality in the treatment of cancers, there have been few instances where this method has been applied to brain tumors. The reason is a combination of anatomical and physiological factors in this site that require an extra degree of accuracy and precision in the thermal dose delivery. LÄS MER

  3. 12. Aspects of Electrical Bioimpedance Spectrum Estimation

    Författare :Farhad Abtahi; Kaj Lindecrantz; Fernando Seoane; Mart Min; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Bioimpedance Spectroscopy; Thoracic Bioimpedance Spectroscopy; Sub-Nyquist Sampling; Undersampling; Aliasing in Electrical Bioimpedance; Bioimpedance Estimation Error.; Medicinsk teknologi; Medical Technology; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Electrical bioimpedance spectroscopy (EBIS) has been used to assess the status or composition of various types of tissue, and examples of EBIS include body composition analysis (BCA) and tissue characterisation for skin cancer detection. EBIS is a non-invasive method that has the potential to provide a large amount of information for diagnosis or monitoring purposes, such as the monitoring of pulmonary oedema, i. LÄS MER

  4. 13. Epigenetic Regulation of Replication Timing and Signal Transduction

    Författare :Rosita Bergström; Aristidis Moustakas; Carl-Henrik Heldin; Rolf Ohlsson; Alain Mauviel; Uppsala universitet; []
    Nyckelord :Cell and molecular biology; Chromatin; CTCF; Epigenetics; Genomic Imprinting; H19; Id; Igf2; Insulator; Replication; Signal Transduction; Smad; TGF-β; Transcription; Cell- och molekylärbiologi;

    Sammanfattning : Upon fertilization the paternal and maternal genomes unite, giving rise to the embryo, with its unique genetic code. All cells in the human body are derived from the fertilized ovum: hence they all contain (with a few exceptions) the same genetic composition. LÄS MER

  5. 14. Smartware electrodes for ECG measurements : Design, evaluation and signal processing

    Författare :Linda Rattfält; Per Ask; Fredrik Björefors; Kaj Lindecrantz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of this thesis work has been to study textile and screen printed smartware electrodes for electrocardiographic (ECG) measurements both in terms of their electrode properties and possibility to further improve their robustness to movement induced noise by using signal processing. Smartware electrodes for ECG measurements have previously been used in various applications but basic electrical electrode properties have not sufficiently been looked into. LÄS MER

  7. 15. Apolipoprotein M – Studies of Structure and Function

    Författare :Josefin Ahnström; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal peptidase; signal peptide; crystallization; Apolipoprotein; lipocalin; HDL; coronary heart disease;

    Sammanfattning : Apolipoprotein M (apoM), a 25 kDa plasma protein, is found in all major lipoprotein classes, although the majority is found in high density lipoproteins (HDL). ApoM has been suggested to be involved in the formation of and adding to the antiatherogenic functions of HDL, but its function is still not completely known. LÄS MER
