  1. 16. Brownian Relaxation Measurements of Magnetic Nanoparticles: Towards the Development of a Novel Biosensor System

    Författare :Andrea Prieto Astalan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PSA; Magnetic susceptibility; Brownian relaxation; Biosensor; Prostate specific antigen; Magnetic nanoparticles; Frequency domain; Induction coils; Time domain;

    Sammanfattning : Magnetic measurements of the Brownian relaxation time of thermally blocked magnetic nanoparticles dispersed in a solution have been performed in order to determine the hydrodynamic size distribution of the particles. By measuring changes in the hydrodynamic size of the particles, the ammount of analytes attached to the surface of particles can be determined. LÄS MER

  3. 17. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

    Författare :Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Sammanfattning : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. LÄS MER

    Sammanfattning : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. LÄS MER

  7. 20. Tertiary lymphoid structures in glioblastoma : Discovery, Characterization and Therapeutic Induction

    Författare :Alessandra Vaccaro; Anna Dimberg; Victor Engelhard; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tertiary lymphoid structures; Glioma; Glioblastoma; Immunotherapy; Immunologi; Immunology; Oncology; Onkologi;

    Sammanfattning : Glioblastoma (GBM) is an incurable brain cancer with a median survival of less than two years from diagnosis. The tumor microenvironment plays a major role in GBM progression through sustaining immunosuppression and poor lymphocytic infiltration. LÄS MER
