  1. 1. Human cytokeratins - their use as targets in cancer management

    Author : Birgitta Sundström; Karlstads universitet.; Umeå universitet.; [1990]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicin; Biomedical Science; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Abstract : Cytokeratins, biochemically related to intermediate filaments (IF), form an intracellular network of filaments which contributes to the mechanical stabilizing of the cell. 19 individual polypeptides, divided into two groups, constitute the cytokeratin family. READ MORE

  2. 2. Colorectal cancer and radiation response The role of EGFR, AKT and cancer stem cell markers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sara Häggblad Sahlberg; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colorectal cancer; radiation; AKT; EGFR; cancer stem cells; CD133; CD44; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Abstract : The primary treatment for colorectal cancer is surgery. Radiotherapy and chemotherapy, sometimes combined, are also frequently used to diminish recurrence risk. In response to radiation exposure, several cellular signaling cascades are activated to repair DNA breaks, prevent apoptosis and to keep the cells proliferating. READ MORE

  3. 3. Radiation response in human cells DNA damage formation, repair and signaling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ann-Sofie Gustafsson; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionizing radiation; heat-labile sites; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. READ MORE

  4. 4. On microchannel acoustophoresis - Experimental considerations and life science applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Per Augustsson; Lund University.; Lunds universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microtechnology; microfluidics; lab on a chip; separation; acoustophoresis; ultrasound; acoustic resonance; acoustic radiation force; phage display; circulating tumour cells; acoustofluidics;

    Abstract : This thesis presents experimental studies of microchannel acoustophoresis, a technique for manipulation of microscopic objects in suspension by means of acoustic radiation forces induced by ultrasonic standing wave fields. By arranging an acoustic resonance across the width of a microchannel, the path of individual cells or microparticles can be deflected orthogonally to the fluid flow. READ MORE

  5. 5. On acoustic particle and cell manipulation in microfluidic systems

    University dissertation from Department of Electrical Measurements, Lund University

    Author : Filip Petersson; Lund University.; Lunds universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medicin människa och djur ; Natural science; Naturvetenskap; Technological sciences; Teknik; acoustic particle manipulation standing wave; acoustic radiation force; laminar flow; Medicine human and vertebrates ; microparticles; ultrasound; lab-on-a-chip; µ-TAS; separation; cells; microfabrication; microtechnology; microfluidics;

    Abstract : The combination of laminar flows in microfabricated channels and acoustic forces induced in ultrasonic standing wave fields offers new possibilities for advanced particle and cell manipulation in lab-on-a-chip applications as well as in relatively high throughput applications. Acoustic particle manipulation systems can be used e.g. READ MORE
