  2. 16. Predictive and prognostic factors in cervical carcinomas treated with (chemo-) radiotherapy

    Author : Louise Bohr Mordhorst; Bengt Sorbe; Preben Kjölhede; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical carcinoma; radio-chemotherapy; biomarkers; predictive factors; prognostic factors; multiprotein analysis; Hedgehog pathway; Wnt β-catenin pathway; Surgery; Kirurgi;

    Abstract : A series of 131 women with cervical carcinoma FIGO stage I-IV were treated with external radiotherapy and intracavitary brachytherapy. In 47 patients (36%) concomitant chemotherapy was given. One hundred and twenty-one tumors (92%) achieved complete remission. Addition of chemotherapy increased primary cure rate to 98%. READ MORE

  4. 17. Crosslinking of Ethylene Copolymers

    Author : Magnus Palmlöf; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dibutyltindilaurate; crosslinking; water; ethylene diene copolymers; peroxide; polyethylene; electron beam; crosslinking density; ethylene vinylsilane copolymers;

    Abstract : The chemical reactions taking place when crosslinking poly(ethylene-co-vinyltrimethoxysilane) (EVS) have been studied. Films of EVS were stored in water at 90 °C or treated at processing temperatures in a tubular oven. The different chemical groups involved in the reactions were then followed by FTIR after different treatment times. READ MORE

  5. 18. Exploring phenomena that affect the fate and impact of radioactive materials in the blue mussel

    Author : Benedict Jaeschke; Clare Bradshaw; Andrew Turner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radioecology; ionising radiation; environmental protection; Mytilus edulis; bioaccumulation; dose-response; ecotoxicology; tritium; particle; hypoxia; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Current protection of the marine environment from radiation is based largely on measuring, estimating and modelling accumulation and impact(s) of radionuclides in a few marine species. Using a relevant marine organism, this thesis focusses on investigating some poorly described phenomena that could cause deviations from predicted measurements. READ MORE

  6. 19. Optimizing experimental radioimmunotherapy : investigating the different mechanisms behind radiation induced cell deaths

    Author : Theres Lindgren; David Eriksson; Torgny Stigbrand; Bo Stenerlöw; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitotic catastrophe; senescence; cell cycle checkpoint; apoptosis; radiation; gene expression; p53; immunologi; Immunology; radiofysik; radiation physics;

    Abstract : Background. Radiation therapy is an important treatment regimen for malignant disease. Radiation therapy uses ionizing radiation to induce DNA damage in tumor cells in order to kill them. READ MORE

  7. 20. Mimicking the Binary World: Photochromic Compounds in Molecular Logic

    Author : Martin Hammarson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA; dithienylethene; molecular logic; spiropyran; photochromism; porphyrin;

    Abstract : The language of the binary world is used in, e.g., electronic circuits of a computer where a signal either can be on, known as 1 or off, known as 0. In the effort to make things smaller, molecules that mimic this binary world have been suggested as potential replacements for electronic circuits. READ MORE
