  2. 1. Relative biological effectiveness in proton therapy: accounting for variability and uncertainties

    Author : Jakob Ödén; Iuliana Toma-Dasu; Kjell Eriksson; Radhe Mohan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; relative biological effectiveness; linear energy transfer; proton track-end optimisation; radiation-induced toxicity; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Radiation therapy is widely used for treatments of malignant diseases. The search for the optimal radiation treatment approach for a specific case is a complex task, ultimately seeking to maximise the tumour control probability (TCP) while minimising the normal tissue complication probability (NTCP).

  5. 3. Radiation-induced apoptosis in human lymphocytes : studies on expression, function and effects of different radiation qualities

    Author : Annelie Meijer; Fabrizio Palitti; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apoptosis; clonogenic survival; growth factors; chromosomal aberrations CA ; low dose-rate LDR ; linear energy transfer LET ; relative biological effectiveness RBE ; radio sensitivity; ataxia telangiectasia A-T ; Physical Biology; fysikalisk biologi;

    Abstract : We are constantly exposed to radiation. Radiation causes damage to our cells. By the removal of damaged and unwanted cells, apoptosis is considered to be one of the most indispensable defence processes for a multi-cellular organism. READ MORE

  6. 4. Plant pathogen defense: Signalling, resistance and cell death

    Author : Oskar N. Johansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas; cell death; pathogens; plant defense; hypersensitive response; glycolipid; reactive oxygen species; blumeria graminis; erysiphe pisi;

    Abstract : Pathogenic microorganisms are present everywhere in nature and infect both animals and plants. Phytopathogenic microorganisms cause diseases on plants, and are responsible for crop loss amounting in the order billions of dollars annually. READ MORE

  7. 5. Averaged linear energy transfer and other beam quality descriptors inr elation to relative biological effectiveness

    Author : Fredrik Kalholm; Niels Bassler; Iuliana Toma-Dasu; Emanuele Scifoni; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LET; RBE; LQ-model; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : In radiotherapy with protons, a constant relative biological effectiveness (RBE) of 1.1 is traditionally applied, i.e. protons are assumed to be 10\% more effective than photons in killing cells. READ MORE
