  2. 11. Circulating Biomarkers in Patients with Head and Neck Cancer and the Influence of Cigarette Smoking

    Author : Bengt-Åke Andersson; Nongnit Laytragoon-Lewin; Pierre Åman; Charlotta Dabrosin; Mikael Johansson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Head and neck cancer (HNC) is a collective name for heterogeneous tumors located in the head and neck regions for which smoking, alcohol and human papillomavirus (HPV) are documented risk factors. The survival of HNC patients has only improved marginally during the last decade. READ MORE

  4. 12. Screening for Candidate Brain Tumor Genes : Identifying Genes that Cooperate with Platelet-Derived Growth Factor in Glioma Development and Progression

    Author : Fredrik Johansson; Bengt Westermark; Leif Carlsson; Uppsala universitet; []
    Keywords : Pathology; PDGF; insertional mutagenesis; retroviral tagging; common insertion site; glioma; expression; cGMP-dependent protein kinase II; Patologi;

    Abstract : Malignant primary brain tumors, gliomas, often overexpress both platelet-derived growth factor (PDGF) ligands and receptors providing an autocrine and/or paracrine boost to tumor growth. Glioblastoma multiforme (GBM) is the most frequent glioma. Its aggressive and infiltrative growth renders it extremely difficult to treat. READ MORE

  5. 13. Theoretical understanding of the coping approaches and social support experiences of relatives of critically ill patients during the intensive care unit stay and the recovery period at home

    Author : Ingrid Johansson; Fridlund Bengt; Cathrine Hildingh; Bodil Wilde; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coping; critical care; family; models; qualitative methods; social support; Caring sciences; Vårdvetenskap;

    Abstract : Relatives may experience a difficult and demanding situation when the patient is critically ill. During the period in the intensive care unit (ICU), the relatives may be subject to strong emotions of an existential nature, and the situation may involve several stressors as a result of changed roles, responsibilities and routines.

  6. 14. Characterization of catalytic reactions on surfaces from three-dimensional partial pressure distributions

    Author : Martin Johansson; Bengt Andersson; Linköpings universitet; []
    Keywords : ;

    Abstract : A chemical reaction taking place on a surface exposed to a viscous gas will give rise to a nonhomogeneous gas composition and temperature in the vicinity of the surface. This is due to the limited rate at which species and heat can be transported in the gas mixture by convection and diffusion. READ MORE

  7. 15. Methods for interval-censored data and testing for stochastic dominance

    Author : Angel G. Angelov; Magnus Ekström; Maria Karlsson; Bengt Kriström; Per Johansson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interval-censored data; Informative censoring; Self-selected intervals; Questionnaire-based studies; Maximum likelihood; Permutation test; Two-sample test; Stochastic dominance; Four-decision test; Statistics; statistik;

    Abstract : This thesis includes four papers: the first three of them are concerned with methods for interval-censored data, while the forth paper is devoted to testing for stochastic dominance.In many studies, the variable of interest is observed to lie within an interval instead of being observed exactly, i.e. READ MORE
