    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NSCLC; Lung Cancer; Epidemiology; Genetics; KRAS; Pathology; Biomarkers; Oncology; Onkologi;

    Abstract : The aim of this thesis was to explore the role of a spectrum of biomarkers, for disease classification or predictors of treatment outcomes in non-small cell lung cancer (NSCLC).Paper I examined the impact of systemic inflammation on the clinical outcome of NSCLC patients. READ MORE

  4. 2. ADHD and stress : Diurnal cortisol levels, early psychosocial adversity and perceived stress

    Author : Johan Isaksson; Frank Lindblad; Kent W Nilsson; Per Gustafsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; HPA-axis; cortisol; hypocortisolism; diurnal rhythm; trauma; adversity; medication; perceived stress; gender differences; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Abstract : The Hypothalamus-Pituitary-Adrenal axis (HPA-axis) with its end product cortisol mediates the physiological response to stress thereby promoting mobilization of energy. The cortisol levels follow a diurnal rhythm with a distinct awakening response. READ MORE

    Abstract : Reduced independent mobility of blind and low-vision individuals (BLVIs) cause considerable societal cost, burden on relatives, and reduced quality of life for the individuals, including increased anxiety, depression symptoms, need of assistance, risk of falls, and mortality. Despite the numerous electronic travel aids proposed since at least the 1940’s, along with ever-advancing technology, the mobility issues persist. READ MORE

  6. 4. Biomass Gasification-Based Biorefineries in Pulp and Paper Mills – Greenhouse Gas Emission Implications and Economic Performance

    Author : Johan Isaksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; heat integration; energy efficiency; CO2 emissions; process integration; pulp and paper mill; biomass gasification;

    Abstract : The pulp and paper industry has a great opportunity to take advantage of the experience about forestry and wood handling for production of renewable fuels, chemicals and materials. Residues from forestry, i.e., tops, branches and stubs, have great potential to become a raw material that can replace crude oil or natural gas in many applications. READ MORE

  7. 5. Studies on Nucleic Acids – Structure and Dynamics

    Author : Johan Isaksson; Jyoti Chattopadhyaya; Douglas H. Turner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; nucleic acids; modified nucleotides; NMR; structure; dangling-end; single-stranded; thermodynamics; hydration; Bioorganisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Abstract : This thesis is based on six papers, Papers I-VI, focusing on the interplay between the stabilizing elements of nucleic acids self-assembly; hydrogen bonding, stacking and solvent effects. In Paper I we investigate how the substitution of the O4' for CH2 in the sugar moiety of adenosine (2'-deoxyaristeromycin) at the A6 position of the Dickerson-Drew dodecamer makes the two modified bases exist in a dynamic equilibrium between Hoogsteen and Watson-Crick base pairing in the NMR time scale.
