  2. 1. Role of arginase in vascular function

    Author : Christian Jung; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Nitric oxide (NO) is central for the integrity of the cardiovascular system, the maintenance of endothelial function and the protection against ischaemic heart disease. The enzyme arginase is up-regulated during ischaemia-reperfusion and by hypoxia in cell culture and animal models which might be of pathophysiological relevance since it competes with NO synthase for their common substrate arginine.

  4. 2. Role of extracellular ATP in immune mechanisms against infections

    Author : Lalitha Tadala; Andrea Puhar; Sara I Wilson; Bernt Eric Uhlin; Mikael Sellin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extracellular ATP; invasive bacteria; Shigella; Listeria; plasma membrane ruffle; PIEZO1; infection; immune response; Hanta virus; molekylär cellbiologi; molecular cell biology;

    Abstract : Inflammation is driven either by infection with pathogens or sterile stimuli, such as tissue damage or autoimmune diseases. Upon tissue damage, ATP is released passively from the dead or compromised cells. During stress, ATP can be secreted from the cells. Extracellular ATP (eATP) acts as an endogenous danger signal.

  5. 3. Inflammation and subjective health : the role of sickness behaviour

    Author : Karin Lodin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sickness behaviour refers to a set of coordinated behavioural and psychological changes in response to inflammation aimed to redirect available energy to the immune system to promote recovery. Sickness behaviour symptoms closely resemble important determinants of poor self-rated health, which in turn has been coupled to increased levels of inflammatory cytokines. READ MORE

  6. 4. Essays on behavioral economics: Nudges, food consumption and procedural fairness

    Author : Verena Kurz; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Nudging; Field experiment; Meat consumption; Climate change mitigation; Decision heuristics; Food choice; Procedural fairness; Experiment; Coordination; Correlated equilibrium; Recommendations; Volunteer s dilemma;

    Abstract : Decreasing meat consumption holds significant potential for the reduction of human-induced greenhouse gas emissions and the mitigation of climate change. Fostering behavioral change to reduce climate emissions related to food consumption is challenging and requires new strategies based on an understanding of human decision-making. READ MORE

  7. 5. Low dose ketamine : analgesia and side-effects in patients and volunteers

    Author : Jan Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : There is a need for novel approaches in the pharmacological treatment of pain. In many pain states the present treatment options are insufficient. Altered processing in sensory pathways often underlies such intractable pain. READ MORE
