  2. 1. Defence on Demand : A physiological perspective on phenotypic plasticity in anti-predator traits

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phenotypic plasticity; inducible defences; stress physiology; cortisol; immune function; trade-offs; sexual dimorphism; crucian carp; visual ecology; predator-prey interactions; POMC pro-opiomelanocortin ; colour change; eco-immunology; Anti-predator defences; Inducible morphological defence; Phenotypic plasticity; Stress physiology; Cortisol; Immune function; Crucian carp; Predator-prey interactions; Trade-offs; Sexual dimorphism; POMC; Pro-opiomelanocortin; Visual ecology; Eye evolution; Melanin; Eco-immunology; Pace-of-life; Behavioural plasticity;

    Abstract : Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. READ MORE

  4. 2. Neuropeptide circuitries regulating food and water intake

    Author : Christian Broberger; Karolinska Institutet; Karolinska Institutet; []
    Keywords : agouti gene-related protein; anorexia mutation; arcuate nucleus; cholecystokinin; cocaine- and amphetamine-regulated transcript; coexistence; confocal microscopy; dorsal root ganglion; feeding; hypocretin; immunohistochemistry; in situ hybridization; melanin-concentrating hormone; nodose ganglion; nucleus tractus solitaxii; orexin; paraventricular nucleus; satiety; sensory neurones; pro-opiomelanocortin; vagus nerve;

    Abstract : An adequate supply of nutrients through food intake is critical for survival, as evidenced by disorders such as obesity and anorexia, which in the long run may be life-threatening. Feeding behaviour is ultimately controlled by interacting neuronal populations in the brain. READ MORE

  5. 3. Genetic and biological characterization of the anorexic anx/anx mouse

    Author : Jeanette Johansen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Pathological deviations in body weight is a major health problem. It is currently unclear how normal body weight and food intake is controlled. There is even less understanding of the mechanisms behind abnormal eating behavior as in anorexia and obesity. READ MORE

  6. 4. Alcohol and the effect on some appetite-regulating hormones in man

    Author : Jan Calissendorff; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Leptin; ghrelin; octanoylated; PYY3-36; GLP-1; obestatin; alcohol; NPY; IGF-1; IGFBP-1; insulin; glucose; testosterone; cortisol; catecholamines;

    Abstract : Beverage containing alcohol has been used for centuries to stimulate appetite. Ingestion of a moderate amount of alcohol increase energy intake. Regulation of food intake is complex. Several factors cooperate such as neural impulses from sensory organs; sight, smell, gut distension, social setting, memory, current energy status and hormones. READ MORE
