  1. 1. Artificial Neural Networks (ANN) in the Assessment of Respiratory Mechanics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Gaetano Perchiazzi; Uppsala universitet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; artificial neural networks; respiratory system compliance; respiratory system resistance; respiratory system time constant; intrinsic positive end expiratory pressure; PEEPi; animal model; acute lung injury; oleic acid; Otis model; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi;

    Sammanfattning : The aim of this thesis was to test the capability of Artificial Neural Networks (ANN) to estimate respiratory mechanics during mechanical ventilation (MV). ANNs are universal function approximators and can extract information from complex signals. LÄS MER

  2. 2. Studies on stress in African green monkeys (Cercopithecus aethiops) : Stress associated cortisol and prolactin levels, lymphocyte modulation and pathological changes in adrenal cortex, stomach and hippocampus in the African green monkey (C. aethiops)

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mbaruk Abdalla Suleman; Uppsala universitet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; adrenal cortex; capture; confinement; cortisol; husbandry; housing; hippocampus; lymphocytes; prolactin; stomach; stress; wild; African green monkeys; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : African green monkeys (AGMs) are highly susceptible to captivity-induced stress. An investigation of spontaneous deaths of laboratory confined AGMs at the Institute of Primate Research, Nairobi, Kenya over a period of 7.5 years documented mild to severe gastric mucosal erosions and ulcers in 83 of 260 (32%) necropsies.

  3. 3. Diabetes-induced Alterations in Renal Microcirculation and Metabolism

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Fredrik Palm; Uppsala universitet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; diabetes mellitus; kidney; nephropathy; oxygen tension; haemodynamic; nitric oxide; oxygen consumption; radical oxygen species; polyol pathway; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi;

    Sammanfattning : Diabetes-induced renal complications, i.e. diabetes nephropathy, are a major cause of morbidity and mortality. The exact mechanism mediating the negative influence of hyperglycaemia on renal function is unclear, although several hypotheses have been postulated. LÄS MER

  4. 4. Microcirculation, Mucus and Microbiota in Inflammatory Bowel Disease

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Olof Schreiber; Uppsala universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammatory bowel diseases; experimental colitis; DSS; TNBS; colonic mucosal blood flow; laser-doppler flowmetry; colonic mucus thickness; MUC2; colonic mucosal barrier function; iNOS; eNOS; probiotics; Lactobacilli; Lactobacillus reuteri; colonic microbiota; T-RFLP; bacterial translocation; intravital microscopy; P-selectin; leukocyte recruitment; platelet recruitment; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; Physiology; Fysiologi;

    Sammanfattning : Inflammatory bowel diseases, (IBD), are a group of chronic disorders of the gastro-intestinal tract, and include Crohn’s disease (CD) and Ulcerative Colitis (UC). The pathogenesis is not known, but involves at least in part a loss of tolerance towards the commensal colonic microbiota. LÄS MER

  5. 5. Mitochondrial form and function in pancreatic β-cells and brown adipocytes

    Detta är en avhandling från The Wenner-Gren Institute,Stockholm University

    Författare :Jakob D Wikström; Stockholms universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondria; beta cells; brown adipose tissue; diabetes; obesity; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; fysiologi; Physiology;

    Sammanfattning : This thesis is focused on the role of mitochondria in pancreatic β-cells and brown adipose tissue (BAT). Two main aspects of mitochondria were explored; mitochondrial functional efficiency and the interrelationship between mitochondrial shape and function. LÄS MER
