  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. Regional Lung Mechanics and Influence of an Active Diaphragm in Experimental Lung Injury

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mariangela Pellegrini; Uppsala universitet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute respiratory distress syndrome; artificial respiration; diaphragm; pulmonary atelectasis; lung imaging; respiratory system; animal model; Fysiologi; Physiology; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Despite being an essential life-support strategy in severe respiratory failure, mechanical ventilation can, if not optimally set and monitored, lead to injury of the lung parenchyma and diaphragm. These conditions are called ventilator-induced lung injury and ventilator-induced diaphragmatic dysfunction (VIDD), respectively. LÄS MER

  4. 4. 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

  5. 5. 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
