  2. 1. Carbon monoxide in biological systems : An experimental and clinical study

    Author : Anna-Maja Åberg; Jan-Erik Larsson; Dick Delbro; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbon monoxide; physiological effects; systemic inflammation; analytical method; blood; exhaled air; pharmacokinetics; cigarette smoking; blood donation; cytokines; Anaesthetics; Anestesiologi;

    Abstract : Background: Carbon monoxide (CO) is a toxic gas, but it is also produced endogenously when haem is degraded. When produced in vivo, CO is believed to have positive biological effects. For example it activates the production of cyclic guanosine mono-phosphate and causes vasodilatation. READ MORE

  4. 2. Gas Embolism in Laparoscopic Liver Surgery

    Author : Diddi Fors; Sten Rubertsson; Dag Arvidsson; Tor Inge Tønnessen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas embolism; laparoscopic liver; CVP; PEEP; high frequency jet ventilation; cardiopulmonary physiology; carbon dioxide; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård;

    Abstract : Laparoscopic liver surgery is complicated due to the structure of this organ with open sinusoids. A serious disadvantage is the risk of gas embolism (GE) due to CO2 pneumoperitoneum. CO2 can enter the vascular system through a wounded vein. A common opinion is that gas fluxes along a pressure gradient, e. READ MORE

  5. 3. Proteomic, metabolomic, and microbiome studies of blood pressure

    Author : Yi-Ting Lin; Johan Sundström; Martin Magnusson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; hypertension; proteomics; metabolomics; microbiome; molecular epidemiology; Mendelian randomization;

    Abstract : Hypertension is a major risk factor for cardiovascular disease and premature death with a substantial global economic burden. To prevent and treat hypertension, it is crucial to improve our understanding of the pathophysiological mechanisms. Hypertension is a multifactorial condition influenced both by genetic and environmental factors. READ MORE

  6. 4. Gas discrimination for mobile robots

    Author : Marco Trincavelli; Amy Loutfi; Silvia Coradeschi; Alcherio Martinoli; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : The problem addressed in this thesis is discrimination of gases with an array of partially selective gas sensors. Metal oxide gas sensors are the most common gas sensing technology since they have, compared to other gas sensing technologies, a high sensitivity to the target compounds, a fast response time,they show a good stability of the response over time and they are commercially available.

  7. 5. Pitfalls in Interpreting Umbilical Cord Blood Gases and Lactate at Birth

    Author : Parisa Mokarami; Urogynekologi och reproduktionsfarmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood gases; metabolic acidosis; umbilical cord; round-off; delayed sampling; validation;

    Abstract : Acid-base status in umbilical cord blood is an objective measure of the fetus’ exposure to and ability to handle hypoxia. The objective of this thesis was to clarify some of the methodological pitfalls in interpreting umbilical cord blood gases and lactate values at birth. READ MORE
