  3. 22. Vitamin D and blood pressure

    Författare :Ann Burgaz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The physiological function of circulating 25-hydroxyvitamin D (25(OH)D) is to maintain serum calcium range that supports skeletal system. Evidence is mounting that vitamin D has beneficial effects on other important functions in tissues not primarily related to mineral metabolism. LÄS MER

  4. 23. The human diving response : effects of temperature and training

    Författare :Erika Schagatay; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Djurfysiologi; pig; human; training; breath-holding time; breaking point; cold-receptors; arterial blood; vasoconstriction; bradycardia; diving reflex; diving response; Breath-hold diving; Animal physiology; simulated diving; Organism biology; Organismbiologi; Sports; Idrott; Physiology; Fysiologi;

    Sammanfattning : The aim was to elucidate the cardiovascular response associated with breath-hold diving, especially the effects of temperature in its elicitation and the effects of different types of training on the human diving response (DR) and breath-holding time (BHT), and to evaluate the human DR in a mammalian perspective. A model for simulated diving by apnea and facial immersion in cold water was developed. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 25. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions

    Författare :Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. LÄS MER
