  2. 6. Cardiovascular and respiratory effects of apnea in humans

    Author : Johan Andersson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

    Abstract : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. READ MORE

  4. 7. Blood Vessels, Biomarkers, and Broken Barriers: lnvestigations of the Brain Vasculature in Models of Neonatal Brain lnjuries

    Author : E. Axel Andersson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neonatal brain injury; hypoxia ischemia; germinal matrix haemorrhage; blood brain barrier; tight‐junctions; blood vessels;

    Abstract : Brain injury during the perinatal period can lead to lifelong impairment in cognitive and motor function, or an early death. Term neonatal encephalopathy and preterm germinal matrix haemorrhage are two conditions that can irreversibly injure the brain, but clinical tools for diagnosing and treating these pathologies are lacking.

  5. 8. NO Effect on Inflammatory Reaction in Extracorporeal Circulation : Ex vivo Studies

    Author : Mika Lahtinen; Jan Borowiec; Per Venge; Vibeke Videm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cardiac surgery; extracorporeal circulation; inflammatory reaction; NO; degranulation; neutrophil; eosinophil; basophil; complement; contact system; coagulation; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Clinical Chemistry; klinisk kemi;

    Abstract : Nitric oxide (NO) is expressed in inflammatory tissues. However, NO effects are controversial in inflammation; NO is described as acting in a dose dependent manner and possess both pro-inflammatory and anti-inflammatory properties. READ MORE

  6. 9. New Aspects of Mast Cell Progenitors in Health and Disease

    Author : Maya Salomonsson; Jenny Hallgren Martinsson; Silvia Bulfone-Paus; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mast cells; Mast cell progenitor; Lung function; Bone marrow; Blood; Activation; Chemotactic receptors;

    Abstract : Mast cells are tissue-resident immune cells that are well known for their involvement in asthma and allergy. They originate in the fetal yolk sac, or in the bone marrow. From the bone marrow, they are released as immature progenitors that are transported via the blood circulation to the peripheral tissue, where they mature. READ MORE

  7. 10. Effects of Ischaemia on the Neuroretina and Retinal Blood Vessels

    Author : Bodil Gesslein; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein kinase C; tumor necrosis factor; mitogen-activated protein kinases; pig; blood vessels; mfERG; Retinal ischaemia; vascular endothelial growth factor; hypoxia-inducible factor;

    Abstract : Identification of the intracellular signal transduction pathways activated in retinal ischaemia may be important in revealing novel pharmacological targets. The retinal blood vessels are key organs in circulatory failure, and in this work the retinal vasculature was therefore examined separately from the neuroretina. READ MORE
