  1. 1. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin

    Författare :Lena Lindholm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiopulmonary bypass; cardiac surgery; regional oxygenation; venous oxygenation; splanchnic oxygenation; insulin; vasodilation; temperature; pump flow;

    Sammanfattning : Surgical trauma triggers neural, endocrine and inflammatory reactions with subsequent alterations in systemic and regional blood flow, blood pressure and metabolism. These changes are detectable after all major surgical procedures but are often more pronounced after cardiac surgery, probably because of blood exposure to artificial surfaces of the heart lung machine, temperature modulation (e.

  2. 2. The Microvasculature of Endogenous and Transplanted Pancreatic Islets : Blood Perfusion, Oxygenation and Islet Endocrine Function

    Författare :Richard Olsson; Per-Ola Carlsson; Leif Jansson; Arne Andersson; Thomas Linn; Uppsala universitet; []
    Nyckelord :Cell biology; diabetes mellitus; pancreatic islets; islet transplantation; vascular engraftment; islet microcirculation; oxygenation; blood flow; protein biosynthesis; Cellbiologi;

    Sammanfattning : Type 1 diabetes mellitus affects millions of people worldwide. Islet transplantation is a minimal invasive surgical procedure that restores euglycemia and halts the progression of diabetic complications. However, despite transplantation of islets from multiple donors most patients reverse to hyperglycemia within five years. LÄS MER

  3. 3. Biotransformations of Turpentine Constituents : Oxygenation and Esterification

    Författare :Marica Lindmark-Henriksson; KTH; []
    Nyckelord :Picea abies; Pinaceae; Essential oils composition; Terpene alcohol; Hemiacetal; Hemiacetal ester; TMP-turpentine; Monoterpene; alpha-pinene; beta-pinene; Limonene; Verbenol; Pinocarveol; Borneol; Myrtenol; Suspension cell culture; Biotransformation; ;

    Sammanfattning : This thesis describes methods to obtain value–addedcompounds from TMP-turpentine obtained from the spruce, Piceaabies. The methodology focuses on biotransformations using twoapproaches: an oxygenation approach (i.e. oxygenation ofterpene hydrocarbons by cell cultures) and an esterificationapproach (i. LÄS MER

  4. 4. Synchronized delivery of inspired nitric oxide : Effects on oxygenation and pulmonary tension during artificial ventilation

    Författare :Erkki Heinonen; Tim Higenbottam; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; nitric oxide; pulsed administration; pulmonary hypertension; oxygenation; equine; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Sammanfattning : Nitric oxide (NO) is a mediator of vascular smooth muscle tension that metabolises rapidly in blood. NO delivered by inhalation can therefore be used as a selective pulmonary vasodilator to relieve pulmonary hypertension or to improve oxygenation with no systemic effects. LÄS MER

  5. 5. Brain Tissue Oxygenation in Traumatic Brain Injury : Experimental and Clinical Studies

    Författare :Karlis Purins; Anders Lewén; Per Enblad; Oliver Sakowitz; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain tissue oxygenation; Cerebral metabolism; Traumatic brain injury; Cerebral ischemia; Threshold levels; Neurovent-PTO; Microdialysis; Neurosurgery; Neurokirurgi;

    Sammanfattning : Traumatic brain injury (TBI) is a major cause of death and disability. TBI is frequently followed by cerebral ischemia which is a great contributor to secondary brain damage. The main causes of cerebral ischemia are pathophysiological changes in cerebral blood flow and metabolism. LÄS MER
