2. 11. Cardiac surgery and the brain - studies on cerebral blood flow autoregulation and mechanisms of cerebral injury

   Author : Björn Reinsfelt; Göteborgs universitet; []
   Keywords : Cardiac surgery; cerrebral dysfunction; cardiopulmonary bypass; anaesthetics; aortic valve replacement; transcranial Doppler; cerebraospinal fluid; blood-brain barrier;

   Abstract : Cardiac surgery and the brain - studies on cerebral blood flow autoregulation and mechanisms of cerebral injury Björn Reinsfelt Department of Anaesthesiology and Intensive Care, Institute of Clinical Sciences, The Sahlgrenska Academy, University of Gothenburg, Sweden Abstract Cerebral dysfunction (CD) occurs frequently after cardiac surgery with cardiopulmonary bypass (CPB). The main causes of CD are thought to be cerebral hypoperfusion, cerebral microembolisation , cerebral inflammation or disruption of the blood brain barrier (BBB). READ MORE

4. 12. Role of cerebral Blood Flow in Fetal Surveillance

   Author : Riffat Cheema; Urogynekologi och reproduktionsfarmakologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : ABSTRACT In high-risk pregnancies the chronic hypoxemic fetus redistributes its circulation to maintain the blood supply to the vital organs: brain, heart and adrenals. The aims of the studies included in this thesis were: 1) to establish reference curves for fetal cerebral venous blood velocity in normal pregnancies; 2) to determine in high-risk pregnancies the frequency of abnormal Doppler in the cerebral veins and uterine, umbilical and middle cerebral arteries and the umbilical vein and ductus venosus with correlation with adverse perinatal outcome; 3) to analyze the correlation between brain sparing and redistribution of circulation and placental vascular impedance; 4) to evaluate the correlation between brain sparing and fetal umbilical cord blood gases at birth.

5. 13. Regulation and measurement of brown adipose tissue blood flow

   Author : Gustavo Abreu-Vieira; Jan Nedergaard; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysiologi; Physiology;

   Abstract : Brown adipose tissue (BAT) is an organ specialized in macromolecule combustion in order to produce heat. Because of its high capacity to dissipate energy, it is currently among the best hopes for future treatments of obesity and diabetes. READ MORE

6. 14. Human Fetal Hemoglobin : Biochemical Characterization and Recombinant Production

   Author : Khuanpiroon Ratanasopa; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blood substitutes; HBOCs; HbF; recombinant hemoglobin; pseudoperoxidase; ITC; haptoglobin;

   Abstract : Blood transfusion is a common medical procedure when oxygen supply in the body is impaired. However, blood transfusion is not always without risks. The uncontrolled spreading of blood borne pathogens such as HIV or hepatitis B and C virus has urged researchers to look for “blood substitutes”. READ MORE

7. 15. Preservation of parathyroid function in thyroid and parathyroid surgery

   Author : Stefan Ander; Göran Åkerström; Linköpings universitet; []
   Keywords : Human parathyroid glands; vascular supply; parathyroid preservation; laser Doppler flowmetry; iPTH; autotransplantation; xenotransplantation; a thymic mice; angiogenesis; immunohistochemistry; electron microscopy; ultrastructure; autoradiography; MEDICINE; MEDICIN;

   Abstract : Preservation of normal parathyroid function and calcium homeostasis after operations on the thyroid and parathyroid glands is a difficult assignment in endocrine surgery, and it is crucial to minimise the risks of permanent postoperative hypoparathyroidism. The aim of this thesis was to study the vascular supply of the parathyroid glands and the revascularisation, growth, and function of transplanted parathyroid tissue, in order to add new information about parathyroid preservation.
