1. 21. Anaesthetics and the blood vessel wall. Actions of propofol and sevoflurane on sympathetic and endothelial control of smooth muscle function

   Författare :Karin Thorlacius; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; intensive care; Anestesiologi; intensivvård; vein.; artery; endothelium; sympathetic nervous system; inhalation agent sevoflurane; Anaesthesia; intravenous propofol;

   Sammanfattning : The anaesthetics we use today dose-dependently decrease the mean arterial pressure partly due to direct or indirect effects on the blood vessels. In the present thesis human omental arteries and veins and rat femoral arteries were investigated in vitro concerning the effects of the intravenous anaesthetic propofol and the volatile anaesthetic sevoflurane on the function of the perivascular sympathetic nerves and the endothelial cells.

3. 22. Angiotensin II Receptors in the Human Coronary Circulation and in Heart Failure

   Författare :Emil Pantev; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Heart Failure; Human Coronary Arteries; Angiotensin II; AT receptors;

   Sammanfattning : Angiotensin II (Ang II) is a potent vasoconstrictor that is implicated in the pathogenesis of hypertension, heart failure and atherosclerosis. In this thesis, the efficacy and safety of Ang II receptor blockers (ARB) were evaluated. LÄS MER

4. 23. Altered vascular responses in experimental congestive heart failure

   Författare :Anders Bergdahl; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Kardiovaskulära systemet;

   Sammanfattning : Congestive heart failure is accompanied with increased circulatory levels of several vasoregulatory neurotransmitters and hormones which affect the outcome of this disease. In this thesis the blood levels of several vasoactive peptides in humans with congestive heart failure and their effects on the vasculature by the use of an animal model of heart failure were studied.

5. 24. Towards Emotion inspired Computational Intelligence (EiCI)

   Författare :Mahboobeh Parsapoor; Bertil Svensson; Urban Bilstrup; Jorge Armony; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : One of the main challenges in the computational intelligence (CI) community is to develop nature-inspired algorithms that can efficiently solve real-world problems such as the prediction of space weather phenomena. An early example in this context is taking inspiration from the biological neurons in the mammal’s nervous system and developing an artificial neuron. LÄS MER

7. 25. A Glial Role in the Action of Electroconvulsive Therapy

   Författare :Malin Wennström; Enheten för psykiatrisk neuromodulering (PNU); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psykiatri; klinisk psykologi; psykosomatik; psychosomatics; clinical psychology; Psychiatry; Hippocampus; Depression; Gliogenesis; Electroconvulsive seizures;

   Sammanfattning : The aim of the current thesis was to investigate glial responses to electroconvulsive seizures (ECS), an animal model of the fast-acting antidepressant treatment electroconvulsive therapy (ECT). Depression, a common and devastating disorder, has in recent years been associated with volumetric changes in prefrontal cortex, hippocampus and amygdala, brain regions known to be implicated in emotional behavior.
