2. 16. Pressure autoregulation of cerebral blood flow in traumatic brain injury and aneurysmal subarachnoid hemorrhage

   Author : Ulf Johnson; Per Enblad; Lars-Owe Koskinen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral blood flow; autoregulation; traumatic brain injury; subarachnoid hemorrhage; Neurosurgery; Neurokirurgi;

   Abstract : The ability of the brain to keep a stable and adequate cerebral blood flow (CBF) independently of fluctuations in systemic blood pressure is referred to as cerebral pressure autoregulation (CPA). When the brain is injured by trauma or hemorrhage, this ability may be impaired, leaving the brain vulnerable to events of high or low blood pressure. READ MORE

4. 17. Augmentation of vital organ blood flow during experimental cardiopulmonary resuscitation

   Author : Rolf Gedeborg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac arrest; cardiopulmonary resuscitation; epinephrine; high-dose epinephrine; buffer; cerebral blood flow; post-resuscitation period; aortic occlusion; Kirurgi; Surgery; Kirurgi; Anestesiologi; Anaesthesiology;

   Abstract : Clinical outcome from cardiac arrest remains poor. If the time from arrest to restoration of spontaneous circulation can be shortened and resuscitation techniques improved so that higher blood flow and oxygen delivery to vital organs is achieved, it is possible that the outcome from cardiac arrest could improve.

5. 18. Dynamic Fetal and Placental Circulatory Changes during Uterine Contractions

   Author : Hui Li; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexualitet; reproduktion; andrologi; gynekologi; Obstetrik; sexuality; reproduction; andrology; gynaecology; Obstetrics; Venous; Uterine; Umbilical; Resistance; Pregnancy; Oxytocin; Labor; IUGR; Flow; Doppler; Contraction; Brain-sparing; Cerebral;

   Abstract : The best mode of delivery for fetuses with intrauterine growth restriction (IUGR) and umbilical artery (UA) blood flow changes is not well elucidated. Uterine artery, fetal UA, middle cerebral artery (MCA), and venous blood flow changes during uterine contractions during an oxytocin challenge test (OCT) have not been observed systemically.

6. 19. Inflammation and immunothrombosis in cerebral cavernous malformation : Novel molecular targets for the treatment of an incurable disease

   Author : Maria Ascención Globisch; Peetra Magnusson; Elisabetta Dejana; Marie Jeansson; Anna Randi; Uppsala universitet; []
   Keywords : Cavernoma; Inflammation; Coagulation; Blood-brain-barrier; Blood; Hypoxia; Propranolol; Biologi med inriktning mot molekylär immunologi; Biology with specialization in Molecular Immunology;

   Abstract : Cerebral cavernous malformation (CCM) is a vascular disease that causes mulberry-like lesions (cavernomas) in the central nervous system (CNS). Cavernomas are fragile, leaky and prone to rupture which may cause symptoms such as epileptic seizures, focal neurological deficits and hemorrhagic strokes. CCM lesions can appear sporadically in 0.

7. 20. Cerebral Hemodynamics through Intracrnial Pressure

   Author : Sima Shahsavari; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intracranial dynamics; Baroreceptor reflex; Secondary brain injury; Traumatic brain injury; Collapsible tubes; Intracranial pressure; Cushing reflex; Pulse wave propagation; Cerebral autoregulation; Cerebral compliance; Mathematical modelling;

   Abstract : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainly focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. READ MORE
