1. Blood Flow in Human Skeletal Muscle : The Effect of Adrenaline and the Influence of a Small Muscle Injury
Sammanfattning : A variety of vasoregulatory systems are involved in the complex control of blood flow inhuman skeletal muscle. The interaction between these systems where one system canoverride or modify the other makes blood flow regulation complicated. LÄS MER
2. Dynamic Fetal and Placental Circulatory Changes during Uterine Contractions
Sammanfattning : 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. LÄS MER
3. Cerebral blood flow and intracranial pulsatility studied with MRI : measurement, physiological and pathophysiological aspects
Sammanfattning : During each cardiac cycle pulsatile arterial blood inflates the vascular bed of the brain, forcing cerebrospinal fluid (CSF) and venous blood out of the cranium. Excessive arterial pulsatility may be part of a harmful mechanism causing cognitive decline among elderly. LÄS MER
4. Fetal Cardiac Function and Venous Circulation - Experiences with Velocity Vector Imaging
Sammanfattning : Placental dysfunction resulting in intrauterine growth restriction (IUGR) is a common complication of pregnany and severe IUGR, with ensuing fetal hypoxia is an important cause of perinatal mortality and morbidity. Doppler studies of fetal and maternal vessels are routinely used for fetal surveillance and alterations in fetal venous blood flow has been demonstrated as a late sign of fetal compromise. LÄS MER
5. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin
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.
