1. Carotid Artery Wall Layer Dimensions during and after Pre-eclampsia : An investigation using non-invasive high-frequency ultrasound
Sammanfattning : Pre-eclampsia is associated with increased risk of cardiovascular disease (CVD) later in life. The ‘gold standard’ for estimating cardiovascular risk - ultrasound assessment of the common carotid artery intima-media thickness (CCA-IMT) - does not convincingly demonstrate this increased risk.

2. Ultrasound-enhanced Fibrinolysis Pro-fibrinolytic and Non-beneficial Effects Of Ultrasound Exposure
Sammanfattning : The aim of this study was to further clarify the pro-fibrinolytic effects, and to explore the possible non-beneficial effects in ischemic organs, during exposure to pulsed ultrasound. This was accomplished by studies of the effects of different intensities of pulsed ultrasound exposure on the fibrinolytic properties of streptokinase and reteplase. LÄS MER
3. Epiphora : impact on vision, outcome of lacrimal surgery and investigations with ultra-high-frequency ultrasound
Sammanfattning : Epiphora is a common condition that often receives little attention. Excessive tear production creates an irregular and ever-changing ocular surface, affecting refraction and reducing vision. However, in a standard test situation the visual acuity is seldom affected, leading to the misinterpretation that epiphora is a minor problem. LÄS MER
4. Cerebral intraventricular hemorrhage and post-hemorrhagic ventricular dilatation in preterm infants: new mechanistic insights and potential treatment strategies
Sammanfattning : Intraventricular hemorrhage (IVH) is one of the major co-morbidities of premature birth associated with post-hemorrhagic ventricular dilatation (PHVD) development, long-term neurodevelopmental impairment, behavioral problems, special educational needs, and dependency on social security.Hypothesis and aims: We believe that extravasated blood and further release of extracellular hemoglobin (Hb) are crucial in brain injury following IVH and consequent development of PHVD.

5. Ultrasound evaluation of atherosclerosis and other cardiovascular sources of cerebral embolism
Sammanfattning : The search for embolic sources has high priority in patients presenting with suspected cerebral embolism. Non-invasive cardiovascular ultrasound is frequently used to reveal the presence of carotid stenosis and cardiac disorders with embolic potential. LÄS MER
