Measurement of Cerebral Metabolism and Vascular Function with Magnetic Resonance Imaging
… employs phase-contrast MRI for quantitative blood flow measurement and T2-relaxation-under-spin-tagging (TRUST) MRI for venous oxygenation estimation. During this thesis, I conducted several technical development studies. I first optimized TRUST and phase-contrast MR imaging parameters and …

The Integrative relationship between insulin and insulin-like growth factor 1 induced cardiovascular responses and sympathetic nervous responses
… to decrease cardiovascular tone and increase blood flows in skeletal muscle. Insulin has also been showed to increase sympathetic nerve activity that may play a role in the regulation of cardiovascular dynamics. This study investigated the effects of insulin and IGF-l on cardiovascular …

Ultrasound-based Noninvasive Monitoring Methods for Neurocritical Care
… relies on a steady uninterrupted supply of blood for its metabolic needs. Short-lived disruptions in cerebral blood supply can cause permanent damage. Likewise, mechanical stress on the brain can cause life-threatening and long-lasting damage to neural tissue. Existing neuromonitoring …

Use of fluorescent micropsheres to measure coronary flow reserve in rat animal model
Heart attacks result from reduced or blocked blood flow through major coronary arteries, resulting in permanent damage to heart muscle. Coronary blood flow (CBF) is thus important to measure in experimental animal models of heart disease. A standard method to measure CBF uses tracer microspheres (O …

Lignocaine extraction ratio and clearance as an indicator of hypoxic hepatic injury : a study using the in situ and the isolated perfused pig liver
… any detrimental effects on liver function and blood flow in vivo, hepatic lignocaine elimination and the effects of lignocaine administration on hepatic function and blood flow were studied in the anaesthetized pig, surgically prepared to allow sampling across the liver and direct hepatic blood …

Pseudo Random Arterial Modulation (PRAM): A Novel ASL Approach to Measure Flow and Blood Transit Times
… is a non-invasive MRI based method to measure blood flow. It does not require any contrast agent but rather uses water protons in the body as the contrast. PRAM is based on a pseudo random sequence of inversions and non-inversions of the arterial blood using radio frequency (RF) pulses at a …

Peripheral blood flow changes in response to post-exercise cold water immersion
… core body, muscle and skin. Given the role of blood flow in convective heat flux, substrate delivery and metabolic waste clearance, it is important to understand the influence of different water temperatures on compartmental distribution of limb blood flow during CWI. Therefore, the purpose of …

MAPK and pro-inflammatory mediators in the walls of brain blood vessels following cerebral ischemia
… stroke. Both are associated with disruption of blood flow to a part of the brain with rapid depletion of cellular energy and oxygen, resulting in ionic disturbances and eventually neuronal cell death [3]. The pathologic process that develops after stroke is divided into acute (within hours), …
