  1. 1. Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"

    Detta är en avhandling från Department of Health Sciences, Lund University

    Författare :Faina Reinprecht; Lund University.; Lunds universitet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; samhällsmedicin; Social medicine; Socialmedicin; Gerontologi; Gerontology; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; regional cerebral blood flow; cohort study; Neurology; neuropsychology; blood pressure; blood pressure monitoring; risk factors; Hypertension;

    Sammanfattning : "Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. LÄS MER

  2. 2. Cerebral blood flow and intracranial pulsatility studied with MRI measurement, physiological and pathophysiological aspects

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Anders Wåhlin; Umeå universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arterial Pulsatility; cerebrospinal fluid; cerebral blood flow; venous flow; intracranial pressure; pulse pressure; dementia; hippocampus; multiple sclerosis; magnetic resonance imaging; radiofysik; radiofysik;

    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

  3. 3. Endothelium-derived substances and regional hemodynamics in experimental hypertension

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sven-Olof Granstam; Uppsala universitet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; nitric oxide; endothelin; hypertension; rats; SHR; hemodynamics; blood pressure; blood flow; acetylcholine; carvedilol; microsphere method; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The spontaneously hypertensive rat (SHR), a model for experimental hypertension, is considered to have similarities with essential hypertension in humans. Differences between SHR and normotensive Wistar Kyoto rats (WKY) in the vascular response to endothelial-derived substances such as nitric oxide (NO) have been intensively studied in vitro. LÄS MER

  4. 4. Cerebral Blood Flow and Cognition. Clinical studies on Dementia and Cognitive Decline

    Detta är en avhandling från Dr Arkadiusz Siennicki-Lantz, Dept of Community Medicine, Malmö University Hospital, S-205 02 Malmö, Sweden

    Författare :Arkadiusz Siennicki-Lantz; Lund University.; Lunds universitet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gerontology; Gerontologi; vascular risk factors; carotid ultrasound; peripheral arterial disease; orthostatic hypotension; blood pressure; ageing; SPECT; cerebral blood flow; cognition; Dementia; Alzheimer’s disease;

    Sammanfattning : The importance of early detection of brain changes during ageing has been recognised. Single photon emission computed tomography (SPECT) is a method used for estimation of cerebral blood flow (CBF) in clinical work and in research. LÄS MER

  5. 5. Endogenous Nitric Oxide Production and Pulmonary Blood Flow during different experimental lung conditions

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Manja Nilsson; Uppsala universitet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; MEDICINE Surgery Anaesthetics and intensive care; MEDICIN Kirurgi Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. LÄS MER
