  2. 11. Turbulent Flow in Constricted Blood Vessels : Quantification of Wall Shear Stress Using Large Eddy Simulation

    Author : Roland Gårdhagen; Matts Karlsson; Toste Länne; Leif Rune Hellevik; Linköpings universitet; []
    Keywords : ;

    Abstract : The genesis of atherosclerosis has previously been shown to be affected by the frictional load from the blood on the vessel wall, called the wall shear stress (WSS). Assessment of WSS can therefore provide important information for diagnoses, intervention planning, and follow‐up. READ MORE

  4. 12. On macrophage contributions to tissue homeostasis : New insights on pancreas development and healing of ischemic injury

    Author : Carmen Herrera Hidalgo; Mia Phillipson; Andrés Hidalgo; Uppsala universitet; []
    Keywords : macrophages; islets of Langerhans; β cell function; postnatal β cell maturation; hindlimb ischemia; blood flow regulation; mural cells; vessel pruning; diabetes mellitus; ischemic diseases;

    Abstract : Besides providing host defence against innumerable threats, macrophages display additional key functions for preservation of tissue homeostasis. This thesis includes four studies that explore novel macrophage functions in both the development of islets of Langerhans and healing of ischemic injury in mice. READ MORE

  5. 13. Posture and brain function in dementia. A study with special reference to orthostatic hypotension

    Author : Ulla Passant; Sektion IV; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; falls and fractures.; white matter disease; hypoperfusion; frontal lobes; regional cerebral blood flow; blood pressure; orthostatic hypotension; Organic dementia; normal subjects; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik;

    Abstract : Orthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. READ MORE

  6. 14. Endothelial : mural cell interplay in regulation of blood- and lymph vessel development and function

    Author : Yixin Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Blood- and lymphatic vascular development and homeostasis depend on correct endothelial- mural cell interaction, and dysregulation thereof is apparent in multiple human diseases. However the mechanisms controlling the formation of these respective vascular systems are not fully understood. READ MORE

  7. 15. On the Autonomic Control of Blood Flow and Secretion in Salivary Glands. Functional and morphological aspects on muscarinic receptor subtypes in different species

    Author : Anders Ryberg; Göteborgs universitet; []
    Keywords : Muscarinic receptor subtype; neuronal; non-neuronal; expression; secretion; blood flow; salivary gland; human; rat; sheep;

    Abstract : Parasympathetic nervous activity is the principal stimulus for evoking fluid responses within salivary glands. Concomitantly to the onset of this response, the blood flow increases. READ MORE
