Nitric oxide in cerebral vasodilation and headache.
research providing evidence that dura mater does not represent a mere covering to the central nervous system. The evidence provided by the authors is that CSD reduces blood flow in the dura mater and the hypothesis is that such reduction reflects metabolic changes in the brain via connections between cortical and dural blood supplies. The relevance of the finding is the possible activation of n...

15 صفحه اولCerebral blood flow asymmetries in headache-free migraineurs.
Regional cerebral blood flow (rCBF) asymmetries were studied in controls and patients with common and classic/complicated migraine using 133Xe inhalation with 8 homologously situated external collimators over each cerebral hemisphere. Migraine patients as a group more frequently had posterior rCBF asymmetries than controls (p less than 0.03). Although there were no differences in the number of ...
متن کاملShort Communications Cerebral Blood Flow Asymmetries in Headache-Free Migraineurs
Regional cerebral blood flow (rCBF) asymmetries were studied in controls and patients with common and classic/complicated migraine using Xe inhalation with 8 homologously situated external collimators over each cerebral hemisphere. Migraine patients as a group more frequently had posterior rCBF asymmetries than controls (p<0.03). Although there were no differences in the number of anterior rCBF...
متن کاملPulsatile flow in model cerebral aneurysms
We present an immersed boundary method based on volume penalization, with which pulsatile flow in a model cerebral aneurysm is simulated. The model aneurysm consists of a curved vessel merged with a spherical cavity. The dominant vortical structures arising in the time-dependent flow are discussed and the evolution of the maximal shear stress in the aneurysm is analyzed. We approximate flow pro...
