Previous studies in patients with a history of Kawasaki disease (KD) have focused on the endothelial function of the coronary arteries and that of the systemic arteries is not fully understood. Furthermore, the effect of vitamin C on systemic vascular endothelial function after KD has not yet been elucidated. In the present study, 39 patients (age, 7.1 +/- 2.7 years) at 1-10 years after acute K...

Studies have reported a greater blood flow response to muscle contractions when the limb is below the heart compared with above the heart, and these results have been interpreted as evidence for a skeletal muscle pump contribution to exercise hyperemia. If limb position affects the blood flow response to other vascular challenges such as reactive hyperemia, this interpretation may not be correc...

Purpose: Many semi-automated and fully-automated approaches have been proposed in literature to improve the objectivity of estimation conjunctival hyperemia, based on image processing analysis eyes’ photographs. The purpose is its evaluation using faster systems independent by human subjectivity. Methods: In this work, we introduce a redness grading scales able completely automatize clinical pr...

A hemiparetic and aphasic patient, 3 days after acute traumatic transection of the left internal carotid artery requiring life-saving total embolic occlusion, revealed ipsilateral increased peripheral hemispheric 99mTc-HMPAO activity. Ten days postocclusion, HMPAO peripheral cortical flow normalized as hemiparesis and aphasia significantly cleared. The initial lateralized HMPAO hyperactivity pa...

A cranial window conforming to the contours of the underlying cerebral cortical surface was implanted successfully in 18 cats. Subsequently the left middle cerebral artery (MCA) was occluded inside the sealed cranium and changes in the superficial cortical vasculature were related to measurements of intracranial pressure (ICP), measured extradurally, and to the resulting infarcts. Vascular chan...
