Postnatal Maturation Modulates Cerebrovascular Myogenic Tone
<p>The present study focused on the main hypothesis that maturation decreases contractile reliance on calcium influx and myofilament Ca2+ sensitivity, and increases reliance on release of calcium from intracellular stores to develop and maintain pressure-evoked myogenic tone in rat cerebral blood …

Eph-mediated restriction of cerebrovascular arteriogenesis
… is the result of an occlusion in the arteriole cerebrovascular network. No effective treatment options exist to provide neuroprotection from occlusion, and limited success has been seen clinically when attempting to restore blood flow to vulnerable neural tissue regions. Enhancement of pial …

Cerebrovascular dysfunction : associations with midlife risk factors
… and structural changes in the brain and cerebrovascular circulation. The rationale for these projects is that continued investigation on the impact of individual and aggregate risk from various cardiovascular risk factors will help target early changes in structure and function that …

Cerebrovascular influence on brain and cognitive aging
A dysfunctional cerebrovascular system can result in severe adverse effects on brain health and cognitive aging. Recently, Fabiani et al., (2014) introduced a novel non-invasive approach of quantifying cerebrovascular health using diffuse optical imaging in a sample of older adults. This method is …

Endovascular Optical Coherence Tomography Imaging in Cerebrovascular Disease
… as an adjunct in the diagnosis and treatment of cerebrovascular diseases. Towards that goal, preclinical animal and human investigations were performed. We assessed the feasibility of OCT imaging in quantifying vascular injury after endovascular thrombectomy (EVT) in a swine model. OCT was found …

Peripheral and Cerebrovascular Function during the Female Lifespan
… via middle cerebral artery velocity (MCAv), cerebrovascular reactivity (CBV-R) and cerebral autoregulation. Peripheral vascular function (brachial and femoral artery endothelial function via flow mediated dilation (FMD)) and structure (brachial (b), femoral (f) and carotid (c) intima-media …

The effects of sitting on cerebrovascular and cognitive function
… (PA) levels. Despite associations between SB and cerebrovascular disease, little research has assessed the influence of SB on cerebrovascular function, comprising cerebral blood flow (CBF), cerebral autoregulation (CA) and cerebrovascular carbon dioxide reactivity (CVR). This is of upmost …

Cerebrovascular and Ventilatory Function in Chronic Obstructive Pulmonary Disease
… of studies set out to define the ventilatory and cerebrovascular responses to acute alterations in PCO2 and PO2 in COPD patients, and the relationship to oxidative stress. A secondary focus was to characterize both cerebral and peripheral blood flow during exercise. The thesis begins by …

Imitadores de ataque cerebrovascular en pacientes de la Fundacion Cardioinfantil
Introducción: El Ataque Cerebrovascular (ACV) es una emergencia médica que requiere atención inmediata para instaurar intervenciones que ayuden a mejorar su desenlace. Su diagnóstico es clínico, pero se confirma y clasifica con la ayuda de neuroimágenes. No obstante, hasta un 30% de los pacientes …

Importance of MAPK and PKC in cerebrovascular endothelin receptor changes
Endothelin is a vasoactive peptide that exerts its effect through two receptors; the endothelin type A (ETA) and type B (ETB) receptor. The contractile ETA receptor is localized on smooth muscle cells in the vascular wall, while the ETB receptors are mainly situated on endothelial cells, mediating …

ASSOCIATION BETWEEN ATRIAL SIZE AND CEREBROVASCULAR EVENTS: A RETROSPECTIVE, COHORT STUDY
… using the left atrial volume index (LAVi), and cerebrovascular events (CVE). Methods: We enrolled consecutive adults undergoing transthoracic echocardiography (TTE) between 2012 and 2023 at three teaching hospitals in Milan, Italy. Patients with a history of AF or receiving anticoagulant therapy …

The impact of ischaemic preconditioning on cerebrovascular function in healthy individuals.
… impact of RIPC on cerebral blood flow (CBF) or cerebrovascular function. The overall aim of this thesis was to assess, in healthy individuals, the impact of bilateral arm RIPC or SHAM on resting CBF, cerebrovascular reactivity, cerebral autoregulation, and autoregulation during hypercapnia. …

Multimodal Imaging of Inflammation at the Neurovascular Interface in Cerebrovascular Disease
A carotid atherosclerotic plaque represents a nidus of inflammation mere centimetres below the blood-brain barrier. This inflammation, along with associated regions of microcalcification, are histopathological features of atheroma at risk of rupture (so-called “vulnerable plaques”) that trigger …

Molecular Profiling and Mechanisms of Cerebrovascular Function in Health and Neurodegeneration
… RNAsequencing (snRNA-seq), we profile cerebrovascular nuclei across 11 subtypes, including endothelial cells, mural cells, and perivascular fibroblasts. We uncover human-specific expression patterns along the arteriovenous axis and determine previously uncharacterized cell type-specific …

The effectiveness of acupuncture in motor function recovery during cerebrovascular accident rehabilitation
Overview of the topic: Cerebrovascular accident occurs when a rapid development of clinical signs of focal or global disturbance happens in the cerebral function, which last more than 24 hours or has the potential to death, and must be caused by its vascular origin (Hatano, 1976). As a result, a …

Effects of Aerobic Exercise on Cognitive and Cerebrovascular Function in Hypertensive Adults
… contributions to cognitive activity. We measured cerebrovascular hemodynamics non-invasively during cognitive activity as a measure of neurovascular coupling. Adults with and without hypertension exhibit similar increases in large artery stiffness and decreases in extracranial hemodynamic …
