NEUROVASCULAR COUPLING DURING AGEING AND INMIGRANEURS

open access: yesZdravniški Vestnik, 2008
A noninvasive assessment of neurovascular coupling using visually evoked cerebral bloodflow velocity responses (VEFR) and visual evoked potentials (VEP), during normal ageingand in migraneurs, would be of great importance for interpretation of functional

Elevation of Stearoyl‐Coenzyme A Desaturase and Monounsaturated Fatty Acids in Parkinson's Disease Serum

open access: yesMovement Disorders, EarlyView.
Abstract Background Emerging evidence indicates that dysregulation of monounsaturated fatty acids (MUFAs), synthesized by the enzyme stearoyl‐coenzyme A desaturase (SCD), impacts on α‐synuclein pathology in the Parkinson's disease (PD) brain. Objective The objective of this study was to analyze SCD and MUFA‐enriched lipids in the periphery of patients ...

Analysis of neurovascular coupling in migraneours

open access: yesZdravniški Vestnik, 2005
Background: According to recent data it is not clear whether neurovascular coupling is disturbed in migraneours during headache free period. The aim of our study was to establish whether the relationship between visually evoked cerebral blood flow ...

An interaction graph approach to gain new insights into mechanisms that modulate cerebrovascular tone

open access: yesCommunications Biology
Mechanisms to modulate cerebrovascular tone are numerous, interconnected, and spatially dependent, increasing the complexity of experimental study design, interpretation of action-effect pathways, and mechanistic modelling. This difficulty is exacerbated

Natural Killer Subset Changes and Vascular Endothelial Growth Factor‐A Plasma Profile in Progressive Supranuclear Palsy: The NKscape Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Emerging evidence implicates neuroinflammation in progressive supranuclear palsy (PSP) pathophysiology, with elevated cyto‐chemokines suggesting natural killer (NK) cell involvement. Methods We characterized peripheral NK in PSP (N = 11) versus Parkinson's disease (PD, N = 10) and healthy controls (HC, N = 8) at both ...

Macroscale Gradient‐Informed Neural Oscillation Topography in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by large‐scale disruptions in beta and gamma oscillations. Although subcortical beta power is an established biomarker for current adaptive deep brain stimulation (aDBS), it may not fully capture the global pathophysiological burden and the macroscale hierarchical reorganization of the ...

FMRI Approaches to Mapping Cerebrovascular Reactivity: Comparison of Gradient Echo BOLD and Spin Echo BOLD With Arterial Spin Labeling

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To compare markers of cerebrovascular reactivity (CVR) measured with Gradient Echo (GE, T2*w) and Spin‐Echo (SE, T2w) BOLD fMRI with quantitative physiological CVR measured using ASL. Methods CVR, the ability of blood vessels to dilate and increase cerebral blood flow (CBF), can be investigated with ASL fMRI but has a low signal‐to ...

Double Asymmetric Spin Echo EPI (dASE‐EPI) Enables fMRI of the Entire Rat Brain at 9.4 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Development and evaluation of a double asymmetric spin echo planar imaging (dASE‐EPI) sequence to balance sensitivity to blood oxygenation level‐dependent (BOLD) contrast with mitigation of susceptibility‐induced intravoxel spin dephasing in ultra high‐field rodent brain imaging.

Research status and trends of Piezo1 and brain: A bibliometric analysis

open access: yesNeuroprotection, EarlyView.
This graphical abstract illustrates the workflow and key findings of the bibliometric analysis of Piezo1 in brain research. The primary results were visually centered on a brain graphic highlighting the Piezo1 channel, and three converging research hotspots were identified: neurovascular regulation, calcium signaling, and neuroinflammation.

Activatable smart contrast agents for photoacoustic imaging

open access: yesSmart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...
