Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...

Abstract Background Dexmedetomidine infusions are beneficial in anaesthetised endotoxaemic horses when administered concurrent to endotoxin, but post‐conditioning effects are unknown. Objectives To evaluate whether a dexmedetomidine infusion is beneficial in horses administered Escherichia coli O55:B5 lipopolysaccharides (LPS) endotoxin prior to ...

Arterial Perivascular Space‐Mediated Solute Transport in the Mouse Brain
The mechanisms underlying solute clearance from the brain parenchyma remain debated, with competing hypotheses involving bulk cerebrospinal fluid flow versus perivascular transport. Using multimodal in vivo imaging and computational modeling in mice, this study demonstrates that arterial pulsation drives bidirectional solute movement within the ...

This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

ABSTRACT Background Traditional methods for evaluating split renal function, including contrast‐enhanced CT and radionuclide imaging, have limitations related to ionizing radiation or potentially nephrotoxic contrast agents. Purpose To investigate the value of renal blood flow (RBF)‐weighted estimated glomerular filtration rate (eGFR) derived from ...

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...
