Cerebral Hyperperfusion Syndrome Risk Comparison between Transcarotid Artery Revascularization and Carotid Artery Stenting with Distal Embolic Protection.
Ann Vasc Surg

Background: Cerebral hyperperfusion syndrome (CHS) is a rare but serious complication after carotid artery revascularization. This study aims to determine the impact of carotid artery stenting (CAS) modality on the incidence, severity and overall outcomes of CHS after carotid revascularization.
Methods: Data from patients who underwent CAS with either distal embolic protection (CAS+DEP) or transcarotid artery revascularization (TCAR) were obtained from the Vascular Quality Initiative (VQI) database 2016-2023.
A cis-regulatory element controls expression of histone deacetylase 9 to fine-tune inflammasome-dependent chronic inflammation in atherosclerosis.

Electronic address:
Common genetic variants in a conserved cis-regulatory element (CRE) at histone deacetylase (HDAC)9 are a major risk factor for cardiovascular disease, including stroke and coronary artery disease. Given the consistency of this association and its proinflammatory properties, we examined the mechanisms whereby HDAC9 regulates vascular inflammation. HDAC9 bound and mediated deacetylation of NLRP3 in the NACHT and LRR domains leading to inflammasome activation and lytic cell death.

Electronic address:
Ischemic stroke is a very common brain disorder. This study aims to assess the neuroprotective effects of piceatannol (PCT) in preventing neuronal injury resulting from cerebral ischemia and reperfusion (I/R) in mice. Additionally, we investigated the underlying mechanisms through which PCT inhibits neuronal ferroptosis by modulating the USP14/GPX4 signaling axis.

Royal United Hospital, Combe Park, Bath, Avon, BA1 3NG, UK.
Objectives: Artificial intelligence (AI) software including Brainomix "e-CTA" which detect large vessel occlusions (LVO) have clinical potential. We hypothesised that in real world use where prevalence is low, its clinical utility may be overstated.
Methods: In this single centre retrospective service evaluation project, data sent to Brainomix from a medium size acute National Health Service (NHS) Trust hospital between 1/3/2022-1/3/2023 was reviewed.
Prolonged sitting is not associated with altered shear-mediated dilation of the internal carotid artery, despite impairing lower limb endothelial function.
Physiol Rep

Department of Biomedical Engineering, Toyo University, Saitama, Japan.
The present study aims to examine the effect of 4 h of continuous sitting on cerebral endothelial function, which is a crucial component of cerebral blood flow regulation. We hypothesized that 4 h of sitting may impair cerebral endothelial function similarly to how it affects lower limb vasculature. Thirteen young, healthy participants were instructed to remain seated for 4 h without moving their lower limbs.
