Ischemic core volume is associated with hemorrhagic transformation post endovascular thrombectomy.

Introduction: Symtomatic hemorrhagic transformation(sHT) was defined as any intracerebral hemorrhage that combined with clinical deterioration. While recent studies showed low rates of sHT in large core ischemic strokes treated with endovascular thrombectomy (EVT), the specific impact of core size on overall hemorrhagic transformation (HT) remains unclear. We aim to investigate the relationship between ischemic core size and development of HT post thrombectomy.

FUS Selectively Facilitates circRNAs Packing into Small Extracellular Vesicles within Hypoxia Neuron.

Small extracellular vesicles (sEVs) contain abundant circular RNAs (circRNAs) and are involved in cellular processes, particularly hypoxia. However, the process that packaging of circRNAs into neuronal sEVs under hypoxia is unclear. This study revealed the spatial mechanism of the Fused in Sarcoma protein (FUS) that facilitates the loading of functional circRNAs into sEVs in hypoxia neurons.

Increased retinal venule diameter as a prognostic indicator for recurrent cerebrovascular events: a prospective observational study.

Microvasculature of the retina is considered an alternative marker of cerebral vascular risk in healthy populations. However, the ability of retinal vasculature changes, specifically focusing on retinal vessel diameter, to predict the recurrence of cerebrovascular events in patients with ischemic stroke has not been determined comprehensively. While previous studies have shown a link between retinal vessel diameter and recurrent cerebrovascular events, they have not incorporated this information into a predictive model.

FUS-mediated HypEVs: Neuroprotective effects against ischemic stroke.

Few studies have investigated the properties and protein composition of small extracellular vesicles (sEVs) derived from neurons under hypoxic conditions. Presently, the extent of the involvement of these plentiful sEVs in the onset and progression of ischemic stroke remains an unresolved question. Our study systematically identified the characteristics of sEVs derived from neurons under hypoxic conditions (HypEVs) by physical characterization, sEV absorption, proteomics and transcriptomics analysis.

N-acetyl-L-leucine protects MPTP-treated Parkinson's disease mouse models by suppressing Desulfobacterota via the gut-brain axis.

Parkinson's disease (PD) is the second most common neurodegenerative disease, and communication between the gut and brain (the gut-brain axis) has been found to be essential in behavior and cognitive function. However, the exact mechanisms underlying microbiota dysbiosis in PD progression have not yet been elucidated. Our study aimed to investigate the correlation between gut microbiota disturbances and feces metabolic disorders in PD.

Case report: Intensive statin and PCSK-9 inhibitor combo reduces plaque volume and stenosis in ischemic stroke patient.

Intracranial atherosclerotic ischemic stroke dramatically impacts the quality of life among the elderly. Statins therapy has been proven to be effective in plaque stabilization and alleviation in patients with intracranial atherosclerotic ischemic stroke. According to recent studies, these effects may be directly related to lipid levels rather than specific lipid-lowering drugs.

We aimed to evaluate the efficacy and safety of NBP in patients with non-disabling minor ischemic stroke and transient ischemic attack (TIA). The BRIDGE (the observation study on clinical effectiveness of NBP on patients with non-disabling ischemic cerebrovascular disease) is a prospective registry to monitor the efficacy and safety of NBP therapy in acute non-disabling ischemic stroke or high-risk TIA.

Comparative Study of Multi-Delay Pseudo-Continuous Arterial Spin Labeling Perfusion MRI and CT Perfusion in Ischemic Stroke Disease.

With the aging population, stroke has gradually become the leading cause of death and disability among adults. It is necessary to verify whether multi-delay pseudo-continuous arterial spin labeling (pCASL) MRI can be used as a standard neuroimaging protocol in the patients with ischemic stroke. We aimed to investigate the clinical utility of multi-delay pCASL for evaluating cerebral perfusion in ischemic stroke disease.

Retinal Microvascular Changes in Subtypes of Ischemic Stroke.

Retinal microvasculature shares prominent similarities with the brain vasculature. We aimed to assess the association between retinal microvasculature and subtypes of ischemic stroke. We consecutively enrolled ischemic stroke patients within 7 days of onset, who met the criteria of subtype of atherothrombosis (AT), small artery disease (SAD), or cardioembolism (CE) according to a modified version of the Trial of Org 10172 in Acute Stroke Treatment (NEW-TOAST).

Blood pressure variability estimated by ARV is a predictor of poor short-term outcomes in a prospective cohort of minor ischemic stroke.

Prior studies have shown that patients with minor ischemic stroke have substantial disability rates at hospital discharge. We sought to determine whether blood pressure variability (BPV) estimated by average real variability (ARV) is one of the predictors of poor outcome at 90 days. Four hundred fifty-one consecutive patients with ischemic stroke treated within 7 days after onset were enrolled prospectively.

Association of aquaporin‑1 with tumor migration, invasion and vasculogenic mimicry in glioblastoma multiforme.

The present study aimed to assess the expression and functional role of aquaporin-1 (AQP1) in glioblastoma multiforme (GBM) migration, invasion and vasculogenic mimicry (VM). In the primary human gliomas and human glioma‑derived cell lines tested, it was observed that the expression of AQP1 was upregulated. In addition, it was demonstrated that silencing of AQP1 expression resulted in decreased migration and invasion, in addition to vasculogenic mimicry in vitro.
