Background: Acute ischemic stroke (AIS) ranks among the most prevalent cerebrovascular conditions. The clinical interest lies in utilizing oxidative stress (OS) markers and antioxidant system indicators for diagnosing and predicting stroke development. Our objective was to identify a precise marker of antioxidant stress ability to assess neurofunctional alterations in AIS patients.
Methods: A total of 66 AIS patients, 33 of whom also had type 2 diabetes mellitus (T2DM), were selected for our study, and 30 patients without AIS and diabetes were used as controls. The total plasma homocysteine (Hcy) concentrations were determined via an enzymatic cycling assay. The reduced Hcy to oxidised Hcy concentration ratio (Hcy/HHcy) was determined using hollow fibre centrifugal ultrafiltration (HFCF-UF) technique we previously established.
Results: The Hcy/HHcy was significantly lower in AIS patients with T2DM compared with both controls (P = 0.0262) and AIS patients without T2DM (P = 0.0468). A positive correlation was found between total Hcy concentration and the National Institutes of Health Stroke Scale (NIHSS) score (P = 0.002, r = 0.561), while no correlation was observed in AIS patients without T2DM (P = 0.850, r=-0.034). In AIS patients, the Hcy/HHcy showed a positive correlation with the NIHSS score in those with T2DM (P = 0.037, r = 0.365) and a negative correlation in those without T2DM (P = 0.003, r=-0.497). In AIS patients with T2DM, the receiver operating characteristic's area under the curve (ROC-AUC) value for total Hcy concentration was 0.796, compared to 0.600 in those without T2DM. Furthermore, the ROC-AUC values of the Hcy/HHcy were 0.719 and 0.735 in AIS patients with and without T2DM, respectively.
Conclusion: Hcy/HHcy is anticipated to serve as a precise indicator for assessing antioxidant stress ability and evaluating neurofunctional alterations in AIS patients.

The role of intravenous thrombolysis (IVT) in patients with tandem lesions (TL) undergoing endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) remains a subject of ongoing debate. The substantial clot burden and the potential need for periprocedural antiplatelet therapy during emergent carotid stenting (CAS) add to the complexity of treatment decisions. This study aims to systematically review and meta-analyze the literature to evaluate the comparative safety and efficacy of IVT plus EVT versus EVT alone in AIS patients with TL.

Large vessel occlusion (LVO)-induced acute ischemic stroke (AIS) manifests with abrupt onset and critical severity, primarily caused by cerebral artery atherosclerosis or cardiogenic embolism leading to luminal stenosis or occlusion. The authors report a case of acute massive cerebral infarction caused by occlusion of the left middle cerebral artery (MCA) and missed the time window for thrombolysis, in which spontaneous recanalization of the MCA was achieved after 1 week of conservative treatment. After 2 months of rehabilitation training, neurological functions and other symptoms significantly improved.

Background: Recent trials of large core thrombectomy have shown that our traditional understanding of infarct characteristics and reperfusion benefit may be incomplete for patients with acute ischemic stroke (AIS). The Alberta Stroke Program Early CT Score (ASPECTS) has wide inter-rater variability, and modern studies have also shown that reperfusion therapies can benefit some patients regardless of the ASPECTS. Reproducible imaging metrics that account for the degree of hypo-attenuation on non-contrast computed tomography (NCCT) may be better suited to guide treatments.

Globally, millions of individuals suffer from infectious diseases, which are major public health concerns caused by bacteria, fungi, viruses, or parasites. These diseases can be transmitted directly or indirectly from person to person, potentially leading to a pandemic or epidemic. Several advancements have been made in molecular genetics for infectious disease management, which include pharmaceutical chemistry, medicine, and infection tracking; however, these advancements still lack control over human infections.

Background: microRNA-494 (miRNA-494) plays a key role in neuroinflammation following cerebral ischemia. We aimed to assess miRNA-494 levels as a biomarker for predicting acute ischemic stroke (AIS) severity and outcomes.
Methods: miRNA-494 levels in peripheral lymphocytes were measured using reverse transcription-quantitative polymerase chain reaction.
