Article Abstract
Aims: This study aimed to investigate the correlation between clot composition and stroke mechanisms in patients undergoing endovascular therapy (EVT), using proteomic analysis.
Methods: This study included 35 patients with ischemic stroke (cardioembolism [CE], n = 17; large artery atherosclerosis [LAA], n = 6; cancer-related [CR], n = 4; and undetermined (UD) cause, n = 8) who underwent EVT. Retrieved clots were proteomically analyzed to identify differentially expressed proteins associated with the three stroke mechanisms and to develop the machine learning model.
Results: In the discover stage, 3838 proteins were identified using clot samples from 27 patients with CE, LAA, and CR mechanisms. Through functional enrichment and network analysis, 149 proteins were identified as potential candidates for verification studies. After verification experiments, 34 proteins were selected as the final candidates to predict stroke mechanisms. Furthermore, the machine learning-based model identified three proteins associated with each mechanism (Pleckstrin in CE; CD59 glycoprotein in LAA; and Immunoglobulin Heavy Constant Gamma 1 in CR) in the UD group.
Conclusions: This study identified specific protein markers of clots that could differentiate stroke mechanisms in patients undergoing EVT. Therefore, our results could offer valuable insights into elucidating the mechanisms of ischemic stroke, which could provide information on more effective secondary prevention strategies.

Background: Stroke persists as the second leading global cause of mortality and disability. We analyzed G20 nations using Global Burden of Disease (GBD) 2021 data (1990-2021) to provide a new perspective.
Methods: We obtained age-standardized rates (ASR) of stroke mortality, incidence, prevalence, and YLLs (years of life lost) across G20 nations.
Right hemisphere language network plasticity in aphasia.

The role of the right hemisphere in aphasia recovery has been controversial since the 19th century. Imaging studies have sometimes found increased activation in right hemisphere regions homotopic to canonical left hemisphere language regions, but these results have been questioned due to small sample sizes, unreliable imaging tasks, and task performance confounds that affect right hemisphere activation levels even in neurologically healthy adults. Several principles of right hemisphere language recruitment in aphasia have been proposed based on these studies: that the right hemisphere is recruited primarily by individuals with severe left hemisphere damage, that transcallosal disinhibition results in recruitment of right hemisphere regions homotopic to the lesion, and that increased right hemisphere activation diminishes to baseline levels over time.

Environmental noise, particularly from road, rail, and aircraft traffic, is now firmly recognized as a widespread risk factor for cardiovascular disease. About 1 in 3 Europeans is exposed to chronic noise exposure above the guideline thresholds recommended by the World Health Organization (WHO), thus contributing substantially to cardiovascular morbidity and mortality. Robust evidence from recent meta-analyses links transportation noise to ischemic heart disease, heart failure, stroke, hypertension, and type 2 diabetes mellitus.

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: Remote ischemic conditioning (RIC), a novel neuroprotective therapy, has broad potential for reducing the occurrence and recurrence of cerebrovascular events, yet its mechanisms are not incompletely understood. The aim of this study is to investigate whether RIC alleviates apoptosis, inflammation, and reperfusion injury in rat models of ischemic stroke by regulating the Elabela (ELA)-apelin-Apelin receptor (APJ) system.
Methods: We established a rat model of middle cerebral artery occlusion (MCAO) with ischemia-reperfusion injury, and RIC was administered twice daily for 3 days post-MCAO.
