Rhein attenuates cerebral ischemia-reperfusion injury via inhibition of ferroptosis through NRF2/SLC7A11/GPX4 pathway
CONCLUSION: Rhein attenuates cerebral I/R injury by inhibiting ferroptosis via the NRF2/SLC7A11/GPX4 axis, highlighting its potential as a therapeutic agent for ischemic stroke.PMID:37714424 | DOI:10.1016/j.expneurol.2023.114541

Recombinant Human Perlecan DV and Its LG3 Subdomain Are Neuroprotective and Acutely Functionally Restorative in Severe Experimental Ischemic Stroke
AbstractDespite recent therapeutic advancements, ischemic stroke remains a major cause of death and disability. It has been previously demonstrated that  ~ 85-kDa recombinant human perlecan domain V (rhPDV) binds to upregulated integrin receptors (α2β1 and α5β1) associated with neuroprotective and functional improvements in various animal models of acute ischemic stroke. Recombinant human perlecan laminin-like globular domain 3 (rhPDVLG3), a 21-kDa C-terminal subdomain of rhPDV, has been demonstrated to more avidly bind to the α2β1 integrin receptor than its parent molecule and consequently was postulated to evok...

Early Hyperchloremia is Independently Associated with Death or Disability in Patients with Intracerebral Hemorrhage
ConclusionsThe independent association between hyperchloremia and death or disability at 90  days suggests that avoidance of hyperchloremia may reduce the observed death or disability in patients with ICH.Clinical Trial RegistrationClinicalTrials.gov: NCT01176565.

Inhibition of LncRNA MALAT1 Attenuates Cerebral Ischemic Reperfusion Injury via Regulating AQP4 Expression
Stroke is one of the leading causes of mortality and disability worldwide. Long noncoding RNAs (lncRNAs) including MALAT1 have been shown to have critical roles in cerebral ischemia reperfusion injury (CIRI). However, the underlying mechanism of MALAT1 in CIRI has not been elucidated. The present study aimed to investigate the function and potential regulatory mechanism of MALAT1 in cerebral ischemic reperfusion injury. We established the middle cerebral artery occlusion (MCAO) model and oxygen-glucose deprivation/reoxygenation (OGD/RX) model in vivo and in vitro, and then Cell Counting Kit-8 (CCK-8), RT-qPCR, flow cytomet...

Flinders Sensitive Line rats are resistant to infarction following transient occlusion of the middle cerebral artery.
CONCLUSIONS: Our study suggests that the rat strain does not influence infarct volumes following MCAo. PMID: 32194078 [PubMed - as supplied by publisher]

Bumetanide: A review of its neuroplasticity and behavioral effects after stroke.
Authors: Tao D, Liu F, Sun X, Qu H, Zhao S, Zhou Z, Xiao T, Zhao C, Zhao M Abstract Stroke often leads to neuronal injury and neurological functional deficits. Whilst spontaneous neurogenesis and axon regeneration are induced by ischemic stroke, effective pharmacological treatments are also essential for the improvement of neuroplasticity and functional recovery after stroke. However, no pharmacological therapy has been demonstrated to be able to effectively improve the functional recovery after stroke. Bumetanide is a specific Na +-K +-Cl- co-transporter inhibitor which can maintain chloride homeostasis in neuro...

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...
