Overexpression of Egr2 and Egr4 protects rat brains against ischemic stroke by downregulating JNK signaling pathway.
CONCLUSION: Upregulation of Egr2 and Egr4 could demote the activation of JNK/c-JUN pathway and the expression of pro-inflammatory cytokines in MCAO rats, so that Egr2 and Egr4 might be potential targets for ischemic stroke in future. PMID: 29580816 [PubMed - as supplied by publisher]

Angiopoietin-1 Mimetic Peptide Promotes Neuroprotection after Stroke in Type 1 Diabetic Rats.
CONCLUSION: Decreased neuroinflammation and reduced BBB leakage may contribute, at least in part, to vasculotide-induced neuroprotective effects after stroke in T1DM rats. PMID: 30124060 [PubMed - as supplied by publisher]

Selenium Drives a Transcriptional Adaptive Program to Block Ferroptosis and Treat Stroke
Publication date: Available online 2 May 2019Source: CellAuthor(s): Ishraq Alim, Joseph T. Caulfield, Yingxin Chen, Vivek Swarup, Daniel H. Geschwind, Elena Ivanova, Javier Seravalli, Youxi Ai, Lauren H. Sansing, Emma J. Ste.Marie, Robert J. Hondal, Sushmita Mukherjee, John W. Cave, Botir T. Sagdullaev, Saravanan S. Karuppagounder, Rajiv R. RatanSummaryFerroptosis, a non-apoptotic form of programmed cell death, is triggered by oxidative stress in cancer, heat stress in plants, and hemorrhagic stroke. A homeostatic transcriptional response to ferroptotic stimuli is unknown. We show that neurons respond to ferroptotic stimul...

A Hallmark Clinical Study of Cord Blood Therapy in Adults with Ischemic Stroke.
Abstract The therapeutic application of human umbilical cord blood cells has been an area of great interest for at least the last 25 years. Currently, cord blood cells are approved for reconstitution of the bone marrow following myeloablation in both young and old patients with myeloid malignancies and other blood cancers. Translational studies investigating alternative uses of cord blood have also shown that these cells not only stimulate neurogenesis in the aged brain but are also potentially therapeutic in the treatment of adult neurodegenerative disorders including amyotrophic lateral sclerosis, Alzheimer's di...

Stroke-Like Presentation of Paraneoplastic Cerebellar Degeneration: a Single-Center Experience and Review of the Literature
We report herein incidence and clinical features of hyperacute onset PCD, a vertebrobasilar stroke mimic. We performed a retrospective analysis of all suspected PCD cases referred to the Udine University Hospital between 2009 and 2017. Our center provides the only neuroimmunology laboratory for three provinces of the Friuli-Venezia Giulia region, Italy (983,190 people as of January 1, 2017). Inclusion criteria were (1) abrupt onset of neurological symptoms; (2) initial consideration of a vascular etiology; (3) final diagnosis of “definite PCD.” We also carried out a systematic review of the literature in order to ident...

The resolution of carotid arterial thrombus by oral anticoagulation after IV thrombolysis for chemotherapy-induced stroke: A case report
Rationale: Cancer-related stroke has been regarded as an emerging subtype of ischemic event. Acute treatment for this subtype may include the antiplatelet agents, anticoagulants, or endovascular intervention. Patient concerns: A 63-year-old woman with sudden-onset right hemiparesis and conscious change was sent to our emergency department. The patient had underlying sigmoid adenocarcinoma and received chemotherapy FOLFIRI (FOL, folinic acid; F, fluorouracil; and IRI, irinotecan) with targeted therapy cetuximab following lower anterior resection since the diagnosis was made. Diagnoses: Brain magnetic resonance angio...

Electroacupuncture Attenuates Inflammation after Ischemic Stroke by Inhibiting NF- κB-Mediated Activation of Microglia.
In this study, we observed the effects of electroacupuncture at Baihui (GV20) and Dazhui (GV14) on microglial activation and inflammation in the cortical ischemic penumbra (IP) of permanent middle cerebral artery occlusion (pMCAO) rats. It was found that electroacupuncture inhibited the degeneration and necrosis of microglia in the cortical IP and ameliorated mitochondrial damage. Immunofluorescence and western blot analysis showed that microglia were in a resting state or weakly activated in the normal brain. After cerebral ischemia, the expression of microglial markers (Iba-1 and CD11b) increased, and NF-κB p65, IL-1β,...

Embolic Stroke Due to a Mural Thrombus in the Ascending Aorta Following Cisplatin-based Chemotherapy.
Authors: Ochiai Y, Tsunogae M, Ueda M Abstract A 59-year-old woman with small-cell lung carcinoma achieved tumor disappearance after cisplatin-based chemotherapy (CBC) and radiation treatment but subsequently experienced right hemiparesis and aphasia. Brain magnetic resonance imaging revealed a left middle cerebral artery territory acute infarction and left internal carotid artery occlusion. Ultrasonography revealed a mobile thrombus in the left common and internal carotid arteries, and contrast computed tomography revealed a mural thrombus in the ascending aorta. Based on these findings, embolic stroke due to aort...

Isolation and Purification of Self-Renewable Human Neural Stem Cells from iPSCs for Cell Therapy in Experimental Model of Ischemic Stroke
Methods Mol Biol. 2022;2389:165-175. doi: 10.1007/978-1-0716-1783-0_14.ABSTRACTNeural stem cell therapy has been galvanized by the discovery of pluripotent stem cells. The possibility to generate specialized central nervous system-specific differentiated cells using human somatic cells engineered to become induced pluripotent stem cells (iPSCs) was a game changer. This technology has broad applications in the field of regenerative medicine, in vitro disease modeling, targeted drug discovery, and precision medicine. Currently, iPSCs are one of the most promising cell sources amenable for commercialization and off-the-shelf ...

Cerebral Perfusion in Pediatric Stroke: Children Are Not Little Adults
Cerebral perfusion imaging provides useful information about the hemodynamic state of the brain that is relevant to a number of neurologic conditions, including stroke, epilepsy, and brain tumors. Multiple imaging modalities have been developed to evaluate brain perfusion, primarily by the use of different tracers to measure cerebral blood volume and cerebral blood flow. Here, we provide an overview of magnetic resonance imaging perfusion techniques; summarize the role of perfusion imaging in adult stroke; describe changes in cerebral blood flow over childhood; and discuss the relevance and future directions of perfusion i...

Electroacupuncture promotes microglial M2 polarization in ischemic stroke via annexin A1
CONCLUSION: The current study provides strong evidence that EA treatment has protective effects against ischemic stroke in the MCAO/R mouse model and that the mechanism likely involves the promotion of M2 polarization in microglia via ANXA1.PMID:34894768 | DOI:10.1177/09645284211057570
