Bone Marrow Stromal Cells Combined with Oxiracetam Influences the Expression of B-cell Lymphoma 2 in Rats with Ischemic Stroke
This study aimed to investigate the combination effects of bone marrow stromal cells (BMSCs) and oxiracetam for ischemic stroke. Forty Sprague Dawley female rats (220 ± 20 g) were subjected to a 2-hour ischemic middle cerebral artery occlusion (MCAO)–24 hours reperfusion model. The rats were randomly divided into 4 groups. Rats from BMSCs group, oxiracetam group, and BMSCs + oxiracetam group accepted injection of BMSCs (3 × 106 cells), oxiracetam (800 mg/kg), and BMSCs + oxiracetam, respectively.

Cell-Based Therapies for Stroke: Promising Solution or Dead End? Mesenchymal Stem Cells and Comorbidities in Preclinical Stroke Research
Conclusion The high prevalence of comorbidities in patients with stroke indicates the need for therapies in preclinical studies that take into account these comorbidities in order to avoid failures in translation to the patient. Preclinical studies are beginning to evaluate the efficacy of MSC treatment in stroke associated with comorbidities, especially hypertension, for ischemic and hemorrhagic stroke. Regarding aging and diabetes, only ischemic stroke studies have been performed. For the moment, few studies have been performed and contradictory results are being reported. These contradictory results may be due to the u...

Vascular Endothelial Growth Factor Isoform-B Stimulates Neurovascular Repair After Ischemic Stroke by Promoting the Function of Pericytes via Vascular Endothelial Growth Factor Receptor-1
In this study, we investigated the therapeutic potential of VEGF-B in ischemic stroke using different in vivo and in vitro approaches. We showed that the delayed intranasal administration of VEGF-B reduced neuronal damage and inflammation. Unexpectedly, VEGF-B stimulated the formation of stable brain microvasculature within the injured region by promoting the interaction between endothelial cells and pericytes. Our data indicate that the effects of VEGF-B were mediated via its specific receptor VEGF receptor-1 (VEGFR-1) that is predominately expressed in brain pericytes. Importantly, VEGF-B promoted the survival of pericyt...

Serum Levels of B-cell Lymphoma-2 Anti-Apoptotic Protein and Malignant Middle Cerebral Artery Infarction Mortality
In addition to many disabilities and deaths, ischemic stroke is also responsible for a great consumption of health resources.1 Apart from the primary brain injury due to vasculature obstruction, in ischemic stroke appears a secondary brain injury due to the activation of different physiopathological pathways (as apoptosis).2 –6 Apoptotic changes have been found in brain tissue samples of patients with ischemic stroke.7–11

The Weakened Interaction Between HECTD4 and GluN2B in Ischemic Stroke Promotes Calcium Overload and Brain Injury Through a Mechanism Involving the Decrease of GluN2B and MALT1 Ubiquitination
This study explores the relationship between HECTD4, GluN2B, and MALT1, focusing on their role in brain injury in ischemic stroke. Rats were subjected to 2  h-ischemia followed by 24-h reperfusion to establish an ischemic stroke model. We observed the downregulation of HECTD4 and the upregulation of MALT1. Additionally, an increased GluN2B phosphorylation was concomitant with weakened interactions between HECTD4 and GluN2B, followed by decreased stria tal-enriched protein phosphatase (STEP61). Knockdown of HECTD4 exacerbated hypoxia- or NMDA-induced injury in nerve cells coincident with a decrease in GluN2B and MALT1 ubiq...

Diagnostic Yield and Safety of Brain Biopsy for Suspected Primary Central Nervous System Angiitis Brief Reports
Conclusions— Brain biopsy leads to pathological confirmation of vasculitis in a minority of suspected PACNS cases but alternative diagnoses are often identified. Importantly, rare but meaningful complications may occur.

Granulomatous Angiitis of the Central Nervous System Associated with Hodgkin's Lymphoma: Case Report and Literature Review
We describe the case of a patient with neurological symptoms from GACNS that led to the diagnosis of HL, as well as a literature review focusing on the association between GACNS and HL.

A Case of Recurrent Ischemic Stroke due to Intravascular Lymphomatosis, Undiagnosed by Random Skin Biopsy and Brain Imaging
We report a 68-year-old man who presented with transient ideomotor apraxia and mildly elevated soluble interleukin-2 receptor levels. He was initially diagnosed with aortogenic embolic stroke. He developed rapidly progressive neurological manifestations with enlargement of brain lesions on brain computed tomography and magnetic resonance imaging and died 3 months after symptom onset. The diagnosis of IVL could not be made by random skin biopsy, but was finally made at autopsy. For the early diagnosis, sufficient random skin biopsy or brain biopsy should be planned when suspected.Case Rep Neurol 2017;9:234 –240

Subacute Methotrexate Encephalopathy Mimicking Ischemic Stroke With Dynamic Changes on Magnetic Resonance Imaging
We report a 35-year-old woman who suddenly developed left hemiparesis and dysarthria at 13 days after treatment with intrathecal and intravenous methotrexate for intravascular large B cell lymphoma with possible central nervous system infiltration. Seven hours after onset, she developed further right hemiparesis and aphasia. However, the majority of neurologic symptoms disappeared spontaneously and completely by 34 hours. We also recorded the dynamic progression and regression of abnormal signals in the bilateral corona radiata on diffusion-weighted imaging, in parallel with neurologic symptoms.

Cryptotanshinone Attenuates Oxygen-Glucose Deprivation/ Recovery-Induced Injury in an in vitro Model of Neurovascular Unit
Conclusions Despite the above limitations, we indicate that the protective mechanism of CTs against OGD/R damage might exert via inhibiting neuron apoptosis and attenuating BBB disruption. Furthermore, we also clarified that CTs inhibited neuronal apoptosis possibly by blocking the activation of MAPK signaling pathways, and CTs alleviating BBB disruption may associated with the regulation of TJPs and MMP-9 in our experiment. Accordingly, CTs will represent a novel and potent candidate for the treatment of CIRI in the future. Ethics Statement This study was carried out in accordance with the recommendations of China�...

The Effects of Intelectin-1 on Antioxidant and Angiogenesis in HUVECs Exposed to Oxygen Glucose Deprivation
Conclusion: These results suggest intelectin-1 promotes angiogenesis, inhibits oxidative stress and reduces apoptosis by stimulating the Akt-eNOS signaling pathway in response to ischemia in vitro. Introduction Stroke is a main reason of human neurological disability, ischemic stroke (IS) accounts for almost 80–90% of all strokes. IS occurs after a cerebral blood flow disruption, leading to cellular death and tissue damage by restricting glucose and oxygen supplies (1). Ischemic vascular diseases cause substantial vascular valve and vascular endothelial cell injuries, eventually damaging the surrounding tis...
