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...

Calcium/calmodulin ‐dependent protein kinase kinase β is neuroprotective in stroke in aged mice
This study demonstrates that CaMKK β is neuroprotective following stroke in aged mice. Inhibition of CaMKK β worsened stroke outcome by reducing expression of prosurvival factors, as well as the levels of proteins important for the integrity of blood–brain barrier, and increasing proinflammatory cytokines in the serum after stroke. Conversely, the overexpression of CaMKK β reduced infarcts and behavioral deficits in aged mice.

Genetic deletion of calcium/calmodulin-dependent protein kinase kinase ß (CaMKK ß) or CaMK IV exacerbates stroke outcomes in ovariectomized (OVXed) female mice
Conclusions: Inhibition of CaMKK signaling exacerbated stroke outcome and increased BBB impairment, transcriptional inactivation and inflammatory responses in females after stroke. Therefore, CaMKK signaling may be a potential target for stroke treatment in both males and females.

The Epidemiology and Clinical Associations of Stroke in Patients with Acute Myeloid Leukemia: A review of 10,972 admissions from the 2012 National Inpatient Sample
Conclusions Patients with AML have an elevated risk of CVA compared to all inpatients and mortality in this population is high. Better characterization of risk factors of stroke in this vulnerable population is still needed. Teaser Acute leukemia predisposes patients toward the development of stroke. The latter, while devastating clinically, has been infrequently studied. Our study, using the 2012 National Inpatient Sample, found a 50-fold increase in the risk of stroke as compared to all inpatient admissions with a corresponding 5.5-fold increased risk of mortality. Significant risk factors for the development of stroke i...

Cryptotanshinone exhibits therapeutical effects on cerebral stroke through the PI3K/AKT ‑eNOS signaling pathway.
In conclusion, CPT exhibited a protective effect against cerebral stroke through inhibition of the PI3K/AKT‑eNOS signaling pathway. These results suggested the potential of CPT as a promising agent in the treatment of cerebral stroke. PMID: 29152647 [PubMed - as supplied by publisher]

An Integrative Pharmacology-Based Analysis of Refined Qingkailing Injection Against Cerebral Ischemic Stroke: A Novel Combination of Baicalin, Geniposide, Cholic Acid, and Hyodeoxycholic Acid
In conclusion, RQKL protected tissue against ischemic stroke through multiple-target, multiple signals, and modulating multiple cell-types in brain. This study not only promoted our understanding of the role of RQKL against ischemic stroke, but also provided a pattern for the study of Chinese medicine combining pharmaceutical Informatics and system biology methods.

Ginkgetin aglycone attenuates neuroinflammation and neuronal injury in the rats with ischemic stroke by modulating STAT3/JAK2/SIRT1.
In conclusion, data of the report reveal that treatment with Ginkgetin aglycone protects the neuronal injury against stroke in rats by reducing oxidative stress and inflammation. PMID: 31038184 [PubMed - in process]

Preclinical Evidence and Possible Mechanisms of Rhodiola rosea L. and Its Components for Ischemic Stroke: A Systematic Review and Meta-Analysis
Conclusion: The findings suggested that RRC can improve ischemia stroke. The possible mechanisms of RRC are largely through antioxidant, anti-apoptosis activities, anti-inflammatory, repressing lipid peroxidation, antigliosis, and alleviating the pathological blood brain barrier damage.

Real-World Persistence and Time to Next Treatment With Ibrutinib in Patients With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma Including Patients at High Risk for Atrial Fibrillation or Stroke
CONCLUSION: This study highlights that elevated baseline AF/stroke-related risk does not adversely impact TTD and TTNT outcomes associated with ibrutinib use. Additionally, TTNT was significantly longer for patients treated with ibrutinib vs. other regimens.PMID:35973891 | DOI:10.1016/j.clml.2022.07.004

Effects of microRNA-21 and microRNA-24 inhibitors on neuronal apoptosis in ischemic stroke.
CONCLUSION: MiRNA-24 but not miR-21 inhibitor prevents apoptosis in ischemic stroke by regulation of Bcl-xL, Caspase-3 and HSP70. PMID: 27508039 [PubMed]

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...
