Anxiety in Patients With Acute Ischemic Stroke: Risk Factors and Effects on Functional Status
Conclusion: Depressive symptoms are the major correlates of PSA while more severe PSA is associated with poorer ADL and health-related QOL. Acute lesions involving CHWM may correlate with PSA in ischemic stroke patients with mild-to-moderate neurologic deficits, supporting a lesion-location hypothesis in PSA.IntroductionAnxiety is prevalent after stroke and occurs in about one-quarter of stroke survivors (1, 2). Poststroke anxiety (PSA) may have a negative impact on quality of life (QOL) of stroke survivors, affecting their rehabilitation (3). Furthermore, one prospective study found that severe anxiety symptoms were assoc...

Mediterranean diet: The role of long-chain ω-3 fatty acids in fish; polyphenols in fruits, vegetables, cereals, coffee, tea, cacao and wine; probiotics and vitamins in prevention of stroke, age-related cognitive decline, and Alzheimer disease.
Authors: Román GC, Jackson RE, Gadhia R, Román AN, Reis J Abstract The mechanisms of action of the dietary components of the Mediterranean diet are reviewed in prevention of cardiovascular disease, stroke, age-associated cognitive decline and Alzheimer disease. A companion article provides a comprehensive review of extra-virgin olive oil. The benefits of consumption of long-chain ω-3 fatty acids are described. Fresh fish provides eicosapentaenoic acid while α-linolenic acid is found in canola and soybean oils, purslane and nuts. These ω-3 fatty acids interact metabolically with ω-6 fatty acids mainly linoleic...

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.

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.

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...

Is Selenium Supplementation Beneficial in Acute Ischemic Stroke?
This study proposed to investigate the effect of intravenous Se (Selenase) administration in patients with acute ischemic stroke (AIS) on neurological outcomes, antioxidant enzyme activity, and inflammatory marker levels. Methods: AIS patients (n=50) were recruited from a neurology unit of a university-affiliated hospital. Patients were randomly assigned to receive either Selenase or placebo (saline) for 5 days. The modified ranking scale, the national institute of health stroke scale, and the mini-mental state examination, as primary outcomes, and the serum GPx concentration, total antioxidant activity, and tumor n...

Polyoxometalate nanoclusters act as broad-spectrum antioxidants to alleviate ischemic stroke by intrathecal injection
Conclusion: Intrathecal injection significantly improved the delivery and efficacy of POM nanoclusters to the brain, resulting in the rapid accumulation of POM nanoclusters in the ischemic penumbra. Due to this, we confirmed that the POM nanoclusters could be used as nano-antioxidants to inhibit oxidative stress as well as inflammatory damage effectively.

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�...

Orally Administered Crocin Protects Against Cerebral Ischemia/Reperfusion Injury Through the Metabolic Transformation of Crocetin by Gut Microbiota
Conclusion Collectively, pharmacokinetic and pharmacodynamic association studies provide evidence that the gut microbiota plays a vital role in the fate of crocin and crocetin in the gastrointestinal tract. In addition, the cross-interaction between gut microbiota and crocin might mediate the activation of the cerebral-protective effect of orally administered crocin. Ethics Statement This study was carried out in accordance with the recommendations of ‘Institutional Animal Research Committee guidelines, Animal Ethics Committee of China Pharmaceutical University.’ The protocol was approved by the ‘An...

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...

Carnosol Inhibits Cerebral Ischemia-Reperfusion Injury by Promoting AMPK Activation
CONCLUSION: Carnosol has a protective effect on ischemic stroke, and this effect is achieved through AMPK activation. Our study demonstrates the protective effect of carnosol on cerebral ischemia-reperfusion injury and provides a new perspective for the clinical treatment of ischemic stroke.PMID:36775042 | DOI:10.1016/j.brainresbull.2023.02.003

CTRP9 ameliorates cellular senescence via PGC ‑1α/AMPK signaling in mesenchymal stem cells.
CTRP9 ameliorates cellular senescence via PGC‑1α/AMPK signaling in mesenchymal stem cells. Int J Mol Med. 2018 May 09;: Authors: Li Q, Zhu Z, Wang C, Cai L, Lu J, Wang Y, Xu J, Su Z, Zheng W, Chen X Abstract Stroke is the second most common cause of death worldwide, and thus, it imposes great financial burdens on both individuals and society. Mesenchymal stem cell (MSC) therapy is a promising approach for ischemic brain injury. However, MSC treatment potential is progressively reduced with age, limiting their therapeutic efficacy for brain repair post‑stroke. C1q and tumor necrosis factor‑relat...

Is Aberrant Reno-Renal Reflex Control of Blood Pressure a Contributor to Chronic Intermittent Hypoxia-Induced Hypertension?
This study demonstrated unaltered vascular conductance in response to lumbar sympathetic stimulation in CIH-exposed rats. Aortic compliance was increased and estimated blood volume was unchanged in CIH-exposed rats. Increased blood pressure was related to an increase in cardiac output, which was confirmed by echocardiography (Lucking et al., 2014). It is suggested therefore that hypertension in the CIH model can be evoked by over-excitation of the cardiac arm of sympathetic nervous system (SNS), even before mechanisms of enhanced peripheral vasoconstriction and endothelial dysfunction are initiated (Naghshin et al., 2009)....

Anti-inflammatory efficacy of Berberine Nanomicelle for improvement of cerebral ischemia: formulation, characterization and evaluation in bilateral common carotid artery occlusion rat model
CONCLUSION: Our experimental data show that pretreated groups in different doses (nano BBR 100, 75, 50 mg/kg, and BBR 100 mg/kg) successfully showed decreased levels of the inflammatory factors in cerebral ischemia compared with the stroke group and pretreated group with nano BBR in the dose of 25 mg/kg. Nano BBR formulation with a lower dose can be a better candidate than conventional BBR formulation to reduce oxidative and inflammatory factors in cerebral ischemia. Therefore, BBR-loaded micelle formulation could be a promising protective agent on cerebral ischemia.PMID:34600570 | DOI:10.1186/s40360-021-00525-7
