Intrathecal injection of aptamer-conjugated DNA framework for the treatment of cerebral ischemia/reperfusion injury.
Conclusion: The high payload of an aptamer conjugated bipyramidal FNA was for cerebral IRI management was provided by intrathecal injection. This DNA framework alleviated the extent of cerebral IRI by acting as an antioxidant and inhibitor of inflammation.

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.

Molecular imaging of inflammation in the brain-heart axis after ischemic stroke: comparison of two murine stroke models.
Conclusions: In contrast to topical ET-1 application after craniotomy, the intravascular MCAo model enables imaging studies of brain-heart networking after stroke, which evokes elevated TSPO PET signal in both brain and heart. The severity of cerebral ischemic damage may contribute to cardiac dysfunction via systemic inflammatory networking.

Antioxidative neuroprotective role of iron-gallic acid coordination nanoparticles and PET/MR usage in an ischemia stroke model
Conclusions: Fe-GA CPNs exhibit an impressive antioxidative neuroprotective role in ischemia stroke, which might have the potential to be translated into clinical applications for improved treatment of patients with stroke. PET/MRI is effective and accurate method for ischemic evaluation.
