Upper Limb Recovery After Stroke Is Associated With Ipsilesional Primary Motor Cortical Activity: A Meta-Analysis Clinical Sciences
Conclusions— Activity in ipsilesional primary motor and medial-premotor cortices in chronic stroke signals good motor recovery, whereas cerebellar vermis activity signals poor recovery. Functional MRI may be useful in identifying recovery biomarkers.

Influence of Amyloid-{beta} on Cognitive Decline After Stroke/Transient Ischemic Attack: Three-Year Longitudinal Study Clinical Sciences
Conclusions— Compared with subjects without Alzheimer’s disease–like Aβ deposition, those with Aβ deposition experienced a more severe and rapid cognitive decline over 3 years after stroke/transient ischemic attack. Aβ was associated with changes in multiple cognitive domains.

Comparison of the 2 Most Popular Deconvolution Techniques for the Detection of Penumbral Flow in Acute Stroke Clinical Sciences
Conclusions— Block-circulant single value decomposition seems only significantly beneficial for mean transit time maps in (sub)acute stroke. Tmax is likely the most stable deconvolved parameter for the detection of tissue-at-risk using DSC-MRI.

Integrin {alpha}4 Overexpression on Rat Mesenchymal Stem Cells Enhances Transmigration and Reduces Cerebral Embolism After Intracarotid Inȷection Brief Report
Conclusions—ITGA4 overexpression on MSCs enhances transendothelial migration in vitro, but not in vivo, although it improves safety after intracarotid transplantation into stroke rats.

Effects of Noninvasive Brain Stimulation on Language Networks and Recovery in Early Poststroke Aphasia Clinical Sciences
Conclusions— Ten sessions of inhibitory rTMS over the right posterior inferior frontal gyrus, in combination with speech and language therapy, significantly improve language recovery in subacute ischemic stroke and favor recruitment of left-hemispheric language networks.

123I-Iomazenil Single Photon Emission Computed Tomography Visualizes Recovery of Neuronal Integrity by Bone Marrow Stromal Cell Therapy in Rat Infarct Brain Basic Sciences
Conclusions— The present findings strongly suggest that the BMSCs may enhance functional recovery by improving the neuronal integrity in the peri-infarct area, when directly transplanted into the infarct brain at clinically relevant timing. 123I-IMZ single photon emission computed tomography may be a promising modality to scientifically prove the beneficial effects of BMSC transplantation on the host brain in clinical situation.

Combined 18F-FDG PET-CT and DCE-MRI to Assess Inflammation and Microvascularization in Atherosclerotic Plaques Brief Reports
Conclusions— There is a weak but significant positive correlation between inflammation on positron emission tomography/computed tomography and neovascularization as assessed with dynamic contrast–enhanced-MRI. Future studies should investigate which imaging modality has the highest predictive value for recurrent stroke, as these are not interchangeable. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00451529.

De Novo Ivy Sign Indicates Postoperative Hyperperfusion in Moyamoya Disease Brief Reports
Conclusions— In MMD, a de novo ivy sign could indicate postoperative hyperperfusion after bypass, which is not always correlated with preoperative hemodynamic impairment. Additional factors other than preoperative cerebral hemodynamics might be involved in postoperative hyperperfusion in MMD.

Monitoring Neuroprotective Effects Using Positron Emission Tomography With 11CITMM, a Radiotracer for Metabotropic Glutamate 1 Receptor Basic Sciences
Conclusions— [11C]ITMM-PET may be a useful technique for characterizing the change in mGlu1 level during the occurrence and progression of neuronal damage and for evaluating the neuroprotective effects of drugs after ischemia.

Effects of Surgical Revascularization on Cerebral Oxygen Metabolism in Patients With Moyamoya Disease: An 15O-Gas Positron Emission Tomographic Study Clinical Sciences
Conclusions— Cerebral oxygen metabolism is significantly depressed in 80% of the involved hemispheres of moyamoya disease and improves in pediatric and younger adult patients without parenchymal lesions after bypass surgery. Cerebral oxygen metabolism may be reversibly depressed in response to cerebral ischemia in them although the underlying mechanisms are still unclear.
