Neurological Instability in Ischemic Stroke: Relation with Outcome, Latency Time, and Molecular Markers.

Transl Stroke Res 2021 Jun 24. Epub 2021 Jun 24.

Clinical Neurosciences Research Laboratory, Health Research Institute of Santiago de Compostela (IDIS), 15706, Santiago de Compostela, Spain.

The National Institutes of Health Stroke Scale (NIHSS) is commonly used to evaluate stroke neurological deficits and to predict the patient's outcome. Neurological instability (NI), defined as the variation of the NIHSS in the first 48 h, is a simple clinical metric that reflects dynamic changes in the area of the brain affected by the ischemia. We hypothesize that NI may represent areas of cerebral instability known as penumbra, which could expand or reduce brain injury and its associated neurological sequels. Read More

Characterization of brain-wide somatosensory BOLD fMRI in mice under dexmedetomidine/isoflurane and ketamine/xylazine.

Sci Rep 2021 Jun 23;11(1):13110. Epub 2021 Jun 23.

Center for Neuroscience Imaging Research (CNIR), Institute for Basic Science (IBS), Suwon, 16419, South Korea.

Mouse fMRI under anesthesia has become increasingly popular due to improvement in obtaining brain-wide BOLD response. Medetomidine with isoflurane has become well-accepted for resting-state fMRI, but whether this combination allows for stable, expected, and robust brain-wide evoked response in mice has yet to be validated. We thus utilized intravenous infusion of dexmedetomidine with inhaled isoflurane and intravenous infusion of ketamine/xylazine to elucidate whether stable mouse physiology and BOLD response are obtainable in response to simultaneous forepaw and whisker-pad stimulation throughout 8 h.
