Multidelay ASL of the pediatric brain
Br J Radiol. 2022 Apr 22:20220034. doi: 10.1259/bjr.20220034. Online ahead of print.ABSTRACTArterial spin labeling (ASL) is a powerful noncontrast MRI technique for evaluation of cerebral blood flow (CBF). A key parameter in single-delay ASL is the choice of postlabel delay (PLD), which refers to the timing between the labeling of arterial free water and measurement of flow into the brain. Multidelay ASL (MDASL) utilizes several PLDs to improve the accuracy of CBF calculations using arterial transit time (ATT) correction. This approach is particularly helpful in situations where ATT is unknown, including young subjects and...

Electroacupuncture promotes microglial M2 polarization in ischemic stroke via annexin A1
CONCLUSION: The current study provides strong evidence that EA treatment has protective effects against ischemic stroke in the MCAO/R mouse model and that the mechanism likely involves the promotion of M2 polarization in microglia via ANXA1.PMID:34894768 | DOI:10.1177/09645284211057570
