ANTICIPATORY POSTURAL CONTROL OF STABILITY DURING GAIT INITIATION OVER OBSTACLES OF DIFFERENT HEIGHT AND DISTANCE MADE UNDER REACTION-TIME AND SELF-INITIATED INSTRUCTIONS

Frontiers in Human Neuroscience, 2016
Despite the abundant literature on obstacle crossing in humans, the question of how the central nervous system (CNS) controls postural stability during gait initiation with the goal to clear an obstacle remains unclear.

Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke

Advanced Healthcare Materials, EarlyView.
In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.
