Tunable Bessel beam two-photon fluorescence microscopy for high-speed volumetric imaging of brain dynamics

This paper introduces tunable Bessel beam two-photon fluorescence microscopy for high-speed volumetric brain imaging, demonstrating its use in mapping cerebral blood flow, neurovascular coupling, and neuroimmune responses.

OPTRACE: Optical Imaging Guided Transplantation and Tracking of Cells in the Mouse Brain

OPTRACE improves cell transplantation and tracking in the mouse brain using real-time visualization and longitudinal monitoring to study engraftment dynamics.

Real-time in vivo imaging of rodent brain response to hypoperfusion enabled by remotely controlled elastomeric micro-balloons

This paper develops micro-balloons to control blood flow in mice, enabling real-time in vivo brain imaging during hypoperfusion to study stroke pathophysiology.

Intravital Multimodal Imaging of Human Cortical Organoids for Chronic Stroke Treatment in Mice

This paper develops a multimodal imaging platform to track human cortical organoids in mice after stroke, showing their survival and maturation in specific brain regions.

A primeval mechanism of tolerance to desiccation based on glycolic acid saves neurons from ischemia in mammals by reducing intracellular calcium-mediated excitotoxicity

This study shows that glycolic acid protects neurons from ischemic damage by reducing calcium-mediated excitotoxicity during reperfusion in stroke models.
