Non-Invasive Mitochondrial Modulation With Near-Infrared Light Reduces Brain Injury After Stroke, Christos Dionisos Strubakos

Wayne State University Dissertations

Acute ischemic stroke is a debilitating disease that causes significant brain injury.

While rapid restoration of blood flow is critical to salvage the ischemic brain, reperfusion

of tissue can further drive brain damage by inducing generation of mitochondrial reactive

oxygen species (Chouchani et al., 2014a). Recent studies by our group found that noninvasive

mitochondrial modulation (NIMM) with near-infrared (NIR) light can limit the

production of reactive oxygen species following global brain ischemia (T. H. Sanderson

et al., 2018). NIR interacts with the rate limiting step of the mitochondrial electron

transport chain (ETC), cytochrome c oxidase (COX), and modulates mitochondrial

respiration. …

Abstract

Background

The primary goal of this study was to investigate the relationship between increasing output power levels and clot fragmentation during high-intensity focused ultrasound (HIFU)-induced thrombolysis.

Methods

A HIFU headsystem, designed for brain applications in humans, was used for this project. A human calvarium was mounted inside the water-filled hemispheric transducer. Artificial thrombi were placed inside the skull and located at the natural focus point of the transducer. Clots were exposed to a range of acoustic output power levels from 0 to 400 W. The other HIFU operating parameters remained constant. To assess clot fragmentation, three filters of different …
