Abstract:

Stroke remains the world’s leading cause of death and disability for which no early diagnosis or effective therapies are available.
The increasing prevalence of ischemic stroke and related health risks combined with the lack of early diagnosis and effective
therapies, highlight the desperate need for continued preclinical research to understand the pathological mechanisms of this
devastating disease which may enable the development of novel therapeutic targets. However, stroke induced early events and
pathological mechanisms remain poorly understood. This is primarily due to lack of clinically relevant models that are highly
reproducible as the pathophysiology of cerebral ischemia in animal models is modulated by numerous indirect or secondary
factors including the species, type of blood vessels occluded, occlusion period and reperfusion time. We have now optimised
murine models of stroke and examined neuronal degeneration and neurochemical changes in these models. These models
show consistent pathological and neurochemical changes. In collaboration with the engineering team at the Leeds University,
we have also developed bio photonic technologies using lasers with skin safe wavelengths for detection of biomarkers in stroke.
