      Optical Coherence Tomography Detection of Neurodegeneration in Multiple Sclerosis

      The pathophysiology of multiple sclerosis (MS) is typically characterised by inflammation and demyelination leading to neurodegeneration, which is associated with disability and the progressive stages of MS. The visual system is a valuable tool for studying neurodegeneration and potential neuroprotection in the central nervous system due to its ease of accessibility. Optical coherence tomography (OCT) is a non-invasive tool, which can be used to measure the thickness of the retinal nerve fibre layer (RNFL). The thickness of RNFL is reduced following the development of MS and optic neuritis and can therefore be used as a correlate of global axonal loss ...

      Magnetomotive Molecular Nanoprobes
      Tremendous developments in the field of biomedical imaging in the past two decades have resulted in the transformation of anatomical imaging to molecular-specific imaging. The main approaches towards imaging at a molecular level are the development of high resolution imaging modalities with high penetration depths and increased sensitivity, and the development of molecular probes with high specificity. The development of novel molecular contrast agents and their success in molecular optical imaging modalities have lead to the emergence of molecular optical imaging as a more versatile and capable technique for providing morphological, spatial, and functional information at the molecular level with ...

    3. Changes in the Expression of the Alzheimer's Disease-Associated Presenilin Gene in Drosophila Heart Leads to Cardiac Dysfunction

      Changes in the Expression of the Alzheimer's Disease-Associated Presenilin Gene in Drosophila Heart Leads to Cardiac Dysfunction
      Mutations in the presenilin genes cause the majority of early-onset familial Alzheimer's disease. Recently, presenilin mutations have been identified in patients with dilated cardiomyopathy (DCM), a common cause of heart failure and the most prevalent diagnosis in cardiac transplantation patients. However, the molecular mechanisms, by which presenilin mutations lead to either AD or DCM, are not yet understood. We have employed transgenic Drosophila models and optical coherence tomography imaging technology to analyze cardiac function in live adult Drosophila. Silencing of Drosophila ortholog of presenilins (dPsn) led to significantly reduced heart rate and remarkably age-dependent increase in end-diastolic vertical dimensions ...
