Imaging Iron Content In Patients With Multiple Sclerosis Using Magnetic Resonance Imaging, Charbel Abdo Habib
Wayne State University Dissertations
The importance of iron in maintaining normal physiological processes in the human body has been well emphasized in the literature. However, "when iron behaves badly", its abnormal presence might lead to a spectrum of pathologies depending on what function has been altered. In the brain, for instance, abnormal iron content is thought to be associated with neurodegenerative diseases. In this dissertation, we study iron involvement in one of the most debilitating neurological diseases, multiple sclerosis (MS), using in vivo magnetic resonance imaging. We first test the sensitivity and specificity of the MR method used, known as susceptibility weighted imaging (SWI) …

Cardiolipin (CL) is the signature phospholipid of mitochondrial membranes, where it is synthesized locally and plays a critical role in mitochondrial bioenergetic functions. Inside the mitochondria, CL is a critical target of mitochondrial generated reactive oxygen species (ROS) and regulates signaling events related to apoptosis and aging. CL deficiency causes perturbation of signaling pathways outside the mitochondria, including the PKC-Slt2 cell integrity pathway and the high osmolarity glycerol (HOG) pathway, and is a key player in the cross-talk between the mitochondria and the vacuole. The importance of CL in human health is underscored by the observation that perturbation of CL …
