Acute spinal cord injury (SCI) produces tissue damage that continues to evolve days and weeks after the initial insult, with corresponding functional impairments. Reducing the extent of progressive tissue loss ('neuroprotection') following SCI should result in a better recovery from SCI, but treatment options have thus far been limited. In this study, we(More)
The capacity of minocycline to alleviate disease for several neurological disorders in animals is increasingly being recognised. Indeed, that one drug alone can attenuate the severity of disease in stroke, multiple sclerosis, spinal-cord injury, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis is astounding. In this review, we(More)
Remyelination is a critical repair process that is initiated after a demyelinating insult. The failure to remyelinate contributes to neurological diseases such as multiple sclerosis. Here, we test the hypothesis that proteinase activity is required for the extensive remodeling of the extracellular matrix that occurs during remyelination. We show that mice(More)
We investigated the role of matrix metalloproteinases (MMPs) in acute spinal cord injury (SCI). Transcripts encoding 22 of the 23 known mammalian MMPs were measured in the mouse spinal cord at various time points after injury. Although there were significant changes in the expression levels of multiple MMPs, MMP-12 was increased 189-fold over normal levels,(More)
We investigated the role of matrix metalloproteinases (MMPs) in a mouse model of intracerebral haemorrhage (ICH). Transcripts encoding nine of the 23 known mammalian MMPs were measured. MMP-12 levels were the most elevated. To evaluate the role of MMP-12 in ICH, haemorrhages were induced in wild-type (WT) and MMP-12 null mice. The results show that MMP-12(More)
We have developed a novel multiscale localized image texture analysis technique, based upon the polar Stockwell Transform (PST). In this paper we characterized image texture in vivo using the PST in histologically verified lesion areas in T2-weighted MRI of an animal model of multiple sclerosis. Both high and low frequency signals, representing inflammation(More)
The failure of neuroprotective drugs in clinical trials has raised questions about the predictive value of animal models. To address this issue we reexamined the efficacy of clomethiazole using functional and histological outcome measures in combination with long-term survival times. Gerbils were exposed to 5 min of global ischemia and received 400 mg/ml(More)
Inflammation modulates tissue damage in relapsing-remitting multiple sclerosis (MS) both acutely and chronically, but its severity is difficult to evaluate with conventional MRI analysis. In mice with experimental allergic encephalomyelitis (EAE, a model of MS), we administered ultra small particles of iron oxide to track macrophage-mediated inflammation(More)
