Mapping Of Cortical Motor Reorganization In Spinal Cord Injury, Leonid Rozhkov

Theses and Dissertations (ETD)

The annual incidence of spinal cord injury (SCI), not including those who die at the scene of the accident, is approximately 10,000 new cases in the United States. SCI, in its best outcome, may partially and temporarily disconnect the spinal cord from the brain. Some neuronal pathways remain intact in most S CI individuals, whose recovery depends on the utilization of the surviving connections. There is a change in the control of voluntary movements of the extremities by the cerebral cortex of the brain following spinal cord injury.

The technology of high-resolution EEG co-registered with MRI was applied to non-invasively …

Advances In Dna Affinity Chromatography, William Himanshu S. Gadgil

Theses and Dissertations (ETD)

Different aspects of DNA affinity chromatography such as DNA complexity heparin elution, the Bi-column method and the oligonucluotide trapping method were studied. The complexity (length) of a DNA sequence attached to an affinity chromatography column affects column retention, and the purity of transcription factors obtained. T18: A18 tailed DNA affinity columns were better suited for purification of most of the transcription factors than either the discrete or concatemeric DNA affinity columns. A novel method using heparin for eluting transcription factors from DNA Sepharose columns was characterized. The amount of the lac repressor chimera which eluted from the column was shown …
