Immunomodulatory Effects Of Novel Therapies For Stroke, Aaron A. Hall

USF Tampa Graduate Theses and Dissertations

Each year, approximately 795,000 people suffer a new or recurrent stroke. About 610,000 of these are first attacks, and 185,000 are recurrent attacks (Carandang et al. 2006). Currently the only FDA approved treatment for ischemic stroke is recombinant tissue plasminogen activator (Alteplase) (Marler and Goldstein 2003). Unfortunately its use is restricted to a short, 4.5 hour, time window. Two promising therapies in the treatment of stroke at delayed timepoints are human umbilical cord blood cells (HUCBC) and the sigma receptor agonist DTG

The first series of experiments were conducted to characterize the effects of sigma receptors on various aspects of …

The Role Of Extracellular Matrix And Matrix-Degrading Proteases In Neonatal Hypoxic-Ischemic Injury, Christopher C. Leonardo

USF Tampa Graduate Theses and Dissertations

Improvements in medical care over recent decades have increased the number of premature and low birth weight infants that survive hypoxic-ischemic (H-I) insults. Because there is a rising incidence in diseases associated with these events, it is critical to develop effective therapies to treat the various resulting neuropathies. Extracellular matrix constitutes the majority of brain parenchyma. Lecticans and matrix-degrading proteases including ADAMTSs (a disintegrin and metalloproteinase with thrombospondin repeats) and matrix metalloproteinases (MMPs) exert effects on cell viability and may be associated with either protective or destructive processes after H-I. Both ADAMTSs (Cross et al. 2006; Tian et al. 2007) …
