Stroke in humans is usually focal and occurs in the Middle Cerebral Artery (MCA) distribution. There are several rat models that mimic strokes clinically seen in human. Severity of ischemia can be determined by occlusion time, arteries occluded i.e. MCA alone or combined with one or both Common Carotid Arteries (CCA), and/or location of the occlusion. In(More)
The adsorption of atomic oxygen and hydroxide on a platinum electrode in 0.1 M HClO4 or H2SO4 electrolytes was studied in situ with Pt L(2,3) X-ray absorption spectroscopy (EXAFS and XANES). The Pt L3 edge absorption data, mu, were collected at room temperature in transmission mode on beamline X-11A at the National Synchrotron Light Source using a custom(More)
Chemically defined surfaces were created using self-assembled monolayers (SAMs) of hydrophobic and hydrophilic silanes as models for implant coatings, and the morphology and physiology of cardiac myocytes plated on these surfaces were studied in vitro. We focused on changes in intracellular Ca(2+) because of its essential role in regulating heart cell(More)
X-ray absorption spectroscopy (XAS) is utilized in situ to gain new insights into the electronic and chemical interactions of anions specifically adsorbed on Pt/C. A novel difference methodology was utilized, along with full-multiple scattering calculations using the FEFF8 code, to interpret the X-ray absorption near edge structure (XANES). Significant(More)
Impaired wound healing is a significant source of morbidity in humans. As in humans, the homozygous diabetic (C57BL/ KsJ db/db) mouse exhibits impaired wound healing. These animals develop resistant hyperglycemia, obesity, polyuria and polyphagia, as a result of a single autosomal recessive mutation on chromosome 4 [1]. Injury to the skin initiates a(More)
