Characterization Of Lipid-Anchored Inhibitor Rulers As A Measure Of Enzyme Topography In Coagulation Enzyme Factor Xa, Robin C. Conley Jul 2014

Characterization Of Lipid-Anchored Inhibitor Rulers As A Measure Of Enzyme Topography In Coagulation Enzyme Factor Xa, Robin C. Conley

PCOM Biomedical Studies Student Scholarship

The blood coagulation cascade is activated under various circumstances such as an injury. This system involves a tightly regulated series of events. The enzymes involved assemble with their respective cofactors on lipid membranes to reach their full procoagulant complex potential. The coagulation cascade is divided into intrinsic and extrinsic portions, both of which converge into a common pathway with the activation of factor X (FXa). FXa is a very important part of the blood coagulation cascade because its activation is primarily responsible for thrombin generation. Activation of FXa alone is, however, insufficient to produce a fully …


Effect Of Heme Oxygenase-1 On Matrix Metalloproteinase-3 Expression In Human Fibroblasts, Theresa A. Stangl Jan 2014

Effect Of Heme Oxygenase-1 On Matrix Metalloproteinase-3 Expression In Human Fibroblasts, Theresa A. Stangl

Heme oxygenase-1(HO-1) is an enzyme that plays a very important role in the resolution of inflammation. HO-1-based therapies are effective in a number of disease conditions. However, HO-1 also increases tumor growth, angiogenesis, metastasis and chemoresistance. Matrix metalloproteinase-3 (MMP-3) is an enzyme involved in physiological and pathophysiological tissue remodeling. Unbalanced expression of MMPs is a key feature of connective tissue destruction in chronic inflammatory conditions. Previously shown in this laboratory, the HO-1 inducer, hemin, increased MMP-3 mRNA expression in some HGF cultures. To assess whether HO-1 and/or its products regulate expression of MMP-3 in human fibroblasts, the effect of HO-1 …


An Analysis Of Abnormal Electrocardiograms In First And Second Year Medical School Students, Molly Anne Kalish Jan 2014

An Analysis Of Abnormal Electrocardiograms In First And Second Year Medical School Students, Molly Anne Kalish

PCOM Biomedical Studies Student Scholarship

The high stress level placed upon medical school students, particularly during their first and second didactic years, may have a negative effect on their health. Although surveys and subjective questionnaires have been used to evaluate the effects medical school has upon a student’s cardiovascular health, there has been little clinical data obtained to confirm this notion. The aim of this longitudinal study was to demonstrate whether any abnormal cardiovascular parameters, specifically QTc wave interval, cardiac axis vector and blood pressure abnormalities, could be documented to occur in two different classes of medical students during their first two years. Such information …
