Bioactive and Biocompatible Coatings for Endotoxin Capture in Treatment of Sepsis

Creator:: Su, Jonathan
Abstract:: Sepsis is a blood infection caused by circulating pathogens and cell wall fragments that affects over 1 million patients per year in the United States. When bacterial cell membranes are lysed by antibiotics, cell wall fragments containing lipopolysaccharides (LPS) are released. As a result, the capture of LPS is critical...

Artistic Interpretation of the Significance of Human Breast Cancer Cell Vinculin Distribution in Different Extracellular Matrix Conditions

Creator:: Hsiao, Yu-Tin
Abstract:: There are clues that suggest human breast cancer cells use collagen fibers to migrate, and vinculin is a transmembrane protein associated with how cells attach to their environment. Therefore, immunostaining for the vinculin will shed some light in how human breast cancer cells are attaching to their environment. Immunostaining for...
