The Role of Syndecan-1 in Arterial Mechanotransduction

Creator:: Steyer, Benjamin G.
Abstract:: Hemodynamic forces regulate vascular homeostasis and arterial structure through mechanical stimuli by a process called mechanotransduction. Cellular response to mechanical forces involves coordination between cell surface receptors and intracellular signaling pathways. While previous work has focused on the role of integrin receptors in mechanotransduction, little is known about the role...

Surfactant Effects on Adsorption of Recombinant Factor VIII (rFVIII) at the Air-Water Interface

Creator:: Gray, Warren D.
Abstract:: The primary goal was to characterize the adsorption of a recombinant therapeutic protein in the presence of selected surfactant species at the air-water interface. For this purpose, dynamic interfacial tensiometry was used to determine the surface tension kinetics exhibited by protein solutions containing either Tween 80 or the poly[ethylene oxide]-...

Nisin adsorption to PEO-PPO-PEO tri-block copolymer layers and its resistance to elution by fibrinogen

Creator:: Ryder, Matthew P.
Abstract:: While hydrophobic surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] (PEO-PPO-PEO) surfactant Pluronic® F108 are highly resistant to plasma protein adsorption, the antimicrobial peptide nisin has been observed to adsorb in multilayer quantities at such surfaces, and the PEO chains themselves suggested to inhibit nisin exchange by blood proteins. But...

Nisin adsorption and function at hydrophobic surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] triblock surfactant Pluronic® F108

Creator:: Tai, Yuan-Ching
Abstract:: The adsorption and elution of the antimicrobial peptide nisin at hydrophobic, silanized silica surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]- poly[ethylene oxide] surfactant Pluronic® F108 was measured in situ, with ellipsometry. While such layers are known to inhibit protein adsorption, nisin was observed to adsorb in multilayer quantities, to an...

Retention of protein repulsive character and antimicrobial activity of PEO brush layers following nisin entrapment

Creator:: Auxier, Julie A.
Abstract:: Nisin, an amphiphilic, antimicrobial peptide, has been shown to integrate into the hydrophobic inner region of poly(ethylene oxide) (PEO) brush layers; however, the presence of integrated nisin may compromise the protein repulsive character of the PEO layer. In particular, the introduction of fibrinogen to nisin-loaded brush layers has been observed...

Fibrinogen adsorption at heparinized silica interfaces : history dependence and adsorption time effects

Creator:: Lee, Hyo Jin
Abstract:: Heparin was modified with adipic diliydrazide and covalently linked to surface-activated silica. Contact angle measurements were made to determine changes in surface at various stages of the derivatization. Xray photoelectron spectroscopy was used to analyze the elemental composition of the surface at each step of immobilizing heparin as well and...

Molecular origins of peptide entrapment in polyethylene oxide layers

Creator:: Wu, Xiangming
Abstract:: A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...

Synthesis and function of bioactive, block copolymer surfactant constructs as relevant to the preparation of anticoagulant and antibacterial medical implant surfaces.

Creator:: Joshi, Pranav R.
Abstract:: Nisin, an antibacterial peptide proven to be an effective inhibitor of Gram-positive bacteria, was incorporated into novel block copolymer constructs and tested for retained antibacterial activity. Covalent coupling was achieved by chemical modification of the N-terminal isoleucine to introduce a thiol group. Thiolated nisin derivatives were then linked to poly[ethylene...
