Photopolymerized crosslinked networks of poly(ethylene glycol; PEG) diacrylate (MW 8000) were derivitized throughout their bulk with Arg-Gly-Asp (RGD)-containing peptide sequences. Incorporation was achieved by functionalizing the amine terminus of the peptide with an acrylate moiety, thereby enabling the adhesion peptide to copolymerize rapidly with the(More)
To determine the myocardial response to prolonged pressure-loading and unloading, kittens weighing 0.8-1.2 kg underwent pulmonary artery banding, which initially elevated right ventricular (RV) systolic pressure by 10-15 mm Hg. 52 and 76 wk later; RV weight/body weight had increased by approximately 80%. Total RV hydroxyproline had increased significantly,(More)
Passive stiffness and hydroxyproline content of myocardium hypertrophied by pressure-loading were determined in kittens 2, 8-16, and 24-52 wk after pulmonary artery banding, which initially elevated right ventricular systolic pressure by 10-15 mm Hg. Right ventricular mass increased by approximately 75%, three-quarters of which occurred during the first 2(More)
