The extracellular matrix (ECM) of the heart is composed largely of elastin and collagen and plays many roles in cardiac wall and valve homeostasis. Maintenance of a healthy cardiac system relies on controlled biosynthesis, maturation, function, and breakdown of ECM proteins. Dysregulation of proteolytic enzymes may disrupt these normal biological processes in myocardium-coronary-valve disease (...

Formation process of single-walled carbon nanotubes by the catalytic chemical vapor deposition method is studied by molecular dynamics simulation. We start the calculation with randomly distributed carbon-source molecules and a nickel cluster to investigate the metal-catalyzed growth of a cap-structure of a nanotube. When the catalytic cluster reaches saturation with carbon atoms, hexagonal net...

The cytotoxicity of different samples of carbon nanotubes synthesised by catalytic chemical vapour deposition was investigated towards human umbilical vein endothelial cells, using two cytotoxicity standard assays (neutral red assay for the cell viability and MTT assay— tetrazolinium salt—for the cell metabolic activity). No cytotoxicity was found for any sample.

The unique physical and chemical properties of composite materials based on carbon nanofibers (CNFs) makes them attractive to scientists manufacturers. One promising method produce CNFs is catalytic vapor deposition (CCVD). In the present work, a erosion (CE) bulk microdispersed Ni-Cu alloys has been proposed prepare efficient catalysts for synthesis CNF-based composites. initial were obtained ...
