To provide a morphometric basis for any mathematical modeling of the coronary vasculature, data on the network of coronary capillary blood vessels and the topology of the arteriolar supply and venular drainage relative to the capillaries are presented. The diameters, lengths, and branching patterns of the coronary capillary blood vessels in the right and left ventricles of four pigs were measur...

Aptamers are oligonucleotides that are isolated and amplified on the basis of their recognition of a target molecule. In this study, an RNA aptamer isolated and amplified on the basis of its affinity for flavin mononucleotide (FMN) was covalently bound to the inner walls of fused-silica capillaries. This aptamer recognizes the flavin moiety of both FMN and flavin adenine dinucleotide (FAD). Whe...
