Background. Long-term graft patency is the major factor impacting survival after coronary artery bypass grafting. Arteries are superior in this regard. Radial artery is considered the second best conduit after internal mammary artery. Several studies have shown excellent radial artery patency. We evaluated the morphologic characteristics of radial artery by(More)
the ssDNA-binding mouth of DnaG distal from DnaB, orienting the active site of primase inward, toward the center of the ring, where it is positioned to accept ssDNA as it is extruded from DnaB (Fig. 4, right). Alternatively , it is possible that mechanistic differences between 6:6 and 6 :1 helicase-primase systems lead to different relative orientations of(More)
