At 5 years postoperatively, DSO with a scraping technique and without Rho-kinase inhibitors resulted in sustained clinical amelioration of 3 of 5 patients (60%) with mild FED.

Here, we characterize two S-glycosyltransferases SunS and ThuS that selectively glycosylate one of five Cys residues in their substrate peptides; substitution of this Cys with Ser results in a strong decrease in glycosylation activity. Crystal structures of SunS and ThuS in complex with UDP-glucose or a derivative reveal an unusual architecture in which a glycosyltransferase type A (GTA) fold is decorated with additional domains to support homodimerization. Dimer formation creates an extended cavity for the substrate peptide, drawing functional analogy with O-glycosyltransferases involved in cell wall biosynthesis. This extended cavity contains a sharp bend that may explain the site selectivity of the glycosylation because the target Cys is in a Gly-rich stretch that can accommodate the bend. These studies establish a molecular framework for understanding the unusual S-glycosyltransferases.We report the case of a 25-year-old female who developed severe aortic regurgitation because of pulmonary autograft root dilatation late after Ross-Konno procedure. The geometric heights of all three cusps were relatively small, allowing for the David operation with a 24-mm straight graft. We carefully dissected the aortic root and, the dissection process was relatively straightforward,
