A patient underwent paclitaxel-eluting implantation for a saphenous vein graft stenosis. A follow-up angiogram at 8 months demonstrated no restenosis, with multifocal peristent contrast staining. After 10 years, a saphenous vein graft aneurysm was revealed within the stented segment. This late complication should be kept in mind when evaluating patients who have received prior drug-eluting stents.

BACKGROUND: Graft-derived cell-free DNA (GcfDNA), which is released into the blood stream by necrotic and apoptotic cells, is a promising noninvasive organ integrity biomarker. In liver transplantation (LTx), neither conventional liver function tests (LTFs) nor immunosuppressive drug monitoring are very effective for rejection monitoring. We therefore hypothesized that the quantitative measurement of donor-derived cell-free DNA (cfDNA) would have independent value for the assessment of graft integrity, including damage from acute rejection...

The development of advanced anode materials is of significance for the next generation of lithium ion batteries (LIBs). Herein, the imidazolium-based ionic liquids (ILs) was covalently grafted on the surface of graphene oxides (GO) via the carboxyl-amino bond,providing a loading hotbed for the Dawson-type POM of (NH4)6P2Mo18O62 (denoted as P2Mo18). The as-prepared GO-IL-P2Mo18 nanocomposite was characterized by FT-IR, Raman, TGA, SEM, TEM and XPS. When the nanocomposite was used as the anode material for lithium ion batteries (LIBs), it showed a high reversible capacity of 903...

We analyze, theoretically and by means of molecular dynamics (MD) simulations, the generation of mechanical force by a polyelectrolyte (PE) chain grafted to a plane and exposed to an external electric field; the free end of the chain is linked to a deformable target body. Varying the field, one can alter the length of the non-adsorbed (bulk) part of the chain and hence the deformation of the target body and the arising force. We focus on the impact of added salt on the magnitude of the generated force, which is especially important for applications...

ABO incompatibility is commonly observed in stem cell transplantation and its impact in this setting has been extensively investigated. HLA-mismatched unrelated donors (MMURD) are often used as an alternative stem cell source but are associated with increased transplant related complications. Whether ABO incompatibility affects outcome in MMURD transplantation for acute myeloid leukemia (AML) patients is unknown. We evaluated 1013 AML patients who underwent MMURD transplantation between 2005 and 2014. Engraftment rates were comparable between ABO matched and mismatched patients, as were relapse incidence [34%; 95% confidence interval (CI), 28-39; for ABO matched vs...

Tympanoplasty was conventionally performed using a microscope for decades. However, since the endoscope began to be used in middle ear surgery in the 1970s, endoscopic tympanoplasty has gained increasing attention. The main objective of this study was to compare endoscopic and microscopic tympanoplasty with and without ossiculoplasty, demonstrating the potential advantages, disadvantages, and outcomes of each. This retrospective study included 126 patients with chronic otitis media who received tympanoplasty from 2013 to 2015 in our hospital...

The grafting of fat mixed with adipose-derived stem cells (ASCs) is being increasingly applied to compensate for the disadvantages of previous fat grafting methods. Devices that automatically isolate fat stem cells also have recently been developed. ASCs were isolated from the inguinal region of White rabbits using Icellator(®), and the number of cells and their viability were measured. The cell count per fat graft (mL) was adjusted to the following concentrations and subcutaneously transplanted into the back: Control group, Fat + PBS; Fat + ASCs (×0...
