The ability to induce somatic cells to pluripotency by ectopic expression of defined transcription factors (e.g. KLF-4, OCT4, SOX2, c-MYC, or KOSM) has transformed the future of regenerative medicine. Here we report somatic cell reprogramming of human umbilical vein endothelial cells (HUVECs), yielding induced pluripotent stem (iPS) cells with the fastest kinetics, and one of the highest reprog...
PURPOSE To compare long-term patency of Heparin-Bonded Dacron (HBD) and Human Umbilical Vein (HUV) vascular prostheses in above-knee femoro-popliteal bypass surgery. DESIGN A prospective randomized multi-centre clinical trial. PATIENTS AND METHODS Femoro-popliteal bypasses were performed in 129 patients between 1996 and 2001. After randomization 70 patients received an HUV and 59 an HBD pro...
Compared to current treatments including surgery, radiation therapy, and chemotherapy, PDT offers the advantage of an effective and selective method of destroying diseased tissues without damaging surrounding healthy tissues. One of the aspects of antitumour effectiveness of PDT is related to the distribution of photosensitizing drugs. The localization of photosensitizers in cytoplasmic organel...
In machine learning, a popular tool to analyze the structure of graphs is the hitting time and the commute distance (resistance distance). For two vertices u and v, the hitting time Huv is the expected time it takes a random walk to travel from u to v. The commute distance is its symmetrized version Cuv = Huv +Hvu. In our paper we study the behavior of hitting times and commute distances when t...
In the development of engineered vascular grafts, assessing the material's interactive properties with peripheral blood cells and its capacity to endothelialize are important for predicting in vivo graft behavior. Current in vitro techniques used for characterizing cell adhesion at the surface of engineered scaffolds under flow only facilitate a terminal quantification of cell/surface interacti...
The use of ex vivo-derived scaffolds as vascular conduits has shown to be a clinically valid approach to repair or bypass occluded vessels. Implantation of allogeneic tissue grafts requires careful processing to lower immunogenicity and prevent bacterial infection. However, the mechanical/chemical treatments used to prepare biological scaffolds can result in significant alterations to the nativ...
ERG (Ets-related gene) is an ETS transcription factor that has recently been shown to regulate a number of endothelial cell (EC)-restricted genes including VE-cadherin, von Willebrand factor, endoglin, and intercellular adhesion molecule-2. Our preliminary data demonstrate that unlike other ETS factors, ERG exhibits a highly EC-restricted pattern of expression in cultured primary cells and seve...
Systemic urticaria in a 64-year-old woman was diagnosed as leukocytoclastic vasculitis by a punch biopsy of the skin. Her physical findings improved after prescription of prednisolone at a dose of 20 mg/day, but the skin rash relapsed with renal dysfunction, proteinuria, and hematuria when the dose of prednisolone was reduced over a period of 9 months to 1 mg/day. She was admitted to our instit...
