Evaluation of the Effect of Bosentan-Mediated Endothelin Receptor Blockade on Flap Survival in Rats: An Experimental Study [PDF]

, 2016
Local skin flaps are important tools for performing plastic surgery. Skin flaps are used for closure of defects after tumor excision or in tissue losses after trauma. However, problems associated with these flaps are commonly encountered, particularly in

Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

Advanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Comment to: Great saphenous vein surgery without high ligation of the saphenofemoral junction, by Casoni P, Lefebvre-Vilardebo M, Villa F, Corona P. J Vasc Surg 2013;58:173-8.

Veins and Lymphatics, 2014
Traditional surgical treatment of varicose disease requires an invasive procedure like high ligation of sapheno femoral junction (SFJ), resulting in high recurrence rates, especially in the long term. The aim of this prospective randomized study was to
