We present the case of successful repair of an exposed glaucoma drainage tube by cornea graft fixation with tissue adhesive, and without subsequent coverage by adjacent conjunctiva or donor tissues. Patient with history of keratoglobus with thin cornea and sclera, and phthisical contralateral eye, underwent three unsuccessful corneal grafts followed by Boston type 1 keratoprosthesis in the righ...

BACKGROUND Left ventricular free wall rupture (LVFWR) is a dramatic complication after myocardial infarction. We present our mid-term clinical and echocardiographic results of LVFWR with an epicardial patch without cardiopulmonary bypass. METHODS From February 1993 to May 2001, 17 patients underwent surgery for LVFWR. The mean age+/-SD of 12 males and 5 females was 68+/-10 years. All patients...

BACKGROUND Since Wilcox's description of the simplified single-patch technique for atrioventricular septal defect (AVSD) repair in 1997, several studies have compared that technique with the two-patch technique. OBJECTIVE To report the mid- and long-term results of the simplified single-patch technique for complete AVSD repair. METHODS Retrospective study of 16 consecutive cases between Jan...

We investigated the tribological interaction between polytetrafluoroethylene (PTFE) and silicon oxide surfaces. A simple rig was designed to bring about a friction between the surfaces via sliding a piece of PTFE on a thermally oxidized silicon wafer specimen. A very mild inclination (~0.5°) along the sliding motion was also employed in order to monitor the tribological interaction in a gradual...

−Hydrophobic polydimethylsiloxane polytetrafluoroethylene (PDMS-PTFE) flat-sheet membranes for pervaporation (PV) of chloroform from aqueous solution were successfully fabricated by solution casting method. The structures and the performance of the membranes was characterized by X-ray diffraction (XRD), scanning electron microscope combined with energy dispersive X-ray spectroscopy (SEM-EDXS), ...

The high retear rates after surgery for irreparable rotator cuff tears can be explained by the healing capacity potential of tendons and the native rotator cuff enthesis characterised by complex morphological structures, called direct insertion. Many experimental researches have focused on biologically augmenting the rotator cuff reconstruction and improving tendon-bone healing of the rotator c...

Platinum (Pt) with foreign components has been considered as an effective approach to overcome CO poisoning, enhance the activity and decrease the usage of expensive Pt in fuel cells. In particular, PtFe is one of the superior binary Pt-based nanomaterial electrocatalysts for formic acid oxidation, which exhibits high resistance to CO poisoning and is a potential candidate for CO-tolerant alloy...
