The Density of State and the Natural Bond Orbital calculations were carried out to study theoxidation of CO on Au14 nano cluster through two different mechanisms and determining the bestmechanism for the reaction. Chemisorption of O2 and CO on the nano cluster led to change in energy,density of state and its thermodynamic properties. We calculated the energy band gap between thehighest occupied...

Penile prosthesis is a functional option for patients who have erectile dysfunction after failed medical and intracavernosal treatments. Malleable penile prosthesis is a good alternative. Penile prosthesis implantation is a surgical process. Seldomly complications occur. In this study we presented a 61 y old man who has malfunctioned and broken penile prosthesis due to cross implantation.

In the surgical treatment of otosclerosis, the coupling between the stapes prosthesis and the long process of the incus is critical. After surgery, connective tissue and mucosa may grow over the coupling area and thereby influence the sound transmission properties of the incus-prosthesis interface. It was the hypothesis of this study that tissue ongrowth in the incus-prosthesis interface has li...

BACKGROUND This study investigated the patient's self-report and clinician's confirmation of tracheoesophageal voice prosthesis leakage patterns (through or around) with or without the cough reflex and whether prosthesis diameter affected the leakage route. METHODS Sixty-six consecutive participants with a total of 200 patient-initiated reasons for prosthesis changes were enrolled prospective...

BACKGROUND With the increasing use of hydroxyapatite orbital implants, the complication of exposure has become apparent to oculoplastic surgeons. Many kinds of patch grafts, such as sclera, dermis, and hard palate mucosa, have been used to cover exposed hydroxyapatite implants with inconsistent results. In this study, the authors use a newly developed technique, autogenous retroauricular myoper...

BACKGROUND Use of the proximal part of the femur in total hip arthroplasty enables preservation of the distal femur for later revisions. To use this advantage, different types of short-stem prosthesis have been developed in recent years. Although cementless hip arthroplasty is not common in the treatment of canine osteoarthritis, the use of cementless short-stems might be an alternative therapy...

BACKGROUND: Ocular prosthetics remains an important and actual task in the rehabilitation of patients with anophthalmos various origins.
 AIM: To increase effectiveness cosmetic at formation a primary and/or delayed supporting stump simultaneous reconstructive procedures on orbital bone structures.
 MATERIALS AND METHODS: A retrospective analysis subatrophy deformities walls was carri...

In vitro biomechanical analysis after cervical disc replacement (CDR) with a novel artificial disc prosthesis (mobile core) was conducted and compared with the intact model, simulated fusion, and CDR with a fixed-core prosthesis. The purpose of this experimental study was to analyze the biomechanical changes after CDR with a novel prosthesis and the differences between fixed- and mobile-core pr...

OBJECTIVES Secondary tracheoesophageal (TE) puncture standardly involves placement of a catheter at time of TE fistula creation. We explore the feasibility of placement of the prosthesis at the time of TE puncture (TEP) obviating the need for a subsequent procedure to place the prosthesis. We describe the technique and evaluate the success and potential advantages. STUDY DESIGN Retrospective ...
