Osteogenic scaffolds reproducing the natural bone composition, structures, and properties have represented possible frontier of artificially orthopedic implants with great potential to revolutionize surgical strategies against bone-related diseases. However, it is difficult achieve an all-in-one formula simultaneous requirement favorable biocompatibility, flexible adhesion, high mechanical stre...

As sensor nodes communicate via wireless channels, information security is essential for networks. Efficient protection mechanisms to ensure data among are critical. This study developed the bi-directed grouping (top-down (TDG) and bottom-up (BUG)) methods. In this study, we propose a group-based key distribution method, “aggregator-based grouping” (ABG), which combines advantages of TDG BUG ad...

OBJECTIVES/HYPOTHESIS To evaluate the acoustic effect after canal wall-down tympanoplasty with sectioning of the tensor tympani muscle (TTM) tendon in patients with chronic otitis media. STUDY DESIGN Prospective, controlled clinical trial. METHODS From January 2010 to April 2014, 212 patients underwent canal wall-down tympanoplasty with ossicular chain reconstruction in one-stage surgery. F...

Introduction: Hearing assessment after tympanoplasty is done by taking pure tone average. This study was performed to compare the hearing results obtained from the averages of three and four speech frequencies namely 0.5, 1,2KHz and 0.5,1,2,4 KHz in type III tympanoplasty. Methods: This study was conducted in Tribhuwan university teaching hospital and Kathmandu university hospital, Dhulikhel fr...

Atheromatous plaques usually contain antigens of the periodontitis-causing bacteria Streptococcus mutans though molecular mechanism of this incorporation remains unknown. Since vascular adhesion and inflammatory potential of Immune Complexes (IC) are known we investigated the naturally occurring plasma antibodies that recognize major antigens from S. mutans. S. mutansbinding plasma proteins (SM...

Objective. Evaluate a porous polyethylene prosthesis with two-point stabilization in total ossiculoplasty. This approach utilizes a lateral as well as a medial graft to stabilize a total ossicular prosthesis (TOP). Study Design. Retrospective cohort review of total ossiculoplasty. Methods. All patients who underwent total ossiculoplasty during the years 2004-2007 were included in the study grou...

The study aims to identify the correlation between arterial and venous blood gas variables, in patients with metabolic acidosis secondary to renal failure and/or diabetic ketoacidosis(DKA). Paired arterial and venous blood samples of 100 patients, with metabolic acidosis resultant to renal failure and/or diabetic ketoacidosis during 2009-2011, were analyzed and the correlation between the varia...

Metabolic acidosis has been proved to be a risk factor for the progression of chronic kidney disease, but its relation to acute kidney injury (AKI) has not been investigated. In general, a diagnosis of metabolic acidosis is based on arterial blood gas (ABG) analysis, but the diagnostic role of carbon dioxide combining power (CO2CP) in the venous blood may also be valuable to non-respiratory pat...

INTRODUCTION The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best. MATERIALS AND METHODS A prospective study of 80 pa...

OBJECTIVES We aimed to investigate the impact of arterial blood gas (ABG) on morbidity and mortality in chronic obstructive pulmonary disease (COPD) patients undergoing CABG surgery. MATERIAL AND METHODS The records for 75 COPD patients who underwent elective CABG surgery our institution clinic between November 2008 to 2011 and had a forced expiratory volume in 1 second (FEV1)/forced vital ca...
