INTRODUCTION Capsular contracture after augmentation mammoplasty occurs at a rate of 15% to 45%. The purpose of the present study was to determine the effect of implant core type (silicone versus saline) on the rate of capsular contracture in augmentation mammoplasty. METHODS A systematic review was conducted through a search of three electronic databases. Two reviewers independently scanned ...

Accurate mechanical property data obtained at large shear deformations and high frequencies are a fundamental component of realistic numerical simulations of soft tissue injury. Although many commercial systems exist for testing shear properties of viscoelastic materials with properties similar to soft biological tissue, none are capable of determining properties at high loading rates necessary...

Introduction: The MRI based measurement of dynamic 3D deformation of soft tissue in-vivo is relevant to many areas of research such as cardiac biomechanics, the assessment of tumor motion and preoperative planning. Furthermore, when combined with inverse analysis, it enables the non-invasive determination of the mechanical properties of human soft tissue [1]. The current study uses SPAtial Modu...

Abstract: There is an ongoing drive to transform rigid, glass-based flat-panel devices (e.g., displays, solar cells, organic LEDs) into flexible devices on plastic substrates in order to improve flexibility, reduce weight, and reduce cost. The high cost, brittleness and slow coating process (<0.01 m/s) of the standard transparent conducting material, indium tin oxide (ITO), is limiting realizat...

In our study of the aging phenomena in silica suspensions we immersed precipitated silica particles in methyl-terminated PDMS (silicone oil), mineral oil, and glycerol/water and measured their viscoelastic properties as a function of time. We found that the samples based on silicone oil, initially of a pasty consistence, became fluid-like after a period of about three weeks. Aqueous samples age...

background peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. use of silicone may improve outcomes of these repairs. in this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. methods this experimental study w...

primary and 406 (36%) were secondary in which the patient had one or more previous breast augmentation procedures. Silicone gel implants were utilized in 471 (65%) of the primary and 324 (80%) of the secondary procedures. Operative technique involved a circumvertical or inverted-T mastopexy in 77% (n= 871) and a bilateral mastopexy in 93% of patients. The overall reoperation rate was 14.9% (13....

  Despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. Present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. Fifty- four male Wistar rats were divided into three experimental groups (n = 1...
