In this study, the vibration behavior of functional graded (FG) circular and annular nanoplate embedded in a Visco-Pasternak foundation and coupled with temperature change is studied. The effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of FG circular and annular nanoplate. To obtain the vibration frequencies of the FG circular and annular nanopla...

In this article, an exact levy solution is presented for bending analysis of a functionally graded (FG) annular sector plate. The governing equilibrium equations are obtained based on the classical plate theory. Introducing an analytical method for the first time, the three coupled governing equilibrium equations are replaced by an independent equation in term of transverse deflection. This equ...

AIMS We evaluated the relationship between the mitral inflow velocities by pulsed Doppler echocardiography and mitral annular motion velocities by pulsed Doppler tissue imaging in patients with mitral annular calcification. METHODS AND RESULTS Fifty-three patients with mitral annular calcification were divided into two groups: severe mitral annular calcification (n=15, mitral annular calcific...

Anterior vertebral body tethering (VBT) in growing children has been reported as an alternative to fusion for thoracic idiopathic scoliosis. scoliosis correction (ASC) is our multi-year, multi-generational advancement upon VBT and a “de-tethering,” not tethering, procedure. ASC incorporates cords/screws similarly but technique that allows large derotation, curve correction, restoration of kypho...

INTRODUCTION Laparoscopic duodenal atresia repair is an advanced procedure performed in select pediatric surgical centers. Recently, sub-6mm endosurgical staplers have been introduced, facilitating and accelerating the creation of intracorporeal intestinal anastomoses. PRESENTATION OF CASE We performed a laparoscopic duodenojejunostomy in a one-day-old child with duodenal atresia due to annul...

REASON FOR PERFORMING STUDY Constriction of the digital flexor tendon sheath (DFTS) and its contents by the palmar/plantar annular ligament (PAL) is well recognised. However, primary injury of the PAL has not been well documented. OBJECTIVES To describe the clinical features of PAL injury, determine its prevalence with or without subcutaneous fibrosis and/or concurrent injury within the DFTS,...

The aim of this study was to evaluate the use of a single-portal endoscopic desmotomy of the PAL with the use of Arthrex - Centerline™. Ten horse distal front limbs from horses free of PAL disease were prepared for tenoscopy of the digital flexor tendon sheath (DFTS). A dual-port endoscopic desmotomy with a hook knife was performed in 5 specimens (Group A) and single port Arthrex-Centerline™ De...
