We have examined the biomechanical development of the notochord of Xenopus early tail-bud embryos by: (1) quantifying morphological and mechanical changes in the embryo during stages 20-28, and (2) conducting manipulative experiments to elucidate mechanical roles of various components of the notochord. The notochord, which is composed of a stack of flat cells surrounded by a connective tissue s...

OBJECTIVE To evaluate the usefulness of septal batten grafts to correct cartilaginous septal deformities in endonasal septoplasty. DESIGN Retrospective study. SETTING University medical center. PATIENTS Of 430 patients who underwent endonasal septoplasties from January 2006 to January 2011, 30 received septal batten grafts and were enrolled in the study. Twenty-eight patients were male an...

Locked intramedullary nailing is the current standard of treatment for femoral shaft fractures and has low complication rates. Bent femoral intramedullary nails resulting from secondary trauma are rare and technically challenging. This article describes a case of a 36-year-old man who presented with a bent femoral intramedullary nail following a motorcross accident. The patient had a previous f...

The morphology, distribution, and configuration of coiled perimysial fibers of rat heart papillary muscle were studied. Methods included bright-field light microscopy of silver-stained sections, scanning and transmission electron microscopy, and differential interference contrast light microscopy of unfixed and unstained specimens. Coiled fibers, elliptical in cross section, are arranged in a b...

Abstract: Purpose: There are many problems that occur in the pronunciation and delivery of information both writing orally visually. This happens because there is no filter language style, therefore style needed with aim every conveyed can be digested consumed properly by listeners according to age level listener Method: scientific work a descriptive study use qualitative approach. using survey...

Background: Septoplasty is a surgical procedure to straighten the bone and cartilage dividing space between your two nostrils (septum). If septoplasty performed alone or as part of rhinoplasty procedure, internal nasal splints are generally used.
 Objective: To compare silicone septal with integral airways silastic sheets after surgery in terms patient breathing (with splint place).

This paper explores the possibility of combining solid state accelerometers with a low resolution position sensor to provide clean estimates of automobile handwheel position, velocity and acceleration for use in force feedback. Typically determining the acceleration and velocity of the handwheel requires differentiating a position sensor such as an encoder or potentiometer. Unless expensive hig...

We applaud the extensive systematic review and metaanalysis by Zampieri and colleagues on inhaled antibiotics for ventilator-associated pneumonia (VAP) [1] but would like to add some comments regarding inhaled colistin for treatment of VAP caused by multidrugresistant Gram-negative bacteria (MDR-GNB). In patients with cystic fibrosis, the equivalent of 160 mg colistimethate sodium (CMS) produce...

and Applied Analysis 3 the unstable manifold in U0 by using the method introduced in Zhu 9 . According to the invariance and symmetry of these manifolds, we can deduce that system 2.1 has the following form inU0: ẋ x ( λ ( , μ ) O 1 ) , ẏ y −λ , μ O 1 , u̇ v ( ω ( , μ ) O 1 ) u ( O x O ( y ) O u ) O ( xy ) , v̇ u −ω , μ O 1 ) − vO x Oy O v ) −Oxy, 3.1 where λ 0, μ λ, ω 0, μ ω,O 1 O x O y O u O v ...
