*Corresponding Author Kemei Peng [email protected] The Ostrich tibia belongs to the long bone, which has a complex structure comprising to different types of bone cell, a calcified extracellular matrix and two crisscross pipelines. Few present report concerning on the histological structure of Ostrich tibia had been carried out. This experiment was carried out to investigate the Tibia Morpholo...

Grain refinement can make conventional metals several times stronger, but this comes at dramatic loss of ductility. Here we report a heterogeneous lamella structure in Ti produced by asymmetric rolling and partial recrystallization that can produce an unprecedented property combination: as strong as ultrafine-grained metal and at the same time as ductile as conventional coarse-grained metal. It...

Slavoj Žižek has made it his essential project to renew an understanding of G.W.F. Hegel’s subjectivity by means of the psychoanalytic theory and practice of Jacques Lacan. One crucial element in such an endeavor is Lacan’s notion of the lamella, a particular understanding of excessive desire as indestructible and exterior to the self. I would like to investigate Žižek’s characterization of the...

BACKGROUND Tarsoconjunctival flap advancement, or the Hughes procedure, is among the techniques of choice for reconstructing full-thickness lower eyelid defects so as to restore normal anatomy and function with the best possible cosmetic outcome. The purpose of this study is to report the outcome of a series of patients treated with a modified Hughes procedure following malignant tumor removal....

purpose: to evaluate endothelial cell density (ecd) and morphology of clear corneal grafts after descemet stripping automated endothelial keratoplasty (dsaek) and to determine the factors that influence graft ecd postoperatively. methods: seventy-seven eyes (38 right eyes) of 64 patients (34 female subjects) who underwent dsaek for fuchs’ endothelial dystrophy (n=38) or pseudophakic bullous ker...

whit the extension of nanotechnology and materials engeneering, various nanoparticles are produced that have new characteristics but the toxic effects of them is still unknown in most of materials. nowadays metal oxide nanoparticales are widely used in indusery and other fields. this study was conducted goldfish with the average weigh of 3±0.5 gr and owerag length of 7±0.5 cm nd four cares of z...

The active forward movement of cells is often associated with the rearward transport of particles over the surfaces of their lamellae. Unlike the rest of the lamella, we found that the leading edge (within 0.5 microns of the cell boundary) is specialized for rearward transport of membrane-bound particles, such as Con A-coated latex microspheres. Using a single-beam optical gradient trap (optica...

Uniaxial tensile and relaxation tests were carried out on annulus fibrosus samples carved out in the circumferential direction. Images were shot perpendicularly to the loading direction. Digital image correlation techniques accurately measured the evolution of full displacement fields in both transverse directions: plane of fibres and plane of lamellae. In the fibre plane, strains were governed...

Polarity of the microtubule (MT) cytoskeleton is essential for many cell functions. Cytoplasmic linker-associated proteins (CLASPs) are MT-associated proteins thought to organize intracellular MTs and display a unique spatiotemporal regulation. In migrating epithelial cells, CLASPs track MT plus ends in the cell body but bind along MTs in the lamella. In this study, we demonstrate that glycogen...
