Cytonemes extend their reach.
Cytonemes are specialized filopodia, first described in the Drosophila wing imaginal disc, that were proposed to mediate long distance signalling during development. A recent report from Barna and colleagues (Sanders et al, 2013) published in Nature shows that cytonemes in the chick limb bud carry SHH signalling proteins out to signal receiving cells, thus highlighting their evolutionarily cons...
متن کاملComplex Surface Invaginations in Frog Oocytes
INTRODUCTION architecture of frog oocytes that had not been anticipated from previous examinations of many single thin sections . The increased penetrating power of high voltage electron microscopes (2, 5) permits thick rather than thin slices of embedded biological tissues to be examined . This capability has created a means for effective examinations of three-dimensional intracellular structu...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولIncorporating Diffusion in Complex Geometries into Stochastic Chemical Kinetics Simulations
A method is developed for incorporating diffusion of chemicals in complex geometries into stochastic chemical kinetics simulations. Systems are modeled using the reaction-diffusion master equation, with jump rates for diffusive motion between mesh cells calculated from the discretization weights of an embedded boundary method. Since diffusive jumps between cells are treated as first order react...
متن کاملMeshing of domains with complex internal geometries
This paper presents a meshing algorithm for domains with internal boundaries. It is an extension of the gridding algorithm presented by Persson and Strang. The resulting triangulation matches all boundaries, and the triangles are all nearly equilateral. Equilateral triangles are beneficial for a finite volume discretization, as fluid flow between elements of very different size is only possible...
