Cooperation between cadherins and the actin cytoskeleton controls many aspects of epithelial biogenesis. We report here that myosin VI critically regulates the morphogenesis of epithelial cell-cell contacts. As epithelial monolayers mature in culture, discontinuous cell-cell contacts are initially replaced by continuous (cohesive) contacts. Myosin VI is recruited to cell contacts as they become...

OBJECTIVE To study the incidence and distribution of adherent Gardnerella vaginalis. METHODS Bacteria adherent to desquamated epithelial cells in the urine were detected using fluorescence in situ hybridization (FISH). Urine from patients with bacterial vaginosis (BV, n = 20), their partners (n = 10) and different control populations (n = 344) including pregnant women and their partners, rand...

This study examines the correct and incorrect use of local cohesive ties cohesion errors in written narratives eleven- to twelve-year-old Spanish learners English as a Foreign Language (EFL) at different proficiency levels. The was carried out with pairs who collaboratively wrote narrative text response picture prompt. young learners’ texts were examined identify their four categories: lexical,...

that varies with distance, r, from the crack tip as r 1 2 . In this paper, a traction free plane stress wedge with a discrete cohesive zone along the intended crack-path is studied. Of interest is the in uence of the cohesive zone on the crack tip stress eld. Further, the in uence of the cohesive zone on the strain energy release rate is also investigated. Two example problems are studied; a do...

A one-dimensional vertical two-phase flow model for sedimentation-consolidation process is presented. The model is based on solving the continuity and momentum equations for both fluid and solid phases. In the non-cohesive case, the momentum transfer between the two phases is reduced to the drag force around a single particle modified to take the hindrance effects into account. In the cohesive ...

The fracture behaviour of human cortical bone was analysed considering a miniaturized version of the Double Cantilever Beam (DCB) test. A specific data reduction scheme based on crack equivalent concept was used to obtain the resistance curves. The definition of the cohesive laws mimicking the fracture process was performed measuring the crack tip opening displacement by digital image correlati...
