BACKGROUND During the mating pheromone response in budding yeast, activation of a mitogen-activated protein kinase (MAP kinase) cascade results in well-characterized changes in cytoskeletal organization and gene expression. Spatial reorganization of genes within the nucleus has been documented during cell-type differentiation in mammalian cells, but no information was previously available on th...

finger prints of 68 patients with down's syndrome and 93 controls have been collected and analyzed for topological of formulation of finger tip patterns suggested by loesch (1975). the results showed that there may be great differences in the dictionary of the finger patterns of the patients and their controls. mean lunar and radial patterns showed mostly significant differences among the patie...

Reorganization of centrosomal microtubule-organizing centres and the minus ends of microtubules occurs as the centrosomal ends of large microtubule bundles are repositioned and anchored to cell junctions in certain epithelial cells called inner pillar cells in the mouse organ of Corti. The microtubule bundle that assembles in each cell consists of two distinct microtubule arrays that run closel...

background: although, different grafts are used for nasal tip plasty in cases with under projected or ill defined tip, the selection of a graft material, which provides sufficient amount of tissue with least donor site morbidity and low recipient site complication is challenging. the objectives of the present study were to examine the usefulness of cartilaginous dorsum as a proper material for ...

Characteristics of rotor blade tip clearance flow in axial compressors can significantly affect their performance and stable operation. It may also increase blade vibrations and cause detrimental noises. Therefore, this paper is contributed to investigate tip leakage flow in a low speed isolated axial compressor rotor blades row. Simulations are carried out on near-stall condition, which is val...

This article explores the use of unauthorised projection-based artworks and messages as a form activism, contextual street art. The issues authority permission that are central to political nature art unique in case projection ephemeral temporary light-based installations skirt some fundamental objections most graffiti such damage physical surfaces. Through changes imposed on urban forms by lig...

background: providing a cross-sectional image is essential for preimplant assessments. computed tomography (ct) and cone beam ct (cbct) images are very expensive and provide high radiation dose. tangential projection is a very simple, available, and low-dose technique that can be used in the anterior portion of mandible. the purpose of this study was to evaluate the accuracy of tangential proje...

in this paper, we introduce a new concept of volumes difference function of the projection and intersection bodies. following this, we establish the minkowski and brunn-minkowski inequalities for volumes difference function of the projection and intersection bodies.
