Background and purpose: Ëmbryo co-culture systems with somatic cells have been a subject of extensive study as valuable tools to promote embryo in vitro development. The aim of this study was to evaluate, the Ëffects of a special kind of co-culture system in which somatic cells were cultured as polarized monolayer on mouse embryo development. Materials and methods : Human oviduct was obtai...
Purpose: To compare effects of polarized epithelial monolayer prepared from human oviduct and uterus on mouse one and two-cell embryo development. Materials and Methods: Human oviduct and endometrial tissue was obtained from patients who had undergone total hysterectomy. The epithelial cells were isolated from tissue and cultured on extracellular matrix (ECM) Gel coated Millipore filter insert...
introduction: the aim of this study was to investigate the growth and development of mouse two cell embryo on human uterine polarized monolayers. material and methodes: human endometrial tissue was obtained from patients who had undergone total hysterectomy. then, epithelial cells were isolated by collagenase i 0.25% and cultured on either ecm gel coated millipore filter insert (polarized) or p...
By publishing translation of my Dissertation I am carrying out promises I gave during years to many people around the world. As the interest for polarized positron production is growing at SLAC now, I decide to make quick translation. This is a translation, not a new publication so I have neither right to upgrade neither any subject to the latest developments [which are reflected in, say, CLNS ...
circularly-polarized antenna is built based on new siw(substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (rhcp) and fabricated in two separate layers. a broadband impedancebandwidth of 13.9% and a rhcp axia...
How the visual system detects surface reflectance - lightness - has puzzled researchers for centuries. A new study of contexts that capture the characteristic luminance range of natural scenes rules out a long-standing theory of lightness perception.
In order to protect their food from competitors, ball-rolling dung beetles detach a piece of dung from a pile, shape it into a ball, and roll it away along a straight path [1]. They appear to rely exclusively on celestial compass cues to maintain their bearing [2-8], but the mechanism that enables them to use these cues for orientation remains unknown. Here, we describe the orientation strategy...
Purpose: This study designed to examine polarized culture of epithelial cells from human ovidutc and their ultrastracture under polarizing condition. Materials and Methods: The human oviduct was obtained from patients having undergone total hysterectomy and epithelial cells were isolated using collagenase type I. The epithelial cells were either cultured on ECM (Extracellular matrix) Gel coate...
For neutrino scattering from polarized electron, the weak interaction term in the cross section is significantly suppressed by the polarized term. The magnetic moment term does not receive any correction from the electron polarization. Hence, the study of the magnetic moment of neutrinos through scattering from the polarized electron leads to a stronger bound on the neutrino magnetic moment com...
