Polarized Radicals
نویسندگان
چکیده
Establishing polarized surfaces enables cells to carry out specialized tasks. In this issue, Lee et al. present a mechanism for cell polarization in which localized peroxidases are used to position the Casparian strip, a diffusion barrier deposited between endodermal cells in plant roots.

Defect-induced magnetism: Codoping and a prescription for enhanced magnetism
Recent works have given indication that the defect-induced magnetism in diluted magnetic semiconductors (DMSs), transition metal oxides (TMOs), and related materials is facilitated and enhanced by codoping and the synergistic action among the codopants. In the present work we demonstrate that the proposed defect-induced ferromagnetic coupling (FMC) exhibits the following features: bipartition, ...
متن کاملEffect of Two Polarized Culture System Prepared From Human Female Genital Tract on Mouse Embryo Development
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...
متن کاملSOMO–HOMO Level Inversion in Biologically Important Radicals
Conventionally, the singly occupied molecular orbital (SOMO) of a radical species is considered to be the highest occupied molecular orbital (HOMO), but this is not the case always. In this study, we considered a number of radicals from smallest diatomic anion radicals such as superoxide anion radical to one-electron oxidized DNA related base radicals that show the SOMO is energetically lower t...

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...
متن کاملPolarized and Non-Poarized Human Oviduct Epithelial Cell Ultrastructure in Vitro
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...
