Polarized views
One can almost feel the strain as a newt lung epithelial cell (top left) undergoes mitosis. The white spindle fibers anchor the chromosomes (visible in outline) between the spindle poles, while kinetochore microtubule fibers connect each chromatid at its centromere to one of the mitotic poles. Elongated mitochondria, long stress fibers and small, spherical organelles can also be seen surroundin...
متن کاملPolarized Cells, Polarized Views: Asymmetric Cell Division in Hematopoietic Cells
It has long been recognized that alterations in cell shape and polarity play important roles in coordinating lymphocyte functions. In the last decade, a new aspect of lymphocyte polarity has attracted much attention, termed asymmetric cell division (ACD). ACD has previously been shown to dictate or influence many aspects of development in model organisms such as the worm and the fly, and to be ...
متن کاملMicrostructural Analysis of Human White Matter Architecture Using Polarized Light Imaging: Views from Neuroanatomy
To date, there are several methods for mapping connectivity, ranging from the macroscopic to molecular scales. However, it is difficult to integrate this multiply-scaled data into one concept. Polarized light imaging (PLI) is a method to quantify fiber orientation in gross histological brain sections based on the birefringent properties of the myelin sheaths. The method is capable of imaging fi...

European Journal of Information Systems (2006) 15, 239–240. doi:10.1057/palgrave.ejis.3000627 In the third issue of the 2005 volume of the European Journal of Information Systems, I introduced a new Editor’s View series to the journal, starting with mine (Paul, 2005). In this issue, I am pleased to present the second and third Editor’s View papers by the Editors of the Information Systems Journ...
متن کاملNovel Circularly Polarized Substrate Integrated Waveguide SLOT Antanna
Circularly-polarized antenna is built based on a 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 a...
