4 A rare case of adult medullomyoblastoma with unique location presented. The patient was admitted to our clinic with the history of progressive balance disorder, nausea and vomiting. Disequilibrium had started 2 months earlier. The patient underwent a craniotomy and histopathologic examination revealed a biphasic tumor. Few definite strap cells with striation were identified in the tumor. The ...

Sarcomere length of a cardiomyocyte is an important control parameter for physiology studies on a single cell level; for instance, its accurate determination in real time is essential for performing single cardiomyocyte contraction experiments. The aim of this work is to develop an efficient and accurate method for estimating a mean sarcomere length of a contracting cardiomyocyte using microsco...

Microtubule-associated fibers from the basal apparatus of the green flagellate alga Spermatozopsis similis exhibit a complex cross-striation pattern with 28-nm periodicity and consist of 2-nm filaments arranged in several layers. Fibers enriched by mechanical disintegration and high salt extraction (2 M NaCl) of isolated basal apparatuses are soluble in 2 M urea. Dialysis of solubilized fibers ...

In quail oviduct, a 175K (K = 10(3) Mr) protein associated with striated rootlets was previously identified by Klotz and co-workers using monoclonal antibody CC310. As this monoclonal antibody recognizes several proteins on immunoblots of ciliated cells, we prepared a polyclonal antibody monospecific to the 175K protein by intrasplenic immunization of mice. Immunofluorescence study confirmed th...

The striation model describes the evolution of plasma clouds along and across the geomagnetic field B in the earth ionosphere. The plasma clouds drift across the ionosphere in the presence of an ambient electric field and a neutral wind. In this article we introduce new techniques to extend the simulation tools to the earth magnetic field geometry. The model morevor allows a three dimensional r...
