The results of the measurements show that the mean DNA content per nucleus in the intact rat liver is 6.5 pg, and that most nuclei are about equal in size to the diploid nucleus (42.5 μ 2 ). DNA synthesis began in the regenerating liver before 18 h after the operation. By 24 h the...
To specifically assess the nucleus size and its relationship to cell size for human bulbar conjunctival cells. Impression cytology samples were taken from the nasal side of the intra-palpebral zone of the bulbar conjunctival surface from 20 young adult white European males, half of whom were succes...
[A] : Nucleus controls metabolic as well as hereditary activities of the cell. [R] : Size of nucleus is related to the size of the chromosomes . View Solution Assertion if wavelength is of the order of distance between the slits, then figure size is large. Reason Fringe width is gi...

A two-phase segmentation of cell nuclei using fast level set-like algorithms. An accurate localization of a cell nucleus boundary isinevitable for any further quantitative analysis of varioussubnuclear structures within the cell nucleus. In this paper,we present a novel approach to the cell nucleus...
Physical plasticity of the nucleus in stem cell differentiation Cell differentiation in embryogenesis involves extensive changes in gene expression structural reorganization within the nucleus, including chromatin conde... J. David Paierowski,KN Dahl,FL Zhong,... - 《Proc Natl Acad Sci U S A》 被...
Size of the nucleus would also vary not only depending upon the type of cell involved but also according to activity of cell. The nucleus will be larger in an active cell, but will be smaller in a resting cell. Number, shape and size of nucleus ...
Nucleus sizePloidyIn order to better understand which are the factors involved in the control of nuclear size, and more precisely, to clarify why nuclear hypertrophy doesnt always follow genome increase, biological techniques combined with a strict mathematical approach have been applied to study the ...
Nuclear-uptake nanodrug delivery systems, which enable intranuclear release of anticancer drugs, are expected to address this challenge by bypassing P-gp. However, before entering the nucleus, the nanocarrier must pass through the cell membrane, necessitating coordination between intracellular and ...
The formation and maintenance of subcellular structures and organelles with a well-defined size is a key requirement for cell function, yet our understanding of the underlying size control mechanisms is limited. While budding yeast cell polarization and
