Three-dimensional interphase organization of metazoan genomes has been linked to cellular identity. However, the principles governing 3D interphase genome architecture and its faithful transmission through disruptive events of cell-cycle, like mitosis, are not fully understood. By using Brownian dynamics simulations of Drosophila chromosome 3R up to time-scales of minutes, we show that chromati...

Condensin complexes play vital roles in chromosome condensation during mitosis and meiosis. Condensin II uniquely localizes to chromatin throughout the cell cycle and, in addition to its mitotic duties, modulates chromosome organization and gene expression during interphase. Mitotic condensin activity is regulated by phosphorylation, but mechanisms that regulate condensin II during interphase a...

As a liquid-liquid system is far from equilibrium state, the phase thickness is variable when mass transfer process with chemical reaction occurs in interphase zone, and a dispersible transitional layer called the interphase dispersed zone IDZ is formed. The IZD model composed of thermodynamically instable O/W or W/O microemulsion has reasonably explained enormous experimental phenomena in nonl...

Despite the fundamental importance of diffusion for embryonic morphogen gradient formation in the early Drosophila melanogaster embryo, there remains controversy regarding both the extent and the rate of diffusion of well-characterized morphogens. Furthermore, the recent observation of diffusional "compartmentalization" has suggested that diffusion may in fact be nonideal and mediated by an as-...

When two immiscible polymers are brought into intimate contact, highly localized mixing of polymer chains creates an “interphase” region. We have fabricated materials that are entirely interphase by forced assembly of two immiscible polymers. Assemblies of thousands of alternating layers of two polymers, with individual layer thickness on the nanometer size scale of the interphase, were created...

abstract background: to produce a reliable probe suitable for aneuploidy detection of chromosome 13 on uncultured lymphocytes and amniocytes by fluorescence in situ hybridization (fish), we used a contig of three overlapping cosmids mapped to 13q12.3. methods: the cosmid dna carrying the expected sequences of human chromosome 13 was isolated from host cells and labelled with biotin-11-dutp. the...

Fluorescence in situ hybridization (FISH) probe for the identification of the Philadelphia (Ph) translocation [t(9;22) (q34;q11)] in chronic myelogenous leukemia cells was developed by inter-Alu-polymerase chain reaction of DNA from an interspecific somatic cell hybrid containing approximately 5 Mb of human DNA covering the ABL gene region on human chromosome 9q34. This probe was large enough t...

Isothermal kinetics of the exchange absorbed water in a silica hydrogel (SH) with ethanol was examined. The isothermal kinetic curves were measured at temperatures: T = 297, 306 and 316 K. rate analysed as function time. possibility mathematical description by Brouers Sotolongo-Costa?s (BS) fractal?s model Parameter values (n, ?, ?) their changes temperature calculated. By applying method Ozao,...

In this paper, interphases in unidirectional fiber-reinforced composites under transverse loading are modeled by an advanced boundary element method based on the elasticity theory. The interphases are regarded as elastic layers between the fiber and matrix, as opposed to the spring-like models in the boundary element method literature. Both cylinder and square unit cell models of the fiber-inte...
