Microtubule depolymerization dynamics in the spindle are regulated by kinesin-13, a nonprocessive kinesin motor protein that depolymerizes microtubules at the plus and minus ends. Here we show that a single kinesin-13 homolog regulates flagellar length dynamics, as well as other interphase and mitotic dynamics in Giardia intestinalis, a widespread parasitic diplomonad protist. Both green fluore...

Microstructural study of the C49-TiSi, to C54-TiSi, polymorphic transformation has been performed to elucidate microstructural evolution and possible mechanism of the phase transformation. It has been shown that the nucleation of the C54-TiSi, is heterogeneous, and preferentially takes place at triple grain junctions or grain boundaries. The interphase interfaces between C49 and C54 disilicides...

The ability of the Schizosacchromyces pombe spindle pole body to nucleate microtubules is activated at the onset of mitosis for forming a mitotic spindle, but it is inactivated during interphase. We have previously developed an in vitro assay for studying the molecular mechanism of spindle pole body activation using permeabilized interphase S. pombe cells and Xenopus mitotic extracts. We have s...

The behavior of microphase-separated block copolymers has major contributions from the mixed interphase existing between the two homogeneous phases. However, relatively little has been known about the interphase itself and, in particular, its composition profile has never been measured directly. Here, we have used quantitative transmission electron microscopy to acquire the shape of the volume-...

Fibre reinforced polymer (FRP) composites are the most promising and elegant material of the present century. Their durability and integrity in various service environments can be altered by the response of its constituent i.e. fibre, polymer matrix, and the existing interface/interphase between the fibre and polymer matrix, in that particular environment. The interphase is generally manifested...

During the cell cycle, the organization of the cytoskeletal network undergoes dramatic changes. In order to reveal possible changes of the viscoelastic properties in the intracellular space during the cell cycle we investigated the diffusion of endogenous lipid granules within the fission yeast Schizosaccharomyces Pombe using optical tweezers. The cell cycle was divided into interphase and mito...

In the fission yeast Schizosaccharomyces pombe, cortical protein structures called interphase nodes help to prepare the cell for cytokinesis by positioning precursors of the cytokinetic contractile ring, and the septation initiation network (SIN) regulates the onset of cytokinesis and septum formation. Previous work has noted that one type of interphase node disappears during mitosis providing ...

A phenomenological description of martensitic transformation is proposed on the basis of such parameters as: a degree of lattice coherency between austenite and martensite phases, mobility of interphase boundaries, elastic energy stored during martensitic transformation and degree of its relaxation. Son),: experimental results confirming the proposed ideas are presented.

A gravitationally stable boundary between two polymer solutions in a ternary system can develop into an interphase of structured convectional flow. The transport over this interphase is by counter-current distribution and as a result high-molecular weight material moves by bulk-flow and much more rapidly than low-molecular weight material, which is transported essentially by ordinary diffusion.

RNA has been proposed to be a component of an underlying nuclear matrix. Hall et al. show that noncoding, repetitive RNAs, some derived from LINE1 elements, stably associate with interphase chromosomes and copurify with nuclear scaffold, indicating that RNAs might impact interphase chromosome architecture.
