A control mechanism that limits nuclear division is pres ent in contact-inhibited nontumorigenic mouse BALB/3T3 cells and mouse embryo fibroblasts. In the absence ofcytoplasmic division, 3T3 and mouse embryo fibroblast cells may undergo nuclear division once or occasionally twice and then stop. Also, there is no increase in the frequency of premature chromosome condensation. In non-contactinhib...

Apoptotic execution is characterized by dramatic changes in nuclear structure accompanied by cleavage of nuclear proteins by caspases (reviewed in [1]). Cell-free extracts have proved useful for the identification and functional characterization of activities involved in apoptotic execution [2-4] and for the identification of proteins cleaved by caspases [5]. More recent studies have suggested ...

We study the influence of a high density behaviour of the nuclear symmetry energy on a kaon condensation in neutron stars. We find that the symmetry energy typical for several realistic nuclear potentials, which decreases at high densities, inhibits kaon condensation for weaker kaonnucleon couplings at any density. There exists a threshold coupling above which the kaon condensate forms at densi...

We construct the nuclear and quark matter equations of state at zero temperature in an effective quark theory (the Nambu-JonaLasinio model), and discuss the phase transition between them. The nuclear matter equation of state is based on the quark-diquark description of the single nucleon, while the quark matter equation of state includes the effects of scalar diquark condensation (color superco...

Geometric and densitometric properties of the Barr body of early and late phase II confluent human fibroblasts are analysed by the automated image analyser Quantimet 720 D. In cells with the same 2C DNA content, the state of condensation of the Barr body varies proportionally wih the state of condensation of the entire nucleus yielding a correlation between nuclear and Barr body area. In light ...

Low-energy nuclear reactions in micro/nano-scale metal particles are described based on the theory of Bose–Einstein condensation nuclear fusion (BECNF). The BECNF theory is based on a single basic assumption capable of explaining the observed LENR phenomena; deuterons in metals undergo Bose–Einstein condensation. The BECNF theory is also a quantitative predictive physical theory. Experimental t...

Transmission electron microscopy (TEM) revealed several ultrastructural changes induced by exposure to cadmium in ciliated protozoan, Stylonychia mytilus. The main cytoplasmic alterations in the post treated cells were:-condensation of the ground cytoplasm, mitochondrial disorganization, cytoplasmic vacuolization, accumulation of electron dense bodies and autophagosome formation. At the nuclear...

In this paper, a new nano-size ionic liquid (nIL) has been synthesized from D-phenylalanine and oxalic acid (D-Phe-OX) via a simple procedure. The obtained nIL has been characterized by the fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDAX), thermogravimetric analysis (TGA), nuclear magnetic resonance spectroscopy (1</sup...

Chromosome condensation is essential for the faithful transmission of genetic information to daughter cells during cell division. The depletion of chromosome scaffold proteins does not prevent chromosome condensation despite structural defects. This suggests that other factors contribute to condensation. Here we investigated the contribution of divalent cations, particularly Ca2+, to chromosome...
