The effects of hyperthermia on chromatin condensation and nucleoli disintegration, as visualized by induction of premature chromosome condensation in interphase mammalian cells, was studied in exponentially growing and plateau phase Chinese hamster ovary cells. Exposure to heat reduced the ability of interphase chromatin to condense and the ability of the nucleolar organizing region to disinteg...

The equation of state and the properties of neutron stars are studied for a phase transition to a charged kaon condensate. We study the mixed phase by using Gibbs condition with comparison to the hitherto applied Maxwell construction. Implications for kaon condensation and for the mass-radius relation of condensed neutron stars are examined. The high density behavior of the equation of state of...

The present status in the field of strange mesons nuclei and neutron stars is reviewed. In particular, $\bar K N$ interaction, that governed by presence $\Lambda(1405)$, analyzed formation NN$ bound state discussed. Moreover, properties K$ dense nuclear matter are studied, connection with strangeness production collisions kaon condensation stars.

Chromosome condensation during cell division is one of the most dramatic events in the cell cycle. Condensin and topoisomerase II are the most studied factors in chromosome condensation. However, their inactivation leads to only mild defects and little is known about the roles of other factors. Here, we took advantage of Drosophilaoocytes to elucidate the roles of potential condensation factors...

The organization of rat liver nuclei in vitro depends on the ionic milieu. Turbidity measurements of nuclear suspensions in the presence of varying concentrations of divalent cations have been correlated with nuclear ultrastructure. The concentration of MgCl2 (2 mM) at which turbidity of nuclear suspensions is maximal and chromatin condensation appears most extensive is the same concentration t...

[Abstract] A PC code based on the quantum mechanical Langevin equation to simulate dynamic motion of deuterium (or hydrogen) cluster with three dimensional symmetry has been developed for studying very fast condensation or oscillation behavior in time-step of 0.001 as (1.0E-21 second) for overall time interval of several fs to 500 fs. Some numerical results are typically shown for two cases of ...

Apoptosis and necrosis are considered conceptually and morphologically distinct forms of cell death. Here, we report that demise of human T cells caused by two classic apoptotic triggers (staurosporin and CD95 stimulation) changed from apoptosis to necrosis, when cells were preemptied of adenosine triphosphate (ATP). Nuclear condensation and DNA fragmentation did not occur in cells predepleted ...

Sperm concentration, morphology, DNA condensation and nuclear protein pattern as well as sperm adenylate cyclase were evaluated in semen samples provided by 7 volunteers every 8 h for 2 days. During the observation period, sperm concentration and total sperm number decreased but began to return towards normal after a 3-day abstinence period. No increase in the proportion of immature sperm cells...
