The nucleoli that were generally arranged to form a regular layer in the nuclear envelope of normal grooving previtellogenic oocytes were distributed irregularly in the nucleoplasm. Atretic oocytes at the secondary growth phase were divided into 3 stages, namely: atretic oocytes at stage three, four and five.
The cytosol and nucleoplasm of RBCs from control fish appeared uniform in the TEM images, indicated by the typical smooth appearance of non-polymerized Hb (Fig.
The cells contained an oval, electron dense nucleus in which heterochromatin was seen as small clumps dispersed in the nucleoplasm with peripheral condensation (Figures 2(a), 2(b), 2(c), and 2(d)).
Therefore, loss of the integrity of melanosome membranes with leakage of toxic melanin particles, intermediates of melanogenesis and reactive oxygen species into the cytoplasm and nucleoplasm of melanocytes, may render these melanocytes prone to an increased risk of DNA damage and consequently to malignant transformation (Figure 1) [10].
Furthermore, in mouse embryonic stem cells (mESCs), the coilin dispersed in the nucleoli and accumulated in CBs was characterized by a reduced mobile fraction compared to the GFP-tagged coilin in the nucleoplasm [10].
NF-[kappa]B translocation from the cytoplasm to karyoplasm (nucleoplasm) was determined by comparing the amounts of protein in dermal papilla cells and lamin B.
Additionally, the amount of cytoplasm the cell makes decreases relative to the amount of nucleoplasm, so that the cell diameter decreases and there is an actual increase in nuclear size which may be related to an increase in the nuclear contents required for replication.
GCI with reperfusion caused pronounced degenerative changes and massive neuron death in the hippocampal CA1 region in rats of control group while neurons of sham-operated rats had homogenously stained cytoplasm and nucleoplasm with clearly visible nucleoli (Fig.
The general effect of those three [Ca.sup.2+] modulation parts provides a background of relatively low [Ca.sup.2+] level in cytosol and nucleoplasm at rest while rapid [Ca.sup.2+] level elevation after activated.
