nucleolus

The chromatin nucleolus, early chromatin perinucleolus and late chromatin perinucleolus oocytes were observed in the previtellogenic stage, (Figs.

Nucleolus identification was recorded with a score: 1 if present and 0 if not.

They found that aspirin blocks a key molecule (TIF-IA), which is essential for the nucleolus to function.

In the cell nests, oogonia are distinguished by having slightly basophilic spherical to oval nuclei, an evident nucleolus and scarce ooplasm (Fig.

In control seeds with 4% moisture content, the results showed that the cellular structure was complete, with normal cytoplasmic membrane, intact nucleus, clear nuclear nucleolus, clearly visible nuclear membrane, normal mitochondria and cristae (Fig.

After sampling the nucleolus, a flat intercept was considered from the central point within the nucleolus.

The Chromatin nucleolus oocytes (STAGE I) (Figure 1) were the smallest oocytes, appearing grouped in 'clusters of germ cells' (CG) inserted in ovigerous lamellae in vascularized areas, with average diameter ([+ or -] SD) of 9.5 [+ or -] 4.46 [micro]m (Figure 5).

The nuclear chromatin is dispersed and the nucleolus is often inconspicuous.

The proventriculus consists of a single-layered epithelium of cuboidal cells each with a central nucleus containing decondensed chromatin and a prominent nucleolus. The luminal surface of the cells is coated by a thick cuticle, which has projections forming chitinous teeth, while the basal portion of the epithelium is surrounded by well-developed muscle layers (Figs.

McCain (game theorist, Drexler U.) considers value solutions for superaddidive transferable utility games in coalition function form, then moves to the issue of Zeuthen-Nash bargains, nontransferable utility games and games in partition function forms, proposes a Shapley value algorithm for games in partition function forms, and then extends the nucleolus to nontransferable utility games in partition function form.

Electron Microscopy.--The electron micrographs, of the untreated mouse mammary tumor cells were bounded by delicate plasma membranes and displayed large nuclei containing uniformly distributed euchromatin and conspicuous marginal heterochromatin abutting the nuclear membrane and a prominent nucleolus (Figs.

Oogonia displayed round nuclei of about 10 [micro]m, which stained light to dark blue with hematoxylin-eosin, as well as a strong basophilic nucleolus with an average size of 4 [micro]m.

The disc is made up of an annulus fibrosis with a nucleolus pulpous found within the fibrosis (these are liquid filled 'sacs' that act as shock absorbers).
