The problem of how to interweave the primordial+particularistic orientations with the universalistic constituted in all these civilizations a potential point of contention. The staining intensity in oocytes of primordial and primary follicles was stronger than in late-staged follicles. Their expression has been detected in the human fetal ovary (cleaved caspase-3) between 14-19 weeks, a time leading to primordial follicle formation.

The weekly market is as much an anchor linking a particular community to a particular space as are so-called primordial structures of lineage and village. As far as the concept of culture was concerned, two primordial group identities gradually emerged among the wide diversity of viewpoints and approaches. Their primordial sentiments were the primary shapers of their psychological ties. All that exists - including the rational soul - is an emanation from the primordial unity. Shortly after fertilisation of the egg and during the earliest stages of vertebrate embryogenesis a finite number of non-dividing primordial germ cells are produced. In a 68.2 cm fetus, the number of preantral follicles increased rapidly (primordial follicles, 35 840; primary follicles, 1530). Primordial follicles had already appeared in a 20 cm fetus and primary follicles were observed in a 50 cm fetus.

There is some uncertainty in the literature as to when the primordial follicle first appear. Derivation of pluripotent stem cells from cultured human primordial germ cells. Apoptosis in mouse primordial gene cells: a study by transmission and scanning electron microscopy. At this stage they become surrounded by a few nonproliferating flat follicle cells forming a unit called the resting or primordial follicle. Particularly in large crisis situations, remarkably primordial political emotions can erupt even among the well-educated. In some mammalian species, the formation of primordial follicles occurs around the time of birth, whereas in others folliculogenesis begins during fetal life. In the histological sections, the slices contained only follicles at primordial and primary stages (b). More rounded outline as compared with the primordial germ cell. What happens to the cords when primordial follicles are fully formed? Primordial follicle assembly refers to the process by which primordial follicles are formed. Cellular interactions that control primordial follicle development and folliculogenesis. He forcef ully argues that it was not an expression of primordial loyalties and identities that somehow failed to make the transition to nationalism. Maturation of mouse primordial follicles by combination of grafting and in vitro culture. The oocyte diameters in the primordial and primary follicles did not change after grafting. They are considered primordial grains and seeds of interplanetary dust ; because of their extreme stability and inertness they remained unaltered for billions of years. They access a range of other options, none of which, certainly, are primordial or ignorant. The serpent temples also depict the primordial flood crocodilian, who was both the world and the world destroyer-hence, a symbol of both order and chaos. Our senses are acute and every sound and smell generates warm, primordial emotions. Nonetheless, even in this primordial ooze of randomly generated circuits, some score a better value of fitness than others. The caribou are primordial; we humans do need the wild configured into our lives. First, we believe that there is a functional difference between the original primordial organic world and the transition zone. The resulting 'noise music' accepts the simulatedness of trying to leave music behind in order to return to some more original, primordial sound. On a standard process view, a primordial chaos was the only non-divine reality in existence at the beginning of our cosmic epoch. Secondary follicles were present in the 75.5 cm fetus (primordial follicles, 39 560; primary follicles, 3240; secondary follicles, 160). After migration, primordial germ cells begin their developmental programmes of oogenesis. The establishment of primordial follicles in the mammalian ovary requires individual oocytes to segregate and associate with pregranulosa cells. Therefore, in the reproductive system, the effect of mitochondrial damage on primordial follicles may help to explain the 'maternal age effect'. Individual primordial follicle emerge completely enveloped within continuous basement membrane (follicle breakout). There is controversy in the literature as to when primordial germ cells become oogonia. The present study showed that in bucephalid cercariae the tegumental lining of the primordial definitive excretory pore originates as a separate structure. The first is that of ethnic, 'primordial' links based on birth and kinship. Like primordial desire, wine is natural-that is, wine is anterior to the discontinuity of selfhood, the rules of society, and the categories of cognition. The most general distinction is between the "primordial" and "constructivist" approaches.

The correlation of be like with first person is likely a by-product of the primordial semantic0pragmatic effect, narrators quoting themselves, that is, first person. The preconscious, object-like condition of termless wandering recalls the primordial transience underlying self-awareness, against which the intentional wakefulness of knowledge defines itself. Primordial follicle assembly (first step in follicle formation) determines the lifetime supply of primordial follicles and remains a poorly understood phenomenon. Observations of.the movements of the living primordial germ cells in the mouse. Primordial follicles are formed when primary oocytes become invested with a layer of flattened pre-granulosa cells. Primordial yolk spheres may contain lining bodies and were observed fused with dense tubules and multivesicular bodies or associated with smooth cisternae. The primordial anthropological connexion of musical improvisation and hope is found in shamanism. Because mouse oocytes start to grow after birth, only primordial follicles are present in the ovary of the newborn infant at birth. In the primordial and primary follicles, oocytes were surrounded closely by a layer of squamous and cuboidal granulosa cells, and were morphologically normal. The primordial advantage of "color" vision may have simply been better sensitivity. Despite being a critical process, primordial follicle assembly remains poorly understood.

Primordial follicles appeared (primordial follicles, 30), and primary follicles were present in a 48.9 cm fetus (primordial follicles, 11 070; primary follicles, 490). Changes in the number of primordial follicles were observed in ovaries of different stage fetuses (fetal length 20-120 cm). The rest of the oocytes degenerate during the growth phase or remain in the primordial follicles. Primordial follicles constitute a resting pool of non-growing follicles that will be progressively depleted throughout the reproductive life span of the female. The first, which as seen above is primordial, is the social urge. Why isn't the sea still a primordial battleground of free and independent replicators? Irregular to the point of seeming 'a bit of primordial chaos', it is always a measure of being-as-potential. The labyrinth, that primordial ground plan and image of architectural endeavour, is a projection linking time and place. The custom was, however, a late eighteenthcentury innovation rather than primordial practice. I have argued that this implies that selfhood is a synthesis of primordial and social being. In summary, it is argued that the bodily schema, the primordial unity of the body, is the foundation of a coherent embodied selfhood. What is crucial about songs is the rhythmic and segmental characteristics of the vocal message, and this may make it primordial over early linguistic interaction. In other words, religious affiliations were instrumental, strategic matters rather than expressions of primordial identities or moral-ideological convictions. Even if they do not yield any positive evidence of primordial black holes, they will be very valuable. The idea that the primordial mixture contained seeds of plants and animals takes account of both these points. The primordial chemical reactions and the energy sources, which produced the early constituents of proteins and nucleic acids, have been simulated by many authors. Once primordial follicles enter this phase the first morphological modifications are an increase in oocyte volume accompanied by hypertrophy and hyperplasia of follicle cells.
