The differentiation-specific keratins (K1 and K10) are induced between 9 and 10 weeks, when a third layer of cells (stratum intermedium) forms between the basal and periderm layers.
There was no evidence of a difference in the survival curves between study arms within either stratum of CD4+ cell count (CD4+ cell count less than 50 cells/μl P = 0.32, CD4+ cell count at least 50 cells/μl P = 0.39).
The endocarp consists of several strata of sclerenchymatous cells which become enlarged, lose their content and rapidly widen the walls; we then have a stratum of parenchymatic cells and, finally, we see the pluristratified internal epidermis (Fig. 2D).
The folding is formed by a thick stratum of columnar cells; the prevalent orientation of the long axes of their nuclei is perpendicular to the basement membrane (Figs. 5b and 8a).
There was no evidence of a difference in mortality rates between those who received home-based care compared with those who received facility-based care in either stratum of CD4+ cell count.
Relative risks for malaria in HIV-infected persons, derived from literature review, were applied to the HIV-infected population in each country, by age group, stratum of CD4 cell count, and urban versus rural residence.
The epithelium, the most anterior corneal layer, contains 6 8 strata of epithelial cells.
The domain of En1 expression essentially overlaps spatially and in its gradiental aspect that of En2, but expression extends also to the periventricular and intermediate strata of serotonergic cells in the mantle.
In crocodiles and turtles there is continuous cell division in the stratum germinativum and exfoliation of cells at the skin surface.
Figure 2 shows changes over time in the proportions of patients starting cART within different strata of CD4-cell counts according to the region of residence.
