(10) Ten tissue sections from 10 examples of Bowen's disease were excised from paraffin blocks, rehydrated, and incubated in 90% formic acid at 45 degrees C for 18 h. The epidermis was gently removed with the aid of a dissecting microscope, and the remaining dermis with attached basal lamina was processed for scanning electron microscopy.
(11) Monoclonal antibody studies performed on biopsy specimens from both patients revealed 70% to 100% cells staining with CD5, 80% to 90% staining with CD4, 30% to 50% staining with CD8, and an increase in CD1-staining cells in the papillary dermis, indicating a predominantly helper T-cell infiltrate.
(12) The pathologic findings were dominated by lymphocytic inflammation around centrally placed follicles evolving to follicular necrosis that extended to the perifollicular epidermis and dermis.
(13) Similar vacuoles were also observed in the epidermal intercellular spaces and within the dermis.
(14) Acitretin flux through tape-stripped monkey skin and dermis was only slightly higher than through intact skin.
(15) Two had multiple nodules and the third had a single, recurrent lesion in the dermis or subcutis of the distal extremities.
(16) The increase of PGD synthetase activity in 3-week-old rats was mainly due to the increase of specific activity of PGD synthetase in the epidermis, which was separated from the dermis by heat treatment (55 degrees C, 30 s).
(17) This collagen appeared present throughout the whole dermis with slight variations at 4 months, where there was less extracellular collagen near the hair bulbs.
(18) The key assumptions are (1) that the target site is in the lower epidermis (basal layer) or in the dermis, and (2) that it is the thermodynamic activity (i.e., the free drug concentration, C*, of the active drug species) at the target site that is the true correlate of drug effectiveness.
(19) In initial lesions, CD1a+ cells represent up to 50-60% of the infiltrating cells of the dermal compartment, in several cases being preferentially localized in the upper part of the papillar dermis close up to the epidermal CD1a+ cells in basal position, whereas in chronic psoriasis they represent less than 10%.
(20) An antiserum raised in Rabbits against brain glycoprotein precipitated an identical antigen in faetal dermis and intestine extracts, and also in non nervous tumors (breast adenocarcinomas and adenofibromas, ovarian cystadenoma, gastric and colonic adenocarcinomas, hepatomas, malignant melanomas, rhabdomvosarcoma, fibrosarcomas).
Endodermis
Definition:
(n.) A layer of cells forming a kind of cuticle inside of the proper cortical layer, or surrounding an individual fibrovascular bundle.
Example Sentences:
(1) Bacteria in the stele remained viable after a 6-h treatment of roots with chloramine-t, indicating that the endodermis was intact.
(2) By following the fate of the Casparian strip through numerous divisions of the endodermal cell, information has been obtained relating to the minimum contribution of the endodermis to the root primordium structure.
(3) (ii) The cells interpolate new microtubules at a rate which is characteristic of the cell, and, in the endodermis, of the face of the cell, while the cell elongates.
(4) Bacteria were observed between and in cells of the cortex, in intercellular spaces between the cortex and endodermis, in xylem cells, and in and between pith cells.
(5) An endodermis separated the inner tissues of the nodule from the surrounding cortex.
(6) Histochemical localization of GUS activity showed that the HRGPnt3 promoter was transiently induced in the pericycle and endodermis, specifically in the discrete, small subset of cells involved in the initiation of lateral roots.
(7) were prepared for electron microscopy so that cortical microtubules could be counted along the longitudinal walls in cell files in the endodermis, pericycle, and inner and outer cortex, and in sieve and xylem elements.
(8) The lack of expression of GS-GUS in the outer cortex of the nodules suggests that ammonia may not be able to diffuse outside the endodermis.
(9) This suggests that the linkage of the pectic substances within the wall is mainly by calcium bridges in the intercellular junctions of most types of cells under study (epidermis, subepidermis, fiber layer, and endodermis) and in the outer part (close to the cuticle) of the wall of the epidermal cells.
(10) Particular attention was directed to the outermost primordium cells, derived by meristematic activity from the endodermis, and to the contiguous cortical parenchyma cells.
