    Notes: Abstract This study examined the effects of a smoking cessation intervention on stages of change in 349 low-income, pregnant women. At first prenatal visit, women were randomized into experimental or usual care condition and classified by stage of change: precontemplation, contemplation, preparation, or action. For each stage of change at the first prenatal visit, the stage distributions of the experimental and usual care groups were compared at the second and 36-week prenatal visits. Kruskal-Wallis tests revealed significant differences at the second visit in the stage distributions by condition for subjects who were initially in precontemplation or in preparation. In each case, a greater proportion of experimental than usual care subjects advanced through the stages. The shift was not maintained at the 36-week visit.

    Notes: Summary The expression of two previously uncharacterized polypeptides produced in epidermal cells of chick reticulate and scutate scales during late embryonic scale histogenesis and in hatchling birds has been studied biochemically and immunologically. These polypeptides have been identified by two-dimensional pH gradient gel electrophoresis as basic in charge, with apparent molecular weights of 20 and 23 kD, and they have been characterized immunologically and by amino acid analysis as non-keratin in nature. Monoclonal antibodies which react with both polypeptides have been used for immunohistochemical and immunogold electron-microscopic localization. Immunoreactivity was observed in suprabasal cells of reticulate scale epidermis, where it codistributed with bundles of α-type cytokeratins in the α-keratin-rich layers of epidermis known as the alpha stratum and in suprabasal cells of the outer epidermal surface of scutate scales, where it codistributed with α-and β-type keratin filament bundles in the β-keratin-rich layers of epidermis known as the beta stratum.

    Notes: Summary The outer surface of adult Gallus domesticus scutate scale was studied as a model for epidermal cornification involving accumulation of both alpha and beta keratins. Electron-microscopic analysis demonstrated that the basal cells of the adult epidermis contained abundant lipid droplets and that filament bundles and desmosomes were distributed throughout the cell layers. Indirect immunofluorescence microscopy and double-labeling immunogold-electron microscopy confirmed that the stratum germinativum contained alpha keratin but not beta keratin. Beta keratins were first detected in the stratum intermedium and were always found intermingled with filament bundles of alpha keratin. As the differentiating cells moved into the outer regions of the stratum intermedium and the stratum corneum, the large mixed keratin filament bundles labeled increasingly more with beta keratin antiserum and relatively less so with alpha keratin antiserum. Sodium dodecyl sulfate-polyacrylamide gel analysis of vertical layers of the outer surface of the scutate scale confirmed that cells having reached the outermost layers of stratum corneum had preferentially lost alpha keratin. The mixed bundles of alpha and beta keratin filaments were closely associated with desmosomes in the lower stratum intermedium and with electron-dense aggregates in the cytoplasm of cells in the outer stratum intermedium. Using anti-desmosomal serum it was shown that these cytoplasmic plaques were desmosomes.
