    Keywords: Salivary glands -- Congresses. ; Electronic books.
    Description / Table of Contents: Salivary Glands and their Secretions covers the proceedings of the conference held at the University of Washington in Seattle, Washington, U.S.A. The book focuses on the structure and functions of secreting organs and the composition, mechanism, and control of secretions. The selection first reviews the comparative aspects of the structure and functions of the salivary glands; electron microscopy of induced changes in the salivary glands of rats; and the action of thyroid and adrenal glands on the submaxillary glands of mice. The book then takes a look at hormonal influences on the cytology and physiology of salivary glands and hormones and inanition. The book ponders on studies on the physiology of rat and mouse submaxillary glands and hormonal control of the nerve growth factor content in the submaxillary glands of mice. The text also examines central nervous representation of salivary secretion, secretory nerves of the salivary glands, and changes in salivary flow produced by variations in fluid and electrolyte balance. The selection is a valuable source of data for readers interested in the structure and functions of the salivary glands.

    Notes: In weanling rats, after receiving a zinc-deficient diet (〈1 ppm) for 4 wk, the buccal mucosa appears hyperplastic. This study determines changes at earlier stages of the lesion. After 9 days of deficiency, the keratin layer had partially converted to parakeratosis and thickened, and the size of the capillary bed was increased. After 18 days, the keratin layer was fully parakeratotic and thickened further. The cellular layer was thickened. The mitotic rate was doubled and rate ridges were convoluted. After 27 days, the keratin and cellular layers were further thickened, and the mitotic rate remained elevated. The rate ridges were further convoluted. The number of mast cells was doubled and the size of the vascular bed had increased further. These findings suggest early and late interactions between the epithelium and lamina propria. After four days on a control diet following 27 days of zinc deficiency, the mucosa returned normal.

    Notes: Abstract Incisional wounds of the same length and depth were made on tongue and dorsal skin of rats and the fine structural aspects of the responses of these were compared. Comparisons were made between the timing and degree of phagocytosis, the timing and rate of epithelial cell migration, of overall rate of healing, and of reformation of basal lamina and attachment complex in these two tissues. Phagocytic activity in epithelium and connective tissue of mucosa reached higher levels than in skin and the peak of activity in the epithelium of the mucosa was earlier than in the epidermis. Mononuclear phagocytes were active in phagocytosis, neutrophils showed little phagocytic activity-Epithelial migration was found to begin earlier in mucosa than in skin. Epithelialization of the wound and repair of supporting tissue were completed earlier. The same sequence in the renewal of ultrastructural components of the hemidesmosome-attachment complex was found in skin and mucosa, but was completed earlier at the mucosal site.Mechanical and physical as well as physiologic factors may play a role in determining the differing rates of repair in mucosa and skin.

    Notes: Summary Some of the parameters affecting the staining of keratinized oral epithelium with the zinc iodide-osmium reaction were examined using light and electron microscopy and electron probe microanalysis. Factors examined were block size, incubation temperature and the effect of aldehyde prefixation. Large blocks (4 mm cube) were subdivided after incubation and the staining of the centre and edge compared. Generally the reaction was more variable at the edge than in the centre. Small blocks (1 mm cube) showed a more intense reaction when incubated at 24°C than at 4°C. In all these preparations, final reaction product was seen over Golgi systems, lysosome-like bodies, membrane-coating granules and, in the more intensely stained regions, over endoplasmic reticulum and nuclear membranes as well. In prefixed material, mitochondria were frequently stained in addition to the other organelles. Energy dispersive analysis showed the reaction product to be similar in all preparations and to contain high levels of zinc and osmium but not iodine.

    Notes: Organ culture of 19-day-old chick embryo duodena was utilized to evaluate the mechanism of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3)-dependent calbindin-D28k (CaBP) expression. Duodenal CaBP and 1,25(OH)2D3 receptor (VDR) expression were assessed by Western blot analysis, while CaBP and VDR mRNA levels were determined by Northen blot analysis. In untreated duodena, both VDR protein and mRNA were present, while CaBP protein and mRNA were undetectable. Treatment of cultured duodena with 25 nM 1,25(OH)2D3 resulted in detectable CaBP mRNA after 4 h which continued to increase during a 24 h time period. Under these conditions, localization of [3H-1β]1α,25(OH)2D3 in duodenal chromatin is rapid (≤ 30 min). Thus, the delayed accumulation of detectable CaBP mRNA cannot be explained by slow nuclear binding of 1,25(OH)2D3. The inclusion of 1.6 μM actinomycin D in the organ culture partially inhibited the 1,25(OH)2D3-regulated increase in CaBP mRNA, which implies that there is a transcriptional component involved in the increased CaBP mRNA levels. Similarly, quantitative polymerase chain reaction studies allowed the detection of CaBP pre-mRNA and mRNA sequences 1 h after hormone treatment, suggesting that CaBP gene transcription is initiated rapidly. Treatment of cultures with 36 μM cycloheximide 1 h prior to 1,25(OH)2D3 addition resulted in superinduction of VDR mRNA levels but sharply reduced CaBP steady-state mRNA levels. This dramatic reduction in CaBP mRNA reveals that 1,25(OH)2D3-mediated CaBP expression is dependent on ongoing protein synthesis. Thus, we propose that a labile auxiliary protein or other cofactor, which may or may not be 1,25(OH)2D3-dependent, is necessary for 1,25(OH)2D3-mediated CaBP gene transcription in chick duodena.

    Description: Background: Interleukin-27 (IL-27) has been described to be highly expressed during the very first days after birth, but secretion of IL-27 by dendritic cells during the course of childhood has not been described.FindingsIn our present study we enrolled children (n = 55) in the range from 1 day of to 18 years of age and asked for a small whole blood sample. The capacity of dendritic cells to produce IL-27 during childhood was measured after whole blood culture with or without inflammatory stimuli. Results support recent findings of high IL-27 levels after birth and lowest levels in adults. Interestingly, we detected an interim peak production level at early adolescence. Conclusion: These data hint to prominent roles of IL-27 at the very start of post-natal life. Furthermore, a link has been given to so far not described immunological events during puberty.

    Description: Current research revealed distinct changes in ecosystem functions, and thus in ecosystem stability and resilience, caused by changes in community structure and diversity loss. Even if benthic species play an important role in benthic-pelagic coupling e.g. through the remineralization of deposited organic material, the long-term variability of traits and functions is largely unknown. By using abundance and bioturbation potential of macrofauna samples, taken along a transect from the German Bight towards the Dogger Bank annually in May in 1990 and from 1995 to 2017, we analysed the taxonomic and trait-based macrofauna long-term community variability and diversity. Taxonomic and trait-based diversity remained stable over time, while three different regimes were found, characterised by changes in taxonomic and trait-based community structure. Min/max autocorrelation factor analysis revealed climatic variables, nitrite, and epibenthic abundance as most important environmental drivers for taxonomic and trait-based changes.
