    Biochemical characterization of 1,25(OH)2D3 receptors in chick embryonal duodenal cytosol (1982)
    Springer
    Calcified tissue international 34 (1982), S. 265-269 
    Details
    ISSN: 1432-0827
    Keywords: 1,25(OH)2D3 Receptor ; Chicken Duodenal Cytosol ; Chicken Embryo ; Affinity ; 1,25(OH)2D3 Concentration

    Topics: Biology , Medicine , Physics
    Notes: Summary This study presents measurements of serum vitamin D metabolites, calcium and phosphorus as well as measurements of the equilibrium dissociation constant for duodenal 1,25(OH)2D3 receptor in 15-, 18-, 19-, and 20-day chick embryos in comparison to that in 1- and 118-day-old chicks and to vitamin D-deficient chicks. The present results showed that: (a) serum 1,25(OH)2D and 24,25(OH)2D levels rise from 15 and 18 to days 19 and 20 of embryonic development while serum phosphate levels are stable; (b) serum calcium levels rise at hatching to adult levels; (c) the duodenal 1,25(OH)2D3 receptor is detectable in 15-day-old embryo and has a Kd similar to that of 118-day-old vitamin D-replete chicks; and (d) the activity of 1,25(OH)2D3 receptor in chick duodenal cytosol is maximal at hatching.

    Fine structure of the olfactory epithelium in the goldfish, Carassius auratus (1977)
    Springer
    Cell & tissue research 183 (1977), S. 445-455 
    Details
    ISSN: 1432-0878
    Keywords: Olfactory epithelium ; Goldfish ; Retrograde degeneration ; Olfactory receptor cell ; Electron microscopy

    Topics: Biology , Medicine
    Notes: Summary The fine structure of the goldfish olfactory epithelium was studied by transmission and scanning electron microscopy. Six different cell types were distinguished. Identification of the olfactory receptor cell was accomplished by use of retrograde degeneration studies. Two morphologically distinct types of olfactory receptor cells were identified: one type bears radially oriented cilia (Type I cell); the other type bears microvilli (Type II cell). The other four cell types were not identifiable as olfactory receptor cells: they are ciliated cells (Type III), rod-shaped cells (Type IV), supporting cells (Type V), and basal cells (Type VI).

    Electron microscopic study of the termination of the centrifugal fibers in the goldfish olfactory bulb (1979)
    Springer
    Cell & tissue research 197 (1979), S. 257-262 
    Details
    ISSN: 1432-0878
    Keywords: Centrifugal fibers ; Olfactory bulb ; Goldfish ; Degenerating synapses ; Electron microscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The terminals of centrifugal fibers to the olfactory bulbs of goldfish were studied by electron microscopy after transection of the medial, lateral or entire olfactory tract. The centrifugal fibers originate in the telencephalic hemisphere, pass through both the medial and the lateral olfactory tract, and form synaptic contacts with dendrites in the granule cell layer.
