Nacreous
Definition:
(a.) Consisting of, or resembling, nacre; pearly.
Example Sentences:
(1) When nacreous shell produced by the marine oyster Pinctada maxima, used as a biomaterial in oral surgery, is implanted in human bone, new bone formation occurs, resulting in a tight welding of the bone to the nacre [16].
(2) Etching with the glutaraldehyde-acetic acid solution reveals that the nacreous tablets in Mytilus, Nucula, and Unio are composed of four crystal individuals which occur in two structurally different pairs and which are probably cyclically twinned.
(3) The crystalline phases at the first few lamellae were mostly imperfect while the whole nacreous layer acquitted itself into a highly oriented biomineralized aragonite.
(4) From these morphological observations, a regulatory role for the various periostracal layers in mineral trapping, nucleation, and the subsequent formation of the prismatic and nacreous layers of the shell can be postulated.
(5) In all three genera, the nucleation of new nacreous tablets invariably takes place on the top surface of the less-soluble crystal individuals.
(6) Transmission electron microscope studies of the cellular nucleation sites of a biomineralized calcium carbonate(aragonite) in the lamellar nacreous layer of the bivalvia Cristaria plicata (Leach) shell showed that the low density calcium particles were confined within some large vesicles of the bivalve mantle cells on which the crystalline aragonite phases were deposited.
(7) The stack-like growth of the nacreous tablets in the marginal region of the shell in Nucula is probably related to the exceptionally large-sized, less-soluble crystal individuals in the nacreous tablets of this region.
