Exuviate
Definition:
(v. i.) To shed an old covering or condition preliminary to taking on a new one; to molt.
Example Sentences:
(1) During the process of emergence this gas moves into the exuvial space through the adult spiracles and then follows the exuvial fluid into the alimentary canal.
(2) We investigated the involvement of the enzyme, carbonic anhydrase, in the calcification-decalcification processes occurring in the posterior caeca of the midgut of the terrestrial crustacean, Orchestia cavimana, before and after exuviation.
(3) Reduction of the apical cell membrane of the tormogen cell after apolysis permits unrestricted growth of the new hair into the exuvial space.
(4) It was presumed that the stage III larva had exuviated in the human stomach.
(5) In post-exuvial period, we found only weak specific reaction products, thus indicating a reduced active calcium transport as these ions are rapidly reabsorbed down the concentration gradient.
(6) For both ATPases as well as alkaline phosphatase, the specific reaction products were most intense during the pre-exuvial period, i.e.
(7) This enzyme was ultrahistochemically localized throughout the membranes of the caecal epithelium as well as extracellularly, i.e., within pre-exuvial calcareous concretions and postexuvial calcified spherules.
(8) This fluid begins to disappear from the exuvial space approximately 9-10 h before the actual shedding of the integument.
(9) Acetazolamide treatment in vivo inhibited about 50% of the calcium uptake during both pre-exuvial secretion and postexuvial reabsorption.
(10) We argue that the potassium salt solution, formed in the exuvial space (as water presumably follows the actively transported potassium), has three functions (1) to accomplish the gel--sol transformation, (2) to activate the gel enzymes and (3) to buffer the enzyme solution at a pH favourable to the activity of the gel enzymes.
(11) The exuvial side of the pharate pupal integument is usually positive to the haemolymph-side, both in vivo and in vitro, during the period when the moulting fluid is being secreted.
(12) In a normal 32 mM KHCO3 saline, potential difference (PD) is around 10 mV, exuvial side positive, and short-circuit current (SCC) is 15-20 microA cm-2.
