Example Sentences:
(1) We report the nucleotide sequence of eveC, a cnidarian eve-class homeobox; this is the first homeobox to be identified in any diploblastic organism, and is only the second eve-class in an invertebrate.
(2) Triploblasts and diploblasts formed two clearly separated monophyletic units; this divergence, which apparently preceded the diversification of diploblastic animals (i.e.
(3) These results do not exclude the possibility that triploblasts and diploblasts arose independently from different protists.
(4) In order to study the origin of metazoans, we have compared sequences from the 5' end of the large subunit ribosomal RNA of a number of protists, fungi, plants and metazoans, including all diploblastic phyla (sequences of 10 new species have been determined, including that of the placozoan, Trichoplax adhaerens).
(5) the successive sponge, ctenophore, cnidarian radiations), showed a much more ancient origin of triploblasts with respect to diploblasts than classically assumed.
(6) We report here the first homeoboxes from cnidarians, a phylum of diploblastic organisms thought to occupy a near-basal position in metazoan phylogeny.
(7) From this analysis, several inferences on the eukaryogenesis can be made among which the ancient origin of the cytoskeleton, the late occurrence of the chloroplastic endosymbiosis and the simultaneous emergence of the triploblastic and diploblastic metazoan patterns.
(8) Sequences from the 5' end terminal part of 28S ribosomal RNA were obtained and compared for 22 animals belonging to all diploblastic phyla and for a large number of representatives of triploblastic Metazoa and protists.
(9) Short internodes between these radiations suggested an early rapid diversification of diploblasts.
Embryonic
Definition:
(a.) Of or pertaining to an embryo; embryonal; rudimentary.
Example Sentences:
(1) Brain and ganglia of embryonic Periplaneta americana were grown for 2 to 3 weeks in a chemically defined medium.
(2) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(3) Right orchiectomy and retroperitoneal lymph node dissection for embryonal carcinoma had been performed 5 years earlier.
(4) Blocks of hippocampal tissue containing the fascia dentata were taken from late embryonic and newborn rats and transplanted to the hippocampal region of other newborn and young adult rats.
(5) In conclusion, autoimmune thyroiditis in an animal model can be prevented by reducing thyroidal iodine or its metabolism and optimal effects require intervention at the embryonic stage.
(6) On embryonic day 3.5 (E3.5), 1 day after surgery, there is a 42% average increase in volume of the polyganglia compared with the corresponding DRG on the unoperated side.
(7) Isoenzyme LDH4 was absent in the human pancreas in all the studied periods of embryonic development.
(8) The mRNA data of the developing gut correspond with previous protein data, which showed that the shorter Mr 210,000 polypeptide predominates during earlier developmental stages and the larger Mr 260,000 polypeptide appears later in the embryonic gut (Aufderheide, E., and P. Ekblom.
(9) Almost nothing is known about nature and timing of the embryonic cues which induce or initiate spicule formation by these cells.
(10) Implantation is dependent on embryonic age and is independent of endometrial maturation within this window.
(11) The junctional currents were already constant 1 ms after step changes in the junctional voltage; this was three orders of magnitude faster than the other known examples of voltage-controlled gap junctions between embryonic cells.
(12) Zona pellucida solubility, plasminogen activator production, and plasminogen conversion to plasmin increased as embryonic stage advanced; however, plasminogen activator production and plasmin conversion to plasmin were poorly correlated with zona pellucida solubility.
(13) He fashioned alliances with France in the 1950s, and planted the seeds for Israel’s embryonic electronics and aircraft industries.
(14) Both kinds of experiments show that 1, 25-(OH)2D3 has effects on embryonic bone which are typical for high concentrations of parathyroid hormone (PTH).
(15) p50B is able to form heteromeric kappa B-binding complexes with RelB, as well as with p65 and p50, the two subunits of NF-kappa B. Transient-transfection experiments in embryonal carcinoma cells demonstrate a functional cooperation between p50B and RelB or p65 in transactivation of a reporter plasmid dependent on a kappa B site.
(16) At the adult neuromuscular junction, acetylcholine (ACh) receptors are highly localized at the subsynaptic membrane, whereas, embryonic myotubes before innervation have receptors distributed over the entire surface.
(17) Embryonal carcinomas were found in 15 tumours, two being of pure type and the remaining 13 a part of mixed tumours.
(18) A large portion of the N-terminal globule of human collagen VI was prepared from the culture medium of stably transfected human embryonic kidney cell clones.
(19) The tissues were derived from the three germ layers and were prevalently mature; only a bit of them was represented by embryonic mesenchymal tissue.
(20) Phosphotyrosine-modified proteins were also abundant in and highly restricted to the process-rich layers of the embryonic optic tectum.
