High impact information on Anthozoa

• Input of anthropogenic CO2 to the oceans as observed by 13C and 14C isotopes in corals is partially obscured by natural variability [1].
• Here, we show that on the northwest coast of Aceh, Indonesia, where the tsunami was most ferocious, the damage to corals, although occasionally spectacular, was surprisingly limited [2].
• Our results suggest that invertebrate COX gene pairs do not correspond to vertebrate COX-1 and COX-2 and are consistent with duplication of the COX gene having occurred independently in corals, ascidians, and vertebrates [3].
• On the basis of these findings, we assume that alpha 1 alpha 2 alpha 3 heterotrimers arose in evolution with the divergence of Scyphozoa and Anthozoa [4].
• Freeze-fracture of fixed and unfixed tissue, lanthanum tracer and conventional thin-section studies have revealed 2 new types of septate junction in the class Anthozoa, phylum Coelenterata [5].

Biological context of Anthozoa

• Seasonal variations of coral irGnRH, with a dramatic increase during the spawning period, concomitant to that in aromatase and E2, as well as the ability of mGnRH agonist to stimulate coral aromatase, steroidogenesis, and steroid glucuronization suggest that irGnRH plays an important role in the control of oocyte growth and mass spawning in corals [6].
• We measured local and regional patterns of genetic variation in corals along Australia's Great Barrier Reef to determine the relative contributions of sexual and asexual reproduction to recruitment and to infer levels of gene flow both locally (among adjacent sites, < 5 km apart) and regionally (among reefs separated by 500-1,200 km) [7].
• Characterizing stress gene expression in reef-building corals exposed to the mosquitoside dibrom [8].
• This paper reviews current knowledge of molecular and developmental biology of cinidarians with particular emphasis on tropical scleractinian corals and soft corals from the Great Barrier Reef region [9].

Anatomical context of Anthozoa

• To test whether nuclear translocation of beta-catenin is involved in axial identity and/or germ layer formation in 'pre-bilaterians', we examined the in vivo distribution, stability and function of beta-catenin protein in embryos of the sea anemone Nematostella vectensis (Cnidaria, Anthozoa) [10].

Associations of Anthozoa with chemical compounds

• Three western Atlantic corals, Montastraea annularis, M. faveolata, and M. franksi, typify this controversy; they all spawn sympatrically on the same evenings after the fall full moons [11].
• The ceramics are made resorbable by partially converting the calcium carbonate of corals to form a hydroxyapatite (HA) layer on all surfaces [12].
• Scleractinian corals have long been assumed to be a monophyletic group characterized by the possession of an aragonite skeleton [13].
• CONCLUSION: Calculation of adherence rates using the lower limit of CORALs of indinavir or nelfinavir in children may be a useful measurement for the assessment of nonadherence to antiretroviral therapy in children [14].
• RESULTS: The following CORALS were found: indinavir <0.23 or >3.3; nelfinavir <0.36 or >2.1; ritonavir <0.18 or >1.9; saquinavir <0.28 or >2 [15].

Gene context of Anthozoa

• AAAS annual meeting. Don't sugarcoat corals [16].
• We conclude that most recruitment by corals is very local, particularly in brooders, but that enough propagules are widely dispersed to ensure that both broadcast spawning and brooding species form vast effectively panmictic populations on the Great Barrier Reef [7].
• CAR1 was also associated with non-Acroporid corals of the Caribbean, as well as with two Acroporid corals native to the Pacific. CAR1 was not present in the water column [17].
• Our results, coupled with genetic and demographic data from other reef fishes and corals, provide robust support for the Mona Passage as a long-term biogeographic barrier for Caribbean animals [18].
• The ancestral role of Brachyury: expression of NemBra1 in the basal cnidarian Nematostella vectensis (Anthozoa) [19].

Analytical, diagnostic and therapeutic context of Anthozoa

• This meta-analysis examined 12 species of broadcasting corals at 25 sites spanning 22 degrees of latitude (10 degrees -32 degrees N) from Venezuela to Bermuda in the Atlantic Ocean from 1986 to 2004 [20].
• Nitrogen and photosynthetic function of hermatypic corals. Oxygen exchange of Stylophora pistillata coral under artificial feeding [21].
