| a computerized tank system for studying the effect of temperature on calcification of reef organisms. | mediated by algal symbionts, calcification in reef building corals is one of the important processes, which enable coral's growth. in the present study, we used a buoyant weighing technique to study calcification of two coralline species, stylophora pistillata and the hydrocoral millepora dichotoma. the colonies were grown in a tank system, in which light, nutrition and water motion were kept constant and temperature was elevated by means of a computerized controlled apparatus. an almost constan ... | 2002 | 11741711 |
| comparative toxinological and immunological studies on the nematocyst venoms of the red sea fire corals millepora dichotoma and m. platyphylla. | a method appropriate for isolating of fire coral nematocysts of millepora dichotoma (md) and millepora platyphylla (mp) was described and compared with techniques that had been used before. isolated nematocyst venoms of md (md-tx) and mp (mp-tx) were lethal to mice (had ld50 values of 0.51 and 0.21 microg/g mouse body, respectively) and displayed variable hemolytic, vasopermeable and dermonecrotic properties. the potent hemolysins of md-tx and mp-tx, which purified by gel filtration chromatograp ... | 2002 | 11912057 |
| milleporin-1, a new phospholipase a2 active protein from the fire coral millepora platyphylla nematocysts. | stings of fire corals, potent hydroids common in the red sea, are known to cause severe pain and they develop burns and itching that lasts few hours after contact. nematocyst venom of millepora platyphylla (mp-tx) was isolated according to a recent method developed in our laboratory to conduct a previous investigation on the nematocyst toxicity of millepora dichotoma and m. platyphylla. in this study, mp-tx was fractionated by using both gel filtration and ion exchange chromatography. simultaneo ... | 2004 | 15683837 |
| interconnected network of ganglion-like neural cell spheres formed on hydrozoan skeleton. | identifying scaffolds supporting in vitro reconstruction of active neuronal tissues in their 3-dimensional (3d) conformation is a major challenge in tissue engineering. we have previously shown that aragonite coral exoskeletons support the development of neuronal tissue from hippocampal neurons and astrocytes. here we show for the first time that the porous aragonite skeleton obtained from bio-fabricated hydrozoan millepora dichotoma supports the spontaneous organization of dissociated hippocamp ... | 2007 | 17518598 |
| isolation and characterization of a novel protein toxin from fire coral. | fire corals (millepora spp.) cause severe pain and inflammatory effects in humans upon contact, and the organs responsible for these effects are called nematocysts. here, we isolated an active cytotoxin of ca. 18 kda (mctx-1) from nematocysts of millepora dichotoma var. tenera. mctx-1 was potently cytotoxic (ec50 value 79 ng/ml) towards l1210 mouse leukemia cells, hemagglutinated a 0.8% suspension of sheep erythrocytes (0.2 microg protein/ml) and was lethal in crayfish (ld50, 106 microg/kg). we ... | 2008 | 17983598 |
| aragonite crystalline matrix as an instructive microenvironment for neural development. | the ability to mimic cell-matrix interactions in a way that closely resembles the natural environment is of a great importance for both basic neuroscience and for fabrication of potent scaffolding materials for nervous tissue engineering. such scaffolding materials should not only facilitate cell attachment but also create a microenvironment that provides essential developmental and survival cues. we previously found that porous aragonite crystalline matrices of marine origin are an adequate and ... | 2008 | 18924122 |
| host-associated speciation in the coral barnacle wanella milleporae (cirripedia: pyrgomatidae) inhabiting the millepora coral. | speciation by host shift is a common phenomenon observed in many symbiotic animals. the symbiont-host interaction is highly dynamic, but it is poorly documented in the marine realm. in the present study, we examined the genetic and morphological differentiation of the coral barnacle wanella milleporae (obligate to fire corals) collected from four different millepora host species in taiwan to investigate the host specificity of this barnacle. phylogenetic analysis of mitochondrial coi gene for 24 ... | 2009 | 19368648 |

| eilatimonas milleporae gen. nov., sp. nov., a marine bacterium isolated from the hydrocoral millepora dichotoma. | a marine bacterial strain, designated md2(t), was isolated from the damaged tissue of a hydrocoral, millepora dichotoma, collected from the coral reef in the northern red sea, gulf of eilat, israel. strain md2(t) was gram-reaction-negative, rod-shaped and motile, and formed small, creamy and opaque colonies, 1-2 mm in diameter, after 3 days incubation on marine agar at 30°c. the novel strain grew well in nutrient broth at 1.5-6 % nacl and at 20-37°c. the major cellular fatty acids were iso-c17 : ... | 2013 | 23002050 |
