New metabolites isolated from soft corals and sponges of the Red Sea are discussed. It is the aim of this report to describe several marine natural products which have recently been isolated and identified by us. The report will include metabolites of sponges and soft corals collected in the straits of the Gulf of Eilat and the Gulf of Suez, The Red Sea(Ref.1). Diterpenoids from Spongia arabica...

Microbial communities associated with marine sponges carry out nutrient transformations essential for benthic-pelagic coupling; however, knowledge about their composition and function is still sparse. We evaluated the richness and diversity of prokaryotic assemblages associated with three high-microbial-abundance (HMA) and three low-microbial-abundance (LMA) sympatric Mediterranean sponges to a...

Sponges have a remarkable capacity to rapidly regenerate in response to wound infliction. In addition, sponges rapidly renew their filter systems (choanocytes) to maintain a healthy population of cells. This study describes the cell kinetics of choanocytes in the encrusting reef sponge Halisarca caerulea during early regeneration (0-8 h) following experimental wound infliction. Subsequently, we...

Background: Surgical site infection (SSI) remains a concern in shoulder surgery, especially during arthroplasty. Whilemany studies have explored the characteristics and efficacy of different sterilizing solutions, no study has evaluated themethod of application. The purpose of this study was to compare two popular pre-surgical preparatory applications (two4 x 4 cm gauze sponges and applicator s...

Mathematical morphology has traditionally been grounded in lattice theory. For non-scalar data lattices often prove too restrictive, however. In this paper we present a more general alternative, sponges, that still allows useful definitions of various properties and concepts from morphological theory. It turns out that some of the existing work on “pseudo-morphology” for non-scalar data can in ...

Here we report on the trophodynamics of the bacteria-containing coral reef sponge Halisarca caerulea. The assimilation and respiration of the 13C-enriched substrates glucose, algal-derived dissolved and particulate organic matter (diatom-DOM and -POM), and bacteria were followed in 1and 6-h incubations. Except for glucose, all substrates were readily processed by the sponge, with assimilation b...
