The objective of this study is to develop an osteoinductive scaffold which enables the controlled release of bone morphogenetic protein (BMP)-2. A biodegradable gelatin sponge incorporating 50 wt% of btricalcium phosphate (β-TCP) was fabricated to investigate the osteoinduction activity. The sponge prepared had an interconnected pore structure with an average pore size of 200 mm. The in vivo re...

The proteobacterium Alteromonas sp. strain V450 was isolated from the Atlantic deep-sea sponge Leiodermatium sp. Here, we report the draft genome sequence of this strain, with a genome size of approx. 4.39 Mb and a G+C content of 44.01%. The results will aid deep-sea microbial ecology, evolution, and sponge-microbe association studies.

Many marine sponges are populated by dense and taxonomically diverse microbial consortia. We employed a metagenomics approach to unravel the differences in the functional gene repertoire among three Mediterranean sponge species, Petrosia ficiformis, Sarcotragus foetidus, Aplysina aerophoba and seawater. Different signatures were observed between sponge and seawater metagenomes with regard to mi...

The coral-killing sponge, Terpios hoshinota, has great potential to cover corals and threaten coral reefs. This sponge numerous endosymbiotic cyanobacterial cells, silicate spicules in the tissue, particles on tissue surface, which could have an important role growth defense of sponge. However, little is known about morphological traits these components. Here we report estimated density measure...

Background The aim of our study was to test the long-term efficacy of Endo-SPONGE® therapy in a group of patients treated in our center with vacuum-assisted therapy because of anastomotic leakages after colorectal surgery. Methods Eleven patients [male: 6; mean age: 71 (range: 44-82) years] who had anastomotic leakage treated with Endo-SPONGE® placement were included in the study. Patient rec...

The boring sponge Cliona celata is a nuisance species that can have deleterious effects on eastern oyster Crassostrea virginica growth, condition, and survival. Surprisingly, however, these effects have not been well documented and when examined, results have been equi-vocal. In this study, we provide a direct comparison of growth, condition, and survival of sponge-colonized and uncolonized oys...

A TiO2 film having "photonic sponge" architecture (ps-TiO2) has been prepared using titania Degussa P25 nanoparticles that have been infiltrated into a template obtained through the arrangement of a mixture of different size latex spheres. The resulting photonic sponge exhibits 3.3 fold higher initial photocatalytic degradation rate for succinonitrile disappearance than analogous films of the s...

The selection of a suitable scaffold matrix is critical for cell-based bone tissue engineering. This study aimed to identify and characterize natural marine sponges as potential bioscaffolds for osteogenesis. Callyspongiidae marine sponge samples were collected from the Fremantle coast of Western Australia. The sponge structure was assessed using scanning electron microscopy (SEM) and Hematoxyl...

Sponge diseases have been widely reported, yet the causal factors and major pathogenic microbes remain elusive. In this study, two individuals of the sponge Crella cyathophora in total that showed similar disease-like characteristics were collected from two different locations along the Red Sea coast separated by more than 30 kilometers. The disease-like parts of the two individuals were both c...

new forms of vanadium oxide nanoporous were fabricated using a simple chemical synthesis method. vanadium pentoxide (v2o5) nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. the samples were characterized by high resolution transmission electron microscopy (hrtem), field effect scanning electron microscopy (fesem) and x-ray diffraction (xrd), four...
