Biological activities of marine invertebrates extracts from the northeast brazilian coast

Braz. j. biol; 80 (2), 2020
Abstract This paper reports the in vitro antiproliferative effects, antiprotozoal, anti-herpes and antimicrobial activities of 32 organic extracts of 14 marine sponges and 14 corals collected in northeast Brazilian coast. The ethanolic extracts of the sponges Amphimedon compressa and Tedania ignis, and t...

In Vivo Biological Effects of Marine Biosilica on a Tibial Bone Defect in Rats

Abstract Research on biomaterials of natural origin has gained prominence in the literature. Above all, marine sponges, due to their architecture and structural components, present a promising potential for the engineering of bone tissue. In vitro studies demonstrate that a biosilica of marine sponges ha...

Ecology and biotechnological potential of bacterial community from three marine sponges of the coast of Rio de Janeiro, Brazil

An. acad. bras. ciênc; 89 (4), 2017
ABSTRACT Marine sponges has been a large reservoir of microbial diversity, with the presence of many species specific populations as well as producing biologically active compounds, which has attracted great biotechnological interest. In order to verify the influence of the environment in the composition...

Antibiotic resistance genes detected in the marine sponge Petromica citrina from Brazilian coast

Braz. j. microbiol; 47 (3), 2016
ABSTRACT Although antibiotic-resistant pathogens pose a significant threat to human health, the environmental reservoirs of the resistance determinants are still poorly understood. This study reports the detection of resistance genes (ermB, mecA, mupA, qnrA, qnrB and tetL) to antibiotics among certain cu...

Efectos de extractos de Neopetrosia rosariensis sobre mieloperoxidasa y elastasa con la utilización del modelo neutrófilos
Effects of extracts from Neopetrosia rosariensis on myeloperoxidase and on elastase by using the neutrophil model

Rev. cuba. farm; 48 (1), 2014
Introducción: los neutrófilos son la primera línea de defensa, los cuales liberan su contenido granular, constituido entre otros por enzimas generadoras de especies reactivas del oxígeno como mieloperoxidasa y enzimas proteolíticas como la elastasa, que degradan elastina y colágeno. Objetivo: evalu...

Acidobacteria appear to dominate the microbiome of two sympatric Caribbean Sponges and one Zoanthid

Biol. Res; 47 (), 2014
BACKGROUND: Marine invertebrate-associated microbial communities are interesting examples of complex symbiotic systems and are a potential source of biotechnological products. RESULTS: In this work, pyrosequencing-based assessment from bacterial community structures of sediments, two sponges, and one zoa...

Evaluation of antimicrobial activity and cell viability of Aloe vera sponges

Electron. j. biotechnol; 16 (1), 2013
Background: Aloe vera L., member of the Liliaceae family, has been shown to stimulate cell proliferation and contribute to healing and angiogenesis, has anti-bacterial, anti-fungal and anti-inflammatory activity. In addition, Aloe vera can be used as a support for drug transport. Our objective is to eval...

Bioactivities of extracts from the marine sponge Halichondria panicea

In the present study, we screened the biological activity of extracts from the marine sponge Halichondria panicea collected in the Arabian Sea. Crude toxin was obtained by methanol, chloroform-methanol (2:1) and aqueous extraction. Subsequently, the protein concentration of each crude extract was determi...

Actividades biológicas del extracto acuoso de la esponja Aplysina lacunosa (Porifera: Aplysinidae)

Rev. biol. trop; 54 (supl.3), 2006
Biological activity of an aqueons extract of the sponge Aplysina lacunosa (Porifera: Aplysinidae). The aqueous extract and protein precipitate of Aplysina lacunosa (Pallas, 1776) were studied to assess their hemagglutinating, hemolysing, antibacterial, and antifungal activities. Specimens of the marine s...
