Previous work on wound healing in holothurians (sea cucumbers) has been concerned with the relatively longterm cellular processes of wound closure and regeneration of new tissue. In this report, we characterize a short-term adhesion that is a very early step in holothurian wound healing. Dissected pieces of dermis from the sea cucumber Parastichopus parvimensis adhered to each other after only ...

OBJECTIVES Marine organisms are known as a potential source of natural products, which contain bioactive substances with therapeutic properties. Sea cucumbers are prominent among marine organisms because of their dietary and therapeutic applications. In addition, they have capacity of synthesizing saponins molecules and other metabolites with therapeutic properties such as antitumor, antimicrob...

Small-scale fisheries are important to livelihoods and subsistence seafood consumption of millions of fishers. Sea cucumbers are fished worldwide for export to Asia, yet few studies have assessed factors affecting socioeconomics and wellbeing among fishers. We interviewed 476 men and women sea cucumber fishers at multiple villages within multiple locations in Fiji, Kiribati, Tonga and New Caled...

Market preferences of natural resources contribute to shape their exploitation and production. Beche-de-mer, the product after gutting, cooking, salting and drying sea cucumbers, is exported worldwide to Asian dried seafood markets. A better understanding of the trade, value and market preferences of Pacific island beche-de-mer could identify critical postharvest processing techniques and manag...

Sea cucumbers saponins are triterpenoid glycosides which exert beneficial biomedical effects. This study was performed to assess the effect of saponin extracted from sea cucumber Holothuria leucospilota (H. leucospilota) on maturation of mice oocytes and granulosa cells. The germinal vesicles oocytes were collected from 6-8 weeks old Naval Medical Research Institute (NMRI) mice ovaries, randoml...

Understanding of the echinoderm nervous system is limited due to its distinct organization in comparison to other animal phyla and by the difficulty in accessing it. The transparent and accessible, apodid sea cucumber Leptosynapta clarki provides novel opportunities for detailed characterization of echinoderm neural systems. The present study used immunohistochemistry against FMRFamide and hist...

The intestinal bacterial diversity of Stichopus japonicus was investigated using 16S ribosomal RNA gene (rDNA) clone library and Polymerase Chain Reaction/Denaturing Gradient Gel Electrophoresis (PCR-DGGE). The clone library yielded a total of 188 clones, and these were sequenced and classified into 106 operational taxonomic units (OTUs) with sequence similarity ranging from 88 to 100%. The cov...

Sea cucumber Stichopus monotuberculatus is one species of tropical sea cucumbers with high recognition and economic value. While advances have been made in the nursery rearing cucumber, influence environmental factors on its locomotion behavior remains less understood, which restricts establishment mariculture technologies. In present study, S. under different temperatures flow velocities were ...

background: the present study aimed to survey antileishmanial activity of methanolic holothuria leucospilota extract against leishmania major promastigotes in vitro. methods: promastigotes were cultured in rpmi 1640 and after reaching the stationary phase, the study was conducted with different concentrations of the extract. afterwards, mtt colorimetric assay for the obtaining of 50% inhibitory...
