The dermis of sea cucumbers is a catch connective tissue or mutable collagenous tissue that shows large changes in stiffness. Extensive studies on the dermis revealed that it can adopt three different states having different mechanical properties that can be reversibly converted. These are the stiff, standard and soft states. The standard state is readily produced when a dermal piece is immerse...

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 ova...

The sea cucumber (Stichopus vastus) is an underutilized species, as most of its parts, including the integument (high collagen content) are thrown away during processing. The aim of this study was to investigate the effects of different hydrolysis conditions (substrate to enzyme ratio (S/E), reaction temperature, and hydrolysis time) on the angiotensin I converting enzyme (ACE) inhibitory and r...

We have previously characterized the first invertebrate homolog of serum amyloid A (SAA) proteins in the sea cucumber Holothuria glaberrima, where its expression is associated with intestinal regeneration, suggesting a possible involvement of SAA proteins in intestinal morphogenesis. Here we show that bacterial lipopolysaccharides (LPS) trigger a coelomocyte-mediated immune response in H. glabe...

The sea cucumber (Holothuria atra) extracts have been evaluated for the presence of bioactive compounds and various biological activities. The methanol extracts showed anti proliferative activities against the Hela and MCF-7 cell lines. Similarly the inhibitory effects of Herpes simplex virus 1 and 2 cells were detected using the plaque reduction assay. The extracts of H. atra were purified usi...

Arginine kinase plays an important role in the cellular energy metabolism of invertebrates. Dimeric arginine kinase (dAK) is unique in some marine invertebrates. The effects of Zn²(+) on the unfolding and aggregation of dAK from the sea cucumber Stichopus japonicus were investigated. Our results indicated that Zn²(+) caused dAK inactivation accompanied by conformational unfolding, the exposure ...

Modern greenhouses having lighting systems are large consumers of electricity. In Europe alone, the lighting consumption is estimated to 150 TWh per year. High pressure sodium (HPS) lamps are still dominating and the illumination is in general controlled manually by on/o control. Changing to light emitting diodes (LED) gives the possibility of adapting the spectrum (i.e. changing the power spli...

Liquid chromatography-mass spectrometry is one of the most powerful methods for the identification and detection of chemical structures of lipids. In this study, we attempted to identify the chemical structures of glucosylceramides from maize, rice, mushroom (maitake) and sea cucumber by liquid chromatography-ion trap mass spectrometry. For structural analysis of glucosylceramides, [M+H]+, [M+H...

Sea cucumbers are amongst the highest value seafoods available commercially, especially in south-east Asian region, primarily due to their nutritional and health benefits as applied Traditional Chinese Medicine. While majority of studies for products derived from sea cucumber compounds have been conducted vitro , number vivo evidence-based human clinical limited. This review has critically asse...
