Pattern recognition proteins function in innate immune responses by binding to molecules on the surface of invading pathogens and initiating host defense reactions. To explore the role of vitellogenin (Vg) in fish innate immunity, we purified Vg from Carp by gel filtration combined with diethylaminoethyl (DEAE) chromatography. The purified Vg was confirmed(More)
Two sulfated triterpene glycosides, holothurin A(1) (HA(1)) and 24-dehydroechinoside A (DHEA), isolated from the sea cucumber Pearsonothuria graeffei, are of the holostane type with 18(20)-lactone and identical carbohydrate chains. DHEA has a side chain 23 (24)-double bond, while HA(1) has a hydroxyl group at C-21. In this study, we compared the effects of(More)
BACKGROUND Echinoside A (EA) and ds-echinoside A (DSEA) are triterpene glycosides isolated from the sea cucumber Pearsonothuria graeffei. DSEA, the desulfurisation product of EA, has the following structure: β-D-xylopyranosyl-holost-8(9),11(12)-diene-3β,17α-diol. In the present study, we examined the anti-tumour activities-in particular, the(More)
Endovascular embolization has become an important treatment option for cerebral aneurysms, along with surgical clipping. But few literatures mentioned infectious complications after coiling of aneurysms. We present a patient with a brain abscess that developed after endosaccular embolization of a left middle cerebral artery aneurysm. The brain abscess was(More)
A low molecular weight sulfated polysaccharide (L-A) was prepared bymild acid hydrolysis of crude fucoidan (F-A) from Laminaria japonica. In comparison with F-A, L-A had a lower proportion of fucose residues,but a similar proportion of sulfate. The galactose content of both fractionswas relatively high, especially for L-A (57%). The antioxidant propertiesof(More)
This study investigated the effects of a combination of fucosylated chondroitin sulfate (CHS) and rosiglitazone (RSG) on glucose metabolism in the liver of insulin-resistant C57BL/6J mice fed a high-fat high-sucrose diet for 19 weeks. The results showed that the combination (CHS/RSG) synergistically improved body weight gain, liver weight, fasting blood(More)
Nonalcoholic fatty liver disease is the most common chronic liver disease in the world, and is becoming increasingly prevalent. Saponins of sea cucumber (SSC) are proven to exhibit various biological activities. Therefore, the present study was undertaken to examine the effect of saponins extracted from sea cucumber (Pearsonothuria graeffei) on the(More)
Antarctic krill (Euphausia superba) has been widely studied and extensively recognized as a target for commercial fishing. In this study, Antarctic krill chitin was extracted from defatted Antarctic krill shell, and its crystalline structure and thermal properties were characterized by employing Fourier transform infrared spectroscopy, X-ray diffractometry,(More)
This study investigated the effects of fucosylated chondroitin sulfate (CHS) isolated from sea cucumber on glucose metabolism and insulin signaling in the liver of insulin-resistant C57BL/6 mice fed a high-fat, high-sucrose diet (HFSD). Male C57BL/6J mice were randomly assigned into six groups: control; HFSD; 1 mg RSG/kg·body weight (RSG); 80 mg CHS/kg ·(More)
A novel glycosaminoglycan-like sulfated polysaccharide (AAP) from the pleopods of Haliotis discus hannai Ino was purified by DEAE ion exchange chromatography followed with S-300 HR geltrion chromatography. Chemical composition analysis indicated that AAP was composed of galactosamine, glucuronic acid, fucose, galactose with a ratio of 2.14:2.37:2.94:1, the(More)
