Complete mitochondrial genome and phylogenetic analysis of (Annelida, Polychaeta, Cirratulidae) from Weihai, Shandong, China.

species usually inhabit intertidal zones and deep-sea sediments. Their accurate identification has proven to be challenging. Here, we present the complete mitochondrial genome of one Montagu 1808 specimen collected from China.

Acute toxic effects of thiamethoxam on Chinese mitten crab Eriocheir sinensis.

The information about toxic effects of thiamethoxam on non-target aquatic organisms is still incomplete. The semi-static toxicity test method was used to investigate the acute toxic effects of thiamethoxam on Eriocheir sinensis. The results showed that the median lethal concentration (LC50) of thiamethoxam to E.

Antibacterial Activity and Mechanism of the Gallnut Water Extract against Vibrio parahaemolyticus.

Vibrio parahaemolyticus is an important pathogen causing pandemic diseases in marine animals and brings about severe economic losses in aquaculture worldwide. The emergence of multi-drug-resistant V. parahaemolyticus and the prohibition of antibiotics both require the development of new therapeutic agents with alternative action.

Effects of glycosaminoglycan from Urechis unicinctus on the P2Y1 receptor pathway and expression of related factors in rat platelets.

The aim of this study was to examine the effects of glycosaminoglycan (GAG) from Urechis unicinctus on the P2Y1 receptor pathway and expression of related factors in rat platelets. The concentration of calcium ion (Ca) in rat platelets was determined by double wavelength Fura-2 fluorescence spectrophotometry, and the concentrations of inositol trisphosphate (IP) and glycoprotein IIb/IIIa (GPIIb/IIIa) in rat platelets were measured using the enzymatic immunoassay method. The phosphorylation levels of phospholipase C (PLC), phospholipase A (PLA), protein kinase C (PKC), and p38 mitogen-activated protein kinase (p38MAPK) were also detected by Western blot.

Effects of Glycosaminoglycan from Urechis unicinctus on ADP-Induced Platelet Calcium and Membrane Glycoprotein Expressions in Rats.

Background: Previous studies had shown that glycosaminoglycan (GAG) from Urechis unicinctus exerts an obvious antiplatelet aggregation effect.

Objective: This study aims to investigate the effects of GAG from Urechis unicinctus on ADP-induced platelet calcium and membrane glycoprotein expressions in rats.

Methods: Fura-2/AM fluorescence probe was used to measure intracytosolic free-calcium concentration ([Ca2+]i) of platelets and calculate platelet calcium influx and release concentrations.

Effects of glycosaminoglycan from Mactra veneriformis on the protein C system and expression of relevant factors in human umbilical vein endothelial cells.

The aim of this study was to examine whether glycosaminoglycan (GAG) from Mactra veneriformis had an impact on the protein C (PC) system in rats and expression of relevant factors in human umbilical vein endothelial cells. Isotonic saline, heparin sodium (4 mg/kg), and GAG (1, 4, and 16 mg/kg) were administered to Wistar rats through caudal vein at the total volume of 0.5 ml for each injection, and the anticoagulant blood was prepared.

Hypoglycemic effects of glycosaminoglycan from Urechis unicinctus in diabetic mice.

To further utilize glycosaminoglycan from Urechis unicinctus, the hypoglycemic effect and possible mechanism of glycosaminoglycan on diabetic mice were evaluated. Diabetes was induced in mice by intraperitoneal injections of streptozotocin for 3 consecutive days and fed with high-sugar and high-lipid fodder. After diabetes was confirmed, the hypoglycemic effect of glycosaminoglycan from U.

The complete mitochondrial genome sequence of A. stenotaeniatus is 16,594 bp in length and comprises 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region.

Mitochondrial genome of Onychostoma macrolepis (Osteichthyes: Cyprinidae).

Onychostoma macrolepis, which belongs to the genus Onychostoma (Cypriniformes, Cyprinidae), is a benthopelagic fish that inhabits the flowing freshwaters in China. The complete mitochondrial genome sequence of O. macrolepis is 16,595 bp in length and comprises 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 1 control region.

The preliminary study on the antithrombotic mechanism of glycosaminoglycan from mactra veneriformis.

The effect of glycosaminoglycan from Mactra veneriformis on deep venous thrombosis of rats was observed, and the preliminary antithrombotic mechanism of glycosaminoglycan was explained. The results showed that when the glycosaminoglycan was injected intravenously into rats within the dose range of 0.0313-1 mg/kg, the antithrombotic effect increased as the dose increased.
