Deposition characteristics of microplastics in coral reef fish with different feeding habits from the Xisha Islands Waters, South China Sea.

Over the past decade, awareness of plastic pollution has significantly increased, leading to a focus on its potential adverse effects on biota, including the ingestion of microplastics by fish. This study investigates the abundance, composition, and characteristics of microplastics in the gills and gastrointestinal tracts (GITs) of 96 coral reef fish with different feeding habits (herbivorous fish: Scarus rivulatus, Naso lituratus, and Acanthurus triostegus; omnivorous fish: Abudefduf vaigensis; carnivorous fish: Epinephelus merra) from the Xisha Islands Waters, South China Sea. The relationships between microplastic abundance and fish length, weight, and feeding habits were also analyzed.

Population genetics of (Cephalopoda: Ommastrephidae) in the northwest Pacific Ocean via GBS sequencing.

The common squid, , is an important commercial species that inhabits the northwest Pacific Ocean, particularly the East Japan Sea, the Pacific coast of Japan, and the East China Sea. In this study, we chose 29 individuals from three areas: one type from the Sea of Japan and two types from the East China Sea. A total of 43,529 SNPs were obtained using genotyping-by-sequencing (GBS).

Microplastic pollution is a widespread concern in the global marine environment. In this study, microplastic pollution status in Xisha waters was investigated. Microplastics were found in all seawater samples, and 90.

Study on the Geographic Variation and Trophic Variation of in Different Areas Based on Stable Isotope Information from the Gladius.

The Japanese flying squid () is an important cephalopod in the northwest Pacific Ocean. In this study, the proostracum of the gladius of samples collected by Chinese squid fishing vessels in the East China Sea and the Sea of Japan in August and December 2018 were continuously cut, and stable isotope values of the cut fragments were used to analyze the migration path and feeding ecology of . The results showed that when the proostracum grew to 120 mm from the distal end, began to migrate.

[Statolith microstructure and growth characteristics of in the northwest Indian Ocean].

Statolith is one of the most important hard tissues to study the age, growth, population structure and life history of cephalopods. In order to stuty statolith microstructure and growth characteristics of in the northwest Indian Ocean, 1009 samples were collected by Chinese light falling-net fishery fleets during investigation and production in the northwest Indian Ocean from February to May of 2019. Total statolith length (TSL), lateral dome length (LDL), wing length (WL) and maximum width (MW) were taken as the indicators of morphological feature of the statolith, combined with the age data, the statolith microstructure and growth characteristics of were studied.

Circ_0045714/miR-331-3p interaction affects IL-1β-evoked human articular chondrocyte injury through regulating PIK3R3 in a ceRNA regulatory cascade.

Background: Osteoarthritis (OA) is characterized by joint pain and joint function limitation. Hsa_circ_0045714 (circ_0045714) is a novel OA-related circular RNA. However, its repertoire remains to be further clarified in joint chondrocytes.

[Factors influencing beak morphology of in the northwest Indian Ocean].

With 1009 samples collected by Chinese light falling-net fishery during February to May in the northwest Indian Ocean, we analyzed the influencing factors of the morphology change of the beak. There were significant differences in the morphologic growth between genders, different gonad maturity stages, and different mantle length. The increment of characteristic parameters growth peaked in the mantle length between 201 and 250 mm, and in the Ⅱ and Ⅲ stages of gonad maturity for females and males, respectively.

[Beak morphological growth characteristic of Gonatopsis borealis in the Northwestern Pacific Ocean].

Beak is one of the most hard tissues in cephalopods, which is important in the study of fishery ecology. We analyzed the morphological growth characteristics of 268 beaks of Gonatopsis borealis collected in the Northwest Pacific Ocean from September to November of 2018 by Chinese jigging fishing fleets. Results from the principal component analysis showed that the upper hood length (UHL), upper crest length (UCL), upper rostrum length (URL), lower hood length (LHL), lower crest length (LCL) and lower rostrum length (LRL) could be used as the morphological characteristic parameters to study the morphological growth of beak.

[Element composition in the statoliths of Sthenoteuthis oualaniensis squid in Xisha islands waters of South China Sea].

Sthenoteuthis oualaniensis is the most important cephalopods fishery resource of the South China Sea, which supported the falling-net fishery of Guangdong, Guangxi and Hainan Provinces of China. Understanding the fisheries biology is essential for sustainable exploitation and management of this squid. Statolith is one of the most important hard tissues of cephalopods which were widely used in the research of fisheries biology and ecology.

The Effect of ADAM8 on the Proliferation and Apoptosis of Hepatocytes and Hepatoma Carcinoma Cells.

This study was undertaken to evaluate the effect of ADAM8 on the proliferation and apoptosis of hepatocytes and hepatoma carcinoma cells during hepatocellular carcinoma (HCC) progression. The expression of ADAM8 was significantly increased with good correlation of PCNA expression increasing and cells apoptosis decreasing during the progression of HCC in the liver of mice. Proliferation experiment in vitro showed that recombinant ADAM8 could induce the expression of PCNA in L02 cells, but not in HepG2 cells.

The Protective Roles of IL-6 Trans-Signaling Regulated by ADAM9 on the Liver in Carbon Tetrachloride-Induced Liver Injury in Mice.

Our study was undertaken to evaluate the important role that a disintegrin and metalloproteinase 9 (ADAM9) regulates IL-6 trans-signaling in carbon tetrachloride (CCl4)-induced liver injury in mice. Mice were divided into four groups. Each group respectively received mineral oil injection, CCl4 injection, anti-ADAM9 monoclonal antibody (mAb) pretreatment and CCl4 injection, anti-ADAM9 mAb and recombinant mouse ADAM9 molecules pretreatment with CCl4 injection.

IL-6 trans-signaling plays important protective roles in acute liver injury induced by acetaminophen in mice.

Our study was undertaken to evaluate the important role of interleukin-6 (IL-6) trans-signaling in acetaminophen (AAP)-induced liver injury. A soluble gp130 protein (sgp130Fc) exclusively inhibits IL-6 trans-signaling, whereas an IL-6/soluble IL-6 receptor (sIL-6R) fusion protein (hyper-IL-6) mimics IL-6 trans-signaling. Using these tools, we investigated the role of IL-6 trans-signaling in AAP-induced liver injury.

[Trace elements in the statoliths of neon flying squid, Ommastrephes bartramii in the Northwest Pacific Ocean].

Statolith is one of the most important hard tissues of cephalopods which is widely used in the research of fisheries ecology including population structure, life history reconstruction and so on. Trace elements of 18 statoliths of neon flying squid Ommastrephes bartramii collected in the Northwest Pacific Ocean in 2007 by Chinese jigging fishing fleets were analyzed by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The results indicated that the statoliths of O.

[Stock assessment and management for Illex argentinus in Southwest Atlantic Ocean based on Bayesian Schaefer model].

Abstract: Bayesian Schaefer model was applied to assess the stock of Illex argentinus in the Southwest Atlantic Ocean, with the risk of alternative management strategies for the squid analyzed. Under the scenarios of normal and uniform prior assumptions, the estimated model parameters and reference points were similar, and higher than the values under the scenario of logarithmic normal prior assumption. Under the three proposed scenarios, the fishing mortalities and the total catches in 2001-2010 were lower than the reference point F0.
