Morphometric and phylogenetic analysis of a commercial fish (Teleostei, Leiognathidae).

The complete mitochondrial genome and phylogenetic analysis for from the South China Sea was performed using shallow genome skimming. For accurate species identification and redescription, morphometric and meristic characters were examined and compared with previous descriptions. To facilitate the identification of species and to enable comparison with the mitochondrial genome phylogeny, molecular comparisons were conducted using three mitochondrial genes: large ribosomal RNA ( rRNA), cytochrome c oxidase subunit 1 (), and NADH dehydrogenase ().

Carvacrol-loaded emulsions stabilized by soy protein isolate/chitosan oligosaccharide conjugates improved the quality of refrigerated sea bass (Lateolabrax maculatus).

In this study, the soybean protein isolate / chitosan oligosaccharide (SPI/COS) conjugates were developed using glycosylation and used as a stabilizer of carvacrol-loaded emulsions for refrigerating sea bass (Lateolabrax maculatus). The results of Fourier transform infrared spectroscopy and fluorescence spectroscopy showed that COS modified the secondary and tertiary structure of SPI by covalent binding. The SPI/COS conjugate with a mass ratio of SPI and COS of 4:1 (SPI/COS-4) exhibited high glycosylation degree, great water solubility and better emulsification properties.

Chronic heat stress is capable of reducing the growth performance, causing damage to the liver structure, and altering the liver glucose metabolism and lipid metabolism in largemouth bass (Micropterus salmoides L.).

High temperatures cause abnormal energy metabolism and inhibit the growth of fish in aquaculture. However, the mechanism of energy metabolism under chronic heat stress is still unknown. In this study, largemouth bass (Micropterus salmoides, LMB) was treated with 25℃, 29℃, and 33℃ for 8 weeks.

Spatial and temporal variation of nutrient distribution in the Yangtze River estuary and adjacent waters: Insights from GOCI data analysis.

Nutrients are critical in assessing water quality, so understanding their distribution and variability is essential for effective marine environmental protection. This study focuses on the Yangtze River estuary and surrounding waters, where suspended solids show a strong correlation with active phosphates and silicates. Using GOCI imagery and measured nutrient concentrations, such as active phosphate and silicate, remote sensing models were developed to investigate the seasonal and daily changes in surface water nutrients.

Establishment and characterization of a fin cell line from Takifugu obscurus and its application to fish immunology.

Takifugu obscurus (pufferfish) is an important species in aquaculture and has become widely popular in China and Japan. However, the development of the pufferfish aquaculture industry has been significantly impacted by severe diseases. Fish cell lines, as a model for in vitro studies, have the advantages of low cost, easy culture, and low genetic variation rate.

Effects of functionalized nanoplastics on oxidative stress in the mussel Mytilus coruscus.

In the marine environment, various weathering effects on micro or nanoplastics lead to surface modifications, which in turn alter their toxic effects on aquatic organisms. This study investigated the impact of three types of nanoplastics (NPs, NPs-NH, NPs-COOH) on the antioxidant capacity of Mytilus coruscus gills, mantle, and hemolymph over 28 days. Analyzed key antioxidant stress indicators (CAT, SOD, GSH, GSH-Px, MDA, HO) and conducted IBR and PCA analyses to evaluate the toxic effects of modified nanoplastics.

Food-derived umami peptides: bioactive ingredients for enhancing flavor.

In order to provide a further overview of the bioactivities of food-derived umami peptides, the study reviewed the sources, preparation and screening, flavor presentation properties, functional properties and their recent progress in the food industry. Food-derived umami peptides could be extracted and prepared by enzymatic and fermentation techniques. Machine learning, molecular docking technology and peptidomics are efficient methods for screening and identifying umami peptides and exploring their flavor mechanisms.

Enhancing efficiency and control in DNA hydrogel synthesis: A dual rolling circle amplification approach and parameter optimization study.

DNA hydrogels are a focus of current research in the realm of cutting-edge functional biomaterials. Rolling circle amplification (RCA) technology has surfaced as a flexible approach for producing functional DNA hydrogels in a one-pot manner, owing to its effectiveness and ease of use. This study introduces a simple dual RCA approach for producing DNA hydrogels.

Marine anoxia impede the transformation of dissolved organic carbon released by kelp into refractory dissolved organic carbon.

The transformation of dissolved organic carbon (DOC) released by macroalgae into refractory dissolved organic carbon (RDOC) through microbial carbon pump (MCP) represents a crucial carbon sequestration process. This process mainly takes place in coastal areas, where it is likely affected by marine anoxia. The interactions between the components of DOC released by kelp and the community structure of heterotrophic bacteria both under normoxic and anoxic conditions were studied by three-dimensional fluorescence parallel factor analysis (PARAFAC), Fourier Transform-Ion Cyclotron Resonance-Mass Spectrometry (FT-ICR-MS) and 16S rRNA high-throughput sequencing.

Global occurrence, food web transfer, and human health risks of polycyclic aromatic hydrocarbons in biota.

Polycyclic aromatic hydrocarbons (PAHs) are widespread organic pollutants that pose significant health risks due to their bioaccumulation in the biota. This study examines the global distribution of PAHs in biota, identifies key factors influencing using boosted regression tree (BRT) models, analyzes their transfer through trophic magnification factors (TMF), and evaluates health risks using the EPA risk assessment model. Research on PAHs has grown from 1978 to 2023, peaking in 2021, with 171 out of 241 studies (71.

Smaller Formats of Volleyball Lead to Greater Improvements in Lower Limb Strength and Power, As Well As Reductions in Landing Forces: A Randomized Controlled Study in Girls.

The N-terminal polypeptide of a new shell matrix protein hicraqin accelerates the rate of calcium carbonate deposition.

Matrix proteins play important roles in shell formation by regulating the assembly of organic matrix and minerals. Here, we obtained a new matrix protein (hicraqin) from Hyriopsis cumingii. The amino acid sequence of hicraqin contains multiple aggregated (Gly)n (n > 2) residues, a feature unique to silk-like matrix proteins.
