The analysis of complete genome sequence and comparative genomics of Vibrio parahaemolyticus LF1113 in Hainan.

Vibrio parahaemolyticus is a Gram-negative, halophilic and polymorphic coccobacillus. It is world-widely distributed and has resulted in great economic losses since its first appearance. In this study, a pathogenic strain was isolated from diseased pearl gentian grouper and identified as V.

Genome-wide association study reveals genomic loci of sex differentiation and gonadal development in .

, a commercially significant marine fish, is primarily found in the Western Pacific regions and along the coast of Southeast Asia. A thorough analysis of the molecular mechanisms involved in sex differentiation is crucial for gaining a comprehensive understanding of gonadal development and improving sex control breeding. However, the relevant fundamental studies of are relatively lacking.

Interfacial Bonding and Fracture Behaviors of AZ63 Magnesium Alloy Sheet Processed by Accumulative Roll Bonding.

In order to understand the strengthening and the failure mechanism of accumulative roll bonding (ARB)-processed AZ63 Mg alloy, the interfacial bonding and fracture behavior of an ARB-processed AZ63 sheet were studied through electron microscopic analysis. The correlation between the mechanical properties, the microstructure, and the ARB processing parameters of an AZ63 sheet were presented. The experimental results have demonstrated that the average grain size of AZ63 Mg alloy processed by ARB was remarkably refined from 12.

Research Progress of Alumina-Forming Austenitic Stainless Steels: A Review.

The development of Alumina-Forming Austenitic (AFA) stainless steel is reviewed in this paper. As a new type of heat-resistant steel, AFA steel forms an alumina protective scale instead of chromia in a corrosive environment. This work summarizes the types of developed AFA steels and introduces the methods of composition design.

Influence of the Anisotropy on the Microstructure and Mechanical Properties of Ti/Al Laminated Composites.

Anisotropy is the difference in the microstructure or mechanical properties of materials in different directions. Anisotropic behavior occurs in rolled sheets, and this anisotropy is very obvious in laminated composites. In this work, the influence of anisotropy on the microstructure and mechanical properties of Ti/Al laminated composites fabricated by rolling was investigated.

Complete chloroplast genome of green alga (J.Agardh) Collins, 1909.

The complete chloroplast (cp) genome of was first assembled and characterized using Illumina pair-end sequencing from the South China Sea. It is 133,626 bp long, with a GC content of 32.94%.

Complete chloroplast genome of green alga (Forsskål) J.Agardh, 1837.

The complete chloroplast genome of from South China Sea has been assembled and characterized for the first time. The circular chloroplast genome was 177,848 bp in length, with a GC content of 33.80%.

Complete chloroplast genome of red seaweed (J. Agardh, 1885).

In this study, we first assembled and characterized the complete chloroplast genome of red seaweed It is 190,431 bp in length, with an AT content of 70.56%. In total, 122 genes were identified, and they consisted of 87 protein-coding genes, 33 tRNA genes, and two rRNA genes.

Forming Limit Stress Diagram Prediction of Pure Titanium Sheet Based on GTN Model.

In this paper, the initial values of damage parameters in the Gurson-Tvergaard-Needleman (GTN) model are determined by a microscopic test combined with empirical formulas, and the final accurate values are determined by finite element reverse calibration. The original void volume fraction (), the volume fraction of potential nucleated voids (), the critical void volume fraction (), the void volume fraction at the final failure () of material are assigned as 0.006, 0.

A new flavonoid derivative and a new 5-hydroxyanthranilic acid derivative from the sea urchin-derived sp. HDa1.

One new flavonoid derivative flavoside A (), one new 5-hydroxyanthranilic acid derivative crassilin (), along with the known angucyclinone PD116740 () and oxachelin (), was isolated from the EtOAc extract of the fermentation broth of the sea urchin ()-derived actinobacterium, sp. HD01. The structures of these compounds were established on the basis of their HR-ESI-MS and NMR spectroscopic data.

Anthocidins A⁻D, New 5-Hydroxyanthranilic Acid Related Metabolites from the Sea Urchin-Associated Actinobacterium, Streptomyces sp. HDa1.

Four new 5-hydroxyanthranilic acid related compounds, named anthocidins A⁻D (⁻), two known analogues -lauryl 5-hydroxyanthranilate () and isolauryl 5-hydroxyanthranilate (), together with benzamide (), 3-hydroxy-4-methoxycinnamamide (), and (3-)-hexahydro-3-[(3,4-dihydroxyphenyl)methyl]pyrrolo[1,2-]pyrazine-1,4-dione (), were isolated from the fermentation broth of the marine-derived actinomycete, sp. HDa1, which was isolated from the gut of a sea urchin, , collected from Hainan Island, China. The structures of these secondary metabolites were elucidated on the basis of their 1D and 2D-NMR and mass spectroscopic data, and anthocidin A was confirmed by single-crystal X-ray diffraction with Cu Kα radiation.
