Ultra-selective desulfurization of 4, 6-dimethyldibenzothiophene via carbon-sulfur bond cleavage with the bimetal single atom on N-rGO.

A single-atom Cu and Ni anchored on N-doped Reduced Graphene Oxides, which confer the intensified exposure of interior active sites, was developed. Due to single-atom active sites which accelerated the oxygenation and hydrogenation, the prepared Cu/Ni-N-rGO shows excellent conversion, good stability and selectivity for CS bond cleavage by catalytic oxidation and hydrogenation at the different temperatures. The desulfurization ratio and selectivity for 4, 6-DMDBT to carbonhydrogen were 100 % and 100 %, respectively, on the suitable conditions.

The Penaeus stylirostris densovirus capsid protein interacts with the Litopenaeus vannamei BCCIP protein.

Viral capsid proteins play an important role in the viral infection process. To identify the cellular proteins in shrimp that interact with the Penaeus stylirostris densovirus capsid protein (PstDNV-CP), we constructed a yeast two-hybrid (Y2H) cDNA library of the muscle tissue of Litopenaeus vannamei, and hybridized the bait vector pGBKT7-CP with this library. Cloning and sequencing showed that the shrimp protein interacting with PstDNV-CP was a homolog of BRCA2 and CDKN1A(p21)-interacting protein (BCCIP).

Transcriptome analysis of Litopenaeus vannamei in response to white spot syndrome virus infection.

Pacific white shrimp (Litopenaeus vannamei) is the most extensively farmed crustacean species in the world. White spot syndrome virus (WSSV) is one of the major pathogens in the cultured shrimp. However, the molecular mechanisms of the host-virus interaction remain largely unknown.

Transcriptome analysis of Pacific white shrimp (Litopenaeus vannamei) hepatopancreas in response to Taura syndrome Virus (TSV) experimental infection.

Background: The Pacific white shrimp, Litopenaeus vannamei, is a worldwide cultured crustacean species with important commercial value. Over the last two decades, Taura syndrome virus (TSV) has seriously threatened the shrimp aquaculture industry in the Western Hemisphere. To better understand the interaction between shrimp immune and TSV, we performed a transcriptome analysis in the hepatopancreas of L.

[Molecular cloning of Litopenaeus vannamei TCP-1-eta gene and analysis on its relationship with cold tolerance].

To study the molecular mechanism of cold tolerance, we cloned TCP-1-eta homolog gene from Litopenaeus vannamei and studied its relationship with cold tolerance. Based on the sequence from electronic cloning, a pair of primers were designed, and a 1 705 bp cDNA was obtained by RT-PCR. The cDNA contains 1 629 bp ORF, which encodes a peptide of 542 aa.
