Ostreid herpesvirus 1 (OsHV-1), a member of the family (order ), is a major pathogen of bivalves. However, the molecular details of the malacoherpesvirus infection cycle and its overall similarity to the replication of mammalian herpesviruses (family ) remain obscure. Here, to gain insights into the OsHV-1 biology, we performed long-read sequencing of infected blood clams, , which yielded over one million OsHV-1 long reads.

The application of oncolytic peptides has become a powerful approach to induce complete and long-lasting remission in multiple types of carcinomas, as affirmed by the appearance of tumor-associated antigens and adenosine triphosphate (ATP) in large quantities, which jumpstarts the cancer-immunity cycle. However, the ATP breakdown product adenosine is a significant contributor to forming the immunosuppressive tumor microenvironment, which substantially weakens peptide-driven oncolytic immunotherapy. In this study, a lipid-coated micelle (CA@TLM) loaded with a stapled oncolytic peptide (PalAno) and an adenosine 2A receptor (A2AR) inhibitor (CPI-444) is devised to enact tumor-targeted oncolytic immunotherapy and to overcome adenosine-mediated immune suppression simultaneously.

Production of Pacific oysters in China has depended primarily on hatchery produced seeds since 2016, with the successful introduction and development of triploid oysters. However, the seed supply of Pacific oysters is threatened by recurring mass mortality events in recent years.

Three Perkinsus species have been identified in China, and the Manila clam (Ruditapes philippinarum) was the most frequently infected species in northern China. Although the occurrence and seasonal variation of Perkinsus spp.

A3@GMH was prepared using an emulsion template method and its physicochemical properties were characterized. The in vivo and in vitro photothermal conversion abilities of A3@GMH were investigated using an infrared thermal imager.

Initially described as an oyster pathogen, OsHV-1 can infect other bivalve species, like the blood clam Scapharca broughtonii. However, at present, little is known about the molecular interactions during OsHV-1 infection in the blood clam.

In invertebrates, only two herpesviruses are known: the malacoherpesviruses HaHV-1 and OsHV-1 infecting gastropods and bivalves, respectively. To understand viral transcript architecture and diversity we first reconstructed full-length viral genomes of HaHV-1 infecting and OsHV-1 infecting by DNA-seq.

Efforts to study their population genetics, breeding, cultivation, and stock enrichment have been somewhat hindered by the lack of a reference genome. Herein, we report the complete genome sequence of S.

The genome of HaHV-1 has been sequenced, but the functions of the putative genes and their roles during infection are still poorly understood. In the present study, transcriptomic profiles of at 0, 24 and 60 h post injection (hpi) with HaHV-1 were characterized through high-throughput RNA sequencing.

Mass mortalities of ark shell adults related to Ostreid herpesvirus-1 (OsHV-1) infection have occurred frequently since 2012. However, due to the lack of transcriptomic resource of ark shells, the molecular mechanisms underpinning the virus-host interaction remains largely undetermined.

An enzyme immunoassay based on the antibody prepared was developed and applied to detect salbutamol residue spiked in swine liver. An unusual coating antigen, clenbuterol-ovalbumin (OVA) conjugate instead of salbutamol-OVA conjugate, was used in the immunoassay and the results were discussed based on the structures of related compounds.
