This study aims to estimate anthropogenic sources of pollutants such as heavy metals that pollute or poison the commercial marine finfish and shellfish present around the Ennore coastal area and to identify, quantify and manage the associated risks for the betterment of society. The levels of toxic heavy metal concentrations from monitoring and surveillance of copper, chromium, cadmium, mercury, lead and zinc heavy metals were estimated from water, sediment and commercial marine finfish and shellfish samples that were collected for study. The individual mean bioaccumulation index (IMBI) and Metal Pollution Index (MPI) values varied between finfish and shellfish. Target hazard quotient (THQ) index values were calculated, and copper and zinc were found to be elevated at levels affecting children in particular. Thus, efforts are urgently needed to resolve the current and potential risks associated with the negative impact of heavy metal intake from seafood on human health. This study attempts to identify levels of metal contamination and corresponding risk factors with regard to human health.

Tumor necrosis factor receptor-associated factor 2 (TRAF2) is a key adaptor molecule in tumor necrosis factor receptor signaling complexes, facilitating downstream immune-related signaling cascades. This study aimed to elucidate its function in teleost fish by characterizing the TRAF2 homolog of the red-spotted grouper (Epinephelus akaara, EaTraf2). The open reading frame of EaTraf2 encodes a putative protein of 520 amino acids, containing several characteristic domains of TRAF2.

Trimethylamine oxide (TMAO), a microbial metabolite commonly found in foods, has been attracting increasing attention as it is associated with the risk of several diseases. Simple and accurate analytical methods are crucial for TMAO study. In the present study, we proposed a chemical reaction-based fluorescence assay for TMAO detection using synthetic small molecular probes.

Evolution and expression of TLR5a and TLR5b in lamprey (Lampetra japonica).

College of Life Sciences, Liaoning Normal University, Dalian, China; Lamprey Research Center, Liaoning Normal University, Dalian, China. Electronic address:

The lamprey serves as a key model organism for studying the origin and evolution of species, embryonic development, and the immune system. The immune system primarily relies on pattern recognition receptors, including Toll-like receptors (TLRs), with Toll-like receptor 5 (TLR5) having a particularly complex evolutionary history. Currently, although TLR5 is being identified in an expanding array of taxonomic groups, a comprehensive study on its evolutionary aspects is yet to be conducted.

Article Synopsis
  • Cronobacter species are opportunistic pathogens found in various foods, making their isolation from seafood, like fish and shellfish, challenging due to their coexistence with similar bacteria in aquatic environments.
  • This study analyzed 75 seafood samples from retail markets, revealing a 32% incidence rate of Cronobacter, with dried fish showing the highest prevalence (48%).
  • The best method for isolating Cronobacter spp. involved using specific enrichment broths and isolation media, emphasizing dried fish's role as a significant reservoir for the pathogen, particularly C. sakazakii.
