Summary: The study investigated the structure and stability characteristics of oyster ferritin by adding Fe2+ to it. The results showed that the protein structure of ferritin remained largely unchanged after adding Fe2+ and the sample with 1000 Fe2+ exhibited good stability under storage and high temperature conditions.

Summary: This study investigates the IgE sensitisation profiles of patients with oyster allergy to raw and heated Pacific oyster extract. Tropomyosin is identified as the major allergen responsible for oyster allergy, and the study also reveals partial cross-reactivity and/or co-sensitisation between oyster, prawn, and dust mite allergens. This research emphasizes the importance of using recombinant tropomyosin in improved diagnostics and immunotherapy.

Summary: This study investigated the effect of gelatin on the formation of oyster protein gel and the interaction mechanism between gelatin and oyster protein. The results showed that gelatin improved the texture properties of oyster protein gel and enhanced the gelation process. In addition, new hydrogen bonds and beta-sheets structures were formed between gelatin and oyster protein.

Summary: The study reveals that Pacific oysters have a certain sensitivity to paralytic shellfish toxins, with a micromolar range of sensitivity to saxitoxin but less sensitivity to tetrodotoxin. Oysters can be categorized into STX-resistant and STX-sensitive groups regardless of the diet they consume. Additionally, the study highlights the potential of cerebrovisceral nerves of Pacific oysters for electrophysiological and pharmacological studies and demonstrates that the STX sensitivity of oyster nerves can decrease upon exposure to dinoflagellates.

Summary: Ferroptosis is a form of cell death in vertebrates that is dependent on iron and oxidation, typically mediated by redox-related molecules. In this study, homologues of glutathione peroxidase 4 (GPX4) and solute carrier family 7 member 11 (SLC7A11, xCT) were identified from the oyster Crassostrea gigas (designated as CgGPX4 and CgxCT). The mRNA transcripts of CgGPX4 and CgxCT were found in various tissues, with the highest expression in the haemocytes. Treatment with erastin induced ferroptosis in oyster haemocytes, as evidenced by cell malformation, cell death, mitochondrial atrophy, and changes in gene expression.

Summary: Pacific oysters have high nutritional value and various bioactive components, including proteins, glycogen, minerals, and fatty acids. The bioactive components exhibit antimicrobial, antioxidant, and anti-inflammatory effects. However, most studies on the bioactivity of Pacific oysters are conducted in vitro.

Summary: This study investigates the ingestion and egestion of polystyrene microplastics by Pacific oysters and finds that smaller microplastics have higher ingestion and egestion rates. It also suggests that depuration can reduce the potential risk of microplastics to human health from the intake of maricultural products.

Summary: This study compared intertidal oysters with subtidal oysters and found that intertidal oysters at different depths delayed the onset of mortality associated with POMS. Despite slower growth, intertidal oysters showed increased resistance through metabolic, inflammatory, and immune responses, improving their overall health.

Summary: Recent findings show that Wnt signaling plays an important role in regulating the differentiation and proliferation of immune cells. In this study, a Wnt-1 homolog (CgWnt-1) was identified from oyster Crassostrea gigas, and its mRNA expression was found to be significantly up-regulated during the later stages of embryonic development. CgWnt-1 was highly expressed in the mantle of adult oyster. After stimulation with Vibrio splendidus, the mRNA expression levels of CgWnt-1 and Cg8-catenin in haemocytes were significantly increased. Injection of recombinant protein (rCgWnt-1) into oyster resulted in the up-regulation of cell proliferation related genes and an increase in the percentage of proliferating cells in haemocytes. The inhibitory effect of the Wnt signal inhibitor C59 on these responses was also demonstrated. These results indicate that CgWnt-1 plays a role in modulating haemocyte proliferation and immune response in oysters.

Summary: This study found that the coupling between benthic and pelagic habitats in the Eastern English Channel is a permanent feature, potentially favored by shallow depth and driven by two trophic processes. Resource partitioning and the presence of generalist species allow fish to fully utilize available resources, maintaining the coupling between benthic and pelagic habitats.

Summary: The study examined a dataset of marine microphytoplankton collected from 2003 to 2014, revealing significant changes in the community structure during this period. It was found that temporal changes were more pronounced than spatial differences, with variations in water temperature and freshwater depth playing a role in shaping the community structure. Additionally, five specific taxonomic units were identified as playing a key role in these community changes. This study highlights the importance of understanding phytoplankton species ecological niches and considering biotic interactions in order to fully grasp the processes influencing plankton communities and diversity patterns.

Summary: Efficient implementation of ecosystem-based fisheries management largely depends on data availability, with this study demonstrating that fish diet sampling can provide valuable information on the spatial distribution of benthic organisms. The spatial distributions of invertebrates found in fish digestive tracts showed significant overlap with dedicated benthos surveys, particularly for Galatheidae. This suggests that fish could potentially serve as suitable biological samplers for monitoring benthic invertebrates.

Summary: Stable isotope mixing models are used to reconstruct animal diet, but current research neglects the dynamics of isotopic ratios and the impact of time lag on diet reconstruction. By using a dynamic mixing model, it is possible to more accurately estimate the consumer's diet and avoid misinterpretation in ecosystem functioning and food-web structure analysis.
