Article Abstract
Spirolides are cyclic imines whose risks to human health have not been sufficiently evaluated. To determine the possible impact of these compounds in Galicia (NW Spain), their presence and concentration in bivalve mollusk were studied from 2014 to 2021. Only 13-desmethyl spirolide C (13desmSPXC) and an isomer have been detected, and always at low concentrations. Mussel, was the species which accumulated more spirolides, but the presence of its isomer was nearly restricted to cockle, , and two clam species, and . On average, the highest 13desmSPXC levels were found in autumn-winter, while those of its isomer were recorded in spring-summer. Both compounds showed decreasing trends during the study period. Geographically, the concentration tends to decrease from the southern to the north-eastern locations, but temporal variability predominates over spatial variability.

Tralopyril (TP), a representative bromopyrrolonitrile, functions as a broad-spectrum insecticide, raising growing concerns about its potential impact on aquatic organisms and human intestinal health. However, the key targets and toxicity mechanisms underlying TP-induced enteritis remain unclear. In this study, we utilized network toxicology combined with molecular docking to comprehensively explore the potential molecular mechanisms underlying TP-induced enteritis.

Tissue adhesives have emerged as a promising alternative to conventional sutures and staplers in the management of hemostasis, tissue defect sealing, and wound repair. However, the efficacy of current bio-adhesives in clinical practice is compromised by the limitations, including poor wet adhesion, inadequate mechanical strength, vulnerability to gastrointestinal fluids, and insufficient hemostatic performance. Herein, a marine organism-inspired tough and adhesive patch (MOTAP) was developed to address these challenges.

Central Asia, including its freshwater basins, belongs to the Palearctic realm but exhibits significant faunal heterogeneity with localised hotspots of endemism. While several Central Asian countries have been the subject of malacological reviews, Kazakhstan, the largest country of the region, lacks a comprehensive and taxonomically updated species list. The aim of this study is to consolidate all available data on Kazakhstan's freshwater molluscs, critically analyse their species composition, and assess the level of endemism in this group across the country.

Mollusks are among the most ecologically and economically significant invertebrates; yet, their associated microbiomes remain understudied relative to those of other metazoans. This scoping review synthesizes the current literature on the diversity, composition, functional roles, and ecological implications of molluscan microbiomes, with an emphasis on three major groups: gastropods, bivalves, and cephalopods. Drawing on studies from terrestrial, freshwater, and marine systems, we identified the dominant bacterial phyla, including Proteobacteria, Bacteroidetes, and Firmicutes, and explored how microbiota vary across different habitats, diets, tissue types, and host taxonomies.

Dense aggregations of species in the family Pinnidae give soft substrata a specific characterization. They may influence the biological and physical properties of the surrounding sediments. Bottom-trawl samplings performed in the Sea of Marmara revealed populations of a large pinnid species, particularly at depths of 40-45 m in soft substrata.
