The ubiquitous presence of microplastics (MPs) in the environment is a major concern for conservation biodiversity. Numerous studies show detrimental effects MPs on marine species, especially because their small size and capacity to absorb organic contaminants from surroundings. bivalve mollusk Cerastoderma glaucum (Bruguière, 1789), its wide geographic distribution immobile feeding habits, can be used as sentinel bioindicator species. By examining presence, localization, co-localization Toll-like receptor 2 (TLR2) inducible nitric oxide synthetase (iNOS), this study aims evaluate response internal defense system C. pristine through employment confocal microscopy bioinformatics techniques. results haemocytes immunoreactive antibodies tested; particular, higher number TLR2-positive observed group exposed MPs.

Invertebrates show great diversity in their responses to neural damage. Numerous invertebrate phyla, including gastropods, can replace all or a portion of nervous systems. Aplysia species have been utilized extensively toxicology, ecology, and neuroscience because neurological systems react bodily harm by releasing trophic substances that stimulate non-neural tissue regeneration induce changes the system. This study aims assess putative role hemocytes depilans (Gmelin, 1791) analyzing presence Toll-like receptor 2, inducible nitric oxide synthetase, and, particular, vimentin α-tubulin, molecules potentially implicated process regeneration. The results demonstrate aforementioned proteins are present hemocytes, suggesting defense response possible contribution neuronal this gastropod. These data provide deeper insight into internal system mollusk.

Abstract The skin of snakes acts as the first interface between these reptiles and environment they live in. It plays an important role in ecology organisms, specialised structures, such tactile corpuscles, are crucial sensing a wide variety stimuli. This study, by examining presence, localisation colocalisation serotonin, substance P, PGP 9.5 tubulin, wants to demonstrate sensory that structures play Green whip snake Hierophis viridiflavus (Lacépède, 1789). study presents evaluation nerve immune molecules (TLR2) corpuscles H. viridiflavius ventral skin, indicating potential defence structures. These findings provide valuable information on snakes, their systems, evolutionary morphostructural adaptations. Additionally, identification could support for taxonomic recognition. Furthermore, this expands knowledge about stimuli snakes.

Contaminants of emerging concern (CECs) are compounds found in several environmental compartments whose ubiquitous presence can cause toxicity for the entire ecosystem. Several personal care products, including antibiotics, have entered this group compounds, constituting a major global threat. It is essential to develop simple and reliable methods by which quantify these contaminants matrices. In work, mussels were chosen as sentinel organisms assess pollution safety bivalve mollusk consumption according “One Health perspective”. A liquid chromatographic tandem mass spectrometry method (LC-MS/MS) was developed quantification two macrolides, erythromycin (ERY) azithromycin (AZI), mussels. This new validated international guidelines, showing high selectivity, good recoveries (>60% both them), sensitivity, precision. The successfully applied ERY AZI research farmed along Sardinian coasts (Italy), demonstrating itself be useful routine analysis competent authorities. tested macrolides not determined analyzed sites at concentrations above limits detection (LODs). These results demonstrate food (as concerns studied antibiotics) negligible amount derived from drugs area.
