Article Abstract
Oysters are recognized for flavor and health benefits, but their shells are regarded as waste, contributing to resource inefficiency. This study investigates the chemical composition and pharmacological activity of oyster shells, using a fraction partitioning approach to separate the oyster shells water extract (WE) into two fractions: WE of extra-membranous (WEE, <1000 kDa) and intra-membranous (WEI, >1000 kDa). Using UPLC-Q-Exactive MS, 231 components were identified such as organic acids, amino acids. ELISA analysis revealed that high-dose WEE significantly increased serum T3, T4, FT3, and FT4 levels while reducing TSH, and improved thyroid tissue lesions. Network pharmacology identified 291 drug-disease intersection targets enriched in the PI3K/AKT pathway. Furthermore, the RT-qPCR and WB results showed that high-dose WEE protected against propylthiouracil-induced goitre by inhibiting the PI3K/AKT/Bcl-2 pathway. This study evaluated the anti-goitre potential properties of WE and provided a theoretical basis for further development of oyster shells as a functional food source.

Application of oyster shells for environmental remediation of sewage-affected coastal sediments in Masan Bay, Korea.

Coastal sediments in semi-enclosed bays are particularly susceptible to contamination due to limited water circulation and ongoing contaminant input. In Masan Bay, a heavily impacted coastal area in Korea, sediment remediation is essential to alleviate the effects of organic enrichment and hypoxia. This study investigated the effectiveness of oyster shell capping as an in-situ remediation technique by assessing its impact on sediment environment, microbial communities, and macrobenthic fauna.

Background: The phenomenon of increased toughness of adductor muscle of Pacific oysters (Crassostrea gigas) during heat treatment considerably impacts their palatability. Thus, the present study was conducted aiming to investigate the relationship between the adductor muscle proteins and observed toughness.
Results: During heat treatment with boiling, the smooth muscle exhibited greater difficulty in detaching from the shell compared to the striated muscle, indicating more pronounced toughness.
Oyster farming acts as a marine carbon dioxide removal (mCDR) hotspot for climate change mitigation.

Bivalve farming, a vital component of global aquaculture, has been proposed as a potential marine carbon dioxide removal (mCDR) strategy, yet its role remains contentious. Using field mesocosms, we demonstrate that oyster filter-feeding enhances mCDR by accelerating the formation of particulate and dissolved organic carbon in the water column and promoting organic carbon deposition in sediments. This process shifts the water column toward a more autotrophic and alkaline state, effectively sequestering CO from the atmosphere.

The present study quantifies mercury (Hg) concentrations in mangrove oysters () and assesses their potential as biomonitors of Hg contamination in the Parnaíba River Delta (PRD), located on the equatorial coast of Brazil (ECB). The highest Hg concentrations occurred in the smallest individuals' size class (20-40 mm) from the main channel of the Parnaíba River (52.1 to 195.

Although bivalves are widely recognized as indicators of microplastic pollution, evidence of bioaccumulation shows high variability across studies due to exposure duration and depuration rates. This study examined microplastic ingestion in wild oysters of varying sizes (spat to adult) over three months in the Maowei Sea, a mariculture bay in China. Results revealed a positive correlation between oyster size and microplastic ingestion per individual, with larger oysters accumulating more microplastics, primarily in the visceral mass and mantle compared with the gills.
