Despite the large number of animal complete mitochondrial genomes currently available in public databases, knowledge about mitochondrial genomics in invertebrates is uneven. This paper reports, for the first time, the complete mitochondrial genome of the grooved carpet shell, Ruditapes decussatus, also known as the European clam. Ruditapes decussatus is morphologically and ecologically similar ...

This work presents the results of a short-term natural detoxification experiment carried out with the contaminated Manila clam (Tapes philippinarum), an edible bivalve species subjected to intense exploitation in the Venice Lagoon. The concentrations of seventeen PCDD/F congeners and twelve dioxin-like PCBs were determined in sediments as well as T. philippinarum specimen sampled in a lagoon ar...

Cyclophilin A (CypA) is a ubiquitously distributed intracellular protein belonging to the immunophilin family, which is recognized as the cell receptor for the potent immunosuppressive drug cyclosporine A. In the present study, two isoforms of cyclophilin A gene (named as VpCypA1 and VpCypA2) were isolated and characterized from Venerupis philippinarum by RACE approaches. Both VpCypA1 and VpCyp...

Dipeptidyl peptidase-IV (DPP-IV) inhibitory peptides were rapidly identified from Ruditapes philippinarum hydrolysate. The hydrolysate was fractionated by ethanol precipitation and preparative reverse phase high-performance liquid chromatography (RP-HPLC). The fraction which showed the highest DPP-IV inhibitory activity was then analyzed by a high-throughput nano-liquid chromatography electrosp...

A monthly survey of the feeding selectivity Ruditapes philippinarum in Yalu River Estuary 2020–2021 was conducted using high-throughput sequencing identification and visual grading technology. The results showed that most-dominant species water shellfish culture area stomachs R. Karlodinium veneficum those years. index (E) indicated avoided consuming Bacillariophyta, Chrysophyta Cryptophyta thr...

Brown Ring Disease (BRD) in the Manila clam, Ruditapes philippinarum, is a disease caused by the bacterium Vibrio tapetis. This pathology was first observed in Northern Brittany (France) in 1987. The pathogenic agent enters in the extrapallial cavity (i.e. the space between mantle and shell), disrupts the normal production of periostracal lamina and causes an anomalous deposition of periostracu...

The mineral phase of shell repair in the Manila clam Venerupis philippinarum affected by brown ring disease (BRD) was characterised at various scales and at various stages of shell repair by confocal Raman microspectrometry and scanning electron microscopy. Spherulitic and quadrangular aragonite microstructures associated with polyene pigments were clearly observed. Von Kossa staining showed th...

The burrowing responses of a common tropical bivalve, the short-neck clam Ruditapes philippinarum, to cadmium (Cd)-spiked sediment, variations of sediment grain size and natural sediments collected from 15 locations in Hong Kong's inshore waters were investigated through a series of laboratory tests. Results showed that the burrowing response exhibited a negative relationship with an increase i...
