Due to the potential hazard of diclofenac on aquatic organisms and lack higher-tier ecotoxicological studies, a long-term freshwater mesocosm experiment was set up study effects this substance primary producers consumers at environmentally realistic nominal concentrations 0.1, 1 10 µg/L (average effective 0.041, 0.44 3.82 µg/L). During six-month exposure period, biovolume two macrophyte species (Nasturtium officinale Callitriche platycarpa) significantly decreased highest treatment level....
The objective of this study was to evaluate if freshwater bivalves can be used detect the presence Toxoplasma gondii in water bodies. Zebra mussels (Dreissena polymorpha) were caged for 1 month upstream and downstream discharge points wastewater treatment plants (WWTPs). Physiological status assessed assure good health during transplantation. T. investigated mussel tissues by qPCR. In autumn, detected two WWTPs. spring, it one WWTP. For first time, DNA has been shown a continental mollusc...
Nowadays, biomarkers are recognized as valuable tools to complement chemical and ecological assessments in biomonitoring programs. They provide insights into the effects of contaminant exposures on individuals establish connections between environmental pressure biological response at higher levels. In last decade, strong improvements design experimental protocols result interpretation facilitated use biomarker across wide geographical areas, including aquatic continua. Notably, statistical...
Abstract Biological responses of zebra mussel Dreissena polymorpha are investigated to assess the impact contaminants on aquatic organisms and ecosystems. In addition concentrate chemical in their tissues, mussels accumulate several microorganisms such as viruses, protozoa bacteria. order understand molecular mechanisms involved defence against this study aims at identifying immune proteins from D. hemolymph viruses. For purpose, were exposed ex vivo Cryptosporidium parvum RNA poly I:C....
Abstract Background Several biomarkers developed from freshwater sentinel species are used to complement chemical assessment of ecosystems and improve the evaluation their contamination levels. While active biomonitoring strategies allow compare biological data in field, lack criteria interpret modulations restricts application surveys. For this purpose, determination threshold values emerges as a relevant approach support biomarker-based diagnosis within Based on distribution baselines,...
Massive mortality outbreaks affecting Pacific oysters ( Crassostrea gigas ) spat/juveniles are often associated with the detection of a herpesvirus called ostreid type 1 (OsHV-1). In this work, experimental infection trials C. spat OsHV-1 were conducted using two contrasted oyster families for their susceptibility to viral infection. Live sampled at 12, 26, and 144 h post (hpi) analyze host-pathogen interactions comparative proteomics. Shotgun proteomics allowed seven proteins in infected...
The environmental neurotoxin β-N-Methylamino-l-alanine (BMAA) has been pointed out to be involved in human neurodegenerative diseases. This molecule is known bioaccumulated by bivalves. However, little data about its toxic effects on freshwater mussels available, particularly the hemolymphatic compartment and hemocyte cells various physiological processes such as immune defenses, digestion excretion, tissue repair, shell production. Here we exposed Dreissena polymorpha dissolved BMAA, at...
A new class of betaine-based ionic liquids (ILs) have been synthesized. Betaine is transformed into betaine amides with various anions. These were prepared at first through a classical four-step method; the synthesis was then improved by reducing number steps using one-pot strategy for amidation. The final yields good to high, and structures fully characterized valorize them in many domains such as catalysis, extraction, or dissolution biopolymers. Next, determine their ecotoxicity,...
Proteogenomic methodologies have enabled the identification of protein sequences in wild species without annotated genomes, shedding light on molecular mechanisms affected by pollution. However, proteomic resources for sentinel are limited, and organ-level investigations necessary to expand our understanding their biology. This study presents obtained from proteogenomic analyses key organs (hepatopancreas, gills, hemolymph) three established aquatic invertebrate interest...
