Evaluation of tire tread particle toxicity to fish using rainbow trout cell lines

Florian Frédéric Vincent Breider, Kristin Schirmer, Benoît Jean Dominique Ferrari, Gabrielle Léger, Thibault Béranger Masset

Tire and road wear particles (TRWP) resulting from tire abrasion while driving raise concerns due to their potential contribution to aquatic toxicity. Our study aimed to assess cryogenically milled tire tread (CMTT) particle toxicity, used as a proxy for T ...

Bioaccessibility of Organic Compounds Associated with Tire Particles Using a Fish In Vitro Digestive Model: Solubilization Kinetics and Effects of Food Coingestion

Dominique Grandjean, Florian Frédéric Vincent Breider, Kristin Schirmer, Luke Christopher Harris, Benoît Jean Dominique Ferrari, Thibault Béranger Masset

Tire and road wear particles (TRWP) account for an important part of the polymer particles released into the environment. There are scientific knowledge gaps as to the potential bioaccessibility of chemicals associated with TRWP to aquatic organisms. This ...

Interaction of Silver Nanoparticles (AgNP) with Rainbow Trout Gill Cell Lines

Yang Yue

Owing to their unique antimicrobial properties, silver nanoparticles (AgNP) are among the most widely used engineered nanoparticles in a variety of consumer products and medical applications. Their resulting release into the aquatic environment raises conc ...

On the utility of predictive chromatography to complement mass spectrometry based intact protein identification

Hisham Ben Hamidane, Yury Tsybin

The amino acid sequence determines the individual protein three-dimensional structure and its functioning in an organism. Therefore, "reading" a protein sequence and determining its changes due to mutations or post-translational modifications is one of the ...

Phase separation in binary eye lens protein mixtures

Nicolas Dorsaz, Giuseppe Foffi

Liquid–liquid phase separation occurs in young mammalian eye lenses and in concentrated solutions of isolated eye lens proteins, and has been linked to some forms of cataract. Here we study theoretically the protein compositions and cloud temperatures of t ...

Mercury is a direct and potent γ-secretase inhibitor affecting Notch processing and development in Drosophila

Patrick Fraering, Bruno Lemaitre, Mitko Dimitrov, Takayuki Kuraishi, Isabelle Chang

Prenatal exposure to mercury causes neurodevelopmental disorders and neurological pathologies in infants, such as microcephaly and mental retardation. Despite critical importance, the molecular interactions leading to mercury toxicity are yet to be elucida ...

Characterization of the colloidal organic matter from the Amazonian basin by asymmetrical flow field-flow fractionation and size exclusion chromatography

Enrica Alasonati

Colloidal organic matter (COM) collected in small and large watercourse tributaries of the Negro River (Brazil) were fractionated and characterized by an asymmetrical flow field-flow fractionation (AFIFFF) coupled to UV and seven angle laser light scatteri ...

Development of a hyphenated analytical methodology for the fractionation and characterization of environmental colloids

Enrica Alasonati

Natural colloids are defined as macromolecules and nanoparticles with sizes ranging between 1 nm and 1 µm. Colloidal pool is complex "ill-defined" mixture of humic substances, exopolymeric substances (EPS), inorganic oxides, clays, etc. Aquatic colloids ha ...

The affinity precipitation for the isolation of biomolecules

Gisela Stocker Majd

Product isolation increasingly becomes a major bottleneck in molecular biotechnology. This is especially the case for the sensitive proteineous substances (recombinant proteins, antibodies) and lately also DNA, usually produced in low concentration. The cu ...

Micro ion analysis

Xiaoxia Bai

Due to the growing interest on micro total analytical system (μTAS), fast analysis of small amount samples with high throughout is highly desired. Conventional separation techniques, such as Liquid Chromatography, show a great potential for miniaturisation ...
