The production and use of nanoparticles, as titanium dioxide (nanoTiO2) is growing exponentially in the last years and their release into aquatic environment seem be inevitable. Once into environment, this nanomaterial can interact with other contaminant, as arsenic, and to exert toxic effect in living organisms. So, the objective of present study was to evaluate if the co-exposure to nanoTiO2 (1 mg/L) can alter the As effect (nominal concentration of 50 μg/L) in the estuarine polychaeta Laeonereis ...

In recent times, however, due to the emergence of bacterial strains with resistance to conventional antibiotics, silver has again gained attention as an alternative for developing new efficient bactericides, including the use of silver nanoparticles (AgNPs). However, the improper disposal of these items after use may cause toxicological effects on organisms in the environment. To evaluate the potential environmental hazard of nanosilver-coated dressings, the nematode Caenorhabditis elegans was chosen ...

Although some studies have showed the effects of different crystalline structures of nTiO2 (anatase and rutile) and their applicability in several fields, few studies has analyzed the effect of coexposure with other environmental contaminants such as copper. Thus, the objective of this study was to evaluate if the coexposure to nTiO2 (nominal concentration of 1 mg/L; anatase or rutile) can increase the incorporation and toxic effect induced by Cu (nominal concentration of 56 μg/L) in different tissues ...

This study was conducted in two estuarine inlets (Saco da Mangueira and Saco do Arraial) at the Patos Lagoon estuary, southern Brazil. The changes in relative abundance and size of post-larvae and juvenile shrimp Farfantepenaeus paulensis and juvenile blue crab Callinectes sapidus were compared, considering the influence of salinity and the presence of submerged seagrass meadows. The analyses were performed using generalized linear models (GLM) for abundance variations and ANOVA for variations on ...

Aquatic animals are vulnerable to arsenic (As) toxicity. However, rarely does a contaminant occur alone in the aquatic environment. For this reason, this study was conducted to evaluate whether titanium dioxide nanoparticles (nTiO2) can interfere with the effects induced by As in Litopenaeus vannamei. Arsenic accumulation and metabolic capacity; expression and enzymatic activity of GSTΩ (glutathione-S-transferase omega isoform); antioxidant responses such as GSH, GR, and GST (reduced glutathione levels, ...

In the present study, different in vitro and electrochemical protocols were employed to determine the mitoprotective properties of carbon nanotubes family (pristine-CNT, oxidized-CNT) based on free radical scavenging ability against the most aggressive reactive oxygen species (ROS) as hydroxyl radical (·OH) formed by Fenton-Haber-Weiss reaction, which was experimentally induced on isolated rat-liver mitochondria through Fe2+ ions overload. The results suggest that the mitochondrial Fenton-inhibition ...

Bacterial exopolysaccharides (EPSs) are mono- or oligo-saccharide units linked by glycosidic bonds, forming homo- or hetero-polymers. In gut commensals, these macromolecules are claimed to protect bacterial cells against gastrointestinal challenges and to be involved in modulating the cross talk between the producing bacterium and its gut environment. The predicted EPS arsenal of the Bifidobacterium genus, which we designate here as the eps-ome, consists of 9 eps gene clusters conserved among different ...

Abstract Gamma aminobutyric acid (GABA) is the principal inhibitory neurotransmitter playing a key role in anxiety and depression disorders in mammals. Recent studies revealed that members of the gut microbiota are able to produce GABA modulating the gut–brain axis response. Among members of the human gut microbiota, bifidobacteria are well known to establish many metabolic and physiologic interactions with the host. In this study, we performed genome analyses of more than 1,000 bifidobacterial strains ...

ABSTRACT The ability of bifidobacteria to establish in the intestine of mammals is among the main factors considered to be important for achieving probiotic effects. The role of surface molecules from Bifidobacterium bifidum taxon in mucin adhesion capability and the aggregation phenotype of this bacterial species was analyzed. Adhesion to the human intestinal cell line HT29 was determined for a collection of 12 B. bifidum strains. In four of them— B. bifidum LMG13195, DSM20456, DSM20239, and A8— ...
