[EX Q]: Nanoparticles (NPs) in contact with biological fluids become covered by a tightly bound layer of proteins, the "protein corona", and it is largely accepted that this corona gives a new identity to NPs in biological milieu. We here consider the exposing scenario of NPs through an environmental route exemplified by the use of hydrophobins, highly adhesive proteins that are secreted into the environment in large quantities by fungi. HFBII of Trichoderma reesei has been used as a model protein and we have shown strong binding to polystyrene NPs of different sizes and surface groups. Hydrophobin coated NPs are shown to strongly increase the stability and the dispersion when exposed to human plasma compared to pristine ones particles. It is also shown that the presence of hydrophobin on the NPs results in an attenuated protein corona formation, in a different corona composition, and we also show that hydrophobin remained strongly associated to the NPs in competition with plasma proteins. As a conclusion we therefore suggest that the route of exposure of nanoparticles strongly affects their surface properties and their possible physiological behavior.
[EX A]: Does an environmental route of exposure affect the formation of nanoparticle coronas in blood plasma?

[EX Q]: The dietary determinants of adolescent blood pressure (BP) are not well understood. We determined the association between major dietary patterns and BP in a sample of Iranian adolescents.', "This cross-sectional study was conducted among a representative sample (n\xa0=\xa0557) of Shirazi adolescents aged 12-19\xa0years. Participants' systolic and diastolic BP was measured using a validated oscillometric BP monitor. Usual dietary intakes during the past 12\xa0months were assessed using a valid and reproducible 168-item semiquantitative food frequency questionnaire through face-to-face interviews. Principal component factor analysis was used to identify major dietary patterns based on a set of 25 predefined food groups.", 'Overall, three major dietary patterns were identified, among which only the Western pattern (abundant in soft drinks, sweets and desserts, salt, mayonnaise, tea and coffee, salty snacks, high-fat dairy products, French fries, and red or processed meats) had a significant association with BP. After adjusting for potential confounders in the analysis of covariance models, multivariable adjusted means of the systolic and mean BP of subjects in the highest tertile of the Western pattern score were significantly higher than those in the lowest tertile (for systolic BP: mean difference 6.9\xa0mmHg, P\xa0=\xa00.001; and for mean BP: mean difference 4.2\xa0mmHg, P\xa0=\xa00.003). A similar but statistically insignificant difference was observed in terms of diastolic BP.
[EX A]: Is a Western dietary pattern associated with higher blood pressure in Iranian adolescents?

[EX Q]: Populations of Atlantic salmon display highly significant genetic differences with unresolved molecular basis. These differences may result from separate postglacial colonization patterns, diversifying natural selection and adaptation, or a combination. Adaptation could be influenced or even facilitated by the recent whole genome duplication in the salmonid lineage which resulted in a partly tetraploid species with duplicated genes and regions.', 'In order to elucidate the genes and genomic regions underlying the genetic differences, we conducted a genome wide association study using whole genome resequencing data from eight populations from Northern and Southern Norway. From a total of ~4.5 million sequencing-derived SNPs, more than 10\xa0% showed significant differentiation between populations from these two regions and ten selective sweeps on chromosomes 5, 10, 11, 13-15, 21, 24 and 25 were identified. These comprised 59 genes, of which 15 had one or more differentiated missense mutation. Our analysis showed that most sweeps have paralogous regions in the partially tetraploid genome, each lacking the high number of significant SNPs found in the sweeps. The most significant sweep was found on Chr 25 and carried several missense mutations in the antiviral mx genes, suggesting that these populations have experienced differing viral pressures. Interestingly the second most significant sweep, found on Chr 5, contains two genes involved in the NF-KB pathway (nkap and nkrf), which is also a known pathogen target that controls a large number of processes in animals.
