A novel form of human disease with a protease-sensitive prion protein and heterozygosity methionine/valine at codon 129: Case report
(BioMed Central, 2010-10)Background: Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare neurodegenerative disorder in humans included in the group of Transmissible Spongiform Encephalopathies or prion diseases. The vast majority of sCJD cases are ... -
Accounting for food availability reveals contaminant-induced breeding impairment, food-modulated contaminant effects, and endpoint-specificity of exposure indicators in free ranging avian populations
(Elsevier, 2021-10-15)It remains unclear how sub-lethal effects of contaminants play out in relation to other stressors encountered by free-ranging populations. Effects may be masked or influenced by interactions with field stressors such as ... -
Accumulation, Depuration, and Biological Effects of Polystyrene Microplastic Spheres and Adsorbed Cadmium and Benzo(a)pyrene on the Mussel Mytilus galloprovincialis
(MDPI, 2022-01-05)Filter feeders are target species for microplastic (MP) pollution, as particles can accumulate in the digestive system, disturbing feeding processes and becoming internalized in tissues. MPs may also carry pathogens or ... -
Advances in Microtechnology for Improved Cytotoxicity Assessment
(Frontiers Media, 2020-11-20)In vitro cytotoxicity testing is essential in the pharmaceutical and environmental industry to study the effects of potential harmful compounds for human health. Classical assays present several disadvantages: they are ... -
An electroactive and thermo-responsive material for the capture and release of cells
(Elsevier, 2021-06-05)Non-invasive collection of target cells is crucial for research in biology and medicine. In this work, we combine a thermo-responsive material, poly(N-isopropylacrylamide), with an electroactive material, poly(3,4-ethyle ... -
Ancient DNA and deep population structure in sub-Saharan African foragers
(Nature, 2022)[EN] Multiple lines of genetic and archaeological evidence suggest that there were major demographic changes in the terminal Late Pleistocene epoch and early Holocene epoch of sub-Saharan Africa(1-4). Inferences about this ... -
Antioxidant activities and selenogene transcription in the european sea bass (Dicentrarchus labrax) liver depend, in a non-linear manner, on the Se/Hg molar tatio of the feeds
(Springer Nature ; Humana Press, 2021-07-01)[EN] Feeding 3.9 and 6.7 mg Hg/kg (Se/Hg molar ratios of 0.8 and 0.4, respectively) for 14 days negatively affected Dicentrarchus labrax growth and total DNTB- and thioredoxin-reductase (TrxR) activities and the transcription ... -
Application of a Biological Multilevel Response Approach in the Copepod Acartia Tonsa for Toxicity Testing of Three Oil Water Accommodated Fractions
(Elsevier, 2021-06-01)Abstract Copepods play a critical role in the marine food webs, being a food source for marine organisms. In this study, we investigated the toxic effects of Water Accommodated Fractions (WAFs) from three types of oil: ... -
Assembly of viral genomes from metagenomes
(Frontiers Research Foundation, 2014-12-18)Viral infections remain a serious global health issue. Metagenomic approaches are increasingly used in the detection of novel viral pathogens but also to generate complete genomes of uncultivated viruses. In silico ... -
Assessment of iron oxide nanoparticle ecotoxicity on regeneration and homeostasis in the replacement model system Schmidtea mediterranea
(Altex, 2019-04-26)Iron oxide nanoparticles (IONs) are used in a number of applications, from food to cosmetics, from medical applications to magnetic storage. In spite of the 550 tons produced each year in Europe alone, no effective dose ... -
Bats Actively Track and Prey on Grape Pest Populations
(Elsevier, 2021-07)There is growing evidence about the role of insectivorous bats against agricultural pests in various crops. Nevertheless, little research addressed the aggregational and functional responses of bat assemblages to changes ... -
Bats from different foraging guilds prey upon the pine processionary moth
(PeerJ, 2019-03-08)Outbreaks of the processionary moth Thaumetopoea pityocampa (Denis & Schiffer-mailer, 1775), a forest pest from the Palearctic, are thought to induce a behavioral response of bats, but up to now the moth has been seldom ... -
Biological Responses and Toxicopathic Effects Elicited in Solea Senegalensis Juveniles by Waterborne Exposure to Benzo[a]pyrene
(Elsevier, 2021-05-11)Polycyclic aromatic hydrocarbons (PAHs) are priority contaminants in coastal and estuarine ecosystems under anthropogenic pressure. Although PAHs tend to accumulate in the sediment, toxicity for benthic flat fish such ... -
BRAF V600E mutational load as a prognosis biomarker in malignant melanoma
(Public Library Science, 2020-03-13)Analyzing the mutational load of driver mutations in melanoma could provide valuable information regarding its progression. We aimed at analyzing the heterogeneity of mutational load of BRAF V600E in biopsies of melanoma ... -
Cell and tissue level responses in mussels Mytilus galloprovincialis dietarily exposed to PVP/PEI coated Ag nanoparticles at two seasons
(Elsevier, 2021-01-01)Silver nanoparticles (Ag NPs) are present in numerous consumer products due to their antimicrobial and other unique properties, thus concerns about their potential input into aquatic ecosystems are increasing. Toxicity of ... -
Coastal gradients of small microplastics and associated pollutants influenced by estuarine sources
(Elsevier, 2022)Small microplastics (SMPs) in the gulf of Cadiz was sampled at 5 m depth by pumping it through the ship's pipe system and filtered through a 45 mu m mesh size net. Our study reveals that higher densities have been found ... -
