5S rRNA and Accompanying Proteins in Gonads: Powerful Markers to Identify Sex and Reproductive Endocrine Disruption in Fish
(ACS, 2012-06-22)In anuran ovaries, 5S rDNA is regulated transcriptionally by transcription factor IIIA (TFIIIA), which upon transcription, binds 5S rRNA, forming 7S RNP. 5S rRNA can be stockpiled also in the form of 42S RNP bound to 42sp43. ... -
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 ... -
Acute toxicity of zinc and arsenic to the warmwater aquatic oligochaete Branchiura sowerbyi as compared to its coldwater counterpart Tubifex tubifex (Annelida, Clitellata)
(Springer, 2016-07-12)Purpose This study aimed at evaluating the acute effects of arsenic and zinc to the warmwater aquatic oligochaete Branchiura sowerbyi. Relative sensitivity with the coldwater species Tubifex tubifex was compared. Implications ... -
Addressing the Joint Impact of Temperature and pH on Vibrio harveyi Adaptation in the Time of Climate Change
(MDPI, 2023-04-20)Global warming and acidification of the global ocean are two important manifestations of the ongoing climate change. To characterize their joint impact on Vibrio adaptation and fitness, we analyzed the temperature-dependent ... -
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 ... -
Alteration in molecular markers of oocyte development and intersex condition in mullets impacted by wastewater treatment plant effluents
(Elsevier, 2016-06-11)Wastewater Treatment Plant (WWTP) discharges are an important source of endocrine disrupting chemicals (EDCs) into the aquatic environment. Fish populations inhabiting downstream of WWTP effluents show alterations in gonad ... -
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 ... -
Apoptosis and autophagy-related gene transcription during ovarian follicular atresia in European hake (Merluccius merluccius).
(Elsevier, 2023-01)Follicular atresia is an energy-saving oocyte resorption process that can allow the survival of female fish when environmental conditions are unfavourable and at the expense of fecundity. This study investigated the ... -
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 ... -
Assessment of the effectiveness of antifouling solutions for recreational boats in the context of marine bioinvasions
(Elsevier, 2024-03)The recreational boating sector is a major vector for the introduction of non-indigenous species (NIS) via biofouling. Despite applying control measures to prevent the growth of fouling communities, most vessels are NIS ... -
