Presence of an isoform of H+-pyrophosphatase located in the alveolar sacs of a scuticociliate parasite of turbot: physiological consequences
(Cambridge University Press, 2016-04)H+-pyrophosphatases (H+-PPases) are integral membrane proteins that couple pyrophosphate energy to an electrochemical gradient across biological membranes and promote the acidification of cellular compartments. Eukaryotic ... -
Enzymes involved in pyrophosphate and calcium metabolism as targets for anti-scuticociliate chemotherapy
(Wiley, 2016-07-05)Inorganic pyrophosphate (PPi) is a key metabolite in cellular bioenergetics under chronic stress conditions in prokaryotes, protists and plants. Inorganic pyrophosphatases (PPases) are essential enzymes controlling the ... -

Role of H(+)-pyrophosphatase activity in the regulation of intracellular pH in a scuticociliate parasite of turbot: Physiological effects
(Elsevier, 2016-10)The scuticociliatosis is a very serious disease that affects the cultured turbot, and whose causal agent is the anphizoic and marine euryhaline ciliate Philasterides dicentrarchi. Several protozoans possess acidic organelles ... -
Detection of zoonotic and livestock-specific assemblages of Giardia duodenalis in free-living wild lizards
(Colegio Brasileiro de Parasitología Veterinaria, 2017)Giardia duodenalis is a zoonotic parasite that infects the gut of a wide range of vertebrates, including numerous wildlife species. However, little is known about this protozoan parasite in reptiles. Fecal samples from ... -
Combined antiparasitic and anti‐inflammatory effects of the natural polyphenol curcumin on turbot scuticociliatosis
(Wiley, 2017-01-04)The histiophagous scuticociliate Philasterides dicentrarchi is the aetiological agent of scuticociliatosis, a parasitic disease of farmed turbot. Curcumin, a polyphenol from Curcuma longa (turmeric), is known to have ... -
Wastewater-Based Epidemiology as a New Tool for Estimating Population Exposure to Phthalate Plasticizers
(American Chemical Society, 2017-02-27)This study proposes the monitoring of phthalate metabolites in wastewater as a nonintrusive and economic alternative to urine analysis for estimating human exposure to phthalates. To this end, a solid-phase extraction–liquid ... -
Reaction of diazepam and related benzodiazepines with chlorine. Kinetics, transformation products and in-silico toxicological assessment
(Elsevier, 2017-05-03)In this work, the reaction of four benzodiazepines (diazepam, oxazepam, nordazepam and temazepam) during water chlorination was studied by means of liquid chromatography-quadrupole-time of flight-mass spectrometry (LC-QTOF-MS). ... -
New data on flatfish scuticociliatosis reveal that Miamiensis avidus and Philasterides dicentrarchi are different species
(Cambridge University Press, 2017-09)Scuticociliatosis is a severe disease in farmed flatfish. However, the causative agent is not always accurately identified. In this study, we identified two isolates of scuticociliates from an outbreak in cultured fine ... -
Bioaccumulation of UV filters in Mytilus galloprovincialis mussel
(Elsevier, 2017-09-29)In this study the bioaccumulation kinetics of organic UV filters, such as 4-MBC, BP-3, BP-4, OC and OD-PABA in wild Mytilus galloprovincialis mussels was investigated. The uptake and accumulation of waterborne 4-MBC, BP-4 ... -
Free chlorine reactions of angiotensin II receptor antagonists: Kinetics study, transformation products elucidation and in-silico ecotoxicity assessment
(Elsevier, 2018)Angiotensin II receptor antagonists (ARA II) are widely employed in the treatment of hypertension-related diseases. Because of their partial metabolization and limited biodegradability, these drugs have become ubiquitous ... -
Protocol for cryopreservation of the turbot parasite Philasterides dicentrarchi (Ciliophora, Scuticociliatia)
(Elsevier, 2018-02)Philasterides dicentrarchi is a free-living marine ciliate that can become an endoparasite that causes a severe disease called scuticociliatosis in cultured fish. Long-term maintenance of this scuticociliate in the laboratory ... -
Multi-year inter-laboratory exercises for the analysis of illicit drugs and metabolites in wastewater: Development of a quality control system
(Elsevier, 2018-03-22)Thirty-seven laboratories from 25 countries present the development of an inter-laboratory testing scheme for the analysis of seven illicit drug residues in standard solutions, tap- and wastewater. Almost 10 000 concentration ... -
