Dependence of pH values in the digestive tract of freshwater fishes on some abiotic and biotic factors
(Springer, 2017-10-09)
The values of pH in the digestive tracts of 20 freshwater fish species inhabiting various Russian Federation waterbodies were studied. Only in six species (Coregonus lavaretus, Coregonus migratorius, ...
Occurrence of cyclic imines in European commercial seafood and consumers risk assessment
(Elsevier, 2017-12-01)
Cyclic imines constitute a quite recently discovered group of marine biotoxins that act on neural receptors and that bioaccumulate in seafood. They are grouped together due to the imino group functioning ...
Herbivore control in connected seascapes: habitat determines when population regulation occurs in the life history of a key herbivore
(Wiley, 2018-02-08)
Herbivore outbreaks often trigger catastrophic overgrazing events in marine macrophyte ecosystems. The sea urchin Paracentrotus lividus, the dominant herbivore of shallow Mediterranean seascapes, is ...
Chimeric camel/human heavy-chain antibodies protect against MERS-CoV infection
(American Association for the Advancement of Science, 2018-08-08)
Middle East respiratory syndrome coronavirus (MERS-CoV) continues to cause outbreaks in humans as a result of spillover events from dromedaries. In contrast to humans, MERS-CoV–exposed dromedaries develop ...
Temperature responsiveness of gilthead sea bream bone; an in vitro and in vivo approach
(Springer Nature, 2018-07-25)
This study aimed to characterize the molecules involved in osteogenesis in seabream and establish using in vitro/in vivo approaches the responsiveness of selected key genes to temperature. The impact ...
The cellular localization and redistribution of multiple aquaporin paralogs in the spermatic duct epithelium of a maturing marine teleost
(Wiley, 2018-05-27)
Aquaporin‐mediated fluid transport in the mammalian efferent duct and epididymis is believed to play a role in sperm maturation and concentration. In fish, such as the marine teleost gilthead seabream ...
Do the Escherichia coli European Union shellfish safety standards predict the presence of Arcobacter spp., a potential zoonotic pathogen?
(Elsevier, 2017-12-27)
The genus Arcobacter comprises Campylobacter-related species, considered zoonotic emergent pathogens, the presence of which in water has been associated with fecal pollution. Discharges of fecal polluted ...
Skeletogenesis in the Persian sturgeon Acipenser persicus and its correlation with gene expression of vitamin K‐dependent proteins during larval development
(Wiley, 2018-01-18)
The present study describes morphological development of the skeleton in the Persian sturgeon Acipenser persicus and discusses the hypothesis that expression of genes encoding vitamin K‐dependent proteins ...
The future of biotic indices in the ecogenomic era: Integrating (e)DNA metabarcoding in biological assessment of aquatic ecosystems
(Elsevier, 2018-05-22)
The bioassessment of aquatic ecosystems is currently based on various biotic indices that use the occurrence and/or abundance of selected taxonomic groups to define ecological status. These conventional ...
Multi-Target Strategy for Pan/Foot-and-Mouth Disease Virus (FMDV) Detection: A Combination of Sequences Analysis, in Silico Predictions and Laboratory Diagnostic Evaluation
(Frontiers Media, 2018-07-12)
Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting cloven-hoofed animals that causes severe economic losses. The disease is characterized by a vesicular condition and it cannot ...
