PARASITE FAUNA OF TAMBAQUI REARED IN NET-CAGES AT TWO STOCKING DENSITIES
Boletim do Instituto de Pesca, 2019 This study investigated the parasite fauna in Colossoma macropomum reared at two stocking densities in net-cages of a fish farm in the Matapi River, State of Amapá. Before stocking fish in the net-cages for fattening, fish were examined for parasites and

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Simulated Fishing to Untangle Catchability and Availability in Fish Abundance Monitoring [PDF]
San Francisco Estuary and Watershed Science, 2020 In fisheries monitoring, catch is assumed to be a product of fishing intensity, catchability, and availability, where availability is defined as the number or biomass of fish present and catchability refers to the relationship between catch rate and the true population.

Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Spatial and temporal variation of fish assemblage structure in a neotropical Mexican river
Revista Mexicana de Biodiversidad, 2021 The introduction of non-native fish into the Teuchitlán River, in west-central Mexico, was suggested as a key factor behind the change in the fish assemblage, and even in the extinction of endemic species. The characterization of the fish assemblage and
