Zebrafish

Abstract The analysis of behavior in animal models is an important objective in many research fields, including neuroscience, psychology, toxicology, and neuropsychopharmacology. Animal models have been used for many years, and several behavioral ...

Abstract Zebrafish embryos and larvae have become popular vertebrate models because their body walls are transparent, which enables live imaging of target organs using fluorescent protein transgenes or dye staining. Software packages for the ...

Abstract Peptides represent a large class of cell signaling molecules, and they are mainly produced by the classical secretory pathway or during protein degradation. The peptide profile of Danio rerio (zebrafish) shows a lack of information when compared ...

Abstract Vitrification is a method of cryopreservation that freezes samples rapidly, while forming an amorphous solid (“glass”), typically in small (μL) volumes. The goal of this project was to create, by three-dimensional (3D) printing, open ...

Abstract The zebrafish has become an appropriate animal model in the analysis of numerous human brain disorders. A variety of neuropsychiatric conditions and neurodevelopmental disorders are comorbid with abnormal social behavior. Given the translational ...

Abstract Diet modulates the gut microbiota and is one of the main factors promoting obesity and overweight. In the present study, we investigated the effect of a high-fat diet (HFD) on the gut microbiota of the zebrafish (Danio rerio). Fish were separated ...

Abstract Fixation and decalcification can alter protein structure in tissues, influencing the efficacy of primary antibodies routinely used in immunohistochemical (IHC) staining. Histologic examination of zebrafish requires both processes, making staining ...

Abstract Zebrafish have been extensively used as a model system for research in vertebrate development and pathogen–host interactions. We describe the complete genome of a novel picornavirus identified during a viral metagenomics analysis of zebrafish gut ...

Abstract Zebrafish is a model species with a high variability of feeding regimes among fish facilities. The use of live feeds for early life stages is a common practice, and few studies have focused early weaning into microdiets. The lack of standardized ...

Abstract Electric fish of the order Gymnotiformes are endemic to the Neotropical region, and their highest diversity is observed in the Amazon region. The family Gymnotidae, which consists of the genera Electrophorus and Gymnotus, is a natural group and ...

Abstract We developed an easy, efficient, and cheap protocol for zebrafish sperm cryopreservation carried out on dry ice (20 min) using simple composition solution (200 mM glucose, 40 mM KCl, 30 mM Tris, pH = 8.0). The average efficiency of the present ...

Abstract The Nordic zebrafish and husbandry meeting took place at Karolinska Institutet in Stockholm, November 7–9, 2018. More than 120 scientists from Europe joined this meeting, which also attracted world-leading keynote speakers such as Zoltan Varga, ...
