.... This is of particular concern given that zebrafish ( Danio rerio ) are an extensively used model organism subject to a wide array of invasive procedures where the level of stress prior to experimentation could pose a major confounding factor. This study, therefore, investigated the impact of both acute and chronic...

... in the heart of zebrafish ( Danio rerio ), a popular model species. Altogether, 18 Ca 2+ channel α-subunit genes were expressed in both atrium and ventricle. Transcripts for 7 L-type (Ca v 1.1a, Ca v 1.1b, Ca v 1.2, Ca v 1.3a, Ca v 1.3b, Ca v 1.4a, Ca v 1.4b), 5 T-type (Ca v 3.1, Ca v 3.2a, Ca v 3.2b, Ca v...

... fail to complete courtship. Because the AR is critical for male-typical behavior, genetic changes in the androgen system could have similar negative effects. The zebrafish ( Danio rerio ) exhibits a complex social repertoire, and is increasingly recognized as an important model in behavioral...

...Laia Ribas; Alejandro Valdivieso; Noelia Díaz; Francesc Piferrer ABSTRACT The zebrafish ( Danio rerio ) has become a well-established experimental model in many research fields but the loss of the primary sex-determining region during the process of domestication renders laboratory strains...

... measured prolonged swimming performance, U crit , and morphology in a large cohort ( n= 461) of wild-type zebrafish ( Danio rerio ) at ∼6 months and again at ∼9 months. Using mixed-model analyses to estimate repeatability as the intraclass correlation coefficient, we determined that U crit...

Ebbesson; Hans van de Vis; Gert Flik; Ruud van den Bos Zebrafish ( Danio rerio Hamilton) are increasingly used as a model to study the effects of chronic stress on brain and behaviour. In rodents, unpredictable chronic stress (UCS) has a stronger...

... in a highly accessible vertebrate model organism, the transparent larval zebrafish ( Danio rerio ), to assess whether they use visual cues to systematically adjust their movements. We found that zebrafish larvae scale the speed and magnitude of turning movements according to the azimuth of one...

... during early development in zebrafish ( Danio rerio ), CA would become necessary for effective CO 2 excretion, and that the pattern of CA expression during early development would reflect this transition. Real-time RT-PCR was used to examine the mRNA expression of the two main intracellular CA isoforms...

... in zebrafish Danio rerio L. reared at 26/27°C from hatching. Fast muscle fibres were produced until 25 mm total length (TL) at 22°C ET, 28 mm TL at 26°C ET and 23 mm TL at 31°C ET. The final fibre number (FFN)showed an optimum at 26°C ET (3600) and was 19% and 14% higher than for the 22°C ET (3000) and 31°C ET...

... in the interaction between fish and water. To study the influence of the relatively high viscous forces compared with adult fish, we mapped the flow around swimming zebrafish ( Danio rerio ) larvae using two-dimensional digital particle image velocimetry (2D-DPIV) in the horizontal and transverse plane of the fish...

..., with the highest rates of excretion occurring during midday of the new photoperiod. In contrast to R. marmoratus , nitrogen excretion rates in the zebrafish Danio rerio remained constant over time. The results of this study show that J urea in R. marmoratus demonstrates the characteristics of a circadian rhythm...

... in the mitochondria. Here we investigate by means of quantitative real-time PCR the changes of hemoglobin, myoglobin, neuroglobin,cytoglobin and globin X mRNA in zebrafish ( Danio rerio ) exposed to mild ( P O 2=∼8.6 kPa) or severe( P O 2=∼4.1 kPa) hypoxia. Neuroglobin and myoglobin protein levels were investigated...

...B. Vulesevic; B. McNeill; S. F. Perry SUMMARY The goals of this study were to assess the respiratory consequences of exposing adult zebrafish Danio rerio to chronic changes in water gas composition (hypoxia, hyperoxia or hypercapnia) and to determine if any ensuing effects could be related...
