Neurolin is a member of the superfamily of immunoglobulin-like cell surface receptors. It is essential during neuronal development in the model organism Carassius auratus (goldfish) and involved in the guidance of the growing axon. Among the five extracellular immunoglobulin (Ig) domains, the second Ig domain is crucial for axon pathfinding. In the present study, we report the NMR assignment an...

Goldfish (Carassius auratus, var. japonicus, subvar. bicaudatus) respond to the administration of thyrotrophic hormone with exophthalmos. Eye protrusion increases with simultaneous injections of corticotrophin. Retrobulbar injections of normal saline, human serum or pituitary hormones produce a transient exophthalmos, which is much more persistent when thyrotrophin is injected. Previous treatme...

OBJECTIVE To study the biological effects of nanoscale copper oxide (nCuO), zinc oxide (nZnO), cerium dioxide (nCeO2) and their mixtures on Carassius auratus. METHODS Juvenile fish (Carassius auratus) were exposed to aqueous suspensions of nCuO, nZnO, and nCeO2 (alone and in mixtures) at concentrations of 20, 40, 80, 160, and 320 mg/L. The biomarkers-acetylcholinesterase (AChE) in brain, sodi...
