The loss and recovery of vertebrate vision examined in microplates.

Regenerative medicine offers potentially ground-breaking treatments of blindness and low vision. However, as new methodologies are developed, a critical question will need to be addressed: how do we monitor in vivo for functional success? In the present study, we developed novel behavioral assays to examine vision in a vertebrate model system. In the assays, zebrafish larvae are imaged in multiwell or multilane plates while various red, green, blue, yellow or cyan objects are presented to the larvae on a computer screen.

Cannabinoid Hyper-emesis Syndrome: An Enigma.

Marijuana is one of the most frequently abused illicit substances in the world especially Australia. Cannabinoid Hyperemesis Syndrome (CHS) is characterized by a triad of symptoms: Cyclic vomiting, chronic marijuana use, and compulsive bathing.
