Spectral distribution of the negative potential in the cichlid electroretinogram


, : Spectral distribution of the negative potential in the cichlid electroretinogram. Experientia 37(12): 1299-1300

A negative potential occurring in the ERG of certain cichlid fishes shows a unique set of properties when evoked by monochromatic light. Spectral distributions determined for Cichlasoma octofasciatum and Hemichromis bimaculatus show a blue (460-478 nm) maximum. no Purkinje shift upon light adaptation, and secondary peaks correlated with the species' behavioral preferences in reproduction and parental care.

Chitin was found to induce matrix metalloproteinases (MMPs) activity in rat skin and subcutaneous tissue. Sponge type chitin (22.5 mg) was implanted in subcutaneous tissue of 8-week-old rats (n = 21) by skin incision. MMPs activity was more pronou...

Background: Erythropoietin alfa (Epoietin) has been FDA-approved for the treatment of anemia associated with renal failure, chemotherapy and HIV disease. Anemia is often observed in liver disease but the post-liver transplantation (OLT) setting ha...

Whereas no progress has been made in the diagnosis of early tumors, the staging of pancreatic cancer has improved, mainly through the introduction of ultrafast MRI, resulting in a higher resection rate. The early results of standard pancreatectomy...

The factors affecting the variation of shell color morph frequencies of the interidal snail L. rudis Maton were examined using ordination and correlation techniques. The major gradient underlying variation in shell color is related to habitat type...
