The rhythmic daytime inhibition of phagocytosis of shed photoreceptor outer segments (OS) by the retinal pigment epithelium (RPE) is related to increased cAMP in RPE cells. Dopamine (DA), the light-adaptive signal of the retinal oscillator can activate adenylyl cyclase through its D1-like receptors. It reduces OS phagocytosis by cultured bovine RPE, but a(More)
Cirripedes (barnacles) are crustaceans that are characterized by a very peculiar body plan, in particular by the lack of an abdomen. To study their body plan, we searched for their engrailed gene. We found two engrailed (en.a/en.b) genes in cirripedes. The two engrailed genes of the rhizocephalan barnacle Sacculina carcini are expressed in the posterior(More)
We report the characterization of a caudal gene from the rhizocephalan cirripede Sacculina carcini and its embryonic and larval expression patterns. Cirripedes are maxillopodan crustaceans that are devoid of any complete abdominal segment at the adult stage. We currently explore the genetic basis of this peculiar body plan. In a previous study we have shown(More)
Cirripedia (barnacles) constitute a crustacean monophyletic taxon which is very well defined by several synapomorphies. In particular, all cirripedes are composed of six thoracic segments, but are devoid of any complete abdominal segment. This body plan is preserved in the adult in non-parasitic groups, while the parasitic rhizocephalan cirripedes(More)
Knowledge of the evaporative loss from lakes and reservoirs is critical to water resources managers as well as to the overall understanding of the water balance in a given basin, geographical region, or continent. Existing methods for ascertaining evaporation from lakes and reservoirs include point measurements, water balance and mass transfer calculations,(More)
Foodborne illness presents a public health challenge in USA. There is an urgent need for the federal government and food industries to expand efforts to prevent any food contamination that potentially could be harmful to human health. The Food Safety Laboratory (FSL), ARS, USDA, is one of the leading laboratories for the development of optoelec-tronic(More)
