Basal forebrain cholinergic neurons are severely depleted early in Alzheimer's disease and appear particularly susceptible to amyloid beta-peptide (A beta) toxicity in vivo. To model this effect in vitro, a cholinergic septal cell line (SN56) was exposed to A beta. SN56 cells exhibited a tetraethylammonium (TEA)-sensitive outward K+ current with delayed(More)
Zinc released from axon terminals in the brain can interact with multiple membrane channels and receptors. However, the specific effects of these Zn(2+)-dependent interactions on physiological processes remains unclear. Because Zn(2+)-containing axon terminals are abundant in the septal region, we selected a septal cell line (SN56) to study the effects of(More)
Turbinella angulata and Busycon perversum are two marine gastropods that support the 90% of conch fisheries in the Gulf of Mexico, nevertheless there is no information available to support a management strategy for both species. The aim of this work was to obtain preliminary fishery information to promote management actions for both species in the Campeche(More)
Proliferation of saccular hair cells of the amphibian, Xenopus laevis, was examined at various stages of development. Numbers of total hair cells and of hair cell bundle types were determined in larval (stages 47, 52 and 56), recently metamorphosed juvenile (1 g), and adult (60 g) animals with scanning electron microscopy (SEM). Hair cells were identified(More)
