Barium suppresses slow PIII in perfused bullfrog retina
Under the appropriate conditions a large, slow, negative-going potential change can be recorded from the vertebrate retina in response to a light stimulus. This slow PHI, as it has come to be called,Expand

The effect of lead on photoreceptor response amplitude--influence of removing external calcium and bleaching rhodopsin.
The relationship between the effect of lead on the amplitude of the photoreceptor response to light and the ability of the photoreceptor response to be enhanced by a light stimulus was studied in theExpand

Light-induced phosphorylation of proteins from the all-cone retina of the lizard, Anolis carolinensis.
Proteins from the all-cone retina of the lizard Anolis carolinensis were phosphorylated using [gamma 32P] ATP, separated by SDS-PAGE and detected by autoradiography. Several proteins incorporatedExpand

Low molecular weight mRNA encodes a protein that controls serotonin 5- HT1c and acetylcholine M1 receptor sensitivity in Xenopus oocytes
Serotonin 5-HT1c and acetylcholine M1 receptors activate phosphoinositidase, resulting in an increased formation of IP3 and 1,2 diacylglycerol. In Xenopus oocytes injected with mRNA encoding eitherExpand

The effects of lead and of cadmium on the mass photoreceptor potential: the dose-response relationship.
The effects of micromolar (1.0-60.0 microM) amounts of lead and of cadmium on the light response of photoreceptors were studied using the isolated, perfused bullfrog retina. The effect of lead inExpand

The effect of lead on photoreceptor response amplitude--influence of the light stimulus.
The mass receptor potential of the excised, superfused retina of the bullfrog was studied. Photoreceptor responses were isolated by addition of sodium aspartate to the Ringer solutions. Responses ofExpand

Identification of a peanut agglutinin-binding protein from human retina.
With the use of an antiserum raised to peanut agglutinin (PNA)-binding protein(s) from human retinas, we have identified a glycoprotein that has the same subunit molecular weight (135,000) as humanExpand

Genetic studies of H group plasmids by bacteriophage P1 transduction.
Bacteriophage P1 transduction was used to study the incompatibility group H1 plasmid pRG1251, molecular weight 120 x 10(6), and the incompatibility group H2 plasmid pSD114, molecular weight 166 xExpand

Dichotomous effects of cadmium on the cone photoreceptor response to light.
The effects of cadmium (1.0 to 400.0 microM CdCl2) on the cone photoreceptor's response to light were studied in the superfused bullfrog retina. The effects of cadmium were complex, characterized byExpand

The influence of calcium on the aspartate-isolated mass receptor potential of bullfrog cones.
The aspartate-isolated receptor potential was studied in the excised, perfused bullfrog retina. Cones were monitored without interference from rods by employing conditioning and test stimuli in aExpand
