Activation of Protein Kinase C Modulates Light Responses in Horizontal Cells of the Turtle Retina
(Blackwell Publishing Ltd, 1992-08)
The effect of phorbol esters on the light-evoked responses of horizontal cells were studied in the turtle eyecup preparation. Phorbol esters caused a reduction in receptive field size and a significant decrease in the ...
In vitro intracellular recordings from gustatory neurons in the rat solitary nucleus
(Elsevier, 1990-01-29)
The passive membrane properties of neurons in the gustatory zone of the nucleus tractus solitarius (NTS) of rats were studied using an in vitro brain slice preparation. Examination of responses evoked by a 0.5 nA, 100 ms ...
Agonist-Specific Calcium Signaling and Phosphoinositide Hydrolysis in Human SK-N-MCIXC Neuroepithelioma Cells
(Blackwell Science Ltd, 1994-12)
Fura-2 digital imaging microfluorimetry was used to evaluate the Ca 2+ signals generated in single clonal human neuroepithelioma cells (SK-N-MCIXC) in response to agonists that stimulate phosphoinositide hydrolysis. Addition ...
Bombesin-Stimulated Acetylcholine Release from Myenteric Plexus Neurons
(Elsevier, 1993-05)
The ability of bombesin to stimulate acetylcholine release from guinea pig myenteric plexus neurons was studied using a primary neuronal culture system. Bombesin caused dose-dependent increases in [3H]acetylcholine (ACh) ...
Membrane Polarity of the Na+-K+ Pump in Primary Cultures of Xenopus Retinal Pigment Epithelium
(Elsevier, 1994-11)
The retinal pigment epithelium is a transporting epithelium that helps regulate the volume and composition of the subretinal space surrounding photoreceptor outer segments. The capacity of the RPE to actively transport Na+ ...
Cardiac function and microsphere blood flow distribution in the brain-dead dog
(Elsevier, 1992-06)
The mechanisms for the deterioration of the brain-dead organ donor are not clearly defined. We measured myocardial blood flow and function during the 4 hours after the induction of brain death in dogs. Brain death was ...
Inhibition of binding of phospholipase CΓ1 SH2 domains to phosphorylated epidermal growth factor receptor by phosphorylated peptides
(Blackwell Publishing Ltd, 1993-09)
Substance P excites neurons in the gustatory zone of the rat nucleus tractus solitarius
(Elsevier, 1993-08-13)
Whole-cell patch recordings of neurons in the rostal (gustatory) nucleus tractus solitarius (rNTS) were performed in a brain slice preparation from rat medulla. Neural responses to brief applications (10-45 s) of substance ...
Retrotransposons and the evolution of mammalian gene expression
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-01)
Transposable elements, and retroviral-like elements in particular, are a rich potential source of genetic variation within a host's genome. Many mutations of endogenous genes in phylogenetically diverse organisms are due ...
Spinal antinociception mediated by a cocaine-sensitive dopaminergic supraspinal mechanism
(Elsevier, 1994-04-25)
The role of dopaminergic descending supraspinal processes in mediating the antinociceptive action of cocaine was studied in the rat using a combination of extracellular neuronal recording and behavioral techniques. Neurons ...
