    Opiate peptide modulation of amino acid responses suggests novel form of neuronal communication (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-03-31
    Description: Mouse spinal neurons grown in tissue culture were used to study the electrophysiological pharmacology of the opiate peptide leucine-enkephalin. Enkephalin depressed glutamate-evoked responses in a noncompetitive manner independent of any other effects on membrane properties. The results demonstrate a neuromodulatory action of opiate peptide functionally distinct from the conventional neurotransmitter class of operation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barker, J L -- Neale, J H -- Smith, T G Jr -- Macdonald, R L -- New York, N.Y. -- Science. 1978 Mar 31;199(4336):1451-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/204016" target="_blank"〉PubMed〈/a〉

    Different actions of anticonvulsant and anesthetic barbiturates revealed by use of cultured mammalian neurons (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-05-19
    Description: Barbiturate anesthetics, but not anticonvulsants, abolish the spontaneous activity of cultured spinal cord neurons; directly increase membrane conductance, an effect which is suppressed by the gamma-aminobutyric acid (GABA) antagonists picrotoxin and penicillin; and are more potent than anticonvulsants in augmenting GABA and depressing glutamate responses. Barbiturate anticonvulsants abolish picrotoxin-induced convulsive activity. These results indicate qualitative and quantitative differences between anesthetic and anticonvulsant barbiturates, which may explain their different clinical effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Macdonald, R L -- Barker, J L -- New York, N.Y. -- Science. 1978 May 19;200(4343):775-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/205953" target="_blank"〉PubMed〈/a〉

    Inosine may be an endogenous ligand for benzodiazepine receptors on cultured spinal neurons (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-17
    Description: Mouse spinal neurons grown in tissue culture were used to study the membrane effects of the benzodiazepine flurazepam and the naturally occurring purine nucleoside inosine, which competes for benzodiazepine receptor sites in the central nervous system. Application of inosine elicited two types of transmitter-like membrane effects: a rapidly desensitizing excitatory response and a nondesensitizing inhibitory response. Flurazepam produced a similar excitatory response which showed cross-desensitization with the purine excitation. Flurazepam also blocked the inhibitory inosine response. The results provide electrophysiological evidence that an endogenous purine can activate two different conductances on spinal neurons and that flurazepam can activate one of the conductances and antagonize the other.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacDonald, J F -- Barker, J L -- Paul, S M -- Marangos, P J -- Skolnick, P -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):715-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/37602" target="_blank"〉PubMed〈/a〉

    Substance P: evidence for diverse roles in neuronal function from cultured mouse spinal neurons (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-28
    Description: Mouse spinal neurons grown in tissue culture were used to examine the membrane mechanisms of action of the peptide substance P. Two functionally distinct actions were observed, one being a rapidly desensitizing excitation, and the other being a dose-dependent, reversible depression of excitatory responses to the putative amino acid neurotransmitter glutamate. These effects on excitability suggest that substance P may play more than one role in intercellular communication in the nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vincent, J D -- Barker, J L -- New York, N.Y. -- Science. 1979 Sep 28;205(4413):1409-12.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224464" target="_blank"〉PubMed〈/a〉

    Enkephalin-containing neurons visualized in spinal cord cell cultures (1978)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1978-08-04
    Description: Neuronal cells, axons, and terminals containing immunoreactive enkephalin have been visualized in cultures of dissociated fetal spinal cord. These cultures may provide a valuable system in which to explore the effects of chronic drug treatment on the physiology of enkephalin-containing cells and their interactions with other cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neale, J H -- Barker, J L -- Uhl, G R -- Snyder, S H -- New York, N.Y. -- Science. 1978 Aug 4;201(4354):467-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/351811" target="_blank"〉PubMed〈/a〉

    LANDSAT digital data processing: A near real-time application (1975)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: An application of rapid generation of classed digital images from LANDSAT-1 was demonstrated and its feasibility evaluated by NASA in conjunction with the Environmental Protection Agency (EPA), Texas A and M University (TAMU), and the Cousteau Society. The primary purpose was to show that satellite data could be processed and transmitted to the Calypso, which was used as a research vessel, in time for use in directing it to specific locations of possible plankton upwellings, sediment, or other anomalies in the coastal water areas along the Gulf of Mexico.

    LANDSAT-1 data as it has been applied for land use and water quality data by the Virginia State Water Control Board. 1: The state project. 2: Monitoring water quality from LANDSAT (1975)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: LANDSAT-1 imagery has been used for water quality and land use monitoring in and around the Swift Creek and Lake Chesdin Reservoirs in Virginia. This has proved useful by (1) helping determine valid reservoir sampling stations, (2) monitoring areas not accessible by land or water, (3) giving the State a viable means of measuring Secchi depth readings in these inaccessible areas, (4) giving an overview of trends in changing sedimentation loadings over a given time period and classifying these waters into various categories, (5) enabling the State to inventory all major lakes and reservoirs and computing their acreage, (6) monitoring land use changes in any specific area, (7) evaluating possible long-term environmental effects of nearby developments, and (8) monitoring and predicting population shifts with possible impact on water quality problems. The main problems in the long-term use of such imagery appear to be cost and lack of consistency due to cloud cover limitations.

    Monitoring water quality from LANDSAT (1975)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: Water quality monitoring possibilities from LANDSAT were demonstrated both for direct readings of reflectances from the water and indirect monitoring of changes in use of land surrounding Swift Creek Reservoir in a joint project with the Virginia State Water Control Board and NASA. Film products were shown to have insufficient resolution and all work was done by digitally processing computer compatible tapes. Land cover maps of the 18,000 hectare Swift Creek Reservoir watershed, prepared for two dates in 1974, are shown. A significant decrease in the pine cover was observed in a 740 hectare construction site within the watershed. A measure of the accuracy of classification was obtained by comparing the LANDSAT results with visual classification at five sites on a U-2 photograph. Such changes in land cover can alert personnel to watch for potential changes in water quality.
