    Description / Table of Contents: Zusammenfassung Das Sexualverhalten männlicher Falter des Pfirsichtriebwicklers, Grapholitha molesta (Busck), gegenüber verschiedenen Dosierungen und Mischungen von (Z)-8- und (E)-8-Dodecenylacetat wurde untersucht. Ein stetiger Aufwindflug, der zum Auffinden der Duftquelle führte, konnte nur im mittleren Dosierungs- und Mischungsbereich beobachtet werden. Ausserhalb dieses Optimums war die Dosierung offenbar entweder zu hoch oder zu niedrig, um eine deutliche Anlockung, d.h. einen gerichteten Flug innerhalb der Duftfahne zu bewirken; bei hoher Konzentration näherten sich die Tiere der Quelle nur auf bestimmte Distanz (arrestment). Freilandversuche mit Fallen führten zu ähnlichen Ergebnissen, nur dass dort das Dosierungsoptimum bei ca. zehnmal höheren Werten lag als in den Versuchen im Windkanal. Der bei hohen Mengen an E-Isomer (hohe Dosis oder hohes E/Z-verhältnis) beobachtete Arrestment-Effekt könnte auf Erhöhung der Drehbewegungen oder Verringerung der Fluggeschwindigkeit zurückzuführen sein.
    Notes: Abstract The sex pheromone-mediated responses of male oriental fruit moths, Grapholitha molesta (Busck), to an array of blends and dosages of Z8-12Ac and E8-12:Ac, were analyzed. Males exhibited sustained upwind flight resulting in source location only to intermediate blends and dosages. This optimal range of treatments appeared to be bounded by dosages too low or too high to result in significant attraction (net within-plume displacement toward the source), the higher concentrations causing arrestment (no net within-plume displacement) at some distance from the source. Similar results were obtained in field-trapping studies with the same treatments, except that the optimal dosages were moved up about 10-fold. Increased turning and decreased linear velocity could account for arrestment with increasing amounts of the (E) isomer in high dosages and high (E)/(Z) ratio blends.

    Oriental fruit moth pheromone component emission rates measured after collection by glass-surface adsorption (1980)
    Springer
    Journal of chemical ecology 6 (1980), S. 749-758 
    Details
    ISSN: 1573-1561
    Keywords: Oriental fruit moth ; Grapholitha molesta ; pheromone release rate ; airborne collection ; (Z)-8-dodecenyl acetate ; (Z)-8-dodecenyl alcohol
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract We collected and quantified both synthetic and natural Oriental fruit moth [Grapholitha molesta (Busck)] sex pheromone components in 250-ml round-bottom flasks by hexane rinsing of compounds adsorbed on the glass walls. This simple procedure collected 100% of the pheromone evaporated inside the flask and was useful for quantifying both nanogram and microgram amounts of emitted pheromone. Emission rates of (Z)-8-dodecenyl acetate from 1000, 100, and 10 μg-loaded rubber septa were 219, 12, and 1.2 ng/hr, respectively.G. molesta females emitted this component at 3.2 ng/hr, close to the emission rate from a 10 μg-loaded septum, which evokes “long-range” and “close-range” behaviors in the male. The corresponding alcohol, (Z)-8-dodecenyl alcohol, was emitted from rubber septa ca. 3 times faster than the acetate.

    Two classes of single-stranded regions in DNA from sea urchin embryos (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-02-06
    Description: Native DNA from sea urchin embryos contains single-stranded regions (gaps) of up to 3000 nucleotides. The longer gaps (more than 1400 nucleotides) are nonrandomly distributed and are rich in histone gene sequences, other moderately repetitive sequences, and polypyrimidines. The shorter gaps are associated with DNA replication. A method for isolation of the two classes of single-stranded DNA pieces is reported.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wortzman, M S -- Baker, R F -- New York, N.Y. -- Science. 1981 Feb 6;211(4482):588-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455698" target="_blank"〉PubMed〈/a〉

    Adaptive changes of the vestibulo-ocular reflex in flatfish are achieved by reorganization of central nervous pathways (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-08-19
    Description: Flatfish provide a natural model for the study of adaptive changes in the vestibulo-ocular reflex system. During metamorphosis their vestibular and oculomotor coordinate systems undergo a 90 degree relative displacement. As a result, during swimming movements different types of compensatory eye movements are produced before and after metamorphosis by the same vestibular stimulation. Intracellular staining of central nervous connections in the flatfish with horseradish peroxidase revealed that in postmetamorphic fish secondary horizontal semicircular canal neurons contact vertical eye muscle motoneuron pools on both sides of the brain via pathways that are absent in all other vertebrates studied.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graf, W -- Baker, R -- 13742/PHS HHS/ -- New York, N.Y. -- Science. 1983 Aug 19;221(4612):777-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6603656" target="_blank"〉PubMed〈/a〉

    Narcolepsy: biogenic amine deficits in an animal model (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-06
    Description: Concentrations of biogenic amine metabolites in discrete brain areas differed significantly between dogs with genetically transmitted narcolepsy and age- and breed-matched controls. Dopamine and 3,4-dihydroxyphenylacetic acid were consistently elevated in the brains of narcoleptic animals, while homovanillic acid was not. Narcoleptic animals consistently exhibited lower utilization of dopamine and higher intraneuronal degradation of dopamine but no uniform decrease in serotonin utilization. Hence neuropathology appears to be associated with genetically transmitted canine narcolepsy. The data indicate a nonglobal depression of dopamine utilization or turnover or both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mefford, I N -- Baker, T L -- Boehme, R -- Foutz, A S -- Ciaranello, R D -- Barchas, J D -- Dement, W C -- MH 05804/MH/NIMH NIH HHS/ -- MH 23861/MH/NIMH NIH HHS/ -- NS 13211/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 May 6;220(4597):629-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6188216" target="_blank"〉PubMed〈/a〉

    Mass mortality of harbor seals: pneumonia associated with influenza A virus (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-26
    Description: More than 400 harbor seals, most of them immature, died along the New England coast between December 1979 and October 1980 of acute pneumonia associated with influenza virus, A/Seal/Mass/1/180 (H7N7). The virus has avian characteristics, replicates principally in mammals, and causes mild respiratory disease in experimentally infected seals. Concurrent infection with a previously undescribed mycoplasma or adverse environmental conditions may have triggered the epizootic. The similarities between this epizootic and other seal mortalities in the past suggest that these events may be linked by common biological and environmental factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geraci, J R -- St Aubin, D J -- Barker, I K -- Webster, R G -- Hinshaw, V S -- Bean, W J -- Ruhnke, H L -- Prescott, J H -- Early, G -- Baker, A S -- Madoff, S -- Schooley, R T -- AI02649/AI/NIAID NIH HHS/ -- AI16841/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 26;215(4536):1129-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063847" target="_blank"〉PubMed〈/a〉

    Diphenylhydantoin: an alternative ligand of a glucocorticoid receptor affecting prostaglandin generation in A/J mice (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: Evidence for the binding of 5,5-diphenylhydantoin and glucocorticoids to a common receptor is presented for pulmonary and hepatic cytosols and thymocytes of A/J female mice. The 5,5-diphenylhydantoin-protein complex is absorbed by DNA cellulose, and is incorporated into nuclei, 5,5-Diphenylhydantoin, like glucocorticoids, inhibits the production of prostaglandins in thymocytes. Thus a common receptor is probably responsible for the inhibitory and teratogenic effects of these drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Katsumata, M -- Gupta, C -- Baker, M K -- Sussdorf, C E -- Goldman, A S -- DE-4622/DE/NIDCR NIH HHS/ -- DE-5041/DE/NIDCR NIH HHS/ -- DE-5592/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1313-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6897299" target="_blank"〉PubMed〈/a〉

    A gene controlling condensation of heterochromatin in Drosophila melanogaster (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-07-01
    Description: A temperature-sensitive lethal mutant of Drosophila melanogaster was used to identify an essential cell cycle function that is necessary for the mitotic condensation of heterochromatic but not of euchromatic portions of the genome. This mutant is an allele at a locus (mus-101) identified earlier by the use of mutagen-sensitive mutants. The data suggest that the mutagen-sensitive and repair-defective phenotypes of viable mus-101 mutants result from a disruption in chromosome organization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gatti, M -- Smith, D A -- Baker, B S -- GM23345/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 1;221(4605):83-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6407113" target="_blank"〉PubMed〈/a〉
