    Notes: Summary The rostral pars distalis (RPD) of the teleost Mugil platanus from animals pretreated with reserpine or 6-hydroxydopamine (6-HODA) were assayed for dopamine (DA) or noradrenaline (NA) or for prolactin hormone. Such determinations were coupled with electron microscopy. It was found that reserpine and 6-HODA produced a significant decrease in the content of DA, NA, and prolactin. Electron microscope studies revealed that prolactin cells became activated as judged by ultrastructural criteria. After 6-HODA treatment type “B” neurosecretory fibers entering the RPD became selectively destroyed. These observations lead us to suggest that prolactin secretion is under inhibitory control by type “B” neurosecretory fibers of adrenergic nature.

    Description: Sex pheromones isolated from the cuticle of the female tsetse fly, Glossina morsitans morsitans Westwood, release mating behavior in the male fly at ultrashort range or upon contact with baited decoys. Three active components were identified as 15,19-dimethylheptatriacontane, 17,21-dimethylheptatriacontane, and 15,19,23-trimethylheptatriacontane. Chemical and biological comparisons show that the natural and synthetic compounds are identical.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlson, D A -- Langley, P A -- Huyton, P -- New York, N.Y. -- Science. 1978 Aug 25;201(4357):750-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/675256" target="_blank"〉PubMed〈/a〉

    Description: Incubation of minced mouse-forebrain tissues in lithium Krebs solution reduces the acetylcholine content of the vesicular fraction 70 percent without altering that of the cytoplasmic fraction. Depleted vesicular-bound acetylcholine can be restored with newly synthesized acetylcholine (formed from extracellular choline) independently of the cytoplasmic pool. Depletion of vesicular-bound acetylcholine does not facilitate the movement of preformed extracellular acetylcholine into vesicles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carrol, P T -- Nelson, S H -- New York, N.Y. -- Science. 1978 Jan 6;199(4324):85-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Toxicology, University of Rhode Island, Kingston, RI 02881, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17569492" target="_blank"〉PubMed〈/a〉

    Description: Long-term habituation training in Aplysia californica produces a profound depression in the efficacy of synaptic transmission between mechanoreceptor neurons and gill motor neurons. This depression persists for more than 3 weeks. Thus a critical synaptic site for plasticity underlying long-term habituation is the same as that for short-term habituation. For this simple form of learning, short- and long-term memory share a common locus and aspects of a common mechanism: synaptic depression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Castellucci, V F -- Carew, T J -- Kandel, E R -- New York, N.Y. -- Science. 1978 Dec 22;202(4374):1306-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/214854" target="_blank"〉PubMed〈/a〉

    Description: Sulfhydryl reagents exert a profound influence on the monodeiodination of thyroxine to triiodothyronine by rat and sheep tissues in vitro. A marked dithiothreitol-induced increase in the monodeiodination by fetal sheep liver homogenates suggests that the characteristically low conversion in fetal tissues is related more to the status of sulfhydryl groups than to a deficiency of the monodeiodinating enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chopra, I J -- New York, N.Y. -- Science. 1978 Feb 24;199(4331):904-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622575" target="_blank"〉PubMed〈/a〉

    Description: The body shapes of humans and chimpanzees were compared quantitatively by criteria chosen for their capacity to discriminate well among the body shapes of frogs. By these criteria, the difference in body shape between humans and chimpanzees was found to be greater than that between the most dissimilar pairs of frogs examined--that is, frogs classified in separate taxonomic suborders. Even though the morphological diffference between the two primates is large by frog standards, the biochemical differences between the structural genes of these two species are small. The results of this study give quantitative support to the proposal that morphological evolution and biochemical evolution in structural genes can proceed at independent rates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cherty, L M -- Case, S M -- Wilson, A C -- New York, N.Y. -- Science. 1978 Apr 14;200(4338):209-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/635583" target="_blank"〉PubMed〈/a〉

    Description: Brains of juvenile gray bats, Myotis grisescens, found dead beneath maternity roosts in two Missouri caves contained lethal concentrations of dieldrin. One colony appeared to be abnormally small, and more dead bats were found a year after the juvenile bats had been collected. This is the first report to link the field mortality of bats directly to insecticide residues acquired through the food chain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clark, D R Jr -- LaVal, R K -- Swineford, D M -- New York, N.Y. -- Science. 1978 Mar 24;199(4335):1357-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/564550" target="_blank"〉PubMed〈/a〉
