    Drywood termite feeding deterrents in sugar pine and antitermitic activity of related compounds (1983)
    Springer
    Journal of chemical ecology 9 (1983), S. 39-55 
    Details
    ISSN: 1573-1561
    Keywords: Feeding deterrents ; drywood termites ; Incisitermes minor ; Isoptera ; Kalotermitidae ; sugar pine ; Pinus lambertiana ; fatty acids α-halogenated acids ; esters
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The feeding deterrent activity of sapwood extracts of sugar pine,Pinus lambertiana Dougl., and related compounds was determined against immatures of the western drywood termite,Incisitermes minor (Hagen). A bioassay was designed to quantify reductions in termite feeding caused by deterrent chemicals. Crude extracts and isolated fractions of sugar pine were deterrent and not preferred byI. minor at 0.5 mg/cm2. Fatty acids occurring in sugar pine extracts had a broad range of deterrent activity. Long-chain saturated fatty acids were deterrent at 0.25 and 0.05 mg/cm2. Unsaturated or intermediate length (C8-C14) acids, many not found in sugar pine wood, were less active than long-chain saturated acids. Related alpha-halogenated compounds were highly deterrent at 0.05 mg/cm2 regardless of chain length or presence of a carboxylic acid moiety. Deposits of 2-iodooctadecanoic acid reduced termite feeding at 5 μg/cm2, while 2-bromooctadecanoic acid had deterrent activity comparable to commercial wood preservatives. None of the halogenated compounds tested were termiticidal.

    Identification of the defensive secretion from soldiers of the North American termite,Amitermes wheeleri (Desneux) (Isoptera: Termitidae) (1983)
    Springer
    Journal of chemical ecology 9 (1983), S. 1293-1305 
    Details
    ISSN: 1573-1561
    Keywords: Amitermes wheeleri ; Isoptera ; Termitidae ; termite soldiers ; defensive secretion ; ant repellents ; α-bisabolene ; β-bisabolene ; α2-bisabolene ; Iridomyrmex humilis ; Pogonomyrmex rugosus ; sesquiterpenes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Head capsule extracts ofAmitermes wheeleri soldiers yielded an isomeric mixture (67 μg/ soldier) of three sesquiterpene hydrocarbons identified by EIMS, [13C]-, and [1H]NMR as (+)-(S,Z)-α-bisabolene (53%), (+)-(R)-β-bisabolene (16%), and (−)-(Z)-α2-bisabolene (31%). When alarmed, the termite soldiers secreted the fluid onto the head surface surrounding the efferent pore of the frontal gland reservoir. A defensive function for the soldier secretion was indicated by the avoidance behavior displayed toward alarmed soldiers by the antagonistic ants,Pogonomyrmex rugosus andIridomyrmex humilis. Laboratory studies demonstrated that the sesquiterpene mixture is repellent to foragingI. humilis workers.

    Major human epididymis-specific gene product, HE3, is the first representative of a novel gene family (1994)
    New York, NY [u.a.] : Wiley-Blackwell

    Topics: Biology
    Notes: Differential screening of a human epididymal cDNA library led to the isolation and characterization of a major epididymis-specific cDNA clone family, referred to as HE3. More detailed sequence and PCR analysis identified two different but homologous gene transcripts, HE3α and HE3β. The former represents an mRNA of ca. 1 kb, encoding a putative small secretory polypeptide of 14903 MW. The HE3β transcript was only found as incomplete 3′ fragments. Analysis of human genomic DNA by Southern blotting suggested the presence in the human genome of at least three independent HE3-related genes. Isolation of genomic clones for the HE3α gene showed this to contain a single intron of 1.4 kb in the 5′ noncoding region. Although genomic clones corresponding to HE3β could not be found, a third highly homologous gene, HE3γ, was identified as a potential pseudogene. Neither nucleotide nor encoded amino acid sequences of the HE3 gene family are related to any other known sequence in the central databases, and thus represents a novel human gene family, with at least three nonallelic members. Northern hybridization analysis showed that HE3 gene products are specifically expressed in the human epididymis, and not in any other tissue examined. Furthermore, except for the pig, no other nonprimate species has been identified to express homologous sequences in the epididymis. RNase protection assays showed that both the HE3α and HE3β, but not the HE3γ genes, are expressed in the human epididymis. © 1994 Wiley-Liss, Inc.

    Structure and evolution of insulins: Implications for receptor binding (1992)

    Notes: Insulin is a member of a family of hormones, growth factors and neuropeptides which are found in both vertebrates and invertebrates. A common ‘insulin fold’ is probably adopted by all family members. Although the specificities of receptor binding are different, there is possibility of co-evolution of polypeptides and their receptors.

    A genomic regulatory network for development (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-03-02
    Description: Development of the body plan is controlled by large networks of regulatory genes. A gene regulatory network that controls the specification of endoderm and mesoderm in the sea urchin embryo is summarized here. The network was derived from large-scale perturbation analyses, in combination with computational methodologies, genomic data, cis-regulatory analysis, and molecular embryology. The network contains over 40 genes at present, and each node can be directly verified at the DNA sequence level by cis-regulatory analysis. Its architecture reveals specific and general aspects of development, such as how given cells generate their ordained fates in the embryo and why the process moves inexorably forward in developmental time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davidson, Eric H -- Rast, Jonathan P -- Oliveri, Paola -- Ransick, Andrew -- Calestani, Cristina -- Yuh, Chiou-Hwa -- Minokawa, Takuya -- Amore, Gabriele -- Hinman, Veronica -- Arenas-Mena, Cesar -- Otim, Ochan -- Brown, C Titus -- Livi, Carolina B -- Lee, Pei Yun -- Revilla, Roger -- Rust, Alistair G -- Pan, Zheng jun -- Schilstra, Maria J -- Clarke, Peter J C -- Arnone, Maria I -- Rowen, Lee -- Cameron, R Andrew -- McClay, David R -- Hood, Leroy -- Bolouri, Hamid -- GM-61005/GM/NIGMS NIH HHS/ -- HD-37105/HD/NICHD NIH HHS/ -- RR-06591/RR/NCRR NIH HHS/ -- RR-15044/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 1;295(5560):1669-78.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA. davidson@caltech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11872831" target="_blank"〉PubMed〈/a〉

    A great-appendage arthropod with a radial mouth from the Lower Devonian Hunsruck Slate, Germany (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-02-07
    Description: Great-appendage arthropods, characterized by a highly modified anterior limb, were previously unknown after the Middle Cambrian. One fossil from the Lower Devonian Hunsruck Slate, Germany, extends the stratigraphic range of these arthropods by approximately 100 million years. Schinderhannes bartelsi shows an unusual combination of anomalocaridid and euarthropod characters, including a highly specialized swimming appendage. A cladistic analysis indicates that the new taxon is basal to crown-group euarthropods and that the great-appendage arthropods are paraphyletic. This new fossil shows that features of the anomalocaridids, including the multisegmented raptorial appendage and circular plated mouth, persisted long after the initial radiation of the euarthropods.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuhl, Gabriele -- Briggs, Derek E G -- Rust, Jes -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):771-3. doi: 10.1126/science.1166586.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Palaeontology, Steinmann Institute, University of Bonn, Nussallee 8, 53115 Bonn, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197061" target="_blank"〉PubMed〈/a〉
