    Beschreibung: The Interdisciplinary Panel on Carcinogenicity reviewed and reevaluated criteria for assessing evidence of carcinogenicity of chemical substances. The panel reviewed criteria applicable to data derived from human epidemiological studies and from both in vivo and in vitro laboratory studies. A critical appraisal of all these sources of information led to the conclusion that the characterization of human risk always requires interdisciplinary evaluation of the entire array of data on a case-by-case basis. Animal studies, whenever possible, should be augmented by studies of mechanisms, metabolism, and pharmacodynamics. Such studies may assist in assessing risk to man. Recognizing the utility of such data should point the way for better assessment in the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉New York, N.Y. -- Science. 1984 Aug 17;225(4663):682-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6463646" target="_blank"〉PubMed〈/a〉

    Beschreibung: Recent advances in biotechnology have created many public policy and legal issues, one of the most significant of which is the treatment of biotechnological industrial products, particularly under the patent system. Patents represent one of several types of intellectual property; their ownership confers the right to exclude others from benefitting from the tangible products of a proprietary subject matter. Intellectual property law and its protections will play a major role in the rate at which biotechnology develops in the United States. In this article biotechnological intellectual property issues are reviewed in the context of their underlying legal requirements. The implications of other factors, such as international competition, research funding, and gene ownership, are also considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adler, R G -- New York, N.Y. -- Science. 1984 Apr 27;224(4647):357-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6584975" target="_blank"〉PubMed〈/a〉

    Beschreibung: The iron-carbon monoxide stretching mode and the iron-carbon-oxygen bending mode in carbon monoxide-bound cytochrome oxidase have been assigned at 520 and 578 cm-1, respectively. The frequencies, widths, and intensities of these modes show that the Fe-C-O grouping in carbon monoxide-cytochrome a3 is linear but tilted from the normal to the heme plane; that the iron-histidine bond in both five- and six-coordinate cytochrome a3 is strained; and that the carbon monoxide and the proximal histidine each have characteristic, well-defined orientations in all molecules. These data can account for the binding affinities of carbon monoxide and dioxygen under physiological conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Argade, P V -- Ching, Y C -- Rousseau, D L -- New York, N.Y. -- Science. 1984 Jul 20;225(4659):329-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6330890" target="_blank"〉PubMed〈/a〉

    Beschreibung: A T lymphotropic virus found in patients with the acquired immune deficiency syndrome (AIDS) or lymphadenopathy syndrome has been postulated to be the cause of AIDS. Immunological analysis of this retrovirus and its biological properties suggest that it is a member of the family of human T-lymphotropic retroviruses known as HTLV. Accordingly, it has been named HTLV-III. In the present report it is shown by nucleic acid hybridization that sequences of the genome of HTLV-III are homologous to the structural genes (gag, pol, and env) of both HTLV-I and HTLV-II and to a potential coding region called pX located between the env gene and the long terminal repeating sequence that is unique to the HTLV family of retroviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arya, S K -- Gallo, R C -- Hahn, B H -- Shaw, G M -- Popovic, M -- Salahuddin, S Z -- Wong-Staal, F -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):927-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089333" target="_blank"〉PubMed〈/a〉

    Beschreibung: A complementary DNA probe corresponding to the beta-chain gene of Ti, the human T lymphocyte receptor, has been molecularly cloned. The chromosomal origin of the Ti beta gene was determined with the complementary DNA by screening a series of 12 cell hybrid (mouse X human) DNA's containing overlapping subsets of human chromosomes. DNA hybridization (Southern) experiments showed that the human Ti beta gene resides on chromosome 7 and is thus not linked to the immunoglobulin loci or to the major histocompatibility locus in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barker, P E -- Ruddle, F H -- Royer, H D -- Acuto, O -- Reinherz, E L -- AI 21226/AI/NIAID NIH HHS/ -- GM-09966/GM/NIGMS NIH HHS/ -- R0 1 AI 19807/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Oct 19;226(4672):348-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6435246" target="_blank"〉PubMed〈/a〉

    Beschreibung: The immune response genes of the mouse encode two cell-surface glycoproteins, I-A and I-E, that play critical roles in determining the animal's immune responsiveness. The I-A antigen contains two chains, alpha and beta. A cloned beta-chain gene, I-A beta k, was introduced into B-lymphoma cells that express I-Ad. The transfected gene was successfully expressed on the cell surface of the recipient cells and was functional in stimulating allospecific T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ben-Nun, A -- Glimcher, L H -- Weis, J -- Seidman, J G -- AI18436/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Feb 24;223(4638):825-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6420890" target="_blank"〉PubMed〈/a〉

    Beschreibung: Bromodeoxyuridine (BrdUrd) treatment of the prolactin nonproducing subclone of GH cells (rat pituitary tumor cells) induces amplification of a 20-kilobase DNA fragment including all of the prolactin gene coding sequences. This amplified DNA segment, which is flanked by two unamplified regions, thus designates a unit of BrdUrd-induced amplified sequence. Cloned DNA segments, 10.3 kilobases long, from the 5' end of the rat prolactin gene of BrdUrd-responsive and -nonresponsive cells, were ligated to the thymidine kinase gene of herpes simplex virus type 1 (HSV1TK), and the hybrid DNA was transferred to thymidine kinase-deficient mouse fibroblast cells by transfection. The HSV1TK gene and the rat prolactin gene were amplified together in drug-treated transfectants carrying the hybrid DNA HSV1TK gene and rat prolactin gene of BrdUrd-responsive GH cells. These results suggest that the 10.3-kilobase DNA segment at the 5' end of the rat prolactin gene of BrdUrd-responsive GH cells carries the information for drug-induced gene amplification (amplicon) and that another gene, such as the HSV1TK gene, is also amplified when the latter is placed adjacent to this segment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biswas, D K -- Hartigan, J A -- Pichler, M H -- CA28218/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):941-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089335" target="_blank"〉PubMed〈/a〉

    Beschreibung: The genome of the small human virus serologically associated with erythrocyte aplasia and erythema infectiosum (fifth disease) is shown to be a linear, nonpermuted, single-stranded DNA molecule with self-priming hairpin termini, properties which are characteristic of the genomes of the family Parvoviridae. This human parvovirus chromosome was molecularly cloned into bacterial plasmid vectors and the cloned DNA was used to explore its relatedness to other mammalian parvovirus serotypes by DNA:DNA hybridization. It is not related to the human adeno-associated viruses but does show a distant evolutionary relationship to genomes of the helper-independent parvoviruses of rodents. This strongly suggests that it is an autonomous parvovirus, and as such is the first example of a member of this group of common animal pathogens to cause disease in man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cotmore, S F -- Tattersall, P -- CA29303/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Dec 7;226(4679):1161-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6095448" target="_blank"〉PubMed〈/a〉

The untranslated 3' end of this complementary DNA is homologous to two RNA transcripts present in postmeiotic cells of the testis but absent from meiotic cells and from several tissues including brain.

    Beschreibung: Fourier transform mass spectrometry will play an important role in the future because of its unique combination of high mass resolution, high upper mass limit, and multichannel advantage. These features have already found application in gas chromatography-mass spectrometry, multiphoton ionization, laser desorption, and secondary ion mass spectrometry. However, its most notable feature is the ability to store ions. This characteristic, when combined with the others, will allow expeditious study of the interaction of gas-phase ions with both photons (photodissociation) and neutral molecules, and the convenient application of this fundamental information for chemical analysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gross, M L -- Rempel, D L -- 2-8423576/PHS HHS/ -- New York, N.Y. -- Science. 1984 Oct 19;226(4672):261-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6385250" target="_blank"〉PubMed〈/a〉

    Beschreibung: In order to further define the mechanisms by which polypeptide growth factors regulate gene transcription and cellular growth, expression cloning techniques were used to select human epidermal growth factor (EGF) receptor complementary DNA clones. The EGF 3' coding domain shows striking homology to the transforming gene product of avian erythroblastosis virus (v-erbB). Over-expression of EGF receptors in A431 cell lines correlates with increased EGF receptor mRNA levels and amplification (up to 110 times) of the apparently singular EGF receptor gene. There appear to be three cytoplasmic polyadenylated RNA products of EGF receptor gene expression in A431 cells, one of which contains only 5' (EGF binding domain) sequences and is postulated to encode the secreted EGF receptor-related protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, C R -- Chen, W S -- Kruiger, W -- Stolarsky, L S -- Weber, W -- Evans, R M -- Verma, I M -- Gill, G N -- Rosenfeld, M G -- New York, N.Y. -- Science. 1984 May 25;224(4651):843-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6326261" target="_blank"〉PubMed〈/a〉

    Beschreibung: High-resolution carbon-13 nuclear magnetic resonance (NMR) spectra of enzyme-inhibitor and enzyme-substrate complexes provide detailed structural and stereochemical information on the mechanism of enzyme action. The proteases trypsin and papain are shown to form tetrahedrally coordinated complexes and acyl derivatives with a variety of compounds artificially enriched at the site or sites of interest. These results are compared with the structural information derived from x-ray diffraction. Detailed NMR studies have provided a clearer picture of the ionization state of the residues participating in enzyme-catalyzed processes than other more classical techniques. The dynamics of enzymic catalysis can be observed at sub-zero temperatures by a combination of cryoenzymology and carbon-13 NMR spectroscopy. With these powerful techniques, transient, covalently bound intermediates in enzyme-catalyzed reactions can be detected and their structures rigorously assigned.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mackenzie, N E -- Malthouse, J P -- Scott, A I -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):883-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6433481" target="_blank"〉PubMed〈/a〉

    Beschreibung: The splicing of messenger RNA precursors in vitro proceeds through an intermediate that has the 5' end of the intervening sequence joined to a site near the 3' splice site. This lariat structure, which has been characterized for an adenovirus 2 major late transcript, has a branch point, with 2'-5' and 3'-5' phosphodiester bonds emanating from a single adenosine residue. The excised intervening sequence retains the branch site and terminates in a guanosine residue with a 3' hydroxyl group. The phosphate group at the splice junction between the two exons originates from the 3' splice site at the precursor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Padgett, R A -- Konarska, M M -- Grabowski, P J -- Hardy, S F -- Sharp, P A -- P01-CA14051/CA/NCI NIH HHS/ -- P01-CA26717/CA/NCI NIH HHS/ -- R01-GM32467/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):898-903.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6206566" target="_blank"〉PubMed〈/a〉

    Beschreibung: Interferon-beta 1 (IFN-beta 1) complementary DNA was used as a hybridization probe to isolate human genomic DNA clones lambda B3 and lambda B4 from a human genomic DNA library. Blot-hybridization procedures and partial nucleotide sequencing revealed that lambda B3 is related to IFN-beta 1 (and more distantly to IFN-alpha 1). Analyses of DNA obtained from a panel of human-rodent somatic cell hybrids that were probed with DNA derived from lambda B3 showed that lambda B3 is on human chromosome 2. Similar experiments indicated that lambda B4 is not on human chromosomes 2, 5, or 9. The finding that DNA related to the IFN-beta 1 gene (and IFN-alpha 1 gene) is dispersed in the human genome raises new questions about the origins of the interferon genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sagar, A D -- Sehgal, P B -- May, L T -- Inouye, M -- Slate, D L -- Shulman, L -- Ruddle, F H -- AI-16262/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Mar 23;223(4642):1312-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6546621" target="_blank"〉PubMed〈/a〉

    Beschreibung: Although most medical educators believe that education, research, and patient care are inseparable and essential to their academic mission, the educational component of this triad has never been given adequate, earmarked support. To fund educational programs, medical centers first relied on research grants and later on third-party payments intended for patient care. However, research money has long since ceased to be available for other purposes and recent federal cost containment measures have started to reduce payments for patient care. Teaching hospitals are threatened with loss of support not only for education, but for their capital improvements and care of the poor. Many institutions are now hoping to generate new income through business deals with for-profit health care corporations, but this effort probably will also fail and may compromise professional traditions. Teaching hospitals serve the public interest and will have to depend, at least in part, on public subsidy of their unavoidable extra costs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Relman, A S -- New York, N.Y. -- Science. 1984 Oct 5;226(4670):20-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6382612" target="_blank"〉PubMed〈/a〉

    Beschreibung: On the basis of an analysis of the human and rat calcitonin genes and of a related gene, alternative RNA processing represents a developmental strategy of the brain to dictate tissue-specific patterns of polypeptide synthesis. This regulation allows the calcitonin gene to generate two messenger RNA's, one encoding the precursor of a novel neuropeptide, referred to as CGRP, which predominates in the brain, and the second encoding the precursor to the hormone calcitonin which predominates in thyroid C cells. The distribution of CGRP in the central and peripheral nervous system and in endocrine and other organ systems suggests potential functions in nociception, ingestive behavior, cardiovascular homeostasis, and mineral metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenfeld, M G -- Amara, S G -- Evans, R M -- New York, N.Y. -- Science. 1984 Sep 21;225(4668):1315-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089345" target="_blank"〉PubMed〈/a〉

    Beschreibung: The Aplysia neuroendocrine system is a particularly advantageous model for cellular and molecular studies because of the relatively small number and large size of its component neurons. Recombinant DNA techniques have been used to isolate the genes that encode the precursors of peptides expressed in identified neurons of known function. The organization and developmental expression of these genes have been examined in detail. Several of the genes encode precursors of multiple biologically active peptides that are expressed in cells which also contain classical transmitters. These studies, as well as immunohistochemical studies and the use of intracellular recording and voltage clamp techniques are the first steps toward revealing the mechanisms by which neuropeptides govern simple behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheller, R H -- Kaldany, R R -- Kreiner, T -- Mahon, A C -- Nambu, J R -- Schaefer, M -- Taussig, R -- New York, N.Y. -- Science. 1984 Sep 21;225(4668):1300-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6474178" target="_blank"〉PubMed〈/a〉

    Beschreibung: The human T-cell leukemia (lymphotropic) virus type III (HTLV-III) appears to be central to the causation of the acquired immune deficiency syndrome (AIDS). Two full-length integrated proviral DNA forms of HTLV-III have now been cloned and analyzed, and DNA sequences of the virus in cell lines and fresh tissues from patients with AIDS or AIDS-related complex (ARC) have been characterized. The results revealed that (i) HTLV-III is an exogenous human retrovirus, approximately 10 kilobases in length, that lacks nucleic acid sequences derived from normal human DNA; (ii) HTLV-III, unlike HTLV types I and II, shows substantial diversity in its genomic restriction enzyme cleavage pattern; (iii) HTLV-III persists in substantial amounts in cells as unintegrated linear DNA, an uncommon property that has been linked to the cytopathic effects of certain animal retroviruses; and (iv) HTLV-III viral DNA can be detected in low levels in fresh (primary) lymphoid tissue of a minority of patients with AIDS or ARC but appears not to be present in Kaposi's sarcoma tissue. These findings have important implications concerning the biological properties of HTLV-III and the pathophysiology of AIDS and Kaposi's sarcoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shaw, G M -- Hahn, B H -- Arya, S K -- Groopman, J E -- Gallo, R C -- Wong-Staal, F -- New York, N.Y. -- Science. 1984 Dec 7;226(4679):1165-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6095449" target="_blank"〉PubMed〈/a〉

    Beschreibung: The mechanism of lipid peroxidation and the manner in which antioxidants function is reviewed. beta-Carotene is a purported anticancer agent, which is believed by some to have antioxidant action of a radical-trapping type. However, definitive experimental support for such action has been lacking. New experiments in vitro show that beta-carotene belongs to a previously unknown class of biological antioxidants. Specifically, it exhibits good radical-trapping antioxidant behavior only at partial pressures of oxygen significantly less than 150 torr, the pressure of oxygen in normal air. Such low oxygen partial pressures are found in most tissues under physiological conditions. At higher oxygen pressures, beta-carotene loses its antioxidant activity and shows an autocatalytic, prooxidant effect, particularly at relatively high concentrations. Similar oxygen-pressure-dependent behavior may be shown by other compounds containing many conjugated double bonds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burton, G W -- Ingold, K U -- New York, N.Y. -- Science. 1984 May 11;224(4649):569-73.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6710156" target="_blank"〉PubMed〈/a〉

    Beschreibung: The nicotine receptor for the neurotransmitter acetylcholine is an allosteric protein composed of four different subunits assembled in a transmembrane pentamer alpha 2 beta gamma delta. The protein carries two acetylcholine sites at the level of the alpha subunits and contains the ion channel. The complete sequence of the four subunits is known. The membrane-bound protein undergoes conformational transitions that regulate the opening of the ion channel and are affected by various categories of pharmacologically active ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Changeux, J P -- Devillers-Thiery, A -- Chemouilli, P -- New York, N.Y. -- Science. 1984 Sep 21;225(4668):1335-45.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6382611" target="_blank"〉PubMed〈/a〉

    Beschreibung: The genetic relationships among molecularly cloned prototype viruses representing all of the major oncovirus genera were investigated by molecular hybridization and nucleotide sequence analysis. One of the major progenitors of the pol genes of such viruses gives rise to mammalian type C viruses and another gives rise to type A, B, D, and avian type C oncoviruses. Evidence of unusual patterns of homology among the env genes of mammalian type C and D oncoviruses illustrates that genetic interactions between their progenitors contributed to the evolution of oncoviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chiu, I M -- Callahan, R -- Tronick, S R -- Schlom, J -- Aaronson, S A -- New York, N.Y. -- Science. 1984 Jan 27;223(4634):364-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6197754" target="_blank"〉PubMed〈/a〉

The activated mouse N-ras gene was isolated from one of these lymphomas and, by transformation in concert with restriction digestion, a map of the gene was prepared and its approximate boundaries were determined. By means of somatic cell hybrids the normal N-ras gene was found to be unlinked to other members of the ras gene family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guerrero, I -- Villasante, A -- D'Eustachio, P -- Pellicer, A -- CA-16239/CA/NCI NIH HHS/ -- GM-32105/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Sep 7;225(4666):1041-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089339" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mouse tumors induced by gamma radiation are a useful model system for oncogenesis. DNA from such tumors contains an activated K-ras oncogene that can transform NIH 3T3 cells. This report describes the cloning of a fragment of the mouse K-ras oncogene containing the first exon from both a transformant in rat-2 cells and the brain of the same mouse that developed the tumor. Hybrid constructs containing one of the two pieces were made and only the plasmid including the first exon from the transformant gave rise to foci in NIH 3T3 cells. There was only a single base difference (G----A) in the exonic sequence, which changed glycine to aspartic acid in the transformant. By use of a synthetic oligonucleotide the presence of the mutation was demonstrated in the original tumor, ruling out modifications during DNA-mediated gene transfer and indicating that the alteration was present in the thymic lymphoma but absent from other nonmalignant tissue. The results are compatible with gamma radiation being a source of point mutations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guerrero, I -- Villasante, A -- Corces, V -- Pellicer, A -- CA-36327/CA/NCI NIH HHS/ -- GM-32036/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Sep 14;225(4667):1159-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6474169" target="_blank"〉PubMed〈/a〉

    Beschreibung: Yeast phenylalanine transfer RNA was subjected to a 12-picosecond molecular dynamics simulation. The principal features of the x-ray crystallographic analysis are reproduced, and the amplitudes of atomic displacements appear to be determined by the degree of exposure of the atoms. An analysis of the hydrogen bonds shows a correlation between the average length of a bond and the fluctuation in that length and reveals a rocking motion of bases in Watson-Crick guanine X cytosine base pairs. The in-plane motions of the bases are generally of larger amplitude than the out-of-plane motions, and there are correlations in the motions of adjacent bases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harvey, S C -- Prabhakaran, M -- Mao, B -- McCammon, J A -- New York, N.Y. -- Science. 1984 Mar 16;223(4641):1189-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6560785" target="_blank"〉PubMed〈/a〉

    Beschreibung: The importance and origin of antimicrobial-resistant Salmonella infections were examined in 52 outbreaks investigated by the Centers for Disease Control between 1971 and 1983. The case fatality rate was higher for patients infected with antimicrobial-resistant Salmonella (4.2 percent) than for those with antimicrobial-sensitive infections (0.2 percent). In the 38 outbreaks with identified sources, food animals were the source of 11 (69 percent) of 16 resistant and 6 (46 percent) of 13 sensitive outbreak strains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holmberg, S D -- Wells, J G -- Cohen, M L -- New York, N.Y. -- Science. 1984 Aug 24;225(4664):833-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6382605" target="_blank"〉PubMed〈/a〉

    Beschreibung: Most mitochondrial proteins are encoded in the nucleus and are translated on free cytoplasmic ribosomes as larger precursors containing amino-terminal "leader" sequences, which are removed after the precursors are taken up by mitochondria. We have deduced the complete primary structure of the precursor of a human mitochondrial matrix enzyme, ornithine transcarbamylase (OTC), from the nucleotide sequence of cloned complementary DNA. The amino-terminal leader peptide of OTC is 32 amino acids in length and contains four arginines but no acidic residues. Cleavage of the leader peptide from the "mature" protein occurs between glutamine and asparagine residues. The sequence of mature human OTC resembles that of the subunits of both OTC and aspartate transcarbamylase from Escherichia coli. The biological activity of the cloned OTC complementary DNA was tested by joining it with SV40 (an animal virus) regulatory elements and transfecting cultured HeLa cells, which do not normally express OTC. Both the precursor and mature forms of the OTC subunit were identified; in stable transformants, enzymatic activity was also detected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horwich, A L -- Fenton, W A -- Williams, K R -- Kalousek, F -- Kraus, J P -- Doolittle, R F -- Konigsberg, W -- Rosenberg, L E -- AM 09527/AM/NIADDK NIH HHS/ -- AM 12579/AM/NIADDK NIH HHS/ -- GM 31539/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1984 Jun 8;224(4653):1068-74.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6372096" target="_blank"〉PubMed〈/a〉

    Beschreibung: Sequence-dependent variations in DNA revealed by x-ray crystallographic studies have suggested that certain DNA-reactive drugs may react preferentially with defined sequences in DNA. Drugs that wind around the helix and reside within one of the grooves of DNA have perhaps the greatest chance of recognizing sequence-dependent features of DNA. The antitumor antibiotic CC-1065 covalently binds through N-3 of adenine and resides within the minor groove of DNA. This drug overlaps with five base pairs for which a high sequence specificity exists.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hurley, L H -- Reynolds, V L -- Swenson, D H -- Petzold, G L -- Scahill, T A -- New York, N.Y. -- Science. 1984 Nov 16;226(4676):843-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6494915" target="_blank"〉PubMed〈/a〉

    Beschreibung: The article "Reagan seeks expansion of Soviet ties" by R. Jeffrey Smith (News and Comment, 13 July, p. 145) erroneously stated that the U.S. Senate had passed a resolution calling for a U.S.-Soviet summit "without preconditions or assurances of success." Shortly before midnight on 19 June, the resolution was amended to call for a summit at "the earliest practical time following thorough preparation." It was approved in this form.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jako, G J -- New York, N.Y. -- Science. 1984 Aug 3;225(4661):462.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6740318" target="_blank"〉PubMed〈/a〉

    Beschreibung: There is increasing recognition that federal food safety laws and policies need to be revised. Congressional debate on proposed amendments to the Food, Drug, and Cosmetic Act has generated several different perspectives on how the food safety laws should be changed. Before a consensus can be reached, scientists, regulators, the food industry, and consumers will have to review such complex and controversial issues as the level of acceptable risk, the value of risk-benefit analysis, the proper role of independent scientific review, and the reliability of quantitative risk assessment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kessler, D A -- New York, N.Y. -- Science. 1984 Mar 9;223(4640):1034-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6695192" target="_blank"〉PubMed〈/a〉
