    Phosphorus distribution in the nucleosome (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-01-09
    Description: The spatial distribution of phosphorus within active fraction nucleosomes reveals that the path of the DNA is consistent with one and three-fourths turns of DNA supercoiled around the outside of the protein core. This phosphorus distribution, obtained with an imaging electron spectrometer in a conventional transmission electron microscope, simultaneously establishes new limits of sensitivity for elemental microanalysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bazett-Jones, D P -- Ottensmeyer, F P -- New York, N.Y. -- Science. 1981 Jan 9;211(4478):169-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444457" target="_blank"〉PubMed〈/a〉

    Milk of dairy cows frequently contains a leukemogenic virus (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-28
    Description: Milk or viable milk cells collected from 24 dairy cattle naturally infected with bovine leukemia virus were inoculated into lambs, which were subsequently examined for the development of infection. With this bioassay, infectious virus was demonstrated in the milk of 17 of the cows. Bovine leukemia virus is leukemogenic in at least two mammalian species, is widespread in commercial dairy herds, and can infect a wide range of hosts in vivo and cells, including human cells, in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferrer, J F -- Kenyon, S J -- Gupta, P -- 3PO1-CA-14193/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Aug 28;213(4511):1014-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6267692" target="_blank"〉PubMed〈/a〉

    Cloned viral protein vaccine for foot-and-mouth disease: responses in cattle and swine (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-12-04
    Description: A DNA sequence coding for the immunogenic capsid protein VP3 of foot-and-mouth disease virus A12, prepared from the virion RNA, was ligated to a plasmid designed to express a chimeric protein from the Escherichia coli tryptophan promoter-operator system. When Escherichia coli transformed with this plasmid was grown in tryptophan-depleted media, approximately 17 percent of the total cellular protein was found to be an insoluble and stable chimeric protein. The purified chimeric protein competed equally on a molar basis with VP3 for specific antibodies to foot-and-mouth disease virus. When inoculated into six cattle and two swine, this protein elicited high levels of neutralizing antibody and protection against challenge with foot-and-mouth disease virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleid, D G -- Yansura, D -- Small, B -- Dowbenko, D -- Moore, D M -- Grubman, M J -- McKercher, P D -- Morgan, D O -- Robertson, B H -- Bachrach, H L -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1125-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6272395" target="_blank"〉PubMed〈/a〉

    Bovine babesiosis: protection of cattle with culture-derived soluble Babesia bovis antigen (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-04-17
    Description: Adult Hereford (Bos taurus) cattle were protected from severe reactions and death caused by the tick-borne protozoan hemoparasite Babesia bovis, 3 months after vaccination with a cell culture--derived immunogen. The immunogen consisted of filtered, freeze-dried supernatant fluid collected from long-term cultures of Babesia bovis in vitro. It was reconstituted with saponin adjuvant and injected twice subcutaneously at 2-week intervals. Serum collected from vaccinated cattle caused thickening of the merozoite surface coat, aggregation, and lysis of merozoites in vitro. This reaction was identical to that caused by serum from immune carrier cattle suggesting that the protective antigen present in culture fluids is merozoite surface coat antigen. No mortality occurred among vaccinated cattle, whereas mortality among unvaccinated cattle and Babesia bigemina--immune cattle was 62.5 percent indicating that immunity to bovine babesiosis is species-specific.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, R D -- James, M A -- Ristic, M -- Aikawa, M -- Vega y Murguia, C A -- AI 16680/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):335-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209532" target="_blank"〉PubMed〈/a〉

    Publication Date: 1981-09-25
    Description: Fermentation of food by the microbial community of the rumen is essential for the maintenance and growth of ruminants. The microbial ecosystem and its interaction with the host are described, along with recent attempts to manipulate the composition and activity of the microbial community by adding antibiotics and other chemicals to ruminant diets. A similar microbial community and fermentation occur in the large intestine or cecum of most nonruminant animals including the large intestine of humans. The microbial ecosystems of the rumen and human large intestine are compared.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolin, M J -- New York, N.Y. -- Science. 1981 Sep 25;213(4515):1463-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280665" target="_blank"〉PubMed〈/a〉

    Mechanisms of gonadal differentiation (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-03-20
    Description: Sex differentiation is the result of the translation of genetic sex into gonadal sex. Without recognizable masculinizing signals the embryonic gonad will undergo ovarian differentiation. The main determinant of gonadal differentiation appears to be the presence or absence of a cell surface antigen, called H-Y antigen. The regulation of H-Y antigen expression is complex and involves the interaction between regulatory sites on the Y chromosome, the X chromosome, and possibly the autosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haseltine, F P -- Ohno, S -- 5R01 HD 12289-02/HD/NICHD NIH HHS/ -- R0I AD 00042/AD/ADAMHA HHS/ -- New York, N.Y. -- Science. 1981 Mar 20;211(4488):1272-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010601" target="_blank"〉PubMed〈/a〉

    Morphine in cow and human milk: could dietary morphine constitute a ligand for specific morphine (mu) receptors? (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-28
    Description: Morphine has been found in cow and human milk at concentrations of 200 to 500 nanograms per liter. Multistep purification yields a material that has immunological, biological, pharmacological, and chemical properties identical to those of morphine. Similar morphine-like material, which has been tentatively identified in some common plant sources, may be a ubiquitous dietary constituent and a possible source for the material in milk. Since morphine (mu) receptors have a low affinity for enkephalins, and since morphine-like materials have been described in brain and intestine, it is possible that morphine in food may be the source of this material and a normal ligand specific for mu receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hazum, E -- Sabatka, J J -- Chang, K J -- Brent, D A -- Findlay, J W -- Cuatrecasas, P -- New York, N.Y. -- Science. 1981 Aug 28;213(4511):1010-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6267691" target="_blank"〉PubMed〈/a〉

    Nonenzymatic browning in vivo: possible process for aging of long-lived proteins (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-01-30
    Description: The incubation of lens proteins with reducing sugars leads to the formation of fluorescent yellow pigments and cross-like similar to those reported in aging and cataractous human lenses. Called nonenzymatic browning or the Maillard reaction, this aging process also occurs in stored foods. Reducing sugars condense with the free amino group of proteins, then rearrange and dehydrate to form unsaturated pigments and cross-linked products. Although most proteins in living systems turn over with sufficient rapidity to avoid nonenzymatic browning, some, such as lens crystallins and skin collagen, are exceptionally long-lived and may be vulnerable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Monnier, V M -- Cerami, A -- AM 19655/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):491-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6779377" target="_blank"〉PubMed〈/a〉

    Description: A monoclonal antibody (immunoglobulin G1) has been produced that reacts against myelin basic protein present in or extracted from the brains of many mammals-with certain important exceptions. Because of known species differences in amino acid sequences of basic protein and of certain peptide fragments, the binding site for this particular antibody appeared likely to include residues 130 to 137.

The toxin is a complex polysaccharide composed of glucose, glucosamine or galactosamine, and a heptose, is heat-stable, devoid of protein and lipid, and has a molecular weight of 73,000. The holotoxin in the cell membrane is a glycoprotein; however, it is the polysaccharide portion that is toxic. This inflammatory toxin increases vascular permeability and is capable of activating complement. Infusion of 0.9 milligram of toxin into the bovine udder resulted in the characteristic eosinophilic mastitis produced by Mycoplasma bovine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geary, S J -- Tourtellotte, M E -- Cameron, J A -- New York, N.Y. -- Science. 1981 May 29;212(4498):1032-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233196" target="_blank"〉PubMed〈/a〉

    Fidelity of mammalian DNA polymerases (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-14
    Description: The fidelity of copying natural DNA in vitro with each of the three classes of eukaryotic DNA polymerases has been determined. DNA polymerases-beta and -gamma are highly inaccurate, catalyzing noncomplementary single-base substitution at a frequency between 1/3000 and 1/8000. DNA polymerase-alpha is substantially more accurate, with an error rate of 1/30,000. When the error rates of these DNA polymerases are considered in the context of the accuracy of DNA replicative processes in vivo, it seems likely that other factors must exist in mammalian cells which are involved in the accurate replication and maintenance of the genetic information.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kunkel, T A -- Loeb, L A -- New York, N.Y. -- Science. 1981 Aug 14;213(4509):765-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6454965" target="_blank"〉PubMed〈/a〉

    Inserted sequences in bovine satellite DNA's (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-07-24
    Description: The nucleotide sequence of the 1413-base-pair repeat unit of bovine 1.711a satellite DNA (density in cesium chloride, 1.711 grams per cubic centimeter) has been determined. The repeat unit contains two segments consisting of variants of a basic 23-base-pair sequence that is closely related to sequences of bovine 1.706 satellite DNA. A third segment of the repeat unit contains an unrelated 611-base-pair sequence that is not internally repetitive. This segment is flanked by inverted repeats of 8 base pairs and, on one side, by a direct repeat of the terminal sequence. A related segment is present in bovine 1.711b satellite DNA and is inserted into sequences derived from the 1.715 satellite. These nucleotide sequences suggest the timing of some of the stages in the evolution of these complex, closely related satellite DNA's and indicate the mechanisms inherent in their divergence from a common ancestor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Streeck, R E -- New York, N.Y. -- Science. 1981 Jul 24;213(4506):443-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6264600" target="_blank"〉PubMed〈/a〉

    Cadmium-113 nuclear magnetic resonance studies of bovine insulin: two-zinc insulin hexamer specifically binds calcium (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-01
    Description: By use of cadmium-113 nuclear magnetic resonance spectroscopy, a specific calcium ion binding site has been identified in the bovine two-zinc insulin hexamer. This site is composed of six glutamyl carboxylate groups clustered in the center of the hexamer, and is distinct from the normal zinc ion binding sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sudmeier, J L -- Bell, S J -- Storm, M C -- Dunn, M F -- 5S05RR 07010-09/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 May 1;212(4494):560-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010607" target="_blank"〉PubMed〈/a〉
