    Benzo(a)pyrene-7,8-dihydrodiol 9,10-oxide adenosine and deoxyadenosine adducts: structure and stereochemistry (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: The structure and absolute stereoconfigurations of four adenosine adducts with (+/-)-7 alpha,8 beta-dihydroxy-9 beta, 10 beta-epoxy-7,8,9,10-tetrahydrobenzo(a)pyrene (BPDE) and their deoxyadenosine analogs have been determined. They result from both cis and trans addition of the N6 amino group of ademine to the 10 position of both enantiomers of BDPE. This was determined from studies of the nuclear magnetic resonance spectra, mass spectra, and circular dichroism spectra, as well as from their pKa values and chemical reactivities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jeffrey, A M -- Grzeskowiak, K -- Weinstein, I B -- Nakanishi, K -- Roller, P -- Harvey, R G -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1309-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/316186" target="_blank"〉PubMed〈/a〉

    Genetic mechanism accounting for precise immunoglobulin domain deletion in a variant of MPC 11 myeloma cells (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: A variant of the MPC 11 cell line, M 311, produces a short immunoglobulin heavy chain. When compared with the parental gamma 2b heavy chain, M 311 was found to have a carboxyl terminal deletion comprising the CH3 domain. The COOH-terminal cyanogen bromide (CNBr) cleavage fragment of M 311 is identical to a corresponding segment ofa parental heavy chain CNBr fragment, with the exception of a substitution of asparagine for lysine at the COOH-terminal residue. This observation enabled prediction of both the parental DNA sequence in this region and the genetic mechanism which generated the variant, a frameshift followed by premature termination. This hypothesis is supported by studies of the DNA sequence of the MPC 11 gamma 2b constant region gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kenter, A L -- Birshtein, B K -- R21 AI106328/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1307-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/117550" target="_blank"〉PubMed〈/a〉

    Dynamics of skeletal pattern formation in developing chick limb (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-17
    Description: During development of the embryonic chick limb the skeletal pattern is laid out as cartilaginous primordia, which emerge in a proximodistal sequence over a period of 4 days. The differentiation of cartilage is preceded by changes in cellular contacts at specific locations in the precartilage mesenchyme. Under realistic assumptions, the biosynthesis and diffusion through the extracellular matrix of a cell surface protein, such as fibronectin, will lead to spatial patterns of this molecule that could be the basis of the emergent primordia. As cellular differentiation proceeds, the size of the mesenchymal diffusion chamber is reduced in descrete steps, leading to sequential reorganizations of the morphogen pattern. The successive patterns correspond to observed rows of skeletal elements, whose emergence, in theory and in practice, depends on the maintenance of a unique boundary condition at the limb bud apex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Newman, S A -- Frisch, H L -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):662-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/462174" target="_blank"〉PubMed〈/a〉

    Osmotic shock prevents nuclear exchange and produces whole-genome homozygotes in conjugating Tetrahymena (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-02-16
    Description: Exposure of conjugating Tetrahymena to a hyperosmotic shock blocks the exchange of gametic nuclei and produces self-fertilized exconjugants that are homozygous for their whole genome. Cells are sensitive to this induction during a brief period after meiosis. The high efficiency of the treatment and the fertility of the progeny make this a useful method for the isolation of induced recessive mutations and enhances the value of Tetrahymena as an animal-cell model system in which genetic dissection is practical. The sharp peak of sensitivity is useful in the study of those cellular mechanisms responsible for the independent handling of several functionally distinct nuclei during conjugation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Orias, E -- Hamilton, E P -- Flacks, M -- New York, N.Y. -- Science. 1979 Feb 16;203(4381):660-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/760210" target="_blank"〉PubMed〈/a〉

    Albumin-deficient rat mutant (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-10
    Description: An analbuminemic colony was established from Sprague-Dawley rats. Analbuminemia was inherited as an autosomal recessive trait. The rates of growth and reproduction of the mutant rats were no different from those of normal rats. Biochemically, the mutant was characterized by an extraordinarily low serum albumin content and a hyperlipidemia. Total serum protein in the mutant rat was similar to that of control Sprague-Dawley rats, with increased globulin. Serum cholesterol was inversely correlated with a decrease in albumin; the correlation coefficient for ablumin was --.92. These mutant rats may serve as a model of human familial analbuminemia and may also be useful in elucidating the functional roles of albumin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nagase, S -- Shimamune, K -- Shumiya, S -- New York, N.Y. -- Science. 1979 Aug 10;205(4406):590-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451621" target="_blank"〉PubMed〈/a〉

    Description: A hydrostatic pressure of only 68 atmospheres prevented swimming Paramecium caudatum from "avoiding" or reversing direction; 170 atmospheres stopped or decreased forward velocity by more than 75 percent. A decompression of 40 atmospheres invoked a single reversal, even at ,80 atmospheres. In contrast, 170 atmospheres did not significantly affect swimming behavior of paramecium "models" that were reactivated in a solution containing adenosine triphosphate and magnesium ions after their membrane had been disrupted by Triton X-100.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Otter, T -- Salmon, E D -- New York, N.Y. -- Science. 1979 Oct 19;206(4416):358-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/482945" target="_blank"〉PubMed〈/a〉

    Malignant neoplasms of genetic origin in Drosophila melanogaster (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-06-30
    Description: Malignant neoplasms that develop in 12 recessive-lethal, larval mutants of Drosophila melanogaster are discussed. These mutations affect the adult optic neuroblasts and ganglion-mother cells in the larval brain, the imaginal discs, and the hematopoietic organs. The malignant neoplasms exhibit fast, autonomous growth, loss of the capacity for differentiation, increased mobility and invasiveness, lethality in situ and after transplantation, and histological, fine structural, and karyotypic abnormalities. Intermediate neoplasms are also found. These combine both benign and malignant qualities. They grow in a noninvasive, compact fashion, typical of benign tumors, yet they also exhibit malignant qualities such as fast, autonomous, and lethal growth, loss of differentiation capacity, changes in cellular morphology, and lethal growth after transplantation into wild-type hosts. Thus Drosophila and vertebrate neoplasms show striking similarities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gateff, E -- New York, N.Y. -- Science. 1978 Jun 30;200(4349):1448-59.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/96525" target="_blank"〉PubMed〈/a〉

    alpha1-Antitrypsin: the presence of excess mannose in the Z variant isolated from liver (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-09-29
    Description: The Z variant of alpha1-antitrypsin was isolated by a new technique from the liver of a patient homozygous for the Z allele of the protease inhibitor locus. The material was homogenous and antigenically competent but had no protease inhibiting capacity. An interesting correlation was found between the subcellular localization and the carbohydrate composition of the Z variant from liver. Carbohydate analysis of this glycoprotein showed an absence of galactose and sialic acid, an appreciable decrease in N-acetylglucosamine, and an almost twofold increase in mannose residues. These data indicate a considerable slowdown in the processing of the oligosaccharides of liver Z variant. In spite of the absence of sialyl residues, the liver Z varant was microheterogeneous by analytical isoelectric focusing. The isoproteins of liver Z variant coincided with those of asialo M variant in the focusing field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hercz, A -- Katona, E -- Cutz, E -- Wilson, J R -- Barton, M -- New York, N.Y. -- Science. 1978 Sep 29;201(4362):1229-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/308696" target="_blank"〉PubMed〈/a〉

    Description: Cytoplasmic extracts of proliferating cells stimulate DNA synthesis in isolated nuclei of Xenopus laevis liver. When tested by the same assay, cytoplasmic extracts of resting cells are completely inactive. When cytoplasmic extracts are prepared from cell cycle-specific temperature-sensitive mutants arrestd in the G1 phase of the cell cycle by the nonpermissive temperature, they also fail to stimulate DNA synthesis in frog nuclei. The results indicate that, to stimulate DNA synthesis in isolated frog nuclei, essentially all information of G1 cells must be present.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Floros, J -- Chang, H -- Baserga, R -- New York, N.Y. -- Science. 1978 Aug 18;201(4356):651-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/675253" target="_blank"〉PubMed〈/a〉

    Description: After condinous cultivation in the presence of chloroquine, an African strain of the malaria parasite, Plasmodium falciparu, acquired resistance to the drug. The resistance was stable and comparable in vitro to that occurring naturally in a strain from Southeast Asia. This suggests that chloroquine resistance, absent until now in Africa, might arise in the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nguyen-Dinh, P -- Trager, W -- New York, N.Y. -- Science. 1978 Jun 23;200(4348):1397-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/351801" target="_blank"〉PubMed〈/a〉

    Control of sequential compartment formation in Drosophila (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-01-20
    Description: During development of Drosophila melanogaster, sequential commitment to alternative development programs occurs in neighboring groups of cells. These commitments appear to be reflected by lines of clonal restriction, called compartmental boundaries, which progressively subdivide the early embryo, and later the imaginal discs, which give rise to different adult appendages. We propose that a reaction-diffusion system acts throughout development and generates a sequence of differently shaped chemical patterns. These patterns account for the sequence and geometries of compartmental boundaries, and predict that each terminal compartment is specifiied by a unique combination of binary choices made during its formation. This binary "code" interprets coherently the patterned metaplasia seen in transdetermination and homeotic mutations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kauffman, S A -- Shymko, R M -- Trabert, K -- New York, N.Y. -- Science. 1978 Jan 20;199(4326):259-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/413193" target="_blank"〉PubMed〈/a〉

    A mutant of yeast defective in cellular morphogenesis (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-06-09
    Description: In the budding yeast Saccharomyces cerevisiae, each bud appears within a ring of chitin formed in the cell wall of the mother cell. Temperature-sensitive mutants defective in gene cdc24 synthesize chitin at restrictive temperatures, but do not organize it into the discrete rings found in normal cells, nor do they form buds. The chitin ring or an annular precursor structure may play an essential role in reinforcing the region of the cell wall involved in budding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sloat, B F -- Pringle, J R -- New York, N.Y. -- Science. 1978 Jun 9;200(4346):1171-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/349694" target="_blank"〉PubMed〈/a〉

    Genetic method for the preferential elimination of females of anopheles albimanus (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-06-16
    Description: Recent field experiments demonstrated the possibility of using the sterile male method for the control of Anopheles albimanus Wiedemann, the most important vector of human malaria in Central America. Until now there was no practical method for excluding females from the releases of sterile males. A genetic method was developed for the preferential elimination of females during any of the four life stages. This genetic sexing system utilizes propoxur (o-isopropoxyphenyl methyl-carbamate) susceptibility as a recessive conditional lethal a T(Y:2R) translocation, and an In(2R)inversion. The propoxur resistance allele (dominant) was linked to the Y chromosome via a radiation-induced translocation, and genetic recombination was suppressed by inversions. In one of the strains produced, 99.7 percent of the females are eliminated when treated with propoxur, without male loss.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seawright, J A -- Kaiser, P E -- Dame, D A -- Lofgren, C S -- New York, N.Y. -- Science. 1978 Jun 16;200(4347):1303-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663614" target="_blank"〉PubMed〈/a〉
