    Reorganization of the axon membrane in demyelinated peripheral nerve fibers: morphological evidence (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-07
    Description: Cytochemical staining of demyelinated peripheral axons revealed two types of axon membrane organization, one of which suggests that the demyelinated axolemma acquires a high density of sodium channels. Ferric ion-ferrocyanide stain was confined to a restricted region of axon membrane at the beginning of a demyelinated segment or was distributed throughout the demyelinated segment of axon. The latter pattern represents one possible morphological correlate of continuous conduction through a demyelinated segment and suggests a reorganization of the axolemma after demyelination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Foster, R E -- Whalen, C C -- Waxman, S G -- NS-15320/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 7;210(4470):661-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6159685" target="_blank"〉PubMed〈/a〉

    Survival of mice receiving melanoma transplants is promoted by hydroquinone (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-25
    Description: In BALB/c female mice with melanoma transplants, the incidence of "takes" is decreased and survival is increased by hydroquinone, a melanocytolytic agent. The mechanism of drug action is suggested by via DNA. The significant and high degree of positive response to hydroquinone treatment in vivo is encouraging for the clinical management of melanoma with melanocytolytic agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chavin, W -- Jelonek, E J Jr -- Reed, A H -- Binder, L R -- New York, N.Y. -- Science. 1980 Apr 25;208(4442):408-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7367868" target="_blank"〉PubMed〈/a〉

    Role of the spleen in the growth of a murine B cell leukemia (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-04
    Description: A spontaneous B cell leukemia (BCL1) grew progressively in normal BALB/c mice after injection of tumor cells but did not grow in splenectomized recipients. Despite the absence of progressive tumor growth, residual tumor cells with malignant potential were found in the peripheral blood of the splenectomized animals. Splenectomy performed after injection of tumor cells but before the development of marked leukocytosis also prevented progressive tumor growth and death of the host. Thus the spleen appears to be necessary for progressive proliferation of this lymphocytic leukemia early after passage in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kotzin, B L -- Strober, S -- New York, N.Y. -- Science. 1980 Apr 4;208(4439):59-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6965803" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-03-14
    Description: Mebendazole was highly effective against the helminth parasite Trichinella spiralis in mice subjected to a 3-day course of treatment during the invasive and encystment phases of experimental trichinellosis. When treatment began either 2 or 4 weeks after the mice were inoculated with parasites, the number of larvae developing in the host musculature was greatly reduced by twice-daily oral administration of 3.125, 6.25, or 12.5 milligrams of mebendazole per kilogram of body weight.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCracken, R O -- Taylor, D D -- New York, N.Y. -- Science. 1980 Mar 14;207(4436):1220-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355285" target="_blank"〉PubMed〈/a〉

    Animal anorexias (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-22
    Description: Eating very little in the presence of food or failure to serach for food has been documented in various species during the hibernation season, incubation, molting, and defense of the territory or harem. At these times feeding competes with other, more important activities. One way to avoid conflicts between feeding and these other activities to lower the programmed weight or set-point for body fat. Experiments on mammalian hibernators and incubating birds provide evidence that set-points are indeed lowered. Failure to eat in these two examples depends on anorexia, loss of appetite. A review of other examples suggests that conceptualization in terms of lowered set-points provides a unified and testable way of understanding many naturally occurring instances of fasting in the animal kingdom. Finally, spontaneous animal anorexias are contrasted with attempts by people to lose weight.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mrosovsky, N -- Sherry, D F -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):837-42.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6928327" target="_blank"〉PubMed〈/a〉

    Genes for growth hormone, chorionic somatommammotropin, and growth hormones-like gene on chromosome 17 in humans (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-11
    Description: The human genes for growth hormone (GH), chorionic somatomammotropin (CSH), and a third growth hormone-like gene (GHL) have been located on chromosome 17 in humans. DNA fragments of 2.6, 2.8, and 9.5 kilobase pairs containing GH, CSH, and GHL, respectively, were identified in human genomic DNA, and a 7.5-kilobase DNA fragment related to growth hormone DNA sequences was found in mouse cells. In somatic hybrids of human and mouse cells containing reduced numbers of human chromosomes, but a normal complement of mouse chromosomes, the mouse, 7.5-kolobase DNA fragment was always present, whereas the 2.6-, 2.8-, and 9.5-kilobase human fragments were present only when human chromosome 17 was also present.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owerbach, D -- Rutter, W J -- Martial, J A -- Baxter, J D -- Shows, T B -- New York, N.Y. -- Science. 1980 Jul 11;209(4453):289-92.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384802" target="_blank"〉PubMed〈/a〉

    Estrogen and the growth of breast cancer: new evidence suggests indirect action (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-08
    Description: The growth of the MCF-7 human breast cancer cell line is unresponsive to the presence of estrogen in culture media. Paradoxically, in nude mice, growth of these cells and formation of solid tumors are dependent on estrogen. Tumors fail to develop in ovariectomized mice, but do develop in intact mice and in ovariectomized mice given estrogen. Primary cultures derived from MCF-7 tumors revert to unresponsiveness to estrogen. However, when these cultures are again transplanted into nude mice, estrogen is required for tumor formation. The continuous culture, the solid tumor, and the primary cultures therefrom have similar estrogen-binding capacities and affinities. These results indicate that mammary carcinoma cell growth in vivo is subject to inhibition that can be overcome by estrogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shafie, S M -- New York, N.Y. -- Science. 1980 Aug 8;209(4457):701-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6994231" target="_blank"〉PubMed〈/a〉

    Latency of herpes simplex virus in absence of neutralizing antibody: model for reactivation (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-28
    Description: Mice inoculated with herpes simplex virus (type 1) by the lip or corneal route and then passively immunized with rabbit antibody to herpes simplex virus developed a latent infection in the trigeminal ganglia within 96 hours. Neutralizing antibody to herpes simplex virus was cleared from the circulation and could not be detected in most of these mice after 2 months. Examination of ganglia from the antibody-negative mice revealed latent virus in over 90 percent of the animals, indicating that serum neutralizing antibody is not necessary to maintain the latent state. When the lips or corneas of these mice were traumatized, viral reactivation occurred in up to 90 percent of the mice, as demonstrated by the appearance of neutralizing antibody. This study provides a model for identifying factors that trigger viral reactivation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sekizawa, T -- Openshaw, H -- Wohlenberg, C -- Notkins, A L -- New York, N.Y. -- Science. 1980 Nov 28;210(4473):1026-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6254149" target="_blank"〉PubMed〈/a〉

    Phase transition and crystal structure of the 37 degrees C form of cholesterol (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-06
    Description: Crystalline cholesterol undergoes a phase transition a few degrees below human body temperature. The high-temperature form has an unusually complex structure with 16 independent molecules. In the transition two molecules change side chain conformation, four reorient about their long axes, and ten remain unchanged. The transition mechanism implies relatively nonspecific intermolecular interactions, qualitatively consistent with the behavior of cholesterol in biomembranes. The transition preserves a remarkably closely obeyed pseudosymmetry present in the structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hsu, L Y -- Nordman, C E -- GM15259/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 May 6;220(4597):604-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836303" target="_blank"〉PubMed〈/a〉

    Synthesis of kappa light chains by cell lines containing an 8;22 chromosomal translocation derived from a male homosexual with Burkitt's lymphoma (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-12-09
    Description: Three cell lines were derived from a homosexual patient with probable acquired immunodeficiency syndrome and Burkitt's lymphoma. The cell lines produce an unusual strain of Epstein-Barr virus which will both transform cord blood lymphocytes and induce early antigens in Raji cells. Translocations between chromosomes 8 and 22 have occurred in all three lines, but the cells synthesize immunoglobulin M with light chains of the kappa type, in contrast to the usual concordance between a translocation involving chromosome 22 and lambda chain synthesis. Both kappa genes and one lambda gene are rearranged. These findings indicate either that translocation may occur as a separate event from immunoglobulin gene rearrangement or that the proposed hierarchical sequence of immunoglobulin gene rearrangements is not always adhered to. The data also imply that in cells containing a translocation between the long arm of chromosome 8 and a chromosome bearing an immunoglobulin gene, alteration of cellular myc expression may occur regardless of the immunoglobulin gene that is expressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Magrath, I -- Erikson, J -- Whang-Peng, J -- Sieverts, H -- Armstrong, G -- Benjamin, D -- Triche, T -- Alabaster, O -- Croce, C M -- New York, N.Y. -- Science. 1983 Dec 9;222(4628):1094-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316501" target="_blank"〉PubMed〈/a〉

    Description: Highly purified preparations of insulin receptor catalyzed the phosphorylation of the 95,000-dalton subunit of the insulin receptor. This subunit of the insulin receptor was also labeled with [alpha-32P]8-azidoadenosine 5'-triphosphate, a photoaffinity label for adenosine triphosphate binding sites. The identity of the 95,000-dalton band was confirmed in both cases by precipitation with a monoclonal antibody to the insulin receptor. These results suggest that the insulin receptor is itself a protein kinase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roth, R A -- Cassell, D J -- New York, N.Y. -- Science. 1983 Jan 21;219(4582):299-301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6849137" target="_blank"〉PubMed〈/a〉

    Leukotrienes: mediators of immediate hypersensitivity reactions and inflammation (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-06
    Description: Arachidonic acid plays a central role in a biological control system where such oxygenated derivatives as prostaglandins, thromboxanes, and leukotrienes are mediators. The leukotrienes are formed by transformation of arachidonic acid into an unstable epoxide intermediate, leukotriene A4, which can be converted enzymatically by hydration to leukotriene B4, and by addition of glutathione to leukotriene C4. This last compound is metabolized to leukotrienes D4 and E4 by successive elimination of a gamma-glutamyl residue and glycine. Slow-reacting substance of anaphylaxis consists of leukotrienes C4, D4, and E4. The cysteinyl-containing leukotrienes are potent bronchoconstrictors, increase vascular permeability in postcapillary venules, and stimulate mucus secretion. Leukotriene B4 causes adhesion and chemotactic movement of leukocytes and stimulates aggregation, enzyme release, and generation of superoxide in neutrophils. Leukotrienes C4, D4, and E4, which are released from the lung tissue of asthmatic subjects exposed to specific allergens, seem to play a pathophysiological role in immediate hypersensitivity reactions. These leukotrienes, as well as leukotriene B4, have pro-inflammatory effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Samuelsson, B -- New York, N.Y. -- Science. 1983 May 6;220(4597):568-75.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6301011" target="_blank"〉PubMed〈/a〉

    Herpes simplex virus glycoprotein D: human monoclonal antibody produced by bone marrow cell line (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-07-08
    Description: Normal bone marrow cells from a donor positive for herpes simplex virus were transformed with Epstein-Barr virus. The resulting lymphoblastoid cell line has secreted immunoglobulin G1 of the kappa type continuously for 2 years. This immunoglobulin, detected both on the cell surface and in the cytoplasm, reacts with cells infected with herpes simplex virus. It defines an antigen that comigrates with the 55-kilodalton glycoprotein D of herpes simplex virus type 1 and neutralizes the infectivity of herpes simplex viruses 1 and 2.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seigneurin, J M -- Desgranges, C -- Seigneurin, D -- Paire, J -- Renversez, J C -- Jacquemont, B -- Micouin, C -- New York, N.Y. -- Science. 1983 Jul 8;221(4606):173-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6304881" target="_blank"〉PubMed〈/a〉

    Bovine x mouse hybridomas that secrete bovine immunoglobulin G1 (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-29
    Description: The interspecific fusion of normal bovine lymphocytes with a nonsecreting mouse hybridoma produced stable cell lines secreting bovine immunoglobulins. One of these lines has continued to secrete immunoglobulin G1 (5 to 10 micrograms per milliliter) for over 16 months. The bovine x mouse hybrid cells can be expected to provide bovine monoclonal immunoglobulins for sequencing studies and for use as serological standards as well as to provide messenger RNA for cloning bovine immunoglobulin genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srikumaran, S -- Guidry, A J -- Goldsby, R A -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):522-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6403985" target="_blank"〉PubMed〈/a〉

    Serological visualization of interleukin 2 (1983)

    Details
    Publication Date: 1983-06-10
    Description: Interleukin 2, a lymphokine that acts as a second signal of cellular immune response by way of its action as a T-cell growth factor, was morphologically identified by immunoperoxidase staining. With the use of a monoclonal antibody to interleukin 2 and several complex-forming antisera, the lymphokine was readily distinguished in cytocentrifuge preparations of peripheral blood leukocytes stimulated with a T-cell mitogen. When preparations of cloned interleukin 2 producer and responder cells were stained by the same procedures, discrete patterns of both responder and producer cell phenotypes were revealed. Interleukin 2 producer T cells exhibited a characteristic intense, ringlike cytoplasmic staining, whereas the responder cells (as exemplified by interleukin 2-dependent cell lines) exhibited a less intensive, spotlike membrane staining. In addition, intense membrane localization of interleukin 2, reminiscent of potential capping phenomena, could be observed in stained preparations of cloned responder cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steinmann, G -- Conlon, P -- Hefeneider, S -- Gillis, S -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1188-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6344215" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1983-09-16
    Description: A twofold thickening of capillary basement membranes of rat retinas resulting from dietary galactose was prevented by sorbinil, an inhibitor of aldose reductase. Since the basement membrane thickening was ultrastructurally similar to that typical of diabetic retinopathy, it may indicate changes in vessel permeability and susceptibility to hemorrhage. Galactosemic rats should be useful models for studying basement membrane-related complications of diabetes and for examining the potential biochemical regulation of basement membrane synthesis by aldose reductase inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robison, W G Jr -- Kador, P F -- Kinoshita, J H -- New York, N.Y. -- Science. 1983 Sep 16;221(4616):1177-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6612330" target="_blank"〉PubMed〈/a〉

    Bromine residue at hydrophilic region influences biological activity of aplysiatoxin, a tumor promoter (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-12-16
    Description: Aplysiatoxin and debromoaplysiatoxin, which are isolated from the seaweed, Lyngbya gracilis, differ in their chemical structure only by the presence or absence of a bromine residue in the hydrophilic region. The function and the structure-activity relation of the hydrophilic region are not known. Aplysiatoxin increased malignant transformation, stimulated DNA synthesis, and inhibited the binding of phorbol-12,13-dibutyrate and epidermal growth factor to cell receptors. Debromoaplysiatoxin inhibited the binding of these two substances as strongly as aplysiatoxin but did not increase malignant transformation or stimulate DNA synthesis. These results indicate that a slight change in the chemical structure of the hydrophilic region of aplysiatoxin affects its abilities to increase cell transformation and stimulate DNA synthesis and that the abilities of the tumor promoters to inhibit the binding of phorbol-12,13-dibutyrate and epidermal growth factor are dissociable from their abilities to increase cell transformation and stimulate DNA synthesis under some circumstances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shimomura, K -- Mullinix, M G -- Kakunaga, T -- Fujiki, H -- Sugimura, T -- New York, N.Y. -- Science. 1983 Dec 16;222(4629):1242-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316505" target="_blank"〉PubMed〈/a〉

    DNA-binding proteins (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-09-09
    Description: The structures of three proteins that regulate gene expression have been determined recently and suggest how these proteins may bind to their specific recognition sites on the DNA. One protein (Cro) is a repressor of gene expression, the second (CAP) usually stimulates gene expression, and the third (lambda repressor) can act as either a repressor or an activator. The three proteins contain a substructure consisting of two consecutive alpha helices that is virtually identical in each case. Structural and amino acid sequence comparisons suggest that this bihelical fold occurs in a number of proteins that regulate gene expression, and is an intrinsic part of the DNA-protein recognition event. The modes of repression and activation by Cro and lambda repressor are understood reasonably well, but the mode of action of CAP is still unclear.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeda, Y -- Ohlendorf, D H -- Anderson, W F -- Matthews, B W -- GM20066/GM/NIGMS NIH HHS/ -- GM28138/GM/NIGMS NIH HHS/ -- GM30894/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 9;221(4615):1020-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308768" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-02-08
    Description: Regulation of hemoglobin synthesis depends in part on the population of cells available for erythroid differentiation. Mouse erythroleukemia cells were cloned, and the clones were induced with dimethyl sulfoxide to test the relative induction of beta minor and beta major synthesis. Cells of line 745 produced approximately 35 percent beta minor after induction, and 39 clones of line 745 produced from 23 to 61 percent beta minor. Further subcloning of the clone that produced 61 percent beta minor led to three subclones, all of which produced more than 90 percent beta minor. Thus one kind of hemoglobin regulation occurs at the cellular level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alter, B P -- Goff, S C -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):647-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6928071" target="_blank"〉PubMed〈/a〉

Evidence is presented that this reflects the lipophilic character of the derivative and the very high ratio of lipid to DNA in mitochondria.

    Sparing of the brain in neonatal undernutrition: amino acid transport and incorporation into brain and muscle (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-22
    Description: Rates of tyrosine and lysine transport and incorporation into protein were measured in control and undernourished weanling rats. Undernutrition was induced by feeding lactating dams a low protein diet (12 percent casein) from birth to day 21. At weaning, body and brain weights of undernourished rats were 50 percent and 88 percent, respectively, of control values. Lysine and tyrosine transport rates into skeletal muscle were reduced by over 75 percent, more than twice the reduction seen in brain. Rates of amino acid incorporation into muscle protein were reduced by approximately 50 percent; the change in rate of incorporation into brain protein was not statistically significant. These data indicate that, in spite of marked retardation of amino acid transport into brain, the brain seems fully capable of maintaining normal rates of protein synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freedman, L S -- Samuels, S -- Fish, I -- Schwartz, S A -- Lange, B -- Katz, M -- Morgano, L -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):902-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6766565" target="_blank"〉PubMed〈/a〉

    Description: In concentrates of water produced in a laboratory simulation of a drinking water treatment process, direct-acting, nonvolatile mutagens were readily detected by means of the Ames Salmonella test. The mutagens were shown to be produced by the chlorination process. Treatment of the water with chloramine resulted in less mutagenic activity than treatment with free chlorine. Dechlorination of drinking water with sulfite sharply reduced the mutagenic activity. Treatment with sulfur dioxide is proposed as an effective, inexpensive method of reducing the direct-acting mutagenic activity of drinking water and of aqueous industrial effluents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheh, A M -- Skochdopole, J -- Koski, P -- Cole, L -- New York, N.Y. -- Science. 1980 Jan 4;207(4426):90-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6985746" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-07-18
    Description: The teratogenicity of alcohol has been demonstrated in humans through clinical studies, behavioral studies, and epidemiologic studies, and in animals through controlled laboratory experiments. In humans exposed to alcohol during gestation the effects can range from fetal alcohol syndrome in some offspring of chronic alcoholic women to reduced average birth weight in offspring of women reporting an average consumption of two to three drinks or more per day. The behavioral effects of such exposure may range from mental retardation in children with fetal alcohol syndrome to milder developmental and behavioral effects in infants born to social drinkers. In animals, exposure to alcohol in utero may result in death, malformation, and growth deficiency as well as behavioral and developmental abnormalities. The mechanisms of impairment and related risk factors are yet to be elucidated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Streissguth, A P -- Landesman-Dwyer, S -- Martin, J C -- Smith, D W -- New York, N.Y. -- Science. 1980 Jul 18;209(4454):353-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6992275" target="_blank"〉PubMed〈/a〉

    Anticonvulsants specific for petit mal antagonize epileptogenic effect of leucine enkephalin (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-28
    Description: The anticonvulsants ethosuximide, sodium valproate, and trimethadione that are specific for petit mal epilepsy abolished in rats the electrical seizure activity and behavioral abnormalities produced by leucine enkephalin, whereas phenobarbital and phenytoin had no effect. The dose-response curve for naloxone against seizure activity induced by leucine enkephalin was the same as that in gamma-hydroxybutyrate-induced petit mal. These data indicate that the epileptic properties of leucine enkephalin are petit mal-like and raise the possibility of involvement of enkephalinergic systems in. The dose-response curve for naloxone against seizure activity induced by leucine enkephalin was the same as that in gamma-hydroxybutyrate-induced petit mal.

    Selective reduction of forskolin-stimulated cyclic AMP accumulation by inhibitors of protein synthesis (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-06-10
    Description: Inhibiting protein synthesis by incubating C6-2B rat astrocytoma cells with cycloheximide or emetine for periods up to 24 hours caused a progressive decrease in the accumulation of adenosine 3',5'-monophosphate (cyclic AMP) when the cells were challenged for 30 minutes with 100 microM forskolin. In contrast, cholera toxin-stimulated (6 nM, 3 hours) cyclic AMP accumulation was not diminished in cycloheximide-treated cells, and cyclic AMP was only minimally diminished in response to a 30-minute challenge with 10 microM (-)-isoproterenol. These experiments suggest the presence of a previously unrecognized cyclase component, which is essential for forskolin-stimulated cyclic AMP accumulation and has a shorter half-life than the beta-adrenergic receptor, the guanine nucleotide regulatory proteins, or the cyclase catalytic component.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brooker, G -- Pedone, C -- Barovsky, K -- HL 06330/HL/NHLBI NIH HHS/ -- HL 28940/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1169-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6190226" target="_blank"〉PubMed〈/a〉

    Ethanol modulation of opiate receptors in cultured neural cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-12-16
    Description: The mouse neuroblastoma-rat glioma hybrid cell line NG108-15 was used to study the acute and chronic interaction of ethanol with intact neural cells. In the short term, ethanol inhibited opiate receptor binding, but after long-term exposure the cells exhibited an apparent adaptive increase in the number of opiate binding sites; this was reversible when ethanol was withdrawn. High concentrations of ethanol (200 mM) increased opiate binding after 18 to 24 hours, whereas lower concentrations (25 to 50 mM) produced similar changes after 2 weeks. This model system has potential for exploring the cellular and molecular mechanisms underlying ethanol intoxication, tolerance, and withdrawal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Charness, M E -- Gordon, A S -- Diamond, I -- New York, N.Y. -- Science. 1983 Dec 16;222(4629):1246-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316506" target="_blank"〉PubMed〈/a〉

Evidence is presented showing that stress potentiates cocaine stereotypy as well. These effects of stress were found to be particular to stress that could not be controlled in that rats receiving an identical amount of stress from footshock, but allowed to control its duration, displayed no more stereotypy than did nonstressed rats. These findings have implications for the role of stress and coping in amphetamine and cocaine psychoses, endogenous psychoses, and some forms of schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacLennan, A J -- Maier, S F -- New York, N.Y. -- Science. 1983 Mar 4;219(4588):1091-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6681679" target="_blank"〉PubMed〈/a〉

    Publication Date: 1983-08-19
    Description: Lysates of the protozoan parasite Entamoeba histolytica altered active electrolyte transport when present on the serosal surface of rabbit ileum and rat colon. The lysate-induced effects on electrolyte transport were similar to those caused by serotonin, and were blocked by bufotenine, an analog known to inhibit the action of serotonin. The transport effects were partially inhibited by antibody to serotonin. The amebic lysates were shown to contain serotonin by radioimmunoassay, high-performance liquid chromatography, and thin-layer chromatography. These results suggest that the serotonin present in Entamoeba histolytica may be important in the diarrhea seen in amebiasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGowan, K -- Kane, A -- Asarkof, N -- Wicks, J -- Guerina, V -- Kellum, J -- Baron, S -- Gintzler, A R -- Donowitz, M -- AM26523/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1983 Aug 19;221(4612):762-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308760" target="_blank"〉PubMed〈/a〉

    Heparan sulfate degradation: relation to tumor invasive and metastatic properties of mouse B16 melanoma sublines (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-06
    Description: After transport in the blood and implantation in the microcirculation, metastatic tumor cells must invade the vascular endothelium and underlying basal lamina. Mouse B16 melanoma sublines were used to determine the relation between metastatic properties and the ability of the sublines to degrade enzymatically the sulfated glycosaminoglycans present in the extracellular matrix of cultured vascular endothelial cells. Highly invasive and metastatic B16 sublines degraded matrix glycosaminoglycans faster than did sublines of lower metastatic potential. The main products of this matrix degradation were heparan sulfate fragments. Intact B16 cells (or their cell-free homogenates) with a high potential for lung colonization degraded purified heparan sulfate from bovine lung at higher rates than did B16 cells with a poor potential for lung colonization. Analysis of the degradation fragments indicated that B16 cells have a heparan sulfate endoglycosidase. Thus the abilities of B16 melanoma cells to extravasate and successfully colonize the lung may be related to their capacities to degrade heparan sulfate in the walls of pulmonary blood vessels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakajima, M -- Irimura, T -- Di Ferrante, D -- Di Ferrante, N -- Nicolson, G L -- R01-AM-26482/AM/NIADDK NIH HHS/ -- R01-CA-28867/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 6;220(4597):611-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6220468" target="_blank"〉PubMed〈/a〉

    Description: The uninephrectomized rat given desoxycorticosterone (DOC) provides a classic model of "sodium-dependent" hypertension. In such rats, the extent to which a given dietary intake of sodium induced an increase in blood pressure depended on whether or not the anionic component of the sodium salt was chloride. With normal and high dietary intakes of sodium, sodium chloride induced increases in blood pressure much greater than that induced by approximately equimolar amounts of sodium bicarbonate, sodium ascorbate, or a combination of sodium bicarbonate and sodium ascorbate. A normal amount of dietary sodium chloride induced hypertension, whereas an equimolar amount of sodium bicarbonate did not increase blood pressure. This difference could not be attributed to differences in sodium or potassium balances, weight gain, or caloric intake. The DOC model of "sodium-dependent" hypertension might better be considered sodium chloride-dependent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurtz, T W -- Morris, R C Jr -- R01-AM32631-01/AM/NIADDK NIH HHS/ -- RR-00079/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1983 Dec 9;222(4628):1139-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6648527" target="_blank"〉PubMed〈/a〉

    A glycolipid antigen associated with Burkitt lymphoma defined by a monoclonal antibody (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-29
    Description: The antigen defined by a rat monoclonal antibody directed to a Burkitt lymphoma cell line was identified as globotriaosylceramide [Gal alpha (1 leads to 4)-Gal beta (1 leads to 4)-Glc beta (1 leads to 1)-ceramide]. The antibody demonstrated a strict steric specificity since it did not react with globoisotriaosylceramide [Gal alpha (1 leads to 3)-Gal beta (1 leads to 4)-Glc beta (1 leads to 1)-ceramide], the positional isomer of the antigen associated with the Burkitt lymphoma. Chemical analysis of various Burkitt lymphoma cell lines revealed that the Burkitt lymphoma cells contained more than 100 times as much of the glycolipid antigen as was found in other human lymphoma and leukemia cell lines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nudelman, E -- Kannagi, R -- Hakomori, S -- Parsons, M -- Lipinski, M -- Wiels, J -- Fellous, M -- Tursz, T -- CA 19224/CA/NCI NIH HHS/ -- CA 20026/CA/NCI NIH HHS/ -- GM 23100/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):509-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836295" target="_blank"〉PubMed〈/a〉

    Metastable species of hemoglobin: room temperature transients and cryogenically trapped intermediates (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-06
    Description: Resonance Raman spectra of photolyzed carbonmonoxyhemoglobin obtained with 10-nanosecond pulses are compared with the spectra of photolyzed carbonmonoxyhemoglobin stabilized at 80 K. In comparing the deoxy with the photodissociated species, the changes in the Raman spectra are the same for these two experimental regimes. These results show that at ambient and cryogenic temperatures the heme pocket in liganded hemoglobin is significantly different from that of deoxyhemoglobin. It is concluded that measurements of the properties of intermediate species from photodissociated hemoglobin stabilized at low temperatures can be used to probe the short-lived metastable forms of hemoglobin present after photodissociation under biologically relevant solution conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ondrias, M R -- Friedman, J M -- Rousseau, D L -- New York, N.Y. -- Science. 1983 May 6;220(4597):615-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836305" target="_blank"〉PubMed〈/a〉

    Suppressor T cell action inhibits the expression of an excluded immunoglobulin gene (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-06-24
    Description: Cells of the murine plasmacytoid line MOPC-315 synthesize two distinct immunoglobulin light chains: a normal lambda II protein, which is incorporated into secretory and surface-bound immunoglobulin, and a truncated, nonfunctional lambda I protein found only in the cytoplasm. Idiotype-specific suppressor T lymphocytes selectively inhibit the expression of both lambda II- and lambda I-specific messenger RNA by MOPC-315 cells. This finding demonstrates that phenotypically excluded light chain genes can be subject to immunoregulatory control and suggests that the expression of divergent lambda isotypes may be coordinately regulated in immunoglobulin-secreting cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parslow, T G -- Milburn, G L -- Lynch, R G -- Granner, D K -- AM25295/AM/NIADDK NIH HHS/ -- CA28848/CA/NCI NIH HHS/ -- CA32275/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Jun 24;220(4604):1389-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6222474" target="_blank"〉PubMed〈/a〉

    Publication Date: 1983-09-02
    Description: Fusion of immortal cell lines with normal human fibroblasts or certain other immortal cell lines yields hybrids having limited division potential. Cellular immortality was found to be a recessive phenotype in hybrids. It was also found that at least two separate events in the normal cell genome can result in immortality. In fusions involving certain immortal parent cells, these events can be complemented to result in hybrids with finite division capacity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pereira-Smith, O M -- Smith, J R -- AG 03262/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 2;221(4614):964-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6879195" target="_blank"〉PubMed〈/a〉

    Correlation of glucocorticoid receptor binding sites on MMTV proviral DNA with hormone inducible transcription (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-12-23
    Description: Steroid hormones, when complexed to their receptors, recognize and bind specific DNA sequences and subsequently induce increased levels of transcription. The mechanisms of steroid hormone action were analyzed by constructing chimeric DNA molecules from portions of mouse mammary tumor virus envelope and long terminal repeat (LTR) regions ligated to the thymidine kinase (tk) gene of herpes simplex virus. This construction allowed the tk gene to be expressed in a hormone-responsive fashion upon transfection into Ltk- cells. Comparison of transcription data with in vitro binding data showed that hormone-responsive transcription can be directly correlated to the presence of steroid hormone receptor binding sites on the DNA. There are at least two such receptor binding sites in the LTR region, one between -202 and -137 and another between -137 and -50 base pairs from the RNA cap site, as well as a site near the 5' end of the envelope region. These results strengthen the hypothesis that steroid-receptor complexes regulate genes primarily by binding to DNA sites near the promoter region and thereby modulate transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfahl, M -- McGinnis, D -- Hendricks, M -- Groner, B -- Hynes, N E -- New York, N.Y. -- Science. 1983 Dec 23;222(4630):1341-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6318311" target="_blank"〉PubMed〈/a〉

    Description: Certain human glioma lines produce mucopolysaccharide coats that impair the generation of cytolytic lymphocytes in response to these lines in vitro. Coat production is substantially enhanced by the interaction of glioma cells with a macromolecular factor released by human peripheral blood mononuclear cells in culture. This interaction thus constitutes an unusual mechanism by which inflammatory cells may nonspecifically suppress the cellular immune response to at least one class of solid tumors in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dick, S J -- Macchi, B -- Papazoglou, S -- Oldfield, E H -- Kornblith, P L -- Smith, B H -- Gately, M K -- New York, N.Y. -- Science. 1983 May 13;220(4598):739-42.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6220469" target="_blank"〉PubMed〈/a〉

    Mutation affecting the 12th amino acid of the c-Ha-ras oncogene product occurs infrequently in human cancer (1983)

    Details
    Publication Date: 1983-06-10
    Description: A point mutation alters the 12th amino acid of the c-Ha-ras oncogene product p21 in a human bladder cancer cell line. This is, at present, the only mutation known to result in a human transforming gene. This mutation may therefore represent a possible target for mutagenesis leading to carcinogenesis in humans. By means of restriction enzyme analysis, 29 human cancers, including 20 primary tumor tissues, derived from organs commonly exposed to environmental carcinogens, were tested for the presence of this mutation. None of ten primary bladder carcinomas exhibited the mutation; nor did nine colon carcinomas or ten carcinomas of the lung. Thus the point mutation affecting the 12th amino acid of the c-Ha-ras gene product, while a valuable model for carcinogenesis, does not appear to play a role in the development of most human epithelial cancers of the bladder, colon, or lung.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feinberg, A P -- Vogelstein, B -- Droller, M J -- Baylin, S B -- Nelkin, B D -- 09071/PHS HHS/ -- 24592/PHS HHS/ -- 31053/PHS HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1175-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6304875" target="_blank"〉PubMed〈/a〉

    Normalizing effect of an adrenocorticotropic hormone (4-9) analog ORG 2766 on disturbed social behavior in rats (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-09-02
    Description: Short-term isolation increased the frequency of social interactions in rats tested in pairs, while pairs of rats placed in an unfamiliar test cage and subjected to a high level of illumination spent less time in active social contact. These changes in social behavior elicited by environmental manipulations were counteracted by treatment with the adrenocorticotropic hormone (4-9) analog ORG 2766. The peptide's normalizing effect may be mediated by endogenous opioid systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Niesink, R J -- van Ree, J M -- New York, N.Y. -- Science. 1983 Sep 2;221(4614):960-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308767" target="_blank"〉PubMed〈/a〉

    Rat model for carcinogenesis in ureterosigmoidostomy (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-07
    Description: A rat model is used to study the carcinogenesis that occurs when urine is surgically diverted into the fecal stream, as in ureterosigmoidostomy. Adenocarcinoma of the colon occurs adjacent to the urine inlet. It is completely prevented by proximal diversion of the feces, implying that fecal carcinogens are activated locally by the urine or the urothelium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crissey, M M -- Steele, G D -- Gittes, R F -- New York, N.Y. -- Science. 1980 Mar 7;207(4435):1079-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355272" target="_blank"〉PubMed〈/a〉

    Impaired brain growth in neonatal rats exposed to ethanol (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-05-16
    Description: Infant rat pups, fed through intragastric cannulas from postnatal day 4 through day 18, showed a 19 percent reduction in total brain weight when ethanol was included in their diet on days 4 through 7. This reduction in brain weight occurred even though body growth in the experimental rats was equal to that of their littermate controls. The ethanol-exposed animals were markedly hypoactive during the period of drug administration, then displayed gross body tremors for 3 to 5 days. Throughout the study, the animals treated with ethanol had poor motor coordination and were hyperresponsive. These brain and behavioral effects appear similar to those seen in fetal alcohol syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diaz, J -- Samson, H H -- New York, N.Y. -- Science. 1980 May 16;208(4445):751-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7189297" target="_blank"〉PubMed〈/a〉

    Asymmetrically permeable membrane channels in cell junction (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-15
    Description: Asymmetric membrane junctions were formed in culture by pairing two cell types which, in their respective homologous junctions, have cell-cell channels of different permselectivities. The channels in the asymmetric junction, presumably made of unequal channel precursors, displayed directional permselectivity; fluorescent labeled glutamic acid (700 daltons), but not smaller and less polar permeant molecules, traversed the junction more readily in one direction than in the other. The favored direction was the one where the permeant passed first through the cell membrane that would have the less restrictive channels in a homologous junction. This directional selectivity requires no electric field across the junction and is thus distinct from a rectifying junction. The physiological potential of such directional molecular sieving for partitioning communication between tissue cells of different function and developmental fate are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flagg-Newton, J L -- Loewenstein, W R -- New York, N.Y. -- Science. 1980 Feb 15;207(4432):771-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352287" target="_blank"〉PubMed〈/a〉

    Cross-linking of lens crystallins in a photodynamic system: a process mediated by singlet oxygen (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-13
    Description: In a dye-sensitized photooxidation system, lens crystallin polypeptides become cross-linked, and a blue fluorescence that is associated with the proteins is produced. These changes are similar to those seen in vivo in the aging human lens. Evidence implicating singlet oxygen as the causative agent of the effects in vitro is presented, and the possibility that this species may play a role in aging and cataractogenesis in vivo is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goosey, J D -- Zigler, J S Jr -- Kinoshita, J H -- New York, N.Y. -- Science. 1980 Jun 13;208(4449):1278-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375939" target="_blank"〉PubMed〈/a〉

    Sodium-induced elevation of blood pressure in the anephric state (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-22
    Description: Normotensive anephric rats infused with 2 milliliters of a hyperosmolar solution of either sodium chloride or mannitol showed an increase in arterial pressure that was very pronounced with the sodium chloride and that could be partly abolished by administration of an antagonist to the vasopressor action of antidiuretic hormone (ADH). Rats with congenital ADH deficiency subjected to the same treatment showed smaller increments in arterial pressure that remained unchanged after administration of the ADH antagonist. Expansion of intravascular fluid volume was similar in all four groups and bore no correlation to the change in arterial pressure. It is concluded that about half of the increase in blood pressure induced by saline was attributable to the vasopressor effect of stimulated ADH and the remainder to an additional sodium-related factor, since it was more pronounced in the saline-infused than in the mannitol-infused groups. Expansion of the intravascular volume per se could only account for a minimal part of the increment in pressure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hatzinikolaou, P -- Gavras, H -- Brunner, H R -- Gavras, I -- New York, N.Y. -- Science. 1980 Aug 22;209(4459):935-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403861" target="_blank"〉PubMed〈/a〉

    Human hepatocellular carcinoma cell lines secrete the major plasma proteins and hepatitis B surface antigen (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-25
    Description: Analysis of the cell culture fluid from two new human hepatoma-derived cell lines reveals that 17 of the major human plasma proteins are synthesized and secreted by these cells. One of these cell lines, Hep 3B, also produces the two major polypeptides of the hepatitis B virus surface antigen. When Hep 3B in injected into athymic mice, metastatic hepatocellular carcinomas appear. These cell lines provide experimental models for investigation of plasma protein biosynthesis and the relation of the hepatitis B viru genome to tumorigenicity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knowles, B B -- Howe, C C -- Aden, D P -- New York, N.Y. -- Science. 1980 Jul 25;209(4455):497-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6248960" target="_blank"〉PubMed〈/a〉

    Persistence of crystallin messenger RNA's with reduced translation in hereditary cataracts in mice (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-21
    Description: In vitro translation experiments showed that the lens fiber cells of two hereditary cataracts in mice (Nakano and Philly) possessed a full complement of crystallin messenger RNA's, despite severely reduced synthesis of crystallin in these cells. The reduction in synthesis in the lens fiber cells correlated with the increase in Na+ and the decrease in K+, which occurs during cataractogenesis. In contrast to the fiber cells, the epithelial cells continued to synthesize crystallins in the cataractous lenses. Crystallin synthesis was stimulated in the fiber cells by raising the K+ concentration and lowering the Na+ concentration in the cultured lenses. The reduction in crystallin synthesis in the initial stages of cataractogenesis in the Nakano and Philly lenses thus appears to be due to poor utilization of crystallin messenger RNA's in the fiber cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shinohara, T -- Piatigorsky, J -- New York, N.Y. -- Science. 1980 Nov 21;210(4472):914-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434006" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-08-29
    Description: Prostaglandins of the A series strongly inhibit the production of Sendai virus in African green monkey kidney cells and are able to prevent the establishment of persistent infection ("carrier" state). This action is specific for prostaglandin A and is not due to alteration in the host cell metabolism or in the virus infectivity. The possibility that this effect is mediated by interferon is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Santoro, M G -- Benedetto, A -- Carruba, G -- Garaci, E -- Jaffe, B M -- New York, N.Y. -- Science. 1980 Aug 29;209(4460):1032-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6157190" target="_blank"〉PubMed〈/a〉

    Type II collagen-induced autoimmune endolymphatic hydrops in guinea pig (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-10-07
    Description: Endolymphatic hydrops was induced in guinea pigs by immunizing them with native bovine type II collagen. Histopathologic changes consisted of moderate extension of the Reissner's membrane, spiral ganglion degeneration, atrophied organ of Corti, and mild atrophy of the surface epithelium in the endolymphatic duct. These findings suggest that an immune response directed against type II collagen--a type of collagen found in the membranous labyrinth, subepithelial layer of the endolymphatic duct, spiral ligament, and enchondral layer of the otic capsule--may induce endolymphatic hydrops.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoo, T J -- Yazawa, Y -- Tomoda, K -- Floyd, R -- New York, N.Y. -- Science. 1983 Oct 7;222(4619):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6623056" target="_blank"〉PubMed〈/a〉
