    Expression of T cell antigen receptor heterodimers in a lipid-linked form (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-10
    Description: The interaction of the T cell receptor for antigen (TCR) with its antigen-major histocompatibility complex ligand is difficult to study because both are cell surface multimers. The TCR consists of two chains (alpha and beta) that are complexed to the five or more nonpolymorphic CD3 polypeptides. A soluble form of the TCR was engineered by replacing the carboxyl termini of alpha and beta with signal sequences from lipid-linked proteins, making them susceptible to enzymatic cleavage. In this manner, TCR heterodimers can be expressed independently of the CD3 polypeptides and in significant quantities (0.5 milligram per week). This technique seems generalizable to biochemical and structural studies of many other cell surface molecules as well.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, A Y -- Devaux, B -- Green, A -- Sagerstrom, C -- Elliott, J F -- Davis, M M -- New York, N.Y. -- Science. 1990 Aug 10;249(4969):677-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford University School of Medicine, CA 94305-5402.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1696397" target="_blank"〉PubMed〈/a〉

    Identity of inositol 1,2-cyclic phosphate 2-phosphohydrolase with lipocortin III (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-05-04
    Description: The amino acid sequences of three fragments of cyanogen bromide-digested human placental inositol 1,2-cyclic phosphate 2-phosphohydrolase, an enzyme of the phosphatidylinositol signaling pathway, are identical to sequences within lipocortin III, a member of a family of homologous calcium- and phospholipid-binding proteins that do not have defined physiological functions. Lipocortin III has also been previously identified as placental anticoagulant protein III (PAP III) and calcimedin 35 alpha. Antibodies to PAP III detected PAP III and inositol 1,2-cyclic phosphate 2-phosphohydrolase with identical reactivity on immunoblotting. In addition, inositol 1,2-cyclic phosphate 2-phosphohydrolase was stimulated by the same acidic phospholipids that bind lipocortins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ross, T S -- Tait, J F -- Majerus, P W -- HLBI 14147/HL/NHLBI NIH HHS/ -- HLBI 16634/HL/NHLBI NIH HHS/ -- HLBI 40801/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1990 May 4;248(4955):605-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Washington University School of Medicine, St Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2159184" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1990-04-06
    Description: A review of methodologically sound studies of the psychological responses of U.S. women after they obtained legal, nonrestrictive abortions indicates that distress is generally greatest before the abortion and that the incidence of severe negative responses is low. Factors associated with increased risk of negative response are consistent with those reported in research on other stressful life events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adler, N E -- David, H P -- Major, B N -- Roth, S H -- Russo, N F -- Wyatt, G E -- New York, N.Y. -- Science. 1990 Apr 6;248(4951):41-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2181664" target="_blank"〉PubMed〈/a〉

    Reproductive behavior and health in consanguineous marriages (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-10
    Description: In many regions of Asia and Africa, consanguineous marriages currently account for approximately 20 to 50% of all unions, and preliminary observations indicate that migrants from these areas continue to contract marriages with close relatives when resident in North America and Western Europe. Consanguinity is associated with increased gross fertility, due at least in part to younger maternal age at first livebirth. Morbidity and mortality also may be elevated, resulting in comparable numbers of surviving offspring in consanguineous and nonconsanguineous families. With advances in medicine and public health, genetic disorders will account for an increased proportion of disease worldwide. Predictably, this burden will fall more heavily on countries and communities in which consanguinity is strongly favored, as the result of the expression of deleterious recessive genes. However, studies conducted in such populations indicate that the adverse effects associated with inbreeding are experienced by a minority of families.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bittles, A H -- Mason, W M -- Greene, J -- Rao, N A -- New York, N.Y. -- Science. 1991 May 10;252(5007):789-94.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉King's College, University of London.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2028254" target="_blank"〉PubMed〈/a〉

    Changes in the sensory processing of olfactory signals induced by birth in sheep (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-05-08
    Description: After giving birth, sheep and many other species form a selective bond with their offspring based on the sense of smell. Processing of olfactory signals is altered to allow the animals to perform this selective recognition. Lamb odors have little effect on either neurotransmitter release or electrical activity of neurons in the olfactory bulb before birth. However, after birth there is an increase in the number of mitral cells, the principal cells of the olfactory bulb, that respond to lamb odors, which is associated with increased cholinergic and noradrenergic neurotransmitter release. Selective recognition of lambs is accompanied by increased activity of a subset of mitral cells and release of glutamate and gamma-aminobutyric acid (GABA) from the dendrodendritic synapses between the mitral and granule cells. The relation between the release of each transmitter after birth also suggests an increased efficacy of glutamate-evoked GABA release.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kendrick, K M -- Levy, F -- Keverne, E B -- New York, N.Y. -- Science. 1992 May 8;256(5058):833-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Agricultural and Food Research Council, Institute of Animal Physiology and Genetics Research, Babraham, Cambridge, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589766" target="_blank"〉PubMed〈/a〉

    Selective transmission of human immunodeficiency virus type-1 variants from mothers to infants (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-02-28
    Description: Multiple human immunodeficiency virus type-1 sequences from the V3 and V4-V5 regions of the envelope gene were analyzed from three mother-infant pairs. The infants' viral sequences were less diverse than those of their mothers. In two pairs, a proviral form infrequently found in the mother predominated in her infant. A conserved N-linked glycosylation site within the V3 region, present in each mother's sequence set, was absent in all of the infants' sequence sets. These findings demonstrate that a minor subset of maternal virus is transmitted to the infant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolinsky, S M -- Wike, C M -- Korber, B T -- Hutto, C -- Parks, W P -- Rosenblum, L L -- Kunstman, K J -- Furtado, M R -- Munoz, J L -- AI-32535/AI/NIAID NIH HHS/ -- HD26619-01/HD/NICHD NIH HHS/ -- P01-25569/PHS HHS/ -- New York, N.Y. -- Science. 1992 Feb 28;255(5048):1134-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Northwestern University Medical School, Chicago, IL 60611.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1546316" target="_blank"〉PubMed〈/a〉

    A class I antigen, HLA-G, expressed in human trophoblasts (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-04-13
    Description: The alpha chain of the human histocompatibility antigen HLA-G was identified as an array of five 37- to 39-kilodalton isoforms by the use of two-dimensional gel electrophoresis. Both cell-associated and secreted HLA-G antigens are prominent in first trimester villous cytotrophoblasts and are greatly reduced in third trimester cytotrophoblasts. Allelic variation was not detected, an indication that HLA-G is not obviously polymorphic in cytotrophoblasts. Among the following choriocarcinoma cell lines studied, HLA-G is expressed in JEG but not in Jar or BeWo. Expression of endogenous HLA-G genes has not been found in normal lymphoid cells. Thus, HLA-G is subject to both cell type-specific and developmental regulation and is expressed in early gestation human cytotrophoblasts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kovats, S -- Main, E K -- Librach, C -- Stubblebine, M -- Fisher, S J -- DeMars, R -- AI-15586/AI/NIAID NIH HHS/ -- HD-24495/HD/NICHD NIH HHS/ -- P0I HD-24180/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1990 Apr 13;248(4952):220-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Oncology, University of Wisconsin, Madison 53706.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2326636" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-30
    Description: Mice have an olfactory (pheromone) recognition memory located at the first relay in the sensory system. It is acquired with one-trial learning, contingent upon norepinephrine activation at mating, and lasts for several weeks. The mechanism involves Hebbian (association-dependent) changes in synaptic efficacy at dendrodendritic synapses in the accessory olfactory bulb. As a result of this memory, males made familiar by mating are recognized by the females, thereby mitigating pregnancy block. Such a memory function is biologically important to the female, as it is required to sustain pregnancy in the presence of her stud male's odors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brennan, P -- Kaba, H -- Keverne, E B -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1223-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sub-Department of Animal Behaviour, University of Cambridge, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2147078" target="_blank"〉PubMed〈/a〉

    Effect of light chain V region duplication on IgG oligomerization and in vivo efficacy (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-03
    Description: A human immunoglobulin G1 (IgG1) antibody oligomer was isolated from a transfected myeloma cell line that produced a monoclonal antibody to group B streptococci. Compared to the IgG1 monomer, the oligomer was significantly more effective at protecting neonatal rats from infection in vivo. The oligomer was also shown to cross the placenta and to be stable in neonatal rats. Immunochemical analysis and complementary DNA sequencing showed that the transfected cell line produced two distinct kappa light chains: a normal light chain (Ln) with a molecular mass of 25 kilodaltons and a 37-kilodalton species (L37), the domain composition of which was variable-variable-constant (V-V-C). Cotransfection of vectors encoding the heavy chain and L37 resulted in production of oligomeric IgG.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shuford, W -- Raff, H V -- Finley, J W -- Esselstyn, J -- Harris, L J -- New York, N.Y. -- Science. 1991 May 3;252(5006):724-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immune Sciences, Bristol-Myers Squibb Pharmaceutical Research Institute-Seattle, WA 98121.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1902593" target="_blank"〉PubMed〈/a〉

    Analysis of junctional diversity during B lymphocyte development (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-09
    Description: Immunoglobulin rearrangement is central to generating antibody diversity because of heterogeneity generated during recombination by deletion or addition of nucleotides at coding joints by the recombinase machinery. Examination of these junctional modifications revealed that the addition of nongermline-encoded nucleotides was more prevalent in adult versus fetal B cells, thus partially limiting the fetal antibody repertoire. In contrast, deletion of nucleotides occurs equivalently in B cells at different stages of development and at different points in B cell ontogeny. Finally, the bias in murine immunoglobulins for one DH segment reading frame occurs at the DHJH intermediate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meek, K -- New York, N.Y. -- Science. 1990 Nov 9;250(4982):820-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2237433" target="_blank"〉PubMed〈/a〉

    Linkage of early-onset familial breast cancer to chromosome 17q21 (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-12-21
    Description: Human breast cancer is usually caused by genetic alterations of somatic cells of the breast, but occasionally, susceptibility to the disease is inherited. Mapping the genes responsible for inherited breast cancer may also allow the identification of early lesions that are critical for the development of breast cancer in the general population. Chromosome 17q21 appears to be the locale of a gene for inherited susceptibility to breast cancer in families with early-onset disease. Genetic analysis yields a lod score (logarithm of the likelihood ratio for linkage) of 5.98 for linkage of breast cancer susceptibility to D17S74 in early-onset families and negative lod scores in families with late-onset disease. Likelihood ratios in favor of linkage heterogeneity among families ranged between 2000:1 and greater than 10(6):1 on the basis of multipoint analysis of four loci in the region.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, J M -- Lee, M K -- Newman, B -- Morrow, J E -- Anderson, L A -- Huey, B -- King, M C -- CA27632/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1990 Dec 21;250(4988):1684-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Public Health, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2270482" target="_blank"〉PubMed〈/a〉

    A mechanism for virilization of female spotted hyenas in utero (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-25
    Description: Female spotted hyenas exhibit male-like genitalia and dominance over males. Hyena ovarian tissues incubated in vitro produced large quantities of the steroid hormone precursor androstenedione. The activity of aromatase, which converts androstenedione to estrogen, was one-twentieth as great in hyena versus human placental homogenates. In comparison, the activity of 17 beta-hydroxysteroid dehydrogenase, which converts androstenedione to testosterone, was equal in the two homogenates. The limited aromatase activity may allow the hyena placenta to convert high circulating concentrations of androstenedione to testosterone, which results in virilization of the fetal external genitalia and possibly destruction of fetal ovarian follicles. Androstenedione production by residual ovarian stromal cells during reproductive life accounts for the epigenetic transmission of virilization in female spotted hyenas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yalcinkaya, T M -- Siiteri, P K -- Vigne, J L -- Licht, P -- Pavgi, S -- Frank, L G -- Glickman, S E -- CA-39825/CA/NCI NIH HHS/ -- MH-39917/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1993 Jun 25;260(5116):1929-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Obstetrics, Gynecology, University of California School of Medicine, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8391165" target="_blank"〉PubMed〈/a〉

    Stimulation and inhibition of angiogenesis by placental proliferin and proliferin-related protein (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-02
    Description: In many mammalian species, the placenta is the site of synthesis of proteins in the prolactin and growth hormone family. Analysis of two such proteins, proliferin (PLF) and proliferin-related protein (PRP), revealed that they are potent regulators of angiogenesis; PLF stimulated and PRP inhibited endothelial cell migration in cell culture and neovascularization in vivo. The mouse placenta secretes an angiogenic activity during the middle of pregnancy that corresponds primarily to PLF, but later in gestation releases a factor that inhibits angiogenesis, which was identified as PRP. Incubation of placental tissue with PLF led to the specific binding of this hormone to capillary endothelial cells. Thus PLF and PRP may regulate the initiation and then the cessation of placental neovascularization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jackson, D -- Volpert, O V -- Bouck, N -- Linzer, D I -- CA52750/CA/NCI NIH HHS/ -- HD24518/HD/NICHD NIH HHS/ -- HD29962/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1581-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Molecular Biology, and Cell Biology, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7527157" target="_blank"〉PubMed〈/a〉

    Malaria pathogenesis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-24
    Description: Malaria is a disease caused by repeated cycles of growth of the parasite Plasmodium in the erythrocyte. Various cellular and molecular strategies allow the parasite to evade the human immune response for many cycles of parasite multiplication. Under certain circumstances Plasmodium infection causes severe anemia or cerebral malaria; the expression of disease is influenced by both parasite and host factors, as exemplified by the exacerbation of disease during pregnancy. This article provides an overview of malaria pathogenesis, synthesizing the recent field, laboratory, and epidemiological data that will lead to the development of strategies to reduce mortality and morbidity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, L H -- Good, M F -- Milon, G -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1878-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Malaria Research, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009217" target="_blank"〉PubMed〈/a〉

    Maternal rescue of transforming growth factor-beta 1 null mice (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-24
    Description: Maternal sources of transforming growth factor-beta 1 (TGF-beta 1) are shown here to contribute to the normal appearance and perinatal survival of TGF-beta 1 null newborn mice. Labeled TGF-beta 1 crossed the placenta and was recovered intact from various tissues after oral administration to mouse pups. TGF beta-1 protein was also detected in cells recovered from breast milk. In immunohistochemical analyses, TGF-beta 1 null embryos and null newborn pups born to TGF-beta 1 heterozygotes stained positive for TGF-beta 1, whereas those born to a null female were negative and had severe cardiac abnormalities. These results suggest an important role for maternal sources of TGF-beta 1 during development and, more generally, provide evidence for maternal rescue of targeted gene disruption in the fetus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Letterio, J J -- Geiser, A G -- Kulkarni, A B -- Roche, N S -- Sporn, M B -- Roberts, A B -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1936-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Chemoprevention, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009224" target="_blank"〉PubMed〈/a〉

    Induction of an olfactory memory by the activation of a metabotropic glutamate receptor (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-08
    Description: Female mice form an olfactory memory of male pheromones at mating; exposure to the pheromones of a strange male after that mating will block pregnancy. The formation of this memory is mediated by the accessory olfactory system, in which an increase in norepinephrine after mating reduces inhibitory transmission of gamma-aminobutyric acid from the granule cells to the mitral cells. This study shows that the activation of mGluR2, a metabotropic glutamate receptor that suppresses the gamma-aminobutyric acid inhibition of the mitral cells, permits the formation of a specific olfactory memory without the occurrence of mating by infusion of mGluR2 agonists into the female's accessory olfactory bulb. This memory faithfully reflects the memory formed at mating.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaba, H -- Hayashi, Y -- Higuchi, T -- Nakanishi, S -- New York, N.Y. -- Science. 1994 Jul 8;265(5169):262-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, Kochi Medical School, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023145" target="_blank"〉PubMed〈/a〉

    Description: The highly selective, enzyme-activated, irreversible inhibitor of L-ornithine decarboxylase, DL-alpha-difluoromethylornithine, suppresses the increase in uterine L-ornithine decarboxylase activity associated with early embryogenesis in the mouse and arrests embryonic development at that stage. Contragestational effects were confirmed in the rat and rabbit. An increase in L-ornithine decarboxylase activity that leads to a rapid increase in putrescine concentration appears to be essential during a critical period after implantation for continued mammalian embryonal growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fozard, J R -- Part, M L -- Prakash, N J -- Grove, J -- Schechter, P J -- Sjoerdsma, A -- Koch-Weser, J -- New York, N.Y. -- Science. 1980 May 2;208(4443):505-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6768132" target="_blank"〉PubMed〈/a〉

    Dorsal root ganglion neurons are destroyed by exposure in utero to maternal antibody to nerve growth factor (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-21
    Description: Rats and guinea pigs, when immunized with mouse nerve growth factor, produce antibodies that cross-react with their own nerve growth factor. The antibodies reach developing offspring of these animals both prenatally (rats and guinea pigs) and postnatally (rats). Depriving the fetus of nerve growth factor in this way results in the destruction of up to 85 percent of dorsal root ganglion neurons as well as destruction of sympathetic neurons.

    Maternal glucocorticoid hormones influence neurotransmitter phenotypic expression in embryos (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-10-31
    Description: Treatment of pregnant rats with reserpine prevented the normal disappearance of catecholamine fluorescence in presumptive neuroblasts of the embryonic gut. These cells normally express the noradrenergic phenotype transiently during embryonic development. The effect of reserpine was reproduced by treating mothers with hydrocortisone acetate. Moreover, the reserpine effect was blocked by treatment with dexamethasone, which inhibits the stress-induced increase in plasma glucocorticoids, and by mitotone, which causes adrenocortical cytolysis. It is concluded that reserpine, through the mediation of maternal glucocorticoid hormones, alters the phenotypic expression of these embryonic neuroblasts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jonakait, G M -- Bohn, M C -- Black, I B -- HD 12108/HD/NICHD NIH HHS/ -- NS 06400/NS/NINDS NIH HHS/ -- NS 10259/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 31;210(4469):551-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7423206" target="_blank"〉PubMed〈/a〉

    High-molecular-weight immunoreactive beta-endorphin in extracts of human placenta is a fragment of immunoglobulin G (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-11
    Description: A high-molecular-weight protein with beta-endorphin- and adrenocorticotropin-immunoreactivities was isolated from extracts of human placenta after several purification steps, including immunoadsorption with a well-characterized antiserum raised to beta-endorphin. This protein was identified as the heavy chain of the human immunoglobulin class IgG1. These results have led to the recognition of homologies in the amino acid sequences of these physiologically unrelated molecules. They also suggest caution in accepting immunological competence as the sole criterion of the chemical identity of a ligand.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Julliard, J H -- Shibasaki, T -- Ling, N -- Guillemin, R -- New York, N.Y. -- Science. 1980 Apr 11;208(4440):183-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6244620" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-07
    Description: Nuclear receptors for both estradiol and progesterone were present in twofold higher concentrations in implantation sites than in nonimplantation regions of the endometrium of 6-day pregnant rats. Decidualization in the absence of an embryo was not accompanied by a similar increase in the concentration of nuclear receptors. Moreover, this difference in receptor distribution between the implantation and nonimplantation areas persisted when a major part of the maternal supply of sex steroids was suppressed by ovariectomy on day 5 of pregnancy. These results support the hypothesis that steroids originating from the embryo affect the endometrial implantation site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Logeat, F -- Sartor, P -- Hai, M T -- Milgrom, E -- New York, N.Y. -- Science. 1980 Mar 7;207(4435):1083-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355273" target="_blank"〉PubMed〈/a〉

    alpha-Lactalbumin-casein induction in virgin mouse mammary explants: dose-dependent differential action of cortisol (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-21
    Description: The interplay of insulin, cortisol, and prolactin induces synthesis of casein and alpha-lactalbumin in cultured mammary explants from mature virgin mice. A striking difference has been found between the optimal concentrations of cortisol required for maximal induction of the two milk proteins in vitro: 3 x 10(-8) molar for alpha-lactalbumin and 3 x 10(-6) molar for casein. Moreover, 10(-7) to 10(-5) molar cortisol caused progressive inhibition of alpha-lactalbumin accumulation. Such differential actions of cortisol may partly account for the asynchronous synthesis of the two proteins during pregnancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ono, M -- Oka, T -- New York, N.Y. -- Science. 1980 Mar 21;207(4437):1367-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6986657" target="_blank"〉PubMed〈/a〉

    Inverse relation between low-density lipoprotein-cholesterol and dehydroisoandrosterone sulfate in human fetal plasma (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-05-02
    Description: A striking inverse correlation was found in umbilical cord plasma between the concentrations of dehydroisoandrosterone sulfate and low-density lipoprotein (LDL)-cholesterol but not high-density lipoprotein-cholesterol or very low density lipoprotein-cholesterol. Dehydroisoandrosterone sulfate is a major secretory product of the human fetal adrenal and the principal precursor of placental estrogen production. The data suggest that the concentrations for LDL-cholesterol in fetal plasma are influenced by the rate of utilization of LDL-cholesterol by the fetal adrenal for steroidogenesis and are not necessarily related to a genetic predisposition for hypercholesterolemia or other lipoprotein disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, C R Jr -- Simpson, E R -- Bilheimer, D W -- Leveno, K -- Carr, B R -- MacDonald, P C -- New York, N.Y. -- Science. 1980 May 2;208(4443):512-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6445079" target="_blank"〉PubMed〈/a〉

    Description: The binding of [6-alanine]gonadotropin-releasing hormone to pituitary plasma membranes increased threefold between metestrus and early proestrus in female rats. Receptor numbers fell rapidly on the afternoon of proestrus coincident with the preovulatory gonadotropin surge. The numbers of receptors for gonadotropin-releasing hormone were positively correlated with concentrations of estradiol in serum; this pattern may be a necessary component of increased pituitary sensitivty to gonadotropin-releasing hormone observed during proestrus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Savoy-Moore, R T -- Schwartz, N B -- Duncan, J A -- Marshall, J C -- New York, N.Y. -- Science. 1980 Aug 22;209(4459):942-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6250218" target="_blank"〉PubMed〈/a〉

    Description: The serum of lactating rats that have never been infected with the protozoan parasite Trypanosoma lewisi contains a rheumatoid factor-like immunoglobulin M (IgM). This IgM amplifies a specific immunoglobulin G (IgG) response to the parasite and accounts for the unusual resistance of previously uninfected lactating rats and their suckling pups to infection with T. lewisi. A similar rheumatoid factor-like IgM, which is induced late in the usual course of infection with T. lewisi in nonlactating rats, amplifies an earlier IgM response and terminates the infection. To our knowledge, this is the first description of a rheumatoid factor, which is classified as an autoimmune antibody, acting in a protective manner.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clarkson, A B Jr -- Mellow, G H -- New York, N.Y. -- Science. 1981 Oct 9;214(4517):186-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7025211" target="_blank"〉PubMed〈/a〉

    Description: Ovaries removed from New Zealand White rabbits were perfused and exposed to gonadotropin in vitro. The ova ovulated in vitro (N = 56) were recovered and cultured and then transferred to the oviducts of six previously mated Dutch Belted hosts. Twelve of the resulting 36 offspring (33.3 percent) were white. In control matings between 12 Dutch Belted females (six randomly selected and the six hosts) and New Zealand White males, only one of 80 (1.2 percent) offspring was white. These data indicate that ova ovulated in vitro can be transferred to the oviduct of a host rabbit where they may be fertilized and after implantation may develop into viable embryos.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kobayashi, Y -- Santulli, R -- Wright, K H -- Wallach, E E -- HD-05948/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 4;213(4512):1127-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7268420" target="_blank"〉PubMed〈/a〉

    Differentiation of respiratory and abortigenic isolates of equine herpesvirus 1 by restriction endonucleases (1981)

    Details
    Publication Date: 1981-10-30
    Description: Viruses classified by immunologic criteria as equine herpesvirus 1 cause respiratory disease and abortion in horses. Restriction endonuclease analyses of the DNA's of viruses from animals with respiratory disease and from aborted fetuses show that the patterns for respiratory viruses, while similar to each other, are entirely different from the patterns for fetal viruses. It is therefore proposed that the DNA restriction endonuclease patterns of fetal and respiratory viruses analyzed in this study be designated as prototypic of equine herpesvirus 1 and 4, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Studdert, M J -- Simpson, T -- Roizman, B -- CA 08494/CA/NCI NIH HHS/ -- CA 09241/CA/NCI NIH HHS/ -- CA 19264/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):562-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6270790" target="_blank"〉PubMed〈/a〉

    Description: Erythrocytes infected with the late stages of the human malarial parasite Plasmodium falciparum became attached to a subpopulation of cultured human endothelial cells by knoblike protrusions on the surface of the infected erythrocytes. Infected erythrocytes did not bind to cultured fibroblasts; uninfected erythrocytes did not bind to either endothelial cells or fibroblasts.

    Description: Rat pups nursed by pregnant dams grow as fast as pups reared by dams that are not pregnant. Moreover, litters that were in utero during a lactation are as numerous at birth and grow as fast as pups developing in a nonlactating, pregnant mother. These litters continue to grow as fast as pups born to nonlactating dams whether or not the first litter remains after the birth of the second litter. When pregnant and lactating dams have a restricted food supply, some dams are capable of extending the duration of their pregnancies by over 2 weeks past that of nonlactating, pregnant dams. This facultative prolongation of pregnancy apparently allows females to carry normal litters to term.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Woodside, B -- Wilson, R -- Chee, P -- Leon, M -- New York, N.Y. -- Science. 1981 Jan 2;211(4477):76-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444451" target="_blank"〉PubMed〈/a〉

    Description: Female athymic nude mice and their phenotypically normal littermates were exposed transplacentally to ethylnitrosourea. Skin tumors (papillomas and sebaceous adenomas) developed on the nude mice with an almost tenfold greater incidence than on their haired littermates. Skin tumors were also induced on nude mice but not haired controls by direct intraperitoneal treatment with ethylnitrosourea.

    Reversal of morphine disruption of maternal behavior by concurrent treatment with the opiate antagonist naloxone (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-08
    Description: Rats whose pregnancies were surgically terminated on day 17 of gestation were injected with morphine, morphine plus naloxone hydrochloride, or saline, and then tested for maternal responsiveness toward foster young. Morphine treatment alone significantly disrupted the rate of onset and quality of maternal responsiveness. Concurrent administration of naloxone to morphine-injected rats reinstated the rapid onset of behavioral responsiveness toward foster young, such that the responsiveness of the rats treated with both morphine and naloxone was indistinguishable from that shown by saline-injected controls. The disruptive effects of morphine did not appear to result from a general reduction in activity levels as measured in an open-field apparatus. These findings suggest that the normal onset and maintenance of maternal behavior in the rat may be regulated by endogenous opiates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bridges, R S -- Grimm, C T -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):166-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123227" target="_blank"〉PubMed〈/a〉

    Description: A synthetic antagonist of luteinizing hormone-releasing hormone blocked ovulation in rats in a dose-dependent manner when given by gavage on the afternoon of proestrus. Ovulation was delayed for at least 1 day in all animals given 2 milligrams of antogonist and in some of the animals treated with 1 or 0.5 milligram.

The ethanol-induced impairment of umbilical circulation produced severe hypoxia and acidosis in the fetus; recovery occurred during the succeeding hour.

    Norethisterone, a major ingredient of contraceptive pills, is a suicide inhibitor of estrogen biosynthesis (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-03-05
    Description: Norethisterone (17 alpha-ethynyl-19-nortestosterone) is an effective irreversible inhibitor of estrogen synthetase (aromatase), the enzyme responsible for the conversion of androgens to estrogens, even at a 2 X 10(-6) molar concentration. This irreversible inactivation, which is directed toward the active site of aromatase and requires the cofactor-reduced nicotinamide adenine dinucleotide phosphate, is both time- and concentration-dependent. Ethisterone (17 alpha-ethynyltestosterone), in contrast, is not a suicide inhibitor of aromatase even at concentrations of 10(-4) molar.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Osawa, Y -- Yarborough, C -- HDO4945/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 5;215(4537):1249-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058343" target="_blank"〉PubMed〈/a〉

    Description: The sexual behavior of rhesus monkeys in 15 male-female pairings was observed in both a large and a small area during the follicular and luteal phases of the female's cycle. Males ejaculated in all tests at the follicular phase of the female's cycle and in 53 percent of tests at the luteal phase. However, a significant decline in ejaculation during tests at the luteal phase occurred in the large, but not in the small area. Thus the degree to which the pair's sexual behavior was influenced by the female's hormonal state depended on the spatial conditions of the test.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wallen, K -- MH35835/MH/NIMH NIH HHS/ -- RR-00165/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 23;217(4557):375-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7201164" target="_blank"〉PubMed〈/a〉

    Human fetal movement: spontaneous oscillations near one cycle per minute (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: Spectral analysis of spontaneous fluctuations in human fetal movement revealed strong oscillations at frequencies between 0.24 and 0.90 cycle per minute, which are much higher than those of the cyclic alternation of quiet and active states in the fetus and neonate. Oscillations at frequencies up to 2.88 cycles per minute were also detected, but they were usually much weaker. The prominent peaks in the fetal movement spectra are in the frequency range of recently reported neonatal motor rhythms, and indicate the existence of a cyclic process controlling spontaneous motor output that oscillates near one cycle per minute and begins to function in utero.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robertson, S S -- Dierker, L J -- Sorokin, Y -- Rosen, M G -- M01RR00210/RR/NCRR NIH HHS/ -- P50HD11089/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1327-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146916" target="_blank"〉PubMed〈/a〉

    Regulation of carcinogen metabolism in the rat ovary by the estrous cycle and gonadotropin (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-03-25
    Description: The activity of 7,12-dimethylbenz[a]anthracene hydroxylase in the rat ovary is several times higher in the proestrous phase of the estrous cycle than in the estrous and metestrous plus diestrous phases. Administration of gonadotropin leads to a similar increase in the capacity of the ovary to metabolize xenobiotics. This variation in the activity of 7,12-dimethylbenz[a]anthracene hydroxylase during the estrous cycle may be related to the marked changes in the incidence of ovarian cancer during menopause and in women taking contraceptive pills.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bengtsson, M -- Rydstrom, J -- New York, N.Y. -- Science. 1983 Mar 25;219(4591):1437-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6681915" target="_blank"〉PubMed〈/a〉

    Description: Laetrile administered orally ot pregnant hamsters caused skeletal malformations in the offspring, but intravenous laetrile filed to result in embryopathic effects. Oral laetrile significantly increased in situ cyanide concentrations, while intravenous laetrile did not. Thiosulfate administration protected embryos from the teratogenic effects of oral laetrile. The embryopathic effects of oral laetrile appear to be due to cyanide released by bacterial beta-glucosidase activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willhite, C C -- New York, N.Y. -- Science. 1982 Mar 19;215(4539):1513-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063858" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-08-26
    Description: The rate of increase of population in less developed countries accelerated rapidly from 1850 to 1960 because of a rapid decline in mortality while fertility remained high. In the 1960's, the birth rate as a whole began to decline more rapidly than the death rate--very rapidly in some populations, most notably that of China, more gradually in others, and not at all in some of the poorest populations. The momentum of growth implies continued increase in populations for several decades even in countries where fertility has fallen the most, and very large additional increases where there has been no decline in the rate of childbearing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coale, A J -- New York, N.Y. -- Science. 1983 Aug 26;221(4613):828-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6879179" target="_blank"〉PubMed〈/a〉

    External human fertilization: an evaluation of policy (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-10-14
    Description: In vitro fertilization, in its first 5 years of use, has met minimum standards for efficacy and safety, as judged by published clinical reports. It is becoming more widely available as an approach for overcoming sterility in married couples and appears also to be gaining social acceptance in that context. Several technical options presented by the procedure, particularly storage of frozen embryos and embryo transfers involving third-party contributions, are less fully evaluated clinically and raise social, ethical, and legal questions that go beyond the original medical model for therapeutic intervention. The clinical success of in vitro fertilization and the options it affords call for careful policy consideration. Estimates of costs and of potential demand for and supply of services are provided and the current status of relevant policy in the United States and abroad is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grobstein, C -- Flower, M -- Mendeloff, J -- New York, N.Y. -- Science. 1983 Oct 14;222(4620):127-33.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6623063" target="_blank"〉PubMed〈/a〉

    Publication Date: 1984-09-21
    Description: The nervous system of mammals retains throughout the animals' life-span the ability to modify the number, nature, and level of activity of its synapses. Synaptic plasticity is most evident after injury to the nervous system, and the cellular and molecular mechanisms that make it possible are beginning to be understood. Transplantation of brain tissue provides a powerful approach for studying mechanisms of synaptic plasticity. In turn, understanding the response of the central nervous system to injury can be used to optimize transplant survival and integration with the host brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cotman, C W -- Nieto-Sampedro, M -- AG 00538/AG/NIA NIH HHS/ -- MH 19691/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1984 Sep 21;225(4668):1287-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6382610" target="_blank"〉PubMed〈/a〉

    Description: Exposing pregnant rats to carbon monoxide (150 parts per million) produced only minor reductions in the birth weights of the pups and gave no evidence of overt teratogenesis. However, behavioral evaluation of learning and memory processes in a two-way avoidance task suggested a functional deficit in the central nervous system of the exposed offspring. Multiple dependent measures and specific control groups confirmed that this deficit was independent of nonassociative or motivational alterations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mactutus, C F -- Fechter, L D -- ES 01589/ES/NIEHS NIH HHS/ -- ES 07094/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1984 Jan 27;223(4634):409-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6691152" target="_blank"〉PubMed〈/a〉

    Publication Date: 1984-02-17
    Description: Cell-free conditioned media from human T cells transformed by human T-cell leukemia-lymphoma virus (HTLV-I) were tested for the production of soluble biologically active factors, including several known lymphokines. The cell lines used were established from patients with T-cell leukemia-lymphoma and from human umbilical cord blood and bone marrow leukocytes transformed by HTLV-I in vitro. All of the cell lines liberated constitutively one or more of the 12 biological activities assayed. These included macrophage migration inhibitory factor (MIF), leukocyte migration inhibitory factor (LIF), leukocyte migration enhancing factor (MEF), macrophage activating factor (MAF), differentiation inducing factor (DIF), colony stimulating factor (CSF), eosinophil growth and maturation activity (eos. GMA), fibroblast activating factor (FAF), gamma-interferon and, in rare instances, T-cell growth factor (TCGF). Some cell lines produced interleukin 3 (IL-3), platelet-derived growth factor (PDGF), or B-cell growth factors (BCGF). Such cells should prove useful for the production of lymphokines and as sources of specific messenger RNA's for their genetic cloning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Salahuddin, S Z -- Markham, P D -- Lindner, S G -- Gootenberg, J -- Popovic, M -- Hemmi, H -- Sarin, P S -- Gallo, R C -- New York, N.Y. -- Science. 1984 Feb 17;223(4637):703-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6320367" target="_blank"〉PubMed〈/a〉
