    Description: Two human genes that are homologous to both the murine transforming gene (oncogene) v-raf and the chicken transforming gene v-mil have been mapped by means of human-rodent somatic cell hybrids to human chromosomes previously devoid of known oncogenes. One gene, c-raf-2, which appears to be a processed pseudogene, is located on chromosome 4. The other gene, c-raf-1, which appears to be the active gene, is located on chromosome 3 and has been regionally mapped by chromosomal in situ hybridization to 3p25. This assignment correlates with specific chromosomal abnormalities associated with certain human malignancies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bonner, T -- O'Brien, S J -- Nash, W G -- Rapp, U R -- Morton, C C -- Leder, P -- New York, N.Y. -- Science. 1984 Jan 6;223(4631):71-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6691137" target="_blank"〉PubMed〈/a〉

    Description: T-cell growth factor (TCGF) or interleukin-2 (IL-2), an immunoregulatory lymphokine, is produced by lectin- or antigen-activated mature T lymphocytes and in a constitutive manner by certain T-cell lymphoma cell lines. By means of a molecular clone of human TCGF and DNA extracted from a panel of somatic cell hybrids (rodent cells X normal human lymphocytes), the TCGF structural gene was identified on human chromosome 4. In situ hybridization of the TCGF clone to human chromosomes resulted in significant labeling of the midportion of the long arm of chromosome 4, indicating that the TCGF gene was located at band q26-28. Genomic DNA from a panel of hybrids prepared with HUT-102 B2 cells was examined with the same molecular clone. In this clone of cells, which produces human T-cell leukemia virus, the TCGF gene was also located on chromosome 4 and was apparently not rearranged. The homologous TCGF locus in the domestic cat was assigned to chromosome B1 by using a somatic cell hybrid panel that segregates cat chromosomes. Linkage studies as well as high-resolution G-trypsin banding indicate that this feline chromosome is partially homologous to human chromosome 4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seigel, L J -- Harper, M E -- Wong-Staal, F -- Gallo, R C -- Nash, W G -- O'Brien, S J -- New York, N.Y. -- Science. 1984 Jan 13;223(4632):175-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6318318" target="_blank"〉PubMed〈/a〉

    Description: The kidney, and to a slight extent the liver, of human fetuses were found to synthesize and secrete the alpha subunit common to glycoprotein hormones. Fetal lung and muscle did not synthesize this protein. Since fetal kidney and liver were previously found to synthesize beta chorionic gonadotropin, their ability to synthesize bioactive chorionic gonadotropin was also determined. The newly synthesized hormone bound to mouse Leydig cells and elicited a biological response: namely, the synthesis of testosterone. These results suggest that the human fetus may participate in metabolic homeostasis during its development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGregor, W G -- Kuhn, R W -- Jaffe, R B -- HD08478/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):306-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6682243" target="_blank"〉PubMed〈/a〉

    Description: Nondeletion forms of hereditary persistence of fetal hemoglobin may result from regulatory disorders of globin gene expression. The defects in two such conditions were localized by demonstrating a tight genetic linkage between the disorders and polymorphic restriction endonuclease sites within the beta-like globin gene complex. In one instance, the defect probably occurred outside the region of DNA between the epsilon- and beta-globin genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Old, J M -- Ayyub, H -- Wood, W G -- Clegg, J B -- Weatherall, D J -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):981-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6186021" target="_blank"〉PubMed〈/a〉

    Description: After more than 230 hours of practice in the laboratory, a subject was able to increase his memory span from 7 to 79 digits. His performance on other memory tests with digits equaled that of memory experts with lifelong training. With an appropriate mnemonic system, there is seemingly no limit to memory performance with practice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ericcson, K A -- Chase, W G -- Faloon, S -- New York, N.Y. -- Science. 1980 Jun 6;208(4448):1181-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375930" target="_blank"〉PubMed〈/a〉

    Description: The effects of marginal malnourishment , infections, and environmental chemicals on growth and reproductive success in Swiss-Webster white mice and wild deer mice were studied with fractional factorial designs. Interaction effects were discovered. For example, malnourished mice were more sensitive to virus exposure and environmental chemicals (a plant growth regulator or polychlorinated biphenyls). Since several commercial plant growth regulators also appear to suppress the immune system, these results cast doubt on the adequacy of current toxicity testing procedures in which factors are studied individually and not in combination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Porter, W P -- Hinsdill, R -- Fairbrother, A -- Olson, L J -- Jaeger, J -- Yuill, T -- Bisgaard, S -- Hunter, W G -- Nolan, K -- 5-T32-ES07015/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1984 Jun 1;224(4652):1014-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6426058" target="_blank"〉PubMed〈/a〉

    Description: The formulation of generalized models tracing the geometry and intensity of the synchrotron emission from precessing, twin, relativistic jets as projected on the plane of the sky is presented. It is shown that neither the shape of the image nor its relative intensities are altered by including the effects of a cosmological redshift and a relative velocity between the source and observer. The models are fitted to the available data for several quasars and radio galaxies and demonstrate the plausibility of the phenomenon. Probable selection effects are considered and diagnostics given for recognizing objects showing this behavior. In the radio galaxies considered, velocities up to about 0.2c and precession periods of 1,000,000 yr are deduced. In the QSOs investigated, velocities of 0.7c and greater are found and periods of order 10,000 yr. In some cases precession cone angles increase with time. Consequences in terms of lifetimes of QSO behavior and binary supermassive objects are discussed.

    Description: An area of 7.5 sq deg of the galactic plane at 70 microns have been surveyed with a 1-arcmin beam. The region lies between lII equals 10 deg and lII equals 16 deg and includes the M17 and W33 complexes. The weakest of the 42 sources detected had a flux density of 350 Jy at 70 microns. Detailed far-infrared, (C-12)O, (C-13)O, and radio continuum observations of the sources are presented. The derivation of the important physical parameters of the sources and their surrounding molecular clouds are discussed. The properties of the individual regions are also discussed and maps of selected sources are presented.

    Description: A direct measurement has been made of the spectrum (1180-1680 A) and Gould-latitude dependence of the local interstellar radiation field, over about one-third of the sky. The result is corrected to give expected values for the entire sky. The average local 1180-1680 A energy density is 5.8 x 10 to the -17th ergs/cu cm A. The surface brightness falls off toward high latitudes much more steeply than published models predict.
