    Description: The acquired immune deficiency syndrome (AIDS), which has recently occurred at increasing rates in homosexual men, intravenous drug users, and others, is characterized by the development of Kaposi's sarcoma and several opportunistic infections including pneumonia caused by Pneumocystis carinii. Serum samples from patients with AIDS and from matched and unmatched control subjects were examined for the presence of antibodies to cell membrane antigens associated with human T-cell leukemia virus. Nineteen of 75 of the AIDS patients had antibodies directed to surface antigens of Hut 102, a reference T lymphoid cell line infected with leukemia virus, as did two of the 336 control subjects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Essex, M -- McLane, M F -- Lee, T H -- Falk, L -- Howe, C W -- Mullins, J I -- Cabradilla, C -- Francis, D P -- 2T32CA09031/CA/NCI NIH HHS/ -- 5T32HL07523/HL/NHLBI NIH HHS/ -- CA 18216/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 20;220(4599):859-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6342136" target="_blank"〉PubMed〈/a〉

    Description: Markedly elevated nighttime concentrations of serotonin in rhesus monkey cerebrospinal fluid were reduced to daytime levels by exposing the monkeys to continuous light or to the beta-adrenergic antagonist propranolol. Nighttime elevations of melatonin in cerebrospinal fluid were also suppressed by propranolol and light. Serotonin released in large quantities at night appears to be regulated like melatonin, and may act as a cerebroventricular hormone to influence brain and pituitary function at night.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garrick, N A -- Tamarkin, L -- Taylor, P L -- Markey, S P -- Murphy, D L -- New York, N.Y. -- Science. 1983 Jul 29;221(4609):474-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6683428" target="_blank"〉PubMed〈/a〉

    Description: The acquired immune deficiency syndrome (AIDS) is characterized by T-lymphocyte dysfunction and is frequently accompanied by opportunistic infections and Kaposi's sarcoma. Human T-cell leukemia virus (HTLV) is associated with T-cell malignancies and can transform T lymphocytes in vitro. In an attempt to find evidence of HTLV infection in patients with AIDS, DNA from samples of peripheral blood lymphocytes from 33 AIDS patients was analyzed by Southern blot-hybridization with a radiolabeled cloned HTLV DNA probe. Analysis of DNA from both the fresh (uncultured) lymphocytes and from T cells cultured with T-cell growth factor revealed the presence of integrated HTLV proviral sequences in lymphocytes from two of the patients, both of whom had antibody to HTLV. The proviral sequences could not be detected in blood samples obtained from these individuals at a later date, consistent with the possibility that the population of infected cells had become depleted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelmann, E P -- Popovic, M -- Blayney, D -- Masur, H -- Sidhu, G -- Stahl, R E -- Gallo, R C -- New York, N.Y. -- Science. 1983 May 20;220(4599):862-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6601822" target="_blank"〉PubMed〈/a〉

    Description: Giardia lamblia, a common pathogenic intestinal parasite of humans, was rapidly killed by exposure to normal human milk in vitro. The killing did not depend on secretory immunoglobulin A. Entamoeba histolytica, the dysentery amoeba, was also killed by normal human milk. Giardia-cidal activity cochromatographed with an unusual lipase that is present in the milk of humans but not of lower mammals. Human milk may play a protective role in infants exposed to this parasite.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gillin, F D -- Reiner, D S -- Wang, C S -- AI19863/AI/NIAID NIH HHS/ -- HD14104/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 23;221(4617):1290-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6310751" target="_blank"〉PubMed〈/a〉

    Description: Behavior of squirrel monkeys, maintained by the termination of stimuli associated with electric shock, was suppressed by response-dependent shock delivery. The effects of pentobarbital on this behavior depended on whether monkeys had previously received morphine. In monkeys without experience with drugs, pentobarbital increased responding. In monkeys with recent experience with morphine, however, pentobarbital resulted in a smaller increase or decrease in responding. The rate-decreasing effects of pentobarbital after a history of morphine administration could be reversed by the administration of d-amphetamine. These findings suggest that the behavioral effects of abused drugs may depend on previous experience with other drugs, even when those drugs are from a different pharmacological class.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glowa, J R -- Barrett, J E -- DA 02658/DA/NIDA NIH HHS/ -- DA 02873/DA/NIDA NIH HHS/ -- MH 07658/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):333-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6682244" target="_blank"〉PubMed〈/a〉

    Description: The Lewy body, a histological hallmark of Parkinson's disease, is a filamentous inclusion residing most prominently in pigmented neurons of the brainstem. Immunocytochemical reactions of Lewy bodies were examined with antisera to several filamentous proteins of the nervous system and positive reactions were found with those against neurofilaments. An abnormal organization of the neuronal cytoskeleton may be a pathological feature of Parkinson's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldman, J E -- Yen, S H -- Chiu, F C -- Peress, N S -- AG 01136/AG/NIA NIH HHS/ -- NS 02476/NS/NINDS NIH HHS/ -- NS 17125/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Sep 9;221(4615):1082-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308771" target="_blank"〉PubMed〈/a〉

    Description: Young deaf children who were unable to acquire oral language naturally and who had not been exposed to a conventional manual language were found to use spontaneously a gesture system that has some of the structural characteristics of early child language. The structural aspects of this gesture system appeared to be neither modeled for the child by the gestures of an adult nor shaped by the responses of an adult. These findings suggest that the child may contribute to structural aspects of the system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldin-Meadow, S -- Mylander, C -- New York, N.Y. -- Science. 1983 Jul 22;221(4608):372-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6867713" target="_blank"〉PubMed〈/a〉

    Description: Cultured bronchial epithelial and fibroblastic cells from humans were used to study DNA damage and toxicity caused by formaldehyde. Formaldehyde caused the formation of cross-links between DNA and proteins, caused single-strand breaks in DNA, and inhibited the resealing of single-strand breaks produced by ionizing radiation. Formaldehyde also inhibited the unscheduled DNA synthesis that occurs after exposure of cells to ultraviolet irradiation or to benzo[a]pyrene diolexpoxide but at doses substantially higher than those required to inhibit the resealing of x-ray-induced single-strand breaks. Therefore, formaldehyde could exert its mutagenic and carcinogenic effects by both damaging DNA and inhibiting DNA repair.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grafstrom, R C -- Fornace, A J Jr -- Autrup, H -- Lechner, J F -- Harris, C C -- New York, N.Y. -- Science. 1983 Apr 8;220(4593):216-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828890" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Neutrophils, especially in acute infection or the myeloid leukemias, may shed platelet-sized particles that can readily be distinguished from true platelets because they contain neutrophil myeloperoxidase. This enzyme, unlike platelet peroxidase, is not inhibited by glutaraldehyde. The myeloperoxidase and acid hydrolase levels and continuous plasma membranes of these cell-like particles suggest that they are functional cellular entities. They further differ from platelets in that they contain nuclear remnants, occur in bacteria-laden pus and inflammatory exudates, are ingested by macrophages, and do not adhere to each other or aggregate. They could be involved in the immune response to pathogens or contribute to trauma and healing by facilitating deployment of neutrophil acid hydrolase, neutral protease, and myeloperoxidase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanker, J S -- Giammara, B L -- DE 02668/DE/NIDCR NIH HHS/ -- DE 05333/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 22;220(4595):415-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6301006" target="_blank"〉PubMed〈/a〉

    Description: Mice infected with reovirus type 1 develop an autoimmune polyendocrine disease. Spleen cells from these mice were fused with myeloma cells and the culture fluids were screened by indirect immunofluorescence for autoantibodies reactive with normal mouse tissues. A large panel of cloned, stable antibody-producing hybridomas has been obtained. Fourteen of the hybridomas make autoantibodies that react with cells in the islets of Langerhans, 24 with cells in the anterior pituitary, 11 with cells in gastric mucosa, and 5 with nuclei. Except for the antibodies to nuclei, the monoclonal autoantibodies are organ-specific. Some, however, show broad cross-species reactivity, recognizing similar antigenic determinants in mouse, rat, pig, and human organs, whereas other recognize determinants only in rodent tissues. Several of the antigens recognized by these monoclonal autoantibodies have been identified as hormones (for example, glucagon, growth hormone, and insulin).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haspel, M V -- Onodera, T -- Prabhakar, B S -- Horita, M -- Suzuki, H -- Notkins, A L -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):304-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6301002" target="_blank"〉PubMed〈/a〉

    Description: The size of the Epstein-Barr virus (EBV) nuclear antigen (EBNA) in cells infected with different EBV isolates varies directly with the size of the EBV triplet repeat array, IR3. The isolate with the largest IR3 fragment has approximately 170 more codons than the isolates with the smallest IR3 fragment; it encodes an EBNA which is approximately 17,000 daltons larger than the smallest EBNA. The EBV IR3 encodes part of a 2-kilobase exon of a latently infected cell messenger RNA which must be translated into a repetitive amino acid domain of EBNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hennessy, K -- Heller, M -- van Santen, V -- Kieff, E -- CA 17281/CA/NCI NIH HHS/ -- CA 19264/CA/NCI NIH HHS/ -- GM 07183/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Jun 24;220(4604):1396-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6304878" target="_blank"〉PubMed〈/a〉

    Description: Plasmids were constructed to direct synthesis of the human interferons IFN-alpha 1, IFN-alpha 2, and IFN-gamma in the yeast Saccharomyces cerevisiae. Expression of IFN genes containing coding sequences for secretion signals resulted in the secretion of IFN activity. A large proportion of the IFN-alpha 1 and IFN-alpha 2 isolated from the yeast cell growth media had the same amino termini as the natural mature interferons, suggesting a removal of the signal sequences identical to that of human cells. These results show that a lower eukaryote, such as yeast, can utilize and process a human signal sequence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hitzeman, R A -- Leung, D W -- Perry, L J -- Kohr, W J -- Levine, H L -- Goeddel, D V -- New York, N.Y. -- Science. 1983 Feb 11;219(4585):620-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6186023" target="_blank"〉PubMed〈/a〉

    Description: Influenza A viruses (subtype H1N1), recently isolated from turkeys in different areas of the United States, were determined to be closely related to strains typically associated with pigs. This conclusion was based on comparisons of H1N1 isolates from pigs, humans, ducks, and turkeys with polyclonal and monoclonal antibodies, RNA-RNA competitive hybridization, and replication studies. One of the H1N1 isolates from turkeys caused influenza in a laboratory technician, who displayed fever, respiratory illness, virus shedding, and seroconversion. These results suggest that turkeys as well as pigs are involved in the maintenance of these viruses and their transmission to humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hinshaw, V S -- Webster, R G -- Bean, W J -- Downie, J -- Senne, D A -- AI-02649/AI/NIAID NIH HHS/ -- AI-08831/AI/NIAID NIH HHS/ -- AI-16841/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Apr 8;220(4593):206-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6298942" target="_blank"〉PubMed〈/a〉

    Description: The eye movements of human subjects were experimentally modified while they were awake to determine the effect of waking experience on electroculographic activity during rapid eye movement (REM) sleep. After normal eye movements were monitored under controlled conditions, subjects spent 5 days wearing goggles that contained minification lenses and that curtailed vision to a 5 degree field. The amplitude and frequency of eye movements decreased when subjects were awake and increased during REM sleep; sleep stage durations and distributions were unaffected. Values returned to normal in the first 24 hours of recovery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herman, J H -- Roffwarg, H P -- MH 3414/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1983 Jun 3;220(4601):1074-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6844929" target="_blank"〉PubMed〈/a〉

    Description: A simple and efficient method of covalently coupling the strong chelator diethylenetriaminepentaacetic acid to proteins was developed for radiolabeling immunoglobulin G antibodies. After being coupled and labeled with indium-111, a monoclonal antibody to carcinoembryonic antigen retained its ability to bind to its antigen in vitro and in vivo. In nude mice with a human colorectal xenograft, 41 percent of the injected radioactivity became localized in each gram of xenograft at 24 hours compared with 9 percent for control antibody and 19 percent for radioiodinated antibody to carcinoembryonic antigen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hnatowich, D J -- Layne, W W -- Childs, R L -- Lanteigne, D -- Davis, M A -- Griffin, T W -- Doherty, P W -- 1 RO1 CA26968/CA/NCI NIH HHS/ -- 1 RO1 GM26780/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 May 6;220(4597):613-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836304" target="_blank"〉PubMed〈/a〉

    Description: The thickness of intact human red cell membrane is measured by a light-microscope technique in which membrane material with a known surface area is extracted into a long, thin cylindrical strand. The radius of the strand is calculated from its known length and surface area. The minimum radius, obtained at high extraction velocities or large membrane tensions, is 55 angstroms. A collapsed membrane cylinder with a mean-mass radius of 55 angstroms would have a membrane thickness of 78 angstroms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hochmuth, R M -- Evans, C A -- Wiles, H C -- McCown, J T -- HL 23728/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 1;220(4592):101-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828875" target="_blank"〉PubMed〈/a〉

    Description: Efforts in estimating carcinogenic risk in humans from long-term exposure to chemical carcinogens have centered on the problem of low-dose extrapolation. For chemicals with metabolites that interact with DNA, it may be more meaningful to relate tumor response to the concentration of the DNA adducts in the target organ rather than to the applied dose. Many data suggest that the relation between tumor response and concentration of DNA adducts in the target organ may be linear. This implies that the nonlinearities of the dose-response curve for tumor induction may be due to the kinetic processes involved in the formation of carcinogen metabolite--DNA adducts. Of particular importance is the possibility that the kinetic processes may show a nonlinear "hockey-stick" like behavior which results from saturation of detoxification or DNA repair processes. The mathematical models typically used for low-dose extrapolation are shown potentially to overestimate risk by several orders of magnitude when nonlinear kinetics are present.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoel, D G -- Kaplan, N L -- Anderson, M W -- New York, N.Y. -- Science. 1983 Mar 4;219(4588):1032-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6823565" target="_blank"〉PubMed〈/a〉

    Description: Technological hazards are evaluated in terms of quantitatively expressed physical, biological, and social descriptors. For each hazard a profile is constructed that considerably extends the conventional definition of risk. The profile, which is termed hazardousness, was understood in pilot experiments on perception and appeared to capture a large fraction of lay people's concern with hazard. It also suggests an orderly method for establishing priorities for the management of hazards.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hohenemser, C -- Kates, R W -- Slovic, P -- New York, N.Y. -- Science. 1983 Apr 22;220(4595):378-84.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836279" target="_blank"〉PubMed〈/a〉

    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〉

As expected, the antifibrin activity was inhibited by the peptide antigen but not by a control heptapeptide. In a chicken ex vivo circulatory model for fibrin detection, intravenously administered monoclonal antibodies bound to human fibrin-coated disks placed in an extracorporeal chamber.

    Description: Our concept of intelligence has been heavily influenced by the development of intelligence tests as screening devices in education and personnel selection. An alternative approach is to begin with a theory of the process of cognition and identify those aspects of individual mental performance that should be important on theoretical grounds. Three classes of performance have been identified. These deal with a person's choice of an internal representation for a problem, strategies for manipulating the representation, and abilities to execute elementary information processing steps required by the strategy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunt, E -- New York, N.Y. -- Science. 1983 Jan 14;219(4581):141-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6849125" target="_blank"〉PubMed〈/a〉

Analysis of the serum extracts showed that the substance which released immunoreactive estradiol after hydrolysis has chromatographic properties identical to those of fatty acid esters of estradiol esterified at carbon 17. The physiological role of these previously unknown endogenous esters might be inferred from their structural similarity to synthetic drugs used therapeutically for their prolonged estrogenic action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janocko, L -- Hochberg, R B -- CA29591/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Dec 23;222(4630):1334-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6419346" target="_blank"〉PubMed〈/a〉

    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: Glutathione, a tripeptide thiol found in virtually all cells, functions in metabolism, transport, and cellular protection. It participates in the reduction of disulfides and other molecules, and conjugates with compounds of exogenous and endogenous origin. It protects cells against the destructive effects of reactive oxygen intermediates and free radicals. Modifications of glutathione metabolism may be achieved by administration of selective enzyme inhibitors, and also by giving compounds that increase glutathione synthesis. Such effects are useful in chemotherapy and radiation therapy and in protecting cells against the toxic effects of drugs, other foreign compounds, and oxygen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meister, A -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):472-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836290" target="_blank"〉PubMed〈/a〉

    Description: Concentrations of biogenic amine metabolites in discrete brain areas differed significantly between dogs with genetically transmitted narcolepsy and age- and breed-matched controls. Dopamine and 3,4-dihydroxyphenylacetic acid were consistently elevated in the brains of narcoleptic animals, while homovanillic acid was not. Narcoleptic animals consistently exhibited lower utilization of dopamine and higher intraneuronal degradation of dopamine but no uniform decrease in serotonin utilization. Hence neuropathology appears to be associated with genetically transmitted canine narcolepsy. The data indicate a nonglobal depression of dopamine utilization or turnover or both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mefford, I N -- Baker, T L -- Boehme, R -- Foutz, A S -- Ciaranello, R D -- Barchas, J D -- Dement, W C -- MH 05804/MH/NIMH NIH HHS/ -- MH 23861/MH/NIMH NIH HHS/ -- NS 13211/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 May 6;220(4597):629-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6188216" target="_blank"〉PubMed〈/a〉

    Description: Glucose given to the newborn human may result in hyperglycemia, suggesting that its utilization is impaired at this developmental stage. Galactose is thought to be a more appropriate carbohydrate source for the newborn. The enzymes involved in hexose phosphorylation may, in part, be responsible for these observations. A key regulatory enzyme of hepatic glucose assimilation, glucokinase, is diminished in newborns compared to adults, whereas galactokinase activity is increased. When newborn dogs were fasted and then fed either glucose or galactose, their plasma insulin responses to glucose were similar, but the pups fed galactose demonstrated an attenuated systemic appearance rate of glucose. Hexose incorporation into hepatic glycogen and net glycogen synthesis was augmented in the galactose-fed dogs. In vitro, liver from neonatal dogs showed enhanced galactokinase activity relative to that for hexokinase or glucokinase. Neonatal hexose assimilation may be independent of insulin action and, instead, be related to the developmental presence of hexose phosphorylating enzymes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kliegman, R M -- Miettinen, E L -- Morton, S -- HD05740/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):302-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836273" target="_blank"〉PubMed〈/a〉

    Description: The epithelium of nasal tissue excised from subjects with cystic fibrosis exhibited higher voltage and lower conductance than tissue from control subjects. Basal sodium ion absorption by cystic fibrosis and normal nasal epithelia equaled the short-circuit current and was amiloride-sensitive. Amiloride induced chloride ion secretion in normal but not cystic fibrosis tissue and consequently was more effective in inhibiting the short-circuit current in cystic fibrosis epithelia. Chloride ion-free solution induced a smaller hyperpolarization of cystic fibrosis tissue. The increased voltage and amiloride efficacy in cystic fibrosis reflect absorption of sodium ions across an epithelium that is relatively impermeable to chloride ions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knowles, M R -- Stutts, M J -- Spock, A -- Fischer, N -- Gatzy, J T -- Boucher, R C -- HL00787/HL/NHLBI NIH HHS/ -- HL16674/HL/NHLBI NIH HHS/ -- HL22624/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 9;221(4615):1067-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308769" target="_blank"〉PubMed〈/a〉

    Description: Human beings have been manipulating the genetic characteristics plants and animals since the introduction of agriculture indirect manipulation of human genes occurred with widespread use of public health and medical measures that preserve genes causing disease. The production of biologicals by DNA technology raises few ethical problems. Predictive medicine in which genetic markers (including DNA variants) are used for antenatal and preclinical diagnosis of genetic diseases and susceptibilities poses new questions of confidentiality, private versus societal goals, and self-determination. When normal DNA is used to treat the somatic cells of patients with hemoglobinopathies and other genetic diseases, no new ethical problems arise beyond those presented by an novel theory. In contrast, manipulation of DNA in human fertilized eggs would constitute a qualitative departure from previous therapies since this would affect future generations. In order to be able to make wise decisions on these matters the public must be well informed. Thus, formal and informal education in human biology and genetics must be improved at all levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Motulsky, A G -- New York, N.Y. -- Science. 1983 Jan 14;219(4581):135-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6336852" target="_blank"〉PubMed〈/a〉

    Description: A substitution of alanine for valine at position 126 in the beta-chain of hemoglobin was discovered in a hematologically normal adult male of Lebanese extraction. The variant beta-globin was initially observed and subsequently purified by reverse-phase high-performance liquid chromatography (HPLC). Reverse-phase HPLC was also used to isolate the variant tryptic peptide of beta-T13 that has alanine replacing valine at residue 126. The discovery of hemoglobin Beirut illustrates the usefulness of reverse-phase HPLC for the detection of neutral amino acid substitutions in proteins. The ability to detect neutral substitutions in undigested proteins is pertinent to the monitoring of genetic variation in human populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strahler, J R -- Rosenbloom, B B -- Hanash, S M -- R01-HL25541/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Aug 26;221(4613):860-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6879181" target="_blank"〉PubMed〈/a〉

    Description: By means of visual stimnulus without temporal or spatial edges, we have achieved better isolation of chromatic signals at detection threshold than has been reported previously.

    Description: Endothelial cells from human blood vessels were cultured in vitro, with doubling times of 17 to 21 hours for 42 to 79 population doublings. Cloned human endothelial cell strains were established for the first time and had similar proliferative capacities. This vigorous cell growth was achieved by addition of heparin to culture medium containing reduced concentrations of endothelial cell growth factor. The routine cloning and long-term culture of human endothelial cells will facilitate studying the human endothelium in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thornton, S C -- Mueller, S N -- Levine, E M -- AG-00839/AG/NIA NIH HHS/ -- T32-CA-09171/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Nov 11;222(4624):623-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6635659" target="_blank"〉PubMed〈/a〉

    Description: The distribution of T cells and T cell subsets was examined within the human central nervous system in active lesions from seven patients with chronic multiple sclerosis. The monoclonal antibodies anti-T11, anti-T4, and anti-T8 were used to detect total (whole) T cells, helper T cells, and suppressor-cytotoxic T cells, respectively, and a monoclonal antibody against human Ia was used for macrophages and B cells. Lesion progression was associated with large numbers of T4+ cells at the lesion margin and these extended great distances into the adjacent normal-appearing white matter. T8+ cells were most commonly concentrated around the lesion margin and displayed a preferential perivascular distribution. Within the lesion center, only a few T cells were found. Ia+ macrophages were most numerous within the centers of active lesions and were always present in the adjacent normal white matter. The monoclonal antibodies to T cells did not cross-react with glial cells including oligodendrocytes. These results indicate that T4+ cells are actively involved in lesion extension and Ia+ cells, in demyelination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Traugott, U -- Reinherz, E L -- Raine, C S -- New York, N.Y. -- Science. 1983 Jan 21;219(4582):308-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6217550" target="_blank"〉PubMed〈/a〉

    Description: Bone morphogenetic protein and bone-derived growth factors are biochemical tools for research on induced cell differentiation and local mechanisms controlling cell proliferation. Bone morphogenetic protein irreversibly induces differentiation of perivascular mesenchymal-type cells into osteoprogenitor cells. Bone-derived growth factors are secreted by and for osteoprogenitor cells and stimulate DNA synthesis. Bone generation and regeneration are attributable to the co-efficiency of bone morphogenetic protein and bone-derived growth factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Urist, M R -- DeLange, R J -- Finerman, G A -- DEO2103-17/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1983 May 13;220(4598):680-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6403986" target="_blank"〉PubMed〈/a〉

    Description: Three new reagents that react against human T cells were synthesized by covalently linking the toxin ricin to monoclonal antibodies recognizing differentiation antigens on the surface of T lymphocytes. Each of these immunotoxins selectively inhibited T-cell proliferation when the cells were incubated in the presence of lactose. Multipotent human stem cells were inhibited only at much higher concentrations. Mixtures of all three immunotoxins were more effective than any one alone. These reagents have the potential for preventing graft-versus-host disease in man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vallera, D A -- Ash, R C -- Zanjani, E D -- Kersey, J H -- LeBien, T W -- Beverley, P C -- Neville, D M Jr -- Youle, R J -- CA-25097/CA/NCI NIH HHS/ -- CA-31618/CA/NCI NIH HHS/ -- CA-31685/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Nov 4;222(4623):512-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6353579" target="_blank"〉PubMed〈/a〉

    Description: The incidence of lymphocytes resistant to the purine analog 6-thioguanine was studied in seven patients with Bloom's syndrome. The mean frequency was 17.3 X 10(-4). The mean incidence in age- and sex-matched controls was 2.1 X 10(-4), so approximately eight times the normal number of 6-thioguanine-resistant lymphocytes were detected in Bloom's syndrome blood. The basis for this increase is unknown, but the inherent genomic instability demonstrated in the form of chromosomal aberrations is one possible explanation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vijayalaxmi -- Evans, H J -- Ray, J H -- German, J -- HD 0413/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1983 Aug 26;221(4613):851-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6879180" target="_blank"〉PubMed〈/a〉

    Description: Faced with limited resources, the United States must set priorities for research to identify preventable causes of cancer. A quantitative approach to priority setting, based on principles of decision analysis and cost-effectiveness analysis, can offer guidance in this process. An illustrative application of such a model suggests that the National Institutes of Health-supported clinical trial of dietary beta-carotene offers a greater expected reduction in cancer mortality per research dollar than carcinogen bioassays of high-volume industrial chemicals such as p-dichlorobenzene. National research priorities should reflect the relative cost-effectiveness of such investments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, M C -- New York, N.Y. -- Science. 1983 Jul 1;221(4605):17-23.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6407110" target="_blank"〉PubMed〈/a〉

    Description: A protoplast fusion method was developed to stably transfect human cells with pSV2-derived plasmids at frequencies greater than 10(-3). This procedure made it possible to test the biological effect of a hepatitis B virus (HBV) gene independent of the viral structures required for infection. A pSV2gpt+ plasmid constructed to carry a subgenomic fragment of HBV that contained the core antigen gene (HBc gene) was transfected into human cells. A human epithelial cell line was stably transfected with the HBc+ gene by selecting recipient cells for expression of guanine phosphoribosyl transferase expression. With this gpt+/HBc+ cell line it was shown that growth in serum-free medium or treatment with 5'-azacytidine stimulates the production of the HBV core antigen. A hepatocellular carcinoma carrying the entire HBV genome was stimulated to produce the HBc gene product in response to the same factors that stimulated HBcAg production in the gpt+/HBc+ cell line constructed by transfection. The temporal relation between the cytopathologic response and HBc gene expression was similar for both cell types, indicating a primary role for HBc gene expression in the cytopathology of HBV-infected human liver.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoakum, G H -- Korba, B E -- Lechner, J F -- Tokiwa, T -- Gazdar, A F -- Seeley, T -- Siegel, M -- Leeman, L -- Autrup, H -- Harris, C C -- New York, N.Y. -- Science. 1983 Oct 28;222(4622):385-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6194563" target="_blank"〉PubMed〈/a〉

Antibodies directed against the lipid were seen in serums from leprosy patients but not in serums from uninfected controls or patients infected with other mycobacteria, including Mycobacterium tuberculosis. The antibody response distinguished between the Mycobacterium leprae lipid and the structurally related phenolic glycolipid from Mycobacterium kansasii.

    Description: High-resolution banding techniques for the study of human chromosomes have revealed that the malignant cells of most tumors analyzed have characteristic chromosomal defects. Translocations of the same chromosome segments with precise breakpoints occur in many leukemias and lymphomas, and a specific chromosome band is deleted in several carcinomas. Trisomy, or the occurrence of a particular chromosome in triplicate, is the only abnormality observed in a few neoplasias. It is proposed that chromosomal rearrangements play a central role in human neoplasia and may exert their effects through related genomic mechanisms. Thus, a translocation could serve to place an oncogene next to an activating DNA sequence, a deletion to eliminate an oncogene repressor, and trisomy to carry extra gene dosage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yunis, J J -- CA31024/CA/NCI NIH HHS/ -- CA33314/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 15;221(4607):227-36.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6336310" target="_blank"〉PubMed〈/a〉

    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〉

    Description: The delta 15N values of bone collagen from Eskimos and from Northwest Coast Indians dependent on salmon fishing are about 10 per mil more positive than those from agriculturalists in historic times. Among prehistoric humans, two groups dependent on marine food sources show bone collagen delta 15N values that are 4 to 6 per mil more positive than those from two agricultural groups. The nitrogen isotope ratios of bone collagen from prehistoric inhabitants of the Bahamas are anomalously low for reasons that relate to the biogeochemical cycle of nitrogen in coral reefs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoeninger, M J -- DeNiro, M J -- Tauber, H -- New York, N.Y. -- Science. 1983 Jun 24;220(4604):1381-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6344217" target="_blank"〉PubMed〈/a〉

    Description: The compound 2-phenylethylamine is an "endogenous amphetamine" which may modulate central adrenergic functions. 2-Phenylethylamine is mainly metabolized by monoamine oxidase to form phenyl acetate (PAA). The 24-hour urinary excretion of PAA was measured in normal healthy volunteers and depressed patients. Patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, edition 3. In 70 percent of healthy volunteers of both sexes, the excretion of PAA ranged between 70 and 175 milligrams per 24 hours (mean = 141.1 +/- 10.2). Inpatients with major depressive disorder (unipolar type) (N = 31) excreted less PAA (68.7 +/- 7.0 milligrams per 24 hours) and 55 percent of them excreted less than 70 milligrams per 24 hours; there were no significant differences in the PAA excretion between untreated patients (N = 13) and those treated with antidepressants that were not effective (N = 18). The PAA excretion was reduced to a lesser extent in 35 less severely depressed unipolar outpatients (drug-free for 1 week) (86.3 +/- 11.8 milligrams per 24 hours). These results suggest that low PAA urinary excretion may be a reliable state marker for the diagnosis of some forms of unipolar major depressive disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sabelli, H C -- Fawcett, J -- Gusovsky, F -- Javaid, J -- Edwards, J -- Jeffriess, H -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1187-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857245" target="_blank"〉PubMed〈/a〉

    Description: The structure of the messenger RNA (mRNA) encoding the precursor to mouse submaxillary epidermal growth factor (EGF) was determined from the sequence of a set of overlapping complementary DNA's (cDNA). The mRNA is unexpectedly large, about 4750 nucleotide bases, and predicts the sequence of preproEGF, a protein of 1217 amino acids (133,000 molecular weight). The EGF moiety (53 amino acids) is flanked by polypeptide segments of 976 and 188 amino acids at its amino and carboyxl termini, respectively. The amino terminal segment of the precursor contains seven peptides with sequences that are similar but not identical to EGF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scott, J -- Urdea, M -- Quiroga, M -- Sanchez-Pescador, R -- Fong, N -- Selby, M -- Rutter, W J -- Bell, G I -- 21344/PHS HHS/ -- New York, N.Y. -- Science. 1983 Jul 15;221(4607):236-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6602382" target="_blank"〉PubMed〈/a〉

    Description: Angiographically demonstrable coronary artery spasm could be provoked repeatedly by giving intracoronary or intravenous injections of histamine to miniature swine with experimentally induced atherosclerotic lesions of the coronary artery. The spasm induced in this way subsided either spontaneously or after the administration of nitroglycerin and was prevented by a calcium antagonist or an agent that blocks histamine H1 receptors. This model, which suggests that atherosclerotic changes may be one of the primary factors in the occurrence of coronary artery spasm, should facilitate studies on the pathogenesis of this condition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shimokawa, H -- Tomoike, H -- Nabeyama, S -- Yamamoto, H -- Araki, H -- Nakamura, M -- Ishii, Y -- Tanaka, K -- New York, N.Y. -- Science. 1983 Aug 5;221(4610):560-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6408736" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Although official efforts to control air pollution have traditionally focused on outdoor air, it is now apparent that elevated contaminant concentrations are common inside some private and public buildings. Concerns about potential public health problems due to indoor air pollution are based on evidence that urban residents typically spend more than 90 percent of their time indoors, concentrations of some contaminants are higher indoors than outdoors, and for some pollutants personal exposures are not characterized adequately by outdoor measurements. Among the more important indoor contaminants associated with health or irritation effects are passive tobacco smoke, radon decay products, carbon monoxide, nitrogen dioxide, formaldehyde, asbestos fibers, microorganisms, and aeroallergens. Efforts to assess health risks associated with indoor air pollution are limited by insufficient information about the number of people exposed, the pattern and severity of exposures, and the health consequences of exposures. An overall strategy should be developed to investigate indoor exposures, health effects, control options, and public policy alternatives.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spengler, J D -- Sexton, K -- ES-01108/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 1;221(4605):9-17.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857273" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Flow cytometry revealed that, in the presence of tritiated thymidine, a greater percentage of phytohemagglutinin-stimulated lymphocytes from old human donors were arrested in the G2 or M phase than were cells from young donors. Furthermore, lymphocytes from old donors showed significantly more chromosomal damage than did lymphocytes from young donors. Lymphocyte cultures from old or young donors not exposed to tritiated thymidine had the same percentage of cycling lymphocytes in G2 or M, although the number of lymphocytes stimulated by phytohemagglutinin to enter the cell cycle was significantly lower in cultures from old donors. Thus, the impaired incorporation of tritiated thymidine by phytohemagglutinin-exposed lymphocytes from old humans reflects both an impaired proliferative response to phytohemagglutinin and an increased sensitivity to the radiobiological effects of tritiated thymidine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Staiano-Coico, L -- Darzynkiewicz, Z -- Hefton, J M -- Dutkowski, R -- Darlington, G J -- Weksler, M E -- New York, N.Y. -- Science. 1983 Mar 18;219(4590):1335-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828861" target="_blank"〉PubMed〈/a〉

    Description: Dissimilarities in perception elicited by stimulation with two electrodes were estimated. A two-dimensional spatial configuration was found to be suitable to represent the dissimilarity data, and the two dimensions could be interpreted as corresponding to the position of the apical and basal electrode of the two-electrode combination. A speech-processing strategy that converts acoustic, first and second formants to two-electrode stimulation is proposed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tong, Y C -- Dowell, R C -- Blamey, P J -- Clark, G M -- New York, N.Y. -- Science. 1983 Feb 25;219(4587):993-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6823564" target="_blank"〉PubMed〈/a〉

    Description: Schizophrenic patients with high ventricle brain ratios and cortical brain atrophy, as shown by computerized tomography, had decreased spinal fluid concentrations of homovanillic acid and dopamine-beta-hydroxylase activity. These decreased cerebral spinal fluid concentrations in patients with brain atrophy support the proposal of disturbed noradrenaline and dopamine neurotransmission in a subgroup of schizophrenic patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Kammen, D P -- Mann, L S -- Sternberg, D E -- Scheinin, M -- Ninan, P T -- Marder, S R -- van Kammen, W B -- Rieder, R O -- Linnoila, M -- New York, N.Y. -- Science. 1983 May 27;220(4600):974-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6133351" target="_blank"〉PubMed〈/a〉

    Description: Histopathologic examination of lymph nodes from 39 patients with clinical and pathological criteria for cat scratch disease revealed delicate pleomorphic Gram-negative bacilli in 34 of the 39 nodes. They were within the walls of capillaries in or near areas of follicular hyperplasia and within microabscesses. They were best seen with the Warthin-Starry silver impregnation stain. Organisms in lymph node sections exposed to convalescent serum from three patients and to immunoperoxidase stained equally well with all three samples. The organisms did not react with hyperimmune sera to Legionella pneumophila nor to several species of Rickettsia. These bacilli appear to be the causative agents of cat scratch disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wear, D J -- Margileth, A M -- Hadfield, T L -- Fischer, G W -- Schlagel, C J -- King, F M -- New York, N.Y. -- Science. 1983 Sep 30;221(4618):1403-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6612349" target="_blank"〉PubMed〈/a〉

    Description: In citrate agar electrophoresis hemoglobin appears to bind reversibly to the sulfated polysaccharide agaropectin, a natural component of Difco Bacto-Agar. This complex migrates anodally, since the hemoglobin is only weakly positively charged at pH 6.2 whereas the carbohydrate carries a net negative charge. Electroendosmosis, on the other hand, proceeds in the cathodal direction. These opposing fluxes separate the hemoglobins in the order of their affinity for agaropectin. An agaropectin binding site was identified on hemoglobin by computer-assisted modeling, and the relation of the site to hemoglobin variants that exhibit abnormal citrate agar mobility was established. The citrate anion is postulated to function as a "counter ion." Preliminary evidence indicates that agaropectin has antigelling properties with respect to hemoglobin S.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winter, W P -- Yodh, J -- HL-15160/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 8;221(4606):175-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6190229" target="_blank"〉PubMed〈/a〉
