    Description: Scheduling theory is used to extend the additive factors method of analyzing reaction times to tasks involving concurrent processing. Data indicate that mental processes in a double-stimulation experiment by Becker are executed in a critical-path network. A relationship predicted for the timing of the responses of the task is shown to hold.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schweickert, R -- New York, N.Y. -- Science. 1980 Aug 8;209(4457):704-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7394529" target="_blank"〉PubMed〈/a〉

    Description: The ability to see spatial structures of a wide range of sizes was measured for two groups of observers (mean ages, 18 and 73 years). All observers had good visual acuity. Although older and younger observers did not differ in ability to see targets with fine structure (high spatial frequencies), older observers were only one-third as sensitive to targets with coarse structure (low spatial frequencies) as were younger observers or to changes in criterion. Older observers were also less able than younger observers to see moving targets. The reduced sensitivity of the older observers may adversely affect routine perceptual activities, such as face recognition and visually guided postural behavior, that depend upon low spatial frequencies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sekuler, R -- Hutman, L P -- Owsley, C J -- New York, N.Y. -- Science. 1980 Sep 12;209(4462):1255-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403884" target="_blank"〉PubMed〈/a〉

    Description: A strain of type 2 human rotavirus (Wa) was grown to relatively high titer through 14 passages in primary cultures of African green monkey kidney (AGMK) cells. This passage series was initiated with virus that had been passaged 11 times serially in newborn gnotobiotic piglets. In contrast, virus present in the stool of patient Wa as well as virus from the first, second, or third passage in piglets could not be propagated successfully in African green monkey kidney cells. Prior to each passage in cell culture, the virus was treated with trypsin and the inoculated cultures were centrifuged at low speed. Cultivation of a type 2 human rotavirus should aid attempts to characterize this virus and to develop a means of immunoprophylaxis for a serious diarrheal disease of human infants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wyatt, R G -- James, W D -- Bohl, E H -- Theil, K W -- Saif, L J -- Kalica, A R -- Greenberg, H B -- Kapikian, A Z -- Chanock, R M -- New York, N.Y. -- Science. 1980 Jan 11;207(4427):189-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6243190" target="_blank"〉PubMed〈/a〉

    Description: Sexual dimorphism in selected extragenital tissues is described with emphasis on the molecular basis of the differences. Testosterone rather than 5 alpha-dihydrotestosterone appears to be the major intracellular androgen in organs other than skin and reproductive tract, but other steroid metabolites and their receptors are required to produce the diverse tissue differences observed in males and females. There is also evidence that multiple hormones from several endocrine glands are required to act in concert with androgens to produce and maintain their effects. Although many of the consequences of sexual dimorphism, such as body size and strength, have been evident for centuries, other differences between males and females such as disease incidence, response to drugs and toxins, and the metabolism and assimilation of dietary constituents have only recently been discovered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bardin, C W -- Catterall, J F -- HD-13541/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 20;211(4488):1285-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010603" target="_blank"〉PubMed〈/a〉

    Description: The basic realities of the distribution of the world's population, wealth, and agricultural production base are not conducive to an automatic stabilizing process for the world's hungry. Increasing volatility in the world grain production in the 1980's could create a problem of major proportions. By 1990, the developed world will account for 24 percent of the world's population, 85 percent of the world's economic activity, and around 50 percent of the world's grain production and consumption. On a per capita basis, the developed world will consume nearly three times as much grain as the developing countries which account for three-fourths of the world's population. Increased food aid, which is essential, is not the solution to the basic problem. The low-income countries need a massive infusion of capital investment, research support, and education if they are to build infrastructures that have the capacity to produce, distribute, and market food supplies. Other options serve only to prolong and aggravate the current disparities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barr, T N -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1087-95.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7302579" target="_blank"〉PubMed〈/a〉

    Description: Throughout development, Mongolian gerbils engage in conspicuous naso-oral investigations of their social partners' mouth areas. The behavioral contribution of saliva-related stimuli in regulating oral-directed responses was studied during several important phases of the gerbil's social life. Weanlings were preferentially attracted to their mother's saliva, subadults at puberty preferred saliva of littermates to that of nonlittermates, and sexually experienced males preferred the saliva of estrous females to that of nonestrous females. The use of saliva as a discriminative cue during various developmental periods suggests that oral chemostimuli have a perennial role in regulating social interchanges.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Block, M L -- Volpe, L C -- Hayes, M J -- R03MH 27346/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 6;211(4486):1062-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466378" target="_blank"〉PubMed〈/a〉

    Description: Intense rapid eye movements (REM) during sleep were investigated as a possible indication of delay in the neurodevelopment of infants. The rate of occurrence of REM storms was determined by monitoring the sleep of 15 normal, first-born infants during weeks 2 through 5 and at 3, 6, 12 months. The amount of REM within each 10-second interval of active sleep was rated on a four-point scale based on frequency and intensity of eye movements. When the babies were 12 months old, the Bayley Scales of Mental Development were administered. A significant negative correlation was found between the frequency of REM storms of 14 subjects was also studied. The negative correlation was confirmed. The findings support the suggestion that by 6 months of age REM storms express dysfunction or delay in the development of central inhibitory feedback controls for sleep organization and phasic sleep-related activities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Becker, P T -- Thoman, E B -- HD-12948/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 19;212(4501):1415-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233232" target="_blank"〉PubMed〈/a〉

    Description: In a replicated experiment, nonbreeding winter populations of Microtus montanus were given supplements of rolled oats coated with 6-methoxybenzoxazolinone, a naturally occurring plant derivative. After 3 weeks of this feeding regime, samples from the populations demonstrated a high incidence of pregnancy in females and testicular hypertrophy in males. Control populations receiving rolled oats coated only with the solvent showed no reproductive activity. These results demonstrate that the presence of 6-methoxybenzoxazolinone in the plant food resource acts as the ultimate cue to trigger reproductive effort in Microtus montanus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berger, P J -- Negus, N C -- Sanders, E H -- Gardner, P D -- RR-07092/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 2;214(4516):69-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7025210" target="_blank"〉PubMed〈/a〉

    Description: Two maternally derived chromosome sets and both maternal histocompatibility antigen haplotypes were identified in the tissues of a malformed triploid acardiac twin that developed within the same chorion as its normal twin.

    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: The mutation component, M, is a measure of the proportion of the impact of a genetic condition that is attributable to recurrent mutation. For a trait maintained by balance between mutation and directional selection, M is approximately the broad-sense heritability; for a measured character where the mean and optimum coincide, M is about half the heritability. If the narrow-sense heritability is high, the impact changes relatively rapidly with a change in mutation rate. If the narrow-sense heritability is low, M cannot be predicted, but the change in impact following a change in mutation rate, if any, is very slow.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crow, J F -- Denniston, C -- New York, N.Y. -- Science. 1981 May 22;212(4497):888-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233180" target="_blank"〉PubMed〈/a〉

But sometimes the surviving similarities are so vague that even computer-based sequence comparisons procedures are unable to validate relationships.

    Description: A new technique has been developed for identifying, in humans, dynamic spatiotemporal electrical patterns of the brain during purposive behaviors. In this method, single-trial time-series correlations between brain macropotentials recorded from different scalp sites are analyzed by distribution-independent mathematical pattern recognition. Dynamic patterns of correlation clearly distinguished two brief visuomotor tasks differing only in type of mental judgement required (spatial or numeric). These complex patterns shifted in the anterior-posterior and left-right axes between successive 175-millisecond intervals, indicating that many areas in both cerebral hemispheres were involved even in these simple judgements. These patterns were not obtainable by conventional analysis of averaged evoked potentials or by linear analysis of correlations, suggesting that the new technique will advance the study of human brain activity related to cognition and goal-directed behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gevins, A S -- Doyle, J C -- Cutillo, B A -- Schaffer, R E -- Tannehill, R S -- Ghannam, J H -- Gilcrease, V A -- Yeager, C L -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):918-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256287" target="_blank"〉PubMed〈/a〉

    Description: Long-term implants releasing a small quantity of melatonin (45 nanograms per day) were used to determine the brain sites of the hormone's antigonadal action in a photoperiodic species, the white-footed mouse (Peromyscus leucopus). Implants in the medial preoptic and supra- and retrochiasmatic areas elicited completed gonadal regression after 7 weeks. Implants in other brain regions had little effect on the animals' reproductive state.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glass, J D -- Lynch, G R -- NS-15503/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 13;214(4522):821-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7292016" target="_blank"〉PubMed〈/a〉

    Description: Squirrel monkeys pressed a level at high rates under a second-order schedule of reinforcement in which level pressing produced a brief visual stimulus that was occasionally contiguous with an intravenous injection of nicotine. The rate of lever pressing could be markedly reduced either by substituting saline for nicotine injections or by blocking the effects of nicotine with mecamylamine. The rate of level pressing could be reduced by eliminating the brief visual stimulus. These results show that nicotine can function as an effective reinforcer under a second-order schedule of drug self-administration and that an environmental stimulus associated with nicotine intake can contribute to the maintenance of persistent drug-seeking behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldberg, S R -- Spealman, R D -- Goldberg, D M -- DA00499/DA/NIDA NIH HHS/ -- DA02658/DA/NIDA NIH HHS/ -- MH07658/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):573-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291998" target="_blank"〉PubMed〈/a〉

    Description: The effects of long- and short-term administration of the tricyclic antidepressant desipramine on intracranial self-stimulation in rats were studied with electrodes in the A10 region of the dopamine-containing cell bodies of the ventromedial tegmentum. Long-term desipramine administration resulted in a significant shift to the left in the ascending portion of the rate--current intensity function, indicating that the activity of the mesolimbic dopamine system was enhanced. These findings point to a possible dopaminergic mechanism of action of antidepressants and support speculations concerning the role of dopamine-containing neurons in the pathophysiology of depression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fibiger, H C -- Phillips, A G -- New York, N.Y. -- Science. 1981 Nov 6;214(4521):683-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7197394" target="_blank"〉PubMed〈/a〉

    Description: Subjects with type III hyperlipoproteinemia develop premature atherosclerosis and have hyperlipidemia due to an increase in cholesterol-rich very low density lipoproteins (VLDL) of abnormal electrophoretic mobility. Apolipoprotein E is a major protein constituent of VLDL and appears to be important for the hepatic uptake of triglyceride-rich lipoproteins. A new kindred of patients with type III hyperlipoproteinemia is described in which no plasma apolipoprotein E could be detected, consistent with the concept that type III hyperlipoproteinemia may be due to an absence or striking deficiency of apolipoprotein E.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghiselli, G -- Schaefer, E J -- Gascon, P -- Breser, H B Jr -- New York, N.Y. -- Science. 1981 Dec 11;214(4526):1239-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6795720" target="_blank"〉PubMed〈/a〉

    Description: Human malignant cancer tumors grafted into nude mice produce tumors containing both human cancer cells and the host's stromal cells. After short-term propagation of these tumors in vitro, the murine mesenchymal cells appear transformed and are tumorigenic in nude mice. However, established human cancer cell lines fail to similarly after adjacent murine stromal cells when used to produce tumors in nude mice. These experiments suggest that cancer cells may recruit normal cells to become malignant, qualifying the view of the clonal (unicellular) origin of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldenberg, D M -- Pavia, R A -- 1R01 CA17198/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209521" target="_blank"〉PubMed〈/a〉

    Description: Natural killer cells are a recently discovered subpopulation of lymphoid cells that are present in most normal individuals of a range of mammalian and avian species. Natural killer cells have spontaneous cytolytic activity against a variety of tumor cells and some normal cells, and their reactivity can be rapidly augmented by interferon. They have characteristics distinct from other types of lymphoid cells and are closely associated with large granular lymphocytes, which comprise about 5 percent of blood or splenic leukocytes. There is increasing evidence that natural killer cells, with the ability to mediate natural resistance against tumors in vivo, certain virus and other microbial diseases, and bone marrow transplants, may play an important role in immune surveillance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herberman, R B -- Ortaldo, J R -- New York, N.Y. -- Science. 1981 Oct 2;214(4516):24-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7025208" 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〉

    Description: The perception of emotion in verbal and facial expression, and the spontaneous production of conversational speech were studied in patients with unilateral focal excisions of frontal, temporal, or parieto-occipital cortex. Lesions of the left hemisphere impaired the matching of verbal descriptions to appropriate verbal categories of emotional states, whereas with lesions of the right hemisphere, the matching of different faces displaying similar emotional states was impaired. The effects of lesions of both left and right hemisphere occurred regardless of the locus of the lesion. On the other hand, frontal-lobe lesions had differential effects upon unsolicited talking; lesions of the left frontal lobe virtually abolished this behavior, whereas lesions of the right frontal lobe produced excessive talking. These data suggest that the nature of the behavioral stimulus as well as the locus and side of damage must be considered in the study of the neural basis of affective behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kolb, B -- Taylor, L -- New York, N.Y. -- Science. 1981 Oct 2;214(4516):89-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280683" target="_blank"〉PubMed〈/a〉

    Description: Human keratinocytes, derived from the skin of newborns and of adults, were grown in the complete absence of serum, in a hormone-supplemented medium on fibronectin-coated cell culture dishes at low seed density. The cell culture medium consisted of Medium 199 containing epidermal growth factor, triiodothyronine, hydrocortisone, Cohn fraction IV, insulin, transferrin, bovine brain extract, and trace elements. Removal of the brain extract from the hormone supplement had a greater negative impact on proliferation of the keratinocyte cultures than did the removal of epidermal growth factor, hydrocortisone, and triiodothyronine or Cohn fraction IV. The growth of keratinocytes in this hormone-supplemented medium suggests that control of keratinocyte growth depends in large part on endocrine stimulation by other body organs, including the brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maciag, T -- Nemore, R E -- Weinstein, R -- Gilchrest, B A -- AG 0599/AG/NIA NIH HHS/ -- HO 07374/HO/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 27;211(4489):1452-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6970413" target="_blank"〉PubMed〈/a〉

    Description: Ten patients with multiple sclerosis who were treated with human fibroblast interferon (IFN-B) for 6 months showed a significant reduction in their exacerbation rates compared with their rates before treatment (P 〈 .01). The IFN-B was administered intrathecally by serial lumbar punctures. There was no significant change in the exacerbation rates of ten multiple sclerosis control patients before and during the period of observation. The IFN-B recipients have now been on the study a mean of 1.5 years, the controls, 1.2 years. The clinical condition of five of the IFN-B recipients and one of the control patients has improved, whereas the condition of five of the controls and one of the IFN-B recipients has deteriorated (P 〈 .036). These findings warrant cautious optimism about the efficacy of intrathecal IFN-B in altering the course of multiple sclerosis and support concepts of a viral or dysimmune etiology of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobs, L -- O'Malley, J -- Freeman, A -- Ekes, R -- CA-18533/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 27;214(4524):1026-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6171035" target="_blank"〉PubMed〈/a〉

    Description: Data from the New York Cancer Registry show no evidence for higher cancer rates associated with residence near the Love Canal toxic waste burial site in comparison with the entire state outside of New York City. Rates of liver cancer, lymphoma, and leukemia, which were selected for special attention, were not consistently elevated. Among the other cancers studied, a higher rate was noted only for respiratory cancer, but it was not consistent across age groups and appeared to be related to a high rate for the entire city of Niagara Falls. There was no evidence that the lung cancer rate was associated with the toxic wastes buried at the dump site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janerich, D T -- Burnett, W S -- Feck, G -- Hoff, M -- Nasca, P -- Polednak, A P -- Greenwald, P -- Vianna, N -- New York, N.Y. -- Science. 1981 Jun 19;212(4501):1404-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233229" target="_blank"〉PubMed〈/a〉

    Description: Total concentrations of estrogen receptor in the uterine nuclear fraction are reduced rapidly after progesterone treatment of the proestrous hamster. Progesterone acts selectively on the occupied form of the nuclear estrogen receptor, with no effect on the concentration of an unoccupied form. This observation indicates that progesterone modulates the action of estrogen by controlling nuclear retention of the estrogen-receptor complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okulicz, W C -- Evans, R W -- Leavitt, W W -- New York, N.Y. -- Science. 1981 Sep 25;213(4515):1503-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280669" target="_blank"〉PubMed〈/a〉

    Description: A substance related to luteinizing hormone-releasing hormone was demonstrated, by immunohistochemical procedures, in the cytoplasm of interstitial cells within the rat testes. In many seminiferous tubules, nuclei of spermatogonial cells were also immunopositive. Both cytoplasmic and nuclear fractions of testicular homogenates contain immunoreactive compounds, and this report identifies which cell types contain this substance. The localization of a peptide hormone within the nucleus of a target cell population may indicate its mode of action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paull, W K -- Turkelson, C M -- Thomas, C R -- Arimura, A -- HD14761/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 11;213(4513):1263-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7022653" target="_blank"〉PubMed〈/a〉

    Description: Mice fed a purified diet low in copper display anemia, hypoceruloplasminemia, depressed concentrations of liver copper, and elevated concentrations of liver iron. An impaired humoral-mediated immune response (decreased numbers of antibody-producing cells) is observed in mice with severe as well as marginal copper deficiency. The magnitude of this impairment is highly correlated with the degree of functional copper deficiency (hypoceruloplasminemia).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prohaska, J R -- Lukasewycz, O A -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):559-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244654" target="_blank"〉PubMed〈/a〉

    Description: Raji cells, a human B lymphoblastoid cell line of Burkitt lymphoma origin, formed lupus inclusions when grown in a medium conditioned by the growth of Raji cells whose DNA thymidine residues had been unifilarly (single-strandedly) substituted with bromodeoxyuridine. Ultracentrifugation of this medium in excess of that required to remove Epstein-Barr virus and all other known mammalian viruses did not prevent the formation of the inclusions, and treatment of the conditioned medium with pronase destroyed the activity. These results demonstrate the presence of a protein that is secreted from bromodeoxyuridine-substituted Raji cells and is capable of inducing nonbromodeoxyuridine-substituted cells to form lupus inclusions. Interferon (100 units per milliliter) was found in the conditioned medium. Inclusions also formed in Raji cells grown in fresh medium supplemented with human leukocyte or fibroblast interferon (100 units per milliliter).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rich, S A -- New York, N.Y. -- Science. 1981 Aug 14;213(4509):772-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6166984" target="_blank"〉PubMed〈/a〉

    Description: During the rod-isolated phase of dark adaption, b-wave implicit time of the human cone electroretinogram increased exponentially with a time constant corresponding to that for the regeneration of rhodopsin. In the presence of different photopically equated short-wave backgrounds, cone b-wave implicit time varied inversely with the scotopic brightness of the background. Taking into account the origin of the b wave, these measurements support the idea of a rod effect on cone function in the distal human retina.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sandberg, M A -- Berson, E L -- Effron, M -- EY00169/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1981 May 15;212(4496):829-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221568" target="_blank"〉PubMed〈/a〉

    Description: The insertion of oxygenated sterol compounds into human red blood cell membranes as well as the consequent transformation of the red cells to an echinocyte shape and the expansion of the membranes are impeded by the presence of serum lipoproteins in the incubation medium. All density classes of human serum lipoproteins bind oxygenated sterol compounds, and lipoproteins can act as acceptors of oxygenated sterols previously inserted into red cells. Since oxygenated sterols have been reported to be atherogenic, the modulating and possibly protective effects of serum lipoproteins on oxygenated sterol-induced derangement of cell membrane structure and function may provide a useful model for further study.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Streuli, R A -- Chung, J -- Scanu, A M -- Yachnin, S -- 1 P30 AM26678-01/AM/NIADDK NIH HHS/ -- HL 18577/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 12;212(4500):1294-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233221" target="_blank"〉PubMed〈/a〉

    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. The results suggest a specific receptor-ligand interaction between endothelial cells and a component, components, in the knobs of the infected erythrocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Udeinya, I J -- Schmidt, J A -- Aikawa, M -- Miller, L H -- Green, I -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):555-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7017935" target="_blank"〉PubMed〈/a〉

    Description: Women have made tremendous strides in educational attainment in science and engineering over the past decade, increasing their proportion of doctorate awards in these fields from 7 percent in 1965 to 23 percent in 1980. But they still have higher unemployment rates and lower salaries than men in all fields of science and engineering, at all degree levels, and at all levels of experience; and the disparities between men and women widen with higher degree levels and with years of experience. Graduate enrollments indicate continuing increases over at least the next several years in degree awards to women, but their access to equal employment and advancement opportunities is not assured.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vetter, B M -- New York, N.Y. -- Science. 1981 Dec 18;214(4527):1313-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7313688" target="_blank"〉PubMed〈/a〉

    Description: The psychological principles that govern the perception of decision problems and the evaluation of probabilities and outcomes produce predictable shifts of preference when the same problem is framed in different ways. Reversals of preference are demonstrated in choices regarding monetary outcomes, both hypothetical and real, and in questions pertaining to the loss of human lives. The effects of frames on preferences are compared to the effects of perspectives on perceptual appearance. The dependence of preferences on the formulation of decision problems is a significant concern for the theory of rational choice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tversky, A -- Kahneman, D -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):453-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455683" target="_blank"〉PubMed〈/a〉

    Description: Normal male subjects attempted to deceive an experimenter recording electrodermal, respiratory, an cardiovascular activity. Those who had ingested a placebo or nothing were detected with statistically significant frequency on the basis of their phasic electrodermal responses, which clearly distinguished them from truthful suspects. That was not the case with deceptive subjects who had ingested 400 milligrams of meprobamate, nor did the examiner detect which subjects had received the drug.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Waid, W M -- Orne, E C -- Cook, M R -- Orne, M T -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):71-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209522" target="_blank"〉PubMed〈/a〉

    Description: Vitellogenin is synthesized under estrogen control in the liver, extensively modified, transported to the ovary, and there processed to the yolk proteins lipovitellin and phosvitin. In the frog Xenopus laevis there are at least four distinct but related vitellogenin genes. The two genes A1 and A2 have a 95 percent sequence homology in their messenger RNA coding regions, and contain 33 introns that interrupt the coding region (exons) at homologous positions. Sequences and lengths of analogous introns differ, and many introns contain repetitive DNA elements. The introns in these two genes that have apparently arisen by duplication have diverged extensively by events that include deletions, insertions, and probably duplications. Rapid evolutionary change involving rearrangements and the presence of repeated DNA suggests that the bulk of the sequences within introns may not have any specific function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wahli, W -- Dawid, I B -- Ryffel, G U -- Weber, R -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):298-304.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209528" target="_blank"〉PubMed〈/a〉

    Description: Aversive classical conditioning of Aplysia californica, a gastropod mollusk suited for neurobiological study, produces a learned reaction to the chemosensory conditioned stimulus that is expressed as a marked facilitation of four defensive responses: two graded reflexes (head and siphon withdrawal), an all-or-none fixed act (inking), and a complex fixed action pattern (escape locomotion). In addition, the conditioned stimulus produces a concomitant depression of at least one appetitive response, feeding. These extensive and selective actions of the conditioned stimulus in Aplysia resemble the actions of conditioned fear stimuli in higher mammals and suggest that the functional equivalent of fear occurs in invertebrates and thus may be an adaptive mechanism that is widespread in the animal kingdom.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walters, E T -- Carew, T J -- Kandel, E R -- 5K02MH0081/MH/NIMH NIH HHS/ -- 5K05MH18558/MH/NIMH NIH HHS/ -- 5T32MH1574/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):504-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7192881" target="_blank"〉PubMed〈/a〉

    Description: Per capita cigarette consumption has declined annually since 1973. This downturn represents a new nonsmoking ethos, which is also reflected in the legislative successes of the nonsmokers' rights movement. Time series regression analysis of cigarette demand suggests that, in the absence of the antismoking campaign, consumption would have exceeded its 1978 level by more than a third.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warner, K E -- HS 03634/HS/AHRQ HHS/ -- New York, N.Y. -- Science. 1981 Feb 13;211(4483):729-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455711" target="_blank"〉PubMed〈/a〉

    Description: Arginine vasopressin and a number of its synthetic analogs augment memory functions in experimental animals. One of these analogs, 1-desamino-8-D-arginine vasopressin (DDAVP), influences human learning and memory. Cognitively unimpaired, as well as cognitively impaired adults, treated with DDAVP for a period of several days, learn information more effectively, as measured by the completeness, organization, and consistency (reliability) of recall. DDAVP also appears to reverse partially the retrograde amnesia that follows electroconvulsive treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weingartner, H -- Gold, P -- Ballenger, J C -- Smallberg, S A -- Summers, R -- Rubinow, D R -- Post, R M -- Goodwin, F K -- New York, N.Y. -- Science. 1981 Feb 6;211(4482):601-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455701" target="_blank"〉PubMed〈/a〉
