    Description: In recent decades, age-adjusted mortality rates from prostatic cancer have risen precipitously among blacks, remaining unchanged among whites. It is now the most common cancer among United States black males. When nonwhite mortality rates were examined by age and birth cohort, it was found that peak rates occurred at every age in the cohort of 1896 to 1900, and declined thereafter. This presages an arrest and reversal of the time trend in summary mortality rates as more recent nonwhite cohorts reach the ages of maximum risk.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ernster, V L -- Selvin, S -- Winkelstein, W Jr -- New York, N.Y. -- Science. 1978 Jun 9;200(4346):1165-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/653361" target="_blank"〉PubMed〈/a〉

    Description: A sustained-release device for use in ethanol dependence studies in mice is described. The Silastic device, dubbed SERT (sustained ethanol release tube), holds 0.35 milliliter of 95 percent ethanol (by volume) and is implanted under the skin of the back where it releases ethanol for up to 12 hours, with no observable tissue damage. The device may be adaptable to the release of other volatile liquids or drugs, in other animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Erickson, C K -- Koch, K I -- Mehta, C S -- McGinity, J W -- New York, N.Y. -- Science. 1978 Mar 31;199(4336):1457-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/564551" target="_blank"〉PubMed〈/a〉

    Description: The city of Warsaw was razed at the end of World War II and rebuilt under a socialist government whose policy was to allocate dwellings, schools, and health facilities without regard to social class. Of the 14,238 children born in 1963 and living in Warsaw, 96 percent were given the Raven's Progressive Matrices Test and an arithmetic and a vocabulary test in March to June of 1974. Information was collected on the families of the children, and on characteristics of schools and city districts. Parental occupation and education were used to form a family factor, and the district data were collapsed into two factors, one relating to social marginality, and the other to distance from city center. Analysis showed that the initial assumption of even distribution of family, school, and district attributes was reasonable. Mental performance was unrelated either to school or district factors; it was related to parental occupation and education in a strong and regular gradient. It is concluded that an egalitarian social policy executed over a generation failed to override the association of social and family factors with cognitive development that is characteristic of more traditional industrial societies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Firkowska, A N -- Ostrowska, A -- Sokolowska, M -- Stein, Z -- Susser, M -- Wald, I -- New York, N.Y. -- Science. 1978 Jun 23;200(4348):1357-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663616" target="_blank"〉PubMed〈/a〉

    Description: Evaluation of the efficacy of a medical intervention requires valid measurements of both its benefits and risks as compared to those of alternative forms of management. The requisite measurements are more difficult to make than this simple description suggests, and the accumulation of information is further inhibited by certain characteristics of our pattern of health care. These features include, for example, discontinuous care by a variety of unrelated providers, inadequate records, the autonomy of physicians as decision-makers, financial disincentives, ambiguities in what we mean by "experimental" and "accepted" forms of therapy, and failure to see continuing evaluation as a necessary component of the cost of providing good medical care. Although no single change will solve all the problems of evaluation, several offer promise of improving our ability to choose from among medical interventions those most likely to be useful.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frazier, H S -- Hiatt, H H -- New York, N.Y. -- Science. 1978 May 26;200(4344):875-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/417402" target="_blank"〉PubMed〈/a〉

    Description: Individual hypothalamic nuclei were microdissected from brain tissue of ten human subjects who had died suddenly while in apparent good health. Appreciable amounts of vasopressin and oxytocin immunoreactivity were found by specific radioimmunoassay in six hypothalamic nuclei including supraoptic and paraventricular nuclei. Vasopressin and oxytocin are presumed to be synthesized in supraoptic and paraventricular nuclei for axonal transport to the posterior pituitary for storage and release. Vasopressin and oxytocin in other hypothalamic nuclei may be a part of this system of neurosecretion or may serve some other function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉George, J M -- New York, N.Y. -- Science. 1978 Apr 21;200(4339):342-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/556308" target="_blank"〉PubMed〈/a〉

    Description: Deoxygenation of concentrated solutions (0.33 gram per milliliter) of sickle cell hemoglobin show (i) a "crisis point" where the oxygen binding curve is unusually steep (Hill coefficient of 5 to 6), and (ii) a simultaneous increase in light scattering. Nearly identical oxygen binding curves are obtained upon oxygenation and deoxygenation of these solutions. The influence of aggregation is to shift the curve toward higher pressures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gill, S J -- Skold, R -- Fall, L -- Shaeffer, T -- Spokane, P -- Wyman, J -- New York, N.Y. -- Science. 1978 Jul 28;201(4353):362-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663663" target="_blank"〉PubMed〈/a〉

    Description: Electron microscope autoradiographs were prepared of IM-9 human cultured lymphocytes incubated with iodine-125-labeled insulin. With the use of [125I]insulin and Ilford L-4 emulsion, the technique had a resolution half-distance of approximately 0.085 micrometer. Autoradiographs revealed a time-dependent entry of insulin into the cell interior that was maximal after 30 minutes of incubation. At this time point nearly 40 percent of the [125I]insulin was in the interior of the cell at a distance 1 micrometer or greater from the plasma membrane. Grain distribution and volume density analyses revealed that the intracellular insulin was concentrated in the endoplasmic reticulum and nuclear membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldfine, I D -- Jones, A L -- Hradek, G T -- Wong, K Y -- Mooney, J S -- New York, N.Y. -- Science. 1978 Nov 17;202(4369):760-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/715440" target="_blank"〉PubMed〈/a〉

    Description: Cultured skin fibroblasts from subjects with clinically apparent diabetes mellitus and from subjects genetically predisposed to diabetes have a replicative lifespan that is inversely related to donor age. Fibroblasts from carefully defined normal subjects not predisposed to diabetes fail to show this correlation.

    Description: Explants of human chorion-decidual tissue obtained at delivery from normal, full-term pregnancies synthesize and secrete prolactin. This hormone is indistinguishable from pituitary prolactin by chromatographic, electrophoretic, immunologic, and receptor assay techniques.

    Description: This experiment examined the effects on memory of various amnestic treatments in animals earlier treated with the alpha-adrenergic antagonist phenoxybenzamine (PBZ). Thirty minutes before being trained in a one-trial inhibitory (passive) avoidance task, animals received an injection of PBZ or saline. Immediately after training, each animal received one of the following amnestic treatments: stimulation of the frontal cortex or amygdala, pentylenetetrazol, diethyldithiocarbamate, or cycloheximide. In control animals, each treatment produced retrograde amnesia. However, PBZ-treated animals did not develop amnesia. These findings suggest that there may be a common neurobiological mechanism underlying the amnesias produced by many treatments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gold, P E -- Sternberg, D B -- New York, N.Y. -- Science. 1978 Jul 28;201(4353):367-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/208153" target="_blank"〉PubMed〈/a〉

    Description: In cultures made from disaggregated human epidermal cells, growth to a confluent cell layer is followed by the emergence of patterns resembling those of human dermatoglyphs. These patterns reflect intrinsic properties of kertinocytes. In vivo, only the epidermis of the volar surfaces forms patterns, but in culture, patterns are formed by epidermal cells from other sites as well. Patterns develop by a process of cell movement which first produces ridges and then curves the ridges into figures of increasing complexity, ultimately whorls.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, H -- Thomas, J -- New York, N.Y. -- Science. 1978 Jun 23;200(4348):1385-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663617" target="_blank"〉PubMed〈/a〉

The colors were chosen to be discriminable only by the cones, only by the rods, or both.

    Description: Enkephalin-like activity has been measured in the ventricular cerebrospinal fluid of patients with intractable pain. Electrical stimulation of periventricular brain sites resulted in significant decrease in persistent pain in these subjects. This analgesia, which was blocked by naloxone in 80% of the cases, was accompanied by a significant rise in ventricular enkephalin-like activity, as measured by two different methods. The results present evidence of in vivo release of enkephalin-like material in humans and suggest that stimulation analgesia may be partially due to this release.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akil, H -- Richardson, D E -- Hughes, J -- Barchas, J D -- New York, N.Y. -- Science. 1978 Aug 4;201(4354):463-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663668" target="_blank"〉PubMed〈/a〉

    Description: Multitubular enzyme reactors with immobilized phenylalanine ammonia lyase were tested in vitro and in vivo for depletion of phenylalanine in circulating blood. Sustained reduction of phenylalanine was achieved in less than 30 minutes. A 50% decrease of phenylalanine was obtained with a 2-hour application of enzyme reactors and was maintained for more than 2 days. Similar enzyme reactors have therapeutic potential for temporary management of phenylketonuric patients when their circulating phenylalanine becomes exceedingly high because of infection, fever, or pregnancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ambrus, C M -- Ambrus, J L -- Horvath, C -- Pedersen, H -- Sharma, S -- Kant, C -- Mirand, E -- Guthrie, R -- Paul, T -- New York, N.Y. -- Science. 1978 Sep 1;201(4358):837-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/567372" target="_blank"〉PubMed〈/a〉

    Description: Subjects who were either high or low in trait anxiety used alpha feedback to increase and to decrease their electroencephalographic alpha activity. The alpha changes were tightly linked to anxiety changes, but only in high anxiety subjects (for whom anxiety was reduced in proportion to alpha increases, and was increased in proportion to alpha suppression). Low trait-anxiety subjects were superior at both enhancement and suppression training, but their alpha changes were not related to anxiety changes. In both groups, anxiety changes were generally unrelated to either resting levels or changes in frontalis electromyograms and respiration rate. These results suggest that long-term alpha feedback training (at least 5 hours) may be useful in anxiety therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hardt, J V -- Kamiya, J -- New York, N.Y. -- Science. 1978 Jul 7;201(4350):79-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663641" target="_blank"〉PubMed〈/a〉

    Description: Cell-mediated and humoral immune responses against antigens associated with primate C-type oncoviruses were evaluated in humans by microcytotoxicity and radioimmunoprecipitation assays. Five of six women tested sequentially during pregnancy developed selective cell-mediated reactivity against baboon endogenous virus (BEV)--infected human fibroblasts. Responsiveness peaked during the second and third trimesters and corresponded temporally with elevated antibody levels to BEV antigens. Similar cell-mediated reactivity was not observed in nonpregnant individuals. Selective cell-mediated reactivity directed against cells infected with the simian sarcoma virus-simian sarcoma associated virus complex (SSV--SSAV) was observed in four of 20 healthy adults (three of 14 nonpregnant, one of six pregnant). These observations suggest that cell-mediated reactivity against primate C-type oncoviruses is occasionally detected in healthy nonpregnant adults, but that during pregnancy both cell-mediated and humoral reactivity against BEV may become selectively expressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirsch, M S -- Kelly, A P -- Chapin, D S -- Fuller, T C -- Black, P H -- Kurth, R -- New York, N.Y. -- Science. 1978 Mar 24;199(4335):1337-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/204010" target="_blank"〉PubMed〈/a〉

This factor also inhibits the enzyme collagenase derived from cultured human skin and collagenase extracted from human granulocytes.

    Description: Human populations native to areas of intense sunlight tend to be heavily melanized. Previous explanations for this relationship have invoked only weak selective pressures. To test the hypothesis that dark pigmentation may protect against photolysis of crucial light-sensitive vitamins and metabolites by ultraviolet light, folate was used as a model. It was found that exposure of human plasma in vitro to simulated strong sunlight causes 30 to 50 percent loss of folate within 60 minutes. Furthermore, light-skinned patients exposed to ultraviolet light for dermatologic disorders have abnormally low serum folate concentrations, suggesting that photolysis may also occur in vivo. Deficiency of folate, which occurs in many marginally nourished populations, causes severe anemia, fetal wastage, frank infertility, and maternal mortality. Prevention of ultraviolet photolysis of folate and other light sensitive nutrients by dark skin may be sufficient explanation for the maintenance of this characteristic in human groups indigenous to regions of intense solar radiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Branda, R F -- Eaton, J W -- New York, N.Y. -- Science. 1978 Aug 18;201(4356):625-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/675247" target="_blank"〉PubMed〈/a〉

    Description: The human brain is found to produce a magnetic field near the scalp which varies in synchrony with periodic electrical stimulation applied to a finger. Use of a highly sensitive superconducting quantum interference device as a magnetic field detector reveals that the brain's field is sharply localized over the primary projection area of the sensory cortex contralateral to the digit being stimulated. The phase of the response at the stimulus frequency varies monotonically with the repetition rate and at intermediate frequencies yields a latency of approximately 70 milliseconds for cortical response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brenner, D -- Lipton, J -- Kaufman, L -- Williamson, S J -- New York, N.Y. -- Science. 1978 Jan 6;199(4324):81-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, New York University, New York, NY 10003, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17569490" target="_blank"〉PubMed〈/a〉

    Description: Mortality and morbidity from infectious diseases in the United States have declined more than 90 percent since 1900. Factors believed to be responsible for this decline include changes in the natural history of disease, sanitation, quarantine measures, control of nonhuman vectors, antibacterial drugs, and immunization. The contributions of each of these factors differ among the various infectious diseases; except for smallpox and diphtheria control, immunization had little effect until after World War II. The success of present and future immunization programs is endangered by public and physician complacency and by complex legal and ethical problems related to informed consent and responsibility for rare, vaccine-related injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mortimer, E A Jr -- New York, N.Y. -- Science. 1978 May 26;200(4344):902-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/347579" target="_blank"〉PubMed〈/a〉

    Description: The clonal proliferation of the committed granulocyte-macrophage stem cell is controlled by a balance between mutually opposing factors, colony stimulating factor and prostaglandin E, both of monocyte-macrophage derivation. Increases beyond a critical concentration of colony stimulating factor within the local milieu of the mononuclear phagocyte induces the coincident elaboration of prostaglandin E, a self-regulated response which serves to limit the unopposed humoral stimulation of myelopoiesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurland, J I -- Bockman, R S -- Broxmeyer, H E -- Moore, M A -- New York, N.Y. -- Science. 1978 Feb 3;199(4328):552-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/304600" target="_blank"〉PubMed〈/a〉

    Description: Peripheral administration of the COOH-terminal octapeptide of cholecystokinin in doses from 1 to 100 micrograms per kilogram of body weight (0.25 to 25.0 micrograms per rat) significantly antagonized tail pinch-induced eating in rats, an animal model for stress-induced human hyperphagia. Centrally administered cholecystokinin was effective only in high doses (3 micrograms into the cerebral ventricle). The finding that the minimal effective dose of cholecystokinin in suppressing stress-induced appetitive behavior is smaller after peripheral than central administration suggests that the peptide is acting on peripheral, as opposed to central nervous system, substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nemeroff, C B -- Osbahr, A J 3rd -- Bissette, G -- Jahnke, G -- Lipton, M A -- Prange, A J -- New York, N.Y. -- Science. 1978 May 19;200(4343):793-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/565535" target="_blank"〉PubMed〈/a〉

    Description: Three techniques have been used to measure human plasma melatonin: bioassay, radioimmunoassay, and gas chromatography--mass spectrometry (GC-MS). GC-MS is theoretically capable of the greatest specificity, but in general suffers from insufficient sensitivity. Negative chemical ionization, a new technique, provides a 150-fold increase in GC-MS sensitivity for electron-capturing compounds. Negative chemical ionization GC-MS permits routine measurement in human plasma of melatonin at a concentration as low as 1 picogram per milliliter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lewy, A J -- Markey, S P -- New York, N.Y. -- Science. 1978 Aug 25;201(4357):741-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/675255" target="_blank"〉PubMed〈/a〉

    Description: Immunoglobulin G, produced in cultures of splenic lymphocytes obtained from patients with Hodgkin's disease, bound to a population of homologous peripheral blood lymphocytes and initiated antibody-dependent cell cytotoxicity in cultures from five out of eight patients. Two patients whose cultures produced negative results had minimal disease; the other was in remission. The target cells appear to be T lymphocytes; the effector cells bear Fc receptors that are inhibited by antigen-antibody complexes. Antibody-dependent cell cytotoxicity events may produce the anergy and lymphopenia often seen in Hodgkin's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Longmire, R L -- Ryan, S -- McMillan, R -- Lightsey, A -- Heath, V -- New York, N.Y. -- Science. 1978 Jan 6;199(4324):71-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Hematology and Oncology, Scripps Clinic and Research Foundation, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17569485" target="_blank"〉PubMed〈/a〉

    Description: Erythroid colonies, raised from erythroid stem cells circulating in the peripheral blood of normal adult individuals, synthesize considerable amounts of fetal hemoglobin. In cultures from persons with sickling disorders, amounts of hemoglobin F that are known to inhibit sickling in vivo are produced. The results provide evidence that primitive erythroid progenitors are able to express the hemoglobin F production program and that cultures of mononuclear cells of the adult blood can be used to investigate the mechanisms involved in regulation of gamma-globin gene switching.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Papayannopoulou, T -- Nakamoto, B -- Buckley, J -- Kurachi, S -- Nute, P E -- Stamatoyannopoulos, G -- New York, N.Y. -- Science. 1978 Mar 24;199(4335):1349-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/628844" target="_blank"〉PubMed〈/a〉

    Description: Long-term treatment of rats with haloperidol produced an increased sensitivity to the locomotor and stereotypic effect of apomorphine. This behavioral dopaminergic supersensitivity was accompanied by increased binding of [3H] spiroperidol in the striatum. Rats treated concurrently with lithium and haloperidol failed to develop both behavioral sensitivity to apomorphine and increased striatal dopamine receptor binding. The ability of lighium to prevent recurrent manicdepressive episodes may be related, in part, to its ability to stabilize dopaminergic receptor sensitivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pert, A -- Rosenblatt, J E -- Sivit, C -- Pert, C B -- Bunney, W E Jr -- New York, N.Y. -- Science. 1978 Jul 14;201(4351):171-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/566468" target="_blank"〉PubMed〈/a〉

    Description: On 17 May 1954 the Supreme Court, in its decision in Brown v. Board of Education, declared de jure segregation of the public schools to be unconstitutional. It is argued here that a consequence of that decision was a decline in childbearing among white Southerners. In the nation as a whole, period fertility rates increased between 1954 and 1955, but in 9 of the 11 former Confederate states they decreased. Further analysis shows that these Southern fertility decreases began about 12 months after the Supreme Court decision. This variation in behavior in reaction to a historical event has important implications for the explanation and prediction of fertility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rindfuss, R R -- Reed, J S -- John, C -- New York, N.Y. -- Science. 1978 Jul 14;201(4351):178-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/351806" target="_blank"〉PubMed〈/a〉

    Description: The kinetics of sickling of malaria-infected red cells from humans with sickle cell trait were studied in vitro in an attempt to obtain direct experimental evidence for a selective advantage of the hemoglobin S heterozygote in a malarious region. The sickling rates of cells infected with Plasmodium falciparum and of non-infected cells were studied both in the total absence of oxygen (by dithionite addition) and at several different concentrations of oxyhemoglobin which might obtain in vivo. In all cases, red cells containing small plasmodium parasite forms (ring forms) sickled approximately eight times as readily as uninfected cells. Cells containing large parasitic forms (trophozoites and schizonts) appeared to sickle less readily than uninfected cells, by light microscopy criteria, but electron micrographs demonstrated the presence of polymerized deoxyhemoglobin S with a high frequency. It is concluded that enhanced sickling of plasmodium-infected AS cells may be one mechanism whereby the hemoglobin S polymorphism is balanced in favor of the heterozygote.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roth, E F Jr -- Friedman, M -- Ueda, Y -- Tellez, I -- Trager, W -- Nagel, R L -- New York, N.Y. -- Science. 1978 Nov 10;202(4368):650-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/360396" target="_blank"〉PubMed〈/a〉

    Description: Compared with children of school age, infants show ten times the incidence and considerably greater amounts of clinically significant astigmatism. The amount begins to decrease in the second semester of life, and the incidence declines during the third year. The unanticipated results bear on both the etiology and the neural sequelae of astigmatism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mohindra, I -- Held, R -- Gwiazda, J -- Brill, J -- New York, N.Y. -- Science. 1978 Oct 20;202(4365):329-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/694539" target="_blank"〉PubMed〈/a〉

    Description: This article proposes a modification of the currently accepted view of the central neural integration of body temperature. In place of a single integrator with multiple inputs and outputs, the new model includes as many integrators as there are thermoregulatory responses. Futhermore, these integrators are postulated to be represented at many levels of the nervous system, with each level facilitated or inhibited by levels above and below. The purpose of such a complicated arrangement is to achieve finer and finer control over body temperature. A consideration of how endothermy might have evolved, with originally nonthermally related responses gradually coming under thermal control, makes such a brain organization highly reasonable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Satinoff, E -- New York, N.Y. -- Science. 1978 Jul 7;201(4350):16-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/351802" target="_blank"〉PubMed〈/a〉

    Description: In otherwise profoundly akinetic rats that had been severely depleted of brain catecholamines, anticholinergic drugs caused excessive walking. The effect did not appear until 10 days after surgery and then increased with time, suggesting that a phenomenon analogous to denervation supersensitivity may be involved. If the animals walked into corners, they were unable to turn around or back out. Their gait (extremely short steps) was reminiscent of that of patients with Parkinson's disease. The results are consistent with a mutually antagonistic interaction between cholinergic and dopaminergic brain systems and emphasize certain complexities in this interaction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schallert, T -- Whishaw, I Q -- Ramirez, V D -- Teitelbaum, P -- New York, N.Y. -- Science. 1978 Mar 31;199(4336):1461-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/564552" target="_blank"〉PubMed〈/a〉

    Description: Tricyclic antidepressants vary in their capacity to cause psychomotor activation, to relieve agitated depressive states, and to cause sedation and hypotension. We have quantified relative potencies of tricyclic antidepressants in competing for the binding of 3H-labeled WB-4101 to alpha-noradrenergic receptor sites in rat brain membranes. Affinities of tricyclic drugs for alpha-noradrenergic receptor sites in the brain correlate well with the capacity of these agents to relieve psychomotor agitation and to induce sedation and hypotension; these affinities also correlate inversely with tendencies to elicit psychomotor activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉U'Prichard, D C -- Greenberg, D A -- Sheehan, P P -- Snyder, S H -- New York, N.Y. -- Science. 1978 Jan 13;199(4325):197-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/202024" target="_blank"〉PubMed〈/a〉

    Description: We used an assay in vitro to investigate the possible role of streptococcal adherence to human pharyngeal cells in the pathogenesis of acute rheumatic fever. There was no difference in adherence of rheumatic fever-associated and non-associated strains of group A streptococci to pooled pharyngeal cells of normal people. Likewise, streptococci not associated with rheumatic fever adhered equally well to cells taken from normal people and from patients with rheumatic heart disease. However, the pharyngeal cells of all nine rheumatic heart disease patients tested had increased avidity for adherence for a rheumatic fever-associated strain of streptococcus compared to the pharyngeal cells obtained from age- and sex-matched controls. Increased streptococcal adherence to pharyngeal cells of rheumatic fever-prone patients may play a role in the pathogenesis of rheumatic fever.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Selinger, D S -- Julie, N -- Reed, W P -- Williams, R C Jr -- New York, N.Y. -- Science. 1978 Aug 4;201(4354):455-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/351810" target="_blank"〉PubMed〈/a〉

    Description: The rapid expansion of knowledge in human and medical genetics has revealed at least 6 percent average heterozygosity per structural gene locus, in excess of 2300 Mendelian (single gene) variants and several hundred chromosomal variants in man. This means that with the exception of monozygous twins, no two individuals are alike in their phenotype. Therefore, each person has a relative state of health, and genetic factors contribute significantly to disease. The ubiquity of genetic diversity requires the development of services for genetic screening, diagnosis, and counseling to prevent and treat a major portion of disease in modern society. Specific programs in Quebec and Canada illustrate how individuals and populations can be served by such services. Better education of citizens and health professionals in human genetics is essential for the further improvement of genetics services in society.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scriver, C R -- Laberge, C -- Clow, C L -- Fraser, F C -- New York, N.Y. -- Science. 1978 May 26;200(4344):946-52.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/644337" target="_blank"〉PubMed〈/a〉

    Description: Rotaviruses cause gastroenteritis in man and a wide variety of animal species. They cross-react in many immunologic tests and have a similar appearance by electron microscopy, making differentiation among them difficult. Rotaviruses derived from different host species were distinguished by postinfection serum blocking virus activity in an enzyme-linked immunosorbent assay (ELISA). Thirty-three rotavirus isolates from children living in three different parts of the world could not be differentiated by this technique, but they were distinct from four strains recovered from calves, and a series of strains isolated from piglets, foals, monkeys, and infant mice. The four bovine strains were similar, but they could be differentiated from the other animal strains, each of which exhibited a distinct pattern when tested by the ELISA blocking technique.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yolken, R H -- Barbour, B -- Wyatt, R G -- Kalica, A R -- Kapikian, A Z -- Chanock, R M -- New York, N.Y. -- Science. 1978 Jul 21;201(4352):259-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/208150" target="_blank"〉PubMed〈/a〉

In each case the characteristic behavior of pimozide-treated rats was the same as that of undrugged rats when reward was simply withheld. Drug-induced performance difficulties were ruled out by the presence of periods of normal responding in drug-treated animals. Pimozide appears to selectively blunt the rewarding impact of food and other hedonic stimuli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wise, R A -- Spindler, J -- deWit, H -- Gerberg, G J -- New York, N.Y. -- Science. 1978 Jul 21;201(4352):262-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/566469" target="_blank"〉PubMed〈/a〉

    Description: Growth of the human breast cancer cell line MCF-7 is enhanced by androgens, but only at pharmacological concentrations. Although physiological concentrations of androgens translocate the androgen receptor into the nucleus, no mitogenic effects are observed. By contrast, pharmacological androgens translocate not only the androgen receptor but also the estrogen receptor, and at these high doses significantly increase both DNA and estrogen-dependent protein synthesis. We therefore propose that androgens stimulate MCF-7 cell growth not through the androgen receptor but rather through the estrogen receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zava, D T -- McGuire, W L -- New York, N.Y. -- Science. 1978 Feb 17;199(4330):787-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622569" target="_blank"〉PubMed〈/a〉

The paradox can be explained by the high cost of medical care, the overselling of medicine's capabilities, the expectation that the physician will be both ultrascientific and as emphathic as yesterday's doctor, and little recognition that the curing of one illness in the elderly exposes this group to other disease. Finally, though the physician is trained to manage illnesses, he is also given the excessively broad task of improving personal and societal practices disadvantageous to health.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ingelfinger, F J -- New York, N.Y. -- Science. 1978 May 26;200(4344):942-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/644336" target="_blank"〉PubMed〈/a〉

    Description: Injections of adrenocorticotropic hormone (ACTH) into the periaqueductal gray matter of drug-naive rats resulted in a dose-dependent opiate abstinence syndrome characterized by fearful hyperreactivity and explosive motor behavior. Injecting shorter chains of ACTH caused attenuated forms of this behavior. Injections of beta-endorphin at this same site caused opposite behavior: sedative, analgestic, and catatonic. If the effects of morphine are mediated by two classes of receptor) and the other which is not stereospecific and naloxone-insensitive--the endogtor)--and the other which is not stereospecific and naloxone-insensitive the endogenous ligand of the second receptor may be ACTH. The neuropeptides ACTH and endorphin may be part of an integrated neuromodulatory system, and the opiate abstinence syndrome may be the result of an altered interaction between the two receptor systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacquet, Y F -- New York, N.Y. -- Science. 1978 Sep 15;201(4360):1032-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/210506" target="_blank"〉PubMed〈/a〉

    Description: Covalent light chain dimers (L2) and cysteine-blocked L chain monomers readily react with partially reduced heavy (H) chains. A rapid disappearance of these blocked L chain species is followed by the appearance of covalent intermediates-HL, H2, and H2L-leading to fully assembled H2L2. The mechanism of initial disulfide bond formation between heavy and light chains is disulfide interchange.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kazin, A R -- Beychok, S -- New York, N.Y. -- Science. 1978 Feb 10;199(4329):688-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/415360" target="_blank"〉PubMed〈/a〉

    Description: A well-known solution of the diffusion equation gives an exponential square-root function as the frequency response for a one-dimensional diffusion or transmission process. When two or more such processes are cascaded, the result is still an exponential square-root characteristic, but with a longer time constant. This seems to explain why flicker thresholds obey the Kelly-Veringa diffusion model at high frequencies, even though the psychophysically inferred diffusion process is much slower than the first stage of visual transduction measured by, for example, late receptor potentials. Two such stages in tandem are sufficient to account for the psychophysical data, because the psychophysical time constant is proportional to the square of the number of stages involved. In addition, the nonlinear behavior of flicker thresholds under intense light adaptation can be explained if the loss factor in the first stage is proportional to the amount of the photopigment bleached. Apparently the flicker thresholds are governed by first- and second-order retinal neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, D H -- Wilson, H R -- New York, N.Y. -- Science. 1978 Nov 24;202(4370):896-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/715449" target="_blank"〉PubMed〈/a〉

    Description: 3-Methoxy-4-hydroxyphenylglycol (MHPG) was measured in lumbar spinal fluid of 20 subjects with hypertension of varied etiology and severity. There was a significant correlation between the concentration of MHPG and the severity of hypertension. However, changes in the concentration of vanillylmandelic acid in the urine of these subjects were insignificant. In six subjects, administration of clonidine or alpha-methyldopa, two centrally acting antihypertensive drugs, was associated with a significant lowering of MHPG concentrations. These data support the hypothesis that central catecholamines are involved in clinical hypertension.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saran, R K -- Sahuja, R C -- Gupta, N N -- Hasan, M -- Bhargava, K P -- Shanker, K -- Kishor, K -- New York, N.Y. -- Science. 1978 Apr 21;200(4339):317-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/635588" target="_blank"〉PubMed〈/a〉

    Description: A new bioassay for chemical attractants of aquatic snails demonstrated that Biomphalaria glabrata could be attracted to or trapped in the vicinity of homogenates of lettuce. Fractionation of homogenates revealed the amino acids glutamate and proline and the primary attractants. Attraction was specific for the L form of glutamate. Proline appeared to stimulate reproductive activity. Glutathione, gamma-aminobutyric acid, and a number of other compounds had no effect. Extracts of lyophilized snail tissue also attracted other snails and may thus contain pheromones. These results permit formulation and testing of controlled-release attractants designed to overcome the repellant effects of slow-release molluscicides, as well as the design of stimulants to be used with no-release poisons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Uhazy, L S -- Tanaka, R D -- MacInnis, A J -- New York, N.Y. -- Science. 1978 Sep 8;201(4359):924-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/684418" target="_blank"〉PubMed〈/a〉

    Description: Computers are used to influence diagnostic and therapeutic decisions. The computer's information-handling capabilities allow it to serve as a reliable extension of the physician's memory and expander of the physician's information and synthesized knowledge resources. Computers have been used to facilitate decisions through organization of patient data, improved classification of patients, decision analysis in clinical settings, and simulation of expert clinical reasoning. Computer programs are more successful in narrow, constrained, single arenas of medicine with much underlying pathophysiologic understanding and where decisions are based largely on hard laboratory data. New models of synthetic reasoning that simulate expert clinical behavior show promise of supporting complicated decisions concerning problems of multiple diseases. All systems are confronted by problems of consensus and authority of the underlying information used.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoolman, H M -- Bernstein, L M -- New York, N.Y. -- Science. 1978 May 26;200(4344):926-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/347580" target="_blank"〉PubMed〈/a〉
