    Description: Neurons in deep laminae of the rabbit cingulate cortex develop discriminative activity at an early stage of behavioral discrimination learning, whereas neurons in the anteroventral nucleus of thalamus and neurons in the superficial cortical laminae develop such activity in a late stage of behavioral learning. It is hypothesized that early-forming discriminative neuronal activity, relayed to anteroventral neurons via the corticothalamic pathway, contributes to the construction of changes underlying the late-forming neuronal discrimination in the anteroventral nucleus. The resultant late discriminative activity in the anteroventral nucleus is then relayed via the thalamocortical pathway back to the superficial cortical laminae, promoting disengagement of cortex from further task-processing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabriel, M -- Foster, K -- Orona, E -- New York, N.Y. -- Science. 1980 May 30;208(4447):1050-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375917" target="_blank"〉PubMed〈/a〉

    Description: Cytochemical staining of demyelinated peripheral axons revealed two types of axon membrane organization, one of which suggests that the demyelinated axolemma acquires a high density of sodium channels. Ferric ion-ferrocyanide stain was confined to a restricted region of axon membrane at the beginning of a demyelinated segment or was distributed throughout the demyelinated segment of axon. The latter pattern represents one possible morphological correlate of continuous conduction through a demyelinated segment and suggests a reorganization of the axolemma after demyelination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Foster, R E -- Whalen, C C -- Waxman, S G -- NS-15320/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 7;210(4470):661-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6159685" target="_blank"〉PubMed〈/a〉

    Description: In BALB/c female mice with melanoma transplants, the incidence of "takes" is decreased and survival is increased by hydroquinone, a melanocytolytic agent. The mechanism of drug action is suggested by via DNA. The significant and high degree of positive response to hydroquinone treatment in vivo is encouraging for the clinical management of melanoma with melanocytolytic agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chavin, W -- Jelonek, E J Jr -- Reed, A H -- Binder, L R -- New York, N.Y. -- Science. 1980 Apr 25;208(4442):408-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7367868" target="_blank"〉PubMed〈/a〉

    Description: Amnesic patients acquired a mirror-reading skill at a rate equivalent to that of matched control subjects and retained it for at least 3 months. The results indicate that the class of preserved learning skills in amnesia is broader than previously reported. Amnesia seems to spare information that is based on rules or procedures, as contrasted with information that is data-based or declarative--"knowing how rather than "knowing that." The results support the hypothesis that such a distinction is honored by the nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cohen, N J -- Squire, L R -- 1P50 MH 30914/MH/NIMH NIH HHS/ -- MH24600/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 10;210(4466):207-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7414331" target="_blank"〉PubMed〈/a〉

    Description: A spontaneous B cell leukemia (BCL1) grew progressively in normal BALB/c mice after injection of tumor cells but did not grow in splenectomized recipients. Despite the absence of progressive tumor growth, residual tumor cells with malignant potential were found in the peripheral blood of the splenectomized animals. Splenectomy performed after injection of tumor cells but before the development of marked leukocytosis also prevented progressive tumor growth and death of the host. Thus the spleen appears to be necessary for progressive proliferation of this lymphocytic leukemia early after passage in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kotzin, B L -- Strober, S -- New York, N.Y. -- Science. 1980 Apr 4;208(4439):59-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6965803" target="_blank"〉PubMed〈/a〉

    Description: The clinical laboratory is examined as a microcosm of the entire health care delivery system. The introduction of computers into the clinical laboratory raises issues that are difficult to resolve by the methods of information science or medical science applied in isolation. The melding of these two disciplines, together with the contributions of other disciplines, has created a new field of study called medical information science. The emergence of this new discipline and some specific problem-solving approaches used in its application in the clinical laboratory are examined.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lincoln, T L -- Korpman, R A -- New York, N.Y. -- Science. 1980 Oct 17;210(4467):257-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6999622" target="_blank"〉PubMed〈/a〉

    Description: Contrast thresholds for sine-wave gratings of spatial frequencies of 2, 4, 12, and 16 cycles per degree were determined for normal and disabled readers at a range of stimulus durations. Normal readers demonstrated monotonically decreasing sensitivity with increasing spatial frequency at exposure durations between 40 and 100 milliseconds. At exposure durations of 150 to 1000 milliseconds, they showed peak sensitivity at 4 cycles per degree. In comparison, disabled readers showed monotonically decreasing sensitivity with increasing spatial frequency at all stimulus durations. The difference in sensitivity pattern across spatial frequencies was greatest at stimulus durations approximately equal to fixation durations during reading.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lovegrove, W J -- Bowling, A -- Badcock, D -- Blackwood, M -- New York, N.Y. -- Science. 1980 Oct;210(4468):439-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7433985" target="_blank"〉PubMed〈/a〉

    Description: Mebendazole was highly effective against the helminth parasite Trichinella spiralis in mice subjected to a 3-day course of treatment during the invasive and encystment phases of experimental trichinellosis. When treatment began either 2 or 4 weeks after the mice were inoculated with parasites, the number of larvae developing in the host musculature was greatly reduced by twice-daily oral administration of 3.125, 6.25, or 12.5 milligrams of mebendazole per kilogram of body weight.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCracken, R O -- Taylor, D D -- New York, N.Y. -- Science. 1980 Mar 14;207(4436):1220-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355285" target="_blank"〉PubMed〈/a〉

    Description: Eating very little in the presence of food or failure to serach for food has been documented in various species during the hibernation season, incubation, molting, and defense of the territory or harem. At these times feeding competes with other, more important activities. One way to avoid conflicts between feeding and these other activities to lower the programmed weight or set-point for body fat. Experiments on mammalian hibernators and incubating birds provide evidence that set-points are indeed lowered. Failure to eat in these two examples depends on anorexia, loss of appetite. A review of other examples suggests that conceptualization in terms of lowered set-points provides a unified and testable way of understanding many naturally occurring instances of fasting in the animal kingdom. Finally, spontaneous animal anorexias are contrasted with attempts by people to lose weight.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mrosovsky, N -- Sherry, D F -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):837-42.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6928327" target="_blank"〉PubMed〈/a〉

    Description: The effects of a vitamin D deficiency on insulin and glucagon release was determined in the isolated perfused rat pancreas by radioimmunoassay of the secreted proteins. During a 30-minute period of perfusion with glucose and arginine, pancreases from vitamin D-deficient rats exhibited a 48 percent reduction in insulin secretion compared to that for pancreases from vitamin D-deficient rats that had been replenished with vitamin D. Vitamin D status had no effect on pancreatic glucagon secretion. This result, along with the previously demonstrated presence in the pancreas of a vitamin D-dependent calcium-binding protein and cytosol receptor for the hormonal form of vitamin D, 1,25-dihydroxyvitamin D3, indicates an important role for vitamin D in the endocrine functioning of the pancreas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Norman, A W -- Frankel, J B -- Heldt, A M -- Grodsky, G M -- New York, N.Y. -- Science. 1980 Aug 15;209(4458):823-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6250216" target="_blank"〉PubMed〈/a〉

    Description: Noradrenergic neurons in the hypothalamus involved in feeding and satiety are activated by gastrointestinal receptors. In the unrestrained rat, sites were first identified at which norepinephrine injected in the medial hypothalamus caused spontaneous feeding, or in the lateral hypothalamus caused no response. The activity of in vivo norepinephrine at these two sites was characterized by localized push-pull perfusion. When a nutrient was infused directly into the rat's duodenum, the synaptic release of hypothalamic norepinephrine was enhanced at lateral sites insensitive to norepinephrine, but suppressed at medial sites reactive to norepinephrine. Thus, signals from duodenal receptors are conceivably sent to the rat's brain to end feeding by way of noradrenergic inhibitory neurons in the hypothalamus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myers, R D -- McCaleb, M L -- New York, N.Y. -- Science. 1980 Aug 29;209(4460):1035-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403866" target="_blank"〉PubMed〈/a〉

    Description: The human genes for growth hormone (GH), chorionic somatomammotropin (CSH), and a third growth hormone-like gene (GHL) have been located on chromosome 17 in humans. DNA fragments of 2.6, 2.8, and 9.5 kilobase pairs containing GH, CSH, and GHL, respectively, were identified in human genomic DNA, and a 7.5-kilobase DNA fragment related to growth hormone DNA sequences was found in mouse cells. In somatic hybrids of human and mouse cells containing reduced numbers of human chromosomes, but a normal complement of mouse chromosomes, the mouse, 7.5-kolobase DNA fragment was always present, whereas the 2.6-, 2.8-, and 9.5-kilobase human fragments were present only when human chromosome 17 was also present.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owerbach, D -- Rutter, W J -- Martial, J A -- Baxter, J D -- Shows, T B -- New York, N.Y. -- Science. 1980 Jul 11;209(4453):289-92.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384802" target="_blank"〉PubMed〈/a〉

Long-term, but not short-term, antidepressant treatment decreases the numbers of both serotonin and beta-adrenergic receptors.

    Description: The growth of the MCF-7 human breast cancer cell line is unresponsive to the presence of estrogen in culture media. Paradoxically, in nude mice, growth of these cells and formation of solid tumors are dependent on estrogen. Tumors fail to develop in ovariectomized mice, but do develop in intact mice and in ovariectomized mice given estrogen. Primary cultures derived from MCF-7 tumors revert to unresponsiveness to estrogen. However, when these cultures are again transplanted into nude mice, estrogen is required for tumor formation. The continuous culture, the solid tumor, and the primary cultures therefrom have similar estrogen-binding capacities and affinities. These results indicate that mammary carcinoma cell growth in vivo is subject to inhibition that can be overcome by estrogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shafie, S M -- New York, N.Y. -- Science. 1980 Aug 8;209(4457):701-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6994231" target="_blank"〉PubMed〈/a〉

    Description: Forty children were given a diet free of artificial food dyes and other additives for 5 days. Twenty of the children had been classified as hyperactive by scores on the Conners Rating Scale and were reported to have favorable responses to stimulant medication. A diagnosis of hyperactivity had been rejected in the other 20 children. Oral challenges with large doses (100 or 150 milligrams) of a blend of FD & C approved food dyes or placebo were administered on days 4 and 5 of the experiment. The performance of the hyperactive children on paired-associate learning tests on the day they received the dye blend was impaired relative to their performance after they received the placebo, but the performance of the nonhyperactive group was not affected by the challenge with the food dye blend.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swanson, J M -- Kinsbourne, M -- New York, N.Y. -- Science. 1980 Mar 28;207(4438):1485-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7361102" target="_blank"〉PubMed〈/a〉

    Description: Aequorin signals in mammalian heart muscle cells reveal the existence of two temporally distinct processes that increase cytoplasmic calcium ions after membrane excitation. The differential dependence of these processes on the pattern of stimulation suggests that the first process is, or is closely related to, calcium entry through the surface membrane and that the second is calcium release from intracellular storage sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wier, W G -- New York, N.Y. -- Science. 1980 Mar 7;207(4435):1085-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355274" target="_blank"〉PubMed〈/a〉

    Description: In rats, multiple daily amphetamine injections (2.5 milligrams per kilogram of body weight, injected subcutaneously every 4 hours for 5 days) resulted in a progressive augmentation in response, characterized by a more rapid onset and an increased magnitude of stereotypy. By contrast, offset times of both the stereotypy and the poststereotypy hyperactivity periods were markedly shortened. When the animals were retested with the same dose of amphetamine 8 days after the long-term treatment was discontinued, the time of offset of the stereotypy and hyperactivity phases had recovered to values found with short-term amphetamine treatment, whereas the more rapid onset of stereotypy persisted. Brain monoamine and amphetamine concentrations and tyrosine hydroxylase activity were determined in comparably treated rats at times corresponding to the behavioral observations. The behavioral data indicate that enhanced responsiveness to amphetamine following its repeated administration may contribute to the development of amphetamine psychosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Segal, D S -- Weinberger, S B -- Cahill, J -- McCunney, S J -- New York, N.Y. -- Science. 1980 Feb 15;207(4433):905-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7188815" target="_blank"〉PubMed〈/a〉

    Description: Mice inoculated with herpes simplex virus (type 1) by the lip or corneal route and then passively immunized with rabbit antibody to herpes simplex virus developed a latent infection in the trigeminal ganglia within 96 hours. Neutralizing antibody to herpes simplex virus was cleared from the circulation and could not be detected in most of these mice after 2 months. Examination of ganglia from the antibody-negative mice revealed latent virus in over 90 percent of the animals, indicating that serum neutralizing antibody is not necessary to maintain the latent state. When the lips or corneas of these mice were traumatized, viral reactivation occurred in up to 90 percent of the mice, as demonstrated by the appearance of neutralizing antibody. This study provides a model for identifying factors that trigger viral reactivation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sekizawa, T -- Openshaw, H -- Wohlenberg, C -- Notkins, A L -- New York, N.Y. -- Science. 1980 Nov 28;210(4473):1026-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6254149" target="_blank"〉PubMed〈/a〉

    Description: Three-month-old infants learned to activate an overhead crib mobile by operant footkicking and received a visual reminder of the event (a "reactivation treatment") 2 weeks later, after forgetting had occurred. Subsequent manifestation of the association was a monotonic increasing function of time since the reactivation treatment, and performance of infants tested 8 hours after the remainder was related to the time spent sleeping in the interim (r = 0.75). These data demonstrate that normal retrieval is time-dependent. Moreover, individual data suggest that retrieval may be continuous rather than discontinuous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fagen, J W -- Rovee-Collier, C -- MH 32307/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1983 Dec 23;222(4630):1349-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6658456" target="_blank"〉PubMed〈/a〉

    Description: The number of transcripts of the cellular oncogene ras, which is homologous to the transforming gene of Harvey sarcoma virus, increases during liver regeneration in rats. The increase in these transcripts in liver polysomal polyadenylated RNA occurs at the time of activation of DNA synthesis during the regenerative process induced by partial hepatectomy or carbon tetrachloride injury. The number of ras transcripts returns to basal levels within 72 hours. These observations show that transcription of a cellular oncogene increases in a regulated way in a nonneoplastic growth process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goyette, M -- Petropoulos, C J -- Shank, P R -- Fausto, N -- New York, N.Y. -- Science. 1983 Feb 4;219(4584):510-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6297003" 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〉

    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: 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〉

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: The interspecific fusion of normal bovine lymphocytes with a nonsecreting mouse hybridoma produced stable cell lines secreting bovine immunoglobulins. One of these lines has continued to secrete immunoglobulin G1 (5 to 10 micrograms per milliliter) for over 16 months. The bovine x mouse hybrid cells can be expected to provide bovine monoclonal immunoglobulins for sequencing studies and for use as serological standards as well as to provide messenger RNA for cloning bovine immunoglobulin genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srikumaran, S -- Guidry, A J -- Goldsby, R A -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):522-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6403985" 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: A twofold thickening of capillary basement membranes of rat retinas resulting from dietary galactose was prevented by sorbinil, an inhibitor of aldose reductase. Since the basement membrane thickening was ultrastructurally similar to that typical of diabetic retinopathy, it may indicate changes in vessel permeability and susceptibility to hemorrhage. Galactosemic rats should be useful models for studying basement membrane-related complications of diabetes and for examining the potential biochemical regulation of basement membrane synthesis by aldose reductase inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robison, W G Jr -- Kador, P F -- Kinoshita, J H -- New York, N.Y. -- Science. 1983 Sep 16;221(4616):1177-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6612330" target="_blank"〉PubMed〈/a〉

    Description: Aplysiatoxin and debromoaplysiatoxin, which are isolated from the seaweed, Lyngbya gracilis, differ in their chemical structure only by the presence or absence of a bromine residue in the hydrophilic region. The function and the structure-activity relation of the hydrophilic region are not known. Aplysiatoxin increased malignant transformation, stimulated DNA synthesis, and inhibited the binding of phorbol-12,13-dibutyrate and epidermal growth factor to cell receptors. Debromoaplysiatoxin inhibited the binding of these two substances as strongly as aplysiatoxin but did not increase malignant transformation or stimulate DNA synthesis. These results indicate that a slight change in the chemical structure of the hydrophilic region of aplysiatoxin affects its abilities to increase cell transformation and stimulate DNA synthesis and that the abilities of the tumor promoters to inhibit the binding of phorbol-12,13-dibutyrate and epidermal growth factor are dissociable from their abilities to increase cell transformation and stimulate DNA synthesis under some circumstances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shimomura, K -- Mullinix, M G -- Kakunaga, T -- Fujiki, H -- Sugimura, T -- New York, N.Y. -- Science. 1983 Dec 16;222(4629):1242-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316505" target="_blank"〉PubMed〈/a〉

    Description: The structures of three proteins that regulate gene expression have been determined recently and suggest how these proteins may bind to their specific recognition sites on the DNA. One protein (Cro) is a repressor of gene expression, the second (CAP) usually stimulates gene expression, and the third (lambda repressor) can act as either a repressor or an activator. The three proteins contain a substructure consisting of two consecutive alpha helices that is virtually identical in each case. Structural and amino acid sequence comparisons suggest that this bihelical fold occurs in a number of proteins that regulate gene expression, and is an intrinsic part of the DNA-protein recognition event. The modes of repression and activation by Cro and lambda repressor are understood reasonably well, but the mode of action of CAP is still unclear.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeda, Y -- Ohlendorf, D H -- Anderson, W F -- Matthews, B W -- GM20066/GM/NIGMS NIH HHS/ -- GM28138/GM/NIGMS NIH HHS/ -- GM30894/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 9;221(4615):1020-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308768" target="_blank"〉PubMed〈/a〉

    Description: After administration of tyrosine, total concentration of biopterin, the cofactor for tyrosine hydroxylase, was increased in the striatum, adrenal glands, and serum of rats, and in the serum of humans. Serum biopterin is lower in patients with Parkinson's disease than in normal controls. After oral administration of tyrosine, the increase in serum biopterin concentration was smaller in patients with Parkinson's disease (less than twofold) than in healthy controls (three-to sevenfold). These results suggest that tyrosine may have a regulatory role in biopterin biosynthesis and that patients with Parkinson's disease may have some abnormality in the regulation of biopterin biosynthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamaguchi, T -- Nagatsu, T -- Sugimoto, T -- Matsuura, S -- Kondo, T -- Iizuka, R -- Narabayashi, H -- New York, N.Y. -- Science. 1983 Jan 7;219(4580):75-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6849120" target="_blank"〉PubMed〈/a〉

    Description: Regulation of hemoglobin synthesis depends in part on the population of cells available for erythroid differentiation. Mouse erythroleukemia cells were cloned, and the clones were induced with dimethyl sulfoxide to test the relative induction of beta minor and beta major synthesis. Cells of line 745 produced approximately 35 percent beta minor after induction, and 39 clones of line 745 produced from 23 to 61 percent beta minor. Further subcloning of the clone that produced 61 percent beta minor led to three subclones, all of which produced more than 90 percent beta minor. Thus one kind of hemoglobin regulation occurs at the cellular level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alter, B P -- Goff, S C -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):647-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6928071" target="_blank"〉PubMed〈/a〉

    Description: Experiments were designed to test the hypothesis that pituitary hormones may be delivered directly to the brain. Concentrations of adrenocorticotropic hormone (ACTH) in the plasma were determined in blood samles obtained simultaneously from the carotid artery, the sagittal sinus, and the jugular vein of three awake sheep. Seizures were induced electrically to stimulate ACTH secretion, and at precise intervals thereafter several simultaneous comparisons were made in each animal. In many of the post-seizure comparisons, the ACTH plasma concentrations within the sagital sinus exceeded those within the carotid artery as well as those within the jugular vein, indicating that this hormone was released from the pituitary and carried directly through capillary beds of brain to the venous blood within the sagittal sinus. The experiment was repeated in one hypophysectomized sheep and, in this animal, ACTH concentration in the plasma was reduced, but that in the sagittal sinus still was elevated after the seizure, an indication that some ACTH (or ACTH-like material) was released from the brain itself.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bergland, R -- Blume, H -- Hamilton, A -- Monica, P -- Paterson, R -- New York, N.Y. -- Science. 1980 Oct 31;210(4469):541-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6252607" target="_blank"〉PubMed〈/a〉

    Description: Suckling is the only behavior that is common among mammals. In newborn albino rats it is originally elicited by amniotic fluid deposited by the mother during parturition. Subsequent suckling is stimulated by saliva deposited on the nipples by the infant rats. Internal controls over the volume of milk suckled do not appear until infant rats are about 2 weeks of age at which time gastric distension, milk, systemic dehydration, and intestinal hormone cholecystokinin suppress milk intake derived through suckling. The development of controls over suckling appetite appears to parallel that of consummatory control. Until about 2 weeks of age infant rats choose to suckle a nonlactating nipple with the same frequency as a lactating nipple. Thereafter, the lactating nipple is unanimously chosen. These studies suggest differences and commonalities in the suckling behavior of laboratory rats and other mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blass, E M -- Teicher, M H -- AM-18560/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 3;210(4465):15-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6997992" target="_blank"〉PubMed〈/a〉

Analysis of membrane conductance fluctuations induced by iontophoresis of glycine and gamma-aminobutyric acid indicates a mean inhibitory channel lifetime of 7.15 milliseconds. The results thus suggest that the relaxation kinetics of activated inhibitory channels are rate-limiting during decay of the inhibitory postsynaptic current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faber, D S -- Korn, H -- New York, N.Y. -- Science. 1980 May 9;208(4444):612-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6245449" target="_blank"〉PubMed〈/a〉

    Description: Rates of tyrosine and lysine transport and incorporation into protein were measured in control and undernourished weanling rats. Undernutrition was induced by feeding lactating dams a low protein diet (12 percent casein) from birth to day 21. At weaning, body and brain weights of undernourished rats were 50 percent and 88 percent, respectively, of control values. Lysine and tyrosine transport rates into skeletal muscle were reduced by over 75 percent, more than twice the reduction seen in brain. Rates of amino acid incorporation into muscle protein were reduced by approximately 50 percent; the change in rate of incorporation into brain protein was not statistically significant. These data indicate that, in spite of marked retardation of amino acid transport into brain, the brain seems fully capable of maintaining normal rates of protein synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freedman, L S -- Samuels, S -- Fish, I -- Schwartz, S A -- Lange, B -- Katz, M -- Morgano, L -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):902-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6766565" target="_blank"〉PubMed〈/a〉

    Description: In rats that were fasted for 2 to 3 days there was a decline in hypothalamic, but not pituitary, beta-endorphin. There was no change in pituitary or hypothalamic adrenocorticotropin content as a result of fasting. Endogenous opiates may be involved in physiological adaptation to fasting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gambert, S R -- Garthwaite, T L -- Pontzer, C H -- Hagen, T C -- New York, N.Y. -- Science. 1980 Dec 12;210(4475):1271-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6254156" target="_blank"〉PubMed〈/a〉

    Description: Maternal pain thresholds in rats were determined during various stages of pregnancy and parturition by measuring the intensity of electric shock that elicited reflexive jumping. There was a gradual rise in the pain threshold between 16 and 4 days prior to parturition and a more abrupt rise 1 to 2 days before that event. This increase was abolished by long-term administration of the narcotic antagonist naltrexone. The endorphin system is thus an important component of intrinsic mechanisms that modulate responsiveness to aversive stimuli. The data also demonstrate the activation during pregnancy of an endorphin system that is apparently quiescent in nonpregnant female rats treated the same way.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gintzler, A R -- NIMH GRANT DA01771/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 10;210(4466):193-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7414330" target="_blank"〉PubMed〈/a〉

    Description: In concentrates of water produced in a laboratory simulation of a drinking water treatment process, direct-acting, nonvolatile mutagens were readily detected by means of the Ames Salmonella test. The mutagens were shown to be produced by the chlorination process. Treatment of the water with chloramine resulted in less mutagenic activity than treatment with free chlorine. Dechlorination of drinking water with sulfite sharply reduced the mutagenic activity. Treatment with sulfur dioxide is proposed as an effective, inexpensive method of reducing the direct-acting mutagenic activity of drinking water and of aqueous industrial effluents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheh, A M -- Skochdopole, J -- Koski, P -- Cole, L -- New York, N.Y. -- Science. 1980 Jan 4;207(4426):90-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6985746" target="_blank"〉PubMed〈/a〉

    Description: A classical conditioning paradigm was used to demonstrate that male rats can learn to secrete luteinizing hormone and testosterone in anticipation of sexual activity. Sexually naive males were exposed to a neutral stimulus and then to a sexually receptive female once daily. After exposure to the paired stimuli for 14 trials, the neutral stimulus was as effective as the female in triggering luteinizing hormone and testosterone secretion. These findings provide two novel perspectives on the control of reproductive hormone secretion in male rats: (i) environmental cues, which males learn to associate with sexual activity, induce the secretion of hormones that regulate pituitary-testis function, and (ii) classical conditioning may be used as a noninvasive method to evoke functional alterations in the secretion of luteinizing hormone and presumably the neuroendocrine pathways that mediate its release.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graham, J M -- Desjardins, C -- HD-13470/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 28;210(4473):1039-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434016" target="_blank"〉PubMed〈/a〉

    Description: The teratogenicity of alcohol has been demonstrated in humans through clinical studies, behavioral studies, and epidemiologic studies, and in animals through controlled laboratory experiments. In humans exposed to alcohol during gestation the effects can range from fetal alcohol syndrome in some offspring of chronic alcoholic women to reduced average birth weight in offspring of women reporting an average consumption of two to three drinks or more per day. The behavioral effects of such exposure may range from mental retardation in children with fetal alcohol syndrome to milder developmental and behavioral effects in infants born to social drinkers. In animals, exposure to alcohol in utero may result in death, malformation, and growth deficiency as well as behavioral and developmental abnormalities. The mechanisms of impairment and related risk factors are yet to be elucidated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Streissguth, A P -- Landesman-Dwyer, S -- Martin, J C -- Smith, D W -- New York, N.Y. -- Science. 1980 Jul 18;209(4454):353-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6992275" target="_blank"〉PubMed〈/a〉

The dose-response curve for naloxone against seizure activity induced by leucine enkephalin was the same as that in gamma-hydroxybutyrate-induced petit mal.

    Description: When young adults detected auditory stimuli at split-second intervals, different components of the event-related brain potentials showed markedly different speeds of recovery. The P3 component (latency 300 to 350 milliseconds) was fully recovered at intervals of less than 1.0 second, while the N1--P2 components (latencies 100 to 180 milliseconds) were markedly attenuated with stimulus repetition even at longer interstimulus intervals. Thus, the N1--P2 recovers much more slowly than a subject's ability to evaluate signals, whereas the P3 appears to be generated at the same high rates as the decision processes with which it is associated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Woods, D L -- Hillyard, S A -- Courchesne, E -- Galambos, R -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):655-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352278" target="_blank"〉PubMed〈/a〉

    Description: Inhibiting protein synthesis by incubating C6-2B rat astrocytoma cells with cycloheximide or emetine for periods up to 24 hours caused a progressive decrease in the accumulation of adenosine 3',5'-monophosphate (cyclic AMP) when the cells were challenged for 30 minutes with 100 microM forskolin. In contrast, cholera toxin-stimulated (6 nM, 3 hours) cyclic AMP accumulation was not diminished in cycloheximide-treated cells, and cyclic AMP was only minimally diminished in response to a 30-minute challenge with 10 microM (-)-isoproterenol. These experiments suggest the presence of a previously unrecognized cyclase component, which is essential for forskolin-stimulated cyclic AMP accumulation and has a shorter half-life than the beta-adrenergic receptor, the guanine nucleotide regulatory proteins, or the cyclase catalytic component.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brooker, G -- Pedone, C -- Barovsky, K -- HL 06330/HL/NHLBI NIH HHS/ -- HL 28940/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1169-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6190226" target="_blank"〉PubMed〈/a〉

    Description: The mouse neuroblastoma-rat glioma hybrid cell line NG108-15 was used to study the acute and chronic interaction of ethanol with intact neural cells. In the short term, ethanol inhibited opiate receptor binding, but after long-term exposure the cells exhibited an apparent adaptive increase in the number of opiate binding sites; this was reversible when ethanol was withdrawn. High concentrations of ethanol (200 mM) increased opiate binding after 18 to 24 hours, whereas lower concentrations (25 to 50 mM) produced similar changes after 2 weeks. This model system has potential for exploring the cellular and molecular mechanisms underlying ethanol intoxication, tolerance, and withdrawal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Charness, M E -- Gordon, A S -- Diamond, I -- New York, N.Y. -- Science. 1983 Dec 16;222(4629):1246-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316506" target="_blank"〉PubMed〈/a〉

    Description: Anti-idiotype reagents that recognize a common idiotype associated with the combining site of antibodies to hepatitis B surface antigen (anti-HBs) were used to manipulate the immune response to hepatitis B surface antigen in BALB/c mice. The injection of antibodies to the idiotype before antigenic stimulation resulted in an increase in the number of cells secreting immunoglobulin M antibodies to hepatitis B surface antigen. Anti-HBs-secreting cells were also induced by administration of antibodies to the idiotype without subsequent antigen exposure. These findings indicate that the immune response to hepatitis B surface antigen in mice is regulated through an idiotype-anti-idiotype network.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kennedy, R C -- Adler-Storthz, K -- Henkel, R D -- Sanchez, Y -- Melnick, J L -- Dreesman, G R -- New York, N.Y. -- Science. 1983 Aug 26;221(4613):853-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6603657" target="_blank"〉PubMed〈/a〉

    Description: The immediate induction of the full complement of maternal behavior in nonpregnant ewes primed with estrogen and progesterone has been obtained after 5 minutes of vaginal-cervical stimulation. A similar period of such stimulation given to recently parturient ewes, after the development of selective bonding to their own lambs, reversed their rejection behavior of alien lambs and produced a state of plasticity in maternal behavior, such that ewes receiving vaginal stimulation would accept and adopt alien lambs. These findings implicate vaginal-cervical stimulation as playing a role in the onset of maternal behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keverne, E B -- Levy, F -- Poindron, P -- Lindsay, D R -- New York, N.Y. -- Science. 1983 Jan 7;219(4580):81-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6849123" target="_blank"〉PubMed〈/a〉

    Description: Compared to nonpregnant controls, pregnant mice injected with phenobarbital had lower concentrations of the drug in the plasma but equivalent concentrations in the brain. In spite of the similar concentrations in the brain, the behavioral response to phenobarbital was greater for pregnant than nonpregnant mice. These results suggest that the concentration of phenobarbital in the plasma, which is commonly used as a basis for adjusting phenobarbital dosage during pregnancy, is not an appropriate indicator of the dynamics of the drug.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Middaugh, L D -- Zemp, J W -- Boggan, W O -- AA03532/AA/NIAAA NIH HHS/ -- DA00041/DA/NIDA NIH HHS/ -- DA01750/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):534-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836299" target="_blank"〉PubMed〈/a〉

    Description: The transport of specific proteins in regenerating optic fibers of goldfish depends on the presence or absence of the optic tectum. When optic fibers were allowed to contact the tectum, amounts of rapidly transported proteins having molecular weights between 120,000 and 160,000 increased, and a species of molecular weight 26,000 reverted to normal levels. When nerves were prevented from contacting the tectum, the amount of the 26,000-molecular weight protein remained high for months. Amounts of other transported proteins, in particular a group of acidic components of molecular weight 44,000 to 49,000 that increase greatly at early stages of regeneration, proved to be independent of the tectum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benowitz, L I -- Yoon, M G -- Lewis, E R -- R01NS16943/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 Oct 14;222(4620):185-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6194562" target="_blank"〉PubMed〈/a〉

    Description: Two-month-old infants discriminated complex sinusoidal patterns that varied in the duration of their initial frequency transitions. Discrimination of these nonspeech sinusoidal patterns was a function of both the duration of the transitions and the total duration of the stimulus pattern. This contextual effect was observed even though the information specifying stimulus duration occurred after the transitional information. These findings parallel those observed with infants for perception of synthetic speech stimuli. Specialized speech processing capacities are thus not required to account for infants' sensitivity to contextual effects in acoustic signals, whether speech or nonspeech.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jusczyk, P W -- Pisoni, D B -- Reed, M A -- Fernald, A -- Myers, M -- HD-11915/HD/NICHD NIH HHS/ -- HD-15795-02/HD/NICHD NIH HHS/ -- MH-24027/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1983 Oct 14;222(4620):175-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6623067" target="_blank"〉PubMed〈/a〉

Evidence is presented showing that stress potentiates cocaine stereotypy as well. These effects of stress were found to be particular to stress that could not be controlled in that rats receiving an identical amount of stress from footshock, but allowed to control its duration, displayed no more stereotypy than did nonstressed rats. These findings have implications for the role of stress and coping in amphetamine and cocaine psychoses, endogenous psychoses, and some forms of schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacLennan, A J -- Maier, S F -- New York, N.Y. -- Science. 1983 Mar 4;219(4588):1091-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6681679" target="_blank"〉PubMed〈/a〉

This experiment demonstrated that the rate at which synapses were replaced by sprouting after a lesion declined dramatically from 35 to 90 days of age. Thus, the juvenile period of the rat's life is marked by a considerable change in neuronal plasticity.

    Description: Lysates of the protozoan parasite Entamoeba histolytica altered active electrolyte transport when present on the serosal surface of rabbit ileum and rat colon. The lysate-induced effects on electrolyte transport were similar to those caused by serotonin, and were blocked by bufotenine, an analog known to inhibit the action of serotonin. The transport effects were partially inhibited by antibody to serotonin. The amebic lysates were shown to contain serotonin by radioimmunoassay, high-performance liquid chromatography, and thin-layer chromatography. These results suggest that the serotonin present in Entamoeba histolytica may be important in the diarrhea seen in amebiasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGowan, K -- Kane, A -- Asarkof, N -- Wicks, J -- Guerina, V -- Kellum, J -- Baron, S -- Gintzler, A R -- Donowitz, M -- AM26523/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1983 Aug 19;221(4612):762-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308760" target="_blank"〉PubMed〈/a〉

    Description: After transport in the blood and implantation in the microcirculation, metastatic tumor cells must invade the vascular endothelium and underlying basal lamina. Mouse B16 melanoma sublines were used to determine the relation between metastatic properties and the ability of the sublines to degrade enzymatically the sulfated glycosaminoglycans present in the extracellular matrix of cultured vascular endothelial cells. Highly invasive and metastatic B16 sublines degraded matrix glycosaminoglycans faster than did sublines of lower metastatic potential. The main products of this matrix degradation were heparan sulfate fragments. Intact B16 cells (or their cell-free homogenates) with a high potential for lung colonization degraded purified heparan sulfate from bovine lung at higher rates than did B16 cells with a poor potential for lung colonization. Analysis of the degradation fragments indicated that B16 cells have a heparan sulfate endoglycosidase. Thus the abilities of B16 melanoma cells to extravasate and successfully colonize the lung may be related to their capacities to degrade heparan sulfate in the walls of pulmonary blood vessels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakajima, M -- Irimura, T -- Di Ferrante, D -- Di Ferrante, N -- Nicolson, G L -- R01-AM-26482/AM/NIADDK NIH HHS/ -- R01-CA-28867/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 6;220(4597):611-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6220468" target="_blank"〉PubMed〈/a〉

    Description: The uninephrectomized rat given desoxycorticosterone (DOC) provides a classic model of "sodium-dependent" hypertension. In such rats, the extent to which a given dietary intake of sodium induced an increase in blood pressure depended on whether or not the anionic component of the sodium salt was chloride. With normal and high dietary intakes of sodium, sodium chloride induced increases in blood pressure much greater than that induced by approximately equimolar amounts of sodium bicarbonate, sodium ascorbate, or a combination of sodium bicarbonate and sodium ascorbate. A normal amount of dietary sodium chloride induced hypertension, whereas an equimolar amount of sodium bicarbonate did not increase blood pressure. This difference could not be attributed to differences in sodium or potassium balances, weight gain, or caloric intake. The DOC model of "sodium-dependent" hypertension might better be considered sodium chloride-dependent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurtz, T W -- Morris, R C Jr -- R01-AM32631-01/AM/NIADDK NIH HHS/ -- RR-00079/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1983 Dec 9;222(4628):1139-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6648527" target="_blank"〉PubMed〈/a〉

    Description: The antigen defined by a rat monoclonal antibody directed to a Burkitt lymphoma cell line was identified as globotriaosylceramide [Gal alpha (1 leads to 4)-Gal beta (1 leads to 4)-Glc beta (1 leads to 1)-ceramide]. The antibody demonstrated a strict steric specificity since it did not react with globoisotriaosylceramide [Gal alpha (1 leads to 3)-Gal beta (1 leads to 4)-Glc beta (1 leads to 1)-ceramide], the positional isomer of the antigen associated with the Burkitt lymphoma. Chemical analysis of various Burkitt lymphoma cell lines revealed that the Burkitt lymphoma cells contained more than 100 times as much of the glycolipid antigen as was found in other human lymphoma and leukemia cell lines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nudelman, E -- Kannagi, R -- Hakomori, S -- Parsons, M -- Lipinski, M -- Wiels, J -- Fellous, M -- Tursz, T -- CA 19224/CA/NCI NIH HHS/ -- CA 20026/CA/NCI NIH HHS/ -- GM 23100/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):509-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836295" target="_blank"〉PubMed〈/a〉

    Description: Perceptual sensitivity to a visual target presented in a random continuous sequence of targets and nontargets decreased rapidly over time when stimuli were highly degraded visually but not when moderately degraded or undegraded. Large declines in sensitivity, independent of changes in response criterion, were found after only 5 minutes of observation. These rapid decrements of sensitivity to degraded targets seem to result from demands on the limited capacity of visual attention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nuechterlein, K H -- Parasuraman, R -- Jiang, Q -- 784040-29867-5/PHS HHS/ -- MH 30911/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):327-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836276" target="_blank"〉PubMed〈/a〉

    Description: Resonance Raman spectra of photolyzed carbonmonoxyhemoglobin obtained with 10-nanosecond pulses are compared with the spectra of photolyzed carbonmonoxyhemoglobin stabilized at 80 K. In comparing the deoxy with the photodissociated species, the changes in the Raman spectra are the same for these two experimental regimes. These results show that at ambient and cryogenic temperatures the heme pocket in liganded hemoglobin is significantly different from that of deoxyhemoglobin. It is concluded that measurements of the properties of intermediate species from photodissociated hemoglobin stabilized at low temperatures can be used to probe the short-lived metastable forms of hemoglobin present after photodissociation under biologically relevant solution conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ondrias, M R -- Friedman, J M -- Rousseau, D L -- New York, N.Y. -- Science. 1983 May 6;220(4597):615-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836305" target="_blank"〉PubMed〈/a〉

    Description: Cells of the murine plasmacytoid line MOPC-315 synthesize two distinct immunoglobulin light chains: a normal lambda II protein, which is incorporated into secretory and surface-bound immunoglobulin, and a truncated, nonfunctional lambda I protein found only in the cytoplasm. Idiotype-specific suppressor T lymphocytes selectively inhibit the expression of both lambda II- and lambda I-specific messenger RNA by MOPC-315 cells. This finding demonstrates that phenotypically excluded light chain genes can be subject to immunoregulatory control and suggests that the expression of divergent lambda isotypes may be coordinately regulated in immunoglobulin-secreting cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parslow, T G -- Milburn, G L -- Lynch, R G -- Granner, D K -- AM25295/AM/NIADDK NIH HHS/ -- CA28848/CA/NCI NIH HHS/ -- CA32275/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Jun 24;220(4604):1389-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6222474" target="_blank"〉PubMed〈/a〉

    Description: Fusion of immortal cell lines with normal human fibroblasts or certain other immortal cell lines yields hybrids having limited division potential. Cellular immortality was found to be a recessive phenotype in hybrids. It was also found that at least two separate events in the normal cell genome can result in immortality. In fusions involving certain immortal parent cells, these events can be complemented to result in hybrids with finite division capacity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pereira-Smith, O M -- Smith, J R -- AG 03262/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 2;221(4614):964-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6879195" target="_blank"〉PubMed〈/a〉

    Description: Nine new isolates of human T-cell leukemia-lymphoma virus (HTLV) were obtained from cells of seven patients with malignancies of mature T cells and from two clinically normal relatives of a T-cell leukemia patient. These people were from the United States, Israel, the West Indies, and Japan. The virus was detected in the fresh T cells and was isolated from the established T-cell lines. Each isolate is closely related to the first HTLV isolate, and all the new HTLV isolates were transmitted into normal human T cells obtained from the umbilical cord blood of newborns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popovic, M -- Sarin, P S -- Robert-Gurroff, M -- Kalyanaraman, V S -- Mann, D -- Minowada, J -- Gallo, R C -- New York, N.Y. -- Science. 1983 Feb 18;219(4586):856-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6600519" target="_blank"〉PubMed〈/a〉

    Description: Steroid hormones, when complexed to their receptors, recognize and bind specific DNA sequences and subsequently induce increased levels of transcription. The mechanisms of steroid hormone action were analyzed by constructing chimeric DNA molecules from portions of mouse mammary tumor virus envelope and long terminal repeat (LTR) regions ligated to the thymidine kinase (tk) gene of herpes simplex virus. This construction allowed the tk gene to be expressed in a hormone-responsive fashion upon transfection into Ltk- cells. Comparison of transcription data with in vitro binding data showed that hormone-responsive transcription can be directly correlated to the presence of steroid hormone receptor binding sites on the DNA. There are at least two such receptor binding sites in the LTR region, one between -202 and -137 and another between -137 and -50 base pairs from the RNA cap site, as well as a site near the 5' end of the envelope region. These results strengthen the hypothesis that steroid-receptor complexes regulate genes primarily by binding to DNA sites near the promoter region and thereby modulate transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfahl, M -- McGinnis, D -- Hendricks, M -- Groner, B -- Hynes, N E -- New York, N.Y. -- Science. 1983 Dec 23;222(4630):1341-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6318311" target="_blank"〉PubMed〈/a〉

    Description: The issue of whether sleep is physiologically necessary has been unresolved because experiments that reported deleterious effects of sleep deprivation did not control for the stimuli used to prevent sleep. In this experiment, however, experimental and control rats received the same relatively mild physical stimuli, but stimulus presentations were timed to reduce sleep severely in experimental rats but not in controls. Experimental rats suffered severe pathology and death; control rats did not.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rechtschaffen, A -- Gilliland, M A -- Bergmann, B M -- Winter, J B -- MH-18428/MH/NIMH NIH HHS/ -- MH-4151/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 8;221(4606):182-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857280" target="_blank"〉PubMed〈/a〉
