    Reexamination of acoustic evidence in the Kennedy assassination. Committee on Ballistic Acoustics, National Research Council (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-08
    Description: Sounds recorded in Dallas at the time of the assassination of John F. Kennedy were analyzed by two research groups, whose reports formed the basis for the opinion that two gunmen fired at President Kennedy. These reports and the acoustic evidence have been studied by the Committee on Ballistic Acoustics, and further acoustic analyses, including sound spectrograms, have been performed. The committee finds that the acoustic data do not support a conclusion that a second gunman was involved in the assassination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉New York, N.Y. -- Science. 1982 Oct 8;218(4568):127-33.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6750789" target="_blank"〉PubMed〈/a〉

    Stereoisomers of N-allylnormetazocine: phencyclidine-like behavioral effects in squirrel monkeys and rats (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-08
    Description: (+/-)-N-Allylnormetazocine is a benzomorphan opioid with psychotomimetic effects. The pure stereoisomers of this compound, as well as the racemic mixture, were compared to phencyclidine for their behavioral effects on squirrel monkeys and rats trained to discriminate phencyclidine from saline. Dose-response determinations were made for responses to phencyclidine, to a racemic mixture of N-allylnormetazocine, and to the pure levo and dextro isomers of N-allylnormetazocine. In both rats and monkeys, the dextro isomer and the racemic mixture produced dose-dependent responses appropriate for phencyclidine; the levo isomer did not produce the responses appropriate for phencyclidine at any of the doses tested. In both species, the levo isomer was more potent than the dextro isomer in decreasing the rate of responding. Thus racemic N-allylnormetazocine is a mixture of compounds that produce different behavioral effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brady, K T -- Balster, R L -- May, E L -- DA-00490/DA/NIDA NIH HHS/ -- DA-01442/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):178-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6274022" target="_blank"〉PubMed〈/a〉

    Ethanol in low doses augments calcium-mediated mechanisms measured intracellularly in hippocampal neurons (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-15
    Description: The electrophysiological effects of ethanol in low doses (5 to 20 millimoles per liter or 23 to 92 milligrams per 100 milliliters) were examined intracellularly in CA1 cells of rat hippocampus in vitro. Inhibitory and excitatory postsynaptic potentials were increased when ethanol was applied to the respective synaptic terminal regions. Postsynaptically, ethanol caused a moderate hyperpolarization with increased membrane conductance, even when synaptic transmission was blocked. Ethanol augmented the hyperpolarization that followed repetitive firing or that followed the eliciting of calcium spikes in the presence of tetrodotoxin, but not the rapid afterhyperpolarization in calcium-free medium. Ethanol appears to augment calcium-mediated mechanisms both pre- and postsynaptically.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlen, P L -- Gurevich, N -- Durand, D -- R01 NS16660-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 15;215(4530):306-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053581" target="_blank"〉PubMed〈/a〉

    Theory and observation in cultural transmission (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-01
    Description: Cultural phenomena may show considerable stability over time and space. Transmission mechanisms responsible for their maintenance are worthy of theoretical and empirical inquiry; they are complex and each possible pathway has different effects on evolutionary stability of traits, as can be shown theoretically. A survey designed to evaluate the importance of some components of cultural transmission on a variety of traits showed that religion and politics are mostly determined in the family, a mode of transmission which guarantees high evolutionary stability and maintenance of high variation between and within groups.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cavalli-Sforza, L L -- Feldman, M W -- Chen, K H -- Dornbusch, S M -- 10452/PHS HHS/ -- 20467/PHS HHS/ -- 20816/PHS HHS/ -- New York, N.Y. -- Science. 1982 Oct 1;218(4567):19-27.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123211" target="_blank"〉PubMed〈/a〉

    Substantia nigra: site of anticonvulsant activity mediated by gamma-aminobutyric acid (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-17
    Description: Localization of the anatomic substrate for anticonvulsant activity mediated by gamma-aminobutyric acid (GABA) was examined using intracerebral injections of GABA agonists. Blockade of tonic hindlimb extension in the maximal electroshock test and blockade of tonic and clonic seizures produced by pentylenetetrazole and bicuculline were obtained by elevating GABA in the ventral midbrain tegmentum. Elevation of GABA in forebrain and hindbrain areas had no effect on convulsant activity. Blockade of tonic and clonic seizures was also obtained after microinjections of the direct GABA receptor agonist, muscimol, into the midbrain. The substantia nigra was identified as the critical midbrain site for GABA-mediated anticonvulsant activity. Local injection of GABA agonists into the midbrain provided seizure protection without a widespread augmentation of GABA-mediated activity throughout the brain and without impairing either alertness or motor function. Synapses in the substantia nigra appear to represent an important control mechanism for inhibiting the propagation of generalized convulsions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iadarola, M J -- Gale, K -- DA 02206/DA/NIDA NIH HHS/ -- MH32359/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 17;218(4578):1237-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146907" target="_blank"〉PubMed〈/a〉

    Description: Local administration of human growth hormone in vivo to the cartilage growth plate of the proximal tibia of hypophysectomized rats resulted in accelerated longitudinal bone growth. This finding suggests that growth hormone directly stimulates the cells in the growth plate, and does not support the theory that the increase in the plasma concentration of somatomedin that follows growth hormone administration is the cause of this stimulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Isaksson, O G -- Jansson, J O -- Gause, I A -- New York, N.Y. -- Science. 1982 Jun 11;216(4551):1237-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079756" target="_blank"〉PubMed〈/a〉

    Serial position curve in rats: role of the dorsal hippocampus (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-08
    Description: In an eight-arm radial maze, normal rats demonstrated good immediate retention for the order of first items (primacy component of serial position curve) and last items (recency component of serial position curve) of an eight-item (arm) list. In contrast, rats with dorsal hippocampal lesions displayed, on an immediate retention test, disruption of the primacy but not the recency component of the serial position curve. Furthermore, imposing a 10-minute delay before the retention test impaired all components of the serial position curve. These results support correspondence in mnemonic function of the hippocampus in animals and humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kesner, R P -- Novak, J M -- RR07092-12/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):173-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123228" target="_blank"〉PubMed〈/a〉

    Velocity signals related to hand movements recorded from red nucleus neurons in monkeys (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-27
    Description: Neural activity of the red nucleus was studied in monkeys trained to operate devices requiring shoulder, elbow, wrist, hand, or finger movements. Single cell activity was more closely related to movements of the hand and fingers than to movements of the other joints. Discharge consistently preceded movements by a constant time interval; duration of discharge was highly correlated with the duration of movement; and discharge rate was highly correlated with movement velocity. These data suggest a role for the rubrospinal pathway in the initiation and control of hand movements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kohlerman, N J -- Gibson, A R -- Houk, J C -- 5-R01-NS14703/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):857-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100930" target="_blank"〉PubMed〈/a〉

    Modulation of striatal dopaminergic function by local injection of 5'-N-ethylcarboxamide adenosine (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-01
    Description: Rats rotated to the left when 5'-N-ethylcarboxamide adenosine (NECA) was injected into the left caudate nucleus and apomorphine was administered subcutaneously. The combination of NECA and apomorphine was more potent than L-(phenylisopropyl)adenosine and apomorphine in eliciting rotation, suggesting the involvement of adenosine receptors of the Ra type. The response was reduced when 2',5'-dideoxyadenosine was injected along with NECA into the caudate nucleus or when theorphylline was given intraperitoneally. Higher doses of apomorphine elicited a self-mutilatory response after the injection of NECA into the caudate nucleus. These results suggest that adenosine may be involved in the modulation of dopaminergic function in the striatum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, R D -- Proudfit, H K -- Yeung, S M -- New York, N.Y. -- Science. 1982 Oct 1;218(4567):58-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123218" target="_blank"〉PubMed〈/a〉

    Description: Inosine peripherally administered to rats markedly suppressed spontaneous food intake and food intake induced by diazepam, muscimol, insulin, and food deprivation. The purines 2-deoxyguanosine and 2-deoxyinosine also suppressed food deprivation-induced feeding, whereas 7-methylinosine, which does not bind to the benzodiazepine binding site in vitro, had no effect on food intake when compared with controls. These results suggest that purines may represent endogenous substances that regulate food intake through interactions with the benzodiazepine receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levine, A S -- Morley, J E -- New York, N.Y. -- Science. 1982 Jul 2;217(4554):77-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7046046" target="_blank"〉PubMed〈/a〉

    Autocidal control of screwworms in North America (1982)

    Details
    Publication Date: 1982-01-22
    Description: The larva of the blowfly Cochliomyia hominivorax, also known as the screwworm, eats the living flesh of cattle and sheep and other warm-blooded animals. A program to eradicate the screwworm in the United States was initiated in the 1950's. The program was very effective until 1968, but severe screwworm outbreaks occurred in 1972 to 1976 and in 1978. Although the program has again been effective since 1979, the possibility of outbreaks recurring in the future has highlighted the need for a broader understanding of the pest. Studies of screwworm populations in the United Stated and Mexico indicate that much of the genetic diversity of this insect is distributed among sympatric non-interbreeding populations. A new approach may be required to retain the effectiveness of the control program and to prevent a serious outbreak from threatening the economic viability of the U.S. livestock industry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richardson, R H -- Ellison, J R -- Averhoff, W W -- New York, N.Y. -- Science. 1982 Jan 22;215(4531):361-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7199204" target="_blank"〉PubMed〈/a〉

    Benzodiazepine receptor-mediated experimental "anxiety" in primates (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: The ethyl ester of beta-carboline-3-carboxylic acid has a high affinity for benzodiazepine receptors in the brain. In the rhesus monkey this substance produces an acute behavioral syndrome characterized by dramatic elevations in heart rate, blood pressure, plasma cortisol, and catecholamines. The effects are blocked by benzodiazepines and the specific benzodiazepine receptor antagonist Ro 15-1788. The benzodiazepine receptor may consist of several subsites or functional domains that independently recognize agonist, antagonists, or "active" antagonists such as beta-carboline-3-carboxylic acid ethyl ester. These results suggest that the benzodiazepine receptor is involved in both the affective and physiological manifestations of anxiety, and that the administration of beta-carboxylic acid ethyl ester to monkeys may provide a reliable and reproducible animal model of human anxiety.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ninan, P T -- Insel, T M -- Cohen, R M -- Cook, J M -- Skolnick, P -- Paul, S M -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1332-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6293059" target="_blank"〉PubMed〈/a〉

    Hemispheric asymmetries in the behavioral and hormonal effects of sexually differentiating mammalian brain (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-22
    Description: Estrogen pellets were placed in either the right or left hypothalamus of newborn female rats so that only one side of this brain area was exposed to the postnatal masculinizing and defeminizing effects of the hormone. The effects of estrogen on gonadotropin secretion and reproductive behavior depended on both the region and the side of implantation. Exposure of the left hypothalamus to estrogen resulted in defeminized development. Exposure of the right hypothalamus to estrogen resulted in masculinized development. Thus the response of the developing hypothalamus to gonadal steroids may be asymmetric.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nordeen, E J -- Yahr, P -- New York, N.Y. -- Science. 1982 Oct 22;218(4570):391-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123240" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-07-16
    Description: The ability of antiserum against murine L1210 leukemia to remove residual leukemia cells from murine bone marrow was investigated. Leukemic marrow was treated in vitro with antiserum and complement and used to hematologically reconstitute mice that had been irradiated with doses lethal to bone marrow. Following infusion of treated leukemic marrow, normal marrow returned without evidence of leukemia. More than 90 percent of the animals have survived for 11 months without untoward effects, suggesting that the technique may be of use in the treatment of acute leukemia in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trigg, M E -- Poplack, D G -- New York, N.Y. -- Science. 1982 Jul 16;217(4556):259-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7046048" target="_blank"〉PubMed〈/a〉

    Influence of female hormonal state on rhesus sexual behavior varies with space for social interaction (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-23
    Description: The sexual behavior of rhesus monkeys in 15 male-female pairings was observed in both a large and a small area during the follicular and luteal phases of the female's cycle. Males ejaculated in all tests at the follicular phase of the female's cycle and in 53 percent of tests at the luteal phase. However, a significant decline in ejaculation during tests at the luteal phase occurred in the large, but not in the small area. Thus the degree to which the pair's sexual behavior was influenced by the female's hormonal state depended on the spatial conditions of the test.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wallen, K -- MH35835/MH/NIMH NIH HHS/ -- RR-00165/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 23;217(4557):375-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7201164" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-10-22
    Description: Intravenous administration of rabbit antiserum to ovine corticotropin-releasing factor (CRF) markedly reduced the CRF-induced rise of plasma adrenocorticotropic hormone (ACTH) in intact nonstressed adult male rats while blocking more than 75 percent of the ACTH release observed in rats exposed to ether stress. Furthermore, antiserum to CRF significantly lowered ACTH levels in adrenalectomized animals. These results suggest that endogenous CRF plays a physiological role in regulating ACTH secretion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rivier, C -- Rivier, J -- Vale, W -- AM18811/AM/NIADDK NIH HHS/ -- AM20917/AM/NIADDK NIH HHS/ -- AM26741/AM/NIADDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Oct 22;218(4570):377-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6289439" target="_blank"〉PubMed〈/a〉

    Hormonal regulation of gonadotropin receptors and steroidogenesis in cultured fetal rat tests (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-22
    Description: Gonadotropic activation of the adult rat testis in vitro and in vivo is followed by down-regulation of luteinizing hormone receptors and decreased androgen responses to subsequent hormonal stimulation. In contrast, treatment of cultured fetal testes with gonadotropins and dibutyryl adenosine 3',5'-monophosphate enhanced steroidogenic responsiveness and did not cause the luteinizing hormone-receptor loss and desensitization that is characteristic of the adult gonad. The analysis of gonadotropin receptors and action in cultured fetal testis cells facilitates developmental studies of gonadal function, and has revealed significant differences in the responses of fetal and adult Leydig cells to gonadotropic regulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, D W -- Dufau, M L -- Catt, K J -- 1F33-HD06192/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 22;218(4570):375-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6289438" target="_blank"〉PubMed〈/a〉

    Description: Mice infected with Trypanosoma rhodesiense were treatment concurrently with cis-diamminedichloroplatinum (II) (DDP), disulfiram, and hydration. Most of the mice (92.5 percent) were cured; inoculation of blood or suspensions of brain or heart from these animals did not produce disease in recipient mice. The dose of DDP needed to eliminate the trypanosomes, 3 milligrams per kilogram of body weight per day for 7 days, was lethally toxic unless the animals received disulfiram orally and subcutaneous injections of physiologic saline, which reduced the acute renal necrosis caused by DDP alone. Some mild to moderate reversible renal damage was noted upon pathologic examination of the treated mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wysor, M S -- Zwelling, L A -- Sanders, J E -- Grenan, M M -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):454-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7201165" target="_blank"〉PubMed〈/a〉

    Interference with dimethylhydrazine induction of colon tumors in mice by epsilon-aminocaproic acid (1982)

    Description: The antifibrinolytic agent epsilon-aminocaproic acid given in the drinking water to Swiss ICR/Ha mice significantly counteracted the appearance of colorectal tumors induced by 21 weekly infections of 1,2-dimethylhydrazine. The drug affected both the number and the location of the tumors and, in some animals, altogether prevented their appearance. The low concentrations of epsilon-aminocaproic acid in the plasma of four control mice given the agent labeled with carbon-14 for 3 days suggest that the effect may depend not on inhibition of plasminogen activator activity, but on interference with the binding of some substance to the strong lysine binding site of plasminogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corasanti, J G -- Hobika, G H -- Markus, G -- New York, N.Y. -- Science. 1982 May 28;216(4549):1020-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6805074" target="_blank"〉PubMed〈/a〉

In contrast, repetitive elicitation of startle-like responses by electrical stimulation of the reticular formation led only to sensitization. Since these different locations represent different points along the acoustic startle circuit, the data suggest that sensitization may be related to the motor side of reflex arcs, whereas habituation may be related to the sensory side.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, M -- Parisi, T -- Gendelman, D S -- Tischler, M -- Kehne, J H -- MH-00004/MH/NIMH NIH HHS/ -- MH-18949/MH/NIMH NIH HHS/ -- MH-25642/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 12;218(4573):688-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7134967" target="_blank"〉PubMed〈/a〉

The sexual dimorphism is striking in the splenium, the caudal or posterior portion of the corpus callosum. The female splenium is both more bulbous and larger than the male counterpart. Since peristriate, parietal, and superior temporal fibers course through the splenium, this finding could be related to possible gender differences in the degree of lateralization for visuospatial functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DeLacoste-Utamsing, C -- Holloway, R L -- New York, N.Y. -- Science. 1982 Jun 25;216(4553):1431-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089533" target="_blank"〉PubMed〈/a〉

    Rabbit hepatic progesterone 21-hydroxylase exhibits a bimodal distribution of activity (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-20
    Description: Progesterone 21-hydroxylase activity varies extensively among liver microsomes prepared from individual New Zealand White (NZW) rabbits. The 21-hydroxylase activities are distributed between two groupings that differ by more than tenfold in mean activity. Both male and female animals are represented in the two groupings. However, females exhibited the higher activity more frequently than males. The 21-hydroxylation of progesterone is catalyzed by one of the liver microsomal cytochrome P-450 isozymes, form 1, and these differences in activity are suggestive of differences in the occurrence of this isozyme among NZW rabbits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dieter, H H -- Muller-Eberhard, U -- Johnson, E F -- HD04445/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):741-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6808664" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)

    Publication Date: 1982-01-15
    Description: Autoradiograms prepared from adult rat brains demonstrate that nerve cells and neuropil in different brain regions selectively concentrate and retain intravenously administered triiodothyronine, by mechanisms susceptible to saturation with excess triiodothyronine. A neuroregulatory role for thyroid hormones, strongly supported by the observations, may account for their marked effects on behavior and the activity of the autonomic nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dratman, M B -- Futaesaku, Y -- Crutchfield, F L -- Berman, N -- Payne, B -- Sar, M -- Stumpf, W E -- HD03110/HD/NICHD NIH HHS/ -- MH29549/MH/NIMH NIH HHS/ -- NS09914/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 15;215(4530):309-12.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053582" target="_blank"〉PubMed〈/a〉

    Hypotensive effect of fasting: possible involvement of the sympathetic nervous system and endogenous opiates (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-20
    Description: Fasting lowers blood pressure to a greater extent in spontaneously hypertensive rats than in normotensive rats. While fasting reduced cardiac sympathetic activity to an equivalent extent in both groups of animals, only in the hypertensive rats did fasting elicit an opiate-mediated vasodepressor response that was independent of sympathetic withdrawal. Both sympathetic nervous system suppression and endogenous opiate activation, therefore, may contribute to the hypotensive effect of fasting in the spontaneously hypertensive rat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Einhorn, D -- Young, J B -- Landberg, L -- AM 20378/AM/NIADDK NIH HHS/ -- HL 24084/HL/NHLBI NIH HHS/ -- RR 76/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):727-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100917" target="_blank"〉PubMed〈/a〉

    Description: Rats subjected to unilateral ablation of the motor cortex and placed on a narrow beam displayed transient contralateral paresis. An immediate and enduring acceleration of recovery was produced by a single dose of d-amphetamine given 24 hours after injury. This effect was blocked by haloperidol or by restraining the animals for 8 hours beginning immediately after amphetamine administration. A single dose of haloperidol given 24 hours after injury markedly slowed recovery.

    Description: This case study of the Critical Care Unit at Tianjin's First Central Hospital, its physician-director, and one of its patients provides a portrait of how the policy of the four modernizations is being applied to the field of medicine in the People's Republic of China. On this unit of an urban hospital the "fourth modernization," science and technology, is systematically brought to bear on the problems of critically ill patients. The Chinese dualities and dilemmas that this "scaling the heights" policy entails are continually played out on the Critical Care Unit. An intricate balancing is involved between modern Western and traditional Chinese medicine, and between rural public health programs and primary and tertiary care services, within a medical morality framework that combines present-day political ideology with age-old ethical precepts. At this juncture the overall balance seems to be moving in the direction of modern, city-based, curative medicine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fox, R C -- Swazey, J P -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):700-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100911" target="_blank"〉PubMed〈/a〉

    Pituitary receptor site blockade by a gonadotropin-releasing hormone antagonist in vivo: mechanism of action (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-23
    Description: Administration of a potent gonadotropin-releasing hormone (GnRH) antagonist [Nac-L-Ala1,pCl-D-Phe2,D-Trp3,6]GnRH as a single subcutaneous injection to castrated adult male rats reduced, by more than 90 percent, both serum luteinizing hormone concentrations and specific pituitary GnRH receptor binding. This effect persisted for 24 hours. The dissociation rate of the antagonist from pituitary membrane homogenates was fourfold slower than the dissociation rate of a potent agonist. The prolonged in vivo inhibition of pituitary GnRH receptor binding and luteinizing hormone secretion by the GnRH antagonist may be mediated by the slower dissociation rate of the antagonist from its specific pituitary membrane receptor site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heber, D -- Dodson, R -- Swerdloff, R S -- Channabasavaiah, K -- Stewart, J M -- New York, N.Y. -- Science. 1982 Apr 23;216(4544):420-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6280278" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)

    Publication Date: 1982-08-06
    Description: The principles of the measurement in vivo of the oxidation-reduction state of intramitochrondrial pyridine nucleotides were used in establishing a multichannel fluorometer-reflectometer. This approach made possible the study of changes of mitochrondrial redox states in four different organs (brain, liver, kidney, and testis) of the same animal, as well as the monitoring of four different cortical areas of the same brain hemisphere. In the measurement of reduced nicotinamide adenine dinucleotide fluorescence, oximetric and movement artifacts are negligible, but blood volume changes and tissue absorption properties are a source of error. The corrected fluorescence is obtained by subtracting the reflectance from the fluorescence signed in 1:1 ratio., During graded hypoxia, the corrected fluorescence showed a gradual increase and was maximal during anoxia in all four organs tested.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mayevsky, A -- Chance, B -- NINDS 10939/DS/DS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 6;217(4559):537-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7201167" target="_blank"〉PubMed〈/a〉

    Description: Leukotriene D4 (2 c 10(-9) mole), injected into the left circumflex coronary artery of anesthetized sheep, produced profound coronary vasoconstriction and impaired regional ventricular wall motion. This cardiac effect was neither inhibited by prior treatment of the sheep with a cyclooxygenase inhibitor nor associated with thromboxane B2 release into the coronary sinus. Intravenous FPL 55712 completely abolished the coronary vasoconstriction of leukotriene D4, but a significant reduction of regional wall shortening persisted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michelassi, F -- Landa, L -- Hill, R D -- Lowenstein, E -- Watkins, W D -- Petkau, A J -- Zapol, W M -- HL23591/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):841-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6808665" target="_blank"〉PubMed〈/a〉

    Neonatal treatment with antiserum to prolactin lowers blood pressure in rats (1982)

    Publication Date: 1982-07-09
    Description: Prolactin administration reportedly increases blood pressure in rats and rabbits. To study the effects of prolactin deficiency on blood pressure, rats were given saline, normal rabbit serum, or rabbit antiserum to rat prolactin on postnatal days 2 to 5. Both males and females given antiserum had significantly lower blood pressure at 14 weeks than rats given saline or normal rabbit serum. Blood pressure differences between females given antiserum and females given saline disappeared during and following pregnancy. The antiserum also lowered the concentration of prolactin in plasma 49 percent in males and decreased the prolactin response to ether stress in both sexes. These results suggest that endogenous prolactin is involved in blood pressure regulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mills, D E -- Buckman, M T -- Peake, G T -- New York, N.Y. -- Science. 1982 Jul 9;217(4555):162-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089550" target="_blank"〉PubMed〈/a〉

    Familial renal cell carcinoma with a 3;11 chromosome translocation limited to tumor cells (1982)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1982-09-03
    Description: Cytogenic studies were performed on the direct chromosome preparations of the renal cell carcinoma cells and the cultured peripheral blood lymphocytes of a patient with familial renal cell carcinoma. The results revealed a specific, acquired translocations (3p;11p) present in the majority of metaphases of the tumor, indicating that the development of renal cell carcinoma is associated with a deletion in the proximal end of 3p. Renal cell carcinoma is thus the third example--the first two being retinoblastoma and Wilms' tumor--of a chromosomal deletion occurring germinally or somatically in association with a specific tumor. This finding adds further support to the existence of specific human cancer genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pathak, S -- Strong, L C -- Ferrell, R E -- Trindade, A -- CA 27925/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 3;217(4563):939-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112106" target="_blank"〉PubMed〈/a〉

    (+)-Amphetamine binding to rat hypothalamus: relation to anorexic potency for phenylethylamines (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-29
    Description: Saturable and stereospecific binding sites for (+)-[3H]amphetamine were demonstrated in membrane preparations from rat brain. The density of these binding sites varies among brain regions and is highest in the hypothalamus and brainstem. Specific (+)-[3H]amphetamine binding in hypothalamus is largely confined to synaptosomal membranes, rapidly reversible, and sensitive to both heat and proteolytic enzymes. Scatchard analysis of the equilibrium binding data revealed two distinct sites with apparent affinity constants of 93 and 300 nanomoles per liter, respectively. The effects of various psychotropic drugs as well as a number of putative neurotransmitters and related agonists and antagonists in displacing specific (+)-[3H]amphetamine binding demonstrate that these binding sites are not associated with any previously described neurotransmitter or drug receptors, but are specific for amphetamine and related phenylethylamine derivatives. Furthermore, the relative affinities of a series of phenylethylamine derivatives for (+)-[3H]amphetamine binding sites in hypothalamic membranes is highly correlated to their potencies as anorexic agents. These results suggest the presence of specific receptor sites in hypothalamus that mediate the anorexic activity of amphetamine and related drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paul, S M -- Hulihan-Giblin, B -- Skolnick, P -- New York, N.Y. -- Science. 1982 Oct 29;218(4571):487-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123250" target="_blank"〉PubMed〈/a〉

    Oxytocin, vasopressin, and estrogen-stimulated neurophysin: daily patterns of concentration in cerebrospinal fluid (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-06-25
    Description: The concentrations of oxytocin, arginine vasopressin, and estrogen stimulated neurophysin in cerebrospinal fluid of monkeys showed a daily fluctuation with high concentrations occurring during the light period. The patterns of oxytocin and estrogen-stimulated neurophysin in the cerebrospinal fluid were not observed in the plasma nor were they altered after the administration of a dose of estradiol that increased concentrations of estrogen-stimulated neurophysin in plasma. The disassociation between these cerebrospinal fluid and plasma patterns and values suggests that the secretory activity of neurons that release estrogen-stimulated neurophysin and oxytocin into the cerebrospinal fluid is controlled by mechanisms different from those that control their release into the plasma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perlow, M J -- Reppert, S M -- Artman, H A -- Fisher, D A -- Self, S M -- Robinson, A G -- New York, N.Y. -- Science. 1982 Jun 25;216(4553):1416-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7201163" target="_blank"〉PubMed〈/a〉

    Nonopiate effects of dynorphin and des-Tyr-dynorphin (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-10
    Description: Intracerebroventricular administration of dynorphin produced potent and long-lasting effects on motor function and the electroencephalogram in rats. In addition, local iontophoretic or pressure ejection of dynorphin consistently inhibited hippocampal unit activity. None of these effects were significantly affected by naloxone even at high doses. Moreover, a fragment of dynorphin that failed to displace any of a number of tritiated narcotics from rat brain homogenates produced similar effects on these physiological measures in vivo. On the basis of a variety of criteria for "opiate action," the results suggest that a second biologically active site within the dynorphin sequence is capable of quite potent but nonopiate effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walker, J M -- Moises, H C -- Coy, D H -- Baldrighi, G -- Akil, H -- 1F32DA04183/DA/NIDA NIH HHS/ -- DA02265/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1136-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6128791" target="_blank"〉PubMed〈/a〉

    The carboxy terminus of the precursor to vasopressin and neurophysin: immunocytochemistry in rat brain (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-27
    Description: A pituitary glycopeptide whose amino acid sequence was previously identified has now been recognized as the final portion of the precursor to arginine vasopressin and its associated neurophysin. Immunocytochemical techniques with antiserums against this 39 amino acid peptide and vasopressin were used to study their distribution in the rat central nervous system. The peptide is located in vasopressin-synthesizing cells in the neurosecretory magnocellular nuclei. Positively stained fibers project from the magnocellular nuclei through the median eminence to the posterior pituitary. Studies of the homozygous Brattleboro rat, which is known to be deficient in the production of vasopressin and its related neurophysin, also show the absence of immunoreactivity to this peptide. These immunocytochemical data strongly indicate that the peptide is synthesized with vasopressin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, S J -- Seidah, N G -- Chretien, M -- DA00154/DA/NIDA NIH HHS/ -- DA02265/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):853-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6125034" target="_blank"〉PubMed〈/a〉

    Dynorphin and vasopressin: common localization in magnocellular neurons (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-02
    Description: The opioid peptide dynorphin is widely distributed in neuronal tissue of rats. By immunocytochemical methods, it was shown previously that dynorphin-like immunoreactivity is present in the posterior pituitary and the cells of the hypothalamic neurosecretory magnocellular nuclei which also are responsible for the synthesis of oxytocin, vasopressin, and their neurophysins. By using an affinity-purified antiserum to the non-enkephalin part of the dynorphin molecule it has now been demonstrated that dynorphin and vasopressin occur in the same hypothalamic cells of rats, whereas dynorphin and oxytocin occur in separate cells. Homozygous Brattleboro rats (deficient in vasopressin) have magnocellular neurons that contain dynorphin separate from oxytocin. Thus dynorphin and vasopressin, although they occur in the same cells, appear to be under separate genetic control and presumably arise from different precursors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, S J -- Akil, H -- Fischli, W -- Goldstein, A -- Zimmerman, E -- Nilaver, G -- van wimersma Griedanus, T B -- DA 00254/DA/NIDA NIH HHS/ -- DA 02265/DA/NIDA NIH HHS/ -- DA1199/DA/NIDA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Apr 2;216(4541):85-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6121376" target="_blank"〉PubMed〈/a〉

    Lesion-induced sprouting in the rat dentate gyrus is inhibited by repeated ethanol administration (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-19
    Description: The effect of ethanol on hippocampal axonal sprouting was studied with a histochemical technique for identifying acetylcholinesterase. Unilateral lesion of the entorhinal cortex in adult rats produced an increase in the density of acetylcholinesterase staining in the outer molecular layer and a concomitant increase in the width of the pale-staining commissural-associational zone of the dentate gyrus. Other rats were given ethanol (11.3 +/- 0.45 grams per kilogram) for 2 weeks before and 9 days after receiving the lesion. Ethanol abolished the expansion of the commissural-associated zone. The effect of ethanol on sprouting axons suggests that it may inhibit recovery of function after brain injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, J R -- Lind, M D -- Demuth, R M -- Parker, E S -- Alkana, R L -- Cassell, M -- Black, A C Jr -- AA-03884/AA/NIAAA NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 19;218(4574):809-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7134977" target="_blank"〉PubMed〈/a〉

    Description: Maximum expiratory flow rate at 30 percent of vital capacity above residual volume served as an index of airway obstruction in comparing the effects of leukotriene C and histamine administered by aerosol to five normal persons. Leukotriene C was 600 to 9500 times more potent than histamine on a molar basis in producing an equivalent decrement in the residual volume. The leukotriene C response was slow in onset and prolonged, reminiscent of the effects of aerosol allergen challenge in asthmatic allergic subjects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weiss, J W -- Drazen, J M -- Coles, N -- McFadden, E R Jr -- Weller, P F -- Corey, E J -- Lewis, R A -- Austen, K F -- AI-00399/AI/NIAID NIH HHS/ -- AI-07722/AI/NIAID NIH HHS/ -- AI-10356/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 9;216(4542):196-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063880" target="_blank"〉PubMed〈/a〉

    Central regulation of intestinal motility by somatostatin and cholecystokinin octapeptide (1982)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1982-06-25
    Description: When injected continuously into the lateral ventricles of the rat, somatostatin increased the frequency of the migrating myoelectric complexes of the small intestine in a dose-related manner. A significant increase was obtained at a dose as low as 0.066 picomole per minute. In contrast, cholecystokinin octapeptide decreased the frequency of the migrating myoelectric complex of the small intestine or disrupted this pattern when injected into the lateral ventricle at rates of 0.073 to 0.23 picomole per minute. These findings support the hypothesis that somatostatin and cholecystokinin octapeptide act on central nervous system structures that are involved in the control of intestinal motility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bueno, L -- Ferre, J P -- New York, N.Y. -- Science. 1982 Jun 25;216(4553):1427-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6124037" target="_blank"〉PubMed〈/a〉

These results show for the first time that neuropeptides in the brainstem may modulate posture and movement, and they suggest that some forms of movement disorder such as dystonia may be due to a disordered regulation of postural and locomotor mechanisms by adrenocorticotropin 1-24.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacquet, Y F -- Abrams, G M -- K07 00478/PHS HHS/ -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):175-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6289433" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-02-26
    Description: The glucagon analog [l-N alpha-trinitrophenylhistidine, 12-homoarginine]-glucagon (THG) was examined for its ability to lower blood glucose concentrations in rats made diabetic with streptozotocin. In vitro, THG is a potent antagonist of glucagon activation of the hepatic adenylate cyclase assay system. Intravenous bolus injections of THG caused rapid decreases (20 to 35 percent) of short duration in blood glucose. Continuous infusion of low concentrations of the inhibitor led to larger sustained decreases in blood glucose (30 to 65 percent). These studies demonstrate that a glucagon receptor antagonist can substantially reduce blood glucose levels in diabetic animals without addition of exogenous insulin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, D G -- Goebel, C U -- Hruby, V J -- Bregman, M D -- Trivedi, D -- AM21085/AM/NIADDK NIH HHS/ -- AM25318/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 26;215(4536):1115-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6278587" target="_blank"〉PubMed〈/a〉

In animals with lesions desipramine failed to reduce the density of beta-adrenoceptors but decreased the response of adenosine 3',5'-monophosphate to isoproterenol and norepinephrine to the same degree as in animals without lesions. The results demonstrate a functional linkage between serotonergic and noradrenergic systems in the rat cortex, with beta-adrenergic receptors and neurohormonal sensitivity of the adenosine 3',5'-monophosphate-generating system being under separate regulatory control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janowsky, A -- Okada, F -- Manier, D H -- Applegate, C D -- Sulser, F -- Steranka, L R -- New York, N.Y. -- Science. 1982 Nov 26;218(4575):900-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6291152" target="_blank"〉PubMed〈/a〉

The B10A (H-2a) strain of mice has significantly higher glucocorticoid receptor levels and a significantly greater biochemical response to glucocorticoid than the B10 (H-2b) strain, which differs from B10A within the H-2 complex only. Thus, the anti-inflammatory hormone response of glucocorticoids is correlated to hormone receptor level, both of which are influenced by the H-2 locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gupta, C -- Goldman, A -- DE-0541/DE/NIDCR NIH HHS/ -- DE-4622/DE/NIDCR NIH HHS/ -- DE-5592/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1982 May 28;216(4549):994-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079749" target="_blank"〉PubMed〈/a〉

    Coronary vascular reactivity after acute myocardial ischemia (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-05
    Description: Exogenous thrombin produced a biphasic response (a potent dose-related vasodilatation followed by vasoconstriction) in nonischemic canine coronary arteries. The vasodilatation was not blocked by propranolol, atropine, or indomethacin, but was completely blocked by heparin or denudation of the intimal endothelial cells. A similar loss of vasodilating response to thrombin occurred in ischemic coronary arteries with a concomitant enhancement of vasoconstriction. This study indicates that altered responses to thrombin in coronary arteries with damaged endothelium may play an important role in the pathogenesis of coronary vasospasm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ku, D D -- HL-24485/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 5;218(4572):576-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123259" target="_blank"〉PubMed〈/a〉

    Brain target sites for 1,25-dihydroxyvitamin D3 (1982)

    Details
    Publication Date: 1982-03-12
    Description: Autoradiographic studies with 3H-labeled 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] demonstrate, in certain neurons of rat forebrain, hindbrain, and spinal cord, a nuclear retention and concentration of radioactivity, which can be prevented by treatment with 1,25(OH)2D3, but not with 25-hydroxyvitamin D3. These results indicate the presence of brain receptors in addition to pituitary receptors for 1,25(OH)2D3 and suggest a central modulation of calcium homeostasis and other central effects for this hormone. The existence of a brain-pituitary axis for certain 1,25(OH)2D3-mediated endocrine-autonomic effects is postulated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stumpf, W E -- Sar, M -- Clark, S A -- DeLuca, H F -- AM14881/AM/NIADDK NIH HHS/ -- NS09912/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 12;215(4538):1403-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6977846" target="_blank"〉PubMed〈/a〉

    Transposition of cloned P elements into Drosophila germ line chromosomes (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-22
    Description: Recombinant DNA carrying the 3-kilobase transposable element was injected into Drosophila embryos of a strain that lacked such elements. Under optimum conditions, half of the surviving embryos showed evidence of P element-induced mutations in a fraction of their progeny. Direct analysis of the DNA of strains derived from such flies showed them to contain from one to five intact 3-kilobase P elements located at a wide variety of chromosomal sites. DNA sequences located outside the P element on the injected DNA were not transferred. Thus P elements can efficiently and selectively transpose from extrachromosomal DNA to the DNA of germ line chromosomes in Drosophila embryos. These observations provide the basis for efficient DNA-mediated gene transfer in Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spradling, A C -- Rubin, G M -- New York, N.Y. -- Science. 1982 Oct 22;218(4570):341-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6289435" target="_blank"〉PubMed〈/a〉

    Controlled drinking by alcoholics? New findings and a reevaluation of a major affirmative study (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-09
    Description: Controlled drinking has recently become a controversial alternative to abstinence as an appropriate treatment goal for alcoholics. In this study we reexamine the evidence underlying a widely cited report by Sobell and Sobell of successful controlled drinking by a substantial proportion of gamma (physically dependent) alcoholic subjects in a behavior therapy experiment. A review of the evidence, including official records and new interviews, reveals that most subjects trained to do controlled drinking failed from the outset to drink safely. The majority were rehospitalized for alcoholism treatment within a year after their discharge from the research project. A 10-year follow-up (extended through 1981) of the original 20 experimental subjects shows that only one, who apparently had not experienced physical withdrawal symptoms, maintained a pattern of controlled drinking; eight continued to drink excessively--regularly or intermittently--despite repeated damaging consequences; six abandoned their efforts to engage in controlled drinking and became abstinent; four died from alcohol-related causes; and one, certified about a year after discharge from the research project as gravely disabled because of drinking, was missing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pendery, M L -- Maltzman, I M -- West, L J -- New York, N.Y. -- Science. 1982 Jul 9;217(4555):169-75.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089552" target="_blank"〉PubMed〈/a〉

    Intraneuronal aluminum accumulation in amyotrophic lateral sclerosis and Parkinsonism-dementia of Guam (1982)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1982-09-10
    Description: Scanning electron microscopy with energy-dispersive x-ray spectrometry was used to analyze the elemental content of neurofibrillary tangle (NFT)-bearing and NFT-free neurons within the Sommer's sector (H1 region) of the hippocampus in Guamanian Chamorros with amyotrophic lateral sclerosis and parkinsonism-dementia and in neurologically normal controls. Preliminary data indicate prominent accumulation of aluminum within the nuclear region and perikaryal cytoplasm of NFT-bearing hippocampal neurons, regardless of the underlying neurological diagnosis. These findings further extend the association between intraneuronal aluminum and NFT formation and support the hypothesis that environmental factors are related to the neurodegenerative changes seen in the Chamorro population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perl, D P -- Gajdusek, D C -- Garruto, R M -- Yanagihara, R T -- Gibbs, C J -- AG-01415/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 10;217(4564):1053-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112111" target="_blank"〉PubMed〈/a〉

    Description: Platelet-activating factor caused rapid pulmonary vasoconstriction and edema in isolated lungs perfused with albumin-free salt solution devoid of formed blood elements. These effects may be due in part to the action of leukotrienes D4 and C4, which were identified by bioassay and high-pressure liquid chromatography in the lung effluent after stimulation by platelet-activating factor. These findings help illuminate some of the deleterious effects that platelet-activating factor elicits in anaphylactic reactions and possibly in other forms of lung injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Voelkel, N F -- Worthen, S -- Reeves, J T -- Henson, P M -- Murphy, R C -- HL 14985/HL/NHLBI NIH HHS/ -- HL 25857/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 15;218(4569):286-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123233" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-30
    Description: The nonhallucinogenic ergot derivative lisuride exerts many pharmacological effects that are similar to those of its hallucinogenic congener, lysergic acid diethylamide (LSD). Animals trained to discriminate between the presence of one drug and the other can be used to differentiate the actions of these compounds on a neuronal level. The discriminative stimulus effect of LSD (the LSD cue) is similar to that of the serotonin agonist quipazine, whereas the lisuride cue is similar to that of the dopamine agonist apomorphine. These data support the hypothesis that serotonin is intricately involved in the hallucinogenic effects of LSD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, F J -- Appel, J B -- 9RO1 DA 02543/DA/NIDA NIH HHS/ -- R01 MH 243593/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 30;216(4545):535-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7071600" target="_blank"〉PubMed〈/a〉

    Description: We have examined a pair of eyes from a normal, full-term infant who died at 8 days as a result of accidental injury. Eyes were obtained immediately after death, fixed, and sectioned for light microscopy. Results from both eyes were substantially the same. The macular region was still drastically immature at 1 week. Even though a foveal depression existed, all cell layers were still present across it. Furthermore, the inner nuclear layer was divided into two separate layers. The receptor layer was reduced to one or two cells thick; receptors had both inner and outer segments, but they were very short and stumpy. The region of immaturity covered about 5 degrees of the retina. These findings suggest that the central region of a human infant's retina is probably not fully functional at birth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abramov, I -- Gordon, J -- Hendrickson, A -- Hainline, L -- Dobson, V -- LaBossiere, E -- EY01208/EY/NEI NIH HHS/ -- EY01523/EY/NEI NIH HHS/ -- EY01697/EY/NEI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Jul 16;217(4556):265-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178160" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-03-12
    Description: Intracellular recordings in vivo from noradrenergic neurons in the rat locus coeruleus showed that membrane potential was hyperpolarized by the administration of clonidine (an alpha 2-adrenoceptor agonist) or after a burst of spikes evoked by intracellular pulses; both types of hyperpolarization were associated with a decrease in membrane input resistance, and both could be blocked by the alpha 2-adrenoceptor antagonist piperoxane. These results suggest that a hyperpolarization of membrane potential mediated by an alpha 2-adrenoceptor underlies both clonidine- and activation-induced inhibition of locus coeruleus cell firing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aghajanian, G K -- VanderMaelen, C P -- MH-14276/MH/NIMH NIH HHS/ -- MH-14459/MH/NIMH NIH HHS/ -- MH-17871/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 12;215(4538):1394-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6278591" target="_blank"〉PubMed〈/a〉

    Description: Extrathyroidal tissues of man and the rat contain a potent inhibitor of the binding of thyroid hormones to serum proteins and to an anion-exchange resin. The inhibitor is heat-labile and nondialyzable. It acts by reducing the binding affinity of thyroid hormones to serum proteins, not by reducing the number of binding sites. The tissue inhibitor is similar in several characteristics to an inhibitor described previously in the serum of some critically ill patients, suggesting that the tissue inhibitor may leak into the circulation in severe illnesses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chopra, I J -- Solomon, D H -- Teco, G N -- Eisenberg, J B -- AM 16155/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 22;215(4531):407-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058324" target="_blank"〉PubMed〈/a〉

    Bleb formation in hepatocytes during drug metabolism is caused by disturbances in thiol and calcium ion homeostasis (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-09-24
    Description: A wide variety of toxic chemicals cause blebbing of the plasma membrane in isolated hepatocytes. These alterations in surface structure occur well before cell death. The formation of blebs appears to be directly related to changes in the concentration of extramitochondrial calcium ions. These changes probably reduce the ability of the hepatocyte cytoskeleton to maintain normal surface morphology. The concentration of soluble thiols, notably glutathione, appears to regulate the size of the extramitochondrial calcium ion pool. Disturbances in intracellular thiol and calcium ion homeostasis therefore seem to be responsible for the surface blebbing observed during toxic injury to isolated hepatocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jewell, S A -- Bellomo, G -- Thor, H -- Orrenius, S -- Smith, M -- New York, N.Y. -- Science. 1982 Sep 24;217(4566):1257-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112127" target="_blank"〉PubMed〈/a〉

An examination of this hypothesis reveals that the liver mitochondria of ethanol-fed rats show a dissociation between the respiratory functions and the lipid composition and microviscosity of the membranes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gordon, E R -- Rochman, J -- Arai, M -- Lieber, C S -- New York, N.Y. -- Science. 1982 Jun 18;216(4552):1319-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079764" target="_blank"〉PubMed〈/a〉

    Prenatal exposure to the herbicide 2,4-dichlorophenyl-p-nitrophenyl ether destroys the rodent Harderian gland (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-15
    Description: Exposure of mice to the herbicide 2,4-dichlorophenyl-p-nitrophenyl ether during gestation produces abnormalities that are not readily apparent at birth but become obvious as the pups mature. By 2 weeks after birth there are severe intraorbital defects resulting from destruction of the Harderian glands behind the eyes. This effect is noticeable only postnatally because the Harderian gland does not grow or function until after birth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, L E Jr -- Kavlock, R J -- Chernoff, N -- Ferrell, J -- McLamb, J -- Ostby, J -- New York, N.Y. -- Science. 1982 Jan 15;215(4530):293-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053576" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-05-07
    Description: Exposure of rats to phenobarbital during late prenatal development decreased the concentration of testosterone in plasma and the brain during the late fetal, early postnatal, pubertal, and adult periods, By decreasing the production of testosterone in the brain during the period of sexual differentiation, phenobarbital may lead to sexual dysfunction in later life.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gupta, C -- Yaffe, S J -- Shapiro, B H -- GM-26222/GM/NIGMS NIH HHS/ -- HD -10063/HD/NICHD NIH HHS/ -- T-32GM07514/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 May 7;216(4546):640-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7200262" target="_blank"〉PubMed〈/a〉

    Sex and handedness differences in cerebral blood flow during rest and cognitive activity (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-13
    Description: Cognitive activity resulted in increased flow of blood to the cerebral hemispheres. The increase was greater to the left hemisphere for a verbal task and greater to the right hemisphere for a spatial task. The direction and degree of hemispheric flow asymmetry were influenced by sex and handedness, females having a higher rate of blood flow per unit weight of brain, and females and left-handers having a greater percentage of fast-clearing tissue, presumably gray matter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gur, R C -- Gur, R E -- Obrist, W D -- Hungerbuhler, J P -- Younkin, D -- Rosen, A D -- Skolnick, B E -- Reivich, M -- MH 30456/MH/NIMH NIH HHS/ -- NS-10939-09/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 13;217(4560):659-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089587" target="_blank"〉PubMed〈/a〉

    Presynaptic location and axonal transport of beta 1-adrenoreceptors in the rat brain (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-06
    Description: Interruption of the ascending noradrenergic neurons of the locus coeruleus in the rat forebrain with 6-hydroxydopamine produced a progressive accumulation, proximal to the lesion, of tritiated dihydroalprenolol binding activity over 2 days. This accumulation could be blocked by interrupting the neurons closer to their cell bodies. Competitive binding studies with the beta 2 agonist Zinterol suggested that the accumulated beta-receptors were primarily of the beta 1 subtype. These results suggest that, in the rat brain, some beta 1-adrenoreceptors are located in presynaptic, noradrenergic locus coeruleus neurons and are transported in their axons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levin, B E -- New York, N.Y. -- Science. 1982 Aug 6;217(4559):555-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178165" target="_blank"〉PubMed〈/a〉

    Adrenal medullary enkephalin-like peptides may mediate opioid stress analgesia (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-06
    Description: Different patterns of fact shock activate opioid and nonopioid mechanisms of stress analgesia in the rat. Opioid, but not nonopioid, stress analgesia is reduced by adrenal demedullation and denervation and is potentiated by reserpine, a drug known to increase concentrations of adrenal medullary enkephalin-like peptides. It is suggested that adrenal enkephalins mediate opioid stress analgesia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lewis, J W -- Tordoff, M G -- Sherman, J E -- Liebeskind, J C -- NS07628/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 6;217(4559):557-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089582" target="_blank"〉PubMed〈/a〉

    Reduced sympathetic nervous system responsivity associated with the relaxation response (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-08
    Description: Sympathetic nervous system activity was assessed in experimental and control subjects who were exposed to graded orthostatic and isometric stress during monthly hospital visits. After the first session, the experimental subjects practiced a technique that elicited the relaxation response. Their concentrations of plasma norepinephrine during subsequent graded stresses were significantly higher. No such changes were noted in the control group. These results were than replicated in the control group in a crossover experiment. The groups did not differ in their heart rate and blood pressure responses. These observations are consistent with reduced norepinephrine end-organ responsivity after regular elicitation of the relaxation response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffman, J W -- Benson, H -- Arns, P A -- Stainbrook, G L -- Landsberg, G L -- Young, J B -- Gill, A -- HL-07374/HL/NHLBI NIH HHS/ -- HL-22727/HL/NHLBI NIH HHS/ -- HL-24084/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):190-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7031901" target="_blank"〉PubMed〈/a〉
