    Ontogeny of gastric acid secretion in the rat: evidence for multiple response systems (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-02
    Description: Gastric acid secretion has been thought to depend on histamine stimulation of the parietal cell. However, in the 2-week-old rat neither exogenous histamine nor the H-2 receptor agonist impromidine stimulates acid secretion, whereas pentagastrin and the cholinergic agent bethanechol are potent stimuli. At this age, the effect of pentagastrin in acid secretion is not blocked by the H-2 receptor antagonist cimetidine, nor is it potentiated by impromidine. These data suggest that, in the rat pup, the acid secretory response to pentagastrin and cholinergic agents occurs before the histamine-mediated system is functional and operates independently of the actions of histamine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ackerman, S H -- K1-MH00077/MH/NIMH NIH HHS/ -- R01-AM-18804/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 2;217(4554):75-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6211765" target="_blank"〉PubMed〈/a〉

    Micromolar affinity benzodiazepine receptors: identification and characterization in central nervous system (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-06-11
    Description: Receptors that selectively bind micromolar concentrations of benzodiazepines are present in rat brain membrane. These micromolar receptors exhibit saturable, stereospecific binding, and the potency of benzodiazepine binding to these receptors is correlated with the ability of the benzodiazepines to inhibit maximum electric shock-induced convulsions. Benzodiazepine receptors with nanomolar affinity differ from the micromolar receptors in their binding, kinetic, and pharmacologic characteristics. The micromolar receptors also bind phenytoin, a non-benzodiazepine anticonvulsant. These results provide evidence for a distinct class of clinically relevant benzodiazepine receptors that may regulate neuronal excitability and anticonvulsant activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowling, A C -- DeLorenzo, R J -- NS 1352/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jun 11;216(4551):1247-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6281893" 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〉

    Reversal of morphine disruption of maternal behavior by concurrent treatment with the opiate antagonist naloxone (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-08
    Description: Rats whose pregnancies were surgically terminated on day 17 of gestation were injected with morphine, morphine plus naloxone hydrochloride, or saline, and then tested for maternal responsiveness toward foster young. Morphine treatment alone significantly disrupted the rate of onset and quality of maternal responsiveness. Concurrent administration of naloxone to morphine-injected rats reinstated the rapid onset of behavioral responsiveness toward foster young, such that the responsiveness of the rats treated with both morphine and naloxone was indistinguishable from that shown by saline-injected controls. The disruptive effects of morphine did not appear to result from a general reduction in activity levels as measured in an open-field apparatus. These findings suggest that the normal onset and maintenance of maternal behavior in the rat may be regulated by endogenous opiates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bridges, R S -- Grimm, C T -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):166-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123227" target="_blank"〉PubMed〈/a〉

    Long-term synaptic potentiation in the superior cervical ganglion (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-03-12
    Description: Brief tetanic stimulation of the preganglionic nerves to the superior cervical ganglion enhances the postganglionic response to single preganglionic stimuli for 1 to 3 hours. This long-term potentiation of transmission through the ganglion is apparently not attributable to a persistent muscarinic action of the preganglionic neurotransmitter, acetylcholine, since neither the magnitude nor the time course of the phenomenon is reduced by atropine. The decay of long-term potentiation can be described by a first-order kinetic process with a mean time constant of 80 minutes. We conclude that long-term potentiation, once considered a unique property of the hippocampus, is in fact a more general feature of synaptic function. This form of synaptic memory may significantly influence information processing and control in other regions of the nervous system, including autonomic ganglia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, T H -- McAfee, D A -- 12116/PHS HHS/ -- NS 16576/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 12;215(4538):1411-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6278593" 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〉

    High angiotensin-converting enzyme activity in the neurohypophysis of Brattleboro rats (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-07
    Description: The activity of angiotensin-converting enzyme is significantly higher in the intermediate and posterior pituitary lobes of Brattleboro rats than in Long-Evans control rats. The high activity level was reversed by vasopressin treatment. Conversely, angiotensin-converting enzyme activity was significantly lower in the anterior pituitary of Brattleboro rats than in Long-Evans rats, and this activity level was not affected by vasopressin. these findings suggest an inverse relation between vasopressin and angiotensin systems in the posterior and intermediate lobes of the pituitary gland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chevillard, C -- Saavedra, J M -- New York, N.Y. -- Science. 1982 May 7;216(4546):646-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6280284" 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〉

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〉

The B cells were obtained from the thymus of a patient with myasthenia gravis. The antibody produced by the cell line precipitated acetylcholine receptors from denervated and innervated rat muscle and from human muscle, but did not show detectable response to the acetylcholine receptors from the electric organs of Narke japonica. The monoclonal antibody showed identical binding patterns in innervated and denervated rat muscles. Passive transfer of the monoclonal antibody into rats induced moderate muscle weakness and electromyographic changes characteristic of myasthenia gravis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kamo, I -- Furukawa, S -- Tada, A -- Mano, Y -- Iwasaki, Y -- Furuse, T -- Ito, N -- Hayashi, K -- Satoyoshi, E -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):995-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6297000" 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)

    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〉

    alpha A-crystallin messenger RNA of the mouse lens: more noncoding than coding sequences (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-19
    Description: The 14S messenger RNA (1300 to 1500 nucleotides) for the alpha A chain of alpha-crystallin of the mammalian lens is nearly three times larger than required to code for the polypeptide that contains 173 amino acids. As a means of accounting for this anomaly, a complementary DNA clone for the mouse alpha A-crystallin messenger RNA was constructed in pBR322 and sequenced. Derivation of the protein sequence from the nucleic acid sequence showed that mouse alpha A-crystallin is similar to that of other organisms. The messenger RNA contains 536 nucleotides located on the 3' side of the coding region, excluding the polyadenylate stretch. This 3' sequence does not encode any other crystallin and has multiple termination codons in the three possible reading frames.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, C R -- Shinohara, T -- Piatigorsky, J -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):985-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7156978" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-07-02
    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〉

    Description: Cyclic adenosine monophosphate (AMP) analogs or agents that increase intracellular cyclic AMP rapidly stimulate transcription of the prolactin gene in a line of cultured rat pituitary cells. This effect is correlated with the phosphorylation of a chromatin-associated basic protein designated BPR.

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-06-25
    Description: Avian myeloblastosis virus is defective in reproductive capacity, requiring a helper virus to provide the viral proteins essential for synthesis of new infectious virus. This virus arose by recombination of the nondefective helper virus and host cellular sequences present within the normal avian genome. These latter sequences are essential for leukemogenic activity. The complete nucleotide sequence of this region is reported. Within the acquired cellular sequences there is an open reading frame of 795 nucleotides starting with the initiation codon ATG (adenine, thymine, guanine) and terminating with the triplet TAG. This open reading frame could code for the putative transforming protein of 265 amino acids with a molecular weight of approximately 30,000.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rushlow, K E -- Lautenberger, J A -- Papas, T S -- Baluda, M A -- Perbal, B -- Chirikjian, J G -- Reddy, E P -- New York, N.Y. -- Science. 1982 Jun 25;216(4553):1421-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6283631" target="_blank"〉PubMed〈/a〉

    Description: The integrity of the suprachiasmatic nuclei (SCN) of the hypothalamus is essential to the expression of normal circadian rhythms in rodents. Electrical stimulation of the SCN caused phase shifts and period changes in the freerunning feeding rhythms of rats and activity rhythms of hamsters. The phase response curve for SCN stimulation appears to parallel that for light pulses. These findings strengthen the hypothesis derived from lesion studies that the SCN are the dominant light-entrained oscillators in the rodent circadian system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rusak, B -- Groos, G -- New York, N.Y. -- Science. 1982 Mar 12;215(4538):1407-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063851" target="_blank"〉PubMed〈/a〉

    Description: A synthetic antagonist of luteinizing hormone-releasing hormone blocked ovulation in rats in a dose-dependent manner when given by gavage on the afternoon of proestrus. Ovulation was delayed for at least 1 day in all animals given 2 milligrams of antogonist and in some of the animals treated with 1 or 0.5 milligram. Oral administration of 2 milligrams also blocked the preovulatory surge of luteinizing hormone. This demonstration that antagonists of luteinizing hormone-releasing hormone can have oral antiovulatory activity clearly enhances their therapeutic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nekola, M B -- Horvath, A -- Ge, L J -- Coy, D H -- Schally, A V -- HD-0-2831/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):160-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6750790" target="_blank"〉PubMed〈/a〉

    General anesthetics hyperpolarize neurons in the vertebrate central nervous system (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-09-10
    Description: The effect of general anesthetics on frog motoneurons and rat hippocampus pyramidal cells was examined with sucrose gap and intracellular recording, respectively. A number of volatile and intravenous anesthetics directly hyperpolarized the motoneurons. The potency of these agents in hyperpolarizing motoneurons was strongly correlated with their anesthetic potency. While the responses to barbiturates and alpha-chloralose were blocked by gamma-aminobutyric acid antagonists and were dependent on the chloride gradient, the responses to all the other anesthetics tested were generated by a separate mechanism. Intracellular recording from hippocampal pyramidal cells suggested that an increase in potassium conductance accounts for these responses. Such a nonsynaptic action would contribute to the decreased neuronal responsiveness observed for these compounds and thus to their anesthetic action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicoll, R A -- Madison, D V -- New York, N.Y. -- Science. 1982 Sep 10;217(4564):1055-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112112" target="_blank"〉PubMed〈/a〉

    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〉

    Oxytocin induces maternal behavior in virgin female rats (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-07
    Description: Intracerebroventricular administration of oxytocin to virgin female rats that had been ovariectomized and primed with estrogen 48 hours previously induced a rapid onset of full maternal behavior. The maternal behavior persisted and its incidence was dose-related. Tocinoic acid, the ring structure of oxytocin, also rapidly induced the onset of persistent, full maternal behavior. Arginine vasopressin induced persistent maternal behavior, but this behavior had a later onset. Prostaglandin F2 alpha induced strong partial maternal behavior, which showed early onset but did not persist. Many other peptides, ovarian steroids, and prostaglandin E2 were no more effective than saline. These findings suggest that the release of oxytocin and prostaglandin F2 alpha during labor may promote maternal behavior in rats.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pedersen, C A -- Ascher, J A -- Monroe, Y L -- Prange, A J Jr -- MH-22536/MH/NIMH NIH HHS/ -- MH-32316/MH/NIMH NIH HHS/ -- MH-34933/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 May 7;216(4546):648-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7071605" target="_blank"〉PubMed〈/a〉

    Transformation induced by Abelson murine leukemia virus involves production of a polypeptide growth factor (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-21
    Description: Rat embryo fibroblasts transformed by Abelson murine leukemia virus (MuLV) produce and release a transforming growth factor (TGF). Production of this factor is correlated with a tyrosine-specific protein kinase that is functionally active and is associated with the major Abelson MuLV gene product, P120. Transformation-defective mutants of Abelson MuLV do not transform cells, do not have their virus coded transforming gene product phosphorylated in tyrosine, and do not induce TGF production. Abelson MuLV-induced TGF morphologically transforms cells in culture, competes with 125I-labeled epidermal growth factor (EGF) for binding to cell receptors, and induces phosphorylation of tyrosine acceptor sites in the 160,000-dalton EGF membrane receptor.

    Inhibition of adrenocorticotropic hormone secretion in the rat by immunoneutralization of corticotropin-releasing factor (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    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〉

    In vivo identification of the transforming gene product of simian sarcoma virus (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-10
    Description: Simian sarcoma virus (SSV) deletion mutants were constructed from a molecular clone containing the entire infectious provirus. Transfection analysis of these mutants localized the SSV transforming gene to a small region of the viral genome encompassing its cell-derived sequence (v-sis). Antiserum to a peptide synthesized on the basis of the predicted amino acid sequence of the SSV transforming gene detected a 28,000-dalton protein that was specifically expressed in SSV transformed cells and that corresponded in size to that predicted from the v-sis coding sequence. The v-sis gene product designated p28sis was not a phosphoprotein, nor did it possess detectable protein kinase activity. These findings distinguish p28sis from a number of other retroviral onc proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robbins, K C -- Devare, S G -- Reddy, E P -- Aaronson, S A -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1131-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6293053" target="_blank"〉PubMed〈/a〉

    Quantitative autoradiographic mapping of herpes simplex virus encephalitis with a radiolabeled antiviral drug (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-09-17
    Description: 2'-Fluoro-5-methyl-l-beta-D-arabinosyluracil (FMAU) labeled with carbon-14 was used to image herpes simplex virus type 1-infected regions of rat brain by quantitative autoradiography. FMAU is a potent antiviral pyrimidine nucleoside which is selectively phosphorylated by virus-coded thymidine kinase. When the labeled FMAU was administered 6 hours before the rats were killed, the selective uptake and concentration of the drug and its metabolites by infected cells (defined by immunoperoxidase staining of viral antigens) allowed quantitative definition and mapping of HSV-1-infected structures in autoradiograms of brain sections. These results show that quantitative autoradiography can be used to characterize the local metabolism of antiviral drugs by infected cells in vivo. They also suggest that the selective uptake of drugs that exploit viral thymidine kinase for their antiviral effect can, by appropriate labeling, be used in conjunction with clinical neuroimaging techniques to define infected regions of human brain, thereby providing a new approach to the diagnosis of herpes encephalitis in man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saito, Y -- Price, R W -- Rottenberg, D A -- Fox, J J -- Su, T L -- Watanabe, K A -- Philips, F S -- New York, N.Y. -- Science. 1982 Sep 17;217(4565):1151-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112121" 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〉

    Publication Date: 1982-04-02
    Description: Autoradiography demonstrated prominent retrograde labeling of olivocerebellar climbing fiber neurons after injection of tritiated D-aspartate into the rat cerebellar cortex or deep nuclei. Mossy fiber systems originating in the brainstem and spinal cord remained unlabeled. Potassium ion-induced depolarization of cerebellar slices resulted in calcium ion-dependent release of endogenous L-aspartate, L-glutamate, gamma-aminobutyric acid, and glycine. A 26 percent decrease in aspartate release was observed after 3-acetylpyridine-induced destruction of the inferior olive, supporting the hypothesis that aspartate is a neurotransmitter in climbing fibers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wiklund, L -- Toggenburger, G -- Cuenod, M -- New York, N.Y. -- Science. 1982 Apr 2;216(4541):78-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6121375" target="_blank"〉PubMed〈/a〉

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〉

    Description: Transfer RNA's are probably very strongly selected for translational efficiency. In this article, the argument is presented that the coding performance of the triplet anticodon is enhanced by selection of a matching anticodon loop and stem sequence. the anticodon plus these nearby sequence features (the extended anticodon) therefore contains more coding information than the anticodon alone and can perform more efficiently and accurately at the ribosome. This idea successfully accounts for the relative efficiencies of many transfer RNA's.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yarus, M -- New York, N.Y. -- Science. 1982 Nov 12;218(4573):646-52.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6753149" target="_blank"〉PubMed〈/a〉

    Description: The gamma-aminobutyric acid (GABA)-benzodiazepine receptor complex, which is composed of distinct proteins embedded in the neuronal plasma membrane, is important for several effects of benzodiazepines, including protection afforded against convulsions. During structural modification of ethyl beta-carboline-3-carboxylate an agent was discovered which has high affinity for brain benzodiazepine receptors but which is a potent convulsant. Also in contrast to benzodiazepines, this type of benzodiazepine receptor ligand favors benzodiazepine receptors in the non-GABA-stimulated conformation, which may explain the convulsive properties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Braestrup, C -- Schmiechen, R -- Neef, G -- Nielsen, M -- Petersen, E N -- New York, N.Y. -- Science. 1982 Jun 11;216(4551):1241-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6281892" target="_blank"〉PubMed〈/a〉

    Focal cortical seizures cause distant thalamic lesions (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-08
    Description: Topical application of convulsants to the rat sensorimotor cortex in concentrations sufficient to cause repetitive focal motor seizures resulted in acute neuropathology (dark cell neuronal degeneration and spongiform neurophil changes) involving both the cortical seizure focus and certain thalamic nuclei within seizure pathways. Changes in the cortex were localized primarily in layer IV and those in the thalamus in nuclei having reciprocal connections with the cortical focus. The spongiform neuropil changes consisted of massively dilated presynaptic axon terminals in the cortex and postsynaptic dendrites in the thalamus. The dendritic and dark cell changes resemble the excitotoxic damage caused by glutamate and aspartate. Since these putative transmitters may be released locally from recurrent collaterals and remotely from corticothalamic axons, excessive release of glutamate or aspartate may account for the changes in both sites. The abnormal axons in sensory cortex appear to be terminals of thalamocortical neurons. Swelling of these axons may be caused by excessive anti- and orthodromic firing in the course of focal motor seizures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Collins, R C -- Olney, J W -- MH-38894/MH/NIMH NIH HHS/ -- NS-09156/NS/NINDS NIH HHS/ -- NS-14834/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):177-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123229" target="_blank"〉PubMed〈/a〉

    Fragment spanning the SV40 replication origin is the only DNA sequence required in cis for viral excision (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-17
    Description: A 311-base pair fragment containing the SV40 origin of replication was linked to the chicken thymidine kinase gene on a recombinant plasmid. This molecule was transfected into human 143 thymidine kinase-deficient (TK-) cells, and colonies positive for thymidine kinase were selected. When cell lines derived from these colonies were fused to permissive simian cells that produce SV40 T antigen, the recombinant plasmid excised itself from the human cellular genome and replicated with a high copy number per cell. These results show that this segment of the viral genome is the only sequence required in cis to mediate SV40 excision and replication upon fusion to permissive cells. In addition, we have shown that excised plasmids apparently identical to the input DNA can be efficiently rescued in Escherichia coli. SV40 excision and replication may therefore be useful for the recovery of cloned genes from eukaryotic cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conrad, S E -- Liu, C P -- Botchan, M R -- CA 30490/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 17;218(4578):1223-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6293055" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-08-27
    Description: Cellular genes potentially capable of inducing oncogenic transformation have been identified by homology to the transforming genes of retroviruses and by the biological activity of cellular DNA's in transfection assays. DNA's of various tumors induce transformation with high efficiencies, indicating that oncogenesis can involve dominant genetic alterations resulting in activation of cellular transforming genes. The identification and characterization of cellular transforming genes and their possible involvement in naturally occurring cancers, is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cooper, G M -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):801-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6285471" target="_blank"〉PubMed〈/a〉

    Molecular biology of the sea urchin embryo (1982)

    Details
    Publication Date: 1982-07-02
    Description: Research on the early development of the sea urchin offers new insights into the process of embryogenesis. Maternal messenger RNA stored in the unfertilized egg supports most of the protein synthesis in the early embryo, but the structure of maternal transcripts suggests that additional functions are also possible. The overall developmental patterns of transcription and protein synthesis are known, and current measurements describe the expression of specific genes, including the histone genes, the ribosomal genes, and the actin genes. Possible mechanisms of developmental commitment are explored for regions of the early embryo that give rise to specified cell lineages, such as the micromere-mesenchyme cell lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davidson, E H -- Hough-Evans, B R -- Britten, R J -- GM20927/GM/NIGMS NIH HHS/ -- HD05753/HD/NICHD NIH HHS/ -- RR00986/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Jul 2;217(4554):17-26.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178156" target="_blank"〉PubMed〈/a〉

    Habituation and sensitization of startle reflexes elicited electrically from the brainstem (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-12
    Description: Repetitive elicitation of startle-like responses by electrical stimulation of the cochlear nucleus led to sensitization followed by habituation. 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〉

    Events in the evolution of pre-proinsulin (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-20
    Description: An extensive computer-assisted analysis of known pre-proinsulin coding sequences has shown correlations that can be interpreted as evidence for an intron-mediated juxtaposition of exons in the evolution of these genes. The evidence includes the discovery that the regions of the pre-proinsulin genes that code for the signal peptide consist of nearly tandem repeating units of nine base pairs. This pattern reappears in the C region of the genes after a large intron that occurs in three of the four genes analyzed. A model is proposed in which primordial insulin was coded for by two separate minigenes arising from a gene duplication, each with identical or nearly identical signal peptide coding regions. The minigenes fused into one transcriptional unit mediated by the large intron, and the signal peptide coding region of one of the putative minigenes evolved into the latter portion of the C peptide coding region.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Douthart, R J -- Norris, F H -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):729-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100918" target="_blank"〉PubMed〈/a〉

    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〉

    Chemoprevention of neonatal jaundice: potency of tin-protoporphyrin in an animal model (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-09-24
    Description: The substantial increases of hepatic, splenic, and renal heme oxygenase levels that occur shortly after birth in neonatal rats were prevented by a single administration of tin-protoporphyrin (10 micromoles per kilogram of body weight). With this treatment serum bilirubin levels declined within 24 hours to near-normal adult levels and remained low throughout the postnatal period. Zinc-protoporphyrin at doses up to 50-fold greater than the effective dose of tin-protoporphyrin did not prevent the immediate increases in tissue heme oxygenase activities and in serum bilirubin levels that occur postnatally. Studies in vitro with microsomal heme oxygenase in human spleen indicate that tin-protoporphyrin is a potent competitive inhibitor of the oxidation of heme to bile pigment in this tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drummond, G S -- Kappas, A -- ES-01055/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 24;217(4566):1250-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6896768" 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: A protein macromolecule in the cytosol of the unicellular eukaryotic yeast Saccharomyces cerevisiae selectively binds the vertebrate estrogen hormone 17 beta-estradiol with high affinity. Lipid extracts of the yeast cells or the conditioned growth medium yield a substance that can bind competitively to the tritiated estradiol-binding sites in the yeast and to mammalian estrogen receptors. These findings suggest that the binding protein may be a primitive hormone receptor and that the lipid-extractable substance represents the endogenous ligand.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feldman, D -- Do, Y -- Burshell, A -- Stathis, P -- Loose, D S -- GM28825/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 15;218(4569):297-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6289434" target="_blank"〉PubMed〈/a〉

    Description: A new process has been developed which is called "Boradeption" to signify boronic acid--dependent phase transfer of water-insoluble agents. Highly fluorescent boronic acid dervatives, FluoroBoras, are solubilized with a physiologically compatible carrier buffer containing a receptor group for boronate adduct formation. The system can be used to stain living cells. In another variation of the Boradeption concept, an insoluble reporter molecule containing a boronate receptor is solubilized with a carrier buffer containing a boronic acid functional group. The boronate-receptor complexes, which are in dynamic equilibrium, can be designed as vital stains and reagents for a variety of biological and medical applications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallop, P M -- Paz, M A -- Henson, E -- AG-00376-07/AG/NIA NIH HHS/ -- HL-20764-04A1/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 9;217(4555):166-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178158" target="_blank"〉PubMed〈/a〉

However, when these two derivatives were administered systemically, their anti-inflammatory activities were weaker than those of the parent compound. Furthermore, unlike the parent compound, these new anti-inflammatory steroids did not suppress pituitary-adrenal function or cause liver glycogen depletion in rats.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, H J -- Soliman, M R -- AM 21627/AM/NIADDK NIH HHS/ -- RR 08111/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):989-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6296999" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-06-18
    Description: Nuclear magnetic resonance imaging was used to determine quantitatively the water distribution of saline-filled and normal rat lungs in both isolated lung and in situ preparations. Regional lung edema was easily detected. Studies of an isolated lung fragment indicate an accuracy of better than 1 percent and images of H2O/D2O phantoms indicate an average error of 2.7 percent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hayes, C E -- Case, T A -- Ailion, D C -- Morris, A H -- Cutillo, A -- Blackburn, C W -- Durney, C H -- Johnson, S A -- 2 R01 HL 23746-03/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Jun 18;216(4552):1313-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079763" 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〉

    Homologous regulation of gonadotropin-releasing hormone receptors in cultured pituitary cells (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-19
    Description: Specific receptors for gonadotropin-releasing hormone (GnRH) in cultured rat pituitary cells were increased by subnanomolar concentrations of GnRH agonists and decreased by high concentrations of these peptides. The antagonist [D-Phe2, Pro3, D-Phe6]GnRH did not alter GnRH binding capacity and blocked the increase in sites induced by GnRH. These findings provide direct evidence for the homologous regulation of GnRH receptors by physiological concentrations of the hypothalamic peptide, an action that could mediate the cyclical and postcastration increases in GnRH receptors and responsiveness of the pituitary gonadotrophs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loumaye, E -- Catt, K J -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):983-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6296998" target="_blank"〉PubMed〈/a〉

    Intracellular oxidation-reduction state measured in situ by a multichannel fiber-optic surface fluorometer (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    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〉

This method allows small clusters of nucleotide residues to be substituted in a site-directed manner without causing the addition or deletion of other sequences.

    Description: A 3.4-kilobase DNA fragment containing the gene coding for the E alpha chain of an Ia (I region-associated) antigen from the BALB/c mouse has been sequenced. It contains at least three exons, which correlate with the major structural domains of the E alpha chain-the two external domains alpha 1 and alpha 2, and the transmembrane-cytoplasmic domain. The coding sequence of the mouse E alpha gene shows striking homology to its counterpart at the DNA and protein levels. The translated alpha 2 exon demonstrates significant similarity to beta 2-microglobulin, to immunoglobulin constant region domains, and to certain domains of transplantation antigens. These observations and those of others suggest that the Ia antigen, transplantation antigen, and immunoglobulin gene families share a common ancestor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McNicholas, J -- Steinmetz, M -- Hunkapiller, T -- Jones, P -- Hood, L -- New York, N.Y. -- Science. 1982 Dec 17;218(4578):1229-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6815800" target="_blank"〉PubMed〈/a〉

    Synaptic cleft glycoproteins contain homologous amino acid sequences (1982)
    American Association for the Advancement of Science (AAAS)

    Description: The concanavalin A--binding glycoproteins of the rat synaptic junction were isolated by affinity chromatography. These glycoproteins had molecular weights of 160,000, 123,000, 110,000, and 95,000. The tryptic peptide maps of these glycoproteins showed that the three largest glycoproteins contained a high percentage of identical peptides. This indicates that the amino acid sequences of these glycoproteins have a high degree of homology. The 95,000-dalton glycoprotein was unrelated to the other three. These findings suggest that homologous glycoproteins may participate in synapse formation or maintenance, or both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mena, E E -- Cotman, C W -- New York, N.Y. -- Science. 1982 Apr 23;216(4544):422-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7071591" target="_blank"〉PubMed〈/a〉

    Origin of the cholecystokinin-containing fibers in the rat caudatoputamen (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-08
    Description: Large Amounts of cholecystokinin-octapeptide (CCK) are present in the rat caudatoputamen. The peptide occurs in axons and nerve endings but not in perikarya. The origin of CCK in the caudatoputamen was investigated with the use of immunocytochemistry and a radioimmunoassay specific for CCK. Although a small amount of CCK (approximately 30 percent) originates in the amygdaloid complex, the bulk of the peptide (approximately 70 percent) occurs in processes of neurons located ventral to the caudatoputamen, that is, the claustrum or the piriform cortex. The claustrum and piriform cortex receive inputs from various cortical areas and the olfactory system, respectively, and may process information and relay it to the caudatoputamen. Thus CCK may by the transmitter in the final common pathway linking various cortical areas and the olfactory system to the caudatoputamen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, D K -- Beinfeld, M C -- Oertel, W H -- Brownstein, M J -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):187-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053570" target="_blank"〉PubMed〈/a〉

    Description: Cysteamine rapidly reduces the concentration of prolactin in pituitary tissue in vivo and in vitro. The effect is dose-dependent, reversible, and cannot be accounted for by prolactin release. Cysteamine does not appear to exert its effect through dopamine receptors and does not alter lactotrope morphology, as determined by electron microscopy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Millard, W J -- Sagar, S M -- Landis, D M -- Martin, J B -- AM 26252/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):452-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089575" target="_blank"〉PubMed〈/a〉

    Neonatal treatment with antiserum to prolactin lowers blood pressure in rats (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    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〉

    Description: The sequence of a gene, denoted 27.5, encoding a transplantation antigen for the BALB/c mouse has been determined. Gene transfer studies and comparison of the translated sequence with the partial amino acid sequence of the Ld transplantation antigen establish that gene 27.5 encodes an Ld polypeptide. A comparison of the gene 27.5 sequence with several complementary DNA sequences suggests that the BALB/c mouse may contain a number of closely related L-like genes. Gene 27.5 has eight exons that correlate with the structural domains of the transplantation antigen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, K W -- Sher, B T -- Sun, Y H -- Eakle, K A -- Hood, L -- 1 T32 GM07616/GM/NIGMS NIH HHS/ -- GM 06965/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 5;215(4533):679-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058332" target="_blank"〉PubMed〈/a〉

    Description: A method combining steroid autoradiography and fluorescent dye retrograde neuroanatomical tracing has been devised. This method makes it possible to demonstrate that some estrogen-concentrating cells in the ventrolateral subdivision of the ventromedial nucleus of the rat hypothalamus are neurons that send axons to the dorsal midbrain. Other cells only concentrate estrogen or only project to the midbrain. Estrogen-concentrating neurons in the ventromedial hypothalamus that project to the dorsal midbrain are likely to transmit hormone-influenced signals that regulate circuits for reproductive or other behaviors or autonomic functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrell, J I -- Pfaff, D W -- New York, N.Y. -- Science. 1982 Sep 24;217(4566):1273-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112131" target="_blank"〉PubMed〈/a〉

    Description: The conformation and dynamics of the d(CGCGAATTCGCG) duplex, its analogs containing mismatched base pairs and helix interruptions, and its complexes with actinomycin and Netropsin, bound separately and simultaneously, have been investigated by nuclear magnetic resonance spectroscopy in aqueous solution. Structural information has been deduced from chemical shift and nuclear Overhauser effect parameters, while the kinetics have been probed from line width and saturation recovery experiments on proton and phosphorus markers at the individual base pair level. These studies lead to an improved understanding of the role of nucleic acid sequence on the structure, flexibility, and conformational interconversions in the duplex state. The nuclear magnetic resonance measurements readily identify helix modification and antibiotic binding sites on the nucleic acid and estimate the extent to which the observed conformational and dynamic perturbations are transmitted to adjacent base pair regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Patel, D J -- Pardi, A -- Itakura, K -- New York, N.Y. -- Science. 1982 May 7;216(4546):581-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6280281" 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〉

    Nonopiate effects of dynorphin and des-Tyr-dynorphin (1982)

    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〉

    Description: An experiment with rats has demonstrated that Pavlovian conditioning factors determine the occurrence of tolerance to haloperidol catalepsy. Rats exhibited tolerance only in the environment previously associated with the drug. Previous research involving receptor binding techniques implicated an increase in the number of brain dopamine receptors as the mediator of neuroleptic tolerance. The present findings demonstrate that this change, by itself, cannot account for the conditional occurrence of such tolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poulos, C X -- Hinson, R -- New York, N.Y. -- Science. 1982 Oct 29;218(4571):491-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6889765" target="_blank"〉PubMed〈/a〉

    Description: The activity of nucleoside triphosphatase, an enzyme that regulates nuclear messenger RNA transport, was measured in highly purified nuclear envelopes isolated from rat liver. Addition of picomolar concentrations of insulin to freshly prepared nuclear envelopes directly increased the enzyme activity. The major effect of insulin on this enzyme was to increase the maximum velocity of its activity; no significant effects were seen on the affinity constant. These studies raise the possibility, therefore, that the nuclear envelope is a site where insulin regulates nuclear functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Purrello, F -- Vigneri, R -- Clawson, G A -- Goldfine, I D -- AM 26667/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 May 28;216(4549):1005-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6281885" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)

    Publication Date: 1982-07-02
    Description: Administration of synthetic ovine corticotropin-releasing factor led to rapid, parallel increases in adrenocorticotropin and alpha-melanocyte-stimulating hormone concentrations in rat plasma. Prior treatment with dexamethasone almost completely blocked the adrenocorticotropin response but not the increase in melanocyte-stimulating hormone. These data demonstrate that corticotropin-releasing factor is a potent stimulator not only of adrenocorticotropin secretion from the corticotrophs of the anterior pituitary gland but also of peptide secretion from the intermediate lobe. Such data suggest that melanocyte-stimulating hormone and beta-endorphin play a role in the physiological response to stress.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Proulx-Ferland, L -- Labrie, F -- Dumont, D -- Cote, J -- Coy, D H -- Sveiraf, J -- New York, N.Y. -- Science. 1982 Jul 2;217(4554):62-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6283632" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-12-10
    Description: A study of the anatomical distribution of the endogenous opioid dynorphin in rat brain showed that the peptide is localized in a widespread system with multiple cell groups and projections. This network is revealed by the use of multiple antiserums against dynorphin and can be distinguished from the system containing methionine-enkephalin and leucine-enkephalin, which is mapped by the use of antiserums against the enkephalins and biosynthetically related peptides in the adrenal. It thus appears that the brain contains at least three separate opioid neuronal networks: an enkephalin family with components similar to those found in the adrenal, a beta-endorphin family, and a dynorphin family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, S J -- Khachaturian, H -- Akil, H -- Coy, D H -- Goldstein, A -- DA00154/DA/NIDA NIH HHS/ -- DA02265/DA/NIDA NIH HHS/ -- MH15794/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1134-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6128790" target="_blank"〉PubMed〈/a〉

    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〉

    Diverse mechanisms in the generation of human beta-tubulin pseudogenes (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-06
    Description: The sequence of two human beta-tubulin pseudogenes is described. One contains an intervening sequence but lacks sequences encoding the 55 N-terminal amino acids of the polypeptide chain. A second has no introns but has a polyadenylate signal and an oligoadenylate tract at its 3' end, and it is flanked by a short direct repeat. These sequences have arisen by different mechanisms, including one that probably involves reverse transcription of a processed messenger RNA and reintegration of the complementary DNA copy into the genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilde, C D -- Crowther, C E -- Cowan, N J -- GM26456/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 6;217(4559):549.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178164" target="_blank"〉PubMed〈/a〉

    Different synaptic location of mianserin and imipramine binding sites (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-26
    Description: The high-affinity binding sites for mianserin and imipramine appear to be locate in different neurons of rat brain. Studies in which lesions were produced with 5,7-dihydroxytryptamine and other studies in which the 5-hydroxytryptamine content was decreased with p-chlorophenylalanine indicate that some of the imipramine binding sites are on serotonin axon terminals and others are on nonserotonergic synapses. The sites that bind mianserin are on postsynaptic serotonin sites as well as on synapses of other neuronal systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brunello, N -- Chuang, D M -- Costa, E -- New York, N.Y. -- Science. 1982 Feb 26;215(4536):1112-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6278586" target="_blank"〉PubMed〈/a〉

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

    Postural asymmetry and movement disorder after unilateral microinjection of adrenocorticotropin 1-24 in rat brainstem (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-10-08
    Description: A unilateral microinjection of adrenocorticotropin 1-24 in the rat brainstem in the region of the locus ceruleus resulted in postural asymmetry and movement disorder that resembled human dystonia, the severity and duration (2 to 3 days) being dose-dependent. 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〉

    Hyperglycemia of diabetic rats decreased by a glucagon receptor antagonist (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    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〉

    Role of serotonergic input in the regulation of the beta-adrenergic receptor-coupled adenylate cyclase system (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-26
    Description: The action of desipramine on the norepinephrine-sensitive adenylate cyclase system and the density of beta-adrenergic receptors in rat cortex was studied after selective lesioning of serotonergic neurons with 5,7-dihydroxytryptamine. 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〉
