    Cholinergic vesicles: ability to empty and refill independently of cytoplasmic acetylcholine (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-01-06
    Beschreibung: Incubation of minced mouse-forebrain tissues in lithium Krebs solution reduces the acetylcholine content of the vesicular fraction 70 percent without altering that of the cytoplasmic fraction. Depleted vesicular-bound acetylcholine can be restored with newly synthesized acetylcholine (formed from extracellular choline) independently of the cytoplasmic pool. Depletion of vesicular-bound acetylcholine does not facilitate the movement of preformed extracellular acetylcholine into vesicles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carrol, P T -- Nelson, S H -- New York, N.Y. -- Science. 1978 Jan 6;199(4324):85-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Toxicology, University of Rhode Island, Kingston, RI 02881, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17569492" target="_blank"〉PubMed〈/a〉

    Sulfhydryl groups and the monodeiodination of thyroxine to triiodothyronine (1978)

    Beschreibung: Sulfhydryl reagents exert a profound influence on the monodeiodination of thyroxine to triiodothyronine by rat and sheep tissues in vitro. A marked dithiothreitol-induced increase in the monodeiodination by fetal sheep liver homogenates suggests that the characteristically low conversion in fetal tissues is related more to the status of sulfhydryl groups than to a deficiency of the monodeiodinating enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chopra, I J -- New York, N.Y. -- Science. 1978 Feb 24;199(4331):904-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622575" target="_blank"〉PubMed〈/a〉

    Tricyclic antidepressants: long-term treatment increases responsivity of rat forebrain neurons to serotonin (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-12-22
    Beschreibung: Long-term treatment of rats with clinically effective tricyclic antidepressant drugs induced a selective increase in the inhibitory response of forebrain neurons to serotonin applied by microiontophoresis. Long-term administration of some related drugs which lack antidepressant efficacy failed to induce such a change. The enhanced response to serotonin induced by the clinically active tricyclic drugs took 1 to 2 weeks to develop, a time course which correlates with the delayed onset of therapeutic effects in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Montigny, C -- Aghajanian, G K -- New York, N.Y. -- Science. 1978 Dec 22;202(4374):1303-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/725608" target="_blank"〉PubMed〈/a〉

    The stomach signals satiety (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-07-14
    Beschreibung: Inflatable pyloric cuffs and stomach tubes were implanted in rats. With the cuff inflated and a valve to limit intragastric pressure to that accompanying normal satiety, they drank only as much when they had been deprived of food for 12 hours as without inflation of the cuff. However, they overdrank with the cuff inflated when they had been water deprived for 12 hours. When 10 ml of milk was withdrawn from the stomach with the cuff inflated, compensatory drinking occurred. Further, compensatory drinking also occurred when milk escaped from the stomach into the duodenum. Satiety signals thus arise from the stomach.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deutsch, J A -- Young, W G -- Kalogeris, T J -- New York, N.Y. -- Science. 1978 Jul 14;201(4351):165-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663647" target="_blank"〉PubMed〈/a〉

    Nucleosome arcs and helices (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-10-20
    Beschreibung: Crystals and other regular arrangements of nucleosome cores have been obtained and analyzed in the electron microscope. Two types of regular structures have been studied in detail, the nucleosome arcs and cylinders. The latter are composed of concentric cylindrical layers of intertwined right-handed helices of nucleosome cores. These studies lead to the following conclusions and concepts. The overall structure of the nucleosome core is a short, wedge-shaped cylinder measuring about 110 by 110 by 60 angstroms. Nucleosome cores interact primarily between top and bottom planes. Nucleosome cores exhibit large conformational variability. A pivot allowing two degrees of rotational freedom is postulated in the region of the 70th base pair to account for this property of the nucleosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dubochet, J -- Noll, M -- New York, N.Y. -- Science. 1978 Oct 20;202(4365):280-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/694532" target="_blank"〉PubMed〈/a〉

    Dual actions of substance P on nociception: possible role of endogenous opioids (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-03-24
    Beschreibung: Substance P produces analgesia when administered to mice in very small doses by the intraventricular route (1.25 to 5 nanograms per mouse). The analgesic effect can be blocked by naloxone. At higher doses (greater than 50 nanograms per mouse), this activity is lost. At these higher doses, however, substance P produced hyperalgesia when combined with naloxone and analgesia when combined with baclofen [beta-(4-chlorophenyl)-gamma-aminobutyric acid]. Substance P may have dual actions in brain, releasing endorphins at very low doses and directly exciting neuronal activity in nociceptive pathways at higher doses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frederickson, R C -- Burgis, V -- Harrell, C E -- Edwards, J D -- New York, N.Y. -- Science. 1978 Mar 24;199(4335):1359-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/204012" target="_blank"〉PubMed〈/a〉

    beta-Adrenergic receptors in aged rat brain: reduced number and capacity of pineal gland to develop supersensitivity (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-07-07
    Beschreibung: The density but not the affinity of beta-adrenergic receptors declined significantly with age in rat pineal gland, corpus striatum, and cerebellum, as determined by the binding of tritiated dihydroalprenolol. Exposing rats to light for 12 hours increased the binding of this radioligand in 3-month-old but not in 24-month-old rats. The reduced responsiveness to catecholamines seen in aging may be due to a decrease in the number of beta-adrenergic receptors which, in turn, may be caused by an impaired capacity of receptors in aged animals to adapt to changes in adrenergic neuronal input.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greenberg, L H -- Weiss, B -- New York, N.Y. -- Science. 1978 Jul 7;201(4350):61-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/208145" target="_blank"〉PubMed〈/a〉

    Subsynaptic plate perforations: changes with age and experience in the rat (1978)

    Details
    Publikationsdatum: 1978-12-08
    Beschreibung: The relative frequency of appearance of discontinuities in the postsynaptic thickening, or perforations in the subsynaptic plate, increased with age and experience. Rats reared from weaning in complex or social environments had a significantly higher proportion of occipital cortical synapses with perforations than did rats reared in isolation. In addition, the relative frequency of these perforations more than tripled between 10 and 60 days of age. Shifts in the frequency of perforations can occur independently of changes in the size of synpases. This result suggests a new potential mechanism of synaptic plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greenough, W T -- West, R W -- DeVoogd, T J -- New York, N.Y. -- Science. 1978 Dec 8;202(4372):1096-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/715459" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1978-07-28
    Beschreibung: Rat pups that are separated early from their mothers, at postnatal day 15, become hypothermic when subjected to physical restraint on postnatal day 30. Restraint of separated pups also elicits an unusually high incidence of gastric erosions, as well as insomnia and an increase in quiet wakefulness. If hypothermia during restraint is prevented, neither the erosions nor the behavioral responses occur. Rat pups separated at the customary age (postnatal day 22) do not become hypothermic during restraint, and the restraint of such pups is not associated with either gastric erosion or insomnia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ackerman, S H -- Hofer, M A -- Weiner, H -- New York, N.Y. -- Science. 1978 Jul 28;201(4353):373-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/566471" target="_blank"〉PubMed〈/a〉

    Chronically decerebrate rats demonstrate satiation but not bait shyness (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-07-21
    Beschreibung: Taste substances applied to the oral cavity result in either ingestion or rejection, each with a characteristic muscular response pattern. These responses are the same in decerebrate and intact rats; the caudal brainstem appears to be the neural substrate of ingestion and rejection responses. The experiment determined whether decerebrates can alter these discriminative responses as a function of food deprivation or toxicosis. Food-deprived decerebrate rats, like intact ones, ingested a taste substance they had rejected when sated. However, these same decerebrates, in contrast to controls, neither rejected nor decreased ingestive reactions to a novel taste after that taste had been repeatedly paired with lithium chloride-induced illness. Although the forebrain may be important for integrating ingestion, some aspects of this control seem to be represented in caudal brain areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grill, H J -- Norgren, R -- New York, N.Y. -- Science. 1978 Jul 21;201(4352):267-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663655" target="_blank"〉PubMed〈/a〉

    Beschreibung: Microinjections of the excitatory neurotoxin kainic acid into the lateral hypothalamus of rats produced a period aphagia and adipsia. Kainate-treated rats displayed transient motor effects during the first hours after the injection but did not show the persisting sensory-motor and arousal disturbances typically observed in animals with electrolytic lesions in this part of the hypothalamus. Histological examination revealed a significant reduction in the number of nerve cell bodies in the lateral hypothalamus. Silver-stained material indicated no evidence of damage to fiber systems passing through the affected region. Assays of dopamine in hypothalamus, striatum, and telencephalon did not indicate significant differences between experimental and control animals. These results are in agreement with recent reports of the anatomical and biochemical effects of intracerebral kainic acid injections and suggest that the observed effect on feeding behavior is related to the destruction of neurons in the lateral hypothalamus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grossman, S P -- Dacey, D -- Halaris, A E -- Collier, T -- Routtenberg, A -- New York, N.Y. -- Science. 1978 Nov 3;202(4367):537-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/705344" target="_blank"〉PubMed〈/a〉

    Phagocytosis of light- and dark-adapted rod outer segments by cultured pigment epithelium (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-11-03
    Beschreibung: Pigment epithelial cells in culture retain their ability to phagocytize rod outer segments. These cells phagocytize rod outer segments isolated from light-adapted rats, or from dark-adapted rats killed after the time at which the lights would normally be turned on. However, they phagocytize for fewer rod outer segments prepared in the dark from the retinas of rats killed before the onset of the normal light cycle. Phagocytosis of dark rod outer segments is variable, but that of light outer segments is reproducible. It is postulated that the effect of light is to synchronize the chemical events that occur at the surface of the rods to prepare them for phagocytosis. These processes also occur in the dark, but more slowly and irregularly than in the light.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, M O -- New York, N.Y. -- Science. 1978 Nov 3;202(4367):526-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/568310" target="_blank"〉PubMed〈/a〉

    Stimulation of dopamine synthesis in caudate nucleus by intrastriatal enkephalins and antagonism by naloxone (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-05-05
    Beschreibung: The intraventricular injection of methionine-enkephalin (50 to 100 micrograms) or [d-Ala2]-methionine-enkephalinamide (1.5 to 12 micrograms), a synthetic enkephalin analog resistant to enzyme degradation, caused a marked dose-dependent increase in dihydroxyphenylacetic acid and homovanillic acid concentrations in the rat striatum. The [d-Ala2] analog increased the accumulation of dopa in the striatum after aromatic amino acid decarboxylase inhibition, indicating that it increased dopamine synthesis. At the highest doses used both enkephalins failed to modify brain serotonin metabolism. The monolateral microinjection of the [d-Ala2]] analog (3 to 6 micrograms) into the caudate nucleus increased the concentration of dihydroxyphenylacetic acid in the injected side, whereas bilateral injection increased the concentration of this compound in both caudate nuclei and caused catalepsy. The stimulant effect of the [d-Ala2] analog on dopamine synthesis in the striatum persisted after destruction of striatal postsynaptic dopamine receptors with kainic acid. The biochemical and behavioral effects of enkephalins were prevented by naloxone, a specific narcotic antagonist. The results indicate that enkephalins stimulate dopamine synthesis by an action on opioid receptors localized on dopaminergic nerve terminals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biggio, G -- Casu, M -- Corda, M G -- Di Bello, C -- Gessa, G L -- New York, N.Y. -- Science. 1978 May 5;200(4341):552-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/205949" target="_blank"〉PubMed〈/a〉

    Blood-brain neutral amino acid transport activity is increased after portacaval anastomosis (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-06-23
    Beschreibung: In rats after portacaval anastomosis (an animal model of chronic liver disease), transport of tryptophan and other members of the large neutral amino acid group from blood to brain was markedly enhanced. Increased transport activity was apparently restricted to the neutral amino acid transport system, since brain uptake of glucose, inulin, and tyramine was unaffected while blood-brain arginine transport was significantly reduced. These results strikingly confirm the hypothesis that carrier-mediated blood-brain transport is the limiting factor determining the availability of the neutral amino acids to the brain. The encephalopathy associated with cirrhosis may be the result of abnormal neurotransmitter metabolism and neurotransmission secondary to increased neutral amino acid transport activity and an increased brain content of members of the neutral amino acid group.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉James, J H -- Escourrou, J -- Fischer, J E -- New York, N.Y. -- Science. 1978 Jun 23;200(4348):1395-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663619" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1978-03-03
    Beschreibung: Human circulating monocytes in tissue culture are capable of resorbing devitalized adult and fetal bone. An important component of this process is the adhesion of the cells to the mineralized substrate and the localized removal of matrix from beneath the attached cells. The process appears to involve both release of lysosomal enzymes onto the substrate and intracellular accumulation (transport) of resorbed matrix.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kahn, A J -- Stewart, C C -- Teitelbaum, S L -- New York, N.Y. -- Science. 1978 Mar 3;199(4332):988-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622581" target="_blank"〉PubMed〈/a〉

    Modification of attention in honey bees (1978)

    Publikationsdatum: 1978-09-29
    Beschreibung: Honey bees were trained in two consecutive two-dimensional (color-position) problems with one dimension (color or position) relevant and the other irrelevant in each problem. As in analogous experiments on dimensional transfer in rats and monkeys, performance in the second problem was more accurate when the relevant and irrelevant dimensions were the same as in the first problem than when they were interchanged. The results of further experiments suggest that the transfer is mediated by different modes of responding that develop in color and position problems rather than by some special process of dimensional selection, such as has been assumed to operate in vertebrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klosterhalfen, S -- Fischer, W -- Bitterman, M E -- New York, N.Y. -- Science. 1978 Sep 29;201(4362):1241-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/694513" target="_blank"〉PubMed〈/a〉

    Increased resistance to Staphylococcus aureus infection and enhancement in serum lysozyme activity by glucan (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-03-24
    Beschreibung: Glucan is a potent reticuloendothelial stimulant whose immunobiological activity is mediated, in part, by an increase in the number and function of macrophages. In studying the role of glucan as a mediator of antibacterial activity, we attempted to ascertain the ability of glucan to modify the mortality of mice with experimentally induced Gram-positive bacteremia, and to enhance antibacterial defenses in rats as denoted by serum lysozyme and phagocytic activity. After intravenous administration of glucan, serum lysozyme concentrations were increased approximately sevenfold over control concentrations. The increase in serum lysozyme appeared to parallel the glucan-induced increase in phagocytosis and induced hyperplasia of macrophages. Prior treatment of mice with glucan significantly enhanced their survival when they were challenged systemically with Staphylococcus aureus. These studies indicate that glucan confers an enhanced state of host defense against bacterial infections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kokoshis, P L -- Williams, D L -- Cook, J A -- Di Luzio, N R -- New York, N.Y. -- Science. 1978 Mar 24;199(4335):1340-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/628841" target="_blank"〉PubMed〈/a〉

    Pineal serotonin N-acetyltransferase activity: abrupt decrease in adenosine 3',5'-monophosphate may be signal for "turnoff" (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-01-20
    Beschreibung: Dispersed pinealocytes have been used to study the role of adenosine 3',5'-monophosphate (cyclic AMP) in the "turnoff" of N-acetyltransferace activity. Activity was first stimulated 100-fold by treating cells with 1-norepinephrine. 1-Propranolol acted stereospecifically to rapidly reverse this, resulting in a 70 percent loss of enzyme activity within 15 minutes. An even more rapid 1-propranolol-induced decreased in cyclic AMP also occurred. This together with the observation that the inhibitory effect of 1-propranolol on N-acetyltransferase was blocked by dibutyryl cyclic AMP and phosphodiesterase inhibitors indicate that an abrupt decrease in cyclic AMP may be the signal for the rapid decrease in pineal N-acetyltransferase activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klein, D C -- Buda, M J -- Kapoor, C L -- Krishna, G -- New York, N.Y. -- Science. 1978 Jan 20;199(4326):309-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/202027" target="_blank"〉PubMed〈/a〉

The most striking effects were on bone formation. During flight, rats formed significantly less periosteal bone than did control rats on the ground. An arrest line at both the periosteum and the endosteum of flight animals suggest that a complete cessation of bone growth occurred. During a 26-day postflight period, the defect in bone formation was corrected.

However, after treatment of the cells with a nontransforming initiating dose (0.1 microgram per milliliter) of 3-methylcholanthrene, continuous treatment with either sample of saccharin (100 micrograms per milliliter) led to significant transformation.

    Beschreibung: Animals receiving low-intensity electrical stimulation of the basolateral nucleus of the amygdala while drinking plain tap water were injected with toxic doses of lithium chloride to examine whether brain stimulation can serve as a conditioned stimulus in a bait-shyness paradigm. Subjects receiving this pairing greatly reduced their water intake in a retention test, in a similar manner to a group in which saccharin was paired with poisoning. Pairing lithium chloride with stimulation of the amygdala had no effect on subsequent water intake in the absence of brain stimulation. This effect appears to be locus specific, as caudate stimulation could not serve as a conditioned stimulus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phillips, A G -- LePiane, F G -- New York, N.Y. -- Science. 1978 Aug 11;201(4355):536-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663673" target="_blank"〉PubMed〈/a〉

    Beschreibung: The inability of nursing pups to survive on milk of mice homozygous for the recessive mutation, lethal milk (lm), is correlated with a reduction in zinc levels of both milk and pup carcass. Administration of zinc to pups nursing on lmlm dams reduces the observed mortality and morbidity. It is suggested that lm alters zinc transport from maternal blood to milk and that its study may provide useful information for understanding the rare human disease, acrodermatitis enteropathica.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Piletz, J E -- Ganschow, R E -- New York, N.Y. -- Science. 1978 Jan 13;199(4325):181-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/619449" target="_blank"〉PubMed〈/a〉

    Kainic acid lesions of the striatum dissociate amphetamine and apomorphine stereotypy: similarities to Huntingdon's chorea (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-07-28
    Beschreibung: Kainic acid lesion of cell bodies in the dorsal striatum enhanced the stereotypy-producing effects of d-amphetamine without affecting the sterotypy produced by the direct receptor agonist apomorphine. This pattern of results parallels that found in patients suffering from Hungtington's chorea, thus strengthening the parallels between the kainic acid animal model and the human disease state initially suggested on biochemical gounds. The present results further suggest a dissociation of the mechanisms involved in the production of stereotypy by these two drugs, perhaps in terms of differential involvement of the striato-nigral negative feedback loop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mason, S T -- Sanberg, P R -- Fibiger, H C -- New York, N.Y. -- Science. 1978 Jul 28;201(4353):352-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26976" target="_blank"〉PubMed〈/a〉

    Generation of new mouse sarcoma viruses in cell culture (1978)

    Details
    Publikationsdatum: 1978-09-01
    Beschreibung: Endogenous nontumor-producing type C viruses from C3H mice were used to generate rapid, solid tumor-inducing variants in cell culture. The new mouse sarcoma viruses induce undifferentiated sarcomas with a short latency period upon inoculation into newborn NIH Swiss mice. Transforming viruses appear only transiently, at a time when the virus-infected cells show morphologic alterations; both before and after this time, transforming viruses cannot be detected. These results show that variants of endogenous type C virus which contain transforming genes (oncogenes) can arise during spread of the endogenous virus in fibroblast lines in vitro as well as in susceptible tissues in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rapp, U R -- Todaro, C -- New York, N.Y. -- Science. 1978 Sep 1;201(4358):821-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/210501" target="_blank"〉PubMed〈/a〉

    Potent antidopaminergic activity of estradiol at the pituitary level on prolactin release (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-06-09
    Beschreibung: Prior incubation of rat anterior pituitary cells with 17beta-estradiol led to an almost complete reversal of the inhibitory effect of two dopamine agonists, dihydroergocornine and RU 24213, on both basal prolactin release and thyrotropin releasing hormone-induced prolactin release. These experiments thus demonstrate a direct interference of dopamine action by a peripheral hormone. Prolactin secretion by pituitary cells in primary culture could possibly serve as an easily accessible model of a system under dopaminergic control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raymond, V -- Beaulieu, M -- Labrie, F -- Boissier, J -- New York, N.Y. -- Science. 1978 Jun 9;200(4346):1173-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/418505" target="_blank"〉PubMed〈/a〉

    Adrenocorticotropin in rat brain: immunocytochemical localization in cells and axons (1978)
    American Association for the Advancement of Science (AAAS)

    Publikationsdatum: 1978-06-09
    Beschreibung: By means of antiserum (purified by affinity chromatography) directed against adrenocorticotropin (ACTH) 11-24, cell bodies and beaded axons were visualized in rat brain. The ACTH-like immunoreactivity (ACTH-LI) was primarily located in the hypothalamus (cells and axons). Fibers were scattered throughout thalamus, amygdala, periaqueductal gray area, and reticular formation. There was no change in the distribution of ACTH-LI in rats that had been subjected to hypophysectomy. This distribution of ACTH-LI parallels that of beta-lipotropin and is altered by specific lesions in a similar fashion. The presence of ACTH-LI in cells and beaded axons in brain raises the possibility that it is a neuroregulator functioning as a neurotransmitter, neuromodulator, or neurohormone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, S J -- Richard, C W 3rd -- Barchas, J D -- New York, N.Y. -- Science. 1978 Jun 9;200(4346):1180-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/206967" target="_blank"〉PubMed〈/a〉

    Antibody diversity (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-10-06
    Beschreibung: Three important aspects of immunoglobulin gene organization and structure have emerged from studies of cloned immunoglobulin kappa chain genes. (i) Multiple variable genes are encoded separately in the genome of both immunoglobulin-producing and uncommitted (embryonic) cells, thereby establishing the evolutionary base for generating immunoglobulin diversity. (ii) These genes exist as many small, closely related families (subgroups) that share close sequence homology largely within their own subgroup. (iii) Comparison of two cloned variable gene segments derived from a single subgroup reveals a feature of their structure that distinguishes them from fixed genes (that is, globin genes) and provides, through extensive surrounding sequence homology, a large target for intergenic recombination. This last observation suggests that a simple recombination mechanism may account for their genetic instability in both germ line and somatic cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seidman, J G -- Leder, A -- Nau, M -- Norman, B -- Leder, P -- New York, N.Y. -- Science. 1978 Oct 6;202(4363):11-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/99815" target="_blank"〉PubMed〈/a〉

    High concentrations of glutathione in glandular stomach: possible implications for carcinogenesis (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-09-07
    Beschreibung: In laboratory rodents, concentrations of reduced glutathione (GSH) are exceedingly high (up to 7 to 8 millimolar) in the glandular gastric tissue compared to concentrations in other portions of the gastrointestinal tract or to those of most other organs. Gastric GSH varies diurnally, with the highest levels occurring in the late afternoon or early evening. Starvation, treatment with diethyl maleate, or cold-restraint stress all caused marked decreases in stomach GSH, whereas treatment with cobaltous chloride caused an increase in the GSH concentrations. The physiological significance of the high gastric GSH is unknown, but because this endogenous compound may strongly modulate (decrease or increase) the macromolecular binding of certain chemicals capable of inducing stomach tumors, the possible role of glutathione in the pathogenesis of chemically induced gastric cancer should be considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Body, S C -- Sasame, H A -- Body, M R -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1010-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/572989" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1979-04-06
    Beschreibung: Vascular casts of the pituitary gland have demonstrated a paucity of veins extending from the adenohypophysis to the systemic circulation and have suggested that some adenohypophyseal venous blood returns to the neurohypophysis. The neurohypophyseal capillary bed may function as a vascular switch and in this article a series of 14 questions are proposed regarding the vascular dynamics of the pituitary. Together these questions raise the larger question, namely, whether pituitary hormones are transported directly to the brain to modify brain function?〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bergland, R M -- Page, R B -- New York, N.Y. -- Science. 1979 Apr 6;204(4388):18-24.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/373118" target="_blank"〉PubMed〈/a〉

    Obesity genes: beneficial effects in heterozygous mice (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-02-16
    Beschreibung: The mouse mutant genes obese (ob) and diabetes (db) cause similar obesity-diabetes states in homozygotes. These obesity syndromes are characterized by a more efficient conversion of food to lipid and, once stored, a slower rate of catabolism on fasting. Heterozygous mice, either ob/+ or db/+, survived a prolonged fast significantly longer than normal homozygotes (+/+); this suggests that the heterozygotes exhibited increased metabolic efficiency, a feature normally associated with both homozygous mutants. The existence of this thriftiness trait, if manifested by heterozygous carriers in wild populations, would lend credence to the thrifty gene concept of diabetes. Beneficial effects of normally deleterious genes may have played a role in the development of diabetes-susceptible human populations, as well as having provided the survival advantage that has allowed both the development and successful establishment of species in desert and other less affluent regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coleman, D L -- New York, N.Y. -- Science. 1979 Feb 16;203(4381):663-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/760211" target="_blank"〉PubMed〈/a〉

    Beschreibung: Exposure of L1210 leukemia cells first to 0.1 to 100 micromolar methotrexate and then to 10 micromolar 5-fluorouracil produces a synergistic effect on the number of cells killed in culture. Methotrexate dose-related increases occur in the concentrations of intracellular 5-fluorouracil ribonucleotides and 5-fluoro-2'-deoxyuridylate and in the incorporation of 5-fluorouracil into RNA. These increases are correlated with increased concentrations of intracellular phosphoribosylpyrophosphate. It is proposed that the enhanced formation of ribonucleotides of 5-fluorouracil and the subsequent incorporation of these compounds into RNA in methotrexate-treated cells may account for synergism between these agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cadman, E -- Heimer, R -- Davis, L -- New York, N.Y. -- Science. 1979 Sep 14;205(4411):1135-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472732" target="_blank"〉PubMed〈/a〉

    The forebrain is not essential for sympathoadrenal hyperglycemic response to glucoprivation (1979)

    Details
    Publikationsdatum: 1979-06-08
    Beschreibung: The reduction of glycolysis by hypoglycemia or the glucose analog 2-deoxy-D-glucose (2DG) stimulates compensatory sympathetic alterations of metabolism. Considerable attention has been focused on the hypothalamus as the probable locus of requisite metabolic signal detection. We report, however, that unanesthetized chronically decerebrate rats are capable of exhibiting sympathoadrenal hyperglycemia in response to the metabolic challenge presented by 2DG. This findings demonstrates that the forebrain is not necessary for glucoprivic stimulation of this reflex. Since cervical cord transection has been shown to eliminate hyperglycemia induced by 2DG, we conclude that the caudal brainstem contains an essential part of the neural mechanism which both detects metabolic need and ameliorates that need through the release of stored fuels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DiRocco, R J -- Grill, H J -- New York, N.Y. -- Science. 1979 Jun 8;204(4397):1112-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451558" target="_blank"〉PubMed〈/a〉

    Beschreibung: Unlike normal animals or those with sham lesions, rats with hippocampal and septal lesions behaved in an operant chamber as if a dependency existed between pellet delivery and their behavior, despite the fact that reinforcement was based on time, not behavior, and was therefore free. This superstitious behavior did not result from a general inability to inhibit responding, as responding rapidly ceased when the pellets were discontinued. These findings suggest that the hippocampus integrates information regarding response-reinforcer relations, which in the normal rat permits superfluous operant behavior to be eliminated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Devenport, L D -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):721-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/462183" target="_blank"〉PubMed〈/a〉

    Beschreibung: The hypothesis was tested that an acute rise of blood pressure may reduce reactivity to noxious stimuli through a baroreceptor-mediated reduction of cerebral arousal. When blood pressure was raised by an infusion of phenylephrine, rats showed less running to terminate or avoid noxious stimuli than during saline infusions. This effect was not seen in rats with denervated baroreceptors. The results suggest that a rise of blood pressure could have motivational consequences significant for human hypertension.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dworkin, B R -- Filewich, R J -- Miller, N E -- Craigmyle, N -- Pickering, T G -- New York, N.Y. -- Science. 1979 Sep 21;205(4412):1299-301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472749" target="_blank"〉PubMed〈/a〉

    Beschreibung: The onset of maternal responsiveness by virgin female rats to foster pups was observed after (i) complete vomeronasal nerve cuts, (ii) partial olfactory bulb cuts, or (iii) the combined procedures. Although both vomeronasal nerve cuts and olfactory bulb cuts resulted in a more rapid onset of maternal care, relative to control animals with sham operations, animals sustaining the loss of both sources of olfactory input exhibited the shortest response latency. These findings are discussed in terms of the probable distinct functions of the two olfactory systems in the control of maternal behavior in the rat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fleming, A -- Vaccarino, F -- Tambosso, L -- Chee, P -- New York, N.Y. -- Science. 1979 Jan 26;203(4378):372-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/760196" target="_blank"〉PubMed〈/a〉

    Digitalis genin activity: side-group carbonyl oxygen position is a major determinant (1979)

    Details
    Publikationsdatum: 1979-08-31
    Beschreibung: The Na+,k+-adenosine triphosphatase-inhibiting activity of digitalis genins and their analogs is a function of side-group carbonyl (C = O) oxygen position. For each 2.2 angstroms that this oxygen is displaced from its position in digitoxigenin, activity drops by one order of magnitude. This quantitative relation resolves previously proposed models which have attempted to describe the molecular basis of genin activity. A multidisciplinary (crystallographic, conformational energy, synthetic, biological) approach to structure-activity relations is described.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fullerton, D S -- Yoshioka, K -- Rohrer, D C -- From, A H -- Ahmed, K -- New York, N.Y. -- Science. 1979 Aug 31;205(4409):917-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224455" target="_blank"〉PubMed〈/a〉

    Induction of copulatory behavior in sexually inactive rats by naloxine (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-04-13
    Beschreibung: The intraventricular injection of D-alanine-methionine-enkephalinamide (D-Ala2-Met-enkephalinamide), a synthetic analog of Met-enkephalin that is resistant to enzymatic degradation, inhibits copulatory behavior in sexually vigorous male rats in doses which do not influence motor activity or feeding behavior. This effect is prevented by naloxone, a specific inhibitor of opioid receptors. In addition, injections of naloxone induce copulatory behavior in sexually inactive male rats. These results suggest that endorphins play an important role in the regulation of sexual behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gessa, G L -- Paglietti, E -- Quarantotti, B P -- New York, N.Y. -- Science. 1979 Apr 13;204(4389):203-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/432642" target="_blank"〉PubMed〈/a〉

    Effect of beta-endorphin on calcium uptake in the brain (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-10-05
    Beschreibung: The uptake of 45Ca2+ by nerve-ending fractions from brains of mice was inhibited in vitro by 10(-9)M concentrations of beta-endorphin and in mice injected intraventricularly with 7 picomoles of beta-endorphin. That the effect was a specific opiate agonist response of beta-endorphin was demonstrated by use of the opiate antagonist, naloxone, which reversed the action. A role for beta-endorphin in the regulation of calcium flux and neurotransmitter release should be considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guerrero-Munoz, F -- de Lourdes Guerrero, M -- Way, E L -- Li, C H -- New York, N.Y. -- Science. 1979 Oct 5;206(4414):89-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/39340" target="_blank"〉PubMed〈/a〉

    Beschreibung: Female weanling rats from a colony maintained on a diet low in vitamin D were raised on a diet that was deficient in vitamin D but was otherwise adequate. Vitamin D deficiency was confirmed in the rats by hypocalcemia and the absence of vitamin D metabolites in blood. These females gave birth to litters that were slightly smaller than control litters from females maintained on a vitamin D-containing diet. The pups from the vitamin D-deficient mothers appeared normal throughout lactation, and at weaning had normal concentrations of calcium and phosphate in the plasma. These results indicate that vitamin D and its metabolites are not necessary for reproduction and fetal development in the rat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halloran, B P -- DeLuca, H F -- New York, N.Y. -- Science. 1979 Apr 6;204(4388):73-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/432628" target="_blank"〉PubMed〈/a〉

    Emergence of interoceptive and exteroceptive control of behavior in rats (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-08-31
    Beschreibung: The role of exteroceptive and interoceptive aversive stimuli in rats 2 to 14 days old was investigated according to an odor aversion paradigm. Amyl acetate odor was paired with eigher peripheral shock, intraperitoneal shock, or lithium chloride poisoning. Intraperitoneal shock was an effective unconditioned stimulus at all ages and produced odor aversions comparable to lithium chloride poisoning; peripheral shock, however, was effective only in rats 10 days of age or older. Interoceptive control of aversively motivated behaviors thus seems to develop before exteroceptive control, and the failure of previous studies to find reliable learning and retention of shock-motivated behaviors before 8 to 10 days of age may be attributable to the site to which shock was applied rather than to insensitivity to shock per se.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haroutunian, V -- Campbell, B A -- New York, N.Y. -- Science. 1979 Aug 31;205(4409):927-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472715" target="_blank"〉PubMed〈/a〉

The assay detects insulin binding sites at concentrations as low as 0.1 nanomolar; distinguishes between receptors originating from human placental membranes, human lymphoblastoid cells, and mouse liver membranes; and measures the receptor independently of its binding function. Down-regulation, or loss of binding after exposure to insulin, is associated with loss of immunoreactive receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, L C -- Flier, J -- Itin, A -- Kahn, C R -- Roth, J -- New York, N.Y. -- Science. 1979 Feb 9;203(4380):544-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/83675" target="_blank"〉PubMed〈/a〉

    Beschreibung: Norepinephrine reversibly antagonizes three calcium-dependent potentials recorded from rat postganglionic neurons. Norepinephrine inhibits the development of a shoulder on the aciton potential, the magnitude of the hyperpolarizing afterpotential, and the rate of rise and amplitude of the calcium spike. The action of norepinephrine is antagonized by the alpha-adrenergic antagonist phentolamine, but not by MJ 1999, a beta-adrenergic antagonist. These results suggest that activation of an alpha-adrenergic receptor may antagonize a voltage-sensitive calcium current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horn, J P -- McAfee, D A -- New York, N.Y. -- Science. 1979 Jun 15;204(4398):1233-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/221979" target="_blank"〉PubMed〈/a〉

    Methylazoxymethanol treatment of fetal rats results in abnormally dense noradrenergic innervation of neocortex (1979)

    Details
    Publikationsdatum: 1979-01-26
    Beschreibung: A single injection of methylazoxymethanol in pregnant rats at 15 days of gestation results in severe cortical atrophy in the offspring. In the adult offspring, the neurochemical markers for the cortical gamma-aminobutyric acid-containing neurons are severely reduced, whereas the noradrenergic markers are minimally altered. Immunohistofluorescence microscopy demonstrates a marked increase in the density of noradrenergic axons which have an abnormal pattern of distribution in the atrophic cortex. The results suggest that the central noradrenergic neurons determine the number of axons to be formed early in brain development, but local factors in the terminal field regulate the ultimate distribution of the noradrenergic axons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnston, M V -- Grzanna, R -- Coyle, J T -- New York, N.Y. -- Science. 1979 Jan 26;203(4378):369-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/32620" target="_blank"〉PubMed〈/a〉

    Genetic mechanism accounting for precise immunoglobulin domain deletion in a variant of MPC 11 myeloma cells (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-12-14
    Beschreibung: A variant of the MPC 11 cell line, M 311, produces a short immunoglobulin heavy chain. When compared with the parental gamma 2b heavy chain, M 311 was found to have a carboxyl terminal deletion comprising the CH3 domain. The COOH-terminal cyanogen bromide (CNBr) cleavage fragment of M 311 is identical to a corresponding segment ofa parental heavy chain CNBr fragment, with the exception of a substitution of asparagine for lysine at the COOH-terminal residue. This observation enabled prediction of both the parental DNA sequence in this region and the genetic mechanism which generated the variant, a frameshift followed by premature termination. This hypothesis is supported by studies of the DNA sequence of the MPC 11 gamma 2b constant region gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kenter, A L -- Birshtein, B K -- R21 AI106328/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1307-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/117550" target="_blank"〉PubMed〈/a〉

At a low concentration (1 microgram per milliliter), erythrosin B (FD&C red 3) was the only dye that inhibited dopamine accumulation.

    Inosine may be an endogenous ligand for benzodiazepine receptors on cultured spinal neurons (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-08-17
    Beschreibung: Mouse spinal neurons grown in tissue culture were used to study the membrane effects of the benzodiazepine flurazepam and the naturally occurring purine nucleoside inosine, which competes for benzodiazepine receptor sites in the central nervous system. Application of inosine elicited two types of transmitter-like membrane effects: a rapidly desensitizing excitatory response and a nondesensitizing inhibitory response. Flurazepam produced a similar excitatory response which showed cross-desensitization with the purine excitation. Flurazepam also blocked the inhibitory inosine response. The results provide electrophysiological evidence that an endogenous purine can activate two different conductances on spinal neurons and that flurazepam can activate one of the conductances and antagonize the other.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacDonald, J F -- Barker, J L -- Paul, S M -- Marangos, P J -- Skolnick, P -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):715-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/37602" target="_blank"〉PubMed〈/a〉

    Hippocampal afterdischarges: differential spread of activity shown by the [14C]deoxyglucose technique (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-05-11
    Beschreibung: Differential spread of afterdischarge activity initiated electrically in ventral and dorsal parts of the hippocampal formation was studied by the [14C]deoxyglucose technique in rats. Afterdischarges initiated in either the ventral or dorsal hippocampal formation, without activation of the ventral subicular cortex, increased glucose utilization in the lateral septum. In contrast, afterdischarges initiated by direct activation of the ventral subicular cortex increased glucose utilization in extensive areas of the ipsilateral amygdala, claustrum, hypothalamus, preoptic region, and basal forebrain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kliot, M -- Poletti, C E -- New York, N.Y. -- Science. 1979 May 11;204(4393):641-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/432672" target="_blank"〉PubMed〈/a〉

    Intercellular communication in pancreatic islet monolayer cultures: a microfluorometric study (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-05-25
    Beschreibung: Single islet cells in monolayer cultures of neonatal rat pancreas were microinjected with fluorescein and scanned topographically by microfluorometry. Fluorescein spread from an injected islet cell directly into neighboring islet cells, and, in the presence of 16.7 millimolar glucose, significantly more islet cells communicated with the injected cell than in glucose-free medium. Islet cells were also microinjected with glycolytic substrates and activators that produced transient changes in cellular levels of reduced pyridine nucleotides-nicotinamide adenine dinucleotide and nicotinamide adenine dinucleotide phosphate [NAD(P)H]. Changes in NAD(P)H fluorescence were observed in islet cells incubated first for 18 hours in very low glucose concentrations and then in a glucose-free medium and injected with glycolytic substrates and activators; however, little change of fluorescence occurred in adjacent islet cells. In contrast, after adding 16.7 millimolar glucose to the medium, injection of glycolytic substrates and activators produced transient changes in NAD(P)H fluorescence in the injected cell and in neighboring cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kohen, E -- Kohen, C -- Thorell, B -- Mintz, D H -- Rabinovitch, A -- New York, N.Y. -- Science. 1979 May 25;204(4395):862-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/35828" target="_blank"〉PubMed〈/a〉

    Genetic mapping of the ecotropic murine leukemia virus-inducing locus of BALB/c mouse to chromosome 5 (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-04-06
    Beschreibung: By means of an approach that combined the techniques of somatic cell genetics and Mendelian breeding studies, the inducibility locus, designated Cv, for ecotropic murine leukemia virus in BALB/c mice, was mapped to chromosome 5, 23 units from the locus for phosphoglucomutase-1, with gene order Cv-Pgm-1-Gus. This low-efficiency inducibility locus is therefore not allelic with the chromosome 7 loci previously described for two other mouse strains with high virus inducibility. These studies provide further evidence that endogenous ecotropic viruses represent viral genomes inserted at different chromosomal sites in the various mouse strains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kozak, C A -- Rowe, W P -- New York, N.Y. -- Science. 1979 Apr 6;204(4388):69-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/219475" target="_blank"〉PubMed〈/a〉

    Movement disorders of aged rats: reversal by dopamine receptor stimulation (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-10-26
    Beschreibung: When placed in a tank of water, aged rats (24 to 27 months old) showed marked impairments in swimming. Compared with young adult rats (3 to 4 months old), the older animals moved their limbs less vigorously and were less successful in keeping their heads above water. The young, but not old, rats maintained a position nearly horizontal to the water surface and planed across it. These movement dysfunctions of aged rats resemble those seen in young adult animals that have sustained injury to brain dopamine-containing neurons. The swimming impairments of the aged rats were reversed by the dopamine receptor stimulant apomorphine and by the biosynthetic precursor of dopamine, L-dopa. Thus, age-related alterations in brain dopaminergic systems may be responsible for some of the movement disturbances associated with senescence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marshall, J F -- Berrios, N -- New York, N.Y. -- Science. 1979 Oct 26;206(4417):477-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/504992" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mice with the mutant gene tottering (tg, chromosome 8, autosomal recessive) show, in adolescence, abnormal bursts of bilaterally synchronous spike waves as revealed in electrocorticograms recorded over long periods. The spike waves are accompanied by behavioral "absence" attacks and intermittent focal motor seizures showing somatotopic progression. Cerebral metabolic activity during seizures was assayed by autoradiography of brain sections from mice injected intravenously with 14C-labeled 2-deoxyglucose. Metabolic activity was increased bilaterally in selected brainstem structures. Spontaneous electrocorticographic and clinical seizures of this general pattern were recognized hitherto only in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noebels, J L -- Sidman, R L -- New York, N.Y. -- Science. 1979 Jun 22;204(4399):1334-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/572084" target="_blank"〉PubMed〈/a〉

    Endogenous inhibitor of colchicine-tubulin binding in rat brain (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-08-10
    Beschreibung: A competitive inhibitor of colchicine binding to tubulin has been found in rat brain. Most of the inhibitor is associated with microsomes but some inhibitor, with an apparent molecular weight of approximately 250,000, is found in the cytosol. Both the microsomal and cytosol inhibitors are heat- and trypsin-sensitive, indicating that a protein moiety is required for activity. The microsomes bind tubulin directly; the microsomal and cytosol fractions both inhibit microtubule assembly in vitro. The inhibitor may function in the living cell to bind and sequester non-polymerized tubulin. Regulation of tubulin attachment to microsomes could then control the concentration of cytosolic tubulin available for microtubule assembly.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sherline, P -- Schiavone, K -- Brocato, S -- New York, N.Y. -- Science. 1979 Aug 10;205(4406):593-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451622" target="_blank"〉PubMed〈/a〉

However, Hpa II cuts mouse liver DNA to fragments four times larger than does Msp I. The size of DNA cut by Msp I is close to that predicted from base composition and nearest neighbor analysis.

    Dynamic changes in circulating 1,25-dihydroxyvitamin D during reproduction in rats (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-06-29
    Beschreibung: The concentrations of 1,25-dihydroxyvitamin D [1,25-(OH)2D], calcium, and phosphorus were measured in the serum of rats during pregnancy and at various stages of lactation. The concentration of 1,25-(OH)2D hormone increased almost two-fold during pregnancy and the latter part of lactation, but decreased to control levels or very low values immediately after birth and weaning, respectively. Furthermore, the concentration of 1,25-(OH)2D was inversely correlated with the concentration of calcium, suggesting that circulating 1,25-(OH)2D fluctuates in concert with calcium demands during the reproductive cycle. Parathyroidectomy in lactating rats caused a 70 percent inhibition of the normally observed 1,25-(OH)2D increase, indicating that parathyroid hormone, in response to changes in serum calcium, is a primary modulator of 1,25-(OH)2D during lactation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pike, J W -- Parker, J B -- Haussler, M R -- Boass, A -- Toverud, S V -- New York, N.Y. -- Science. 1979 Jun 29;204(4400):1427-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451573" target="_blank"〉PubMed〈/a〉

    Beschreibung: After mature rats that had been fed on a vitamin D3-deficient diet were injected with tritium-labeled 1,25-dihydroxyvitamin D3, radioactivity became concentrated in nuclei of luminal and cryptal epithelium of the duodenum, jejunum, ileum, and colon; in nuclei of the epithelium of kidney distal tubules including the macula densa, and in podocytes of glomeruli; in nuclei of the epidermis including outer hairshafts and sebaceous glands; and in nuclei of certain cells of the stomach, anterior and posterior pituitary, and parathyroid. These results reveal cell types that contain receptors for 1,25-dihydroxyvitamin D3 or metabolites of this compound both in known or hypothesized target tissues and in tissues that were previously unknown to participate in vitamin D3 metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stumpf, W E -- Sar, M -- Reid, F A -- Tanaka, Y -- DeLuca, H F -- New York, N.Y. -- Science. 1979 Dec 7;206(4423):1188-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/505004" target="_blank"〉PubMed〈/a〉

    Microwave radiation and chlordiazepoxide: synergistic effects on fixed-interval behavior (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-03-30
    Beschreibung: In the presence of low-intensity pulsed microwave radiation, at an average power density of 1 milliwatt per square centimeter, the response-rate-increasing effects of chlordiazepoxide were potentiated in rats. The behavioral effects of a drug can be modified by brief exposure to a low-level microwave field even when the radiation level alone has no apparent effects on the behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thomas, J R -- Burch, L S -- Yeandle, S S -- New York, N.Y. -- Science. 1979 Mar 30;203(4387):1357-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424759" target="_blank"〉PubMed〈/a〉

    Iron deficiency prevents liver toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-04-20
    Beschreibung: The compound 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes hepatocellular damage and porphyria in C57B1/6J mice, among a wide range of toxic effects. We compared the effect of TCDD toxicity in iron-deficient mice with that in mice receiving a normal diet. Porphyria did not develop in the iron-deficient animals, and these animals were also protected from hepatocellular damage and certain other toxic effects of TCDD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sweeny, G D -- Jones, K G -- Cole, F M -- Basford, D -- Krestynski, F -- New York, N.Y. -- Science. 1979 Apr 20;204(4390):332-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/432648" target="_blank"〉PubMed〈/a〉

    Structure of the constant and 3' untranslated regions of the murine gamma 2b heavy chain messenger RNA (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-12-14
    Beschreibung: The complete coding sequence for the constant region of the mouse gamma 2b immunoglobulin heavy chain and the 3' untranslated region has been determined. The coding portion of the sequence is 1008 nucleotides long (amino acid residues 114 to 449), and the 3' noncoding region contains 102 nucleotides preceeding the polyadenylate. An extra carboxyl-terminal lysine residue which had not been observed in the gamma 2b or other gamma subclass protein sequences occurs in the nucleotide sequence and is probably processed posttranslationally. A 17-nucleotide sequence occurs with slight variation twice in CH1 and once in CH2 domains in the same relative location but with different translational phase. This sequence may be the site of crossover in a gamma 2b . gamma 2a heavy chain variant, an indication of possible recombinational activity of some kind.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tucker, P W -- Marcu, K B -- Slightom, J L -- Blattner, F R -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1299-303.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/117548" target="_blank"〉PubMed〈/a〉

    Beschreibung: The decrease in resting oxygen consumption induced by starvation was found to occur not only in euthyroid rats but also in hypothyroid and even in hypothyroid animals treated with triiodothyronine. Furthermore, the effectiveness of triiodothyronine was decreased when given to hypothyroid animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wimpfheimer, C -- Saville, E -- Voirol, M J -- Danforth, E Jr -- Burger, A G -- New York, N.Y. -- Science. 1979 Sep 21;205(4412):1272-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224460" target="_blank"〉PubMed〈/a〉

    Distribution of nitrogen-13 from labeled nitrate (13No3-) in humans and rats (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-04-27
    Beschreibung: The body distribution of gavaged or intravenously administered nitrate labeled with nitrogen-13 was studied in humans and rats with the following results: (i) the labeled compound is not quickly absorbed from the stomach; (ii) the concentration of the label increases inside the lower intestinal tract (cercum and large intestine) when ingested or intravenously injected; and (iii) humans and rats have the capacity to store a portion of the label in their bodies. These observation indicate that depletion of body stores, the passage of nitrate down the gut, or the secretion of nitrate into the intestinal lumen may be a better explanation of the urinary, ileal, and fecal concentrations of nitrate and nitrite recently measured in humans that a bacterial nitrification reaction in the intestines, as suggested by Tannenbbaum et al.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Witter, J P -- Gatley, S J -- Balish, E -- New York, N.Y. -- Science. 1979 Apr 27;204(4391):411-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/441728" target="_blank"〉PubMed〈/a〉
