    Description / Table of Contents: Zusammenfassung Die Kinetik der Oxidation von Allylalkohol mitN-Bromsuccinimid (NBS) wurde bei 35 °C in wäßrigem Medium untersucht. Die Reaktion zeigt erste Ordnung gegenüberNBS und Allylalkohol. Bei relativ hoher Säurekonzentration zeigt sich keine Änderung der Reaktionsgeschwindigkeit, bei niedriger Säurekonzentration wird die Reaktionsgeschwindigkeit beträchtlich erhöht. Es wurde kein primärer Salzeffekt festgestellt. Bei varriierender Quecksilberacetatkonzentration bleibt die Reaktionsgeschwindigkeit gleich, bei Abwesenheit von Quecksilberacetat wird jedoch die Geschwindigkeitskonstante erhöht. Die kinetischen Parameter,E a, derArrheniusfaktorA, ΔH ≠, ΔG ≠ und ΔS ≠ wurden bestimmt. Ein Geschwindigkeitsgesetz in Übereinstimmung mit den experimentellen Befunden wurde abgeleitet und ein Mechanismus vorgeschlagen.
    Notes: Abstract The kinetics of oxidation of allyl alcohol byN-bromosuccinimide (NBS) has been studied at 35 °C in aqueous medium. The reaction shows first order dependence on bothNBS and allyl alcohol. In fairly high acid concentration, there is no change in the rate of the reaction but at low acid concentration, the rate is considerably enhanced. There is no primary salt effect. At varying mercuric acetate concentrations, the rate constant remains the same. But in the absence of mercuric acetate, the rate is enhanced. The kinetic parameters,E a,Arrhenius factorA, ΔH≠, ΔG≠ and ΔS≠ have been calculated. A rate law in agreement with experimental results has been derived. A mechanism is proposed.

    Description / Table of Contents: Zusammenfassung Die Reduktion von Thoriumoxid mit Graphit im Überschuß wurde mittels einer Thermowaage zwischen 1620 und 1920 K im Vakuum untersucht. Ab ThO2:C=1:50 war die Reaktionsgeschwindigkeit vom Mischungsverhältnis unabhängig; das Endprodukt war immer ThC2. Der logarithmische Gewichtsverlust war direkt proportional der Zeit, und dieArrheniusgerade zeigte einen Knickpunkt bei 1710 K: unterhalb dieser Temperatur ergab sich eine Aktivierungsenergie von 440 kJ, oberhalb eine solche von 260 kJ. Die Temperatur des Knickpunkts entspricht der Umwandlungstemperatur von monoklinem in tetragonal raumzentriertes ThC2.
    Notes: Abstract The reduction of thoria with excess graphite was studied with a thermo-balance in vacuum between 1620 and 1920 K. From Th02:C=1:50 the rate of reaction was independent of the ratio of the reactants; the endproduct was always ThC2. The logarithmic weight loss was directly proportional to the time, and theArrhenius plot showed a break at 1710 K: below this temperature the activation energy was found to be 440 kJ, above 260 kJ. The temperature corresponding to the break coincides with the transition temperature of monoclinic to body-centered tetragonal ThC2.

    Notes: Abstract The transfer of oxinate ions from thallium (III)oxinate to trivalent Fe(DMF) 6 3+ in propylenecarbonate takes place via rearrangements within a rapidly formed binuclear thallium(III)—iron(III) complex. In a last rapid step this rearranged complex reacts with excess reactants to the final products whose composition accordingly depends on the ratio of the reactant concentrations.

    Notes: Summary Parathyroid hormone (PTH) metabolism in pregnancy has not been clearly defined. Studies have reported either increased or unchanged values of immunoreactive PTH (iPTH). However, iPTH levels do not necessarily correlate with hormonal bioactivity due to the presence of immunoreactive but nonbioactive PTH fragments. In this study we evaluated PTH metabolism in the third trimester of pregnancy by determining iPTH blood levels as well as the biological effects of PTH, assessed by tubular maximum phosphate reabsorption (TmP) and nephrogenous cAMP (ncAMP) excretion, in 10 young, healthy pregnant patients (mean gestational age 35 weeks) and 10 young, healthy age-matched female controls. Pregnancy was associated with a significant increase in creatinine clearance (146±13 vs 106±9 ml/min,P〈0.01), and a significant decrease in total fasting serum calcium (8.4±0.1 vs 9.0±0.1 mg/dl,P〈0.001) and serum albumin (3.6±0.1 vs 4.2±0.1 g/dl,P〈0.001). There was no significant difference in iPTH (3.7±0.4 vs 4.3±0.5 µlEq/ml), serum phosphorus (3.6±0.1 vs 3.8±0.2 mg/dl), TmP (3.61±0.13 vs 3.75±0.25 mg/100 ml GFR), or ncAMP (1.68±0.20 vs 1.88±0.23 nmoles/100 ml GFR) between the two groups. Pregnancy was attended by a significant increase in fasting urinary calcium to creatinine ratio (0.14±0.03 vs 0.06±0.01,P〈0.05), an index of bone resorption. The data suggest that the biological effects of PTH are unchanged in pregnancy, and that reported increments in 1,25(OH)2 vitamin D in pregnancy are not regulated by changes in either PTH, calcium, or phosphate.

    Notes: Summary The effect of vitamin D on bone changes during the reproductive cycle in female rats has been investigated. One group of female rats was maintained on a vitamin D-deficient diet and another group on a vitamin D-replete diet from weaning. Both groups were mated with normal males and changes in their bones were determined histomorphometrically during pregnancy, lactation, and after weaning. All vitamin D-deficient rats had bone changes typical of rickets. Pregnancy caused significant reductions in mineralized tissue of trabecular and cortical bone in the vitamin D-deficient rats. Lactation caused further significant reductions in mineralized tissues of cortical and trabecular bone in both the vitamin D-deficient and vitamin D-replete animals, with the greatest changes seen at weaning. Some restoration of mineralized tissues occurred following weaning. There was an increase in tetracycline-labeled bone surface in the vitamin D-replete animals during lactation, likely due to an increase in bone formation rates. In the vitamin D-deficient animals during lactation, there was a decrease in tetracyclinelabeled bone surface, likely due to severely depressed bone mineralization. These results indicate that the mobilization of calcium from bone to maintain pregnancy and lactation occurs by a mechanism independent of vitamin D.

    Notes: Summary The sensitivity of the mineralization of nitrogen by a range of soils contaminated with heavy metals (up to 340 μg Cd g−1, 7500 μg Pb g−1 and 34000 μg Zn g−1) to the addition of heavy metals in solution were studied using pot incubations (ammonification) and a soil perfusion technique (nitrification). The ammonification of peptone showed little correlation between treatments with Cd, Zn (1000 and 5000 μg g−1) and Pb (10000 and 20000 μg g−1) and origin of the soil. Nitrification was considerably more sensitive to heavy metals than ammonification. All the soils had active, often large, populations of ammonifying and nitrifying organisms which showed substantial similarities between the soils. The rate of nitrifying activity (NO3−N production) was logrithmic in most cases. The presence of tolerant populations of nitrifying organisms in the contaminated soils was demonstrated. Tolerance was also eventually acquired after a longer lag phase, by the non-contaminated soil populations although the rate of activity was often reduced. Metals added in solution were adsorbed by the soil within 4 hours. Differences in toxicity between metal salts (chlorides, sulphates and acetate) were attributed to the amount left in solution. However, in many instances, acetate was found to stimulate all the stages in the mineralisation of nitrogen.

    Notes: Summary The ultrastructure of tight junctions between uterine luminal epithelial cells of the pregnant rat was studied by the freeze-fracture technique. On day 5 of pregnancy, the day of implantation, the region of tight junctions extended three times as far down the lateral cell membrane as on day 1 of pregnancy, and the strands of the complex interlinked more frequently. These observations suggest that tight junctions on day 5 may be more efficient in preserving the contents of the uterine lumen from dilution or escape than at earlier times of pregnancy.

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

    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〉

    Description: Female athymic nude mice and their phenotypically normal littermates were exposed transplacentally to ethylnitrosourea. Skin tumors (papillomas and sebaceous adenomas) developed on the nude mice with an almost tenfold greater incidence than on their haired littermates. Skin tumors were also induced on nude mice but not haired controls by direct intraperitoneal treatment with ethylnitrosourea. These results indicate that nude mice have higher than normal susceptibility to carcinogenesis under some circumstances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, L M -- Last-Barney, K -- Budinger, J M -- CA 08748/CA/NCI NIH HHS/ -- CA 22498/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 12;218(4573):682-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7134965" target="_blank"〉PubMed〈/a〉

    Description: A method has been developed for the measurement of intracellular free calcium in mammalian cells. The calcium-sensitive photoprotein aequorin can be incorporated into isolated cells by hypo-osmotic treatment without altering the cell viability, permeability, or metabolism. Intracellular calcium activity (Cai2+) was monitored in a perfusion system. In monkey kidney cells (LLC-MK2), Cai2+ is approximately 57 nanomoles per liter. Changes in Cai2+ with time can also be followed: exposure of the cells to anaerobiosis or the calcium ionophore A23187 reversibly increases Cai2+. The method has also been successfully tested in rat hepatocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Borle, A B -- Snowdowne, K W -- New York, N.Y. -- Science. 1982 Jul 16;217(4556):252-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6806904" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Simple chemical catalysts have been designed to achieve some desirable features of enzymes. These novel catalysts are not proteins, but they may incorporate the typical enzyme catalytic groups and they achieve selectivity in their reactions by use of geometric control, as do enzymes. Catalysts that carry out geometrically controlled chlorinations of aromatic rings and steroids have been constructed. Other catalysts achieve the selective synthesis of amino acids, and still others imitate ribonuclease in detailed mechanism and hydrolyze RNA. Optimization of geometries has led to a rate acceleration of over 10(8) in one instance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breslow, R -- New York, N.Y. -- Science. 1982 Nov 5;218(4572):532-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123255" target="_blank"〉PubMed〈/a〉

    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〉

    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〉

    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〉

    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〉

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

    Description: Mouse embryos were grown successfully in vitro from the blastocyst stage to the limb bud stage. Mouse blastocysts grown in vitro for 10 days showed blood circulation in the yilk sac, forelimb buds, and the primordia of liver, pancreas, and lungs. These characteristics are indicative of a developmental stage equivalent to one-half of the total gestation period in utero. Improvements in culture conditions from days 7 to 9 have made it feasible to culture mouse blastocysts beyond the early somite stage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, L T -- Hsu, Y C -- AM 19535/AM/NIADDK NIH HHS/ -- AM 28550/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 1;218(4567):66-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123220" target="_blank"〉PubMed〈/a〉

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

    Description: Studies of isolated islets labeled with radioactive leucine show that glucose at a critical time "marks" islets in such a way as to cause preferential release of newly synthesized insulin. The preferential release of insulin from marked islets is relatively independent of subsequent secretagogues or rates of insulin secretion. Previous kinetic studies have indicated that the critical time at which marking occurs is after proinsulin biosynthesis but before the secretory event. Thus, secretory cells may regulate the diversion of newly synthesized material for immediate release as it is approaching or transiting the Golgi apparatus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gold, G -- Gishizky, M L -- Grodsky, G M -- AM 01410/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 1;218(4567):56-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6181562" target="_blank"〉PubMed〈/a〉

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

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

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

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

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

    Description: Administration of the hepatic carcinogen aflatoxin B1 to experimental animals results in covalent binding to liver mitochondrial DNA at concentrations three to four times higher than nuclear DNA. The concentration of carcinogen adducts in mitochondrial DNA remains unchanged even after 24 hours, possible because of lack of excision repair. Similarly, mitochondrial transcription and translation remain inhibited up to 24 hours suggesting long-term effects of aflatoxin B1 on the mitochondrial genetic system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Niranjan, B G -- Bhat, N K -- Avadhani, N G -- CA-22762/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 1;215(4528):73-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6797067" target="_blank"〉PubMed〈/a〉

    Description: A cavity was made in the brain (entorhinal cortex) of developing or adult rats, and a small piece of Gelfoam was emplaced to collect fluid secreted into the wound. The neuronotrophic activity of the fluid was assayed with sympathetic and parasympathetic neurons in culture. The results show that wounds in the brain of developing or adult rats stimulate the accumulation of neuronotrophic factors and that the activity of these factors increases over the first few days after infliction of the damage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nieto-Sampedro, M -- Lewis, E R -- Cotman, C W -- Manthorpe, M -- Skaper, S D -- Barbin, G -- Longo, F M -- Varon, S -- AG-00538/AG/NIA NIH HHS/ -- MH-19691/MH/NIMH NIH HHS/ -- NS-16349/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):860-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100931" 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〉

    Description: Norethisterone (17 alpha-ethynyl-19-nortestosterone) is an effective irreversible inhibitor of estrogen synthetase (aromatase), the enzyme responsible for the conversion of androgens to estrogens, even at a 2 X 10(-6) molar concentration. This irreversible inactivation, which is directed toward the active site of aromatase and requires the cofactor-reduced nicotinamide adenine dinucleotide phosphate, is both time- and concentration-dependent. Ethisterone (17 alpha-ethynyltestosterone), in contrast, is not a suicide inhibitor of aromatase even at concentrations of 10(-4) molar.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Osawa, Y -- Yarborough, C -- HDO4945/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 5;215(4537):1249-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058343" target="_blank"〉PubMed〈/a〉

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

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

    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〉

    Description: Spectral analysis of spontaneous fluctuations in human fetal movement revealed strong oscillations at frequencies between 0.24 and 0.90 cycle per minute, which are much higher than those of the cyclic alternation of quiet and active states in the fetus and neonate. Oscillations at frequencies up to 2.88 cycles per minute were also detected, but they were usually much weaker. The prominent peaks in the fetal movement spectra are in the frequency range of recently reported neonatal motor rhythms, and indicate the existence of a cyclic process controlling spontaneous motor output that oscillates near one cycle per minute and begins to function in utero.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robertson, S S -- Dierker, L J -- Sorokin, Y -- Rosen, M G -- M01RR00210/RR/NCRR NIH HHS/ -- P50HD11089/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1327-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146916" target="_blank"〉PubMed〈/a〉

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

    Description: Mice infected with Trypanosoma rhodesiense were treatment concurrently with cis-diamminedichloroplatinum (II) (DDP), disulfiram, and hydration. Most of the mice (92.5 percent) were cured; inoculation of blood or suspensions of brain or heart from these animals did not produce disease in recipient mice. The dose of DDP needed to eliminate the trypanosomes, 3 milligrams per kilogram of body weight per day for 7 days, was lethally toxic unless the animals received disulfiram orally and subcutaneous injections of physiologic saline, which reduced the acute renal necrosis caused by DDP alone.

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: Previous studies have indicated that there is a relation between testicular function and adequate concentrations of zinc in testicular cells, and that calcitonin alters cellular zinc transfer in the testis. The present studies provide autoradiographic evidence that calcitonin binds in vivo to the cell membrane of testicular Leydig cells. The data thus confirm the presence of the testicular cell membrane calcitonin receptors that were previously demonstrated indirectly by Scatchard analysis of data collected from binding studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chausmer, A B -- Stevens, M D -- Severn, C -- New York, N.Y. -- Science. 1982 May 14;216(4547):735-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6281881" target="_blank"〉PubMed〈/a〉

    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〉

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

    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〉

    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〉

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

    Description: The oligonucleotide (2'-5') oligoadenylate that is induced in interferon-treated animal cells protects plant tissue from infection by the tobacco mosaic virus. This inhibition of virus multiplication was obtained at concentrations comparable to those affecting protein synthesis and antiviral activities in animal cells. After treatment with (2'-5') oligoadenylate, the multiplicability of tobacco mosaic virus was reduced by 80 to 90 percent as measured by enzyme-linked immunosorbent assay. These results, along with the observation that human interferon protects tobacco tissue from infection by tobacco mosaic virus, indicate that plants and animals may have a common pathway for virus resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Devash, Y -- Biggs, S -- Sela, I -- New York, N.Y. -- Science. 1982 Jun 25;216(4553):1415-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178155" target="_blank"〉PubMed〈/a〉

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

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

    Description: The concentration of oxytocin receptors increased in the myometrium of pregnant women and reached maximum levels in early labor. Concentrations of oxytocin receptors were also high in the decidua and reached a maximum at parturition. In vitro, prostaglandin production by the decidua, but not by the myometrium, was increased by the addition of oxytocin. Oxytocin may therefore stimulate uterine contractions by acting both directly on the myometrium and indirectly on decidual prostaglandin production. Oxytocin receptors are probably crucial for the onset of human labor, and the stimulus for the increase in uterine prostaglandins may be oxytocin originating from the fetus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fuchs, A R -- Fuchs, F -- Husslein, P -- Soloff, M S -- Fernstrom, M J -- HD8406/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 12;215(4538):1396-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6278592" target="_blank"〉PubMed〈/a〉

    Description: The activity of a cystine transport system in lysosomes prepared from the leukocytes of patients with cystinosis was found to be deficient. In normal subjects, this system was resistant to N-ethylmaleimide and demonstrated saturation kinetics. Lysosomes from individuals heterozygous for cystinosis demonstrated a reduced maximum velocity for cystine egress from lysosomes. The rate of cystine escape from normal lysosomes was enhanced by adenosine triphosphate. The availability of normal and mutant lysosomes provides a means of investigating mechanisms of amino acid transport across lysosomal membranes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gahl, W A -- Bashan, N -- Tietze, F -- Bernardini, I -- Schulman, J D -- New York, N.Y. -- Science. 1982 Sep 24;217(4566):1263-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112129" target="_blank"〉PubMed〈/a〉

    Description: Male Thamnophis melanogaster court immediately when exposed to estrogen-treated, attractive females and continue courting for 6 to 8 days. Males exposed to estrogen-treated females will court both intact and ovariectomized females. These males undergo a period of testicular recrudescence, whereas males exposed only to ovariectomized females do no. Sexual attractivity can be induced in female T. melanogaster without estrogen treatment by heavy feeding, which results in significant increases in liver size and activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garstka, W R -- NICHHDHD 12709/HD/NICHD NIH HHS/ -- NIMH 1 KOZ MH 00135/MH/NIMH NIH HHS/ -- NINCDS 15305/DS/DS NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 17;217(4565):1159-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7202252" target="_blank"〉PubMed〈/a〉

    Description: In paraplegics and quadriplegics a profound paralysis of skeletal muscles occurs below the level of the spinal lesion. Unexplained in this state is the development of an overactive external urethral sphincter, which interferes with emptying of the bladder and may lead to infection of the urinary tract.

    Description: The biosynthesis of melanin is initiated by the catalytic oxidation of tyrosine to dopa by tyrosinase in a reaction that requires dopa as a cofactor. Tyrosine then catalyzes the dehydrogenation of dopa to dopaquinone. The subsequent reactions can proceed spontaneously in vitro. Tyrosinase, purified from murine melanomas and the skins of brown mice, has now been shown to catalyze a third reaction in mammalian melanogenesis, namely the conversion of 5,6-dihydroxyindile to melanochrome. This reaction requires dopa as a cofactor and is inhibited by tyrosine. Conversely, 5,6-dihydroxyindole inhibits the oxidation of tyrosine to dopa, so that the relative concentrations of tyrosine and 5,6-dihydroxyindole within the mammalian pigment cell are capable of regulating melanogenesis in a previously unrecognized fashion. Tyrosinase has the unusual property of catalyzing three distinct reactions within a single biochemical pathway: the hydroxylation of a monophenol, the dehydrogenation of a catechol, and the dehydrogenation of a dihydroxyindole. The first and third of these reactions require dopa as a cofactor; in the second reaction, dopa is a substrate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korner, A -- Pawelek, J -- DA-01147/DA/NIDA NIH HHS/ -- DA-05186/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 17;217(4565):1163-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6810464" target="_blank"〉PubMed〈/a〉

    Description: Intraperitoneal injections of antibodies to pancreatic glucagon at the onset of the first meal after 12 hours of food deprivation increased meal size 63 percent and meal duration 74 percent in rats. The antibodies also reduced the increase in hepatic vein blood glucose that occurred during meals in control rats, but did not affect the prandial increase in portal vein blood glucose. These results suggest that, under these conditions, pancreatic glucagon is necessary for the normal termination of meals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Langhans, W -- Zeiger, U -- Scharrer, E -- Geary, N -- New York, N.Y. -- Science. 1982 Nov 26;218(4575):894-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7134979" target="_blank"〉PubMed〈/a〉

On days 7 and 35, they were given intramuscular injections of the benzodiazepine receptor antagonist Ro 15-1788. Mild and intermediate withdrawal signs, including retching and vomiting, were observed after 7 days of diazepam, and more frequent and intense withdrawal signs, including tremor and convulsion, occurred after 35 days of diazepam. With the termination of the diazepam injections after 45 days, a mild to intermediate withdrawal syndrome was observed over the next 15-day period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lukas, S E -- Griffiths, R R -- DA-01147/DA/NIDA NIH HHS/ -- DA-05186/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 17;217(4565):1161-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6287579" target="_blank"〉PubMed〈/a〉

    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〉

    Description: An enzyme purified from squid nerve that hydrolyzes the cholinesterase inhibitor diisopropyl phosphorofluoridate (DFP) has now been coupled to agarose beads. A column of this agarose-DFPase hydrolyzes the nerve gas 1,2,2-trimethylpropyl methylphosphonofluoridate (Soman). Although the more inhibitory of the four diastereoisomers of Soman are hydrolyzed least rapidly, a column of sufficient length will accomplish 95 percent hydrolysis whether measured by fluoride release or loss of cholinesterase-inhibiting power. The results suggest a means for detoxifying unwanted chemical warfare agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoskin, F C -- Roush, A H -- ES-02116/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 5;215(4537):1255-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058344" target="_blank"〉PubMed〈/a〉

    Description: The effect of light on the polypeptide map profile of the Drosophila eye preparation was examined by two-dimensional polyacrylamide gel electrophoresis. The results show (i) that illuminating the living fly reversibly changes the isoelectric points of three classes of polypeptides specific for the photoreceptor layer and (ii) that the norpA mutation, which prevents the generation of the receptor potential, blocks the modifications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsumoto, H -- O'Tousa, J E -- Pak, W L -- EY 00033/EY/NEI NIH HHS/ -- EY 07008/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):839-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100927" target="_blank"〉PubMed〈/a〉

    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〉
