    Auditory brainstem frequency following responses to waveform envelope periodicity (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-21
    Description: An auditory frequency following response (FFR) was recorded to four complx stimuli. The FFR corresponded to the waveform envelope periodicity but not to the "missing fundamental" pitch of the stimuli. The FFR may be significant for timbre perception and sound lateralization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, J W 3rd -- New York, N.Y. -- Science. 1979 Sep 21;205(4412):1297-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472748" target="_blank"〉PubMed〈/a〉

    Hormone changes triggered by aggression in a natural population of blackbirds (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-03-02
    Description: The concentrations of hormones in the plasma of male red-winged blackbirds caught at the height of an aggressive encounter are significantly different from those in males that have not recently engaged in aggressive behavior. Concentrations of luteinizing hormone in the plasma are decreased in the aggressive males, whereas androgen concentrations are affected in a more complex manner. Concentrations of corticoids do not appear to be affected by aggressive behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harding, C F -- Follett, B K -- New York, N.Y. -- Science. 1979 Mar 2;203(4383):918-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/570304" target="_blank"〉PubMed〈/a〉

    Angiotensin convertase activities in human alveolar macrophages: effects of cigarette smoking and sarcoidosis (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-07-13
    Description: Angiotensin I convertase activity has been found in human alveolar macrophages from normal volunteers and patients with pulmonary sarcoidosis. This activity is higher in the alveolar macrophages from smokers than from nonsmokers, and is even more elevated in sarcoid patients. The activity can be detected with both angiotensin I and bradykinin analogs and appears to require protein synthesis, but the enzyme is not secreted by alveolar macrophages in culture.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hinman, L M -- Stevens, C -- Matthay, R A -- Bernard, J -- Gee, L -- New York, N.Y. -- Science. 1979 Jul 13;205(4402):202-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/221980" target="_blank"〉PubMed〈/a〉

    Cerebral specialization, writing posture, and motor control of writing in left-handers (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-21
    Description: It has been suggested that the inverted hand position of left-handers during writing indicates the left hemisphere of their brain is linguistically specialized and that the writing of these left-handers may be controlled via ipsilateral pathways. Electroencephalograph alpha asymmetry measures at central and parietal leads, as well as dichotic tests, differentiated right-handers from left-handers, but not inverters from noninverters. Electroencephalograph differences between hand posture groups did appear, but only at occipital leads during reading and writing tasks. Regardless of hand posture or speech lateralization, the right central region of the brain is significantly involved in the control of left-handed writing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herron, J -- Galin, D -- Johnstone, J -- Ornstein, R E -- New York, N.Y. -- Science. 1979 Sep 21;205(4412):1285-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472745" target="_blank"〉PubMed〈/a〉

    Shifts in perception of size after adaptation to gratings (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: After viewing a suitable grating of vertical stripes for 5 minutes, subjects overestimated the width of a rectangle by 6 percent. The shifts in perception of size occurred whether individual stripes in the grating were narrower than, equal to, or wider than the rectangle. Rectangle width was underestimated only if the grating stripes were extremely wide, with a spatial frequency lower than most of the effective amplitude spectrum of the rectangle. These findings (and complementary ones with horizontal gratings) suggest that the visual system codes size on the basis of spatial frequency components, rather than directly in terms of width.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frome, F S -- Levinson, J Z -- Danielson, J T -- Clavadetscher, J E -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1327-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/515736" target="_blank"〉PubMed〈/a〉

    Cigarette smoking induces functional antiprotease deficiency in the lower respiratory tract of humans (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: Current concepts of the pathogenesis of emphysema suggest that it results from an imbalance of elastase and antielastase activity within the alveolar structures. Although emphysema that is associated with hereditary deficiency of serum alpha 1-antitrypsin conforms to this scheme, the major risk factor in the more common form of emphysema is cigarette smoking. A study was designed to evaluate the premise that cigarette smoking may be associated with an acquired, functional defect in lung alpha 1-antitrypsin. Determination of the antielastase activity of alpha 1-antitrypsin obtained from the lungs of smoking and nonsmoking individuals revealed a nearly twofold reduction in the functional activity of this elastase inhibitor in the lungs of cigarette smokers. These data suggest that cigarette smokers may lose some of the normal antielastase protective screen of the lower respiratory tract, making them more vulnerable to destructive lung disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gadek, J E -- Fells, G A -- Crystal, R G -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1315-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/316188" target="_blank"〉PubMed〈/a〉

    Lithium: a modulator of cyclic AMP-dependent events in lymphocytes? (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-01-26
    Description: Theophylline, salbutamol, isoproterenol, and dibutyryl cyclic AMP inhibited E-rosette formation by human T lymphocytes and immunoglobulin M secretion from human plaque-forming B cells and augmented T-suppressor cell activity in three patients with agammaglobulinemia. Lithium chloride increased mitogen-induced lymphocyte proliferation and inhibited suppressor cell activity. In the presence of lithium, the effects of all the drugs except dibutyryl cyclic AMP could be prevented. The data suggest a role for lithium in the modulation of cyclic AMP-dependent events in lymphocytes. Its potential role as an inhibitor of suppressor cell activity warrants further attention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelfand, E W -- Dosch, H M -- Hastings, B -- Shore, A -- New York, N.Y. -- Science. 1979 Jan 26;203(4378):365-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/216075" target="_blank"〉PubMed〈/a〉

    Automatic classification of electroencephalograms: Kullback-Leibler nearest neighbor rules (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-07-13
    Description: A prototypic problem in screening of electroencephalograms in the automatic classification of stationary electroencephalogram time series is treated here by the Kullback-Leibler nearest neighbor rule approach. In that problem, the category or state of an individual is classified by comparison of his or her electroencephalogram with those taken from other individuals in the alternative categories. The Kullback-Leibler nearest neighbor classification rules yield a statistically reliable estimate of the smallest possible probability of electroencephalogram misclassification with a relatively small number of labeled sample electroencephalograms. The automatic classification of anesthesia levels L1 and L3, respectively the anesthesia levels insufficient and sufficient for deep surgery, is treated by machine computation on the electroencephalogram alone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gersch, W -- Martinelli, F -- Yonemoto, J -- Low, M D -- Mc Ewan, J A -- New York, N.Y. -- Science. 1979 Jul 13;205(4402):193-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451587" target="_blank"〉PubMed〈/a〉

    Electroencephalogram correlates of higher cortical functions (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-02-16
    Description: By means of two-stage, nonlinear multivariate pattern recognition, electroencephalograms (EEG's) were analyzed during performance of verbal and spatial tasks. Complex scalp distributions of theta-, beta-, and, to a lesser extent, alpha-band spectral intensities discriminated between the two members of a pair of tasks, such as writing sentences and Koh's block design. Small EEG asymmetries were probably attributable to limb movements and other uncontrolled noncognitive aspects of tasks. Significant EEG differences beteeen cognitive tasks were eliminated when controls for inter-task differences in efferent activity, stimulus characteristics, and performance-related factors were introduced. Each controlled task was associated with an approximately 10 percent reduction, as compared with visual fixation, in the magnitude of alpha- and beta-band spectral intensity. This effect occurred bilaterally and was approximately the same over occipital, parietal, and central regions, with some minor difference over the frontal region in the beta band. With these controls, no evidence for lateralization of different cognitive functions was found in the EEG.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gevins, A S -- Zeitlin, G M -- Doyle, J C -- Yingling, C D -- Schaffer, R E -- Callaway, E -- Yeager, C L -- New York, N.Y. -- Science. 1979 Feb 16;203(4381):665-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/760212" target="_blank"〉PubMed〈/a〉

    Radioimmunoassay of the insulin receptor: a new probe of receptor structure and function (1979)

    Details
    Publication Date: 1979-02-09
    Description: A sensitive and specific radioimmunoassay for the insulin receptor has been developed employing receptor autoantibodies from the serum of a patient with insulin-resistant diabetes. 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〉

    Defects of bile acid synthesis in Zellweger's syndrome (1979)

    Details
    Publication Date: 1979-03-16
    Description: Abnormal mitochondrial structure and function have been documented in patients with Zellweger's syndrome (cerebrohepatorenal syndrome). In vitro studies have suggested that the formation of C24 bile acids (chenodeoxycholic acid and cholic acid) from C27 cholesterol requires mitochondrial oxidative clevage of the terminal three carbons of the side chain. Therefore, three patients with Zellweger's syndrome were examined for the presence of mitochondrial defects in bile acid synthesis. All three excreted excessive amounts of 3 alpha, 7 alpha-dihydroxy-5 beta-cholestan-26-oicacid, 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-cholestan-26-oic acid, and 3 alpha, 7 alpha, 12 alpha, 24 xi-tetrahydroxy-5 beta-cholestan-26-oic acid (varanic acid), precursors of chenodeoxycholic acid and cholic acid that have undergone only partial side chain oxidation. These findings give added support to the role of mitochondrial oxidative side chain cleavage in the overall scheme of bile acid synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanson, R F -- Szczepanik-VanLeeuwen, P -- Williams, G C -- Grabowski, G -- Sharp, H L -- New York, N.Y. -- Science. 1979 Mar 16;203(4385):1107-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424737" target="_blank"〉PubMed〈/a〉

    Specific nonopiate receptors for beta-endorphin (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-07
    Description: Iodinated beta H-[2-D-alanine]endorphin exhibits specific binding to cultured human lymphocytes. The binding is inhibited by low concentrations of beta-endorphin and its D-alanine derivative, but is not affected by opiate agonists and antagonists, or by enkephalin analogs, beta-lipotropin, adrenocorticotrophic hormone, or alpha-melanocyte-stimulating hormone; this suggests the existence of a specific, non-opiate binding site (receptor) for beta-endorphin. The carboxy-terminal region of beta-endorphin is essential for this binding activity, since alpha-endorphin is not active. beta-Endorphin may be a circulating hormone with peripheral physiological effects that are not primarily mediated through interactions with opiate or enkephalin receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hazum, E -- Chang, K J -- Cuatrecasas, P -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1033-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224457" target="_blank"〉PubMed〈/a〉

    Stimulation of human periaqueductal gray for pain relief increases immunoreactive beta-endorphin in ventricular fluid (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-01-19
    Description: Immunoreactive beta-endorphin was measured in the ventricular fluid of six patients with chronic pain. Stimulation of the periaqueductal gray matter in three patients with pain of peripheral origin resulted in significant increases (50 to 300 percent) in the concentration of ventricular immunoreactive beta-endorphin. In three other patients suffering deafferentation dysesthesia, stimulation of the posterior limb of the internal capsule did not alter the concentration of this peptide. These results provide evidence of the release of human immunoreactive beta-endorphin in vivo and suggest that naloxone-reversible pain relief achieved by stimulation of the periaqueductal gray matter may be in part mediated by the activation of beta-endorphin-rich diencephalic areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hosobuchi, Y -- Rossier, J -- Bloom, F E -- Guillemin, R -- New York, N.Y. -- Science. 1979 Jan 19;203(4377):279-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/83674" target="_blank"〉PubMed〈/a〉

    Risk with energy from conventional and nonconventional sources (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-02-23
    Description: Risk to human health was compared for five conventional and six nonconventional energy systems. The entire cycle for producing energy was considered, not just part. The most important conclusion drawn is that the risk to human health from nonconventional sources can be as high as, or even higher than, that of conventional sources. This result is produced only when the risk per unit energy is considered, rather than the risk per solar panel or windmill. The risk from nonconventional energy sources derives from the large amount of material and labor needed, along with their backup and storage requirements. Risk evaluation is a relatively new discipline, and therefore the results presented here can be considered only a beginning. However, society should keep relative risk in mind when evaluating present and future energy sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Inhaber, H -- New York, N.Y. -- Science. 1979 Feb 23;203(4382):718-23.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/419404" target="_blank"〉PubMed〈/a〉

    Description: Movement time varies as a function of amplitude and requirements for precision, according to Fitts' law, but when subjects perform two-handed movements to targets of widely disparate difficulty they do so simultaneously. The hand moving to an "easy" target moves more slowly to accommodate its "difficult" counterpart, yet both hands reach peak velocity and acceleration synchronously. This result suggests that the brain produces simultaneity of action not by controlling each limb independently, but by organizing functional groupings of muscles that are constrained to act as a single unit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelso, J A -- Southard, D L -- Goodman, D -- New York, N.Y. -- Science. 1979 Mar 9;203(4384):1029-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424729" target="_blank"〉PubMed〈/a〉

    A correlation between platelet monoamine oxidase activity and plasma prolactin concentrations in man (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-10-26
    Description: Increases in plasma prolactin concentrations produced by alpha-methyl-p-tyrosine, a catecholamine synthesis inhibitor, varied inversely with baseline platelet monoamine oxidase activity in 12 patients with chronic schizophrenia. In normal volunteers with low monoamine oxidase activity and in unmedicated patients with chronic schizophrenia, plasma prolactin concentrations varied directly with platelet monoamine oxidase activity. No such relationship was found in normal subjects with high platelet monoamine oxidase activity. These data suggest that platelet monoamine oxidase activity reflects monoaminergic activity in the tubero-infundibular system, which in turn affects plasma prolactin concentrations. This relationship may be important in patients with low platelet monoamine oxidase activity, such as some chronic schizophrenics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleinman, J E -- Potkin, S -- Rogol, A -- Buchsbaum, M S -- Murphy, D L -- Gillin, J C -- Nasrallah, H A -- Wyatt, R J -- New York, N.Y. -- Science. 1979 Oct 26;206(4417):479-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/504993" target="_blank"〉PubMed〈/a〉

    3-Methoxy-4-hydroxyphenethyleneglycol production by human brain in vivo (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-07
    Description: A direct method has been employed to estimate the rate of production by human brain of 3-methoxy-4-hydroxyphenethyleneglycol, the major metabolite of brain norepinephrine, a brain neurotransmitter. Venous specimens were obtained from the internal jugular vein from ten awake human subjects at a puncture site above the common facial vein, the first major source of extracranial inflow. Arterial specimens were simultaneously obtained from the radial artery. Plasma samples were assayed and a highly significant difference was found in the concentration of the metabolite in plasma coming out of the brain (venous blood) as compared to plasma entering the brain (arterial blood). This venous-arterial difference was calculated to be 0.7 +/- 0.1 nanogram per milliliter of blood. Assuming an adult brain weight of 1400 grams and normal cerebral blood flow, it is estimated that the rate of production of 3-methoxy-4-hydroxyphenethyleneglycol by the awake human brain is approximately 597 nanograms per minute or 35.8 micrograms per hour. Urine specimens were also collected from six of these subjects during a period of 1 to 3.5 hours, which bracketed the time the blood samples were obtained. For these six subjects the output of 3-methyoxy-4-hydroxyphenethyleneglycol by whole brain was estimated to be 40.9 micrograms per hour, whereas the rate of its excretion into urine was 64.5 micrograms per hour.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maas, J W -- Hattox, S E -- Greene, N M -- Landis, D H -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1025-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472724" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1979-03-30
    Description: It has recently been shown that perceived motion, in the absence of any appropriate retinal motion, is a sufficient stimulus to generate smooth pursuit eye motions. This raises the question of whether perceived motion is necessary for pursuit. In three experiments we obtained a negative answer to this question: retinal motion always governed pursuit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mack, A -- Fendrich, R -- Pleune, J -- New York, N.Y. -- Science. 1979 Mar 30;203(4387):1361-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424761" target="_blank"〉PubMed〈/a〉

    [3H]GABA binding in brains from Huntington's chorea patients: altered regulation by phospholipids? (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-14
    Description: Binding sites for tritum-labeled gamma-aminobutyric acid (GABA) in cerebellar cortex of Huntington's chorea patients have an increased affinity but unaltered maximum capacity as compared to binding sites in tissue from control patients. A similar binding pattern is produced in control membranes by treatment with Triton X-100, phospholipase C, or glycerophosphoethanolamine. Thus, it is likely that phospholipids or their metabolites regulate the accessibility of the GABA binding site and that this regulation is abnormal in Huntington's chorea.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lloyd, K G -- Davidson, L -- New York, N.Y. -- Science. 1979 Sep 14;205(4411):1147-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224459" target="_blank"〉PubMed〈/a〉

    Description: In each of six family members who were heterozygous at the X-linked locus for glucose-6-phosphate dehydrogenase, only one or the other of the two alleles at that locus was almost exclusively expressed. The data are consistent with evidence that X-chromosome inactivation is a random process that may be followed by selection for one of the two resulting cell types on the basis of an unknown gene, which is located on the X chromosome and which can affect the rate of proliferation of hemopoietic cells in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luzzatto, L -- Usanga, E A -- Bienzle, U -- Esan, G F -- Fusuan, F A -- New York, N.Y. -- Science. 1979 Sep 28;205(4413):1418-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472761" target="_blank"〉PubMed〈/a〉

    Differences in neural organization between individuals with inverted and noninverted handwriting postures (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-17
    Description: Levy's hypothesis that movements of the distal musculature are controlled by ipsilateral motor projections in subjects with inverted writing posture was tested in a reaction-time experiment with lateralized auditory, tactual, and visual stimulation. Subjects were required to depress a response key with the left or right index finger when they detected a stimulus in either the left or right sensory field. Writers with noninverted posture responded quickest to stimuli on the same side as the responding hand in all modalities tested, whereas inverted writers showed this pattern only in auditory and tactual modalities. In the visual modality, they responded quickest to stimuli on the side opposite the responding hand. Because Levy's hypothesis predicts the latter effect in all modalities for inverted writers, it is challenged by our results, which suggest that inverted writers may be characterized by anomalous visual or visuomotor organization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moscovitch, M -- Smith, L C -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):710-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/462180" target="_blank"〉PubMed〈/a〉

    Description: A defect in the binding of insulin to circulating monocytes occurs when obese patients are hospitalized and fed a liberal carbohydrate diet.

    Host defense against Neisseria meningitidis requires a complement-dependent bactericidal activity (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-07-20
    Description: Some individuals, with severe or recurrent infection with Neisseria species, have been identified as lacking a component in the terminal attack sequence of complement (complement components 5 to 9). The relevance of the terminal attack sequence to various phases of host defense was tested with the use of the C-11 strain of meningococci and human serum genetically deficient in complement component 8 (C8-D). The C8-D serum was comparable to normal serum in supporting ingestion and intracellular killing by leukocytes but was not bactericidal in the fluid phase unless reconstituted with C8. Thus, serum complement-dependent bactericidal activity may be especially critical for the host's defense against invasive Neisseria species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicholson, A -- Lepow, I H -- New York, N.Y. -- Science. 1979 Jul 20;205(4403):298-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451601" target="_blank"〉PubMed〈/a〉

    Publication Date: 1979-09-28
    Description: Tetramethylrhodamine labeled N-formyl-Nle-Leu-Phe-Nle-Tyr-Lys is a potent chemoattractant for human neutrophils. Binding of this peptide to living neutrophils was observed by means of video intensification microscopy. At 37 degrees C, diffuse membrane fluorescence was seen initially, followed by rapid aggregation and internalization of the fluorescent peptide. These processes are dependent on specific binding to the formal peptide chemotactic receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Niedel, J E -- Kahane, I -- Cuatrecasas, P -- New York, N.Y. -- Science. 1979 Sep 28;205(4413):1412-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472759" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1979-06-22
    Description: 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〉

    Description: Subdivisions of the human peri-Sylvian language cortex were derived from stimulation mapping during craniotomies under local anesthesia. Naming, reading, short-term verbal memory, single and sequential orofacial movements, and phoneme identification were tested. Sequential orofacial movements and phoneme identification were altered from the same brain sites and thus identified a common system for language production and understanding. This system surrounded a final motor pathway for speech and was surrounded by a separate short-term verbal-memory system. Between the sequential motor-phoneme identification and memory systems were sites where only naming or reading were altered, including sites related exclusively by syntax.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ojemann, G -- Mateer, C -- New York, N.Y. -- Science. 1979 Sep 28;205(4413):1401-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472757" target="_blank"〉PubMed〈/a〉

    Fibrinopeptide B and aggregation of fibrinogen (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-04-13
    Description: Removal of fibrinopeptide B from human fibrinogen by reaction with the procoagulant enzyme from copperhead snake venom below 25 degrees C resulted in tight aggregation of the fibrinogen, which, in turn, progressively blocked a concomitant but sluggish release of fibrinopeptide A by the enzyme. When the clots obtained at less than 25 degrees C were warmed, they dissociated into soluble aggregates and monomers. Release of fibrinopeptide A then resumed, and a secondary coagulation followed. The aggregation induced by release of fibrinopeptide B itself involves a plasmin-susceptible segment located just distal to B in the B beta chain of fibrinogen, a segment previously shown to be of little importance in the aggregation induced by release of fibrinopeptide A.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shainoff, J R -- Dardik, B N -- New York, N.Y. -- Science. 1979 Apr 13;204(4389):200-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/155308" target="_blank"〉PubMed〈/a〉

    Activation of the supplementary motor area during voluntary movement in man suggests it works as a supramotor area (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-11-16
    Description: Measurements of cerebral blood flow in man revealed that complex voluntary movements are associated with a blood flow increase in the supplementary motor area of the brain. This increase is additional to and similar in magnitude to the Rolandic sensorimotor area activation that occurs during all kinds of movement. When subjects counted silently there was no activation of any focal cortical area in the brain; when they counted aloud there was a marked increase in activity in the supplementary motor area. These results are consistent with the hypothesis that the supplementary motor area plays a major role in the initiation and control of at least some kinds of voluntary movement in man and is, therefore, a motor center of a higher order than the primary Rolandic areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Orgogozo, J M -- Larsen, B -- New York, N.Y. -- Science. 1979 Nov 16;206(4420):847-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/493986" target="_blank"〉PubMed〈/a〉

    Publication Date: 1979-06-22
    Description: A 43,000-dalton polypeptide has been isolated from the high-molecular-weight disulfide-rich fraction of the water-insoluble protein of human cataractous lenses. On the basis of immunochemical reactivity and fluorescent antibody binding, this polypeptide is localized in the membrane region of the lens cell. This observation suggests an interaction between the soluble lens proteins and membrane-associated polypeptides in the formation of large protein aggregates which may cause cataract.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spector, A -- Garner, M H -- Garner, W H -- Roy, D -- Farnsworth, P -- Shyne, S -- New York, N.Y. -- Science. 1979 Jun 22;204(4399):1323-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/377484" 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
    Publication Date: 1979-04-27
    Description: 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〉

    Details
    Publication Date: 1979-05-11
    Description: Mathematical analysis and computer and network simulations of the cochlea show that, given appropriate values of specific physical constants, radial shear motion between the tectorial membrane and the reticular lamina may provide the sharpening of frequency analysis observed in cochlear nerve fibers in comparison with the mechanical amplitude distribution on the basilar membrane. According to the analysis, the sharpening occurs through an interaction of the longitudinal mechanical propagation constant of the tectorial membrane with the wavelength on the basilar membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zwislocki, J J -- Kletsky, E J -- New York, N.Y. -- Science. 1979 May 11;204(4393):639-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/432671" target="_blank"〉PubMed〈/a〉

    Phase advance of the circadian sleep-wake cycle as an antidepressant (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-11-09
    Description: Sleep in depressed patients resembles sleep in normal subjects whose circadian rhythms of temperature and rapid-eye-movement sleep are phase-advanced (shifted earlier) relative to their sleep schedules. If this analogy is relevant to the pathophysiology of depressive illness, advancing the time of sleep and awakening should temporarily compensate for the abnormal timing of depressed patients' circadian rhythms. Four of seven manic-depressive patients studied longitudinally spontaneously advanced their times of awakening (activity onset) as they emerged from the depressive phase of their illness. In a phase-shift experiment, a depressed manic-depressive woman was twice brought out of depression for 2 weeks by advancing her sleep period so that she went to sleep and arose 6 hours earlier than usual. The antidepressant effect of the procedure was temporary and similar in duration to circadian desynchronization induced by jet lag in healthy subjects. This result supports the hypothesis that abnormalities of sleep patterns in some types of depression are due to abnormal internal phase relationships of circadian rhythms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wehr, T A -- Wirz-Justice, A -- Goodwin, F K -- Duncan, W -- Gillin, J C -- New York, N.Y. -- Science. 1979 Nov 9;206(4419):710-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/227056" target="_blank"〉PubMed〈/a〉

    Description: An evoked potential component with a poststimulus peak at about 250 milliseconds is related to the storage of information in short-term memory. This storage component was found in an investigation of brain potentials in relation to a number and letter comparison task. In replications of this experiment at three different light intensities spaced 1.0 log unit apart, the component had essentially the same waveform and pattern of scores. The memory storage interpretation was confirmed in a behavioral experiment that probed short-term memory. Recall was predicted by the magnitude of the storage component.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chapman, R M -- McCrary, J W -- Chapman, J A -- New York, N.Y. -- Science. 1978 Dec 15;202(4373):1211-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/725596" target="_blank"〉PubMed〈/a〉

Within 4 weeks at least six other members of the pack were dead. Rabies was confirmed in the wolf that was shot and in two others that had not decomposed. Most of the wolves infected with rabies had sought or remained at familiar areas in the core area of their territory, which implies that they were not contacting neighboring packs. This was confirmed with an aerial survey. Arctic foxes, experiencing a regionwide rabies epizootic, were suspected vectors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chapman, R C -- New York, N.Y. -- Science. 1978 Jul 28;201(4353):365-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/566470" target="_blank"〉PubMed〈/a〉

    Effect of prolonged illumination (phototherapy) on concentrations of luteinizing hormone in human infants (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-03-17
    Description: Concentrations of luteinizing hormone in the serums of human neonates were altered when the neonates were exposed to prolonged, intense illumination (phototherapy) with their eyes covered. Concentrations decreased after 48 to 72 hours of exposure, increased 6 to 9 days after phototherapy, and subsequently returned to levels similar to those of controls. These data suggest that light may affect pituitary-gonadal function in the human neonate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dacou-Voutetakis, C -- Anagnostakis, D -- Matsaniotis, N -- New York, N.Y. -- Science. 1978 Mar 17;199(4334):1229-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/628840" target="_blank"〉PubMed〈/a〉

    Physostigmine: improvement of long-term memory processes in normal humans (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-07-21
    Description: Nineteen normal male subjects received 1.0 milligram of physostigmine or 1.0 milligram of saline by a slow intravenous infusion on two nonconsecutive days. Physostigmine significantly enhanced storage of information into long-term memory. Retrieval of information from long-term memory was also improved. Short-term memory processes were not significantly altered by physostigmine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, K L -- Mohs, R C -- Tinklenberg, J R -- Pfefferbaum, A -- Hollister, L E -- Kopell, B S -- New York, N.Y. -- Science. 1978 Jul 21;201(4352):272-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/351807" target="_blank"〉PubMed〈/a〉

    Other tastes, other worlds (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-07-21
    Description: The idea of four primary tastes has influenced our concept of the gustatory world of all animals. It has also been the basis for constructing theories of gustatory neural integration. Since natural chemical stimuli are complex mixtures to which responses are multineuronal, difficult questions about integration arise. Answers are usually framed in terms of "labeled line" or "across-fiber" hypotheses. Comparative studies of vertebrate and invertebrate taste reveal in all receptors universal basic parameters that bear on the controversy. Comparative studies also place in more accurate perspective diverse chemically related ecologies and behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dethier, V G -- New York, N.Y. -- Science. 1978 Jul 21;201(4352):224-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663651" target="_blank"〉PubMed〈/a〉

    Pitch memory: an advantage for the left-handed (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-02-03
    Description: In an auditory or musical task, subjects made pitch recognition judgments when the tones to be compared were separated by a sequence of interpolated tones. The left-handed subjects performed significantly better than the right-handed and also had a significantly higher variance. Further analysis showed that the superior performance was attributable largely to the left-handed subjects with mixed hand preference.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deutsch, D -- New York, N.Y. -- Science. 1978 Feb 3;199(4328):559-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622558" target="_blank"〉PubMed〈/a〉

    Statistical problems in ESP research (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-07-14
    Description: In search of repeatable ESP experiments, modern investigators are using more complex targets, richer and freer responses, feedback, and more naturalistic conditions. This makes tractable statistical models less applicable. Moreover, controls often are so loose that no valid statistical analysis is possible. Some common problems are multiple end points, subject cheating, and unconscious sensory cueing. Unfortunately, such problems are hard to recognize from published records of the experiments in which they occur; rather, these problems are often uncovered by reports of independent skilled observers who were present during the experiment. This suggests that magicians and psychologists be regularly used as observers. New statistical ideas have been developed for some of the new experiments. For example, many modern ESP studies provide subjects with feedback--partial information about previous guesses--to reward the subjects for correct guesses in hope of inducing ESP learning. Some feedback experiments can be analyzed with the use of skill-scoring, a statistical procedure that depends on the information available and the way the guessing subject uses this information.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diaconis, P -- New York, N.Y. -- Science. 1978 Jul 14;201(4351):131-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663642" target="_blank"〉PubMed〈/a〉

    Deficiencies of glucosamine-6-sulfate or galactosamine-6-sulfate sulfatases are responsible for different mucopolysaccharidoses (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-01-06
    Description: [1-3H]Galactitol-6-sulfate, N- [1-3H]acetylgalactosaminitol-6-sulfate, N-[1-3H]acetylglucosaminitol-6-sulfate, N-acetylglucosamine-6-sulfate, and 6-sulfated tetrasaccharides from chondroitin-6-sulfate have been used for the measurement of 6-sulfatase activity of extracts of normal skin fibroblasts and of fibroblasts cultured from patients with genetic mucopolysaccharidoses. With these substrates, extracts of fibroblasts derived from Morquio patients lack or have greatly reduced activities for galactitol-6-sulfate, N-acetylgalactosaminitol-6-sulfate, and 6-sulfated tetrasaccharides but have normal activity for N-acetylglucosamine-6-sulfate and its alditol; those derived from a patient with a newly discovered mucopolysaccharidosis have greatly reduced activity for N-acetylglucosamine-6-sulfate and its alditol but normal activity for galactitol-6-sulfate, N-acetylgalactosaminitol-6-sulfate, and the 6-sulfated tetrasaccharides. These findings demonstrate the existence of two different hexosamine-6-sulfate sulfatases, specific for the glucose or galactose configuration of their substrates. Their respective deficiencies, causing inability to degrade keratan sulfate and heparan sulfate in one case and keratan sulfate and chondroitin-6-sulfate in the other, are responsible for different clinical phenotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Di Ferrante, N -- Ginsberg, L C -- Donnelly, P V -- Di Ferrante, D T -- Caskey, C T -- New York, N.Y. -- Science. 1978 Jan 6;199(4324):79-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratories of Connective Tissue Research, Department of Biochemistry, Baylor College of Medicine, Houston, Texas 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17569489" target="_blank"〉PubMed〈/a〉
