    Description / Table of Contents: Abstract The IUGS Subcommission on the Systematics of Igneous Rocks herein presents its recommendations on the nomenclature and classification of pyroclastic and mixed pyroclastic-epiclastic deposits using descriptive, mainly granulometric, criteria. The recommendations are the result of an international inquiry by means of questionnaires during the last four years.

    Unidirectional habituation of vestibulo-ocular responses by repeated rotational or optokinetic stimulations in the cat (1981)
    Springer
    Experimental brain research 42 (1981), S. 34-42

    Notes: Summary 1.Unilateral habituation of the vestibuloocular reflex was produced in adult cats stimulated by repeated unidirectional velocity steps (vestibular training) or by a continuously moving visual surround (optokinetic training). — 2. Unidirectional vestibular training produced a strong asymmetry of vestibuloocular responses (VOR). Responses to velocity steps applied to the “trained” labyrinth were decreased both in gain and in time-constant. This effect generalized to responses to sinusoidal oscillations (0.03 Hz to 0.1 Hz), i.e. to a stimulus not used during training. — No spontaneous nystagmus was ever observed in spite of the dynamic VOR asymmetry. — 3. Unilateral vestibular habituation produced by vestibular training appeared to be a long-lasting phenomenon. It was still present 10 days after the end of training. — 4. Optokinetic responses were not affected by vestibular training. — 5. Unidirectional optokinetic training produced an increase in the slow phase velocity of optokinetic nystagmus (OKN) by about 25% in both directions. This effect did not persist for more than a few minutes. A marked spontaneous nystagmus was recorded in the dark after each session of optokinetic training, with a slow phase in the direction opposite to the previous OKN. — 6. VOR in response to velocity steps and to sinusoidal oscillations were decreased unilaterally after optokinetic training. This effect was of short duration, however, and disappeared within the interval between training sessions. This lack of retention contrasted with the prolonged effect of vestibular training.

    Endogenous inhibitors of Na+-independent [3H]GABA binding to crude synaptic membranes (1981)
    Springer
    Neurochemical research 6 (1981), S. 551-565 
    Details

    Topics: Medicine
    Notes: Abstract The characteristics of the Na+-independent high-affinity binding of [3H]GABA to various types of crude synaptic membranes (CSM) prepared from rat brain cortex were studied. In freshly prepared CSM the content of GABA was so high that the high-affinity [3H]GABA binding could not be determined. In contrast when the frozen-thawed CSM were incubated at 37° for 30 min with or without Triton X-100 or phospholipase C and then washed repeatedly, there was a virtual disappearance of GABA from the supernatant extracts and the binding constants of [3H]GABA to CSM could be determined. Two apparent populations of [3H]GABA binding sites, one with a low- and the other with a high-affinity constant, were detected. The ratio of the number of high- to low-affinity binding sites varies with the method used to prepare the membranes. The lowest value of this ratio was observed with membranes incubated at 37° for 30 min. However, when frozen-thawed CSM were treated with 0.05% Triton X-100 repeatedly, the ratio of the number of high- to low-affinity binding sites increased progressively. This increase in ratio is due to a selective increase in the number of the high-affinity sites without significant changes in the number of the low-affinity sites. The extent of the increase in the number of sites that bind [3H]GABA with high affinity after repeated Triton X-100 treatments was paralleled by a decrease of an endogenous protein which inhibits GABA binding. The reapplication of this endogenous material to membranes repeatedly treated with Triton X-100 reduces the number of high-affinity binding sites for [3H]GABA to values similar to those measured in membranes that were not treated with Triton X-100. The inhibitory preparation extracted from CSM incubated with Triton X-100 was shown to be free of GABA or phospholipids. The gel filtration chromatography reveals the presence of two molecular forms of the inhibitor; of these, the high-molecular-weight material fails to bind GABA, whereas the low-molecular-weight material appears to bind GABA. The high-molecular-weight endogenous inhibitor has been termed GABA modulin.
