(1982)Conditions were found for stabilizing rat brain cortex kainic acid (KA) receptors. Such receptors had the same Hill number (about 0.6) for KA and for glutamate. The receptors were then used as detectors for endogenous ...
-
(1982)The distribution of 5'-nucleotidase activity in pre-implantation mouse embryos is studied by means of a cytochemical method adapted from Uusitalo & Karnovsky (1977). The enzyme activity is detected from the 4-cell stage ...
-
(1982)Two-cell mouse embryos were cultured in vitro for different periods in a medium in which NaCl was partially replaced by LiCl at concentrations ranging from 1 to 30 mM. The relative cell number diminished according to ...
-
(1982)A large sib-sib phenotypic discordance for the Rh system has been found in a longitudinal follow-up study on growth and development. Sibs born no more than 3 years later than their respective indexes show a significant ...
-
(1982)Different effects of oestrogen are mediated separately, by independent mechanisms of action. Accordingly, it has been shown that it is possible to dissociate these effects under various conditions which stimulate or inhibit ...
-
(1982)In order to elucidate the mechanism of action of organochlorine insecticides on the ion transport in biological membranes, we have studied the effect of DDT and its analog DDE on the structural parameters of phosphatidyl ...
-
(1982)This report presents data showing that extraverts (Eysenck Personality Inventory) develop larger positive vertex slow potentials than introverts under extinction conditions ('no go' instruction in a fixed foreperiod reaction ...
-
(1982)Spermatozoen‐Immobilisierung durch Zahn‐Fokus‐Mikroorganismen Seit langem wird die Frage diskutiert, inwieweit fokale Infektionen in der Lage sind, in verschiedenen Geweben bestimmte Veränderungen auszulösen. Zweck der ...
-
(1982)In 27 encéphale isolé cats, electrical stimulation of the pulvinar-lateralis posterior nucleus complex (P-LP) evoked oblique conjugate saccadic eye movements, with latencies of 60 to 90 ms and stimulus thresholds of 200 ...
-
(1980)Phosphomevalonate kinase from pig liver is inactivated by 5,5'-dithiobis(2-nitrobenzoate) and pyridoxal 5'-phosphate. The substrate phosphomevalonate protects the enzyme against inactivation by these reagents. Inactivation ...
-
(1982)Extracellular recordings were made from cells in the ventral lateral geniculate (GLv) of the Japanese quail (Coturnix coturnix japonica), and their responses studied with chomatic stimuli. A total of 156 units were studied, ...
-
(Martinus Nijhoff/Dr. W. Junk Publishers, 1981)An adenylate cyclase activity was identified and characterized in preparations from Xenopus laevis ovarian tissue and follicles. The enzyme is more active in the presence of Mn2+ than of Mg2+, and it is highly activated ...
-
(1981)Production of leukocyte migration inhibition factor was measured in vitro with purified protein derivative and phytohemagglutinin in 14 marasmic infants 6 to 18 mth of age. 27 well-nourished infants served as controls. All ...

(1981)A technique of muscular relaxation based on the combination of auditory stimulation and electromyographic biofeedback was applied to thirty-three patients with bruxism and myofascial pain-dysfunction syndrome (MPD syndrome), ...
