    Notes: Abstract: We report here on the binding properties of [3H]hemicholinium-3, a selective inhibitor of the high-affinity choline uptake process, to human brain membranes. Under the assay conditions described, the binding of [3H]hemicholinium-3 exhibited a dependency of physiological conditions on pH, temperature, and NaCl concentrations. Striatal binding proved to be specific, to a single site, saturable, and reversible, with an apparent KD of 10 nM and a Bmax of 82 fmol/mg of protein. [3H]Hemicholinium-3 specific binding exhibited a pharmacological profile and an ionic dependency suggestive of physiologically relevant interactions and comparable with those reported for the high-affinity choline uptake. Moreover, specific [3H]hemicholinium-3 binding exhibited an uneven regional distribution: striatum ≫ nucleus basalis 〉 spinal cord ≫ midbrain = cerebellum ≧ hippocampus 〉 neocortex = anterior thalamus 〉 posterior thalamus ⋙ white matter. This distribution closely corresponds to the reported activity of both enzymatic cholinergic presynaptic markers and high-affinity choline uptake in mammalian brain. There are no significant differences between these results and those previously found in the rat brain using this radioligand. Our results demonstrate, for the first time, the presence of [3H]hemicholinium-3 binding sites in human brain and strongly support the proposal that this radioligand binds to the carrier site mediating the high-affinity choline uptake process on cholinergic neurons. Thus, [3H]hemicholinium-3 binding may be used in postmortem human brain as a selective and quantifiable marker of the presynaptic cholinergic terminals.

    Notes: Abstract: To examine directly in the brain the status of α2-adrenoceptors in major depression, the specific binding of the agonist [3H]UK 14304 was measured by quantitative receptor autoradiography in the hippocampus and frontal cortex of suicide victims (n = 17) with a retrospective diagnosis of depression (n = 7) or other psychiatric disorders (n = 10) as well as of matched control subjects (n = 9). In suicide victims, a significant increase in the number of α2-adrenoceptors was found in the CA1 field (40%) and dentate gyrus (20%) of the hippocampus and in the external layers I (33%) and II (31%) of the frontal cortex, compared with that in matched controls. In depressed suicide victims, the increase in α2-adrenoceptors in the CA1 field (57%) was significantly greater (24%, p 〈 0.05) than that observed in the group of suicide victims with other diagnoses (26%). In the same depressed suicide victims, the increase in cortical α2-adrenoceptors was restricted to layer I (34%) and it was equivalent to that found in layer I (33%) of suicide victims with other diagnoses. The results indicate that suicide is associated with increases in the high-affinity state of brain α2-adrenoceptors and that there is a pronounced localized increase of this inhibitory receptor in the hippocampus of depressed suicide victims.

    Notes: Starting from our general critical-state theory, which includes the effects of both flux-line cutting and flux pinning, we develop a numerical method for finding the magnetic response of type-II superconductors subjected to parallel magnetic fields that change in both magnitude and orientation. We describe model calculations of the time-evolving magnetic profiles when the direction of an applied magnetic field of fixed magnitude oscillates with large amplitude, and we compare our results with related experiments by Cave and LeBlanc. We also report model calculations for the ac behavior when the sample is subjected to a dc bias field and a large-amplitude ac field at various angles (0°, 45°, and 90°) relative to this field.
