Dopamine-beta-hydroxylase and its apparent endogenous inhibitory activity in the plasma of some psychiatric patients

Abstract: The “apparent” and “absolute” levels of dopamine-β-hydroxylase (DBH) in 62 psychiatric patients and 20 healthy control subjects have been investigated. No significant differences could be detected between control subjects and patients diagnosed as schizophrenic, unipolar depressive and bipolar depressive, when DBH was assayed in the presence of the anti-inhibitors Cu++ and N- ethylmaleimide (i.e., “absolute” DBH activity). In the absence of these anti- inhibitors, however, the levels of plasma DBH (i.e., “apparent” DBH activity) were considerably reduced in all cases, with the schizophrenic group also being significantly reduced (p<0.02) in comparison with the control group.

A typology of internal migration

Abstract: The objective of this article is to show that the traditional literature on internal migration or population mobility discusses a number of dimensions of (or types of) flows of people. These aspects of repeat migration cyclic or return migration population turnovers long-term stability and population growth are used to define a multivariate Mover-Stayer Typology. The typology specifies 32 patterns of internal migration or population mobility. The authors suggest that "the major implication resulting from the development of the Mover-Stayer Typology is that mobility or migration cannot be measured by a single measure but must take into account its varied aspects. The central theme of the article is that mobility or migration is not a variable but is a complex of variables...and that analyses of internal migration that fail to consider the various aspects of mobility noted are conceptually as well as methodologically unsound." An illustration based on Canadian data is included. (summary in FRE) (EXCERPT)
