Attachment to the mother at 1 year of age was studied in 46 "high-risk" offspring of index mothers with a history of nonorganic psychosis and in 80 demographically similar control offspring. Attachment was measured in the home in a standardized manner by a modified version of Ainsworth's Strange Situation procedure. Three different patterns, representing(More)
In safety assessments of nuclear facilities, a wide range of radioactive isotopes and their potential hazard to a large assortment of organisms and ecosystem types over long time scales need to be considered. Models used for these purposes have typically employed approaches based on generic reference organisms, stylised environments and transfer functions(More)
Exploratory behavior and deviations on three dimensions--fear of strangers, attachment to mother, and exploration--were studied in 46 infants of mothers with a history of psychosis and 80 control infants. While high-risk infants did not differ from controls on exploration alone, they showed multiple deviations on the three dimensions more frequently than(More)
Mother-infant interaction during feeding and in an unstructured play situation was studied in the home at 3.5 and 6 months of age in index mother-infant pairs in which the mother had a history of nonorganic psychosis (n = 48 and 52 at 3.5 and 6 months, respectively) and in demographically similar control pairs (n = 80 and 79). Interaction was significantly(More)
Mother-infant interaction during feeding and in an unstructured play situation was studied in the home at 1 year of age in 46 index mother-infant pairs in which the mother had a history of nonorganic psychosis and in 80 demographically similar control pairs. As was true at the five previous observation ages, some aspects of the interaction were(More)
Mother-infant interaction during feeding and in an unstructured play situation was studied in the home at 3 weeks and 6 weeks of age in index mother-infant pairs in which the mother had a history of nonorganic psychosis (n = 42 and 51 at 3 and 6 weeks, respectively) and in demographically similar control pairs (n = 60 and 78). At both ages, interaction was(More)
An automatic enzyme kinetic luminometric method for determination of small quantities of urea in biological fluids and in microdialysates is presented. The method is based on the ATP-hydrolyzing urease reaction [urea amidohydrolase (ATP-hydrolyzing); EC 3.5.1.45], monitored by a luciferin-luciferase ATP reaction. The assay range is 100 pmol to 50 nmol with(More)
This article describes the development of a prospective, longitudinal study of 88 "high-risk" offspring of pregnant index women with a history of nonorganic psychoses and 104 offspring of demographically-similar pregnant control women. The maternal psychoses represented the diagnostic categories, Schizophrenia, Cycloid Psychosis, Affective Illness,(More)
Mother-infant interaction during a feeding was studied at about 3 days of age in 51 index mother-infant pairs in which the mother had a history of nonorganic psychosis and in 73 demographically similar control pairs. Interaction was significantly more negative and deviant in index than control cases, index mothers establishing a significantly more negative(More)
A quantitative assessment of the levels of cytochromes P-450 b and P-450 c in the brains and pituitary glands of untreated and beta-naphthoflavone (BNF)-pretreated rats was made with polyclonal antibodies raised against hepatic P-450 b and c and the sensitive fluorometric assay of P-450 catalytic activity, namely, the O-deethylation of ethoxycoumarin (ETC).(More)
