Mood and cognition in pregnant workers.

Thirty-eight working women, in their late second trimester or early third trimester of pregnancy, volunteered to fill out the Cognitive Failures Questionnaire and the UWIST Mood Adjective Checklist. In addition they provided information on the number of children they already had, the nature of their employment and their education level. The latter information was used to select a match for each pregnant worker from a larger sample of non-pregnant female workers.

Human microvascular endothelial cell-extracellular matrix interaction in cellular growth state determination.

We introduce two methods, both of which are based on cellular-extracellular matrix interaction, which will facilitate the study of human microvascular endothelial cells. One method describes the means to obtain a G1 population baseline in human microvascular endothelial cells. Because of the contribution of the extracellular matrix in endothelial cell growth, synchronization in G1 was possible only after the incorporation of angiostatic levels of heparin and hydrocortisone into the extracellular matrix.

Characteristics of visual interference with visuospatial working memory.

Recent discussions of visuospatial working memory have suggested that this subsystem may incorporate a visual buffer which holds visuospatial information relatively passively. Empirical investigations of visual interference with information held within a visuospatial subsystem have yielded somewhat equivocal results. Nonetheless, evidence from Logie (1986) has indicated that visuospatial processing can be disrupted by passive exposure to irrelevant visual material in a manner analogous to the disruption of serial verbal recall by exposure to irrelevant speech.

In utero exposure to diagnostic ultrasound: a 6-year follow-up.

A 6-year follow-up study of height and weight was conducted between 1975 and 1983 in a total of 149 sibling pairs of the same sex, one of whom had been exposed to diagnostic ultrasound in utero. The data were analyzed for the entire sample group, as well as for subgroups defined by sex, gestational age at delivery, birth order, and gestational age at time of first exposure to ultrasound. No statistically significant differences of head circumference at birth or of height and weight between birth and 6 years of age were found between ultrasound-exposed and unexposed siblings.

Clinical dosimetry for radiotherapy to the breast based on imaging with the prototype Royal Marsden Hospital CT simulator.

The result of conservative management of breast cancer is strongly dependent on the homogeneity of the dose delivered a schedule of post-surgical radiotherapy. In addition to improvements in local control, late normal-tissue effects should be minimised by achieving a good dose homogeneity. The Royal Marsden Hospital prototype CT simulator has been used to image patients in the treatment position.

Benign muscular dystrophy with contractures: a new syndrome?

Three patients are described with muscular dystrophy and contractures. Although this disorder bears similarities to Emery-Dreifuss disease and variants previously described, absence of cardiomyopathy is a distinguishing feature. Electrodiagnostic testing and muscle biopsy are consistent with a myopathy.
