Measurement of apolipoprotein B-48 in the Svedberg flotation rate (Sf) > 400, Sf 60 – 400 and Sf 20 – 60 lipoprotein fractions reveals novel findings with respect to the effects of dietary fatty acids on triacylglycerol-rich lipoproteins in postmenopausal women

The present study was designed to examine whether the type of fat ingested in an initial test meal influences the response and density distribution of dietary-derived lipoproteins in the Svedberg flotation rate (Sf)>400, Sf 60 - 400 and Sf 20 - 60 lipoprotein fractions. A single-blind randomized within-subject crossover design was used to study the effects of palm oil, safflower oil, a mixture of fish and safflower oil, and olive oil on postprandial apolipoprotein (apo) B-48, retinyl ester and triacylglycerol responses in each lipoprotein fraction following an initial test meal containing one of the oils and a second standardized test meal. For all dietary oils, late postprandial (300min) concentrations of triacylglycerol and apo B-48 were significantly higher in the Sf 60 - 400 fraction than in the Sf>400 fraction (P<0.02). Significantly greater apo B-48 incremental areas under the curve (IAUCs) were also observed in the Sf 60 - 400 fraction than in the Sf>400 fraction following palm oil, safflower oil and olive oil (P<0.04), with a similar non-significant trend for fish/safflower oil. Olive oil resulted in a significantly greater apo B-48 IAUC in the Sf>400 fraction (P<0.02) than did any of the other dietary oils, as well as a tendency for a higher IAUC in the Sf 60 - 400 fraction compared with the palm, safflower and fish/safflower oils. In conclusion, we have found that the majority of intestinally derived lipoproteins present in the circulation following meals enriched with saturated, polyunsaturated or monounsaturated fatty acids are of the density and size of small chylomicrons and chylomicron remnants. Olive oil resulted in a greater apo B-48 response compared with the other dietary oils following sequential test meals, suggesting the formation of a greater number of small (Sf 60 - 400) and large (Sf>400) apo B-48-containing lipoproteins in response to this dietary oil.

Women in art: the last taboo

The intention of this paper is to explore traditions and current trends in art with particular reference to the depiction of female experiences such as pregnancy, abortion, birth and motherhood. The inclusion and exclusion of such images in art history over time and across societies reflects prevailing attitudes, whilst affirming various stereotypical and gendered constructions developed and sustained within those societies. These constructions in turn relate to criteria defined by class, access to education and notions of femininity. Work by artists which feature aspects of these experiences (particularly childbirth), is considered taboo by many in a Western society which continues to render the essentially female experience as private, invisible and stigmitised and confuses the natural with the sexual. The work of undergraduate art students, inspired by the artwork of women artists who make explicit or are influenced by essentially female experiences, is discussed and attempts made to connect their work to the issues outlined.

Healthcare providers in the English National Health Service: public, private or hybrids?

In recent years it has been noted that boundaries between public and private providers of many types of welfare have become blurred. This paper uses three dimensions of publicness to analyse this blurring of boundaries in relation to providers of healthcare in England. The authors find that, although most care is still funded and provided by the state, there are significant additional factors in respect of ownership and social control which indicate that many English healthcare providers are better understood as hybrids. Furthermore, the authors raise concerns about the possible deleterious effects of diminishing aspects of publicness on English healthcare. The most important of these is a decrease in accountability

Cross-cultural generality and specificity in self-regulation: avoidance personal goals and multiple aspects of well-being in the United States and Japan

The authors examined avoidance personal goals as concurrent (Study 1) and longitudinal (Study 2) predictors of multiple aspects of well-being in the United States and Japan. In both studies, participants adopted more avoidance personal goals in Japan relative to the United States. Both studies also demonstrated that avoidance personal goals were significant negative predictors of the most relevant aspects of well-being in each culture. Specifically, avoidance personal goals were negative predictors of intrapersonal and eudaimonic well-being in the United States and were negative predictors of interpersonal and eudaimonic well-being in Japan. The findings clarify and extend puzzling findings from prior empirical work in this area, and raise provocative possibilities about the nature of avoidance goal pursuit.
