Lutein is present in the human retina and lens, where it plays a protective role. As lutein is associated with the lipid matrix of biomembranes, the role depends on its membrane location. Experimental studies predicted two orientations of lutein in a phosphatidylcholine (PC) bilayer: vertical and horizontal. Using a molecular dynamics simulation, we observed, in two different PC bilayers, both ...

Using a longitudinal design, a sample of ninety young people was followed for ten years, from their initial adolescence until their first years of adulthood. At four observation points...

The incidences of many cancers can be very different in men and women. Besides differences in exposures to putative causative agents, it is plausible that both genetic and epigenetic effects play roles in these differences. In addition, gender-specific lifestyle and behavioural factors may modulate the effects of exposure to genotoxins. This commentary focuses on several aspects of gender-relat...

In this paper we present an argument that sex serves as a foundational metaphor for much of computer science, Human-Computer Interaction and human thought more generally. While human sexual behavior is highly variable throughout history and geography, we further argue that a specific orientation toward sexual behavior underlies most of the current work in human-computer interaction. Further, we...
