BACKGROUND: Many studies have indicated that colon and rectal cancers differ in etiology and histology. OBJECTIVE: The aim of this study was to investigate whether the associations of colon and rectal cancers with any other (discordant) cancer were site specific. DESIGN: A novel approach was implemented in which cancer risks were analyzed in families with increasing numbers of family members diagn

Computers and digital instruments change the way we think about ourselves and other people, demonstrated by an example with a girl who imagined that she had a computer in her brain where she could click on “Music” in the menu to hear music. This chapter argues that good music technology should allow play and unpredictable events and support a balance between challenge and ability. Digital instrume

This chapter explores how nursing home managers grapple with local manifestations of the wicked problems that plague elderly care. It shows the tension between managers' lofty ideals of high-quality, individualized care and their continuous struggle to handle very basic troubles that ultimately appear to be grounded in a lack of resources, such as high personnel turnover and staff complaints about

Numerous species of nematodes have evolved to inhabit the gastrointestinal tract of animals and humans, with over a billion of the world's population infected with at least one species. These large multicellular pathogens present a considerable and complex challenge to the host immune system given that individuals are continually exposed to infective stages, as well as the high prevalence in endem

The future of nations and nationalism appears to many to be more uncertain than ever in view of the growing interdependence of the planet. The question of whether globalization heralds the end of nationalism cannot be answered properly without distinguishing between nation and state. In the case of the state, the question is whether states can preserve their sovereignty intact in an age when polit

In this work, we utilize classical polymer density functional theory (DFT) to study gelation in systems containing colloidal particles onto which polymers are grafted. The solution conditions are such that the corresponding bulk system displays a lower critical solution temperature (LCST). We specifically compare our predictions with experimental results by Shay et al. (J. Rheol. 2001, 45, 913-927

In particular, I look at how traces of Zhuangzi’s butterfly dream appear in the oneiric fictions of Argentinian writer Jorge Luis Borges, and how, in turn, Borges’ dream-worlds have inspired Chinese author Can Xue to create a new kind of literary dreamscape.

Dissipative particle dynamics (DPD) have been widely used for the simulations of dynamics of both simple and complex fluids at nano/micro scales. In these simulations, periodic boundaries are usually employed in the main flow direction and the characterization of the flow and heat transfer is based on fully developed conditions. In the real nano/micro-fluidic devices, however, there are entrances

Colour–magnitude diagrams (CMDs) are powerful tools that might be used to infer stellar properties in globular clusters (GCs), for example, the binary fraction and their mass ratio (q) distribution. In the past few years, observations have revealed that q distributions of GC main-sequence binaries are generally flat, and a distribution characterized by a strong increase towards q ≈ 1 is not typica

Vi redogör för ett patientfall med covid-19-associerad myokardit.Patienten hade förhöjda hjärtskademarkörer, men inte avsevärt stegrade inflammationsmarkörer såsom D-dimer och interleukin-6. Tidigare fallrapporter indikerar att en myokarditbild kan uppträda vid covid-19, både genom förekomst av sars-cov-2 i myokardiet och immunologisk aktivering. I detta fall var orsaken sannolikt infektion i myok

BACKGROUND: Phaeochromocytoma is sometimes not diagnosed before surgery and may present as an adrenal incidentaloma. The aim of this study was to investigate differences in clinical presentation and perioperative outcome in patients with subclinical and symptomatic phaeochromocytoma, and in patients operated with and without preoperative α-blockade. METHODS: This was a retrospective observational

Bergh considers the relationship between migration and interpersonal trust in the European Union. Interpersonal trust, Bergh avers, is an important foundation for a well-functioning society. The question is how interpersonal trust is affected by increased migration in countries with differing levels of trust. Bergh shows that migrants from low-trust countries who move to high-trust ones show highe
