Bladder cancer is a common and highly heterogeneous malignancy with a relatively poor outcome. Patient-derived tumor organoid cultures have emerged as a preclinical model with improved biomimicity. However, the impact of the different methods being used in the composition and dynamics of the models remains unknown. This study aims to systematically review the literature regarding patient-derived o

Introduction: Deliberate self-harm (DSH) is common in clinical populations. Childhood maltreatment (CM) and attitudes both towards oneself and towards DSH may be of importance for the development of DSH. This study aimed to test whether patients with DSH report more CM, more negative attitudes towards oneself and more positive attitudes towards DSH than a clinical and a healthy comparison group, a

How does violent conflict affect the spread of Covid-19? In this paper we analyze how violent conflict influences the adoption of preventative measures and infection rate in a very poor, conflict-affected country, Burkina Faso. We use a unique panel of 1,919 households surveyed during the first six months of the Covid-19 pandemic in 2020 and merge these data with indicators of violence at the muniHow does violent conflict affect the spread of Covid-19?

Objectives Dietary supplements may ameliorate SARS-CoV-2 infection, although scientific evidence to support such a role is lacking. We investigated whether users of the COVID-19 Symptom Study app who regularly took dietary supplements were less likely to test positive for SARS-CoV-2 infection. Design App-based community survey. Setting 445 850 subscribers of an app that was launched to enable self

OBJECTIVE: Poor metabolic health and unhealthy lifestyle factors have been associated with risk and severity of COVID-19, but data for diet are lacking. We aimed to investigate the association of diet quality with risk and severity of COVID-19 and its interaction with socioeconomic deprivation. DESIGN: We used data from 592 571 participants of the smartphone-based COVID-19 Symptom Study. Diet info

The main focus of this paper is the empirical modelling of the wear of carbon brushes. Rather than determining the dominant wear mechanisms, an approach towards the prediction of wear under a range of different conditions was used. The models were obtained by multiple regression analysis using lifetime (LT) data contributed by the biggest European manufacturer of vacuum cleaner motors. This includ

BACKGROUND: Although gambling disorder is traditionally considered an adult phenomenon, the behavior usually begins in childhood or adolescence.OBJECTIVE: The aim of this study was to explore the frequency of problem gambling among Swedish adolescents and the suspected associated factors.METHODS: This study was based on data collected through a public health survey distributed in 2016 to pupils in

This collection seeks to illustrate the state of the art in territoriological research, both empirical and theoretical. The volume gathers together a series of original, previously unpublished essays exploring the newly emerging territorial formations in culture, politics and society.While the globalisation debate of the 1990s largely pivoted around a ‘general deterritorialisation’ hypothesis, sin

Controllable doping in semiconductor nanowires is essential for development of optoelectronic devices. Despite great progress, a fundamental challenge remains in controlling the uniformity of doping, particularly in the presence of relatively high levels of geometrical inhomogeneity in bottom-up growth. A relatively high doping level of 1E18 cm-3 corresponds to just ~1000 activated dopants in a 2µ

Incorporating rigid cyclic acetal and ketal units into polymer structures is an important strategy towards high-performance materials from renewable resources. In the present work, citric acid, a widely used platform chemical derived from biomass, has been efficiently converted into diand tricyclic diketones. Ketalization with glycerol or trimethylolpropane afforded rigid spirodiols, which were ob
