Neuroblastoma is one of the most common paediatric malignancies. Detection of somatic genetic alterations in this tumour is instrumental for its risk stratification and treatment. On the other hand, an absence of detected chromosomal imbalances in neuroblastoma biopsies is difficult to interpret because it is unclear whether this situation truly reflects the tumour genome or if it is due to subopt

Hypothermic treatment after birth asphyxia was introduced as a recommended practice in Sweden in 2007. CPUP is a national quality register and surveillance program that encompasses the total population of children with cerebral palsy (CP) in Sweden. In an analysis of CPUP data children with CP and asphyxia treated with cooling were compared to children with CP and asphyxia who were not cooled. A l

Background: Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL·kg−1·h−1, but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss d

When children use the Internet, they commonly choose to watch their favorite YouTubers. In this article, we aim to deepen the understanding of how children make sense of YouTubers as a phenomenon, and the role of microcelebrities in children’s everyday life. The study is based on group interviews with 9- and 12-year-old Swedish children, and pays specific attention to how they make sense of the vi

Objectives This study aims to estimate the relationship between non-alcoholic fatty liver disease (NAFLD) and measures of atherosclerotic cardiovascular disease (ASCVD), and to determine to what extent such relationships are modified by metabolic risk factors. Methods The study was conducted in the population-based Swedish CArdioPulmonary bioImage Study (SCAPIS) pilot cohort (n = 1015, age 50–64 y

Metastatic breast cancer is responsible for most breast cancer-related deaths. Disseminated cancer cells have developed an intrinsic ability to resist anchorage-dependent apoptosis (anoikis). Anoikis is caused by the absence of cellular adhesion, a process that underpins lumen formation and maintenance during mammary gland development and homeostasis. In healthy cells, anoikis is mostly governed b

Just like current software systems, models are characterised by increasing complexity and rate of change. Yet, these models only become useful if they can be continuously evaluated and validated. To achieve sufficiently low response times for large models, incremental analysis is required. Reference Attribute Grammars (RAGs) offer mechanisms to perform an incremental analysis efficiently using dyn

We present a label-free method capable of rapidly sorting particles based on their densities. Our device relies on deterministic lateral displacement (DLD) and achieves density fractionation by the use of T-shaped posts. By combining it with a lateral density gradient we achieve a density separation that is independent of size within a range given by the device geometry. Herein we present a proof-

The inherent properties of cells and micro-organisms is an under-explored source of specificity for particle sorting. In contrast to standard immunolabeling it allows us to perform fractionation without any chemical preparation of the sample. This improves the accessibility and affordability of the technology. Our contribution in the field is to extend the scope of deterministic lateral displaceme

We have developed an assay, based on nanofluidic channels and fluorescence microscopy, for optical mapping of DNA based on competitive binding between two molecules - one fluorescent and one sequence selective. From the experimental data we can extract binding constants for the two competing DNA binders, which may be subsequently used to calculate a theoretical reference map of any DNA with known

We present a deterministic-lateral-displacement (DLD) device that extends the capabilities of this traditionally sizebased particle separation technique to also be sensitive to density. By the use of T-shaped posts instead of the normally cylindrical posts the particle trajectory through the device will be a function of its vertical position which in turn is determined by the buoyancy of the parti

We have studied a selection of factors influencing the damage of DNA in nanochannels during fluorescence imaging. For cutting and nicking of DNA we show that the DNA is shortened during imaging. To avoid photodamage over the course of several hours of a typical experiment, we demonstrate the importance of an oxygen free gas to propel the buffer solution through the device. Finally, by varying the
