Background: Children aged 0–18 years who need long-term respiratory support rely on medical technology and comprehensive medical care. For this care to be provided at home, access to medical and social support and care is essential. In Sweden, the most notable form is personal care assistance (PCA), which is granted based on legislation and individual authority decisions. We aim to explore the imp

Physics classrooms are still clearly marked by practices belonging to a certaineducational past, while teachers are increasingly being asked to teach in lignment with current equality, diversity and inclusion agendas. At the core of this temporal disconnect are teachers’ practices, which are strongly marked by normative regimes in terms of gender, race, ethnicity, class and other social factors. M

Background: Depressed suicide attempters are, according to some earlier studies, treated more often with antipsychotics than depressive non-suicide attempters. Cluster B personality disorders, especially borderline personality disorder, are associated with a high suicide risk, and antipsychotics are commonly used for the reduction of symptoms. However, no previous study has taken comorbid personal

Swedish National Board of Housing, Building and Planning reported in "Energi i bebyggelsen"that 80 % of the detached houses in Sweden were under-ventilated, and had a flow of 0.23 l/(s·m2) on average instead of, by the code, required 0,35 l/(s·m2). Well known concerns here are lacking indoor environmental quality and a risk of moisture problems in certain rooms and in the envelope. The naturally v

Adaptive plasticity processes are required involving neurons as well as non-neuronal cells to recover lost brain functions after an ischemic stroke. Recent studies show that gamma-Aminobutyric acid (GABA) has profound effects on glial and immune cell functions in addition to its inhibitory actions on neuronal circuits in the post-ischemic brain. Here, we provide an overview of how GABAergic neurot

Bakgrund Framväxten av hälsoapplikationer som gör det möjligt för patienter att kontakta och kommunicera med vårdpersonal digitalt kan förändra hur patienter ser på sin vård och hur de kontaktar vårdpersonalen (WHO, 2011). Digitala system kan också, utifrån sin design, ge förutsättningar för relationscentrerad vård genom att patienterna ges möjlighet att, i samverkan med vårdpersonalen, vara aktiv

We present a microfluidic system to control the position of particles (polystyrene beads or astrocyte cells) in hydrogel droplets using bulk acoustic standing waves. Droplets comprising hydrogel precursor solution, photoinitiator and (bio-)particles were generated and acoustic forces focused the beads to the droplet center line. Droplets were cross-linked by exposure to UV-light. With the acoustic

This contribution reports a novel method for cell-supernatant separation inside nanoliter droplets with separation efficiencies for single cells of 100% at flow speeds of 2 mm/s. Cells are focused in nanoliter droplets using bulk acoustic waves before the droplet is split at a bifurcation into a supernatant- and a cell-containing droplet. The method enables upconcentration of cells, cell washing,

There are currently no reliable biomarkers to predict clinical response to pharmacological treatments of depressive disorders. Peripheral blood 5-hydroxytryptamine (5-HT; serotonin) has been suggested as a biomarker of antidepressant treatment response, but there has not been an attempt to systematically summarize and evaluate the scientific evidence of this hypothesis. In this systematic review w

Rapporten presenterar resultaten av en studie som vi genomfört på uppdrag av Nätverket Idéburen Sektor Skåne och handlar om idéburna erfarenheter av samverkan med offentliga organisationer inom NAD. Syftet är att förstå hur strukturella förändringar och organisatoriska strategier har påverkat samverkan över tid. Tidsperioden sträcker sig från 2016 då vi genomförde en utvärdering av samverkan och 2

To study how mechanical factors influence the spread of cancer and the surrounding extracellular matrix (ECM), it is crucial that cancer cell populations be sorted without labels in relevant subpopulations with respect to mechanical properties. It is also important to confine subpopulations for long-term observation to track changes, in inherent properties of the subpopulations, and on the influen

We demonstrate that the detected emission intensity from YOYO-labeled DNA molecules confined in 180 nm deep Si/SiO2 nanofunnels changes significantly and not monotonically with the width of the funnel, an emission enhancement that is only detected for emitted light polarized parallel to the channel. We explain the enhancement effect as being due to optical phenomena in the channels. The enhancemen

Deterministic lateral displacement (DLD) is a powerful bimodal separation scheme [1] based on fluid flow through regular obstacle arrays that in its basic embodiment sends suspended particles in two different directions as a function of size. We show that without the need to seal devices and without the need for fluidic connections or pumps, particle separation can be achieved by the passive flow

Deterministic lateral displacement (DLD) is a powerful bimodal separation scheme [1] based on regular obstacle arrays that in its basic embodiment sends particles in two different directions as a function of size. We add functionality to the technique by including gravitational forces, as a perturbation to particles transported by fluid flow, and as a way of transporting the particles through a st

Conventional fractionation techniques fail to fully benefit from the variety in morphology and shape that is found among biological particles. Although light scattering in conventional FACS gives some information on the size and morphology of a particle, it is generally not capable of giving a definite number on specified dimensions of a small object. We demonstrate an approach where we select whi

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

Self-adaptation provides a principled way to deal with change during operation. As more systems with strict goals require self-adaptation, the need for guarantees in self-adaptive systems is becoming a high-priority concern. Designing adaptive software using principles from control theory has been identified as one of the approaches to provide guarantees. However, current solutions can only handle

We present a method to first laterally position microparticles inside droplets by acoustic forces and then split the droplet into three daughter droplets to achieve a 2+fold enrichment of microparticles inside the center droplet. We show that acoustic forces can be applied to both manipulate polystyrene beads (5 μm) and red blood cells inside droplets. The presented technology opens up for develop

This paper demonstrates a new acoustofluidic approach to enrich extremely dilute cell suspensions 1000 times and higher, at flow rates of ≥0.5 mL/min and higher, addressing some of the needs in rare cell processing and water quality monitoring.

The recent several years we developed the Scheimpflug lidar method. We combined an invention from the 19th century with modern optoelectronics such as diode lasers and CMOS array from the 21st century. The approach exceeds expectations of background suppression, sensitivity and resolution beyond known from time-of-flight lidars. We accomplished multiband elastic atmospheric lidars for resolving si
