Multinodal high throughput acoustic trapping of exosomes from urine samples
We report a new design of an acoustophoretic trapping device with greatly increased capacity and throughput, compared to current commercial systems. Acoustic trapping enables nanoparticle and exosome enrichment without the need for ultracentrifugation. The commercial acoustic trapping technology, AcouTrap (AcouSort AB), typically operates at flow rates < 50 μl/min which limits processing of larger
Exit, Voice and Consensus- A Legal and Political Analysis of the Emergency Brake in EU Criminal Policy
This article presents a political and legal analysis of the emergency brake in criminal law in Articles 82(3) and 83(3) TFEU. It suggests that the emergency brake offers a powerful discretionary prerogative for Member States seeking to protect the integrity of their criminal justice systems. This strong legal shield for Member States in the form of a ‘quasi-veto’ is contrasted with a tendency to d
Long DNA isolation and imaging using lateral displacement arrays integrated with DNA combing
We demonstrate proof of principle of an efficient and simple method combining sample preparation and stretching of DNA in a single device that can be used as basis for an integrated portable system for optical DNA mapping. An important bottleneck for DNA mapping, as well as for other methods, is the isolation of long DNA molecules from a background of contaminants such as shorter DNA fragments, dy
Viable/non-viable cell assay using electrokinetic deterministic lateral displacement
To evaluate the effect of antibiotic drugs, it is important that the cells that are killed can be sorted from the cells that are resistant to the antibiotics. Here we report a simple label-free method for the continuous separation of viable/non-viable cells using Electrokinetic Deterministic Lateral Displacement. In general, this opens up for continuous sorting of a population of cells that is hom
The separation of nano-sized particles in micro-scaled post arrays
The precise separation of nanoscale particles has proven challenging due to diffusion and the need to use nanoscale devices. We show the separation of particles in the 100 nm size range in Deterministic Lateral Displacement (DLD) devices with feature sizes in the 10 µm size range. We achieve this using Dielectrophoretic (DEP) forces, generated between the metal coated posts that act as active elec
The separation and identification of parasite eggs from horse feces
Freely grazing horses are at risk of infection by parasites such as Parascaris equorum (roundworm), Strongylus spp. (large bloodworms), Cyathostomes (small bloodworms), and Anoplochephala perfoliata (tapeworms). Mixed infections are common and diagnosis is based on demonstrations of eggs in feces followed by identification of larvae after fecal culture. Drug resistance is a growing problem, not le
Bacterial identification by optical mapping of genomic DNA in nanofluidic channels
A variety of pathogenic bacteria can infect humans and the increase in bacteria resistant to common antibiotics is a large threat to human health worldwide. This work presents a method, based on optical DNA mapping (ODM) in nanofluidic channels, that can detect the type of bacterial present in a sample by matching the obtained maps of large DNA molecules to a database of fully assembled bacterial
Rapid fabrication of PMMA/PET-E/PMMA for thermoplastic microfluidic membrane devices
We present a method to rapidly fabricate a large number of thermoplastic microfluidic systems where horizontal microchannels are separated by a porous membrane for modelling biological barriers. We optimize and combine solvent bonding, milling and laser cutting to fabricate in excess of 100 devices in two days. The optimized protocol relies on a commercial solvent blend, retention grooves for solv
Improvement of computational fluid dynamics simulations of flow in patients with total cavo pulmonary connection and predicting interventional outcomes
PP039. ETK/BMX and renin-angiotensin system (RAS) components are differentially expressed in renal tissue in both normal and preeclamptic pregnancy
INTRODUCTION: Renal ETK/BMX activity is reduced in preeclampsia. Systemic RAS has been studied in preeclampsia; the renal RAS has not. None of the proteins in either pathway have previously been located in renal tissue from human pregnancy.OBJECTIVES: To determine renal expression and distribution of proteins involved in the ETK/BMX and RAS pathways in normal and preeclamptic pregnancy.METHODS: Li
PP038. Renal ETK/BMX activation decreased in preeclampsia
INTRODUCTION: Vascular endothelial growth factors (VEGF's) are essential to angiogenesis and play a central role in the pathophysiology of preeclampsia. Specifically, antagonists of VEGFR2 cause a preeclampsia-like syndrome, in humans and rats[1]. ETK/BMX is a receptor tyrosine kinase (RTK) which induces VEGF expression and forms a complex with VEGFR2, whereby VEGF and TNF can induce a reciprocal

Multi-Level Gas Monitoring : A New Approach in Earthquake Research
Fluid anomalies were often considered as possible precursors before earthquakes. However, fluid properties at the surface can change for a variety of reasons, including environmental changes near the surface, the response of the superficial fluid system to loads associated with the mechanical nucleation of earthquake fractures, or as a result of transients in fluid flow from the depths. A key prob

Effect of intraoperative nerve monitoring on postoperative vocal cord palsy rates after thyroidectomy : European multicentre registry-based study
BACKGROUND: Intraoperative nerve monitoring (IONM) of the recurrent laryngeal nerve (RLN) predicts the risk of vocal cord palsy (VCP). IONM can be used to adapt the surgical strategy in order to prevent bilateral VCP and associated morbidity. Controversial results have been reported in the literature for the effect of IONM on rates of VCP, and large multicentre studies are required for elucidation
A tale of planet formation : From dust to planets
The characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved. In this review, we first summarize the cutting-edge states of the exoplanet and disk observations. We further present a comprehensive panoptic view of modern core accret
High-Speed Analog-to-Digital Converters in CMOS
The Analog to Digital (A/D) Converters (ADC) are vital components in high-performance radio devices. In the receiver end, the signal received by the analog front-end can not be directly analyzed by the digital core, thus requiring high-performance ADC circuits acting as bridges connecting the analog and digital domain. These circuits are integrated into Complementary Metal-Oxide-Semiconductor (CMO
Drought legacy affects microbial community trait distributions related to moisture along a savanna‐grassland precipitation gradient
Ecosystem models commonly use stable‐state assumptions to predict responses of soil microbial functions to environmental change. However, past climatic conditions can shape microbial functional responses resulting in a ‘legacy effect’. For instance, exposure to drier conditions in the field may shape how soil microbial communities respond to subsequent drought and drying and rewetting (DRW) event
