Choice Awareness and Manipulation Blindness : A cognitive semiotic exploration of choice-making
Tunable separation and DNA manipulation in metal coated pillar arrays
Implementing electrically connected metal-coated posts in a Deterministic Lateral Displacement (DLD) device and applying electric fields, we use electrokinetics to achieve tunable particle separations and to trap and manipulate DNA. The strength of DLD stems from its typically binary behavior. Particles move in one out of two trajectories based on their effective size. For particles that are close
Measuring cancer cell compressibility by acoustophoresis separation experiments
We present a new experimental method for the measurement of the compressibility of cells by analysis of free flow acoustophoresis separation data.
ACouWash : A standalone instrument for the washing, separation and enrichment of cells.
We developed the AcouWash (Figures 1 and 2), a benchtop instrument for flow-through cell and particle separation by acoustophoresis. Building on previous research [1-4] AcouWash can re-suspend cells in new medium, separate cells based on size or acoustic properties, or enrich cells, Figure 3. We present our initial evaluation of AcouWash regarding size-based separation of particles, cell washing,
Method for selecting optimal operation frequencies in bulk acoustophoretic devices
We report a new method to select the optimal actuation frequencies in bulk acoustophoresis devices, by means of differential impedance spectrum analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra is rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance, Fig. 1a, why direct measurement of the piezo impeda

Integrated on-chip system for DNA purification, labelling and surface stretching
We report a simplified, integrated and more efficient way of preparing DNA for analysis. We have developed a microfluidic platform that can purify DNA and subsequently label and stretch it on a surface. We have successfully extracted DNA from a gel-filled microfluidic channel using electrophoresis and subsequently stretched the DNA linearly by absorption to either a hydrophobic or a positively-cha
The evolution of early symbolic behavior in Homo sapiens
How did human symbolic behavior evolve? Dating up to about 100,000 y ago, the engraved ochre and ostrich eggshell fragments from the South African Blombos Cave and Diepkloof Rock Shelter provide a unique window into presumed early symbolic traditions of Homo sapiens and how they evolved over a period of more than 30,000 y. Using the engravings as stimuli, we report five experiments which suggest t
Analysis of DNA methylation patterns in the tumor immune microenvironment of metastatic melanoma
The presence of immune cells in the tumor microenvironment has been associated with response to immunotherapies across several cancer types, including melanoma. Despite its therapeutic relevance, characterization of the melanoma immune microenvironments remains insufficiently explored. To distinguish the immune microenvironment in a cohort of 180 metastatic melanoma clinical specimens, we develope
Manganese oxide functionalized silk fibers for enzyme mimics application
The inorganic metal or metal-oxide nanoparticles (NPs) that mimic enzymes are of great interest due to improved physical and chemical properties compared with native enzymes. Here, we report that manganese dioxide (MnO2)-Silk exhibit catalase, oxidase, and peroxidase-like activities. The MnO2-Silk hybrid fibers effectively decomposed hydrogen peroxide (H2O2) and oxidized the typical horseradish pe
Transcriptome-wide association study of breast cancer risk by estrogen-receptor status.
Previous transcriptome-wide association studies (TWAS) have identified breast cancer risk genes by integrating data from expression quantitative loci and genome-wide association studies (GWAS), but analyses of breast cancer subtype-specific associations have been limited. In this study, we conducted a TWAS using gene expression data from GTEx and summary statistics from the hitherto largest GWAS m
Risk-reducing salpingo-oophorectomy, natural menopause, and breast cancer risk: an international prospective cohort of BRCA1 and BRCA2 mutation carriers
BACKGROUND: The effect of risk-reducing salpingo-oophorectomy (RRSO) on breast cancer risk for BRCA1 and BRCA2 mutation carriers is uncertain. Retrospective analyses have suggested a protective effect but may be substantially biased. Prospective studies have had limited power, particularly for BRCA2 mutation carriers. Further, previous studies have not considered the effect of RRSO in the context

Interactions between University Spin-Offs and Academia : A Dynamic Perspective
Purpose: This paper aims to investigate the nature and dynamics of the interaction between university spin-offs (USOs) and academia. Design/methodology/approach: The theoretical framework is grounded in an interactive view based on the industrial marketing and purchasing literature on USOs and their development. The concepts of activity links, resource ties and actor bonds are used as a starting p

Copyright in a borderless online environment
In October 2011, the Institute for Legal Research (Institutet för Rättsvetenskaplig Forskning) organized a symposium to explore various aspects of the theme copyright in a borderless online environment. The symposium gathered prominent Nordic and International scholars and practitioners in the field of copyright and international private law. This volume is in essence the collection of papers pres
