Optical mapping relies on the preparation of fluorescent DNA. DNA must be imaged with good signal to noise and therefore the background of unwanted DNA fragments, fluorescent dyes and other reagents need to be removed. We use deterministic lateral displacement to separate 48.5 kbp DNA from < 10 kbp DNA. We also show the removal of 48.5 kbp DNA fragments from a background of fluorescent ATTO647N mo

We study the importance of teacher subject knowledge for student performance in Sub-Saharan Africa using unique international assessment data for sixth-grade students and their teachers. To circumvent bias due to unobserved student heterogeneity, we exploit variation within students across math and reading. Teacher subject knowledge has a modest impact on student performance. Exploiting vast cross

Platsen är London, året är 2036. Miljoner människor dör av infektioner som tidigare kunnat behandlas. Antibiotikan är inte längre verksam mot vanliga infektioner och rädslan sprider sig som ett gift i samhället. Demokratin hotas, politiker mördas och terrordåd drabbar staden. Populister spelar på folkets känslor med slagord som ”Making Britain strong again” och förnekar vetenskapliga upptäckter so

Purpose — We wanted to examine the potential of the Scandinavian Sarcoma Group (SSG) Central Register, and evaluate referral and treatment practice for soft-tissue sarcomas in the extremities and trunk wall (STS) in the Nordic countries. Background — Based on incidence rates from the literature, 8,150 (7,000–9,300) cases of STS of the extremity and trunk wall should have been diagnosed in Norway,

This article highlights the role recycling played in clothes culture as found in examples from Lady Märta Helena Reenstierna’s diary (1793–1839) and garments in Swedish museum collections. By using approaches from Textile Studies, clothes are seen in a lifecycle perspective rather than regarding fashion as luxury consumption focusing on the moment of purchase. Recycling as a concept allows central

Evaluation of Specific Absorption Rate (SAR) for multiple antenna systems is expected with the upcoming deployment of LTE Advanced, where multi-antennas are excited in both uplink and downlink. In this work, the influence of different antenna locations and antenna types was investigated for stand-alone SAR and simultaneous SAR, to provide some guidelines for antenna design in multi-antenna handset

RF and DC characterization of vertical InAs nanowire MOSFET on Si substrates are presented. Nanowire arrays are epitaxially integrated on Si substrates by use of a thin InAs buffer layer. For device fabrication, high-k HfO2 gate dielectric and wrap-gates are used. Post-deposition annealing of the high-k is evaluated by comparing one annealed and one not-annealed sample. The annealed sample show be

Therapy directed against oncogenic FLT3 has been shown to induce response in patients with acute myeloid leukemia (AML), but these responses are almost always transient. To address the mechanism of FLT3 inhibitor resistance, we generated two resistant AML cell lines by sustained treatment with the FLT3 inhibitor sorafenib. Parental cell lines carry the FLT3-ITD (tandem duplication) mutation and ar

Guayusa (Ilex guayusa) is a native tree of the western Amazon region grown by indigenou farmers in traditional agroforestry systems. Its leaves are used as a drink similar to tea, which is now commercialized and marketed outside of the Amazon. To assess the impacts from theearly stages of commercial guayusa production, we conducted interviews in four commercial guayusa-producing communities with i

We make Deterministic Lateral Displacement (DLD) flexible by combining it with AC electrokinetics.

Mesoscopic simulations with two-dimensional (2D) models have been performed to elucidate the dynamics of deformable red blood cells (RBCs) in deterministic lateral displacement (DLD) devices. Several shapes of posts, including circular, diamond, square and triangular structures and RBCs with different rigidities are considered. In comparison to rigid particles, the deformable RBCs exhibit much mor

Objective: Previous research has indicated that components of the metabolic syndrome (MetS), such as hyperglycemia and hypertension, are negatively associated with cognition. However, evidence that MetS itself is related to cognitive performance has been inconsistent. This longitudinal study investigates whether MetS or its components affect cognitive decline in aging men and whether any interacti

Background/Objective To demonstrate therapeutic equivalence of terbutaline via two different Turbuhaler® devices by evaluating its protective effect against methacholine-induced bronchoconstriction in stable asthma. Methods In this double-blind, double-dummy, multicentre, single-dose, 4-way crossover study, patients with stable mild-to-moderate asthma (FEV1 ≥80% predicted) were randomised to 0.5 o

Introduction. Elder abuse is often a hidden phenomenon and, in many cases, screening practices are difficult to implement among older people with dementia. The Caregiver Abuse Screen (CASE) is a useful tool which is administered to family caregivers for detecting their potential abusive behavior. Objectives. To validate the Italian version of the CASE tool in the context of family caregiving of ol

The energy justice framework serves as an important decision-making tool in order to understand how different principles of justice can inform energy systems and policies. The realization of the urgency of providing modern energy technology and services particularly to rural areas has prompted both the Nepalese government and development institutions to focus on community-run renewable energy faci
