Measurements of the spin-orbit interaction and Landé g factor in a pure-phase InAs nanowire double quantum dot in the Pauli spin-blockade regime

We demonstrate direct measurements of the spin-orbit interaction and Landé g factors in a semiconductor nanowire double quantum dot. The device is made from a single-crystal pure-phase InAs nanowire on top of an array of finger gates on a Si/SiO2 substrate and the measurements are performed in the Pauli spin-blockade regime. It is found that the double quantum dot exhibits a large singlet-triplet

Frequency and patterns of reassortment in natural influenza A virus infection in a reservoir host

Influenza A viruses (IAV) can dramatically alter both genotype and phenotype at a rapid rate as a product of co-infection and reassortment. Avian IAV exhibit high levels of phylogenetic incongruence, suggesting high levels of reassortment in the virus reservoir. Using a natural-experimental system, we reconstructed relationships amongst 92 viruses across 15 subtypes from 10 Mallards in an autumn s

A FISH-based method for assessment of HER-2 amplification status in breast cancer circulating tumor cells following CellSearch isolation

Amplification of the HER-2/neu (HER-2) proto-oncogene occurs in 10%–15% of primary breast cancer, leading to an activated HER-2 receptor, augmenting growth of cancer cells. Tumor classification is determined in primary tumor tissue and metastatic biopsies. However, malignant cells tend to alter their phenotype during disease progression. Circulating tumor cell (CTC) analysis may serve as an altern

Macrophage colony-stimulating factor receptor marks and regulates a fetal myeloid-primed B-cell progenitor in mice

Although it is well established that unique B-cell lineages develop through distinct regulatory mechanisms during embryonic development, much less is understood about the differences between embryonic and adult B-cell progenitor cells, likely to underpin the genetics and biology of infant and childhood PreB acute lymphoblastic leukemia (PreB-ALL), initiated by distinct leukemia-initiating transloc

Early vascular ageing as a new model to understand hypertension and arterial disease

Hypertension is a major cardiovascular risk factor and can be treated. The cardiovascular risk associated with hypertension, however, cannot be fully reversed by treatment with blood pressure-lowering drugs. One reason could be that not all risk factors are addressed at the same time, but another reason could well be that structural changes and remodelling of the arterial wall are not diminished n

Bilateral Arthrodesis of the Ankle Joint : Self-Reported Outcomes in 35 Patients From the Swedish Ankle Registry

Bilateral ankle arthrodesis is seldom performed, and results concerning the outcome and satisfaction can only sparsely be found in published studies. We analyzed the data from 35 patients who had undergone bilateral ankle arthrodesis in the Swedish Ankle Registry using patient-reported generic and region-specific outcome measures. Of 36 talocrural arthrodeses and 34 tibio-talar-calcaneal arthrodes

Cryopreserved or fresh mesenchymal stromal cells : Only a matter of taste or key to unleash the full clinical potential of MSC therapy?

Mesenchymal stromal cells (MSCs) harbor great therapeutic potential for numerous diseases. From early clinical trials, success and failure analysis, bench-to-bedside and back-to-bench approaches, there has been a great gain in knowledge, still leaving a number of questions to be answered regarding optimal manufacturing and quality of MSCs for clinical application. For treatment of many acute indic

Fe N-Heterocyclic Carbene Complexes as Promising Photosensitizers

ConspectusThe photophysics and photochemistry of transition metal complexes (TMCs) has long been a hot field of interdisciplinary research. Rich metal-based redox processes, together with a high variety in electronic configurations and excited-state dynamics, have rendered TMCs excellent candidates for interconversion between light, chemical, and electrical energies in intramolecular, supramolecul

Fetal to Adult Hematopoiesis with the “Flk” of a Switch

Blood development relies on discrete stem and progenitor cell populations with unclear lineage relationships and distinct functional characteristics that change during ontogeny. In this issue of Cell Stem Cell, Beaudin et al. (2016) identify a hematopoietic stem cell population with fetal characteristics that is developmentally restricted yet capable of long-term multi-lineage reconstitution upon

The androgen receptor gene CAG repeat in relation to 4-year changes in androgen-sensitive endpoints in community-dwelling older European men

Context: The androgen receptor (AR) gene exon 1 CAG repeat length has been proposed to be a determinant of between-individual variations in androgen action in target tissues, which might regulate phenotypic differences of human ageing. However, findings on its phenotypic effects are inconclusive. Objective: To assess whether the AR CAG repeat length is associated with longitudinal changes in endpo

Cardiovascular fitness in young males and risk of unprovoked venous thromboembolism in adulthood

Background: Whether high cardiovascular fitness is associated with reduced risk of venous thromboembolism (VTE) is unknown. The present study aims to determine whether high cardiovascular fitness reduces the risk of VTE. Methods: A Swedish cohort of male conscripts (n = 773,925) born in 1954–1970 with no history of previous VTE were followed from enlistment (1972–1990) until 2010. Data on cardiova

DETAILED ABUNDANCE ANALYSIS of A METAL-POOR GIANT in the GALACTIC CENTER

We report the first results from our program to examine the metallicity distribution of the Milky Way nuclear star cluster connected to Sgr A∗, with the goal of inferring the star formation and enrichment history of this system, as well as its connection and relationship with the central 100 pc of the bulge/bar system. We present the first high-resolution (R ∼ 24,000), detailed abundance analysis

Optical characterization of agricultural pest insects : a methodological study in the spectral and time domains

Identification of agricultural pest insects is an important aspect in insect research and agricultural monitoring. We have performed a methodological study of how spectroscopic techniques and wing-beat frequency analysis might provide relevant information. An optical system based on the combination of close-range remote sensing and reflectance spectroscopy was developed to study the optical charac

Polymeric material comprising ortho-positioned acidic groups

The present invention relates to a polymeric material comprising structural elements of the following general formula (I): wherein Ph1, Ph2 and Ph3 independently are phenylenes comprising acidic groups with or without a spacer or salts thereof; X1, X2, X3 and X4 independently are O, S, SO, SO2, or a direct bond and wherein X1 also may be H termination when Formula (I) relates to side chains of the

Long-term dynamics of the state in francophone West Africa : Fiscal capacity pathways 1850–2010

This study identifies and analyses common and country-specific patterns in the evolution of the state in francophone West Africa through a detailed comparison of long-term fiscal capacity between Benin, Côte d’Ivoire, Niger and Senegal. The study finds common patterns of long-term growth in fiscal capacity in the four countries since the early colonial period, which is indicative of a process of l

Critical Care Management after Cardiac Arrest

Sudden cardiac arrest is a devastating event with high mortality and substantial morbidity among survivors. Early recognition and intervention to restore circulation is the primary goal; once that is achieved, the path toward a meaningful recovery starts. Initial in-hospital care is focused on emergency cardiac care, but soon there is a change to a more brain-oriented critical care including targe
