Atomic-Resolution Spectrum Imaging of Semiconductor Nanowires

Over the past decade, III-V heterostructure nanowires have attracted a surge of attention for their application in novel semiconductor devices such as tunneling field-effect transistors (TFETs). The functionality of such devices critically depends on the specific atomic arrangement at the semiconductor heterointerfaces. However, most of the currently available characterization techniques lack suff

Sb Incorporation in Wurtzite and Zinc Blende InAs1-xSbx Branches on InAs Template Nanowires

The physical properties of material largely depend on their crystal structure. Nanowire growth is an important method for attaining metastable crystal structures in III-V semiconductors, giving access to advantageous electronic and surface properties. Antimonides are an exception, as growing metastable wurtzite structure has proven to be challenging. As a result, the properties of these materials

Interferon-β deficiency at asthma exacerbation promotes MLKL mediated necroptosis

Defective production of antiviral interferon (IFN)-β is thought to contribute to rhinovirus-induced asthma exacerbations. These exacerbations are associated with elevated lung levels of lactate dehydrogenase (LDH), indicating occurrence of cell necrosis. We thus hypothesized that reduced lung IFN-β could contribute to necrotic cell death in a model of asthma exacerbations. Wild-type and IFN-β-/- m

Alpha-1-microglobulin protects from heme induced placenta and kidney damage in a pregnant ewe model for preeclampsia

INTRODUCTION: Previous gene expression analysis have identified fetal hemoglobin (HbF) as a plausible etiological factor in preeclampsia. Free hemoglobin and its degradation products, e.g. heme, are known to cause oxidative stress, tissue damage, and vaso-constriction, typical findings in preeclampsia.OBJECTIVE: To study alpha-1-microglobulin (A1M), an endogenous radical scavenger and heme-binder,

PERson-centredness in hypertension management using information technology (PERHIT) : a protocol for a randomised controlled trial in primary health care

Purpose: For primary health care (PHC), hypertension is the number one diagnosis for planned health care visits. The treatment of high blood pressure (BP) and its consequences constitutes a substantial economic burden. In spite of efficient antihypertensive medications, a low percentage of patients reach a well-controlled BP. The PERson-centredness in Hypertension management using Information Tech

Psychiatric disorders and cardiovascular diseases during the diagnostic workup of potential breast cancer : a population-based cohort study in Skåne, Sweden

BACKGROUND: An increasing number of women are evaluated for potential breast cancer and may experience mental distress during evaluation. We aim to assess the risks of psychiatric disorders and cardiovascular diseases during the diagnostic workup of potential breast cancer.METHODS: All women with a new diagnosis of unspecified lump in breast (N = 15,714), benign tumor or breast cancer in situ (N =

Electrical control of spins and giant g-factors in ring-like coupled quantum dots

Emerging theoretical concepts for quantum technologies have driven a continuous search for structures where a quantum state, such as spin, can be manipulated efficiently. Central to many concepts is the ability to control a system by electric and magnetic fields, relying on strong spin-orbit interaction and a large g-factor. Here, we present a mechanism for spin and orbital manipulation using smal

Weight and height separated provide better understanding than BMI on the risk of revision after total knee arthroplasty : report of 107,228 primary total knee arthroplasties from the Swedish Knee Arthroplasty Register 2009–2017

Background and purpose — Obesity defined as increased BMI is commonly associated with higher revision rates following total knee arthroplasty (TKA). We examined the effect of BMI on the rate of revision after TKA, for both infection and other reasons, and analyzed weight and height separately to provide better understanding of the risk profile. Patients and methods — The Swedish national knee arth

Renal function in a large cohort of metformin treated patients with type 2 diabetes mellitus

Objectives To survey renal function in a defined population on metformin treatment. Methods All patients in the city of Malmö who collected at least three prescriptions of metformin during two years were identified from a central registry at the National Board of Health and Welfare in Sweden. Estimated glomerular filtration rate (eGFR), from the Chronic Kidney Disease Epidemiology Collaboration (C

Dread and Risk Elimination Premium for the Value of a Statistical Life

The value of a statistical life (VSL) is a widely used measure for the value of mortality risk reduction. As VSL should reflect preferences and attitudes to risk, there are reasons to believe that it varies depending on the type of risk involved. It has been argued that cancer should be considered a "dread disease," which supports the use of a "cancer premium." The objective of this study is to in

Enhancement of HFE-7200 pool boiling heat transfer on copper surfaces with nanoparticle coatings

Saturated pool boiling heat transfer of HFE-7200 is investigated experimentally on copper surfaces with nanoparticle coatings at atmospheric pressure. The coatings are generated by an electrophoretic deposition method. Two modified surfaces are prepared with Cu-Zinc nanoparticles of 0.3 mg and 0.6 mg, respectively. During the deposition, ethanol works as the solvent while the electrical potential

Fabrication of a silver nanoparticle-coated collagen membrane with anti-bacterial and anti-inflammatory activities for guided bone regeneration

Alveolar bone loss is a common problem that affects dental implant placement. A barrier between the bone substitute and gingiva that can prevent fibro-tissue ingrowth, bacterial infection and induce bone formation is a key factor in improving the success of alveolar ridge reconstruction. This study aims to develop a bioactive collagen barrier material for guided bone regeneration, that is coupled

Lower extremity function in patients with early rheumatoid arthritis during the first five years, and relation to other disease parameters

Objective: The objective of this study was to investigate lower extremity function in early rheumatoid arthritis (RA) and assess its relation to other disease parameters. Methods: An inception cohort (recruited in 1995–2005) of patients with early RA was followed according to a structured protocol. Lower extremity function was investigated at inclusion and after 1, 2, and 5 years using the Index o

In situ analysis of catalyst composition during gold catalyzed GaAs nanowire growth

Semiconductor nanowires offer the opportunity to incorporate novel structures and functionality into electronic and optoelectronic devices. A clear understanding of the nanowire growth mechanism is essential for well-controlled growth of structures with desired properties, but the understanding is currently limited by a lack of empirical measurements of important parameters during growth, such as

Sintering of binderless cubic boron nitride and its modification by β-Si3N4 additive for hard machining applications

This study present the results of HP-HT sintering, microstructure, properties, and performance of binderless cBN tool material. Within the investigated sintering temperature range of 1900–2600 °C the optimum was found to be 2200–2300 °C. Lower temperature results in incomplete diffusion bonding between cBN grains, while higher temperature results in high degree of recrystallization of initial stru

Disease Modification by Combinatorial Single Vector Gene Therapy : A Preclinical Translational Study in Epilepsy

Gene therapy has been suggested as a plausible novel approach to achieve seizure control in patients with focal epilepsy that do not adequately respond to pharmacological treatment. We investigated the seizure-suppressant potential of combinatorial neuropeptide Y and Y2 receptor single vector gene therapy based on adeno-associated virus serotype 1 (AAV1) in rats. First, a dose-response study in th

Aggregation-Induced Emission in a Polymeric Photovoltaic Donor Material

In this work, we report the aggregation-induced emission in a polymeric donor material poly(bis(2-butyloctyl)[2,2′:5′,2″-terthiophene]-4,4″-dicarboxylate-5,5′-diyl-vinylene) (PTVT-T), which exhibits a high device performance for the application of photovoltaics. Time-dependent density functional theory calculations and steady-state and time-resolved spectroscopy have been employed to reveal the un

Prenatal exposure to phthalates and gender-specific play behavior at seven years of age in the SELMA study

Background: A growing body of evidence shows that prenatal exposure to phthalates affects child development. Since many phthalates have been shown to alter endocrine signaling, they may influence reproductive development, neurodevelopment, and child behavior. Indeed, a few studies reported associations between prenatal phthalate exposure and gender-specific play behavior. However, evidence for thi
