Bending and Twisting Lattice Tilt in Strained Core-Shell Nanowires Revealed by Nanofocused X-ray Diffraction

We have investigated strained GaAs-GaInP core-shell nanowires using transmission electron microscopy and nanofocused scanning X-ray diffraction. Nominally identical growth conditions for each sample were achieved by using nanoimprint lithography to create wafer-scale arrays of Au seed particles. However, we observe large individual differences, with neighboring nanowires showing either straight, b

Development of novel therapies for Diamond-Blackfan Anemia

Diamond-Blackfan anemia is a congenital erythroid hypoplasia manifesting early inlife. In at least 60-70% of cases, DBA is caused by a functional haploinsufficiencyof genes encoding for ribosomal proteins. Approximately, 25% percent of patientshave mutations in the gene encoding ribosomal protein S19 (RPS19). Thehematological profile of DBA patients shows macrocytic anemia withreticulocytopenia, n

Neurodevelopmental disorders in young violent offenders : Overlap and background characteristics

Neurodevelopmental disorders (Attention-Deficit/Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), tic disorder, intellectual disability (ID)), in prison populations have received increased attention but the focus has generally been on one single condition leaving out the global picture. This study assessed the prevalence and overlap of neurodevelopmental disorders (NDD) in a consecuti

Personality factors and depression as predictors of hospital-based health care utilization following acute myocardial infarction

Background: Whether personality factors and depressive traits affect patients' utilization of health care following an acute myocardial infarction is relatively unknown. The aim of this study was to examine whether hospital-based health care utilization after a myocardial infarction was correlated with patients' personality factors and depressive symptoms. Methods: We studied 366 myocardial infarc

Use of moist oral snuff (snus) and pancreatic cancer : Pooled analysis of nine prospective observational studies

While smoking is a well-established risk factor for pancreatic cancer, the effect of smokeless tobacco is less well understood. We used pooled individual data from the Swedish Collaboration on Health Effects of Snus Use to assess the association between Swedish snus use and the risk of pancreatic cancer. A total of 424,152 male participants from nine cohort studies were followed up for risk of pan

Prescription of opioids for breathlessness in end-stage COPD : A national population-based study

Background: Low-dose opioids can relieve breathlessness but may be underused in late-stage COPD due to fear of complications, contributing to poor symptom control. Objectives: We aimed to study the period prevalence and indications of opioids actually prescribed in people with end-stage COPD. Methods: The study was a longitudinal, population-based study of patients starting long-term oxygen therap

Chronic breathlessness associated with poorer physical and mental health-related quality of life (SF-12) across all adult age groups

Little is known about the impact of chronic breathlessness (modified Medical Research Council (mMRC) score ≥2 for most days, at least three of the last six months) on health-related quality of life (Short Form-12 (SF-12)). 3005 adults from randomly selected households were interviewed face-to-face in South Australia. mMRC ≥2 community prevalence was 2.9%. Adjusted analyses showed clinically meanin

Lung transplantation and survival outcomes in patients with oxygen-dependent COPD with regard to their alpha-1 antitrypsin deficiency status

Background: Individuals with severe alpha-1 antitrypsin deficiency (AATD) have an increased risk of developing COPD. However, outcomes during long-term oxygen therapy (LTOT) in patients with severe AATD and hypoxemia are unknown. Patients and methods: This was a prospective, population-based, consecutive cohort study of patients on LTOT due to COPD in the period from January 1, 1987, to June 30, 2

Two-dimensional action spectroscopy of excitonic systems : Explicit simulation using a phase-modulation technique

Two-dimensional (2D) spectroscopy has been intensively used to study electronic and vibronic coherences in biological systems and semiconductors. This technique studies coherent as well as incoherent signals that arise from the nonlinear interaction of a sequence of laser pulses. In this paper we present a direct evaluation of the 2D signal based on elementary quantum kinetics in order to compare

Challenges with risk and vulnerability analyses : Strategies for integration in risk and crisis management

Today risk analyses are commonly used by authorities at national, regional and municipal levels in their work to prevent and prepare for crises. The analyses provide information about types of incidents that can occur and the potential consequences of these events. In Sweden and Norway it is mandatory for local authorities to conduct risk and vulnerability analyses and use them as an input in thei

Air pollution is associated with primary health care visits for asthma in Sweden : A case-crossover design with a distributed lag non-linear model

Background: Air pollution can increase the symptoms of asthma and has an acute effect on the number of emergency room visits and hospital admissions because of asthma, but little is known about the effect of air pollution on the number of primary health care (PHC) visits for asthma. Objective: To investigate the association between air pollution and the number of PHC visits for asthma in Scania, s

MYBPC3 hypertrophic cardiomyopathy can be detected by using advanced ECG in children and young adults

Introduction The conventional ECG is commonly used to screen for hypertrophic cardiomyopathy (HCM), but up to 25% of adults and possibly larger percentages of children with HCM have no distinctive abnormalities on the conventional ECG, whereas 5 to 15% of healthy young athletes do. Recently, a 5-min resting advanced 12-lead ECG test ("A-ECG score") showed superiority to pooled criteria from the st

Vital capacity and COPD : The Swedish CArdioPulmonary bioImage Study (SCAPIS)

Background: Spirometric diagnosis of chronic obstructive pulmonary disease (COPD) is based on the ratio of forced expiratory volume in 1 second (FEV1)/vital capacity (VC), either as a fixed value 1/VC ratio in a general population setting. The second aim was to evaluate the characteristics of subjects with COPD who obtained a higher SVC than FVC. Methods: Subjects (n=1,050) aged 50-64 years were i

Palladium seeded GaAs nanowires

In this work, we present a detailed investigation of the growth of palladium-seeded GaAs nanowires. Nanowires grown on GaAs (111)B substrates consist of three different morphologies, denoted as curly (containing multiple kinks), inclined (relative to the substrate, such as 〈001〉), and vertical. We show that the relative yield of the different types is controllable by a combination of V/III ratio a

Cardiovascular and antacid treatment and mortality in oxygen-dependent pulmonary fibrosis : A population-based longitudinal study

BACKGROUND AND OBJECTIVE: Severe idiopathic pulmonary fibrosis is associated with an increased risk of cardiovascular disease and gastro-oesophageal reflux, which may influence prognosis. We evaluated associations between cardiovascular and antacid medications, and mortality, in oxygen-dependent pulmonary fibrosis (PF) of unknown cause.METHODS: Prospective population-based study of adults starting

Generation of cortical neurons from human induced-pluripotent stem cells by biodegradable polymeric microspheres loaded with priming factors

Ischemic stroke is often associated with loss of cortical neurons leading to various neurological deficits. A cell replacement based on stem cell transplantation to repair the damaged brain requires the generation of specific neuronal subtypes. Recently, induced pluripotent stem cells have been used to generate various subtypes of neurons in vitro for transplantation in stroke-damaged brains. Howe
