Quantification of blood flow in the fetus with cardiovascular magnetic resonance imaging using Doppler ultrasound gating : validation against metric optimized gating

INTRODUCTION: Fetal cardiovascular magnetic resonance (CMR) imaging is used clinically and for research, but has been previously limited due to lack of direct gating methods. A CMR-compatible Doppler ultrasound (DUS) gating device has resolved this. However, the DUS-gating method is not validated against the current reference method for fetal phase-contrast blood flow measurements, metric optimize

Post-socialist moral economies of consumption as socially embedded sites of moral tension

Consumption was one of the spheres of everyday life shaken and remoulded by the collapse of socialist regimes at the end of the 20th century. Especially in times of rapid change, a moral economies lens is a fruitful means to understand the contentious moral landscape and moral tensions that pervade consumption behaviour, norms and discourse. Important areas of consideration in post-socialist socie

Searching for Atrial Fibrillation Poststroke : A White Paper of the AF-SCREEN International Collaboration

Cardiac thromboembolism attributed to atrial fibrillation (AF) is responsible for up to one-third of ischemic strokes. Stroke may be the first manifestation of previously undetected AF. Given the efficacy of oral anticoagulants in preventing AF-related ischemic strokes, strategies of searching for AF after a stroke using ECG monitoring followed by oral anticoagulation (OAC) treatment have been pro

Thermodynamic uncertainty relations including measurement and feedback

Thermodynamic uncertainty relations quantify how the signal-to-noise ratio of a given observable is constrained by dissipation. Fluctuation relations generalize the second law of thermodynamics to stochastic processes. We show that any fluctuation relation directly implies a thermodynamic uncertainty relation, considerably increasing their range of applicability. In particular, we extend thermodyn

Conductive and enzyme-like silk fibers for soft sensing application

A combination of supercritical carbon dioxide (scCO2) impregnation of pyrrole and sonochemical transformation of permanganate (KMnO4) was used to impart conductive and catalytic properties to silk fibers. The results indicated that the conductivity (from polypyrrole –PPy) and catalytic activities (from manganese dioxide –MnO2) were independent and complementary within the processing parameters use

Apolipoprotein M-bound sphingosine-1-phosphate regulates blood-brain barrier paracellular permeability and transcytosis

The blood-brain barrier (BBB) is formed by the endothelial cells lining cerebral microvessels, but how blood-borne signaling molecules influence permeability is incompletely understood. We here examined how the apolipoprotein M (apoM)-bound sphingosine 1-phosphate (S1P) signaling pathway affects the BBB in different categories of cerebral microvessels using ApoM deficient mice (Apom-/-). We used t

Performing the Other : Report on workshops on Copying and Imitating

Performing The Other. Report on workshops on observing and imitatingThe lecture will present the experience, results and challenges arising within a series of workshops that were investigating the role of observation, copying and imitation in the actor’s work, activities close to Brecht’s aesthetic focus. Claiming that “people will observe you, in order to investigate how well you have observed”,

Imitation as vehicle – and memory as hindrance

What is the relationship between identity, representation and memory in contemporary performance practices? Does memory function as a basic tool in artist’s work or can it also be regarded as a hindrance?In current performance art, identity is often defined as an accumulation of one’s embodied experience and memory. The artist’s body can be seen as an archive which is re-enacted in the encounter w

African Economic Growth 1900-50: Historical National Accounts for British Colonial Africa

The study of growth in African economies during the 20th Century is hampered by the lack of historical GDP estimates. There has been some backward projections, and country case studies, but despite the available data historical national accounts has not yet been assembled. This paper provides GDP estimates for some former British colonies between 1900 – 1950. The estimates indicate faster growth a

The Problems of Economic Data in Africa

The study of economic development in African countries is facing a basic problem of lack of reliable data and statistics. These problems of economic data are best addressed under three main categories: design, capacity, and politics. The focus is on gross domestic product (GDP), but the relevance goes beyond GDP statistics because the aggregate of GDP requires economic data on all sectors of the e

Electrochemical Synthesis of Ammonia Based on a Perovskite LaCrO3 Catalyst

Electrochemical synthesis of ammonia through the nitrogen reduction reaction (NRR) has the possibility to revolutionize our production of ammonia and to save our planet from both emissions and large energy consumption. In this study, a perovskite structured lanthanum chromite catalyst (LaCrO3) is synthesized, characterized as well as electrochemically evaluated for NRR. The highest ammonia yield i

Quantitative Methods and Economic Statistical Sources for African History

The mode of enquiry in African economic history has changed quite radically in recent years. In 1987, Patrick Manning surveyed practices and databases in African economic history and compared empirical strategies of scholars who studied the African past. Current practice, which A. G. Hopkins called “new African economic history,” incorporates econometric methods. The specific methods chosen and th

Controversy, Facts and Assumptions: Lessons from Estimating Long Term Growth in Nigeria, 1900–2007

This article contributes to the debates surrounding "New African Economic History" by exploring the feasibility of constructing a time series of economic growth in Nigeria spanning the whole twentieth century. Currently most datasets for African economies only go back to 1960. The sources for their creation exist, but these valuable colonial data remain underutilized. This is an exploratory paper

Interaction with the host : the role of fibronectin and extracellular matrix proteins in the adhesion of Gram-negative bacteria

The capacity of pathogenic microorganisms to adhere to host cells and avoid clearance by the host immune system is the initial and most decisive step leading to infections. Bacteria have developed different strategies to attach to diverse host surface structures. One important strategy is the adhesion to extracellular matrix (ECM) proteins (e.g., collagen, fibronectin, laminin) that are highly abu

Female sex, high soluble CD163, and low HDL-cholesterol were associated with high galectin-3 binding protein in type 1 diabetes

Background: Galectin-3 binding protein (Gal3BP), sCD163, galectin-3, and depression have been linked to cardiovascular disease and mortality. In patients with type 1 diabetes, female sex has also been linked to cardiovascular disease and mortality. The aim was to explore whether female sex, sCD163, galectin-3, and depression were associated with Gal3BP in patients with type 1 diabetes. We adjusted

Effect of nicotine 6 mg gum on urges to smoke, a randomized clinical trial

Background: Ability to manage urges to smoke is fundamental to maximizing the chances of success in smoking cessation. Previous studies have linked a higher dose of nicotine in nicotine replacement therapy to a higher success rate for smoking cessation. Thus, this study was performed to compare relief of urges to smoke, up until 5 h following treatment with a new 6 mg nicotine gum versus currently

Being the next of kin of an older person living in a nursing home : an interview study about quality of life

BACKGROUND: The length of stay in nursing homes before death in Sweden has significantly decreased, and nearly one-third of people die within 6 weeks of entering a nursing home. Support for the next of kin is one of the cornerstones of palliative care, but the principles are not always adhered to as recommended when caring for the elderly, which can affect the quality of life of their next of kin.
