A randomised, open-label trial to assess the optimal treatment strategy in early diffuse cutaneous systemic sclerosis : The UPSIDE study protocol

Introduction Systemic sclerosis (SSc) is a chronic, autoimmune connective tissue disease associated with high morbidity and mortality, especially in diffuse cutaneous SSc (dcSSc). Currently, there are several treatments available in early dcSSc that aim to change the disease course, including immunosuppressive agents and autologous haematopoietic stem cell transplantation (HSCT). HSCT has been ado

An analysis of ammonia synthesis by the model of Selective Energy Transfer (SET)

The SET theory implies that energy is transferred from the catalyst system via infrared radiation to the molecules that are supposed to react. In previous investigations it has been demonstrated that the activation of the reacting species-as long as the molecules are infrared active-can occur at low adsorption strength. However, for molecules that are IR inactive, e.g. dinitrogen, this is not poss

Utility of Fetal Cardiovascular Magnetic Resonance for Prenatal Diagnosis of Complex Congenital Heart Defects

Importance: Prenatal diagnosis of complex congenital heart defects reduces mortality and morbidity in affected infants. However, fetal echocardiography can be limited by poor acoustic windows, and there is a need for improved diagnostic methods.Objective: To assess the clinical utility of fetal cardiovascular magnetic resonance imaging in cases in which fetal echocardiography could not visualize a

Ab initio electronic factors of the A and B hyperfine structure constants for the 5s25p6s1,3P01 states in Sn I

Large-scale ab initio calculations of the electronic contribution to the electric quadrupole hyperfine constant B were performed for the 5s25p6s1,3Po1 excited states of neutral tin. To probe the sensitivity of B to different electron correlation effects, three sets of variational multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction calculations employing different strat

Exploring strategies to improve volumetric hydrogen productivities of Caldicellulosiruptor species

Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. Thermophilic bacteria belonging to the genus of Caldicell

The azure European flag with the 12 golden stars is a well-known symbol of 'European unity', just as many will recognize myths and tales of how the European Union (EU) is our guarantor of peace and prosperity in Europe.But how are symbols and myths about the EU spread and perceived? How do the European Commission, the European Parliament and the Council of Ministers affect the spread and perceptio

Pepsin-like aspartic proteases (PAPs) as model systems for combining biomolecular simulation with biophysical experiments

Pepsin-like aspartic proteases (PAPs) are a class of aspartic proteases which shares tremendous structural similarity with human pepsin. One of the key structural features of PAPs is the presence of a β-hairpin motif otherwise known as flap. The biological function of the PAPs is highly dependent on the conformational dynamics of the flap region. In apo PAPs, the conformational dynamics of the fla

Postpartumblödningar med blodtransfusioner har ökat

Postpartum hemorrhage is responsible for one fourth of the maternal mortality worldwide. In high resource countries there is an increasing trend in frequency of postpartum hemorrhage and need of blood transfusions. The reason for this increase is probably multifactorial. Major bleeding requires massive blood transfusion (MT), defined as transfusion of >10 units of erythrocytes within 24 hours. In

Drought impact in the Bolivian Altiplano agriculture associated with the El Niño-Southern Oscillation using satellite imagery data

Drought is a major natural hazard in the Bolivian Altiplano that causes large agricultural losses. However, the drought effect on agriculture varies largely on a local scale due to diverse factors such as climatological and hydrological conditions, sensitivity of crop yield to water stress, and crop phenological stage among others. To improve the knowledge of drought impact on agriculture, this st

Cardiac arrest in COVID-19 : characteristics and outcomes of in- and out-of-hospital cardiac arrest. A report from the Swedish Registry for Cardiopulmonary Resuscitation

AIM: To study the characteristics and outcome among cardiac arrest cases with COVID-19 and differences between the pre-pandemic and the pandemic period in out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA). METHOD AND RESULTS: We included all patients reported to the Swedish Registry for Cardiopulmonary Resuscitation from 1 January to 20 July 2020. We defined 16 March 2020

Topological superconductivity in semiconductor-superconductor-magnetic-insulator heterostructures

Hybrid superconductor-semiconductor heterostructures are promising platforms for realizing topological superconductors and exploring Majorana bound state physics. Motivated by recent experimental progress, we theoretically study how magnetic insulators offer an alternative to the use of external magnetic fields for reaching the topological regime. We consider different setups, where (1) the magnet

Effects of TiN Top Electrode Texturing on Ferroelectricity in Hf1-xZrxO2

Ferroelectric memories based on hafnium oxide are an attractive alternative to conventional memory technologies due to their scalability and energy efficiency. However, there are still many open questions regarding the optimal material stack and processing conditions for reliable device performance. Here, we report on the impact of the sputtering process conditions of the commonly used TiN top ele

Efficacy of an ACT and Compassion-Based eHealth Program for Self-Management of Chronic Pain (iACTwithPain) : Study Protocol for a Randomized Controlled Trial

Background: Chronic pain (CP) has serious medical and social consequences and leads to economic burden that threatens the sustainability of healthcare services. Thus, optimized management of pain tools to support CP patients in adjusting to their condition and improving their quality of life is timely. Although acceptance and commitment therapy (ACT) is considered an evidence-based psychological a

Prevention of ischemic myocardial contracture through hemodynamically controlled DCD

Purpose—Ischemic myocardial contracture (IMC) or ‘‘stoneheart’’ is a condition with rapid onset following circulatory death. It inhibits transplantability of hearts donated uponcirculatory death (DCD). We investigate the effectiveness of hemodynamic normalization upon withdrawal of life-sustaining therapy (WLST) in a large-animal controlled DCD model, with the hypothesis that reduction in cardiac

Improved Urinary Cortisol Metabolome in Addison Disease : A Prospective Trial of Dual-Release Hydrocortisone

CONTEXT: Oral once-daily dual-release hydrocortisone (DR-HC) replacement therapy has demonstrated an improved metabolic profile compared to conventional 3-times-daily (TID-HC) therapy among patients with primary adrenal insufficiency. This effect might be related to a more physiological cortisol profile, but also to a modified pattern of cortisol metabolism. OBJECTIVE: This work aimed to study cor

Body Temperature and Activity Rhythms Under Different Photoperiods in High Arctic Svalbard ptarmigan (Lagopus muta hyperborea)

Organisms use circadian rhythms to anticipate and exploit daily environmental oscillations. While circadian rhythms are of clear importance for inhabitants of tropic and temperate latitudes, its role for permanent residents of the polar regions is less well understood. The high Arctic Svalbard ptarmigan shows behavioral rhythmicity in presence of light-dark cycles but is arrhythmic during the pola

Factors Associated With the Decline of C-Peptide in a Cohort of Young Children Diagnosed With Type 1 Diabetes

CONTEXT: Understanding factors involved in the rate of C-peptide decline is needed to tailor therapies for type 1 diabetes (T1D). OBJECTIVE: Evaluate factors associated with rate of C-peptide decline after a T1D diagnosis in young children. DESIGN: Observational study. SETTING: Academic centers. PARTICIPANTS: A total of 57 participants from the Environmental Determinants of Diabetes in the Young (
