Nanocomposites, formed by incorporating nanoparticles into a matrix of standard materials, are increasing on the market. Little focus has been directed towards safe disposal and recycling of these new materials even though the disposal has been identified as a phase of the products' life cycle with a high risk of uncontrolled emissions of nanomaterials. In this study, we investigate if the carbon
PURPOSE: Exercise during chemotherapy has beneficial long-term effects on women with breast cancer, but short-term beneficial changes have been less investigated. Though short-term changes may be important as a encouraging factor, this study aimed to investigate immediate changes in self-reported energy, stress, nausea and pain following a single exercise session during chemotherapy.METHODS: Forty
Industrially relevant, highly dispersed, Pt/ceria and reference Pt/alumina catalysts with narrow Pt particle size distributions have been prepared, characterised ex situ and studied for CO oxidation by operando infrared and X-ray absorption spectroscopy. At high CO conversions, spectator CO ad-species on ionic platinum are observed while the CO oxidation proceeds on Pt particles in a high oxidatio
Abstract When a child is hospitalized, the parents find themselves in an unfamiliar environment and their parental role changes. They are in a stressful and often anxiety-filled situation and it may be difficult for them to participate in decisions. The purpose of this study was to examine the extent to which parents participate in decisions during the course of events when their child is hospital
BACKGROUND: The COVID-19 pandemic has seen many deaths, but the majority were for causes other than COVID-19. However, end-of-life care in all settings has been affected by measures limiting the spread of the virus, for patients with and without COVID-19. The Swedish coronavirus strategy was different compared to many other countries, which might have affected end-of-life care. The aim was to desc
Structural changes in Ti1-xAlxN coated tool inserts used for turning in 316L stainless steel were investigated by XANES, EXAFS, EDS, and STEM. For coarse-grained fcc-structured Ti1-xAlxN coatings, with 0 ≤ x ≤ 0.62, the XANES spectrum changes with Al-content. XANES Ti 1s line-scans across the rake face of the worn samples reveals that TiN-enriched domains have formed during turning in Ti0.47Al0.53
To evaluate the role of polymer-surfactant interactions in drug solubilisation/stabilisation during the dissolution of spray-dried solid dispersions and their potential impact on in vivo drug solubilisation and absorption. Dissolution/precipitation tests were performed on spray-dried HPMC-Etravirine solid dispersions to demonstrate the impact of different surfactants on the in vitro performance of
The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on the world of sports due to periods of home quarantine, bans against public gatherings, travel restrictions, and a large number of postponed or canceled major sporting events. The literature hitherto is sparse, but early indications display signs of psychological impact on elite athletes due to the pandemic. However, b
The Quaternary East Asian summer rainfall evolution reconstructed with the Chinese speleothem δ18O records shows the consistency throughout the region of East Asia, and has long been considered equivalent to the monsoon intensity. Its variation and teleconnection with global climate were usually interpreted by the meridional shift of the intertropical convergence zone (ITCZ). However, many other p
Background: Radium-223, an alpha-emitting therapeutic radiopharmaceutical, prolongs overall survival (OS) in patients with symptomatic bone-predominant metastatic castration-resistant prostate cancer (mCRPC). PSMA PET/CT is a molecular imaging tool for whole-body imaging of prostate cancer and may inform on the mechanisms of radium-223 activity and treatment resistance in mCRPC patients. Methods:
Benthic fluxes of dissolved silicon (Si) from sediments into the water column are driven by the dissolution of biogenic silica (bSiO2) and terrigenous Si minerals and modulated by the precipitation of authigenic Si phases. Each of these processes has a specific effect on the isotopic composition of silicon dissolved in sediment pore fluids, such that the determination of pore fluid 30Si values can
BACKGROUND: This paper investigates the impact of a non-mandatory and age-specific social distancing recommendation on isolation behaviors and disease outcomes in Sweden during the first wave of the COVID-19 pandemic (March to July, 2020). The policy stated that people aged 70 years or older should avoid crowded places and contact with people outside the household.METHODS: We used a regression dis
AbstractPurpose: To evaluate the impact of cava balloon occlusion on the myocardium during endovascular repair of thoracic aortic pathologies.Material and methods: A prospective observational cohort study of 21 patients who underwent endovascular repair of aortic arch and thoracic aorta in a single tertiary referral center with use of inferior vena cava (IVC) balloon occlusion as a method of intra
This paper contributes to the debate on historical income inequality, and especially on the decrease in inequality found in industrialised countries during the first half of the twentieth century. We use new archival individual – and household-level data for taxpayers in Sweden’s third- largest city, Malmö, from 1900 to 1950. Previous research has established that Sweden had a distinctive downtur
The optimal FiO2 for newborn resuscitation is still not settled. We hypothesized that short-lasting oxygen ventilation after intrauterine asphyxia would not cause arterial or cerebral hyperoxia, and therefore be innocuous. The umbilical cord of fetal sheep was clamped and 10 min later, after delivery, ventilation with air (n=7) or with 100% oxygen for 3 (n=6) or 30 min (n=5), followed by air, was
We sought to assess the feasibility and estimate the benefit of sparing the neurogenic niches when irradiating the brain of pediatric patients with medulloblastoma (MB) based on clinical outcome data. Pediatric MB survivors experience a high risk of neurocognitive adverse effects, often attributed to the whole-brain irradiation that is part of standard management. Neurogenesis is very sensitive to
A possible role for infections of the pregnant mother in the development of childhood acute leukemias and lymphomas has been suggested. However, no specific infectious agent has been identified. Offspring of 74,000 mothers who had serum samples taken during pregnancy and stored in a large-scale biobank were followed up to the age of 15 years (750,000 person years) through over-generation linkages
