Low-cost measurements of the 'resonant' wavelengths reflected by a compact disk under skimming rays

We demonstrate the construction and utilization of an affordable apparatus using readily available materials to accurately measure in a quantitative manner the wavelengths reflected by a compact disc (CD) under skimming light rays. In fact, only a limited number of wavelengths can be revealed when light rays from a white lamp are directed at a CD (or a DVD) in a manner that specifically selects th

Deep-learning image enhancement and fibre segmentation from time-resolved computed tomography of fibre-reinforced composites

Monitoring the microstructure and damage development of fibre-reinforced composites during loading is crucial to understanding their mechanical properties. Time-resolved X-ray computed tomography enables such an in-situ, non-destructive study. However, the photon flux and fibre-matrix contrast limit its achievable spatial and temporal resolution. In this paper, we push the limits of temporal and s

Incremental Value of Exercise ECG to Myocardial Perfusion Single-Photon Emission Computed Tomography for Prediction of Cardiac Events

BACKGROUND: Both myocardial perfusion single-photon emission computed tomography (MPS) and exercise ECG (Ex-ECG) carry prognostic information in patients with stable chest pain. However, it is not fully understood if combining the findings of MPS and Ex-ECG improves risk prediction. Current guidelines no longer recommend Ex-ECG for diagnostic evaluation of chronic coronary syndrome, but Ex-ECG cou

CRP, C-Peptide, and Risk of First-Time Cardiovascular Events and Mortality in Early Type 2 Diabetes : A Danish Cohort Study

We investigated the relationship between hs-CRP, a marker of low-grade inflam-mation, alone or in combination with C-peptide, a marker of hyperinsulinemia/ insulin resistance, and risk for cardiovascular events (CVEs) and mortality in patients recently diagnosed with type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS In patients with recent-onset T2D, we measured serum hs-CRP (n = 7,301) and C-pep

Sömnstörningar vanliga efter behandling för hjärntumör som barn

Hjärntumörer är en av de vanligaste barncancerdiagnoserna och många som överlever drabbas av sömnstörningar efteråt. Tumörens läge i hjärnan, tillsammans med vilken behandling man får, påverkar hur stor risken är. Det finns dock även andra faktorer som påverkar, och övervikt hos barnet är den enskilt största riskfaktorn för sömnsvårigheter.

Multilateral Climate Finance Coordination : Politics and Depoliticization in Practice

The governance of public climate finance for mitigation and adaptation in developing countries is fragmented on both the international and national levels, with a high diversity of actors with overlapping mandates, preferences, and areas of expertise. In the absence of one unifying actor or institution, coordination among actors has emerged as a response to this fragmentation. In this article, we

Molecular complexity of mammary glands development : a review of lactogenic differentiation in epithelial cells

The mammary gland is a dynamic organ with various physiological processes like cellular proliferation, differentiation, and apoptosis during the pregnancy-lactation-involution cycle. It is essential to understand the molecular changes during the lactogenic differentiation of mammary epithelial cells (MECs, the milk-synthesizing cells). The MECs are organized as luminal milk-secreting cells and bas

Management of antineutrophil cytoplasmic antibody–associated vasculitis with glomerulonephritis as proposed by the ACR 2021, EULAR 2022 and KDIGO 2021 guidelines/recommendations

Updated guidelines on the management of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) were released in 2021 by the American College of Rheumatology jointly with the Vasculitis Foundation and, subsequently, in 2022 by the European Alliance of Associations for Rheumatology. In addition, in 2021, the Kidney Disease: Improving Global Outcomes had released updated recommendatio

A concise review of glycerol derivatives for use as fuel additives

Due to renewable fuel mandates worldwide, the increase in biodiesel production has caused an oversupply of low-cost glycerol on the markets, which can negatively affect the sustainability of the biodiesel industry as a whole. In order to avoid that scenario, the transformation of glycerol into value-added products has been investigated, and the production of additives for internal combustion engin

Association Between Severe Nonadherence to Hydroxychloroquine and Systemic Lupus Erythematosus Flares, Damage, and Mortality in 660 Patients From the SLICC Inception Cohort

Objective: The goals of this study were to assess the associations of severe nonadherence to hydroxychloroquine (HCQ), objectively assessed by HCQ serum levels, and risks of systemic lupus erythematosus (SLE) flares, damage, and mortality rates over five years of follow-up. Methods: The Systemic Lupus International Collaborating Clinics (SLICC) Inception Cohort is an international multicenter init

Results of the first nationwide cohort study of outcomes in dialysis and kidney transplant patients before and after vaccination for COVID-19

Background. Patients on kidney replacement therapy (KRT) have been identified as a vulnerable group during the coronavirus disease 2019 (COVID-19) pandemic. This study reports the outcomes of COVID-19 in KRT patients in Sweden, a country where patients on KRT were prioritized early in the vaccination campaign. Methods. Patients on KRT between January 2019 and December 2021 in the Swedish Renal Reg

Surgical management of necrotising enterocolitis in Sweden : A national cohort study

Aim: Necrotising enterocolitis (NEC) is the dominating surgical emergency in preterm neonates. The aims were to investigate indications, surgical management and mortality for surgically treated neonates with NEC. Methods: Data were retrieved from the Swedish Neonatal Quality Register for Swedish neonates with surgically treated NEC from 1 January 2017 to 31 December 2021. Diagnosis was validated b
