Pulmonary function and atherosclerosis in the general population : causal associations and clinical implications

Reduced lung function is associated with cardiovascular mortality, but the relationships with atherosclerosis are unclear. The population-based Swedish CArdioPulmonary BioImage study measured lung function, emphysema, coronary CT angiography, coronary calcium, carotid plaques and ankle-brachial index in 29,593 men and women aged 50–64 years. The results were confirmed using 2-sample Mendelian rand

Micro- and nanostructure specific X-ray tomography reveals less matrix formation and altered collagen organization following reduced loading during Achilles tendon healing

Recovery of the collagen structure following Achilles tendon rupture is poor, resulting in a high risk for re-ruptures. The loading environment during healing affects the mechanical properties of the tendon, but the relation between loading regime and healing outcome remains unclear. This is partially due to our limited understanding regarding the effects of loading on the micro- and nanostructure

In this article, we identify potentials, problems, and challenges related to research on aging and health, and identify and illustrate research priorities using an evolving research program as an example. Involving user representatives in the development phase, the UserAge program engages researchers at fou

Risks of non-ovarian cancers in women with borderline ovarian tumor : a national cohort study in Sweden

Background: Associations between different cancer types are known. The affirmation of the risk for non-ovarian cancer after ovarian borderline tumors (BOT) is, however, sparse. Aim: To analyze the risk of subsequent or simultaneous cancers in women with BOTs compared with the general female Swedish population. Methods: An open cohort study (1995–2018) was conducted where a diagnosis of BOTs as wel

On the interactions between RNA and titrateable lipid layers : implications for RNA delivery with lipid nanoparticles

Characterising the interaction between cationic ionisable lipids (CIL) and nucleic acids (NAs) is key to understanding the process of RNA lipid nanoparticle (LNP) formation and release of NAs from LNPs. Here, we have used different surface techniques to reveal the effect of pH and NA type on the interaction with a model system of DOPC and the CIL DLin-MC3-DMA (MC3). At only 5% MC3, differences in

Ligand-centered to metal-centered activation of a Rh(iii) photosensitizer revealed by ab initio molecular dynamics simulations

Excited state evolution of the rhodium(iii) complex [Rh(iii)(phen)2(NH3)2]2+ (phen = 1,10-phenanthroline) has been investigated theoretically to gain a better understanding of light-driven activation of high-energy metal centered states. Ab initio molecular dynamics (AIMD) simulations show the significance of asymmetric motion on a multidimensional potential energy landscape around the metal cente

Early screening outcomes before, during, and after a randomized controlled trial with digital breast tomosynthesis

Purpose: To describe and compare early screening outcomes before, during and after a randomized controlled trial with digital breast tomosynthesis (DBT) including synthetic 2D mammography versus standard digital mammography (DM) (To-Be 1) and a follow-up cohort study using DBT (To-Be 2). Methods: Retrospective results of 125,020 screening examinations from four consecutive screening rounds perform

A self-managed exercise therapy program for wrist osteoarthritis : study protocol for a randomized controlled trial

Background: Post-traumatic wrist osteoarthritis (OA) can eventually lead to pain, muscular weakness, and stiffness of the wrist, which can affect the function of the entire upper limb and reduce the quality of life. Although there is strong evidence that all patients with OA should be offered adequate education and exercises as a first-line treatment, an effective self-management program, includin

The Parliamentary Origins of Party Strength in Western Europe before the Second World War

This article uses new quantitative data to systematically test established arguments concerning the origins of party strength in 11 West European countries between 1870 and 1939. Through time-series cross-sectional analyses and using a wide range of sources, I investigate the role of the development of parliamentarism, suffrage extension, civil society, and the adoption of proportional representat

Direct band gap white light emission from charge carrier diffusion induced nanowire light-emitting diodes

Light-emitting diodes (LEDs) have been investigated during the past decades, for which a major challenge is total internal reflection that limits the light extraction efficiency. ‘Nanotree’ LEDs elegantly solve this bottleneck. Lower band gap nanowire branches are grown on higher band gap core wires. Charge carriers diffuse into the branches and recombine there. Total internal reflection is impede

Characterization of n-doped branches in nanotree LEDs

We present processed light emitting diodes (LED) devices based on GaInP core-branch nanowire (NW) structures. The LEDs rely on the charge carrier diffusion induced light emitting diode concept. The GaInP core has a higher Ga content than the branches to induce diffusion of carriers from the cores into the branches. The branches play the role of the active region in the structure, where charge carr

High-Performance and Environmentally-Friendly Bulk-Wave-Acoustofluidic Devices Driven by Lead-Free Piezoelectric Materials

Bulk-wave-acoustofluidic devices provide strong acoustic fields and high device efficiency, thereby offering high-throughput capability when processing biological samples. Such devices are typically driven by lead zirconate titanate (PZT) transducers, which contain a high content of lead, inevitably resulting in environmental and biocompatibility issues. Replacing PZT with lead-free piezoelectric

Dissecting Dopaminergic Neuron Specification at Single Cell Resolution - Insights from 3D brain organoids and xenograft models

Midbrain dopaminergic neurons exhibit a wide diversity in their projection patterns, disease vulnerability, and functions, playing key roles in voluntary motor control, cognition, and reward processing. Parkinson’s Disease, one of the most common neurodegenerative disorders, is characterized by the selective degeneration of the A9 dopaminergic neuron subtype, leading to severe motor dysfunction. D

Monoclinic distortion and magnetic transitions in FeO under pressure and temperature

Fe1-xO, although chemically simple, possesses a complex structural and magnetic phase diagram. The crystal structures of Fe1-xO and its magnetic properties at extreme conditions are still a matter of debate. Here, we performed a systematic investigation on Fe0.94O up to 94 GPa and 1700 K using synchrotron X-ray diffraction and synchrotron Mössbauer source spectroscopy. We observe a transition of F

Effect of broccoli sprout extract and baseline gut microbiota on fasting blood glucose in prediabetes : a randomized, placebo-controlled trial

More effective treatments are needed for impaired fasting glucose or glucose intolerance, known as prediabetes. Sulforaphane is an isothiocyanate that reduces hepatic gluconeogenesis in individuals with type 2 diabetes and is well tolerated when provided as a broccoli sprout extract (BSE). Here we report a randomized, double-blind, placebo-controlled trial in which drug-naive individuals with pred

Aluminum droplet combustion studies using spatiotemporal diagnostics

Aluminum is a promising carbon-free energy carrier. The combustion of aluminum in steam offers a novel method for the simultaneous production of hydrogen and heat through the reaction: 2Al + 3H2O = Al2O3 + 3H2 + heat. A comprehensive understanding of the combustion mechanism is crucial for predicting and optimizing the performance of aluminum-fueled devices.This thesis develops different lab-scale
