Epigenetics and Obesity

Obesity is a complex and chronic disease affecting hundreds of millions of people worldwide and has reached epidemic proportions. It is important to understand the underlying mechanisms to tackle this devastating disease, thus preventing its comorbidities. The epigenome, including DNA methylation and histone modifications, appears to be the link between genetics and nongenetic factors, modulating

LES Modeling of the DLR Generic Single-Cup Spray Combustor : Validation and the Impact of Combustion Chemistry

Turbulent spray combustion in a generic kerosene-fueled single-cup combustor at typical idle and cruise conditions of an aeroengine are studied with Large Eddy Simulations (LES) using Lagrangian spray and finite-rate chemistry combustion modeling. Three reaction mechanisms of varying complexity are used to model the combustion chemistry. The choice of turbulence-chemistry interaction model is show

Effect of natural convection on charging of phase change materials in graded metal foam : Pore-scale simulation

Open-cell metal foams (MFs) possess exceptional thermal conductivity and are often utilized to enhance the phase transition efficiency of phase change materials (PCMs) that have insufficient thermal conductivity. The movement of energy within MFs during phase transition is influenced by natural convection and heat conduction. In this study, pore-scale numerical simulation (PNS) was employed to stu

The α-synuclein PET tracer [18F] ACI-12589 distinguishes multiple system atrophy from other neurodegenerative diseases

A positron emission tomography (PET) tracer detecting α-synuclein pathology will improve the diagnosis, and ultimately the treatment of α-synuclein-related diseases. Here we show that the PET ligand, [18F]ACI-12589, displays good in vitro affinity and specificity for pathological α-synuclein in tissues from patients with different α-synuclein-related disorders including Parkinson’s disease (PD) an

Design, structure and plasma binding of ancestral β-CoV scaffold antigens

We report the application of ancestral sequence reconstruction on coronavirus spike protein, resulting in stable and highly soluble ancestral scaffold antigens (AnSAs). The AnSAs interact with plasma of patients recovered from COVID-19 but do not bind to the human angiotensin-converting enzyme 2 (ACE2) receptor. Cryo-EM analysis of the AnSAs yield high resolution structures (2.6–2.8 Å) indicating

Uncovering the Electronic State Interplay at Metal Oxide Electron Transport Layer/Nonfullerene Acceptor Interfaces in Stable Organic Photovoltaic Devices

The implementation of sputter-deposited TiOx as an electron transport layer in nonfullerene acceptor-based organic photovoltaics has been shown to significantly increase the long-term stability of devices compared to conventional solution-processed ZnO due to a decreased photocatalytic activity of the sputtered TiOx. In this work, we utilize synchrotron-based photoemission and absorption spectrosc

Global, regional, and national burden of other musculoskeletal disorders, 1990-2020, and projections to 2050 : a systematic analysis of the Global Burden of Disease Study 2021

BACKGROUND: Musculoskeletal disorders include more than 150 different conditions affecting joints, muscles, bones, ligaments, tendons, and the spine. To capture all health loss from death and disability due to musculoskeletal disorders, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) includes a residual musculoskeletal category for conditions other than osteoarthritis, rheuma

Adjustment of Deductions in case of the Abandonment of an Investment Project : Some Remarks in Light of the Judgments of the CJEU in ITH Comercial Timișoara (C-734/19), Skellefteå Industrihus (Case C-248/20) and Vittamed Technologijos (C-293/21)

Articles 184 and 185 of the VAT Directive provide for the general obligation to adjust an initial deduction if it is higher or lower than that to which the taxable person was entitled. Does the abandonment of an investment project always imply the obligation to adjust deductions in respect of the acquired goods and/or services that cannot be used in the taxed activity of the taxable person? What i

Occupational performance problems in people with depression and anxiety

Background: Depression and anxiety often reduce people’s ability to cope with everyday occupations. There is a lack of knowledge about such problems in people of working age with depression and anxiety. Aim: To describe which problems people with depression or anxiety disorders experience when performing everyday occupations and which occupations are affected. Materials and methods: Data based on

Dietary amino acids and risk of stroke subtypes : a prospective analysis of 356,000 participants in seven European countries

Purpose: Previously reported associations of protein-rich foods with stroke subtypes have prompted interest in the assessment of individual amino acids. We examined the associations of dietary amino acids with risks of ischaemic and haemorrhagic stroke in the EPIC study. Methods: We analysed data from 356,142 participants from seven European countries. Dietary intakes of 19 individual amino acids

Pharmacological and mechanical properties of isolated pig coronary veins

Recent successful cardiac transplantation from pig to non-human primates and the first pig-to-human transplantation has put the focus on the properties of the pig heart. In contrast to the coronary arteries, the coronary veins are less well characterized and the aim was to examine the mechanical and pharmacological properties of coronary veins in comparison to the arteries. Vessel segments from th

General dental practitioners' fees for root canal treatment, coronal restoration and follow-on treatment in the adult population in Sweden : A 10-year follow-up of data from the Swedish Dental Register

Objectives: To analyze the accumulated fees connected with root filling, permanent coronal restoration and follow-on treatment charged by Swedish dentists over a 10–11-year follow-up period. Furthermore, analyzing these fees with reference to the type of restoration, tooth group, and the root-filled teeth which survived compared to those requiring extraction. Material and Methods: In 2009, the dat

A mm-Wave Differential-to-Quadrature Frequency Tripler with Automatic Locking and Quadrature Correction

This paper presents an injection-locked frequency tripler for 28-GHz direct-conversion transceivers, which takes a differential input and outputs a quadrature signal. A feedback system is added to ensure that lock occurs and to keep the quadrature error below 1° across operating frequencies and process corners. Simulations show that the tripler can cover the entire 24-30 GHz band across all corner

Red cell distribution width and its polygenic score in relation to mortality and cardiometabolic outcomes

Introduction: Elevated red cell distribution width (RDW) has been associated with a range of health outcomes. This study aims to examine prognostic and etiological roles of RDW levels, both phenotypic and genetic predisposition, in predicting cardiovascular outcomes, diabetes, chronic kidney disease (CKD) and mortality. Methods: We studied 27,141 middle-aged adults from the Malmö Diet and Cancer s

Light elements Na and Al in 58 bulge spheroid stars from APOGEE

We identified a sample of 58 candidate stars with metallicity [Fe/H]-0.8 that likely belong to the old bulge spheroid stellar population, and analyse their Na and Al abundances from Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectra. In a previous work, we inspected APOGEE-Stellar Parameter and Chemical Abundance Pipeline abundances of C, N, O, Mg, Al, Ca, Si, and Ce in this s

Association between low selenoprotein P concentrations and anaemia in hospitalized heart failure patients

AIMS: Heart failure (HF) patients with anaemia tend to have a worse outcome, with increased hospitalization rates, decreased exercise tolerance, and higher mortality compared to those without anaemia. Limited research exists on the association between selenium deficiency and anaemia specifically in HF patients, despite previous findings of a correlation in different populations. The BIOSTAT-CHF st

Investigating the amplitude and rotation of the phase spiral in the Milky Way outer disc

Context. With data releases from the astrometric space mission Gaia, exploration of the structure of the Milky Way is now possible in unprecedented detail, and has unveiled many previously unknown structures in the Galactic disc and halo. One such feature is the Gaia phase spiral where the stars in the Galactic disc form a spiral density pattern in the Z- VZ plane. Many questions regarding the pha
