Apolipoprotein E3 and E4 isoforms exhibit differing effects in countering endotoxins

Apolipoprotein E (APOE) is distributed across various human tissues and plays a crucial role in lipid metabolism. Recent investigations have uncovered an additional facet of APOE's functionality, revealing its role in host defense against bacterial infections. To assess the antibacterial attributes of APOE3 and APOE4, we conducted antibacterial assays using Pseudomonas aeruginosa and Escherichia c

Deficiency of Peptidylglycine-alpha-amidating Monooxygenase, a Cause of Sarcopenic Diabetes Mellitus

Perceived barriers and facilitators to exercise adherence in osteoarthritis : A thematic synthesis of qualitative studies

Objective: Exercise is a first-line intervention for osteoarthritis (OA). However, exercise adherence remains low, and existing studies exploring factors influencing adherence have yielded inconclusive results based on quantitative data. This study aims to synthesise qualitative studies focused on the perceived facilitators and barriers affecting exercise adherence in individuals with OA. Design:

Simultaneous shape and topology optimization on unstructured grids

In this work we present a simultaneous shape and topology optimization framework that generates large-scale 3D designs on unstructured grids. We consider a “parameter-free” shape optimization approach, wherein the nodal coordinates in the finite element mesh serve as design variables. To regularize the design changes we use a PDE-based filter, similar to the filtering techniques used in topology o

Prenatal exposure to organochlorine pesticides and polychlorinated biphenyls and risk of testicular germ cell cancer later in life

Introduction: Exposure to environmental chemicals during fetal development may increase the risk of testicular germ cell cancer (TGCC), but few studies have tested the hypothesis. We focused on organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), previously investigated in relation to other male reproductive health outcomes. Methods: We conducted a nested case-control study of 33

Modelling of anisotropic high-cycle fatigue of metals

A continuum approach for anisotropic high-cycle fatigue modelling for metals is described. The approach is based on the idea of an endurance surface moving in the stress space where the movement is described by a back-stress tensor. The movement of the endurance surface is governed by an evolution equation. Thereby, the back stress tensor memorizes the load history so that fatigue damage accumulat

Controls on the termination of the massive chert system in the Ediacaran-Cambrian Liuchapo Formation, South China

The widespread deposition of marine siliceous rocks marks a fundamental shift in the ancient ocean's biogeochemical dynamics, transitioning from Precambrian systems dominated by direct inorganic silica precipitation as the primary silicon sink to modern environments where microbial processes strongly govern silica dissolution. The massive Liuchapo chert in the Nanhua Basin, South China, formed dur

Integrated conodont biostratigraphy and stable isotope chemostratigraphy from the Tremadocian (Lower Ordovician) of the Yangtze Platform, South China

Tremadocian (Lower Ordovician) carbonate rocks were collected from the Xiangshuidong section in the Hubei Province, South China, and analysed for conodont biostratigraphy. A total of 24 species belonging to 16 genera were recovered from the Nantsinkuan and Fenhsiang formations. Three conodont zones are recognized based on this material: the Rossodus manitouensis Zone, Colaptoconus quadraplicatus–P

Direct observations of nucleation and early-stage growth of Au-catalyzed GaAs nanowires on Si(111)

Developing a reliable procedure for the growth of III-V nanowires (NW) on silicon (Si) substrates remains a significant challenge, as current methods rely on trial-and-error approaches with varying interpretations of critical process steps such as sample preparation, Au-Si alloy formation in the growth reactor, and NW alignment. Addressing these challenges is essential for enabling high-performanc

When past meets present : A mixed-methods study of heating practices in Sweden during the energy crisis

During the energy crisis in 2022/2023, households across Europe were encouraged to reduce their energy use to contribute to energy sufficiency, sovereignty, and solidarity. This paper explores energy saving heating practices among Swedish single-family households during the energy crisis in 2022. The Energy Cultures Framework is used to investigate how material culture and norms affect practices f

Practical guidance for management of atrial fibrillation in sports cardiology

IMPORTANCE: Atrial fibrillation (AF), the most prevalent sustained arrhythmia, portends higher risk of cardiovascular morbidity and mortality, and is associated with quantifiable impairment in quality of life. While physical activity is widely recognized for its cardiovascular benefits, recent evidence challenges its role in the development of AF. OBSERVATIONS: Emerging data suggest a U-shaped rel

Venous thromboembolism in children with Hodgkin lymphoma – A population-based study in Sweden, Finland, and Denmark

Background: Children and adolescents with Hodgkin lymphoma (HL) are susceptible to developing venous thromboembolism (VTE) due to several predisposing factors such as cancer itself, central venous catheter use, mediastinal mass, and glucocorticoid therapy, yet reports on the topic are scarce. Aim: To study incidence, risk factors, and treatment of VTE, and the use of thromboprophylaxis, in a retro

Variation in the pollen diet of managed bee species across European agroecosystems

Bee-mediated pollination plays a crucial role in sustaining global food production. However, while the demand for these pollination services is increasing, many bee species are in decline. To address this discrepancy, farmers use managed bee species to improve crop pollination. One key factor affecting pollination efficiency is the affinity for the crop of interest (i.e., the extent to which a bee

Individual and competitive removal of Cr(VI) and Cu(II) by microbial fuel cell constructed wetlands

Microbial fuel cell constructed wetlands (MFC-CWs) represent a novel, low-carbon wastewater treatment technology for heavy metal removal and bioelectricity generation. This study compared MFC-CW performance in treating single and mixed heavy metal wastewater. Single Cu(II) and Cr(VI) removal was more efficient individually than in combination. For Cu(II), removal efficiency initially increased wit

Apolipoprotein A-IV is induced by high-fat diets and mediates positive effects on glucose and lipid metabolism

Objective: Low-carbohydrate, high-fat diets under eucaloric conditions are associated with several health-beneficial metabolic effects in humans, particularly in the liver. We recently observed that apolipoprotein A-IV (apoA-IV), a highly abundant apolipoprotein, was among the most upregulated proteins in circulation after six weeks of consuming a high-fat diet in humans. However, the impact of di
