Health effects related to exposure of static magnetic fields and acoustic noise—comparison between MR and CT radiographers

Objectives: We explored the prevalence of health complaints subjectively associated with static magnetic field (SMF) and acoustic noise exposure among MR radiographers in Sweden, using CT radiographers as a control group. Additionally, we explored radiographers’ use of strategies to mitigate adverse health effects. Methods: A cross-sectional survey was sent to all hospitals with MR units in Sweden

Distinct contributions of metabolic dysfunction and genetic risk factors in the pathogenesis of non-alcoholic fatty liver disease

Background & Aims: There is substantial inter-individual variability in the risk of non-alcoholic fatty liver disease (NAFLD). Part of which is explained by insulin resistance (IR) (‘MetComp’) and part by common modifiers of genetic risk (‘GenComp’). We examined how IR on the one hand and genetic risk on the other contribute to the pathogenesis of NAFLD. Methods: We studied 846 individuals: 49

A review of green solvent extraction techniques and their use in antibiotic residue analysis

Antibiotic residues are being continuously recognized in the aquatic environment and in food. Though the concentration of antibiotic residues is typically low, adverse effects on the environment and human health have been observed. Hence, an efficient method to determine numerous antibiotic residues should be simple, inexpensive, selective, with high throughput and with low detection limits. Liqui

Testing the personality differentiation by intelligence hypothesis in a representative sample of Swedish hexagenerians

The Personality Differentiation by Intelligence Hypothesis (PDIH) predicts larger trait-variances, and smaller across-trait covariances for individuals with higher intelligence. We tested these predictions using multiple-group confirmatory factor analyses (MG-CFA), while controlling for the potential confound of systematic method variance related to reversed items using a correlated trait, correla

Internet-delivered approach-avoidance conflict task shows temporal stability and relation to trait anxiety

Excessive avoidance causes functional impairment and maintains anxiety disorders. In the laboratory, approach-avoidance conflict tasks (AACT) can be used to study approach-avoidance behavior in mixed outcome situations (i.e., the same behavior entails both aversive and rewarding consequences). We tested the feasibility of a novel, internet-delivered AACT (iAACT) by conceptually replicating results

In situ tempering of martensite during laser powder bed fusion of Fe-0.45C steel

During laser powder bed fusion (L-PBF), materials experience cyclic re-heating as new layers are deposited, inducing an in situ tempering effect. In this study, the effect of this phenomenon on the tempering of martensite during L-PBF was examined for Fe-0.45C steel. Detailed scanning electron microscopy, transmission electron microscopy, atom probe tomography, and hardness measurements indicated

Laser Doppler flowmetry evaluation of skin microvascular endothelial function in patients with metabolic syndrome

Background: Metabolic syndrome (MetS) is associated with high cardiovascular morbidity and mortality, and endothelial dysfunction is an early pathogenetic event in the MetS. Lifestyle changes and pharmacological intervention might partly restore endothelial function in MetS. Whereas an optimal non-invasive test for endothelial dysfunction is still being sought, the aim of this study was to assess

2-loop short-distance constraints for the g − 2 HLbL

The recent experimental measurement of the muon g−2 at Fermilab National Laboratory, at a 4.2σ tension with the Standard Model prediction, highlights the need for further improvements on the theoretical uncertainties associated to the hadronic sector. In the framework of the operator product expansion in the presence of a background feld, the short-distance behaviour of the hadronic light-by-light

Decision support tool to mitigate ship-induced erosion in non-uniform, sheltered coastal fairways

The negative impact of maritime traffic in terms of shore erosion in sheltered coastal fairways can be mitigated by sustainable fairway management. Mitigation measures include regulating the ship traffic in terms of speed, routes, or size of ships, but can also involve erosion protection along a fairway. For effective shoreline management of a fairway, it is essential to predict ship waves, to ide

The record of early Silurian climate changes from South China and Baltica based on integrated conodont biostratigraphy and isotope chemostratigraphy

New conodont and stable isotope data are presented from the classical Baizitian section in the Yanbian County of Sichuan Province, South China. The Telychian to Sheinwoodian strata were sampled and studied for carbon isotope stratigraphy and conodont biostratigraphy. The paired δ13Ccarb and δ13Corg data reveal a pronounced positive excursion, the Manitowoc carbon isotope excursion (Manitowoc CIE,

Water and productivity accounting using WA+ framework for sustainable water resources management : Case study of northwestern Iran

An exhaustive evaluation of water resources is a prerequisite for evidence-informed planning and implementing sustainable management strategies. However, the lack of sufficient information on water supply and consumption, alongside the technical limitations on comprehensive accounting for inter-relations and interactions between the subsystems, has resulted in decisions with often long-lasting out

Postoperative speech impairment and cranial nerve deficits after secondary surgery of posterior fossa tumours in childhood : a prospective European multicentre study

Purpose: Brain tumours constitute 25% of childhood neoplasms, and half of them are in the posterior fossa. Surgery is a fundamental component of therapy, because gross total resection is associated with a higher progression-free survival. Patients with residual tumour, progression of residual tumour or disease recurrence commonly require secondary surgery. We prospectively investigated the risk of

Comparative analysis of planted and unplanted controls for assessment of rhizosphere priming effect

The rhizosphere priming effect (RPE) is increasingly being considered to be an important regulator of soil organic matter (SOM) decomposition and nutrient turnover, with potential importance for the global CO2 budget. As a result, studies on the RPE have rapidly increased in number over the last few years. Most of these experiments have been performed using unplanted soil as the control, which cou

Inflammatory potential of the diet and association with risk of differentiated thyroid cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort

Purpose: Chronic inflammation is thought to initiate or promote differentiated thyroid cancer (DTC) and previous studies have shown that diet can modulate this inflammatory process. We aimed to evaluate the association of several dietary scores reflecting the inflammatory potential of the diet with DTC risk. Methods: Within the EPIC cohort, 450,063 participants were followed during a mean period o

Short-lived species move uphill faster under climate change

Climate change is pushing species ranges and abundances towards the poles and mountain tops. Although many studies have documented local altitudinal shifts, knowledge of general patterns at a large spatial scale, such as a whole mountain range, is scarce. From a conservation perspective, studying altitudinal shifts in wildlife is relevant because mountain regions often represent biodiversity hotsp

Managing Marine Mammals and Fisheries : A Calibrated Programming Model for the Seal-Fishery Interaction in Sweden

This paper develops a model based on the concept of Positive Mathematical Programming (PMP) that is useful for ex-ante analyses of how policy measures affect commercial fisheries. PMP models are frequently used in agriculture, but rarely for analyzing fisheries. Fisheries often face a large set of constraints such as effort regulations and catch quotas of which some might be binding and others not

Mental health, sleep and pain in elite Para athletes and the association with injury and illness ‐ a prospective study

IntroductionThe interest in Para athletes’ health continues to increase. Still, there are few studies that have evaluated health parameters beyond injury and illness in this athlete population.ObjectiveTo assess: i) the weekly proportion of elite Para athletes reporting anxiety/depression, low sleep levels (≤7 hours) and pain over 52 weeks and; ii) and to explore whether these health parameters ar
