Plasma amine oxidase

Copper-containing amine oxidases have been found in a wide range of eukaryotic cells of fungal, plant, and mammalian origin. 1 - 3 The Cu-AOs isolated from different tissues or phylae have many properties in common, but are distinctly different enzymes with respect to molecular characteristics and substrate specificity. This chapter will examine what is known about the Cu-AO which occurs in the pl

Numerical and experimental investigation of the cecost swirl burner

Clean technology has become a key feature due to increasing environmental concerns. Swirling flows, being directly associated with combustion performance and hence minimized pollutant formation, are encountered in most propulsion and power-generation combustion devices. In this study, the development process of the conceptual swirl burner developed at the Swedish National Centre for Combustion and

Rodents, not birds, dominate predation-related ecosystem services and disservices in vertebrate communities of agricultural landscapes

To understand the relationship between conservation measures and agricultural yields, we need to know the contributions of organisms to both ecosystem services and disservices. We studied the activity and contribution of birds and mammals to intermediate ecosystem services (predation of weed seeds or invertebrate pests) and disservices (predation of crop seeds or beneficial invertebrates) in south

In situ observation of synthesized nanoparticles in ultra-dilute aerosols via X-ray scattering

In-air epitaxy of nanostructures (Aerotaxy) has recently emerged as a viable route for fast, large-scale production. In this study, we use small-angle X-ray scattering to perform direct in-flight characterizations of the first step of this process, i.e., the engineered formation of Au and Pt aerosol nanoparticles by spark generation in a flow of N2 gas. This represents a particular challenge for c

Variations in the Composition of the Phases Lead to the Differences in the Optoelectronic Properties of MAPbBr3 Thin Films and Crystals

Photoluminescence (PL) spectra from thin films (TFs) and bulk crystals (BCs) of hybrid organo-halide perovskites are significantly different, the origin of which and their impact on the efficiency of the perovskite-based photoactive devices have been debated. We have used two-photon PL to study the temperature-dependent changes in the spectra of the TFs and the BCs of methylammonium lead bromide (

Major intraoperative bleeding during pancreatoduodenectomy - preoperative biliary drainage is the only modifiable risk factor

Background: Pancreatoduodenectomy is associated with a high risk of complications. The aim was to identify preoperative risk factors for major intraoperative bleeding. Methods: Patients registered for pancreatoduodenectomy in the Swedish National Pancreatic and Periampullary Cancer Registry, 2011 to 2016, were included. Major intraoperative bleeding was defined as ≥1000 ml. Univariable and multiva

Experimental investigation of the axial strength of glued-in rods in cross laminated timber

This paper presents results from an experimental assessment of glued-in rods in cross laminated timber (CLT). For the purposes of the study more than 60 pull–pull tests were performed, where the specimens varied in terms of bonded-in length (from 80 to 400 mm), rod diameter (16–24 mm) and rod-to-grain angle (parallel and perpendicular). Several different failure modes that are not common for other

The Impact of Nonequilibrium Conditions in Lung Surfactant : Structure and Composition Gradients in Multilamellar Films

The lipid-protein mixture that covers the lung alveoli, lung surfactant, ensures mechanical robustness and controls gas transport during breathing. Lung surfactant is located at an interface between water-rich tissue and humid, but not fully saturated, air. The resulting humidity difference places the lung surfactant film out of thermodynamic equilibrium, which triggers the buildup of a water grad

Under threat : Rules-based fiscal policy and how to preserve it

Rules-based fiscal policy is under threat. Over the last two decades, it proved frustratingly complicated to strike the right balance between three essential properties of sound fiscal policy rules: simplicity, flexibility, and enforceability. Simplicity has been sacrificed to ensure that more contingent (i.e. flexible) rules remained enforceable. The resulting arrangements have failed to adequate

Trading off safety against food : state dependent habitat choice and foraging in crucian carp

The influence of hunger level and predation risk on habitat choice and foraging in crucian carp, Carassius carassius, were studied in a laboratory experiment. Experiments were carried out in aquaria with or without a predator (pike, Esox lucius). Habitat use and foraging activity of three-fish foraging groups of either fed or hungry crucian carp were studied. Fish were allowed to choose between an

Validation of Catquest-9SF in Danish : developing a revised form of the Catquest-9SF – the Danish Catquest-7SF

Purpose: The primary goal was to validate a Danish translated version of the Catquest-9SF by Rasch analysis. The secondary goal was to investigate whether preoperative Catquest-9SF scores, best-corrected visual acuity, comorbidity, gender, age or corneal astigmatism could predict improvements in subjective outcome. Methods: In a prospective trial, 250 patients eligible for cataract surgery were in

Neuropeptide Y treatment induces retinal vasoconstriction and causes functional and histological retinal damage in a porcine ischaemia model

Purpose: To investigate the effects of intravitreal neuropeptide Y (NPY) treatment following acute retinal ischaemia in an in vivo porcine model. In addition, we evaluated the vasoconstrictive potential of NPY on porcine retinal arteries ex vivo. Methods: Twelve pigs underwent induced retinal ischaemia by elevated intraocular pressure clamping the ocular perfusion pressure at 5 mmHg for 2 hr follo

Secular trends in work disability and its relationship to musculoskeletal pain and mental health : A time-trend analysis using five cross-sectional surveys (2002-2010) in the general population

Objectives: International evidence suggests that rates of inability to work because of illness can change over time. We hypothesised that one reason for this is that the link between inability to work and common illnesses, such as musculoskeletal pain and mental illness, may also change over time. We have investigated this in a study based in one UK district. Methods: Five population surveys (span
