The Swedish version of the PACU-Behavioural Pain Rating Scale: a reliable method of assessing postoperative pain?

One of the obstacles to effective pain management in the Post-Anaesthesia Care Unit (PACU) is the lack of systematic and comprehensive methods for assessing and treating postoperative pain. Nurses' intuitive knowledge of pain were verbalized and divided into four categories of pain behaviours in the PACU-Behavioural Pain Rating Scale. The aim of the present study was to test the reliability of the

Mechanistic Studies of Dinuclear Metalloenzymes - A Model Approach

Popular Abstract in Swedish Enzymer är viktiga ämnen i naturen. Vi talar då och då om att vi förbränner vår mat. Trots detta känner vi oss oftast inte särskilt varma, i alla fall inte så att det bränns. Visst bränner vi vår mat. Socker omvandlas till koldioxid och vatten precis som om vi hade eldat upp det utanför kroppen. Skillnanden är att kroppen omvandlar sockret långsammare och mer kontrollerWith the goal to study the mechanisms of dinuclear metalloenzymes, a new line of synthetic and computational models were prepared and studied. Mixed imidazole and carboxylate multidentate complexes were synthesized to better simulate carboxylate-rich ligand environments. Of the compounds, which showed to be the most useful, were one symmetric and the other one asymmetric and in both cases they wer

Determination of Persistent Organic Pollutants in Solid Environmental Samples Using Accelerated Solvent Extraction and Supercritical Fluid Extraction. Exhaustive extraction and sorption/desorption studies of PCBs.

Human activity is constantly causing environmental problems due to production and release of numerous chemicals. A group of compounds of special concern is persistent organic pollutants (POP). These toxic, lipophilic chemicals have a high chemical and biological stability, and tend to accumulate in the lipid phase of living organisms. A major sink for POPs are sediments, and consequently these are

Hand Veins Feature Extraction using DT-CNNs

As the identification process is based on the unique patterns of the users, biometrics technologies are expected to provide highly secure authentication systems. The existing systems using fingerprints or retina patterns are, however, very vulnerable. One’s fingerprints are accessible as soon as the person touches a surface, while a high resolution camera easily captures the retina pattern. Thus,

Analysis of the state and size of silver on alumina in effective removal of NOx from oxygen rich exhaust gas

Ag/alumina catalysts with different silver contents for octane-SCR were prepared by impregnation and incipient wetness methods. Activity tests revealed that the decisive factor for high activity is not only a high dispersion of silver, but also the ability of the system to redisperse clustered silver. Determination of dispersion by TEM/HAADF and O-2-chemisorption experiments resulted in values clo

From change blindness to choice blindness

The phenomenon of change blindness has received a great deal of attention during the last decade, but very few experiments have examined the effects of the subjective importance of the visual stimuli under study. We have addressed this question in a series of studies by introducing choice as a critical variable in change detection (see Johansson, Hall, Sikstrom, & Olsson, 2005, Johansson, Hall

Engineered multidomain cysteine protease inhibitors yield resistance against western flower thrips (Franklinielia occidentalis) in greenhouse trials

Western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripiclae), cause very large economic damage on a variety of field and greenhouse crops. In this study, plant resistance against thrips was introduced into transgenic potato plants through the expression of novel, custom-made, multiclomain protease inhibitors. Representative classes of inhibitors of cysteine and aspartic

Filamentous Chloroflexi are abundant in wastewater treatment processes with biological nutrient removal

Most filamentous bacteria in biological nutrient removal (BNR) processes have not been identified beyond their morphotype and simple staining reactions. Furthermore, the majority of sludge filaments observed under the microscope do not hybridize to commonly used phylogenetic probes for well characterized bacterial phyla such as the Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes. Spec

High Prevalence of Gestational Diabetes Mellitus in Rural Tanzania-Diagnosis Mainly Based on Fasting Blood Glucose from Oral Glucose Tolerance Test

Gestational diabetes mellitus (GDM) is associated with poor pregnancy outcomes and increased long-term risk of metabolic diseases for both mother and child. In Tanzania, GDM prevalence increased from 0% in 1991 to 19.5% in 2016. Anaemia has been proposed to precipitate the pathogenesis of GDM. We aimed to examine the prevalence of GDM in a rural area of Tanzania with a high prevalence of anaemia a

Systemic phenotype related to primary Sjögren's syndrome in 279 patients carrying isolated anti-La/SSB antibodies

OBJECTIVES: To evaluate the systemic phenotype associated with the presence of isolated anti-La/SSB antibodies in a large international registry of patients with primary Sjögren's syndrome (pSS) fulfilling the 2002 classification criteria.METHODS: The Big Data Sjögren Project Consortium is an international, multicentre registry created in 2014. Baseline clinical information from leading centres on

Quantification and detection of genetic risk factors in the familial aggregation of cancer : Habilitation thesis

SummaryCancer is a multifactorial inheritance disorder caused by a combination of small variations in genes, often acting together with environmental factors. GWASs provide a potential method to investigate the genetic basis of such complex diseases, but they are limited to two main classes of cancer susceptibility variants with different levels of risk and prevalence in the general population: ra

Gelatine-embedded electrodes-a novel biocompatible vehicle allowing implantation of highly flexible microelectrodes.

Chronic neural interfaces that are both structurally and functionally stable inside the brain over years or decades hold great promise to become an invaluable clinical tool in the near future. A key flaw in the current electrode interfaces is that their recording capabilities deteriorate over time, possibly due to the lack of flexibility, which causes movements in relation to the neural tissue tha

Efficient Compression and Rasterization Algorithms for Graphics Hardware

Despite rapid development, modern graphics hardware is still much too slow to render photo-realistic images in real time, and it will most likely remain so if we rely only on yearly growth in hardware performance. Therefore, better algorithms are constantly needed in order to advance the field. In the first part of this thesis, we present new algorithms for hardware rasterization. We investigate

Lipases as Biocatalysts in Organic Media. Influence of Enzyme Preparation and Reaction Conditions on Activity and Selectivity

The discovery that enzymes can function in organic solvents has broadened the scope of biocatalysis, making enzymes highly useful tools for organic chemists. The widespread use of enzymes as catalysts in organic solvents has, however, been limited by the low activity obtained for enzymes in organic solvents compared to aqueous solutions. The increasing demand for optically pure enantiomers in phar

Energy - and CO2 Intensities during the 19th and 20th Centuries: Sweden versus Spain

We examine energy and CO2 intensities (energy use / GDP and CO2 emissions / GDP) in Sweden and Spain during the last two hundred years. The first aim is to establish reliable and comparable time-series. We include all energy that involves some human effort in its capture. Therefore, not only do we include modern energy carriers such as coal, oil, and electricity, but also we aim to account for fir

Nanowires and Neural interfaces. Biocompatibility in the brain

Chronic neural interfaces that are able to record or stimulate neurons in the CNS are valuable instruments in use today and they hold great promise for the future both within neuroscience research and in the clinic. However, a major obstacle is that they show a decline in performance over time. Many different approaches to improve the interface designs are gradually evaluated in hope of overcoming

k.p theory of freestanding narrow band gap semiconductor nanowires

We report on a theoretical study of the electronic structures of freestanding nanowires made from narrow band gap semiconductors GaSb, InSb and InAs. The nanowires are described by the eight-band k.p Hamiltonians and the band structures are computed by means of the finite element method in a mixture basis consisting of linear triangular elements inside the nanowires and constrained Hermite triangu
