Popular Abstract in Swedish Läkning av achilles-senrupturer är idag en långdragen process, som ofta tar flera månader innan senan är fullt funktionsduglig. Syftet med studierna är att förbättra senläkningen i samband med achillesrupturer. Bone Morphogentic Proteins (BMP) är främst kända för att stimulera benläkning och bentillväxt. De lokala förhållandena har dock visat sig ha stor betydelse för cWe wanted to improve tendon healing by adding a growth factor. Bone Morphogenetic Proteins (BMPs) are well known to stimulate bone healing and bone formation. The local environment is of major importance for cell differentiation after a BMP has been added. Cartilage Derived Morphogenetic Proteins (CDMPs) -1, -2 and -3 (BMP 14, 13 and 12 or GDF 5, 6 and 7) form a subgroup in the BMP-family and are

During the latest years the research on the effects of moisture on clothing system has been boosted. New information has revealed phenomena, e.g. “heat pipe” effect with its condensation-evaporation cycle(s) that has not been considered earlier in prediction of physiological reactions or evaluating clothing properties. Considering the material properties, e.g. the evaporative resistance measuremen

Bacillus subtilis can grow on glycerol or glycerol-3-phosphate (G3P) as the sole carbon and energy source. The glpD gene encodes G3P dehydrogenase which is required for the catabolism of glycerol and G3P. In the non-coding leader sequence of glpD there is an inverted repeat followed by a run of AT basepairs which has been shown to function as a Rho-independent terminator (a stem-loop structure fol

Popular Abstract in Swedish Ordet polymer användes första gången av Berzelius år 1830 och kommer ursprungligen från grekiskans polymeres, vilket betyder av flera delar ("poly"=flera och "meros"=del). En polymer är en lång molekyl gjord av flera upprepande enheter. Polymerer finns i naturen (t. ex. DNA och proteiner) men kan också tillverkas genom syntetiska processer. Om polymeren innehåller laddaThe work in this thesis concerns polymer gels, especially their swelling and mechanical properties modelled using a coarse-grained model of polyelectrolytes. The method used to study polymer gels was molecular simulation utilising the simulation package MOLSIM. Particular focus is on the effect of salt, macroions and network topology effects (polydispersity, loose-ends and interpenetrating network

Supply chain management and logistics management have proven successful in the manufacturing industry, with improved productivity as a consequence. However, in the construction industry these issues have not been high on the agenda. This may be one reason why the construction industry lags behind the manufacturing industry in terms of productivity. The good thing is that there is a growing interes

Background: Airway inflammation is associated with an increased expression and release of inflammatory reactants that regulate processes of cell migration, activation and degranulation. The purpose of this study was to quantify bronchial lavage (BAL) fluid and serum levels of chemokine (IL-8), secretory leukocyte protease inhibitor (SLPI), soluble intracellular adhesion molecules-1 (sICAM-1) and s

Head-and-neck tumors are often situated at an air-tissue interface what may result in an underdosage of part of the tumor in radiotherapy treatments using megavoltage photons. especially for small fields. In addition to effects of transient electronic disequilibrium, for these small fields, an increased lateral electron range in air will result in an important extra reduction of the central axis (

Interactions between patients and physiotherapists have been studied by various researchers. Some results indicate that physiotherapists have an awareness of underlying emotions, but often respond only on an intellectual level. It seems that verbally expressed emotions may be important for interaction between physiotherapists and patients during treatment. Aim The aim of this study was to investi

The study aim was to report survival and morbidity of all patients in Sweden with peritoneal mesothelioma treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) as well as investigate whether the survival has increased on a population level since this treatment was nationalized 2011. Study data were collected from the Swedish HIPEC registry and the Swedish N

Epilepsy is a neurological disorder, affecting approximately 1% of the population. The high rate of drug-resistance in epilepsy in general (30%), and temporal lobe epilepsy (TLE) in particular, pose a serious clinical problem. Thus, novel treatments for drug-resistant epilepsy is highly warranted. Gene therapy has been suggested to be a promising approach to target drug-resistant focal epilepsy si

Health care professionals frequently describe performance management and monitoring of efficiency and quality measures for external accountability as an administrative burden with limited benefits. Professionals argue that they are subject to too tight control that signals distrust, limits professional autonomy and ultimately decreases their motivation to perform. At worst, poorly incen

This thesis examines the development of three generic pronouns in the history of the Swedish language, from the year of ca. 1225 until today. The analysis focuses on how the former noun man (‘man’), numeral en (‘one’) and personal pronoun du (‘you’) have turned into generic pronouns, thereby referring to one or a number of arbitrarily chosen human individuals. Furthermore, the study maps how the g

Once an incidental finding (IF) is discovered in the course of genomic research, the researchers are faced with the question of whether or not that finding should be reported back to the study participant. A large number of hypothetical studies and policy documents on this issue have been published, but there are very few empirical studies to inform the bioethics debate. Within a biobank research

Gasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions. Running the engine in PPC mode with high octane number fuels has the advantage of a longer premix period of fuel and air which reduces soot emissions. The problem is the ignitability at low load and idle operating conditions.In a previous study it was shown that it is possGasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions.

The time delay estimation problem associated with an ensemble of misaligned, repetitive signals is revisited. Each observed signal is assumed to be composed of an unknown, deterministic signal corrupted by Gaussian, white noise. This paper shows that maximum likelihood (ML) time delay estimation can be viewed as the maximization of an eigenvalue ratio, where the eigenvalues are obtained from the e

The connection between neuroscience, popular media and lay perceptions of the brain involves the framing of complex scientific processes and results through familiar cultural narratives and metaphors. Such narratives are often built on the premise that neuroscience, with the help of powerful new technologies, will finally solve the mysteries of brain and mind, consciousness and morality. At the sa

The withdrawal reflex system of higher vertebrates has been extensively used as a model for spinal sensorimotor integration, nociceptive processing and plasticity. In the rat, the nociceptive withdrawal reflex system appears to have a modular organization. Each reflex module controls a single muscle or a few synergistic muscles, and its cutaneous receptive field corresponds to the skin area withdr

Nanofiltration (NF) has attracted increasing attention during recent years due to the development of new applications. The advantage of NF compared with reverse osmosis (RO) and ultrafiltration (UF) is that it is possible to separate organic substances from some types of salts. It is, furthermore, also possible to separate different kinds of salts due to the negatively charged groups on the membra

Degradation of toxaphene in soil from both newly contaminated (from Sweden) and aged spills (from Nicaragua) were studied. The newly contaminated soil contained approximately 11 mg kg(-1) toxaphene while the aged Nicaraguan soil contained approximately 100 mg kg-1. Degradation was studied in anaerobic bioreactors, some of which were supplied with lactic acid and others with Triton (R) X-114. In th

Localization is an important enabling technology for many applications, such as wireless sensor networks, emergency rescue services, civil defense and transportation. Suppose that a room is equipped with several microphones (or sensors), and one person is making a sound while moving around in the room. Can one find microphone and sound source positions as well as reconstruct a room geometry? The a
