Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There are a number of legal principles regulating contract law, of which good faith (bona fides) is one. In the Nordic countries the equivalence is the principle ofloyalty. The acceptance of this principle within Swedish contract law has increased during the last two decades, but the principle has not yet been subject to codification. The scope of it has yet to be developed in order to establish its framework. The aim of this thesis is primarily to analyse the premises and conclusions of the legal justification of the principle, scientifically as well as judicially. This dissertation discusses a number of aspects ofthis principle ofloyalty. Most market transactions are connected with certain assumptions about risks. To enable cost efficient market exchange a certain amount of trust between the parties is required. The law can to a certain degree protect justified assumptions about risk by extending agreements with implied terms. In case a party breaches such a term damages may be claimed or some other sanction may be imposed. The principle can be used in the interpretation process involving contracts. It relates in particular to the determination of implied terms within contractual agreements, in order to protect the reasonable expectations of the contract parties. The principle of loyalty also obliges a party to make sure that the person and the property of the other party do not suffer any damage during the performance.

Chronic obstructive pulmonary disease (COPD) : prevalence, incidence, decline in lung function and risk factors
- 2004

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Obstructive Lung Disease in Northern Sweden (OLIN) Studies started in 1985 as an epidemiological project with the aim to detect preventable risk factors for obstructive lung diseases and allergy. In recent years there has been a focus also on obstructive sleep apnoea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) besides asthma and allergy. The aim of this thesis was to estimate the prevalence and incidence of COPD, risk factors for COPD, and decline in lung function in relation to COPD.The OLIN cohort I (cI) was recruited in 1985/86 and consisted of all 6610 subjects born 1919-20, 1934-35 and 1949-50 in eight geographical areas of Norrbotten. A postal questionnaire survey was performed in 1985/86, 1992 and in 1996. All subjects reporting respiratory symptoms at the questionnaire in 1985/86 were invited to examination in 1986, 1996 and 2002-03. A random sample of 1500 subjects from the participants at the 1996 postal questionnaire survey was invited to examination in 1996 and 2003. The participation rate has been high, ≥85%. The OLIN cohort III (cIII) was recruited in 1992, a postal questionnaire was sent to a random sample of 5681 subjects aged 20-69 years. In 1994/95 a random sample of 970 subjects were invited to examination of whom 666 participated.The prevalence of COPD in the general population sample (cIII) in ages <45 was 4.1%, 11.6%, 9.1%, and 5.1% according to the criteria of BTS1 , ERS2 , GOLD3 , and ATS4 respectively. The corresponding figures in ages ≥45 were 9.7%, 15.4%, 17.1%, and 16.5% respectively. In the age-stratified general population sample (>45 y, cI), the prevalence was 8.1% and 14.3% according to the BTS and GOLD criteria. The prevalence was strongly associated with higher age and smoking but not gender. The prevalence among smokers 76-77 years old was 45% and 50% (BTS and GOLD criteria). A majority of subjects with COPD had respiratory symptoms (in prevalent BTS 94%), most commonly cough and sputum production. Nearly a half of the subjects with COPD had contacted health care due to respiratory complaints other than common colds, but only a minority reported a physician diagnosis relevant for COPD (16% of prevalent COPD according to BTS in cIII, 31% in cI). The 10-year cumulative incidence of COPD (1986-1996) was estimated at 8.2% (BTS) and 13.5% (GOLD) in the symptomatics of cI, associated with higher age and smoking but not gender. Persistent smoking, male gender and reported chronic productive cough were associated with a faster decline in FEV1. Among incident cases of COPD a large proportion (23% of incident BTS) had a rapid decline in FEV1, >90 ml/year, corresponding to a decrease of 28 percent-units of normal value during ten years.The 7-year cumulative incidence of COPD in the random sample of cI (1996-2003) was estimated at 4.9% and 11.0% (NICE guidelines5 and GOLD) and associated with smoking but not gender. The incidence according to GOLD, but not NICE, was associated with increasing age. In multi-variate analysis most respiratory symptoms were markers of increased risk for developing COPD.In conclusion, the prevalence and the incidence of COPD were associated with age and smoking and affected by the use of different spirometric criteria. Respiratory symptoms marked an increased risk for developing COPD. A high proportion of subjects developing COPD had a rapid decline in lung function. Further, there was a substantial underdiagnosis of COPD.1 British Thoracic Society: FEV1/VC<0.70 & FEV1<80%predicted (pred), 2 European Respiratory Society: FEV1/VC<88%pred in men, <89%pred in women, 3 Global initiative for Chronic Obstructive Lung Disease:FEV1/FVC<0.70, 4 American Thoracic Society: FEV1/FVC<0.75 + symptoms or physician diagnosis, 5 The British National Institute for Clinical Excellence: FEV1/FVC<0.70 & FEV1<80%pred.

- Tetraoctadecylammonium bromide (TOAB, (CH3(CH2)17)4N+Br–) has been used to print temporary hydrophobic barriers on carboxymethylated dextran (CMD) hydrogels to create a generic platform for protein microarray applications. The primary reason for printing temporary hydrophobic barriers is to prevent cross-contamination and overflow during microdrop dispensing. Equally important is to eliminate the risk for non-specific binding to the barriers during analyte exposure. This has been accomplished by introducing a regeneration step that removes the barriers after ligand immobilization. The overall fabrication process was characterized by microscopic wetting, atomic force microscopy, imaging ellipsometry, fluorescence microscopy, surface plasmon microscopy and biospecific interaction analysis. A series of model proteins including transferrin, Protein A, anti-myoglobin and bovine serum albumin was spotted into the TOAB-defined areas under different experimental conditions, e.g. at increased humidity and reduced substrate temperature or with glycerol as an additive in the protein solution. Much emphasis was devoted to studies aiming at exploring the homogeneity and activity of the immobilized proteins. The printed barriers were removed after protein immobilization using tert-n-butyl alcohol (TBA). TBA was found to be a very efficient agent as compared to previously used salt regeneration solutions, and the regeneration time could be reduced from 30 to 10 minutes. Finally, the potential of using the well established CMD hydrogel chemistry as a platform for protein microarrays was exploited using surface plasmon microscopy.

Tidskriftsartikel (refereegranskat)abstract
- Microcontact printing (µCP) has been used to introduce temporary hydrophobic barriers on carboxymethylated dextran (CMD) hydrogels on gold. Among the investigated types of inks, tetraoctadecylammonium bromide (TOAB), electrostatically bound to the CMD layer, provided the most well-defined features both with respect to pattern-definition and reversibility upon exposure to a regeneration solution. The printed patterns were characterized by atomic force microscopy (AFM), scanning electron microscopy (SEM), microscopic wetting and imaging null ellipsometry to explore the influence of concentration of ink solution and contact time on the appearance of the printed layer. AFM revealed that the printed TOAB molecules aggregated into clusters rather than into a homogeneous mono- or multilayer on the CMD hydrogel. It was also observed that printed areas of TOAB that are larger than 25?µm are inhomogeneous most likely because of an edge transfer lithography (ETL) mechanism. A protein model system based on Protein A-rabbit antimouse Fc ? was used to evaluate the potential of the patterned surface as a protein microarray chip by means of surface plasmon microscopy (SPM). Moreover, non-specific adsorption of several proteins onto TOAB barriers was also studied using surface plasmon resonance (SPR), and it is evident that undesired adsorption can be eliminated by removing barriers after ligand immobilization, but prior to analyte exposure, by treating the patterned surface with a simple salt regeneration solution. © Springer-Verlag/Wien 2004.
