Objectives & Methods: Diseases of the human urinary tract represent common morbidities characterized by a high prevalence in the population of most westernized countries. The existeince of a significant number of affected patients and the recent increase in scientific attention has resulted in various experimental and clinical efforts in order to evaluate the mechanisms controlling the functio
Thylakoids isolated from tobacco were fragmented by sonication and the vesicles so obtained were separated by partitioning in aqueous polymer two-phase systems. By this procedure, grana vesicles were separated from stroma exposed membrane vesicles. The latter vesicles could be further fractionated by countercurrent distribution, with dextran-polyethylene glycol phase systems, and divided into two
Popular Abstract in Swedish I avhandlingen presenteras delar till radiomottagare med extremt låg effektförbrukning. Detta behövs då dagens samhälle blir allt mer och mer uppkopplat, och detta gäller inte bara persondatorer och mobiltelefoner. Med den snabba teknikutvecklingen inom radiokommunikation, driven av små och smarta mobiltelefoner, går det nu även att få prylar av alla de slag att tala me
Popular Abstract in Swedish Inflammationsreaktioner kan utlösas i alla vävnader som ett generellt svar på olika stimuli. En defekt eller utebliven reaktion kan leda till svåra infektion sjukdomar. De olika stimuli som startar den inflammatoriska processen frisätter olika inflammationsmediatorer i vävnaden. Dessa kan vara lagrade i celler och frisätts till omgivningen. Vad gäller arachidonsyra prod
The persistence of a low productive peasant sector in sub-Saharan Africa is one of the enigmas of development research. This study approaches the question from a historical perspective by analysing the paths of agrarian change in two contrasting cases in Malawi from the mid-1930s to the late 1970s. The cases - Thyolo and Mzimba districts - with their overt differences in terms of population densit
The Soviet era had come to an end and by 2002 a new idea of Europe was emerging which would see the enlargement of the European Union. The period called ‘transition’ was relegated to history. It denoted the transition of the Baltic and Central European states from the Warsaw Pact and the Soviet bloc to NATO and the European Union. Originally, transition was a concept used only to denote that the f
BackgroundFertility is impaired in many survivors of childhood cancer following treatment. Preservation of fertility after cancer has become a central survivorship concern. Nevertheless, several doctors, patients, and families do not discuss fertility and recommendations for fertility preservation in pediatrics are still lacking. Recommendations based on scientific evidence are needed and before t
Many full-time welders experience some sort of respiratory disorder e.g., asthma, bronchitis and metal fume fever. Thus, welding aerosols are thought to cause airway inflammation. There is a need for markers of welding aerosols in exposure assessments, and as most welding aerosols contain manganese and iron, these metals may possibly be used as an indicator. We have previously developed a novel no
Kamchatka is one of the world's most active volcanic regions and has hosted many explosive eruptions during the Holocene. These eruptions had the potential to disperse tephra over wide areas, forming time-synchronous markers wherever those tephras are found. Recent research in Kamchatka has begun to focus on the geochemical analysis of individual glass shards in order to characterise tephra layers
