AIMS/HYPOTHESIS: Genetic and environmental factors are believed to cause type 1 diabetes. The aim of this study was to investigate the influence of maternal BMI and gestational weight gain on the subsequent risk of childhood type 1 diabetes.METHODS: Children in the Swedish National Quality Register for Diabetes in Children were matched with control children from the Swedish Medical Birth Register.

BACKGROUND: Medical decision making has long been in focus, but little is known of the preferences and conditions for elderly people with co-morbidities to participate in medical decision making. The main objective of the present study was to investigate the preferred and the actual degree of control, i.e. the role elderly people with co-morbidities wish to assume and actually had with regard to i

Breast cancer is one of the most common cancers in women. It is most commonly treated by the surgical removal of the tumour in combination with (neo)-adjuvant therapy (hormone, chemo- or radio- therapy before or after surgery). However, a large number of patients are over treated, with approximately 60% being given adjuvant therapy when already cured by surgery alone. This causes many undesirable

Vineyards shape important economic, cultural, and ecological systems in many temperate biomes. Like other agricultural systems, they can be multifunctional landscapes that not only produce grapes, but also for example serve as wildlife habitat, sequester carbon, and are places of rich traditions. However, research and management practices often focus mostly on individual, specific ecosystem servic

The thesis comprises an analysis of the heat transfer phenomenon in solid oxide fuel cells (SOFCs) and a description of various transport phenomena in a solid oxide electrolysis cell. Both devices are encompassed under the solid oxide electrochemical cell concept. Moreover, a CFD model of an SOEC was developed to study the behavior of the cell under different conditions of operating and structural

Katedralen var en av de mest centrala institutionerna i det medeltida samhället. Kring stiftets biskop samlades den kyrkliga makten och dåtidens elit, dygnet runt firades gudstjänster och här utbildades stiftets präster. En viktig roll för livet i och kring katedralen hade domkapitlet eller katedralkapitlet, dvs det organiserade prästerskap som betjänade domkyrkan och bistod biskopen.I mitt avhandThe cathedral was one of the most important institutions in medieval Europe. The local as well as ecclesiastical elite gathered around it and its bishop; the liturgy was celebrated day and night, year after year; the cathedral served as educational institution of the clergy. The cathedral chapter, i.e. the organized clergy that served at the cathedral, played a decisive part in all this.The overar

Popular Abstract in Swedish Syn är avgörande för många djurs överlevnad. En väldigt viktig del av ögat är linsen då ljuset fokuseras genom den. I denna studie har jag undersökt hur fisklinser fokuserar ljus. Valet av fiskar som försöksdjur berodde på att de är lätta att skaffa och deras linser är klotformade, vilket underlättar beräkningen av strålgången och linsens optiska egenskaper. Hos fiskar Vision is an important source of information for many animals. The lens plays a central role in the visual pathway and hence the ecology of these animals. Fish have spherically shaped crystalline lenses that contain a gradient of refractive index. Like all refracting elements, lens performance depends on the wavelength of the refracted light. This wavelength dependent focusing leads to chromatic a

Context. Determination and calibration of the ages of stars, which heavily rely on stellar evolutionary models, are very challenging, while representing a crucial aspect in many astrophysical areas. Aims. We describe the methodologies that, taking advantage of Gaia-DR1 and the Gaia-ESO Survey data, enable the comparison of observed open star cluster sequences with stellar evolutionary models. The

Preeclampsia (PE) is an important pregnancy complication that affects 3-8% of women worldwide and is a leading cause of maternal and fetal morbidity and mortality. It is known that PE is associated with placental dysfunction, resulting in hypoxia, oxidative stress, altered metabolism and production of inflammatory cytokines. Hypoxia could enhance erythropoiesis and induce non-erythroid hemoglobin
