Measures of cortical microstructure are linked to amyloid pathology in Alzheimer's disease

Markers of downstream events are a key component of clinical trials of disease-modifying therapies for Alzheimer's disease. Morphological metrics like cortical thickness are established measures of atrophy but are not sensitive enough to detect amyloid-beta (Aβ)- related changes that occur before overt atrophy become visible. We aimed to investigate to what extent diffusion MRI can provide sensiti

MHC diversity and expression in a songbird : Temporal and transgenerational variation

The immune system is of central importance to clear-off pathogens in order to keep an organism healthy. In vertebrates, the Major Histocompatibility Complex (MHC) is a genomic region that holds key genes involved in adaptive immunity and in particular in the antigen presenting process. The presentation relies on MHC class I (MHC-I) and MHC class II (MHC-II) molecules that are encoded by MHC-I and

Participation in prospective studies of children with high risk for type 1 diabetes. Psychological effects, experience, and study compliance

AbstractAim: The overall aim of the thesis was to examine the psychosocial effects and family reactions to participation in longitudinal studies with their children at high risk for type 1 diabetes. Additionally, we aimed to develop a shorter form for the children to measure their anxiety when thinking of their risk of developing type 1 diabetes, which could be used in The Environmental Determinan

Epidemiological, mechanistic and genetic aspects of vascular ageing and arterial stiffness in the population

The core feature of vascular ageing is the age-associated stiffening of the large, elastic arteries, or arteriosclerosis. This results in a diminished volume-buffering function and is therefore central for the increase in systolic blood pressure and pulse pressure seen with advancing age. Since there are considerable individual differences regarding the rate of vascular ageing, the aim was to desc

ONSHORE WINDMILL FOUNDATIONS - Evaluation of new proposals

Windmill structures must withstand very high horizontal loading giving an extremely large overturning moment on the foundation. These structures have very low stability loads in comparison to the overturning loads. The traditional way to solve the construction problem uses a shallow foundation with a massive concrete volume or a piled foundation to resist the extreme overturning moment. This work

Exposure to maternal obesity programs sex differences in pancreatic islets of the offspring in mice

AIMS/HYPOTHESIS: Obesity during pregnancy increases offspring type 2 diabetes risk. Given that nearly half of women of child-bearing age in many populations are currently overweight/obese, it is key that we improve our understanding of the impact of the in utero/early life environment on offspring islet function. Whilst a number of experimental studies have examined the effect of maternal obesity

Effect of tailored dose-dense chemotherapy vs standard 3-weekly adjuvant chemotherapy on recurrence-free survival among women with high-risk early breast cancer : A randomized clinical trial

IMPORTANCE Standard dosing of chemotherapy based on body surface area results in marked interpatient variation in pharmacokinetics, toxic effects, and efficacy.Whether tailored dosing can improve outcomes is unknown, as is the role of dose-dense adjuvant chemotherapy. OBJECTIVE To determine whether tailored dose-dense adjuvant chemotherapy improves the outcomes of early breast cancer compared with

Worldwide trends in diabetes since 1980 : A pooled analysis of 751 population-based studies with 4.4 million participants

Background: One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are aff ecting the number of adults with d

How to think about a place not yet : Studies of affordance and site-based methods for the exploration of design professionals' expectations in urban development processes

ABSTRACTAs a part of a democratic demand for transparency in urban development processes it is important that design professionals hold the ability to scrutinise their own work process, and at certain stages let go of predefined ideas of future realities. This work revolves around how design professionals perceive options for design in such situations. A basic assumption in this work is that a des

Cardiovascular organ damage in type 2 diabetes mellitus : The role of lipids and inflammation

Background: The relationship between dyslipidemia, inflammation and CV organ damage in type 2 diabetes mellitus (T2DM) is complex. Insulin resistance and inflammatory cytokines interleukins (ILs) increase plasma triglycerides (TG). ILs also up-regulate expression of matrix-metalloproteinases (MMPs) that, together with TG, decrease high density lipoprotein cholesterol (HDL) levels. High TG, low HDL

Hyaluronan deposition in islets may precede and direct the location of islet immune-cell infiltrates

AIMS/HYPOTHESIS: Substantial deposition of the extracellular matrix component hyaluronan (HA) is characteristic of insulitis in overt type 1 diabetes. We investigated whether HA accumulation is detectable in islets early in disease pathogenesis and how this affects the development of insulitis and beta cell mass.METHODS: Pancreas tissue from 15 non-diabetic organ donors who were positive for islet

Entomological Lidar : Target Characterization and Field Applications

Sin ringa storlek till trots har insekter enorm inverkan på vårt samhälle och våra liv. Bin, som är centrala för att vårt jordbruk ska fungera, har minskat drastiskt i antal de senaste åren. En utbredd bidöd skulle i bästa fall tvinga oss lägga om vår kosthållning markant, och i värsta fall leda till svält. Utöver detta skulle växter som är beroende av bin för sin fortplantning och djur som äter bThis thesis treats entomological lidar from various angles: laboratory reference work on insects of interest, methodological development of lidar- and data processing methods, as well as field implementations of lidar techniques for entomological research. Insects are crucial components of ecosystems and are currently in a global decline. In this thesis, insects are mainly studied in their roles a

Elucidating Genetic and Biochemical Aspects of the P1 and Sda Carbohydrate Histo-Blood Group Antigens

Human histo-blood groups are inherited polymorphic variants that occur in the molecular structures on the humanred blood cell (RBC) surface. Introducing foreign RBCs into a recipient lacking an antigen may activate the humoraldefence leading to a hemolytic transfusion reaction. Antigenic differences can also cause hemolytic disease of thefetus and newborn (HDFN). Blood group antigens are implicate

Persistent organic pollutants, pre-pregnancy use of combined oral contraceptives, age, and time-to-pregnancy in the SELMA cohort

BACKGROUND: We are exposed to several chemicals such as persistent organic pollutants (POPs) in our everyday lives. Prior evidence has suggested that POPs may have adverse effects on reproductive function by disrupting hormone synthesis and metabolism. While there is age-related decline of fertility, the use of hormonal combined oral contraceptives (COCs) and its association to return of fertility

What intent, whose intent and to what extent?: The Knowledge requirement in indirect patent infringement

In Germany, the UK, the US and the Scandinavian countries there is a distinct difference between direct and indirect (also referred to as contributory) statutory patent infringement. The patent laws that regulate incursions on the exclusive rights of patent holders in these jurisdictions generally distinguish between direct patent infringement on the one hand, which is based on wholly objective cr

Helicobacter pylori screening in clinical routine during hospitalization for acute myocardial infarction

Background: Potent antithrombotic therapy has significantly improved prognosis for patients with acute myocardial infarction (AMI), however, at a price of increased bleeding risk. Chronic gastric infection with Helicobacter pylori (Hp) commonly causes upper gastrointestinal bleeding and is proposed as a risk factor for subsequent bleeding post AMI. The prevalence of active Hp in a current AMI popu

Precision Prognostics for Cardiovascular Disease in Type 2 Diabetes : A Systematic Review and Meta-analysis

BACKGROUND: Precision medicine has the potential to improve cardiovascular disease (CVD) risk prediction in individuals with type 2 diabetes (T2D).METHODS: We conducted a systematic review and meta-analysis of longitudinal studies to identify potentially novel prognostic factors that could improve CVD risk prediction in T2D. Out of 9380 studies identified, 416 studies met inclusion criteria. Outco
