The constant need for higher performance and more advanced functionality has made the design and manufacturing of modern electronic chips highly demanding. Moreover, the use of smaller transistors in modern chips has increased their sensitivity to aging and faults, hence the need to constantly monitor the correct operation of these chips. To address the challenges and requirements, it has become c

Shortcomings of current techniques used for the intracerebral transplantation of ventral mesencephalic dopamine neurons include low graft survival, high variability, considerable implantation trauma and suboptimal graft integration. In order to overcome these limitations, we have adopted a microtransplantation approach which allows precise and reproducible implantation of ventral mesencephalon cel

Osteoarthritis (OA) is the most common form of arthritis and often causes pain and functional impairment. Despite its high burden on society, knowledge about the occurrence of OA and its associated mortality is sparse. The epidemiology of OA is difficult to determine due to the patients’ fluctuating symptoms and challenges in detecting and defining the radiographic disease. The specific aims of th

Efter en landreform, som genomfördes i slutet av 40- och i början av 50-talet, blev de flesta taiwanesiska bönderna hemmansägare och odlade marken på små lantegendomar. Denna efterkrigsreform banade väg för en ekonomisk utveckling som väsentligt påverkade och förändrade bondesamhället. När det taiwanesiska jordbruket visade tecken på stagnation på 1970-talet, förändrades böndernas syn på markinnehAfter post-war land reform that took place between 1949 and 1953, most Taiwanese farmers became owner-cultivators working on small landholdings. Post-war land reform paved the foundation for economic development and industrialization, processes that squeezed the agricultural sector and created changes in farming villages. When Taiwanese agriculture showed signs of stagnation in the 1970s, farmers’

With the increased availability of computational resources, the past decade has seen a rise in the use of computational fluid dynamics (CFD) for medical applications. There has been an increase in the application of CFD to attempt to predict the rupture of intracranial aneurysms, however, while many hemodynamic parameters can be obtained from these computations, to date, no consistent methodology

Background: Intravesical instillation of bacillus Calmette-Guérin (BCG) is an accepted strategy to prevent recurrence of non–muscle-invasive bladder cancer (NMIBC) but associated with significant toxicity. Objective: NIMBUS assessed whether a reduced number of standard-dose BCG instillations are noninferior to the standard number and dose in patients with high-grade NMIBC. Design, setting, and par

Background: Cardiovascular autonomic dysfunction is a multifactorial disorder manifested as orthostatic hypotension (OH) and postural orthostatic tachycardia syndrome (POTS). OH has been associated with an increased risk of cardiovascular disease (CVD), and the underlying mechanisms are not fully understood and explored.Aims and methods: Project I: We aimed to discover protein biomarkers related t

The research area of climate field reconstructions has developed strongly during the past 20 years, motivated by the need to understand the complex dynamics of the earth system in a changing climate. Climate field reconstructions aim to build a consistent gridded climate reconstruction of different variables, often from a range of climate proxies, using either statistical tools or a climate model

Popular Abstract in Swedish Hur gick det till när det svenska riket expanderade norrut och införlivade Hälsingland? Denna bok är uppställd som en generalhypotes över denna långt utdragna process, som tar sin utgångspunkt i den samhälleliga kollaps som är skönjbar under 500-talet. De inhemska maktstrukturer som gradvis byggdes upp efteråt kom under medeltidens inledande århundraden att få känna på In which way did the power structures of central Sweden expand into the territories north of the forest Ödmården during the Middle Ages? This text reads like a general hypothesis for this process, which attempts to incorporate all relevant elements in the Medieval landscape of power. The study area chosen is the province of Hälsingland. The chronological take-off is the 6th century AD, when settle

Background Immunotherapy targeting the amyloid beta (A beta) peptide is a potential strategy to slow the progression of Alzheimer's disease. We aimed to assess the safety and tolerability of CAD106, a novel active A beta immunotherapy for patients with Alzheimer's disease, designed to induce N-terminal A beta-specific antibodies without an A beta-specific T-cell response. Methods We did a phase 1,

Background The leucine-rich repeat kinase 2 gene (LRRK2) harbours highly penetrant mutations that are linked to familial parkinsonism. However, the extent of its polymorphic variability in relation to risk of Parkinson's disease (PD) has not been assessed systematically. We therefore assessed the frequency of LRRK2 exonic variants in individuals with and without PD, to investigate the role of the

This thesis investigates the adsorption, decomposition and reactions of small molecules on flat, oxidised and vicinal surfaces of late transition metals. The main technique for these studies is high resolution core level spectroscopy (HRCLS). All the studies presented in the thesis are performed in Ultra High Vacuum (UHV). The articles can be divided into three groups. The first three articles dea

The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. In this thesis chemical crosslinking and mass spectrometric mapping of crosslinked peptides has been used to investigate the
