Neuroendocrine abnormalities are common in Parkinson's disease (PD) and include disruption of melatonin secretion, disturbances of glucose, insulin resistance and bone metabolism, and body weight changes. They have been associated with multiple non-motor symptoms in PD and have important clinical consequences, including therapeutics. Some of the underlying mechanisms have been implicated in the pa
Buildings are one of the largest consumers of energy and materials, and hence they are also one of the largest contributors to negative environmental impacts. Traditionally, energy consumed by buildings during their operation phase was the most significant in their lifecycles and far exceeded the embodied energy. However, in contemporary low-energy buildings, the embodied energy is proportionally
The electronic spectrum of the blue copper protein plastocyanin has been studied by ab initio multiconfigurational second-order perturbation theory (the CASPT2 method). The six lowest electronic transitions have been calculated and assigned with an error of less than 2000 cm-1. The singly occupied orbital in the ground state is Cu 3d-S(Cys) 3pπ antibonding with some N(His) 2pσ character. The brigh
INTRODUCTION: Differences in treatment and outcome have been reported for persons with haemophilia (PWH) on intermediate-dose (Dutch) and high-dose (Swedish) prophylaxis, but the potential influence of sports participation has not been considered.AIM: To compare sports participation and clinical outcome between adult Dutch and Swedish PWH.METHODS: Self-reported sports participation (type and frequ

Background and purpose — Pooling data of studies evaluating total knee arthroplasty migration using radiostereometric analysis (RSA) may be compromised when the RSA method used would influence estimated differences between groups. We therefore reanalyzed a marker-based RSA study with model-based RSA to assess possible limitations of each RSA method, including insert micromotions in modular TKA and
Subband adaptive filters have been proposed to avoid the drawbacks of slow convergence and high computational complexity associated with time domain adaptive filters for acoustic echo cancellation. Subband processing introduces transmission delays caused by the filter bank and signal degradations due to aliasing effects. One efficient way to reduce the aliasing effects is to allow a higher sample
The aim of the thesis is to improve the initial steps of xylose metabolism in recombinant Saccharomyces cerevisiae. S. cerevisiae takes up xylose of poor affinity by means of hexose transporters. Metabolic control analysis was used to investigate whether the low xylose utilisation rate is due to inefficient transport. Xylose transport was found to have little control over the aerobi
