The extracellular matrix (ECM) is a complex structural entity surrounding and supporting cells present in all tissue and organs. Cell-matrix interactions play fundamental roles during embryonic development, morphogenesis, tissue homoeostasis, wound healing, and tumourigenesis. Cell-matrix communication is kept in balance by physical contact and by transmembrane integrin receptors providing the dyn
To search for functional links between glycosylphosphatidylinositol (GPI) protein monomer-oligomer exchange and membrane dynamics and confinement, we studied urokinase plasminogen activator (uPA) receptor (uPAR), a GPI receptor involved in the regulation of cell adhesion, migration, and proliferation. Using a functionally active fluorescent protein-uPAR in live cells, we analyzed the effect that e
Expression of the membrane receptor uPAR induces profound changes in cell morphology and migration, and its expression correlates with the malignant phenotype of cancers. To identify the molecular interactions essential for uPAR function in these processes, we carried out a complete functional alanine scan of uPAR in HEK293 cells. Of the 255 mutant receptors characterized, 34 failed to induce chan
Human metapneumovirus (hMPV) is associated with respiratory tract illness especially in young children. Two hMPV genetic lineages, A and B, and four sublineages A1, A2 and B1, B2 have been defined. Infection with hMPV occurs through membrane fusion mediated by the hMPV fusion (F) protein. In this study, the inter- and intra-patient genetic diversity of the lineage A hMPV F gene was investigated. T
OBJECTIVES: To determine the prevalence of TT virus (TTV) in a population of Danish hemodialysis patients and evaluate possible relations between TTV infection and elevated levels of C-reactive protein (CRP) and hypo-response to treatment with erythropoietin (EPO).MATERIAL AND METHODS: Patients on maintenance hemodialysis at a single center were invited to participate. Demographic and clinical dat
PURPOSE: To investigate whether TT virus (TTV) viral load may be used as a surrogate marker for functional immune reconstitution in HIV-infected patients receiving highly active antiretroviral therapy (HAART).METHOD: Fifteen protease inhibitor-naïve HIV-infected patients were included in a longitudinal study. From each patient, three serum samples taken before HAART initiation and three samples ta
This study examines perceptions of humour and happiness in a world where NPM ideas have a profound influence on many aspects of everyday living.

The crustacean optic neuropiles, the lamina ganglionaris and especially the medulla externa, show a specific pattern of green fluorescence with the fluorescence histochemical method of Falck-Hillarp. Normally, only the terminals and the cell bodies fluoresce, but in reserpine-treated animals exogenous catecholamines are taken up by the whole adrenergic neuron and are thus visualized as a whole. In
It is clear that technology is a key driver of economic growth. Much less clear is where new technologies are produced and how the geography of U.S. invention has changed over the last two hundred years. Patent data report the geography, history, and technological characteristics of invention. However, those data have only recently become available in digital form and at the present time there exi
Frontotemporal dementia (FTD) and Alzheimer's disease (AD) are two frequent causes of dementia that share both clinical and neuropathological features. Common to both disorders are the neurofibrillary tangles consisting of aggregations of hyperphosphorylated tau protein. Recently, a number of different pathogenic mutations in the tau gene have been identified in families with FTD and parkinsonism
The funnel metadynamics method enables rigorous calculation of the potential of mean force along an arbitrary binding path and thereby evaluation of the absolute binding free energy. A problem of such physical paths is that the mechanism characterizing the binding process is not always obvious. In particular, it might involve reorganization of the solvent in the binding site, which is not easily c
This paper presents a method that characterizes permanent magnet synchronous traction machines connected to the drivetrain of vehicles. The method does not need additional equipment but uses the control system of the vehicle to conduct the tests. The voltage reference from the control system together with measurements of the angular frequency yield the electromagnetic characteristics of the machin
A hybrid model is used for quantification of three resilience metrics: robustness, rapidity and resilience loss. The approach is demonstrated in a case study on a municipal electricity distribution system. An overall conclusion from the case study is that the suggested method provides an overview of the resilience metrics of the electricity distribution system and that it allows the network operat
In this paper we show how to build an economically optimal feedback control strategy for the re-dispatch of electricity generation. We assume that the operator steers production in a set of controllable power plants by altering the active power set-point of each generator, within a set of predefined set-points. The operators strategy will be based on balancing the operating cost against the expect
Purpose: Wilms tumor (WT) is the most common pediatric renal tumor. Treatment planning under International Society of Paediatric Oncology (SIOP) protocols is based on staging and histologic assessment of response to preoperative chemotherapy. Despite high overall survival (OS), many relapses occur in patients without specific risk factors, and many successfully treated patients are exposed to trea
We performed an exome-wide association analysis in 1393 late-onset Alzheimer’s disease (LOAD) cases and 8141 controls from the CHARGE consortium. We found that a rare variant (P155L) in TM2D3 was enriched in Icelanders (~0.5% versus <0.05% in other European populations). In 433 LOAD cases and 3903 controls from the Icelandic AGES sub-study, P155L was associated with increased risk and earlier onse
IMPORTANCE Fluid overload occurring as a consequence of overly aggressive fluid resuscitation may adversely affect outcome in hemodynamically unstable critically ill patients. Therefore, following the initial fluid resuscitation, it is important to identify which patients will benefit from further fluid administration. OBJECTIVE To identify predictors of fluid responsiveness in hemodynamically uns
Harmonic task scheduling has many attractive properties, including a utilization bound of 100% under rate-monotonic scheduling and reduced jitter. At the same time, it places a severe constraint on the task period assignment for any application. In this paper, we explore the use of harmonic task scheduling for applications with multiple feedback control tasks. We present an algorithm for finding h
Tau positron emission tomography ligands provide the novel possibility to image tau pathology in vivo. However, little is known about how in vivo brain uptake of tau positron emission tomography ligands relates to tau aggregates observed post-mortem. We performed tau positron emission tomography imaging with 18F-AV-1451 in three patients harbouring a p.R406W mutation in the MAPT gene, encoding tau
