Probing the acceptor substrate binding site of Trypanosoma cruzi trans-sialidase with systematically modified substrates and glycoside libraries
Systematically modified octyl galactosides and octyl N-acetyllactosamines were assessed as inhibitors of, and substrates for, T. cruzi trans-sialidase (TcTS) in the context of exploring its acceptor substrate binding site. These studies show that TcTS, which catalyses the alpha-(2 -> 3)-sialylation of non-reducing terminal beta-galactose residues, is largely intolerant of substitution of the galac
Development of patient-centred standards of care for osteoarthritis in Europe: the eumusc.net-project.
The eumusc.net project is an initiative founded by the European Community and the European League Against Rheumatism. One aim of the project was to facilitate equal standards for musculoskeletal health across Europe. The aim of this work-package was to develop patient-centred and consensus based standards of care (SOC) for osteoarthritis (OA), which should be available in a professional and a pati
Flow structure and heat transfer in a square passage with offset mid-truncated ribs
The enhancement of heat transfer attributed from rib turbulators relative to the increased pressure drop in the channel is a crucial design parameter. Thus, the design of the truncated ribs (whose length is less than the passage width) provides options to address such cooling requirements when the pressure loss is a critical factor. Considering different types of truncated ribs, mid-truncated ribs
Dynamic glucose enhanced (DGE) MRI for combined imaging of blood-brain barrier break down and increased blood volume in brain cancer.
Recently, natural d-glucose was suggested as a potential biodegradable contrast agent. The feasibility of using d-glucose for dynamic perfusion imaging was explored to detect malignant brain tumors based on blood brain barrier breakdown.
A Unified Discussion on Signal Filtering in PID Control
The major input signals entering the PID controller are: the setpoint, the process output, and measurable load disturbances. By feeding these signals through suitable filters, the properties of the feedback loop can be improved significantly. The goal of this paper is to provide a unified discussion about these filters. The paper treats set-point handling, feedforward from load disturbances, TITO
Phytological patterns during the rise of dinosaurs in the Chinle Formation of northern New Mexico
Estimating the gravity model without gravity using panel data
This article examines the effects of zero trade on the estimation of the gravity model using both simulated and real data with a panel structure, which is different from the more conventional cross-sectional structure. We begin by showing that the usual log-linear estimation method can result in highly deceptive inference when some observations are zero. As an alternative approach, we suggest usin
47,XXY Klinefelter syndrome: Clinical characteristics and age-specific recommendations for medical management
47,XXY (Klinefelter syndrome) is the most frequent sex chromosomal disorder and affects approximately one in 660 newborn boys. The syndrome is characterized by varying degrees of cognitive, social, behavioral, and learning difficulties and in adulthood additionally primary testicular failure with small testes, hypergonadotropic hypogonadism, tall stature, and eunuchoid body proportions. The phenot
Sampling effort required to obtain repeatable average size estimates of juvenile fish
Larval and juvenile fish cohorts often have skewed size distributions due to inter-individual variation in growth rates. A resampling analysis was used to investigate how much sampling effort is required to achieve repeatable average size estimates in populations of juvenile yellowtail kingfish Seriola lalandi Valenciennes. One hundred juveniles (30 d post-hatch) were measured for total length and
Contrast-Enhanced CMR Overestimates Early Myocardial Infarct Size: Mechanistic Insights Using ECV Measurements on Day 1 and Day 7.
This study aimed to investigate whether an overestimation of infarct size on cardiac magnetic resonance (CMR) versus triphenyltetrazolium chloride (TTC) exists acutely and whether it remains after 7 days in an experimental pig model and to elucidate possible mechanisms.
Convergence of Synapses, Endosomes, and Prions in the Biology of Neurodegenerative Diseases.
Age-related misfolding and aggregation of disease-linked proteins in selective brain regions is a characteristic of neurodegenerative diseases. Although neuropathological aggregates that characterize these various diseases are found at sites other than synapses, increasing evidence supports the idea that synapses are where the pathogenesis begins. Understanding these diseases is hampered by our la
Glucocorticoid treatment and damage in the anti-neutrophil cytoplasm antibody-associated vasculitides: long-term data from the European Vasculitis Study Group trials.
Granulomatosis with polyangiitis and microscopic polyangiitis are ANCA-associated vasculitides (AAVs). The Vasculitis Damage Index (VDI) quantifies damage. This study aims to determine the factors associated with long-term damage in the AAVs.
Stress-Laminated Timber Decks Subjected to Eccentric Loads in the Ultimate Limit State
Stress-laminated timber (SLT) bridge decks are generally designed using either linear hand calculation methods or linear finite-element models. Several studies have shown, however, that the behavior of SLT decks is nonlinear when loaded until failure. In this paper, several linear design methods are compared with one another and with an ultimate load test of a full-scale SLT deck subjected to an e
Adherence to the mediterranean diet and risk of breast cancer in the European prospective investigation into cancer and nutrition cohort study
Epidemiological evidence suggests that the Mediterranean diet (MD) could reduce the risk of breast cancer (BC). As evidence from the prospective studies remains scarce and conflicting, we investigated the association between adherence to the MD and risk of BC among 335,062 women recruited from 1992 to 2000, in ten European countries, and followed for 11 years on average. Adherence to the MD was es

A Swedish national post-marketing surveillance study of natalizumab treatment in multiple sclerosis
Background: A post marketing surveillance study was conducted to evaluate safety and efficacy of natalizumab in Swedish multiple sclerosis (MS) patients since its introduction in August 2006 until March 2010. Methods: Patients were registered in the web-based Swedish MS-registry at 40 locations and evaluated every 6 months. Adverse events and clinical outcomes were recorded. Results: One thousand
In situ anodization of aluminum surfaces studied by x-ray reflectivity and electrochemical impedance spectroscopy
We present results from the anodization of an aluminum single crystal [Al(111)] and an aluminum alloy [Al 6060] studied by in situ x-ray reflectivity, in situ electrochemical impedance spectroscopy and ex situ scanning electron microscopy. For both samples, a linear increase of oxide film thickness with increasing anodization voltage was found. However, the slope is much higher in the single cryst
Unveiling the complex electronic structure of amorphous metal oxides
Amorphous materials represent a large and important emerging area of material's science. Amorphous oxides are key technological oxides in applications such as a gate dielectric in Complementary metal-oxide semiconductor devices and in Silicon-Oxide-Nitride-Oxide-Silicon and TANOS (TaN-Al2O3-Si3N4-SiO2-Silicon) flash memories. These technologies are required for the high packing density of today's
