Calcium mediated interaction of calf-thymus DNA with monolayers of distearoylphosphtidylcholine: a neutron and Xray reflectivity study

X-ray and neutron reflection studies, the latter in conjunction with contrast variation, have been combined to study the interaction of calf thymus DNA (ctDNA) with monolayers of distearoylphosphatidylcholine (DSPC) in the presence of 20 mM Ca2+ ions, at the air–liquid interface as a function of surface pressure (10, 20, 30 and 40 mN m−1). Analysis of the X-ray and neutron reflection data showed t

Use of a trabecular metal implant in ankle arthrodesis after failed total ankle replacement

Patients and methods 13 patients with a migrated or loose total ankle implant underwent arthrodesis with the use of a retrograde intramedullary nail through a trabecular metal Tibial Cone. The mean follow-up time was 1.4 (0.6-3.4) years. Results At the last examination, 7 patients were pain-free, while 5 had some residual pain but were satisfied with the procedure. 1 patient was dissatisfied and e

Malnutrition and risk of falling among elderly without home-help service - A cross sectional study

Objectives: The aim of this study was to explore the frequency of malnutrition risk and associated risk of falling, social and mental factors among elderly without home-help service. The aim was also to explore factors associated with risk of falling. A cross-sectional design was used. Elderly persons own homes. Data were collected during preventive home visits to 565 elderly (age range 73-90 year

The intrinsic GTPase activity of the Gtr1 protein from Saccharomyces cerevisiae

Background: The Gtr1 protein of Saccharomyces cerevisiae is a member of the RagA subfamily of the Ras-like small GTPase superfamily. Gtr1 has been implicated in various cellular processes. Particularly, the Switch regions in the GTPase domain of Gtr1 are essential for TORC1 activation and amino acid signaling [R. Gong, L. Li, Y. Liu, P. Wang, H. Yang, L. Wang, J. Cheng, K. L. Guan, Y. Xu, Genes De

The variation of daylight levels across atrium walls: Reflectance distribution and well geometry effects under overcast sky conditions

Daylight plays a major role in making atrium spaces appealing to building users. This appeal is also evident in the spaces adjoining the atrium. A key component of atrium daylighting, especially in tall atria, is the daylight reflected on to the atrium walls. This study examines the impacts of well geometries and different diffuse reflectance distributions of walls on variations of vertical intern

Assessing ozone exposure for epidemiological studies in Malmo and Umea, Sweden

Ground level ozone [ozone] is considered a harmful air pollutant but there is a knowledge gap regarding its long term health effects. The main aim of this study is to develop local Land Use Regression [LUR] models that can be used to study long term health effects of ozone. The specific aim is to develop spatial LUR models for two Swedish cities, Umea and Malmo, as well as a temporal model for Mal

BACE1 gene variants do not influence BACE1 activity, levels of APP or A beta isoforms in CSF in Alzheimer's disease

The BACE1 gene encodes the beta-site APP-cleaving enzyme 1 and has been associated with Alzheimer's disease (AD). BACE1 is the most important beta-secretase responsible for the generation of Alzheimer-associated amyloid beta-proteins (A beta) and may play a role in the amyloidogenic process in AD. We hypothesized that BACE1 gene variants might influence BACE1 activity or other markers for APP meta

Photoreceptor rescue and toxicity induced by different calpain inhibitors

P>Photoreceptor degeneration is the hallmark of a group of inherited blinding diseases collectively termed retinitis pigmentosa (RP); a major cause of blindness in humans. RP is at present untreatable and the underlying neurodegenerative mechanisms are largely unknown, even though the genetic causes are often established. The activation of calpain-type proteases may play an important role in cell

Different arbuscular mycorrhizae and competition with an exotic grass affect the growth of Podocarpus cunninghamii Colenso cuttings

There is growing interest in the use of arbuscular mycorrhizal fungi (AMF) for ecological restoration. Numerous commercial AMF products are now available and are often used in preference to collecting indigenous AMF in treating restoration plants. Commercial AMF products are typically based on AMF strains exotic to the plant species and locations where they are used. We treated rooted cuttings of

The Path Dependence of European Copyright.

This article analyses the path dependence of European copyright. It shows how copyright is legally constructed, is harmonised through international treaties and European regulatory efforts in terms of InfoSoc Directive and the IPRED, and is also affected by the Data Retention Directive and the Telecommunications Reform package. Furthermore, the “secretly” negotiated ACTA agreement is discussed as

Generalized Elastic Flow Rerouting Scheme

The present study deals with Elastic Flow Rerouting (EFR)-an original traffic restoration strategy for protecting traffic flows in communication networks (including wireless networks) against multiple link failures. EFR aims at alleviating the trade-off between practicability of traffic restoration and the cost of network resources observed in existing networking solutions. We present an extension
