A DNA Methylation Map of Human Atherosclerosis.

-Epigenetic alterations may contribute to the development of atherosclerosis. In particular, DNA methylation, a reversible and highly regulated DNA modification, could influence disease onset and progression since it functions as an effector for environmental influences, including diet and lifestyle, both of which are risk factors for cardiovascular diseases.

Density functional theory for Yukawa fluids

We develop an approximate field theory for particles interacting with a generalized Yukawa potential. This theory improves and extends a previous splitting field theory, originally developed for counterions around a fixed charge distribution. The resulting theory bridges between the second virial approximation, which is accurate at low particle densities, and the mean-field approximation, accurate

Works of art: Aesthetic Ambitions in Design Hotels

This paper analyzes a genre of hotels that has grown substantially the latest decades: namely one that includes hotels that go under names such as design hotels, boutique hotels, or "contemporary" hotels. It presents elements of the transnational discourse of this genre and shows how these are translated, materialized and localized. Individual hotels are used as illustrative examples of how discur

Risk of breast cancer among patients with bioprosthetic or mechanical valve replacement: a population-based study in Sweden.

The association between breast cancer and warfarin is inconclusive as most previous studies examined their association using patients with thromboembolism, whereas thromboembolism itself is a risk factor for cancer. We explored this issue using patients received mechanical heart valves replacement as a proxy for warfarin exposure as these patients need a lifelong warfarin treatment, and compared t

Synthesis and use of protein G imprinted cryogel as affinity matrix to purify protein G from cell lyaste.

Monolithic macroporous cryogel imprinted with protein G was prepared using a functional co-monomer of N-methacryloyl-l-phenylalanine and 2-hydroxyethyl methacrylate. The chemical structure of the cryogel prepared was studied by FTIR-spectroscopy and its porosity was analysed using scanning electron microscopy. The cryogel was used to purify protein G from recombinant Escherichia coli cell lysate a

Becoming 'culturpreneur': How the 'neoliberal regime of truth' affects and redefines artistic subject positions

In relating to the politico-economic concept of creative industries', the paper explores in what way the art field and its actors are discursively repositioned within flexible cultural capitalism'. Through empirical material from the independent Austrian theatre scene, the paper, moreover, illustrates how the culturpreneurial' transformation of the field affects the specific artistic practices, fo

Health Economic Analysis on a Psychosocial Intervention for Family Caregivers of Persons with Dementia.

Background/Aims: Psychosocial intervention has shown positive effects on the caregivers' burden and satisfaction. The aims of this study were to describe the cost and cost-effectiveness of such an intervention. Methods: We analyzed resource use and costs of formal care for 308 persons with dementia and their caregivers' health-related quality of life (HRQoL). Results: The costs of home help servic

Primary assembly of soil communities: disentangling the effect of dispersal and local environment.

It has long been recognised that dispersal abilities and environmental factors are important in shaping invertebrate communities, but their relative importance for primary soil community assembly has not yet been disentangled. By studying soil communities along chronosequences on four recently emerged nunataks (ice-free land in glacial areas) in Iceland, we replicated environmental conditions spat

InAs nanowire MOSFETs in three-transistor configurations: single balanced RF down-conversion mixers.

Integration of III-V semiconductors on Si substrates allows for the realization of high-performance, low power III-V electronics on the Si-platform. In this work, we demonstrate the implementation of single balanced down-conversion mixer circuits, fabricated using vertically aligned InAs nanowire devices on Si. A thin, highly doped InAs buffer layer has been introduced to reduce the access resista

Targeting Factor Replacement Therapy in Severe Hemophilia: Which Level Is Important?

The original aim of prophylactic replacement therapy was to convert the bleeding pattern of severe hemophilia to that of moderate hemophilia through regular infusions of clotting factor concentrates. However, targeting prophylaxis on minimum trough levels does not prevent all bleeding. At the group level, there is a clear association of factor levels with bleeding and outcome. But bleeding phenoty

Menopausal hormone use and ovarian cancer risk: individual participant meta-analysis of 52 epidemiological studies

Background Half the epidemiological studies with information about menopausal hormone therapy and ovarian cancer risk remain unpublished, and some retrospective studies could have been biased by selective participation or recall. We aimed to assess with minimal bias the effects of hormone therapy on ovarian cancer risk. Methods Individual participant datasets from 52 epidemiological studies were a

Preanesthetic nurse communication with children and parents-an observational study.

The impact of communication within the perioperative period is an area of increasing research interest. Suggestions are phrases or actions that can lead to subconscious nonvolitional changes in patient perception, mood, and/or behavior. Statements functioning as suggestions may induce positive or negative perceptual responses and experiences. Children and anxious patients are particularly responsi

Underlying Event measurements in pp collisions at root s=0.9 and 7 TeV with the ALICE experiment at the LHC

We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions coll

Influence of bone remodelling rate on quantitative ultrasound parameters at the calcaneus and DXA BMDa of the hip and spine in middle-aged and elderly European men: the European Male Ageing Study (EMAS)

Objective: To assess the influence of sex hormones on markers of bone turnover and to explore the association between these markers and bone health in middle-aged and elderly European men. Design: A cross-sectional population-based survey. Methods: Men aged 40-79 years were recruited from population registers in eight European centres. Subjects completed a postal questionnaire which included quest

Risk Contagion among International Stock Markets

Abstract in UndeterminedWe develop a stochastic volatility model with jumps in returns and volatility to analyze the risk spillover from the U.S. market and the regional market to a number of European countries' equity markets. The key advantage of this approach compared to the earlier approaches is that it enables us to identify jumps and investigate spillover of extreme events across borders. We

Combined effects of age of onset and input on the development of different grammatical structures: A study of simultaneous and successive acquisition of French

This study investigates the combined effects of Age of Onset of Acquisition (AOA) and quality and quantity of input on the development of three grammatical structures in French. In a longitudinal and multiple case study including successive (L2) Swedish-French bilingual children (n=3), simultaneous (2L1) Swedish-French bilingual children (n=3) and monolingual French children (n=3), we examine the
