Ethical considerations in chimera research.

The development of human pluripotent stem cells has opened up the possibility to analyse the function of human cells and tissues in animal hosts, thus generating chimeras. Although such lines of research have great potential for both basic and translational science, they also raise unique ethical issues that must be considered.

Hearing difficulties, uptake, and outcomes of hearing aids in people 85 years of age

Objective: The aim of this study was to investigate self-reported hearing difficulties, uptake, and hearing-aid outcomes and their relationships to demographic, cognitive, psychosocial, and health variables in 85 year olds. Design and study sample: Three hundred and forty-six elderly adults participated in a survey that included questionnaires and home visits. Fifty-five percent of participants ad

The Avian Transcriptome Response to Malaria Infection.

Malaria parasites are highly virulent pathogens which infect a wide range of vertebrates. Despite their importance, the way different hosts control and suppress malaria infections remains poorly understood. With recent developments in next generation sequencing techniques, however, it is now possible to quantify the response of the entire transcriptome to infections. We experimentally infected Eur

A thiol functionalized cryogel as a solid phase for selective reduction of a cysteine residue in a recombinant human growth hormone variant.

Site selective chemical modification is a preferred method, employed to prolong the circulation half-life of biopharmaceuticals. Cysteines have been used as attachment point for such modification, however, to be susceptible for chemical modification the involved thiol must be in its reduced form. Proteins often contain disulfides, which aid to maintain their tertiary structure and therefore must r

Aktionsart, word form and context: On the use of the active participle in Gulf Arabic dialects

Abstract in UndeterminedA line has been drawn between the dialects of Oman and those of the coastal Gulf states in classifications of the Arabic dialects of the Arabian Peninsula (Johnstone 1967; Holes 1989 Holes 1996). Most studies reporting on this divide have dealt with the phonology, morphology and, to some extent, lexis. Little is known, however, about the degree to which these dialectal grou

Low Levels of Circulating CD4+FoxP3+ T Cells Are Associated With an Increased Risk for Development of Myocardial Infarction But Not for Stroke.

OBJECTIVE: Regulatory T cells (Tregs) protect against atherosclerosis in experimental models, but their association with cardiovascular disease in humans remains to be elucidated. The aim of the present study was to determine whether circulating Tregs predict the development of acute cardiovascular events in humans. METHODS AND RESULTS: The study cohort consisted of a random sample of particip

Experimental Investigation of the Directional Outdoor-to-In-Car Propagation Channel

Abstract in UndeterminedThe demand for wireless channel models including realistic user environments is increasing. This motivates work on more detailed models that are reasonably simple and tractable but with adequatestatistical performance. In this paper, we present an investigation of the spatial outdoor-to-in-car radio channel at 2.6 GHz. Specifically, we investigate the performance of a multi

Single-molecule denaturation mapping of DNA in nanofluidic channels

Here we explore the potential power of denaturation mapping as a single-molecule technique. By partially denaturing YOYO (R)-1-labeled DNA in nanofluidic channels with a combination of formamide and local heating, we obtain a sequence-dependent "barcode" corresponding to a series of local dips and peaks in the intensity trace along the extended molecule. We demonstrate that this structure arises f

Forbidden-line spectroscopy of the ground-state configuration of Cd-like W

only using electric-dipole forbidden emission lines, in what we label forbidden-line spectroscopy, we identified several energy levels in cadmium-like tungsten, W26+. The spectrum was recorded at the Shanghai permanentmagnet electron beam ion trap in the visible region. The identifications were supported by large-scale multiconfiguration Dirac-Hartree-Fock calculations which involved careful inves

Assessing left ventricular systolic function in shock: evaluation of echocardiographic parameters in intensive care

Introduction: Assessing left ventricular (LV) systolic function in a rapid and reliable way can be challenging in the critically ill patient. The purpose of this study was to evaluate the feasibility and reliability of, as well as the association between, commonly used LV systolic parameters, by using serial transthoracic echocardiography (TTE). Methods: Fifty patients with shock and mechanical ve

Mercury (Hg) Transport in a High Arctic River in Northeast Greenland

In a warming climate, mercury (Hg) pathways in the Arctic can be expected to be affected. The Hg transport from the high arctic Zackenberg River Basin was assessed in 2009 in order to describe and estimate the mercury transported from land to the marine environment. A total of 95 water samples were acquired and filtered (0.4 mu m pore size), and Hg concentrations were determined in both the filter

Nocturnal migratory songbirds adjust their travelling direction aloft: evidence from a radiotelemetry and radar study.

In order to fully understand the orientation behaviour of migrating birds, it is important to understand when birds set their travel direction. Departure directions of migratory passerines leaving stopover sites are often assumed to reflect the birds' intended travel directions, but this assumption has not been critically tested. We used data from an automated radiotelemetry system and a tracking

Search for Supersymmetry Using Final States with One Lepton, Jets, and Missing Transverse Momentum with the ATLAS Detector in root s=7 TeV pp Collisions

This Letter presents the first search for supersymmetry in final states containing one isolated electron or muon, jets, and missing transverse momentum from root s = 7 TeV proton-proton collisions at the LHC. The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of 35 pb(-1). No excess above the standard model background expectation is observed.

Smoking in combination with antibodies to cyclic citrullinated peptides is associated with persistently high levels of survivin in early rheumatoid arthritis: a prospective cohort study

Introduction: High levels of the oncoprotein survivin may be detected in the majority of patients with early rheumatoid arthritis (RA). Survivin is a sensitive predictor of joint damage and persistent disease activity. Survivin-positive patients are often poor responders to antirheumatic and biological treatment. The aim of this study was to investigate the reproducibility of survivin status and i

Molecular characterisation of a recurrent, semi-cryptic RUNX1 translocation t(7;21) in myelodysplastic syndrome and acute myeloid leukaemia

P>A proportion of cytogenetic abnormalities in myelodysplastic syndromes (MDS) and acute myeloid leukaemia (AML) may escape detection by high-resolution genomic technologies, but can be identified by conventional cytogenetic and molecular analysis. Here, we report the detection of a reciprocal translocation t(7;21)(p22;q22) in the marrow of two adults with MDS and AML, using conventional cytogenet
