Air pollution control and decreasing new particle formation lead to strong climate warming

The number concentration of cloud droplets determines several climatically relevant cloud properties. A major cause for the high uncertainty in the indirect aerosol forcing is the availability of cloud condensation nuclei (CCN), which in turn is highly sensitive to atmospheric new particle formation. Here we present the effect of new particle formation on anthropogenic aerosol forcing in present-d

Cationic and anionic lipid-based nanoparticles in CEC for protein separation.

The development of new separation techniques is an important task in protein science. Herein, we describe how anionic and cationic lipid-based liquid crystalline nanoparticles can be used for protein separation. The potential of the suggested separation methods is demonstrated on green fluorescent protein (GFP) samples for future use on more complex samples. Three different CEC-LIF approaches for

Clonal variegation and dynamic competition of leukemia-initiating cells in infant acute lymphoblastic leukemia with MLL rearrangement.

Distinct from most other acute lymphoblastic leukemia (ALL), infant ALL with mixed lineage leukemia (MLL) gene rearrangement, the most common leukemia occurring within the first year of life, might arise without the need for cooperating genetic lesions. Through Ig/TCR rearrangement analysis of MLL-AF4+ infant ALL at diagnosis and xenograft leukemias from mice transplanted with the same diagnostic

Comparing Health Outcomes and Costs of General Vaccination with Pneumococcal Conjugate Vaccines in Sweden: A Markov Model

Background: Two new pneumococcal conjugate vaccines were licensed to immunize infants and young children against pneumococcal disease. Objectives: The objective of this study was to estimate the expected health benefits, costs, and incremental cost-effectiveness of routine vaccination with the 10-valent pneumococcal nontypeable hemophilus influenza protein-D conjugate vaccine (PHiD-CV) compared wi

FoxJ1-expressing cells contribute to neurogenesis in forebrain of adult rats: Evidence from in vivo electroporation combined with piggyBac transposon.

Ependymal cells in the lateral ventricular wall are considered to be post-mitotic but can give rise to neuroblasts and astrocytes after stroke in adult mice due to insult-induced suppression of Notch signaling. The transcription factor FoxJ1, which has been used to characterize mouse ependymal cells, is also expressed by a subset of astrocytes. Cells expressing FoxJ1, which drives the expression o

Rotational CARS thermometry in diffusion flames: On the influence of nitrogen spectral line-broadening by CH4 and H-2

Rotational CARS N-2 thermometry has been developed for improved accuracy in spatial flame regions with high concentrations of either H-2 or CH4, which are typical conditions on the fuel side of diffusion flames. In initial validation experiments up to 700 K, rotational CARS measurements were performed in binary mixtures of H-2 and N-2. Subsequent spectral evaluation with commonly used N-2-N-2 Rama

Autosomal dominant Parkinson's disease caused by SNCA duplications.

The discovery in 1997 that mutations in the SNCA gene cause Parkinson's disease (PD) greatly advanced our understanding of this illness. There are pathogenic missense mutations and multiplication mutations in SNCA. Thus, not only a mutant protein, but also an increased dose of wild-type protein can produce autosomal dominant parkinsonism. We review the literature on SNCA duplications and focus on

Formation of Ternary Metal-Oxalate Surface Complexes on alpha-FeOOH Particles

Processes at the aqueous interfaces of metal (hydr)oxide particles greatly influence the mobility, bioavailability, and reactivity of metal ions and ligands. Here we investigated the time-dependent reactions of oxalate or Me(C(2)O(4))(3)(3-) (Me = Fe(III), Al(III), Ga(III), Co(III)) with goethite in aqueous suspension at pH 4 using attenuated total reflectance infrared (ATR-IR) and extended X-ray

Somatosensory impairments are common after stroke but have only a small impact on post-stroke shoulder pain.

Objective: To investigate whether somatosensory impairments are more common in individuals with post-stroke shoulder pain than in those without post-stroke shoulder pain and healthy controls. Design: Descriptive analysis of a convenience sample. Participants: Forty-nine individuals with stroke, 24 with and 25 without post-stroke shoulder pain (median age 65 years), and 11 age- and sex-matched heal

From a reactive to a proactive safety approach. Analysis of medication errors in chemotherapy using general failure types

A better understanding of why medication errors (MEs) occur will mean that we can work proactively to minimise them. This study developed a proactive tool to identify general failure types (GFTs)in the process of managing cytotoxic drugs in healthcare. The tool is based on Reason’s Tripod Delta tool. The GFTs and active failures were identified in 60 cases of MEs reported to the Swedish national a

Comments: The role of attention in lexical semantics

I take up the roles of the world, the mind and the society in my semantic theory. I show how semantic differences between languages can be seen as attending to different parts of event structures. The role of the emotion domain in relation to the meaning of pejoratives is discussed. Finally, the idea that articles in language should be seen as an extension of pointing is shown to be congenial with

The PLATO 2.0 mission

PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addresses fundamental questions such as: How do planetary systems form and evolve? Are there other systems with planets like ours, including potentially habitable planets? The PLATO 2.0 instrument consists of 34 small ap

Immune response to an endotoxin challenge involves multiple immune parameters and is consistent among the annual-cycle stages of a free-living temperate zone bird

Trade-offs between immune function and other physiological and behavioural processes are central in ecoimmunology, but one important problem is how to distinguish a reallocation of resources away from the immune system from a reallocation or redistribution within the immune system. While variation in baseline values of individual immune parameters is well established, studies in wild animals on mu

APC resistance due to Factor V Leiden is not related to baseline inflammatory mediators or survival up to 10 years in patients with critical limb ischemia.

To prospectively evaluate the potential influence of resistance to activated protein C (APC-resistance) on the initial inflammatory response, amputation rate and survival during 10 years of follow-up in patients with critical limb ischemia (CLI). Two hundred and fifty-six consecutive CLI patients were analyzed for APC-ratio, the Factor V Leiden mutation and inflammatory mediators and then prospect

Antiferromagnetic Heisenberg Spin Chain of a Few Cold Atoms in a One-Dimensional Trap.

We report on the deterministic preparation of antiferromagnetic Heisenberg spin chains consisting of up to four fermionic atoms in a one-dimensional trap. These chains are stabilized by strong repulsive interactions between the two spin components without the need for an external periodic potential. We independently characterize the spin configuration of the chains by measuring the spin orientatio

International stock market interdependence: Are developing markets the same as developed markets?

This paper uses a dynamic panel-data gravity model to explain the correlations between 40 markets from 1996 to 2010 using four types of market linkages: information capacity, financial integration, economic integration, and similarity in industrial structure. The mechanism of interdependence of developed markets and that of developing markets are heterogeneous: (1) information capacity and industr
