The Effect of Breast Positioning on Breast Compression in Mammography: a Pressure Distribution Perspective

The standard procedure at mammography is to compress the breast in order to improve image quality, better separate tissue components and reduce absorbed dose to the breast. Traditionally, compression guidelines have been based on applied force, rather than actual thickness reduction. Structures such as the pectoral muscle are stiffer than breast tissue and if compressed along with it, as in the ML

Features of the Nyström method for the Sherman-Lauricella equation on Piecewise Smooth Contours

The stability of the Nyström method for the Sherman-Lauricella equation on contours with corner points $c_j$, $j=0,1,...,m$ relies on the invertibility of certain operators $A_{c_j}$ belonging to an algebra of Toeplitz operators. The operators $A_{c_j}$ do not depend on the shape of the contour, but on the opening angle $\theta_j$ of the corresponding corner $c_j$ and on parameters of the approxim

Dynamics of wave fluctuations in the homogeneous Yang-Mills condensate

In the present work, the Yang-Mills (YM) quantum-wave excitations of the classical homogeneous YM condensate have been studied in quasi-classical approximation. The formalism is initially formulated in the Hamilton gauge and is based upon canonical quantisation in the Heisenberg representation. This canonical framework is then extended and related to YM dynamics in arbitrary gauge and symmetry gro

Assessment and analysis of housing accessibility: adapting the environmental component of the housing enabler to United States applications.

The home environment is a primary context for daily activities, especially among older adults and persons with disabilities. Functional and age-related decline can generate problems in relation to certain environmental features, necessitating modifications or other provisions of support. The determination of appropriate home interventions is best served using a person–environment (P–E) fit approac

The effect of medication reconciliation in elderly patients at hospital discharge.

Objective To assess the impact of medication reconciliation interventions on medication error rates when elderly patients are discharged from hospital to community care or nursing homes.Setting Elderly patients (>65 years) living in nursing homes or in their own homes with care provided by the community nursing system. Method All medical records containing information on drug treatment were collec

Infection-induced coronary dysfunction and systemic inflammation in piglets are dampened in hypercholesterolemic milieu

Birck MM, Pesonen E, Odermarsky M, Hansen AK, Persson K, Frikke-Schmidt H, Heegaard PM, Liuba P. Infection-induced coronary dysfunction and systemic inflammation in piglets are dampened in hypercholesterolemic milieu. Am J Physiol Heart Circ Physiol 300: H1595-H1601, 2011. First published February 25, 2011; doi:10.1152/ajpheart.01253.2010.-The synergism of infection with conventional cardiovascula

Stereotyped B-cell receptors in one-third of chronic lymphocytic leukemia: a molecular classification with implications for targeted therapies

Mounting evidence indicates that grouping of chronic lymphocytic leukemia (CLL) into distinct subsets with stereotyped BCRs is functionally and prognostically relevant. However, several issues need revisiting, including the criteria for identification of BCR stereotypy and its actual frequency as well as the identification of "CLL-biased" features in BCR Ig stereotypes. To this end, we examined 75

Pentamethylcyclopentadienyl-rhodium and iridium complexes containing (N^N and N^O) bound chloroquine analogue ligands: synthesis, characterization and antimalarial properties.

The synthesis and characterization of twenty new pentamethylcyclopentadienyl-rhodium and iridium complexes containing N^N and N^O-chelating chloroquine analogue ligands are described. The in vitro antimalarial activity of the new ligands as well as the complexes was evaluated against the chloroquine sensitive (CQS) NF54 and the chloroquine resistant (CQR) Dd2 strains of Plasmodium falciparum. The

Altered expression and distribution of cathepsins in neuronopathic forms of Gaucher disease and in other sphingolipidoses

The neuronopathic forms of the human inherited metabolic disorder, Gaucher disease (GD), are characterized by severe neuronal loss, astrogliosis and microglial proliferation, but the cellular and molecular pathways causing these changes are not known. Recently, a mouse model of neuronopathic GD was generated in which glucocerebrosidase deficiency is limited to neural and glial progenitor cells. We

TCF7L2 is a master regulator of insulin production and processing.

Genome-wide association studies have revealed >60 loci associated with type 2 diabetes (T2D), but the underlying causal variants and functional mechanisms remain largely elusive. Although variants in TCF7L2 confer the strongest risk of T2D among common variants by presumed effects on islet function, the molecular mechanisms are not yet well understood. Using RNA-sequencing, we have identified a TC

Nonmyelinating Schwann Cells Maintain Hematopoietic Stem Cell Hibernation in the Bone Marrow Niche

Hematopoietic stem cells (HSCs) reside and self-renew in the bone marrow (BM) niche. Overall, the signaling that regulates stem cell dormancy in the HSC niche remains controversial. Here, we demonstrate that TGF-beta type II receptor-deficient HSCs show low-level Smad activation and impaired long-term repopulating activity, underlining the critical role of TGF-beta/Smad signaling in HSC maintenanc

Number size distributions and seasonality of submicron particles in Europe 2008-2009

Two years of harmonized aerosol number size distribution data from 24 European field monitoring sites have been analysed. The results give a comprehensive overview of the European near surface aerosol particle number concentrations and number size distributions between 30 and 500 nm of dry particle diameter. Spatial and temporal distribution of aerosols in the particle sizes most important for cli

On the Minimum Distance of Generalized Spatially Coupled LDPC Codes

Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes. It has previously been shown that ensembles of GSC-LDPC codes constructed from a protograph have better iterative decoding thresholds than their block code counterparts, and that, for large termination lengths, the

Can the sectoral New Keynesian Phillips curve explain inflation dynamics in the Euro Area?

There is no a priori reason to suppose that price-setting behaviour is homogeneous across sectors and countries. Aggregate data are, however, commonly used to estimate the New Keynesian Phillips curve (NKPC), which may very well yield erroneous results if price-setting behaviour is heterogeneous. In this paper, we therefore estimate the hybrid NKPC for the Euro Area using a novel sectoral data set

Coupled Folding-Binding in a Hydrophobic/Polar Protein Model: Impact of Synergistic Folding and Disordered Flanks

Coupled folding-binding is central to the function of many intrinsically disordered proteins, yet not fully understood. With a continuous three-letter protein model, we explore the free-energy landscape of pairs of interacting sequences and how it is impacted by 1), variations in the binding mechanism; and 2), the addition of disordered flanks to the binding region. In particular, we focus on two
