Clinical outcome of percutaneous RF-ablation of non-operable patients with liver metastasis from breast cancer

Despite improved anti-neoplastic treatment the prognosis for patients with liver metastases from metastatic breast cancer remains poor. Thirty-two consecutive patients with metastatic breast cancer treated with radiofrequency ablation (RFA) at the Department of Oncology, Herlev Hospital, University of Copenhagen, from 1996 to 2010. Time to intrahepatic progression was median 11 months (range 1.6-1

Measurements of the Nuclear Modification Factor for Jets in Pb+Pb Collisions at sqrt[s_{NN}]=2.76 TeV with the ATLAS Detector.

Measurements of inclusive jet production are performed in pp and Pb+Pb collisions at sqrt[s_{NN}]=2.76 TeV with the ATLAS detector at the LHC, corresponding to integrated luminosities of 4.0 and 0.14 nb^{-1}, respectively. The jets are identified with the anti-k_{t} algorithm with R=0.4, and the spectra are measured over the kinematic range of jet transverse momentum 32

Link N is Cleaved by Human Annulus Fibrosus Cells Generating a Fragment With Retained Biological Activity

Presently, there are no established treatments to prevent, stop or even retard back pain arising from disc degeneration. Previous studies have shown that Link N can act as a growth factor and stimulate the synthesis of proteoglycans and collagens, in IVD. However, the sequences in Link N involved in modulating cellular activity are not well understood. To determine if disc cells can proteolyticall

Reduction of the putative CD44+CD24- breast cancer stem cell population by targeting the polyamine metabolic pathway with PG11047.

Cancer stem cells (CSCs) are considered to be of particular concern in cancer as they possess inherent properties of self-renewal and differentiation, along with expressing certain genes related to a mesenchymal phenotype. These features favour the promotion of tumour recurrence and metastasis in cancer patients. Thus, the optimal chemotherapeutic treatment should target the CSC population, either

Mutation-induced fold switching among lattice proteins.

Recent experiments uncovered a mutational pathway between two proteins, along which a single mutation causes a switch in fold. Searching for such paths between real proteins remains, despite this achievement, a true challenge. Here, we analyze fold switching in the minimalistic hydrophobic/polar model on a square lattice. For this analysis, we generate a comprehensive sequence-structure database f

Thermophilic biohydrogen production: how far are we?

Apart from being applied as an energy carrier, hydrogen is in increasing demand as a commodity. Currently, the majority of hydrogen (H2) is produced from fossil fuels, but from an environmental perspective, sustainable H2 production should be considered. One of the possible ways of hydrogen production is through fermentation, in particular, at elevated temperature, i.e. thermophilic biohydrogen pr

Revealing the size, conformation, and shape of casein micelles and aggregates with asymmetrical flow field-flow fractionation and multiangle light scattering.

Casein (CN) micelles are naturally occurring colloidal protein aggregates present in a dispersed state in milk. In this paper we aim to obtain a detailed description of physicochemical properties of CN micelles over the entire size distribution using asymmetrical flow field-flow fractionation (AsFlFFF) connected to multiangle light scattering (MALS) and refractive index (RI) detection. Conclusions

Accounts of Honesty. Refuting Allegations of Bribery

This article investigates the stories told by Swedish men charged with bribery. The interviews are drawn from a study of court cases relating to bribery. White-collar criminals often justify their actions with reference to business culture: ‘‘Everyone’s doing it.’’ In this study, when refuting alle- gations, interviewees also invoke a ‘‘folk logic of bribery,’’ thus making use of mainstream cultur

A distributed two-pore model: theoretical implications and practical application to the glomerular sieving of Ficoll

In the present study, an extended two-pore theory is presented where the porous pathways are continuously distributed according to small-and large-pore mean radii and SDs. Experimental glomerular sieving data for Ficoll were analyzed using the model. In addition, several theoretical findings are presented along with analytic solutions to many of the equations used in distributed pore modeling. The

C-reactive protein and leucocyte counts drop faster using the HeartShield® device in patients with DSWI.

Right ventricular heart rupture is a devastating complication associated with negative pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier disc (HeartShield™) has been suggested to offer protection against this lethal complication by preventing the heart from being drawn up by the negative pressure and damaged by the sharp sternum bone edges. Seven patients treated with co

Nova1 is a master regulator of alternative splicing in pancreatic beta cells.

Alternative splicing (AS) is a fundamental mechanism for the regulation of gene expression. It affects more than 90% of human genes but its role in the regulation of pancreatic beta cells, the producers of insulin, remains unknown. Our recently published data indicated that the 'neuron-specific' Nova1 splicing factor is expressed in pancreatic beta cells. We have presently coupled specific knockdo

Model validation image data for breakup of a liquid jet in crossflow: part I

We have applied three different imaging diagnostics: particle imaging velocimetry, high-speed shadowgraphy, and ballistic imaging, to observe the breakup of a liquid jet in a crossflow of air under a variety of conditions. The experimental system was designed to provide well-controlled conditions with minimal amounts of turbulence in the liquid jet and the gaseous crossflow. A variety of Weber num

Age- and time-dependent changes in cancer incidence among immigrants to Sweden: colorectal, lung, breast and prostate cancers

To examine the role of gender, age at immigration and length of stay on incidence trends of common cancers, we studied risk of colorectal, lung, breast and prostate cancers in immigrants to Sweden from 1958 to 2008. The nationwide Swedish Family-Cancer Database was used to calculate standardized incidence ratios for common cancers among immigrants compared to Swedes. Immigrants were classified int

Molecular imprinting of protein in Pickering emulsion.

A new strategy of molecular imprinting to prepare spherical hydrogels via water-in-oil Pickering emulsion polymerization was developed. The imprinted hydrogels exhibited fast adsorption kinetics and significant selectivity for the target protein.

Experimental wavelengths for intrashell transitions in tungsten ions with partially filled 3p and 3d subshells

Spectra and measured wavelengths of intrashell n = 3 transitions in highly charged tungsten ions with partially filled 3p and 3d valence shells, Al-like W61+ through Fe-like W48+, are presented. The ions were created and excited at the electron-beam ion-trap facility at the Lawrence Livermore National Laboratory and measured with a high-resolution grazing-incidence spectrometer. The spectral lines

A reflection on Richard B. Saltman 'Structural patterns in Swedish health policy

Looking back over 30 years of Swedish health care, professor Saltman examines structural changes in the Swedish health care sector. This is a very welcome contribution to the literature, and it makes good sense – institutional change is often a slow process, and it may take considerable time before the effects can be fully appreciated. Saltman’s paper provides a useful analytical overview of thre
