Polysulfones carrying benzoyl(difluoromethylenephosphonic acid) side chains were prepared and investigated for use as proton-conducting fuel-cell membranes. In the first step, polysulfones were lithiated and reacted with methyl iodobenzoates to prepare p- and o-iodobenzoyl polysulfones. Next, the phosphonated polysulfones were prepared via CuBr-mediated cross-coupling reactions between the iodinat
As ascites is related to liver cirrhosis in 80% of the patients, the present therapeutic guidelines are focused on ascites in liver cirrhosis. A combination of spironolactone and furosemide is recommended as first line therapy in patients with mild to moderate ascites and is effective in 90% of patients. In patients with pronounced or tense ascites, first line treatment is total paracentesis with
Apolipoprotein RI (apoM) is a novel apolipoprotein that is predominantly present in high-density lipoprotein, Sensitive sequence starches, threading and comparative model building experiments revealed apoM to be structurally related to the lipocalin protein family. In a 3D model, characterized by an eight-stranded anti-parallel beta -barrel, a segment including Asn135 could adopt a closed or open
Aims: To show the power of history science methods for exposure assessment in occupational health studies, using the dry cleaning industry in Denmark around 1970 as the example. Methods: Exposure data and other information on exposure status were searched for in unconventional data sources such as the Danish National Archives, the Danish Royal Library, archives of Statistics Denmark, the National
Between 20 and 30 per cent of all breast cancers show an overexpression of the growth factor HER2 and this implies a worse prognosis. Metastasising breast cancer that overexpress HER2 can effectively be treated with trastuzumab (Herceptin). In order to determine whether this treatment is indicated, HER2 expression must be quantified with immunohistochemical or molecular biological methods. Several
An error exponent for woven convolutional codes (WCC) with one tailbiting component code is derived. This error exponent is compared with that of the original WCC. It is shown that for WCC with outer warp, a better error exponent is obtained if the inner code is terminated with the tailbiting method. Furthermore, it is shown that the decoding error probability decreases exponentially with the squa
This paper gives an overview of the cadmium (Cd) situation in agricultural systems and human exposure in Sweden. Cadmium levels in agricultural soils (the plow layer) increase by 0.03% to 0.05% per year. Feed can give substantial contributions of Cd to local agricultural systems. Effects on human kidney function are indicated by some measurements already at today's exposure levels. If food product
The longitudinal spread zone was investigated for 30 arctic shorebird populations from 10 different wintering communities in widely different regions of both the Northern and Southern Hemispheres. Information about total breeding and wintering ranges, migratory connectivity and subspecies was compiled from literature sources. The spread of the distributions was analysed in relation to the mean dis
To evaluate whether the calcitonin gene-related peptide (CGRP) receptor antagonist telcagepant might be effective for migraine prevention.
BACKGROUND: Growth differentiation factor 15 (GDF15) belongs to the transforming growth factor beta superfamily and has been associated with activation of the p53 pathway in human cancer. The aim of this study was to assess the prognostic value of GDF15 in patients with colorectal cancer (CRC). METHODS: Immunohistochemistry and tissue microarrays were used to analyse GDF15 protein expression in 32
We present rapidly convergent expressions for the Green's function of the Poisson equation for spherically symmetric systems where the dielectric constant varies discontinuously in the radial direction. These expressions are used in Monte Carlo simulations of various electrolyte systems, and their efficiency is assessed. With only the leading term of the expansion included, a precision of the pola
The consistent modelling methodology for secondary settling tanks (SSTs) leads to a partial differential equation (PDE) of nonlinear convection–diffusion type as a one-dimensional model for the solids concentration as a function of depth and time. This PDE includes a flux that depends discontinuously on spatial position modelling hindered settling and bulk flows, a singular source term describing
Under scrutiny (what we term a “bribery gaze”), many interpersonal exchanges in work contexts are perceived as bribes rather than gifts, tokens of appreciation, or mundane favors. Current Swedish bribery laws are strong, and the media keep a vigilant eye out for suspicious activities. From a wide set of qualitative data, we selected 13 interviews with formally-accused middle managers and low-level
Carboxylic acids are important bulk chemicals that can be used as building blocks for the production of polymers, as acidulants, preservatives and flavour compound or as precursors for the synthesis of pharmaceuticals. Today, their production mainly takes place through catalytic processing of petroleum-based precursors. An appealing alternative would be to produce these compounds from renewable re
Abstract Resting metabolic rate is a common way of quantifying the cost of living in endothermic animals. The trait often makes up a substantial part of an animal's energy budget and can also be related to sustainable peak work rate as well as to daily energy expenditure. Studies have shown that metabolic rates are often heritable, but much of the variation seems to be caused by other factors (e.g
