Low dose Zebularine treatment enhances immunogenicity of tumor cells

Strategy: We have investigated how alterations in gene expression induced by the demethylating drug Zebularine affect the immune response tumor cells elicit. The rational has been to treat syngeneic rat colon cancer cells with Zebularine at different concentrations and then use these cells to study gene expression of different genes involved in cancer immunogenicity. Gene expressions were monitore

Cytokeratin 5/14-positive breast cancer: true basal phenotype confined to BRCA1 tumors

Breast ducts contain two types of epithelial cells, inner luminal cells and outer basal/ myoepithelial cells. These cells can be distinguished by their immunophenotype. Cytokeratins ( CKs) 8 and 18 are expressed in the luminal layer, whereas CK5/ 14 and the transcription factor p63 characterize the basal epithelial layer. We studied a population- based cohort of 288 sporadic ductal invasive cancer

Influence of the compression ratio on the performance and emissions of a mini HCCI engine fuelled with diethyl ether

Power supply systems play a very important role in applications of everyday life. Mainly, for low power generation, there are two ways of producing energy: electrochemical batteries and small engines. In the last few years many improvements have been carried out in order to obtain lighter batteries with longer duration but unfortunately the energy density of 1 MJ/kg seems to be an asymptotic value

Resistant starch content in a selection of starchy foods on the Swedish market.

OBJECTIVE: The objective was to determine the resistant starch (RS) content in a selection of typical starchy foods on the Swedish market. In addition, the daily RS intake was estimated from Swedish food consumption data. DESIGN: The major forms of RS, including physically encapsulated starch, were determined with an in vitro method using chewing as a pre-step before enzymatic incubation. SETTING:

Isospin symmetry brealdng in Tc-93 and statistical properties

We present a statistical analysis of proton resonances in the compound nucleus Tc-93 in terms of random matrix theory (RMT). The fluctuation properties of energy levels and reduced widths from data measured by Bilpuch et al. [Phys. Rev. C 9 (1974) 1589] are studied. We conclude that one T> = 9/2 isobaric analog state does not affect the spectral correlations of a sequence of 124 T< = 7/2 states, a

Energy transfer in ZnWO4 and CdWO4 scintillators

A systematic spectroscopic study of oriented single ZnWO4 crystals was performed using UV and synchrotron excitation. Emission and phosphorescence spectra in the energy region 1-4 eV as well as reflection spectra and excitation spectra of various emissions and phosphorescence in the energy region 3.5-32eV were studied at 4.2-300K using synchrotron radiation. The results are compared to those avail

Search for odderon-induced contributions to exclusive pi(0) photoproduction at HERA

A search for contributions to the reaction ep --> epi(0)N* from photon-odderon fusion in the photoproduction regime at HERA is reported, at an average photon-proton centre-of-mass energy = 215 GeV. The measurement proceeds via detection of the pi(0) decay photons, a leading neutron from the N* decay, and the scattered electron. No pi(0) signal is observed and an upper limit on the cross section f

Reliability-based assessment procedures for existing concrete structures

Popular Abstract in Swedish Möjligheten att använda tillförlitlighetsteori som ett verktyg för utvärdering av säkerhet och återstående livslängd av skadade konstruktioner har undersökts. Det framkommer att tillgängliga riktlinjer och stödjande dokument är öppna för tolkningar och detta leder till resultat med oacceptabla skillnader. Tolkningar förkommer även vid deterministiska beräkningar men tilA feasibility study of reliability theory as a tool for the assessment of present safety and residual service life of damaged concrete structures has been performed in order to find a transparent methodology for the assessment procedure. It is concluded that the current guidelines are open to interpretation and that the variation in the results obtained regarding the structural safety is too grea

Structural insights into fusidic acid resistance and sensitivity in EF-G

Fusidic acid (FA) is a steroid antibiotic commonly used against Gram positive bacterial infections. It inhibits protein synthesis by stalling elongation factor G (EF-G) on the ribosome after translocation. A significant number of the mutations conferring strong FA resistance have been mapped at the interfaces between domains G, III and V of EF-G. However, direct information on how such mutations a

Using simulation for assessing the real impact of test coverage on defect coverage

The use of test coverage measures (e.g., block coverage) to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test coverage helps achieve higher defect coverage and therefore improves software quality. In practice, data often shows that defect coverage and test coverage grow over time, as additional testing is performed. H

An automatic method to generate force-field parameters for hetero-compounds.

A method has been developed that automatically constructs a crystallographic refinement force field (topology and parameter files) for any molecule from a theoretical frequency calculation. The approach has been tested on five proteins containing metal sites or non-standard inhibitors or coenzymes and it is shown that the structures are improved in various aspects.

Dead-Ice Under Different Climate Conditions: Processes, Landforms, Sediments and Melt Rates in Iceland and Svalbard

Popular Abstract in Swedish Recenta dödismiljöer framför Brúarjökull-glaciären på Island och Holmströmbreen på Svalbard har undersökts med speciellt fokus på landforms- och sedimentgenes samt kvantifiering av dödisavsmältningen. Fältmätningar, studier av tidsserier av flyg? och satellitbilder samt digitala terrängmodeller är dataunderlaget för kvantifieringen av dödisavsmältningen. SedimentologiskModern dead-ice environments in the glacier forefields of Brúarjökull, Iceland and Holmströmbreen, Svalbard were investigated with focus on landform and sediment genesis, as well as quantification of melting. Field monitoring and studies of multi-temporal aerial photographs, satellite imagery, and Digital Elevation Models (DEMs) provided data for the melting quantification. Sedimentological and ge

Increased mortality after anterior shoulder dislocation - 255 patients aged 12-40 years followed for 25 years

Background No data exist regarding mortality rate in young patients with a first-time anterior shoulder dislocation. A cohort of 255 patients aged 1240 years had a primary anterior shoulder dislocation during the years 1978 and 1979. After 10 years, 9 of the patients had died-which is a high figure for this cohort of patients. The question thus arose as to whether these patients had an increased m

When Swedes begin to learn German: From V2 to V2

This article investigates verb placement, especially verb second (V2), in post-puberty L2 learners of two closely related Germanic V2-languages, Swedish and German. Håkansson, Pienemann & Sayehli (2002) have adduced data from L1 Swedish-speaking learners of German in support of the claim that the syntactic property of V2 never transfers from the L1 to L2 interlanguage grammars. Regardless of L

Morbidity and mortality among foreign-born Swedes

Popular Abstract in Swedish Det svenska samhället har under senare delen av 1900-talet påverkats och förändrats på grund av en ökad internationell migration. År 1950 var 2,8 % av den svenska befolkningen utrikesfödd; idag utgör de utrikesfödda 12,0 % av totalbefolkningen. Om även andragenerationens migranter (de som har en eller båda föräldrar utrikesfödda) räknas med utgör första och andrageneratAims: The general aim of this thesis was to describe and compare the group of foreign-born persons living in Sweden and native Swedes with regard to health development over time, thus studying the influence of migration on health. Methods: All four studies are based on data from Statistics Sweden (SCB) and the National Board of Health and Welfare, Centre for Epidemiology covering the period 1970?
