Background: Tumor microenvironment, which is largely affected by inflammatory cells, is a crucial participant in the neoplastic process through promotion of cell proliferation, survival and migration. We measured the effects of polymorphonuclear neutrophil (PMN) conditioned medium alone, and supplemented with serine proteinase inhibitor α-1 antitrypsin (AAT) or its C-terminal fragment (C-36 peptid
The aim of this work is to develop a method for detection of brief episode paroxysmal atrial fibrillation (PAF). The proposed method utilizes four different features: RR interval irregularity, absence of P waves, presence of f-waves and noise level. The obtained features are applied to the Mamdani-type fuzzy inference method for decisionmaking. The performance was evaluated on one hundred 90 s lon
Class Ib ribonucleotide reductases (RNR) utilize a di-nuclear manganese or iron cofactor for reduction of superoxide or molecular oxygen, respectively. This generates a stable tyrosyl radical (Y·) in the R2 subunit (NrdF), which is further used for ribonucleotide reduction in the R1 subunit of RNR. Here, we report high-resolution crystal structures of Bacillus anthracis NrdF in the metal-free form
We study the process gg → bb̄H+H- at large tanβ, where it represents the dominant production mode of charged Higgs boson pairs in a Type II 2-Higgs doublet model, including the minimal supersymmetric standard model. The ability to select this signal would in principle enable the measurements of some triple-Higgs couplings, which in turn would help understanding the structure of the extended Higgs
The objective of this study was to create a superhydrophobic surface using polymers that are non-fluorinated and applying them to a surface via rapid expansion of a supercritical solution (RESS). Solubility studies of poly(epsilon-caprolactone) (PCL) and a statistical copolymer of vinyl acetate and vinyl pivalate (P(VAc-VPi))in supercritical carbon dioxide (scCO(2)) were carried out using an extra
Popular Abstract in Swedish Människans arvsmassa består av DNA. DNA i sin tur består av nukleotiderna A, T, G och C som i olika kombinationer bygger upp våra gener. Människans "genom" (hela arvsmassa) består av uppåt 100 000 gener och varje gen kodar för ett protein som i sin tur är byggstenarna i våra kroppar. Eftersom DNA är en oerhört lång molekyl och cellerna är väldigt små (ca 10 micrometer) Chromosomal translocations commonly result in the production of fusion genes and the fusion genes are often tumor-type specific. In myxoid and round cell liposarcomas (MLS/RCLS), almost 95% of the cases carry a t(12;16)(q13;p11). In the remaining 5% of the MLS/RCLS tumors, another translocation and fusion gene can be found, i.e. the t(12;22)(q13;q12). These translocations fuse CHOP on chromosome 1
The procurement process can be defined as all the activities required in getting a product or a service from the supplier to a final destination. It encompasses the purchasing function, storing, transportation and manages the relations between suppliers and internal customers. It is a cyclical process involving the following activities: analysis, planning, implementation, and measurement. The perf

Popular Abstract in English My dissertation is a Swedish history of ideas 1965-2010 as expressed in the best-selling and most influential Swedish police novels and films. The title is "The Cop in the Twilight Land. Swedish Police Narratives in Novels and Film 1965-2010". Here I elaborate on the analysis briefly treated in the essay "Skymningslandet" ("Twilight Land") in the anthology "SolskenslandThe dissertation "The Cop in the Twilight Land: Swedish Police Narratives 1965-2010" considers Swedish culture and ideas in the period 1965-2010 as expressed in detective fiction and film in the tradition of Maj Sjöwall and Per Wahlöö. It takes the Swedish police narrative tradition to be part and parcel of the European history of ideas and culture; a history that necessarily comprises America, by
Tidigare forskning om samverkan visar att samarbete innefattar problem och konflikter. Syftet med denna studie är att istället beskriva mer framgångsrik samverkan även om denna utspelas under kortare interaktionsfrekvenser. I boken diskuteras forskning som analyserat framgångsfaktorer men framförallt analyseras ett eget empiriskt material med fokus på hur och när aktörerna inom ungdomsvården framsPrevious collaboration research shows that problems and conflicts sometimes arise as a part of collaboration. This book analyzes successful cooperation unfolding during shorter interaction sequences. In this study I endeavour to describe the contributing factors that are necessary to achieve the phenomenon of a successful collaboration. I do this partially with help from studies published in previ
Shortly before Christmas 2012, in a Beijing flea market and at a price, I was offered a cache of more than two thousand moth-eaten surveillance (“stake-out”) logs from the early 1950s emanating with the Bureau of Public Security in the city of Harbin, Manchuria. Unable to figure out what to do with them, I turned the offer down. Only later did it dawn on the historian in me that the logs just migh
Popular Abstract in Swedish De senaste årens framsteg inom bioteknologin har medfört att det utvecklas allt fler proteinbaserade läkemedel. Detta innebär att vi har fått bättre mediciner mot allvarliga sjukdomar, men tyvärr måste proteiner nästan alltid tas med spruta, och ofta krävs långa behandlingar med dagliga injektioner. Det finns även andra grupper av läkemedelssubstanser som ökar i omfattnControlled-release formulations reduce the frequency of injections and better maintain plasma concentrations within the therapeutic window. Poly(D,L-lactide-co-glycolide) (PLG) is currently the most frequently used biodegradable polymer for this application. In order to be able to control the release rate, it is vital to know the underlying release mechanisms. A novel method for measuring the diff
This thesis consists of two parts which deal with different subjects. In the first part we study certain aspects of the representation theory of affine Kac-Moody Lie algebras and related structures. We notice that for any positive integer k, the set of (1,2)-specialized characters of the level k standard A11-modules is the same as the set of rescaled graded dime
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances from the NH band at 336 nm in 35 extremely metal-poor halo giants, with carbon and oxygen abundances from Cayrel et al. (2004, A&A, 416, 1117), using high-quality ESO VLT/UVES spectra (30 of our 35 stars are in the range -4.1 <[Fe/H] < -2.7 and 22 stars have [Fe/H] < -3.0). N abundance
The extraction procedure for analysis of the raffinose family oligosaccharides (RFOs) in blanched leguminous vine peas was optimized. For this purpose, 25 pea samples from different cultivars and of different maturity were chosen at random. The effect of blanching was also studied in four cultivars. The yield of oligosaccharides was almost double on average when extracted with 50% ethanol as compa
Fluorescence recovery after photobleaching, FRAP, has been an established technique of quantifying the mobility of molecular species in cells and cell membranes for more than 30 years. However, under non-ideal experimental conditions the current methods of analysis still suffer from occasional problems, for example, when the signal to noise ratio is low, when there are temporal fluctuations in the

Antalet företagsförvärv har ökat markant på den svenska marknaden de senaste åren. Med anledning av att företagsförvärv är förknippade med stora risker kan det leda till tvister parterna emellan. Det är därför av vikt att en due diligence görs för att kunna avgöra riskfördelningen när det gäller särskilda förutsättningar som är av betydelse för rättsförhållandet mellan det köpande och säljande bolIn recent years the amount of corporate acquisitions has increased significantly on the Swedish market. Due to the fact that corporate acquisitions are associated with risks, conflicts between the parties can arise. Due diligence must hence be conducted in order to determine the distribution of risks regarding the legal relationship between the buying and selling company. An essential part of the
This report is about glazed balconies and intends to answer following questions: • Does glazed balconies have a “grey area” – i.e. is it free for interpretation? • Are better definitions for glazed balconies and its aspects needed? • Can our research expand the possibilities with glazed balconies from an aesthetic and practical view? The report will be processing different types of definitions and
