Spectral Doppler ultrasound imaging typically consists of a spectrogram, showing the velocity distribution of the blood, and a brightness (B-) mode image allowing the operator to navigate. It is desirable to have both high spectral and velocity resolution, so that details in the blood flow can be traced, as well as a high B-mode frame rate to allow for tracking of movements and to adjust the posit

Background When acute coronary syndrome (ACS) cannot be ruled out, emergency department (ED) patients with chest pain are admitted for in-hospital observation because of the risk of complications such as arrhythmia and acute heart failure. A study was undertaken to compare the ability of three risk prediction models to identify patients at a very low risk of complications. Methods 559 consecutive

The past decade has seen a vast increase in empirical research investigating associations between social capital and health outcomes. Literature reviews reveal 'generalized trust' and 'social participation' to be the most robust of the commonly used social capital proxies, both showing positive association with health outcomes. However, this association could be confounded by unmeasured factors, s

A measurement of the production cross section of top quark pairs (t (t) over bar) in proton-proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider is reported. Candidate events are selected in the dilepton topology with large missing transverse energy and at least two jets. Using a data sample corresponding to an integrated luminosity of

Malignant fibrous histiocytoma (MFH) and fibrosarcoma (FS) of bone are rare malignant tumours and contentious entities. Sixty seven cases labelled as bone MFH (57) and bone FS (10) were retrieved from five bone tumour referral centres and reviewed to determine whether recent advances allowed for reclassification and identification of histological subgroups with distinct clinical behaviour. A panel

Contributions of vibrationrotation interaction to line intensities of pure rotational coherent anti-Stokes Raman scattering (CARS) of oxygen are here considered in the perspective of what was remarked by us recently for nitrogen. The interaction is conventionally evaluated by means of the so-called HermanWallis (HW) factor, the need of which is conceptually clear but the theoretical expression is

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerdiagnosen hos kvinnor, och under år 2011 fick över 8000 svenska kvinnor denna diagnos. Termen bröstcancer är egentligen ett samlingsnamn för alla de olika typer av cancer som kan uppstå i bröstet. En del typer av bröstcancer har en bra prognos medan andra trots aggressiv behandling alltjämt har en dålig prognos. Cancer är en sjukdom dBreast cancer is a heterogenous disease which can be divided in subgroups of distinct biology with disparate prognosis and response to treatment. The overall aim of this thesis was to delineate subgroup specific behaviour in breast cancer cells with focus on proliferation, migration and stem-like cell activity. In addition, we have studied the functional retinoblastoma tumour suppressor (RB) prote

Wilms Tumor suppressor protein (WT1) is a transcription factor that is involved in a variety of developmental functions during organ development. It is also implicated in the pathology of several different cancer forms. The protein contains four C(2)H(2)-type zinc fingers and it specifically binds GC-rich sequences in the promoter regions of its target genes, which are either up or down regulated.

This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of

Tracking migratory movement of small animals with variable migration patterns is difficult with standard mark-recapture methods or genetic analysis. We used stable hydrogen isotope (delta D) measurements of wings from European red admirals Vanessa atalanta to study several aspects of this species' migration. In the central part of southern Europe we found large differences in delta D values betwee

Popular Abstract in Swedish Det görs en rad försök till demokratisk förnyelse ute i kommunerna. I denna avhandling är det min ambition att analysera ett sådant försök; medborgarutskotten i Helsingborg. De frågeställningar avhandlingen behandlar är 1) vad ligger bakom samtalets betoning i medborgarutskottens deltagardemokratiska aktiviteter? 2) Hur positioneras kommuninvånare som medborgare då medThis is a study of civic communication in a municipal setting. In the south Swedish municipality of Helsingborg operated Civic Committees between 2003 and 2006. The Civic Committees organized different kinds of activities together with the citizens out in the different neighbourhoods of the municipality, such as open meetings, neighbourhood walks, workshops for the future and meetings with specifi

The problems of allocation of scarce resources and priority setting in health care have so far not been much studied in the context of stem cell-based therapeutic applications. If and when competitive cost-effective stem cell-based therapies are available, the problem of priority setting - to whom should stem cell-based therapies be offered and on what grounds - is discussed in this article using

Atypical hemolytic uremic syndrome (aHUS) emerged during the last decade as a disease largely of complement dysregulation. This advance facilitated the development of novel, rational treatment options targeting terminal complement activation, e.g., using an anti-C5 antibody (eculizumab). We review treatment and patient management issues related to this therapeutic approach. We present consensus cl

The decay chain of Fm-246 has been investigated employing the SHIP separator at GSI Darmstadt. The Fm-246 nuclei were produced via the Ar-40(Pb-208, 2n)Fm-246 fusion-evaporation reaction. Improved values of the half-life, T-1/2 = 1.54(4) s, and of the spontaneous fission branching ratio, b(SF) = 0.068(6), of Fm-246 were obtained. The beta(+)/electron capture branching ratio, b(EC) = 0.39(3), of Cf

Background: Earlier analyses within the EPIC study showed that dietary fibre intake was inversely associated with colorectal cancer risk, but results from some large cohort studies do not support this finding. We explored whether the association remained after longer follow-up with a near threefold increase in colorectal cancer cases, and if the association varied by gender and tumour location. Me

OBJECTIVES: Between 1984 and 1996, Sweden experienced an "epidemic" of clinical celiac disease in children

The dinuclear title compound, [FePtCl2(C17H14P)(C23H23NO3P)]x1.25CH2Cl2, has a slightly distorted cis-PtCl2P2 square-planar geometry around the Pt atom, and the ferrocenylphosphine ligands are staggered at an angle of 29.4 (2) deg. about Pt. In the crystal structure, the complex forms centrosymmetric dimers via two strong intermolecular O—H-O bonds resulting in R22(8) rings. A weak intramolecular

The K 2p photoionization and subsequent LMM Auger decay have been studied for molecular gas-phase KCl, KBr and KI. The detected manifold spectral structure of the Auger electron spectrum of KCl has been interpreted to originate from strong molecular field effects. This indicates that Auger decay on potassium side of originally very ionic molecules creates inner-shell hole states with a strong mole
