In this study we investigate the effect of programmed cross-flows on the error in the hydrodynamic radii (r(h)) determination with asymmetrical flow field-flow fractionation (AsFlFFF). Three different standard polystyrene particles (nominal radii of 30 and 40 and 50nm) are fractionated with exponentially and linearly decaying cross-flows with different decay rates. Hydrodynamic radii are calculate

Long term effects after peptic ulcer surgery still exert an influence on some patient groups. Partial gastrectomy increases the risk of gastric carcinoma more than 20 years after surgery and enterogastric reflux is regarded as the main ethiological factor. Partial gastrectomy also gives increased risk of other malignancies as well as smoking related disease. Parietal cell vagotomy (PCV) is conside

The NICE trial was designed to evaluate the possible benefits of adding epidermal growth factor receptor targeted therapy to neoadjuvant chemotherapy in patients with estrogen receptor alpha (ER) negative and operable breast cancer. Preclinical data have suggested that signalling through the ErbB receptors or downstream effectors may repress ER expression. Here the authors investigated whether gef

A minor novel 1,7-naphthyridine alkaloid with an unprecedented skeleton, named anisopusine (1), was isolated from the CH2Cl2 soluble materials of an acetone extract of the bark of Anisopus mannii (Asclepiadaceae) together with four known compounds 5 alpha-hydroxy-lup-20(29)-en-3 beta-yl eicosanoate (2), [6]-gingerdione (3), [6]-dehydrogingerdione (4), and ferulic acid (5). Their structures were de

Popular Abstract in Swedish Dagens vårdsystem står inför många stora utmaningar. Många av dem är relaterade till komplexa vårdbehov hos den allt större andelen sköra äldre personer. Denna andel ökar samtidigt som många vårdorganisationer har krav på sig att minska kostnaderna. Dessa äldre personer har ofta flera sjukdomar samtidigt och de har vanligtvis kontakter med många olika vårdgivare, på fleThe overall aim of this thesis was to investigate healthcare utilisation patterns and to explore the effects of a case management intervention for frail older people on healthcare utilisation and costs in relation to utility. A further aim was to explore the older people’s and case managers’ experiences of the intervention. Study I was a quantitative study comprising ten age cohorts aged between 6

Global gene expression profiles, consisting mainly of genes associated with proliferation, have been shown to subdivide histological grade 2 breast cancers into groups with different prognosis. We raised the question whether this subdivision could be done using a single proliferation marker, cyclin A. Furthermore, we combined cyclin A (CA), histological grade (G), and estrogen receptor-ER (E) into

Objectives To describe the clinical and ultrasound features of fibroma and fibrothecoma of the ovary. Methods Sixty-eight women with a histological diagnosis of fibroma or fibrothecoma of the ovary who had undergone a preoperative ultrasound examination between 1999 and 2007 were identified from the databases of four ultrasound centers. The tumors were characterized on the basis of ultrasound imag

The PHENIX experiment at RHIC has measured the centrality dependence of the direct photon yield from Au + Au collisions at root s(NN) = 200 GeV down to pT = 0.4 GeV/c. Photons are detected via photon conversions to e(+)e(-) pairs and an improved technique is applied that minimizes the systematic uncertainties that usually limit direct photon measurements, in particular at low pT. We find an excess

Background: In the course of the last four decades, the profession of physiotherapy has progressively expanded its scope of responsibility and its focus on professional autonomy and evidence-based clinical practice. To preserve professional autonomy, it is crucial for the physiotherapy profession to meet society's expectations and demands of professional competence as well as ethical competence. S

Caspase 8 initiates apoptosis downstream of TNF death receptors by undergoing autocleavage and processing the executioner caspase 3 (ref. 1). However, the dominant function of caspase 8 is to transmit a pro-survival signal that suppresses programmed necrosis (or necroptosis) mediated by RIPK1 and RIPK3 (refs 2-6) during embryogenesis and haematopoiesis(7-9). Suppression of necrotic cell death by c

There is no unified view as to what partnering relationships are in the construction industry. The purpose of this paper is to examine the literature in order to identify the main assumptions about partnering relationships in construction research and practice. The literature is compared to the Construction Industry Institute's (CII, 1991) frequently cited definition of partnering as a long-term c

Group 1 grass pollen allergens are a major cause of allergic disease. Specific immunotherapy involving controlled administration of allergens can be used as a disease-modifying treatment for such disease. Recombinant allergen variants with reduced IgE binding capacity may be used as component in such vaccines, as they may induce fewer treatment side effects than materials currently in use. A mutat

I den här artikeln argumenteras för att etnologin har viktig forskningsuppgift i att studera Sanningens rörlighet i termer av kulturella processer, närmare bestämt att besvara frågorna hur, var, när, vem och varför. För att föra det ser författaren ett fruktbart analytiskt angreppssätt i att kombinera diskursteoretiska begrepp och sociologiska och hämtar inspiration från såväl Laclau och Mouffe oc

Objective: The aim of this study was to describe and assess changes in participants' experiences of everyday occupations after nature-based vocational rehabilitation (NBVR), to assess changes regarding symptoms of severe stress and the rate of return to work and possible association with experiencing the occupational value of everyday occupations. Methods: The NBVR was carried out by a transdiscip

Arterial stiffness is an independent risk factor for cardiovascular morbidity and can be assessed by applanation tonometry by measuring pulse wave velocity (PWV) and augmentation index (AIX) by pressure pulse wave analysis (PWA). As an inexpensive and operator independent alternative, photoelectric plethysmography (PPG) has been introduced with analysis of the digital volume pulse wave (DPA) and i

Popular Abstract in Swedish Diabetes mellitus är en endokrin sjukdom. Hos friska individer producerar beta och alpha cellerna i bukspottkörteln insulin och glukagon, de viktigaste hormonerna för att reglera blodglukos¬koncentrationen. Insulin utsöndras som svar på förhöjda blodglukosnivåer. Hormonet minskar glukosproduktion från levern och ökar glukosupptaget samt dess användning och lagring i fetType 2 Diabetes (T2D) is a multifactorial disease, which has made it difficult to resolve its pathophysiology. We investigated processes that could contribute to the development of T2D. In addition to well-known hallmarks of the disease, such as defective insulin secretion, insulin resistance and perturbed glucagon secretion, we aimed to find a possible role for CLOCK genes in the pathogenesis of

The semantic formalism reference attribute grammars (RAGs) allows graphs to be superimposed on abstract syntax trees. This paper investigates how RAGs can be used to model visual languages, with a case study of a control language that also has a textual syntax. The language contains blocks on which a total execution order is defined based on connections and layout information. One strength of RAGs
