Optical responses, permeability and diol-specific reactivity of thin polyacrylamide gels containing immobilized phenylboronic acid

Thin semitransparent gels were prepared by radical copolymerization of N-acryloyl-m-aminophenylboronic acid (NAAPBA) and acrylamide (AAm) taken in molar ratios from 8:92 to 16:84, respectively, in water. The gels were characterized by the content of immobilized NAAPBA and monomer conversion. Scanning electron microscopy revealed the micrometer size pores in the dried gels. The wet gels displayed a

Serglycin Is Implicated in the Promotion of Aggressive Phenotype of Breast Cancer Cells

Serglycin is a proteoglycan expressed by some malignant cells. It promotes metastasis and protects some tumor cells from complement system attack. In the present study, we show for the first time the in situ expression of serglycin by breast cancer cells by immunohistochemistry in patients' material. Moreover, we demonstrate high expression and constitutive secretion of serglycin in the aggressive

Hydrodynamic radius determination with asymmetrical flow field-flow fractionation using decaying cross-flows. Part II. Experimental evaluation.

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

Complications to peptic ulcer and peptic ulcer surgery

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

Value of post-operative reassessment of estrogen receptor alpha expression following neoadjuvant chemotherapy with or without gefitinib for estrogen receptor negative breast cancer

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

Chemical constituents from the bark of Anisopus mannii

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

Case management for frail older people. Effects on healthcare utilisation, cost in relation to utility, and experiences of the intervention

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

Combination of the proliferation marker cyclin A, histological grade, and estrogen receptor status in a new variable with high prognostic impact in breast cancer.

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

Imaging in gynecological disease (5): clinical and ultrasound characteristics in fibroma and fibrothecoma of the ovary

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

Centrality dependence of low-momentum direct-photon production in Au plus Au collisions at root s(NN)=200 GeV

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

The perceptions of danish physiotherapists on the ethical issues related to the physiotherapist-patient relationship during the first session: a phenomenological approach

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 inhibits programmed necrosis by processing CYLD

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

Partnering relationships in construction: A literature review

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

A folded and immunogenic IgE-hyporeactive variant of the major allergen Phl p 1 produced in Escherichia coli.

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

Att analysera Sanningens rörlighet. Objektivitet, politik och fält.

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

Changes in experienced value of everyday occupations after nature-based vocational rehabilitation

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
