Intravenous administration of antibiotics is a known risk factor for infusion phlebitis. We have previously demonstrated differences in cell toxicity for 4 antibiotics. Clinical experience indicates that antibiotics differ in their tendency to cause phlebitis. The present study was done prospectively on 550 patients with 1386 peripheral venous catheters. The incidence of phlebitis was 18.5% with a
Here we investigated whether microwaves (MWs) of Global System for Mobile Communication (GSM) induce changes in chromatin conformation in human lymphocytes. Effects of MWs were studied at different frequencies in the range of 895-915 MHz in experiments with lymphocytes from seven healthy persons. Exposure was performed in transverse electromagnetic transmission line cell (TEM-cell) using a GSM tes
Egg and clutch size variation among populations of common frogs (Rana temporaria) were studied in 14 ponds in Sweden. Also two secondary indices, clutch mass and allocation tactics (egg size3/clutch size) were studied. For all four characters there was a pond-wise correlation between the values across the two study years. All characters differed among ponds and all but allocation tactics differed
A soy protein film coating was developed and evaluated to reduce fat transfer in deep-fried foods during frying. Soy protein isolate solutions (10% SPI) with 0.05% gellan gum as plasticizer cooled after being held at 80 degrees C for 20 min provided suitable films. There was a significant fat reduction (55.12(+/-6.03)%db) between fried uncoated and coated discs of doughnut mix. The same films were
In this article I develop a framework for thinking about the research interview, and I critique dominating neopositivist and romantic views on the interview. I suggest eight metaphors that offer reconceptualizations of the interview, drawing upon recent theoretical trends on language, the subject, and discourse, and develop a reflexive theoretical framework. The article provides new ways of dealin
The aim of this study was to examine whether Multidimensional Pain Inventory (MPI) subscale score changes can be used for monitoring interdisciplinary cognitive behavioural pain rehabilitation programmes, using the Psychological General Well-Being (PGWB) index as an independent variable of rehabilitation outcome. Data from 434 consecutively referred patients disabled by chronic pain were analysed.
ABSTRACT: INTRODUCTION: We previously reported an association between tumor-specific 3-hydroxy-3-methylglutharyl-coenzyme A reductase (HMG-CoAR) expression and a good prognosis in breast cancer. Here, the predictive value of HMG-CoAR expression in relation to tamoxifen response was examined. METHODS: HMG-CoAR protein and RNA expression was analyzed in a cell line model of tamoxifen resistance usin
This study explored the associations between body fat versus daily physical activity and insulin concentrations in non-diabetic young children in a cross-sectional study of 172 children (93 boys and 79 girls) aged 8-11 years. Blood samples were analysed for serum insulin and daily physical activity was measured by accelerometers. Time spent performing vigorous activity was estimated from accelerom
Ultrasound is a reliable tool to diagnose patent ductus arteriosus in premature infants but no reliable noninvasive method exists to quantify ductal flow. The aim of this study was to quantify the size of the shunt via persistent ductus arteriosus from pixel counts in color Doppler flow images. A cotton band was placed around the ductus arteriosus of newborn lambs to adjust the magnitude of flow.
The role of VEGF in the pathogenesis of retinopathy of prematurity (ROP) has been clearly established. However, little is known about temporal changes in circulating VEGF concentrations in the preterm infant. The objective was to determine the longitudinal serum concentrations of VEGF in relation to ROP.
Approximately 8% of clear cell renal cell carcinoma cases contain regions of radically different morphology, demonstrating a mesenchymal appearance histologically resembling sarcomas. These biphasic neoplasms are called sarcomatoid clear cell renal cell carcinoma. Patients diagnosed with sarcomatoid clear cell renal cell carcinoma face a considerably worse prognosis due to an increased propensity
Objective. To study the relationship between tobacco use and pain intensity. Design. An age-stratified cross-sectional study was carried out in southern Sweden in 2005. Sample. The population study consists of 384 people, aged 18-102 years, with chronic pain. Measurement. Data collection took place by means of a postal questionnaire. Comparisons of pain intensity were made between smokers and nons
PURPOSE: The main function of erythropoietin (EPO) is to stimulate erythropoiesis. EPO receptors (EPOR) are expressed in other cell types, including tumor cells, suggesting that the EPO/EPOR pathway governs additional cellular processes besides erythropoiesis. Recombinant EPO (rhEPO) is frequently given to anemic cancer patients, although data on clinical outcome are conflicting. In an attempt to
The objective of the present paper was to provide an estimate of the benefits of on-demand and prophylaxis treatment strategies for severe haemophilia in monetary terms. Using the contingent-valuation method, which simulates a missing market by asking people about their willingness to pay (WTP), we asked a representative sample (n = 609) of the Swedish population if they would be willing to pay a
The human B1 bradykinin (BK) receptor (B1R) is more efficacious than the human B2 BK receptor (B2R) in both ligand-independent and agonist-dependent coupling to Gq/11-mediated phospholipase Cbeta activity. In fact, B1R is constitutively active, whereas B2R exhibits little if any constitutive activity. To evaluate the role of the C-terminal domain in receptor Gq/11 coupling, we constructed chimeric
Bronchoalveolar lavage was performed in 51 patients with sarcoidosis and in 21 healthy nonsmokers. The concentration of fibronectin was significantly higher (p less than 0.001) in lavage fluid from sarcoid patients (median 267 micrograms.l-1) than in that of controls (46 micrograms.l-1). Furthermore, a significantly higher concentration of fibronectin was found in patients with active disease than
