Flow-injection assay of the pathogenic bacteria using lectin-based quartz crystal microbalance biosensor
A novel flow-injection assay of the pathogenic enterobacteria using novel lectin-based quartz crystal microbalance (QCM) biosensor has been proposed. The biosensing part of the analytical device contained the lectins - Concanavalin A, lectins from Ulex europeus, Maackia amurensis, Lens culinaris, wheat germ agglutinin - immobilized on the gold surface of quartz crystal electrode which served as a
Transvaginal ultrasound assessment of myometrial and cervical stromal invasion in women with endometrial cancer: interobserver reproducibility among ultrasound experts and gynecologists
Objectives To assess interobserver reproducibility among ultrasound experts and gynecologists in the prediction by transvaginal ultrasound of deep myometrial and cervical stromal invasion in women with endometrial cancer. Methods Sonographic videoclips of the uterine corpus and cervix of 53 women with endometrial cancer, examined preoperatively by the same ultrasound expert, were integrated into a
Nonadiabatic Van der Pol oscillations in molecular transport
The force exerted by the electrons on the nuclei of a current-carrying molecular junction can be manipulated to engineer nanoscale mechanical systems. In the adiabatic regime a peculiarity of these forces is negative friction, responsible for Van der Pol oscillations of the nuclear coordinates. In this work we study the robustness of the Van der Pol oscillations against high-frequency sources. For
Evacuation in Underground Rail Transportation Systems: A Summary of the Findings of the METRO Project
The paper presents the major findings from the three evacuation experiments being part of the Swedish METRO research project. In the evacuation experiments; the small, medium and full-scale experiments, investigations were carried out with the purpose to study how train passengers safely can be evacuated in case of a fire emergency. In addition to determine flow rates, the walking velocity and wal
A Multitechnique Study of Structure and Dynamics of Polyfluorene Cast Films and the Influence on Their Photoluminescence
This article describes the microstructure and dynamics in the solid state of polyfluorene-based polymers, poly(9,9-dioctylfluorenyl-2,7-diyl) (PFO), a semicrystalline polymer, and poly[(9,9-dioctyl-2,7-divinylene-fluorenylene)-alt-co-{2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene vinylene}, a copolymer with mesomorphic phase properties. These structures were determined by wide-angle X-ray scatterin
Comparison of three assays for the detection of GAD65Ab-specific anti-idiotypic antibodies
Anti-idiotypic antibodies (anti-Id) to autoantibodies are present in several autoimmune diseases and are hypothesized to have regulatory function. Recently we reported the presence of anti-Id to a major type 1 diabetes-associated autoantibody (CAD65Ab) in sera of healthy individuals. Our current assay for the detection of GAD65Ab-specific anti-Id requires the initial removal of anti-Id from the se
Computer-assisted surgery in children
Although positive in terms of patient trauma and recovery time, minimally invasive surgery has several technical drawbacks compared with open surgery. The new da Vinci® Surgical System from Intuitive Surgical® offers technical innovations aiming at overcoming these drawbacks and at improving the surgeon’s operating skills, such as the improved 3-D vision, tremor reduction and flexible instruments
Characterization of White Layer Generated when Turning Aged Inconel 718
Abstract in UndeterminedWhite layer formation is considered as a part of minimum array of parameters characterizing surface integrity of the machined product. The paper is aimed on identification and characterization of white layer generated when finish turning aged Inconel 718 with Al2O3-SiCw ceramic tools under different cutting conditions, tool wear and coolant application. As expected intensit
Agrarian Populism in Colonial and Postcolonial Malawi
This article analyses continuity and change of the agrarian doctrine in colonial and postcolonial Malawi. It engages in a classic debate about images and polices concerning African farming. The article argues that the agrarian doctrine must be related to the broader notion of agrarian populism, more specifically to Chayanov's notion of the logic of the peasant family farm. Employing this broader a
VarioML framework for comprehensive variation data representation and exchange
Background: Sharing of data about variation and the associated phenotypes is a critical need, yet variant information can be arbitrarily complex, making a single standard vocabulary elusive and re-formatting difficult. Complex standards have proven too time-consuming to implement. Results: The GEN2PHEN project addressed these difficulties by developing a comprehensive data model for capturing biom
Cell cycle perspectives on breast cancer cell behaviour
Uncontrolled proliferation and the capacity to infiltrate surrounding tissues are two important characteristics of aggressive tumour cells. Previous observations in both colorectal cancer and basal cell carcinoma indicated that infiltrative tumour cell behaviour might be counteracted by a high proliferative activity, suggesting a coordination of these two activities at the cellular level. Here we
Ceaușescu och litteraturen. Mellan antisovjetism och personkult
The goal of this article is to examine what role literature played for Nicolae Ceaușescu, Romania's political leader between 1965 and 1989. I focus on the period between 1968 and 1974, when the basis was laid for a cultural policy which was to be applied until the end of Ceaușescu's reign in 1989. Such studies are easier to conduct today, when the archives of the Romanian Communist Party have been
Photoemission evidence for crossover from Peierls-like to Mott-like transition in highly strained VO2
We present a spectroscopic study that reveals that the metal-insulator transition of strained VO2 thin films may be driven towards a purely electronic transition, which does not rely on the Peierls dimerization, by the application of mechanical strain. Comparison with a moderately strained system, which does involve the lattice, demonstrates the crossover from Peierls- to Mott-like transitions.
Dietary intakes and food sources of phytoestrogens in the European Prospective Investigation into Cancer and Nutrition (EPIC) 24-hour dietary recall cohort
BACKGROUND/OBJECTIVES: Phytoestrogens are estradiol-like natural compounds found in plants that have been associated with protective effects against chronic diseases, including some cancers, cardiovascular diseases and osteoporosis. The purpose of this study was to estimate the dietary intake of phytoestrogens, identify their food sources and their association with lifestyle factors in the Europea

Genetic Markers of Insulin Sensitivity and Insulin Secretion Are Associated With Spontaneous Postnatal Growth and Response to Growth Hormone Treatment in Short SGA Children: the North European SGA Study (NESGAS)
Purpose: The wide heterogeneity in the early growth and metabolism of children born small for gestational age (SGA), both before and during GH therapy, may reflect common genetic variations related to insulin secretion or sensitivity. Method: Combined multiallele single nucleotide polymorphism scores with known associations with insulin sensitivity or insulin secretion were analyzed for their rela

Facilitating collaboration: exploring a socio-technical approach to the design of a collaboratory for Library and Information Science
The thesis explores the potential of one way of facilitating and stimulating collaboration in Library and Information Science (LIS), through a specific scientific collaboration activity: creating, sharing and reusing data collection instruments, such as interview guides, questionnaires, and observation protocols. The four studies reported in the thesis can be read as a linear narrative, each study
Use of human amelogenin in molecular encapsulation for the design of pH responsive microparticles
Background: Proteins can be used in drug delivery systems to improve pharmacological properties of an active substance. Differences in pH between tissues can be utilized in order to achieve a targeted drug release at a specific location or tissue, such as a tumor. The enamel matrix protein amelogenin has a pH dependent solubility profile and self-assemble to form aggregates at neutral pH. This cou
