A novel capacitance biosensor based on synthetic phytochelatins for sensitive detection of heavy metals is described. Synthetic phytochelatin (Glu-Cys)20Gly (EC20) fused to the maltose binding domain protein was expressed in Escherichia coli and purified for construction of the biosensor. The new biosensor was able to detect Hg2+, Cd2+, Pb2+, Cu2+ and Zn2+ ions in concentration range of 100 fM–10
Background: The appropriate management of women with minor cytologic lesions in their cervix is unclear. We performed a meta-analysis to assess the accuracy of human papillomavirus (HPV) DNA testing as an alternative to repeat cytology in women who had equivocal results on a previous Pap smear. Methods: Data were extracted from articles published between 1992 and 2002 that contained results of vir
The objectives of the project were threefold: to utilize the proposed ISO tests to derive basic flammability characteristics which could rationally bc used as classification criteria: to generate a full-scale fire test standard: and finally, to mathematically correlate small-scale test data and the full-scale fire process. For this purpose 13 materials were tested in eight small-scale tests in the
Based on morphology, a cladistic analysis of the Neotropical family Quiinaceae (Malpighiales) was performed to generate a hypothesis of the phylogenetic relationships within the family. The monotypic Medusagynaceae and four species of Ochnaceae were used as outgroup. Using equal weights, the Quiinaceae find strong jackknife support and all genera, apart from Lacunaria. are monophyletic. Lacunaria
Neutral Higgs bosons of the Standard Model (SM) and the Minimal Supersymmetric Standard Model (MSSM) were searched for in the data collected in 1999 by the DELPHI experiment at centre-of-mass energies between 191.6 and 201.7 GeV with a total integrated luminosity of 228 pb(-1). These analyses, in combination with our results at lower energies, set 95% confidence level lower mass bounds on the Stan
The present study investigated differences in judgments of one's own and others' knowledge (the own-other difference). Consistent with the below-average effect (e.g., Kruger, 1999), our main results showed that the participants gave lower knowledge ratings of their own extent of knowledge than of another person's extent of knowledge (Experiment 1). Furthermore, lower and more realistic judgments w
Background and aims: Activation of pancreatic proteases is considered to be a crucial event in the early phase of acute pancreatitis but the cause of this activation is not known. Most cases of acute pancreatitis can be attributed to either gallstone disease or alcohol abuse. However, little is known about other risk factors. The aim of this thesis is to investigate the mechanisms involved in the
The plant respiratory chain contains a complex setup of non-energy conserving NAD(P)H dehydrogenases, the physiological consequences of which are highly unclear. An expression construct for the potato (Solanum tuberosum L., cv. Desiree) ndb1 gene, a homologue of bacterial and fungal type II NAD(P)H dehydrogenases, was introduced into Nicotiana sylvestris. Transgenic lines with high transcript and
Popular Abstract in Swedish Studiet av entreprenøren er ikke et studium om en «helt på sin hvite hest», som er en ikke uvanlig kritikk av vellykkete næringsdrivende, men snarere en analyse av helt vanlige menneskers tanker, drømmer og liv. Entreprenørene er vanskelige å finne for de er sjeldent forekommende i befolkningen. De er viktige fordi de utfører innovasjoner, som innebærer at man blir i stThis dissertation, which is an analysis of the entrepreneur at the micro level, supplements and underpins the understanding and use of the entrepreneur as an agent of social change in the analysis of economic change at the macro level. The aim of the thesis is firstly to seek out and identify businessmen of our time who claim to be innovative, and secondly to un-dertake a qualitative study and ana
Purpose: Good to excellent clinical results have been shown in the initial studies on osseointegrated metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint implants that consist of a flexible silicone spacer connected to osseointegrated titanium fixtures. A high fracture rate of the silicone spacer, however, has been reported, diminishing the value of this implant system. The purpose
Conditions for predicting the effects of intervention with certainty are derived. An outside observer studies sequences of actions from a two-person repeated prisoners' dilemma. The sequences are generated by finite automata, which are optimal at each stage of the game and also minimize the number of states. An intervention is a change of action for one of the players and a prediction is a stateme
Objective Arterial pulse contour analysis is gaining widespread acceptance as a monitor of continuous cardiac output (CO). While this type of CO measurement is thought to provide acceptable continuous measurements, only a few studies have tested its accuracy and repeatability under unstable hemodynamic conditions. We compared continuous CO measurement using the pulse contour method (PCCO) before a
Colonized bank voles (Clethrionomys glareolus) originating from Sweden developed type 1 diabetes. Animals became polydipsic, glucosuric, and hyperglycemic and gradually developed a lethal ketoacidosis. Pancreas in animals with end-stage disease showed total destruction of islet cells. Interestingly, also a high proportion of wild bank voles in cyclic populations that were trapped at (or close to)
Media coverage is often held responsible for the erosion of public support for European integration. At the same time, a well-functioning political journalism is also held up as an important requirement for EU democracy. Set against this background of confl icting perceptions of the media, this report analyzes political journalism’s critical performance in the realm of EU constitutionmaking. The r
Thiazolidinediones are antidiabetic agents that decrease insulin resistance. Emerging evidence indicates that they present beneficial effects for the vasculature beyond glycemic control. The aim of this open-label observational study was to determine the effect of the thiazolidinedione rosiglitazone on novel cardiovascular risk factors, namely, lipoprotein(a) [Lp(a)], C-reactive protein (CRP), hom
