Isozyme electrophoresis was used to study the morphologically similar sister speciesSphagnum rubellum andS. capillifolium from a sample of 1313 plants representing 37 populations from Scandinavia, Great Britain and S Germany. The mean pairwise genetic identities (I) among conspecific populations were 0.976 forS. rubellum and 0.969 forS. capillifolium, versus 0.627 between populations of the two sp
Background: In acquired heart disease, brain natriuretic peptide (BNP) and N-Teminal pro-brain natriuretic peptide (NT-proBNP) are increasingly used as diagnostic and prognostic markers. In adult Congenital heart disease, the abnormal anatomy and physiology complicate assessment of cardiac function. We Studied the clinical correlates of measurement of natriuretic peptides (NP) in adults with a rig
Insulin resistance may be a risk factor for breast cancer, possibly through increased levels of oestrogens or insulin-like growth factor I. Insulin resistance has been associated with obesity, hypertension, dyslipidaemia and impaired glucose tolerance. We studied the relation of these factors to breast cancer risk in a prospective cohort study of 9738 women. Menopausal status was defined a priori,
To analyze the role of the classical and alternative pathways of complement activation in the effector phase of arthritis, we have induced arthritis in C3- and factor B (FB)-deficient (C3(-/-) and FB-/-) DBA/1J mice using well-defined monoclonal IgG2b and IgG2a antibodies to type II collagen. In control DBA/1J mice, severe swelling of the joints, destruction of cartilage and erosion of bone develo
The southern section of the Mylonite Zone (MZ) is a major lithotectonic terrane boundary in the SW Baltic Shield. It separates the parautochthonous Eastern Segment of the Sveconorwegian orogen from the allochthonous Western Segment. Complex zircons in migmatised and banded orthogneisses along the southern MZ were investigated by ion microprobe analyses guided by backscattered electron imaging to d
A hidden Markov regime is a Markov process that governs the time or space dependent distributions of an observed stochastic process. We propose a recursive algorithm for parameter estimation in a switching autoregressive process governed by a hidden Markov chain. A common approach to the recursive estimation problem is to base the estimation on suboptimal modifications of Kalman filtering techniqu
Combined treatment with electroremediation and sulphate reducing bacteria (SRB) was tested in laboratory and pilot scale. The contaminated soil came from a chlor-alkali factory and contained about 100 mg/kg Hg. Iodide/iodine complexing agent was used to mobilize mercury. Mercury iodide complexes were moved to the anode solution using an electric field. The anode solution was then mixed with hydrog
The copper coordination geometry in the blue copper proteins plastocyanin, nitrite reductase, cucumber basic protein, and azurin has been studied by combined density functional (B3LYP) and molecular mechanical methods. Compared to quantum chemical vacuum calculations, a significant improvement of the geometry is seen (toward the experimental structures) not only for the dihedral angles of the liga
There is currently no effective vaccine for Neisseria meningitidis (Nm) serogroup B. Generation of optimal immune responses to meningococci could be achieved by targeting meningococcal antigens to human dendritic cells (DCs). Recent studies have shown that diverse DC responses and subsequent generation of protective immunity can be observed if the microbes are viable or killed. This is important b
Background and purpose: The purpose of this work was a comparison of realistic IMRT plans based on the same CT-image data set and a common predefined set of dose objectives for the planning target volume and the organs at risk. This work was part of the larger European QUASIMODO IMRT verification project. Materials and methods: Eleven IMRT. plans were produced by nine different European groups, ea
We report on the development of a bi-layer bi-enzyme biosensor architecture using different peroxidases and alcohol oxidase from Hansenula polymorpha C-105 as biological recognition elements. The sensor architecture comprises a first layer containing either horseradish peroxidase or royal palm tree peroxidase crosslinked with an Osmium complex-modified redox hydrogel. On top, a second layer was fo
A survey of the use of Os-187 satellite subspectra in H-1 and P-31{H-1} spectra of triosmium carbonyl clusters is reported. By varying evolution delays in HMQC spectra of [Os-3(mu-H)(2)(CO)(10)] we have selectively extracted the values for (1)J(Os,H) and (2)J(Os,H), respectively. An analysis of the principal modes of phosphine coordination in triosmium clusters demonstrates that P-31{H-1} Os-187 s
The suitability of high-Z materials as build-up caps for head-scatter measurements has been investigated. Build-up caps are often used to enable characterization of fields too small for a mini-phantom. We have studied lead and brass build-up caps with sufficiently large wall thicknesses, as compared to the range of contaminating electrons originating in the accelerator head, and compared them with
A group of investigators met at a Specialized Programs of Research Excellence Workshop to discuss key issues in the translation of biomarker discovery to the development of useful laboratory tests for cancer care. Development and approval of several new markers and technologies have provided informative examples that include more specific markers for prostate cancer, more sensitive tests for ovari
Jurassic strata are extensively distributed in offshore areas of Scandinavia, but onshore exposures are mostly restricted to southern Sweden (Skane), the Danish island of Bornholm, East Greenland, northern Norway (Andoya) and Svalbard. The latest Triassic and Jurassic saw active tectonism in Scandinavia associated with the break-up of Pangaea and rifting in the North Atlantic region and the North
We investigated the quality of life (QoL) of newly diagnosed persons with cancer aged 65 years at baseline and 3 months after, in relation to age, contact with the healthcare system, activities of daily living, hope, social network and support using the European Organization for Research and Treatment of Cancer QLQ-C30, Katz ADL, Nowotny's Hope Scale, and the Interview Schedule for Social Interact
We propose new applications of three-terminal ballistic junctions (TBJs) in nanoelectronics. It is found that for a TBJ with one of its three branch contacts, say the right branch contact, being grounded, the output voltage, V-c, from the central branch as a function of the voltage, Vl, applied to the left branch shows a diode characteristic: V-c approximately follows Vl linearly when Vl is negati
