Health Status at Long-Term Follow-Up in Patients Treated for Extremity Localized Ewing Sarcoma or Osteosarcoma: A Scandinavian Sarcoma Group Study

Background. The purpose of this study was to evaluate late effects and symptom complaints in long-term survivors (>5 years) of Extremity Bone Sarcoma (EBS Survivors). The results were compared with findings in age- and gender-matched individuals from the general Population (NORMs). Patients and Methods. Among 155 EBS Survivors approached, 133 (86%) were included, and 110 of them (83%) attended an

Electrocardiographic characteristics of fibrillatory waves in new-onset atrial fibrillation

Aims In atrial. fibrillation (AF), fibrillatory waves of surface electrocardiograms (ECG) vary among patients with respect to waveform and repetition rate. The purpose of this study was to (i) explore clinical determinants of new-onset AF and (ii) determine prognostic significance to predict initial treatment outcome of electrocardiographic fibrillatory wave characteristics in new-onset AF Methods

Soot visualisation by use of laser-induced soot vapourisation in combination with polarisation spectroscopy

A novel approach to the visualisation of soot is presented. It relies on a combination of laser-induced soot vapourisation and consecutive polarisation spectroscopy. Upon soot vapourisation, molecular fragments (for example, C-2) emerge, and may serve as effective tracers for soot. In this study we demonstrate that saturated polarisation spectroscopy on photoinduced C-2 can be exploited for soot d

Consumption patterns, complexity and enrichment in aquatic food chains

The interactions between consumers and prey, and their impact on biomass distribution among trophic levels, are central issues in both empirical and theoretical ecology. In a long-term experiment, where all organisms, including the top predator, were allowed to respond to environmental conditions by reproduction, we tested predictions from `prey-dependent' and `ratio-dependent' models. Prey-depend

A demographic comparison of two Nordic populations of Greylag Geese Anser anser

Greylag Geese Anser anser have been neck-banded on an annual basis in Scania, southern Sweden since 1984 and in Norway since 1986 as part of a Nordic Greylag project. This has yielded a large database of resightings, which we used here to estimate and compare survival rates between the two populations by means of mark-recapture models. Estimated adult survival was sex-dependent in the Scanian popu

Detection of acute ischemia from the EASI-derived 12-lead electrocardiogram and from the 12-lead electrocardiogram acquired in clinical practice

ST-segment measurements in the standard 12-lead electrocardiogram (ECG) of patients with acute coronary syndromes are crucial for these patients' management. Our objective was to determine whether the 12-lead ECG derived from the 3-lead EASI system can attain a level of diagnostic performance similar to that of the Mason-Likar (ML) 12-lead ECG acquired in clinical practice (CP) by paramedics and e

Arylsulfatase B is present in crystalloid-containing granules of human eosinophil granulocytes

Eosinophil granulocytes are characterized by large crystalloid-containing granules whose major contents of highly cationic proteins may play a role in allergic reactions and parasitic infections. Human eosinophils are also rich in arylsulfatase B whose enzymatic activity is localized to a population of small type cytoplasmic granules and used as a marker for such organelles. We utilized immunoelec

The effect of dominance on food hoarding: A game theoretical model

Many food hoarding animals live in small groups structured by rank. The presence of conspecifics in the hoarding area increases the risk of losing stored supplies. The possibility of stealing from others depends on a forager's rank in the group. Highly ranked individuals can steal from subordinates and also protect their own caches. Since storing incurs both costs and benefits, the optimal hoardin

Oxygen uptake rate measurements for evaluation of ozonation of municipal wastewater

Ozonation has become more frequently used as oxidant to reduce chemical oxygen demand (COD) and toxic substances in wastewater originating from different industrial processes. An ozonation pilot plant followed by two parallel biological filters are used to investigate the possibility to reduce the high concentration of refractory COD in the effluent from a municipal wastewater treatment plant, par

PKC and MAPK signalling pathways regulate vascular endothelin receptor expression

Up-regulation of vascular endothelin type A (ET(A)) and type B (ET(B)) receptors are implicated in the pathogenesis of cardiovascular disease. Culture of arteries has been shown to induce similar receptor alterations and has therefore been suggested as a suitable method for in detail delineation of the regulation of endothelin receptors. We hypothesize that protein kinase C (PKC) and mitogen-activ

Vision in the deep sea

The deep sea is the largest habitat on earth. Its three great faunal environments - the twilight mesopelagic zone, the dark bathypelagic zone and the vast flat expanses of the benthic habitat- are home to a rich fauna of vertebrates and invertebrates. In the mesopelagic zone (150-1000 in), the down-welling daylight creates an extended scene that becomes increasingly dimmer and bluer with depth. Th

Polybrominated diphenyl ether exposure to electronics recycling workers - a follow up study

Workers at an electronics recycling plant have previously been shown to have elevated serum levels of polybrominated diphenyl ethers (PBDEs) compared to referents without occupational PBDE exposure. Subsequent structural changes and industrial hygiene measures at the plant were applied to improve the work environment. The present study aims to assess the impact of these work environment changes on

Bridge splitting of trans-[PtCl2(C2H4)](2) by ethene using a simple combined NMR-UV/vis cell: Crystal and molecular structure of cis-[PtCl2(C2H4)(2)]

Bridge splitting of trans- [PtCl2(C2H4)](2) by C2H4 in chloroform yields trans-[PtCl2(C2H4)(2)] which slowly isomerises to cis[PtCl2(C2H4)(2)] (crystal structure reported); the bridge-splitting equilibrium constant was determined as 6.8 +/- 0.6 mol(-1) dm(3) by the use of a combined NMR tube/spectrophotometric cell, enabling NMR and UV/vis measurements on the same closed system.

Diversification of unicellular eukaryotes: cryptomonad colonizations of marine and fresh waters inferred from revised 18S rRNA phylogeny

The cryptomonads is a well-defined lineage of unicellular eukaryotes, composed of several marine and freshwater groups. However, the evolutionary relationships among these groups are unclear due to conflicting inferences between morphological and molecular phylogenies. Here, we have inferred the evolutionary relationships among marine and freshwater species in order to better understand the import

X-ray absorption and resonant Auger spectroscopy of O(2) in the vicinity of the O 1s-->sigma(*) resonance: Experiment and theory.

We report on an experimental and theoretical investigation of x-ray absorption and resonant Auger electron spectra of gas phase O(2) recorded in the vicinity of the O 1s-->sigma(*) excitation region. Our investigation shows that core excitation takes place in a region with multiple crossings of potential energy curves of the excited states. We find a complete breakdown of the diabatic picture for

Abstract in German Die Bestimmung des prostataspezifischen Antigens (PSA) ist in der Frühdiagnostik des Prostatakarzinoms nach wie vor von zentraler Bedeutung. Ein ungelöstes Problem ist jedoch die geringe Spezifität dieses organ- aber nicht karzinomspezifischen Serummarkers, die bei einer hohen Anzahl von Patienten zu weiterer, dann invasiver Diagnostik führt, ohne dass ein Prostatakarzinom gefunDetection of prostate-specific antigen remains the mainstay in the early detection of prostate cancer. A problem yet unsolved is the lack of specificity of this organ- but not cancer-specific marker, which generates subsequent, invasive procedures in a high number of patients without detecting prostate cancer. While the separate detection of free PSA and the ratio of free to total PSA has signific
