An ATR-FTIR spectroscopic study of the competitive adsorption between oxalate and malonate at the water-goethite interface

The competitive adsorption between oxalate and malonate at the water-goethite interface was studied as a function of pH and total ligand concentrations by means of quantitative adsorption measurements and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. The results obtained show that ATR-FTIR spectroscopy resolves the individual spectroscopic features of oxalate and

Differential Alterations in Metabolic Pattern of the Spliceosomal Uridylic Acid-Rich Small Nuclear RNAs (UsnRNAs) During Malignant Transformation of 20-Methylcholanthrene-induced Mouse CNCI-PM-20 Embryonic Fibroblasts

Differential alterations of the spliceosomal Uridylic acid rich small nuclear RNAs (UsnRNAs) (U1, U2, U4, US, and U6) are reported to be associated with cellular proliferation and development, but definitive information is scarce and also elusive. An attempt is made in this study to analyze the metabolic patterns of major spliceosomal UsnRNAs, during tumor development, in an in vitro carcinogenesi

Background factors influencing somatic and psychological symptoms in middle-age women with different hormonal status A population-based study of Swedish women.

Objective: To analyse the influence of socio-demographic characteristics and environmental factors on self-reported somatic and psychological symptoms among middle-aged Swedish women. Methods: A total of 6917 women living in the Lund area of southern Sweden were participates of this study. They completed a generic questionnaire pertaining to socio-demographic characteristics, lifestyle factors and

Predictors of deterioration of lung function in cystic fibrosis.

The severity of lung disease in cystic fibrosis (CF) may be related to the type of mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, and to environmental and immunological factors. Since pulmonary disease is the main determinant of morbidity and mortality in CF, it is important to identify factors that can explain and predict this variation. The aim of this longitudi

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
