We have studied a phosphate rock plant which produces dicalcium phosphate (DCP), used as a source of calcium and phosphorus for domestic animals. A by-product in the manufacturing process is calcium chloride which is used in the oil industry, the food industry and as road-salt. The objectives of our study were to describe the fluxes of radionuclides from the U-238 decay series and to estimate the

Human blood coagulation Factor V(FV) is a plasma protein with little procoagulant activity. Limited proteolysis at Arg(709), Arg(1018), and Arg(1545) by thrombin or Factor Xa (FXa) results in the generation of activated FV, which serves as a cofactor of FXa in prothrombin activation. Both thrombin exosites I and II have been reported to be involved in FV activation, but the relative importance of

This article addresses the role of proximity for knowledge collaboration between dedicated biotechnology firms (DBFs) and related actors. Innovation projects managed by a selection of eight Swedish DBFs are analysed in detail and classified with regard to their specific knowledge characteristics. Based on this classification, explanations to the relative importance of functional and relational pro

A temporal filtering technique, complementary to spectral filtering, has been developed for laser-induced fluorescence measurements. The filter is applicable in cases where the laser-induced interfering signals and the signal of interest have different temporal characteristics. For the interfering-signal discrimination a picosecond laser system along with a fast time-gated intensified CCD camera w

Lymphopenia is due to a frameshift mutation in Gimap5 on rat chromosome 4 and is linked to type 1 diabetes in the diabetes prone (DP) BB rat. The hypothesis that bone marrow derived cells confer the lymphopenia phenotype was tested by reciprocal bone marrow transplantation in 40-day-old lethally irradiated diabetes resistant (DR) congenic DR.lyp/lyp (lymphopenia and diabetes) and DR.+/+ (no lympho

The time trends of exposure to heavy metals are not adequately known. This is a worldwide problem with regard to the basis for preventive actions and evaluation of their effects. This study addresses time trends for the three toxic elements cadmium (U), mercury (Hg), and lead (Pb). Concentrations in erythrocytes (Ery) were determined in a subsample of the population-based MONICA surveys from 1990,

OBJECTIVES: To study the rates of elimination of total prostate-specific antigen (PSA-T), free PSA (PSA-F), and PSA complexed to alpha 1-antichymotrypsin (PSA-ACT) from blood after radical retropubic prostatectomy (RRP). METHODS: We obtained venous blood from 10 patients with prostate cancer who were undergoing RRP. We analyzed PSA-F and PSA-ACT and equimolar detection of both of these forms toget

Proton motions in hydrated proton conducting perovskites BaZr(0.90)A(0.10)O(2.95) (A = Y and Sc) have been investigated using quasielastic neutron scattering. The results reveal a localized motion on the ps time scale and with an activation energy of similar to 10-30 meV, in both materials. The temperature dependence of the total mean square displacement of the protons shows an onset of this motio

Objective: Reduced serum adiponectin levels have been found in obesity and type 2 diabetes and variations in the adiponectin gene (APM1) have been associated with type 2 diabetes and features of the metabolic syndrome in different populations. Study Design: Here, we investigated the expression of APM1 in adipose tissue and studied the relationship between variation in APM1 expression, the APM1 G27

CagA seropositivity is an important risk factor for gastric adenocarcinoma and duodenal ulcer. However, CagA seropositivity is also found in Helicobacter pylori-seronegative subjects. Is CagA seropositivity in these subjects a sign of a past H. pylori infection, or does it represent a false-positive reaction? This study investigates the intensity of the CagA immune reaction and the variation in Ca

Thromboembolism during pregnancy is a rare complication with a potential fatal outcome. Very little is known about long-term effects and therefore 104 women with thrombosis during pregnancy or puerperium were identified and their subjective complaints were assessed in a questionnaire. All had their thrombosis diagnosed by objective methods and the median follow-up time was 11 years. In spite of an

We investigated the organochlorine accumulation (p,p′-DDE and ∑PCB) and stable isotope ratios (N and C) in a migrating salmon (Salmo salar) population in the Baltic Sea. ∂15N in the entire population ranged from 11.7 to 13.7‰ and ∂13C ranged from −22.0 to −19.6‰. In the entire population, ∂15N were weakly related to p,p′-DDE and ∑PCB concentrations (r2=0.20 and 0.14, respectively). However, lipid

The water activity dependence of lipase kinetics in organic media was evaluated using lipases from Rhizopus oryzae and Candida rugosa immobilised on polypropene EP-100. The conversion studied was the transesterification of ethyl decanoate to hexyl decanoate with hydrolysis to decanoic acid as competing reaction. The reactions were carried out at controlled water activity in diisopropyl ether. Subs

Objectives: To apply the normalized resistance interpretation (NRI) method to Etest MIC results which have higher precision than conventional log(2) dilution MIC tests due to the inclusion of intermediate values. If successful, NRI might provide an objective tool for the definition of epidemiological MIC cut-off values. Methods: MICs of tigecycline and other antimicrobial agents were determined fo
