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
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
Nitric oxide (NO) is known to be an important relaxant of contractile activity in various muscles including the human uterine arteries. It has been suggested that NO plays a role in modulation of vascular action of arginin vasopressin (AVP), a strong vasoconstrictor of the human uterine arteries. Therefore, the purposes of this study were to investigate an involvement of endogenous NO in regulatio
Aim: The purpose of the study was to assess the association between seropositivity to various infectious agents and stable coronary artery disease (CAD), controlling simultaneously for a variety of potential confounders. We also investigated whether the choice of a larger reference group might affect the results, and whether or not seropositivity to multiple agents was associated with a systemic i
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
The judgment of the Court of First Instance in Microsoft represents a major success for the European Commission in its fight against abuses of a dominant position. The Court upholds the Commission's findings that Microsoft abused its dominant position by refusing to supply interoperability information that is indispensable for competitors to be able to viably compete in the work group server opera
Objective. The present study investigates the cross-sectional relationship between tobacco smoking and body fatness. Methods. This cross-sectional study consisted of 469,543 men and women who participated in the European Prospective Investigation into Cancer and Nutrition (EPIC) study between 1992 and 2000 providing anthropometric measurements and information on smoking. Adjusted multilevel mixed-
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
BACKGROUND: Polymorphisms of the vitamin D receptor (VDR) gene have been implicated in the genetic regulation of bone mineral density (BMD). However, the clinical impact of these variants remains unclear.OBJECTIVE: To evaluate the relation between VDR polymorphisms, BMD, and fractures.DESIGN: Prospective multicenter large-scale association study.SETTING: The Genetic Markers for Osteoporosis consor
The clinical significance and the effects of pharmacological treatment of patients with Alzheimer's disease (AD) were evaluated by measurement of acetylcholinesterase (AChE) in the cerebrospinal fluid (CSF). CSF-AChE of AD patients was lower, not significantly, compared with controls. However, CSF-AChE was significantly increased after treatment of AD patients with AChE inhibitors (donepezil and g
Of main concern in agent based computing is the conception that software agents can attain socially responsible behavior. This idea has its origin in the need for agents to interact with one another in a cooperating manner. Such interplay between several agents can be seen as a combinatorial play where the rules are fixed and the actors are supposed to closely analyze the play in order to behave r
Abstract in UndeterminedBearing in mind the potential and importance of enzymatic processes it is somewhat surprising that we are not yet able to fully exploit the possibilities that such processes offer. The main reason is that we do not know the mechanism on the molecular scale in terms of the interaction between the enzyme and the substrate or rather the assembly of substrate molecules (see Fig
The organization of conjugated polyelectrolytes (CPEs) interacting with biomolecules sets conditions for the biodetection of biological processes and identity, through the use of optical emission from the CPE. Herein, a well-defined CPE and its binding to DNA is studied. By using dynamic light scattering and circular dichroism spectroscopy, it is shown that the CPE forms a multimolecule ensemble i
Progesterone receptor (PR) was investigated immunohistochemically in the lower urinary tract of the male and female mouse. Estrogen receptor (ER)-subtype-deficient mice (ERKO, BERKO) were used to determine the possible regulation of PR expression in an ER-subtype-specific manner. PR was found to be co-expressed with ERgreek small letter alpha in cell nuclei of urothelium, lamina propria fibroblas
Measurements of the net CO2 flux between terrestrial ecosystems and the atmosphere using the eddy covariance technique have the potential to underpin our interpretation of regional CO2 source-sink patterns, CO2 flux responses to forcings, and predictions of the future terrestrial C balance. Information contained in FLUXNET eddy covariance data has multiple uses for the development and application
Background. It is of importance to study the risk factor control in treated hypertensives (tHT), both longitudinally within one country and between neighbouring countries, as hypertensive patients still run an increased cardiovascular risk in spite of treatment. Methods. In sample of 1135 tHT from Estonia and a similar number of age- and sex- matched Swedish tHT, the control of blood pressure and
1. Mossy fibre evoked activity in the cerebellar cortex elicited by peripheral electrical stimulation was studied in chloralose anesthetized cats. The distribution of intracortical field potentials in the C3 and D zones was mapped in order to determine if there is a spread of synaptic activity outside the mossy fibre termination area. This area was identified by the presence of short latency synap
