The concentration of the protein S100B in serum is used as a brain damage marker in various conditions. We wanted to investigate whether a voluntary, prolonged apnea in trained breath-hold divers resulted in an increase of S100B in serum. Nine trained breath-hold divers performed a protocol mimicking the procedures they use during breath-hold training and competition, including extensive preapneic
Aims: To devise clinically applicable methods for assessing p53 and Ki67 immunohistochemical (IHC) reactivity in Barrett's oesophagus (BE) and to compare the interobserver agreement between these methods and routine haematoxylin and eosin (H&E) evaluation. Methods and results: One hundred and fifteen biopsies diagnosed as BE, selected from the files of the University Hospital MAS, Malmö, were
The effects of exogenously added nerve growth factor (NGF) on reaggregation cultures of foetal rat brain cells after X-irradiation with 2 Gy were studied. Irradiation caused decreased protein and DNA levels, which was not prevented by NGF. The activities of the cholinergic marker enzymes choline acetyl transferase and acetylcholine esterase were increased in irradiated cultures. However, no differ
Transplantation of genetically manipulated cells to the central nervous system holds great promise for the treatment of several severe neurological disorders. The success of this strategy relies on sufficient levels of transgene expression after transplantation. This has been difficult to achieve, however, due to transgene silencing. In this study, we transduced the neural stem cell line RN33B wit
The fission probability and the angular distribution of the associated fission fragments have been measured for the U-235(d,pf)U-236 reaction slightly above the top of the inner fission barrier with the aim of disclosing new hyperdeformed states lying in the third minimum of the fission potential. The results are analyzed together with the data obtained from the literature for U-234. The experimen
The development of science parks constitutes an interesting example of policy to enhance the technology-based development of a region. These parks, it is argued, contribute to fostering technological innovation and transfer and stimulating the growth of high-level economic activities. This article examines the role that science parks play in the promotion of regional development with particular re
Hormone-sensitive lipase (HSL) is a key enzyme in fatty acid mobilization in many cell types. Two isoforms of HSL are known to date, namely HSLadi (84 kDa in rat) and HSLtes (130 kDa in rat). These are encoded by the same gene, with exons 1-9 encoding the parts that are common to both and an additional 5'-exon encoding the additional amino acids in HSLtes. HSL of various tissues, among these the i
A simple method for measuring synovial fluid (SF) volume is described. The degree of dilution of SF albumin after intraarticular injection of a defined volume of saline was used to calculate residual SF volume. Good correlation between calculated and aspirated SF volume was found for knee joint exudates. The method is simple, requires no radioactive tracer and should be useful in quantitative stud
The aim of this study was to evaluate a new approach to inhibit complement activation triggered by biomaterial surfaces in contact with blood. In order to inhibit complement activation initiated by the classical pathway (CP), we used streptococcal M protein-derived peptides that specifically bind human C4BP, an inhibitor of the CP. The peptides were used to coat polystyrene microtiter wells which
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
Background: Evidence points to a link between systemic lupus erythematosus (SLE) and an increased risk of lung cancer. Our objective was to provide a brief report of the lung cancer cases from an SLE cohort, with respect to demographics, histology, and exposures to smoking and immunosuppressive medications. Methods: Data were obtained from a multi-site international cohort study of over 9500 SLE p
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
