Search and analysis of blue straggler stars in open clusters

Aims. This paper presents a new homogeneous catalogue of blue straggler stars ( BSS) in Galactic open clusters. Methods. Photometric data for 216 clusters were collected from the literature and 2782 BSS candidates were extracted from 76 of them. Results. We found that the anticorrelation of BSS frequency vs. total magnitude identified in similar studies conducted on Galactic globular clusters exte

Inhibitory effects of PG-H/aggrecan and PG-M/versican on avian neural crest cell migration

Aggrecans and PG-M/versicans represent two newly defined families of hyaluronan-binding proteoglycans for which the function is still poorly understood. Using the avian neural crest as a model system, we have examined the molecular mechanisms entailed in the cell-proteoglycan interaction during embryonic cell motility. Both the primary cartilage aggrecan of the avian embryo (PG-H/aggrecan) and the

Experimental oscillator strengths in Th II

We have measured radiative lifetimes of ten Th II levels by using thelaser-induced fluorescence technique and branching fractions withFourier transform spectroscopy. By combining the new branching fractionswith a total of 23 lifetimes, from the present work and frommeasurements by Simonsen et al. (cite{Simonsen}), absolute oscillatorstrengths for 180 lines have been derived. Some of these new f-va

Res judicata in the court of justice case-law: Balancing legal certainty with legality?

Forms of res judicata - Unwritten principle of EU law - National procedural autonomy v. EC supremacy - Revision of decisions v. state liability - Finality of administrative decisions v. judicial decisions - Higher respect for judicial decisions than for administrative decisions - Res judicata not absolute - ECJ itself under demands of legal certainty - Analogy between res judicata rules and rules

Etanercept, infliximab, and leflunomide in established rheumatoid arthritis: clinical experience using a structured follow up programme in southern Sweden.

OBJECTIVE: To explore the feasibility of prospectively monitoring treatment efficacy and tolerability of infliximab, etanercept, and leflunomide over a two year period in patients with established rheumatoid arthritis (RA) in clinical practice using a structured protocol. METHODS: All patients with RA at seven centres in southern Sweden, for whom at least two disease modifying antirheumatic drugs,

Utility Theory and Structural Analysis. Essays in the History of Swedish Economic Thought.

The first paper in this study is "Cassel and Revealed Preference Theory." The background to the paper is the general agreement that P. Samuelson originated the revealed preference theory of consumer behaviuor in 1938, but that there has not been such unanimous consent regarding possible precursors of the theory. Among those pointed to as predecessors is Cassel. This claim is, however, not so easy

Exposure of HEp-2 Cells to Stress Conditions Influences Antinuclear Antibody Reactivity.

This study of stress-related antinuclear antibody (ANA) reactivity was undertaken with the objective of improving clinical ANA testing. ANA was determined by parallel enzyme-linked immunosorbent assays of crude nuclear protein antigen extracted from HEp-2 cells either grown under optimal conditions (providing nonstress ANA antigen) or exposed to stress (providing stress ANA antigen). The stress st

Limited contribution of Doppler velocimetry to the differential diagnosis of extrauterine pelvic tumors

OBJECTIVE: To compare the ability of transvaginal color and spectral Doppler and that of gray-scale ultrasound examination to discriminate between benign and malignant extrauterine pelvic tumors. METHODS: One hundred forty-nine consecutive women scheduled for laparotomy because of an extrauterine pelvic mass underwent ultrasound examination, including color and spectral Doppler techniques, within

Isomers in neutron-rich A approximate to 190 nuclides from Pb-208 fragmentation

Relativistic projectile fragmentation of Pb-208 has been used to produce isomers in neutron-rich, A approximate to 190 nuclides. A forward-focusing spectrometer provided ion-by-ion mass and charge identification. The detection of gamma-rays emitted by stopped ions has led to the assignment of isomers in Ta-188, W-190, Re-192, Re-193, Os-195, Ir-197, Ir-198, Pt-200, Pt-201, Pt-202 and Au-203, with

Working group on dry grasslands in the Nordic and Baltic region – Outline of the project and first results for the class Festuco-Brometea

The vegetation databank established by our working group covers the classes Festuco-Brometea, Koelerio-Corynephoretea, and Trifolio-Geranietea sanguinei in the Nordic and Baltic region, i.e. NE Germany, Denmark, Norway, Sweden, Finland, N Poland, Lithuania, Latvia, Estonia, and NW Russia. We aim to use these data to develop a consistent supra-national phytosociological classification of these xero

C. R. Koester. Hebrews (Anchor Bible, 36) 604 pp

This commentary on the Letter to the Hebrews is written for a broad public, but it still reflects the author's scholarly learning and insights into the rhetorical structure and the theological meaning of this letter. The commentary is divided into three parts: 1) Translation; 2) Notes; 3) Comments (theological implications). Koester has succeeded in combining sociological and rhetorical insights w

A case-control study of transmission routes for GB virus C/hepatitis G virus in Swedish blood donors lacking markers for hepatitis C virus infection

BACKGROUND AND OBJECTIVES: The transmission routes for GB virus-C (GBV-C)/hepatitis G virus (HGV) in blood donors unexposed to hepatitis C virus (HCV) are unknown. We performed a case-control study of risk factors for GBV-C/HGV exposure in blood donors. MATERIALS AND METHODS: After testing stored sera from 458 HCV-negative blood donors for GBV-C/HGV RNA and GBV-C/HGV E2 antibodies, 66 donors with

CTLA4ig induces long-term graft survival of allogeneic skin grafts and totally inhibits T-cell proliferation in LFA-1-deficient mice.

BACKGROUND: It was recently shown that some strains of mice are capable of rejecting transplants independently of B7 and CD40L signaling and that this rejection is mediated by CD8(+) T cells. LFA-1 is known to be important for CD8(+) T cell activation and cytotoxicity. Therefore, blockade of LFA-1 could be important in overcoming costimulation blockade, CD8(+) T-cell-mediated, resistant rejection.
