This study investigates the influence on the realism of confidence judgments of four different factors, the individual, the knowledge domain (crystallized and fluid intelligence), gender and cognitive style (Need-for-Cognition, NfC). Seventy-nine high-school students answered questions on word knowledge (WORD) and logical/spatial ability (DTK), both tests were administered on three occasions with

Photon quality correction factors (kQγ) for ionization chamber photon dosimetry in an epithermal neutron beam were determined according to a modified absorbed dose to water formalism which was extended to mixed radiation fields. We have studied two commercially available ionization chambers in the epithermal neutron beam optimized for BNCT at the facility at Studsvik, Sweden. One of the chambers i

RNA repair has now been demonstrated to be a genuine biological process and appears to be present in all three domains of life. In this article, we consider what this might mean for the transition from an early RNA-dominated world to modem cells possessing genetically encoded proteins and DNA. There are significant gaps in our understanding of how the modem protein-DNA world could have evolved fro

The role of fibroblasts in inflammatory processes and their cross-talk with T cells is increasingly being recognized. Our aim was to explore the capacity of dermal fibroblasts to produce inflammatory chemokines potentially involved in fibrosis occurring in response to contact with polarized human T cells. Our findings indicate that the program of chemokine production by fibroblasts is differential

Lipoproteins consist of lipids solubilized by apolipoproteins. The lipid-binding structural motifs of apolipoproteins include amphipathic alpha-helixes and beta-sheets. Plasma apolipoprotein (apo) M lacks an external amphipathic motif but, nevertheless, is exclusively associated with lipoproteins ( mainly high density lipoprotein). Uniquely, however, apoM is secreted to plasma without cleavage of

FUS (TLS) was first identified as the 5'-part of a fusion gene with CHOP (GADD153, DDIT3) in myxoid liposarcomas with t(12; 16)(q13; p11). Homologies were found with the EWS oncogene, which is rearranged in Ewing sarcomas and other neoplasias. The genomic structure of FUS shows extensive similarities with that of EWS, but the exon/intron structures differ in the 5' parts, and overall FUS is smalle

Introduction: Ximelagatran is a novel, oral direct thrombin inhibitor that is currently being investigated for the prophylaxis and treatment of thromboembolic events. This study evaluated the pharmacokinetics, pharmacodynamics, and clinical effects of melagatran, the active form of ximelagatran, in patients with both deep vein thrombosis (DVT) and pulmonary embolism (PE). Materials and methods: In

Transfer of deoxyribonucleoside kinases (dNKs) into cancer cells increases the activity of cytotoxic nucleoside analogues. It has been shown that bacterial dNKs, when introduced into Escherichia coli, sensitize this bacterium toward nucleoside analogues. We studied the possibility of using bacterial dNKs, for example deoxyadenosine kinases (dAKs), to sensitize human cancer cells to gemcitabine. St

Fibroblast growth factor 8 (FGF-8) is expressed at an increased level in a high proportion of prostate cancers and it is associated with a poor prognosis of the disease. Our aim was to study the effects of FGF-8b on proliferation of PC-3 prostate cancer cells and growth of PC-3 tumors, and to identify FGF-8b-associated molecular targets. Expression of ectopic FGF-8b in PC-3 cells caused a 1.5-fold

The paper tests the hypothesis that highly leveraged firms lose market shares to their less leveraged rivals in an industry downturn. Both parametric and semiparametric regression methods are applied to analyse the relationships between firm performance and leverage. It is found that the highly leveraged firms in distressed industries face relatively lower sales growth and stock returns but are st

Ferrochelatase is the terminal enzyme in the heme biosynthetic pathway. It catalyzes the insertion of ferrous iron into protoporphyrin IX to produce protoheme IX. The crystal structures of ferrochelatase from Saccharomyces cerevisiae in free form, in complex with Co(II), a substrate metal ion, and in complex with two inhibitors, Cd(II) and Hg(I), are presented in this work. The enzyme is a homodim

Background Knowledge about how elderly persons perceive the impact of chronic heart failure (CHF) on daily life is important when planning nursing care. For this purpose, disease specific instruments are needed. However, few instruments have been developed or tested specifically on elderly persons. Aim To validate a Swedish version of the Minnesota Living with Heart Failure Questionnaire (LHFQ)

To improve image quality in the upper thoracic spine, an anatomically shaped copper wire loop coil, made to fit over the patient's shoulders, was constructed. The coil was permanently mounted on a foam-rubber vest to facilitate attachment to the patient. Phantom and in vivo studies of the performance of the coil in healthy volunteers showed as much as a two times greater signal-to-noise ratio rela

Polyphosphoinositides (PIP) and (PIP2) show prominent negative singly and doubly charged deprotonated molecules in electrospray mass spectrometry. These ions can be used for quantification of PIP and PIP2 in the low picomole range, without prior chromatographic separation, using selected ion monitoring and consecutive measurements of the signals from the deprotonated singly charged molecules. The

1. The cereal field carabid beetle Amara similata was selected to elucidate the role of seeds and insects as food sources. Three experiments were performed to rank different weed seeds and insects in terms of food value: (i) fecundity in relation to adult diet, (ii) larval survival in relation to diet and (iii) larval survival in relation to parental diet. 2. Seeds were found to be of high value
