The concept of irreversibility plays a central role in most discussions of how to understand and determine human death. This seems to relativize death, since the possibilities of reversal will always depend on circumstance. I discuss the conceptual problems created by this fact, arguing that their seriousness depends on whether we take our conception of death to be a definition or criterion. Relat
Background: Phage Display technology is a well established technique for high throughput screening of affinity ligands. Here we describe a new compact chromato-panning procedure for selection of suitable binders from a phage peptide display library. Results: Both phages and E. coli cells pass non-hindered through the interconnected pores of macroporous gel, so called cryogel. After coupling a liga
Background: The duration of colonization with methicillin-resistant Staphylococcus aureus (MRSA) is not well known and there is debate as to whether a patient colonized with MRSA ever can be defined as 'MRSA-negative'. Methods: Since 2003 all notified MRSA cases have been systematically followed in Skane County, southern Sweden. Cultures are taken from the nares, throat, perineum and possible skin
There is little research on the personalities and emotional stability of persons who report being bullied or witnessing bullying at work. Men and women (N = 247) from 19 to 64 years of age and in manual labour completed a questionnaire concerning the psychosocial work climate, bullying and personality. Three groups were defined: bullied (N = 14), witnesses (N = 31) and non-bullied respondents (N =
Objective To determine the sensitivity and specificity of the 'ovarian crescent sign' (OCS) - a rim of normal ovarian tissue seen adjacent to an ipsilateral adnexal mass as a sonographic feature to discriminate between benign and malignant adnexal masses. Methods The patients included were a subgroup of patients participating in the International Ovarian Tumor Analysis (IOTA) Phase 2 study, which
Boschma R. Towards an evolutionary perspective on regional resilience, Regional Studies. This paper proposes an evolutionary perspective on regional resilience. It conceptualizes resilience not just as the ability of a region to accommodate shocks, but extends it to the long-term ability of regions to develop new growth paths. A comprehensive view on regional resilience is proposed in which histor
Population genetic structure was studied in paddyfield warblers Acrocephalus agricola breeding in NE Bulgaria, SE Russia and S Kazakhstan. We were particularly interested in the degree of genetic differentiation and gene flow of the Bulgarian population due to its geographical isolation, recent origin and unique migratory strategy. Analyses of mitochondrial DNA (mtDNA) showed that there was no div

Background and purpose An earlier Nordic Arthroplasty Register Association (NARA) report on 280,201 total hip replacements (THRs) based on data from 1995-2006, from Sweden, Norway, and Denmark, was published in 2009. The present study assessed THR survival according to country, based on the NARA database with the Finnish data included. Material and methods 438,733 THRs performed during the period
For the first time, various hydride phases in a zirconium-hydrogen system have been prepared in a high-energy synchrotron X-ray radiation beamline and their transformation behaviour has been studied in situ. First, the formation and dissolution of hydrides in commercially pure zirconium powder were monitored in real time during hydrogenation and dehydrogenation, then whole pattern crystal structur
The arterio-venous anastomoses (AVA) play a major role in the blood circulation in the peripheral body parts. In this work, the segmental bioheat model of Salloum et al. [1] is improved to accurately predict skin blood flow rate in the hands and fingers, and the local and overall human thermal responses in transient environments. The improvements in the model include: 1) extending the artery tree
Popular Abstract in Danish Genterapi er en attraktiv terapiform mod neurologiske lidelser som Parkinsons sygdom og epilepsi af flere grunde. Gener med en terapeutisk effekt kan introduceres lokalt ved præcise injektioner i det syge væv, hvor genproduktet kan frigives fra nerveceller i respons til aktivitet i det omgivende væv. Ved genterapi omgås den forhindring som blod-hjernebarrieren udgør, ligGene therapy is an attractive strategy for neurological disorders, such as Parkinson’s disease and epilepsy, for several reasons. Introduction of genes with a therapeutic potential can be achieved locally, by accurate injections in the compromised tissue, and release of a transgene therapeutic substance can be regulated by the surrounding host neural circuitry. The gene therapy approach circumvent
We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac
Background: With the rapid development of new genetic measurement methods, several types of genetic alterations can be quantified in a high-throughput manner. While the initial focus has been on investigating each data set separately, there is an increasing interest in studying the correlation structure between two or more data sets. Multivariate methods based on Canonical Correlation Analysis (CC
