Notes to the current checklist of Tardigrada

Abstract: Corrections and additions to the recently published checklist of Tardigrada taxa (Guidetti & Bertolani 2005) are defined and described until the acceptance of this article. Two new synonyms are stated here: Hypsibius iharosi Bartos, 1941 syn. nov. and Isohypsibius gibbus (Marcus, 1928) syn. nov.

A high-density consensus map of barley to compare the distribution of QTLs for partial resistance to Puccinia hordei and of defence gene homologues

Abstract: A consensus map of barley was constructed based on three reference doubled haploid (DH) populations and three recombinant inbred line (RIL) populations. Several sets of microsatellites were used as bridge markers in the integration of those populations previously genotyped with RFLP or with AFLP markers. Another set of 61 genic microsatellites was mapped for the first time using a newly developed fluorescent labelling strategy, referred to as A/T labelling. The final map contains 3,258 markers spanning 1,081 centiMorgans (cM) with an average distance between two adjacent loci of 0.33 cM. This is the highest density of markers reported for a barley genetic map to date. The consensus map was divided into 210 BINs of about 5 cM each in which were placed 19 quantitative trait loci (QTL) contributing to the partial resistance to barley leaf rust (Puccinia hordei Otth) in five of the integrated populations. Each parental barley combination segregated for different sets of QTLs, with only few QTLs shared by any pair of cultivars. Defence gene homologues (DGH) were identified by tBlastx homology to known genes involved in the defence of plants against microbial pathogens. Sixty-three DGHs were located into the 210 BINs in order to identify candidate genes responsible for the QTL effects. Eight BINs were co-occupied by a QTL and DGH(s). The positional candidates identified are receptor-like kinase, WIR1 homologues and several defence response genes like peroxidases, superoxide dismutase and thaumatin.

The effectiveness of strategies to change organisational culture to improve healthcare performance: a systematic review

Abstract: Organisational culture is an anthropological metaphor used to inform research and consultancy and to explain organisational environments. In recent years, increasing emphasis has been placed on the need to change organisational culture in order to improve healthcare performance. However, the precise function of organisational culture in healthcare policy often remains underspecified and the desirability and feasibility of strategies to be adopted have been called into question. The objective of this review was to determine the effectiveness of strategies to change organisational culture in order to improve healthcare performance. We searched the following electronic databases: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, Sociological Abstracts, Web of Knowledge, PsycINFO, Business and Management, EThOS, Index to Theses, Intute, HMIC, SIGLE, and Scopus until October 2009. The Database of Abstracts of Reviews of Effectiveness (DARE) was searched for related reviews. We also searched the reference lists of all papers and relevant reviews identified, and we contacted experts in the field for advice on further potential studies. We considered randomised controlled trials (RCTs) or well designed quasi-experimental studies (controlled clinical trials (CCTs), controlled before and after studies (CBAs), and interrupted time series (ITS) analyses). Studies could be set in any type of healthcare organisation in which strategies to change organisational culture in order to improve healthcare performance were applied. Our main outcomes were objective measures of professional performance and patient outcome. The search strategy yielded 4,239 records. After the full text assessment, two CBA studies were included in the review. They both assessed the impact of interventions aimed at changing organisational culture, but one evaluated the impact on work-related and personal outcomes while the other measured clinical outcomes. Both were at high risk of bias. Both reported positive results. Current available evidence does not identify any effective, generalisable strategies to change organisational culture. Healthcare organisations considering implementing interventions aimed at changing culture should seriously consider conducting an evaluation (using a robust design, e.g., ITS) to strengthen the evidence about this topic.

Homodimerization of adenosine A2A receptors: qualitative and quantitative assessment by fluorescence and bioluminescence energy transfer.

Abstract: The results presented in this paper show that adenosine A2A receptor (A2AR) form homodimers and that homodimers but not monomers are the functional species at the cell surface. Fluorescence resonance energy transfer (FRET) and bioluminescence resonance energy transfer (BRET) techniques have been used to demonstrate in transfected HEK293 cells homodimerization of A2AR, which are heptaspanning membrane receptors with enriched expression in striatum. The existence of homodimers at the cell surface was demonstrated by time-resolved FRET. Although agonist activation of the receptor leads to the formation of receptor clusters, it did not affect the degree of A2AR–A2AR dimerization. Both monomers and dimers were detected by immunoblotting in cell extracts. However, cell surface biotinylation of proteins has made evident that more than 90% of the cell surface receptor is in its dimeric form. Thus, it seems that homodimers are the functional form of the receptor present on the plasma membrane. A deletion mutant version of the A2A receptor, lacking its C-terminal domain, was also able to form both monomeric and dimeric species when cell extracts from transfected cells were analyzed by immunoblotting. This suggests that the C-terminal tail does not participate in the dimerization. This is relevant as the C-terminal tail of A2AR is involved in heteromers formed by A2AR and dopamine D2 receptors. BRET ratios corresponding to A2AR–A2AR homodimers were higher than those encountered for heterodimers formed by A2AR and dopamine D2 receptors. As A2AR and dopamine D2 receptors do indeed interact, these results indicate that A2AR homodimers are the functional species at the cell surface and that they coexist with A2AR/D2 receptor heterodimers.

Revising the past (while thinking in the future perfect tense)

Abstract: Accounting for organizational history is essential to any change process. We argue, however, that the intentional revision of that history also can be important. We treat history as malleable, because events and actions from the past are susceptible to reinterpretation as organizations try to align with the way they see themselves in the present and want to see themselves in the future. Because change is a prospective, future‐oriented process, whereas sensemaking is a retrospective, past‐oriented process, making sense of the future requires an ability to envision the future as having already occurred, i.e. to think in the future perfect tense. We offer an initial conceptual exploration of organizational change from a revisionist history perspective that turns on future perfect thinking, a view that enlarges our conceptualization of the ways in which history affects organizational adaptation and change.
