Study to assess the compensation and skills of medical library professionals relative to information technology professionals*

Purpose: The study seeks to determine how medical library professionals performing information-technology (IT) roles are compensated and how their positions are designed compared to information technology staff in their institutions.

A study comparing centralized CD-ROM and decentralized intranet access to MEDLINE

Objective: The purpose of this study was to evaluate the efficacy of a decentralized intranet access in each medical department as opposed to centralized unique MEDLINE access in the medical library.

Molecular determinants of drug access to the receptor site for antiarrhythmic drugs in the cardiac Na+ channel.

The clinical efficacy of local anesthetic and antiarrhythmic drugs is due to their voltage- and frequency-dependent block of Na+ channels. Quaternary local anesthetic analogs such as QX-314, which are permanently charged and membrane-impermeant, effectively block cardiac Na+ channels when applied from either side of the membrane but block neuronal Na+ channels only from the intracellular side. This difference in extracellular access to QX-314 is retained when rat brain rIIA Na+ channel alpha subunits and rat heart rH1 Na+ channel alpha subunits are expressed transiently in tsA-201 cells. Amino acid residues in transmembrane segment S6 of homologous domain IV (IVS6) of Na+ channel alpha subunits have important effects on block by local anesthetic drugs. Although five amino acid residues in IVS6 differ between brain rIIA and cardiac rH1, exchange of these amino acid residues by site-directed mutagenesis showed that only conversion of Thr-1755 in rH1 to Val as in rIIA was sufficient to reduce the rate and extent of block by extracellular QX-314 and slow the escape of drug from closed channels after use-dependent block. Tetrodotoxin also reduced the rate of block by extracellular QX-314 and slowed escape of bound QX-314 via the extracellular pathway in rH1, indicating that QX-314 must move through the pore to escape. QX-314 binding was inhibited by mutation of Phe-1762 in the local anesthetic receptor site of rH1 to Ala whether the drug was applied extracellularly or intracellularly. Thus, QX-314 binds to a single site in the rH1 Na+ channel alpha subunit that contains Phe-1762, whether it is applied from the extracellular or intracellular side of the membrane. Access to that site from the extracellular side of the pore is determined by the amino acid at position 1755 in the rH1 cardiac Na+ channel.

Domino 1,3-Dipolar Cycloadditions of N-Alkyl-α-Amino Esters with Paraformaldehyde: A Direct Access to α-Hydroxymethyl α-Amino Acids

N-Alkyl-α-amino esters undergo a domino reaction, based on the iminium cation generation, with paraformaldehyde, followed by a 1,3-dipolar cycloaddition of the stabilized azometh­ine ylide with another equivalent of formaldehyde. The resulting products are oxazolidines, which can be transformed after hydrolysis into α-hydroxymethyl α-amino acid or its derivatives. The diastereoselective 1,3-dipolar cycloaddition was performed using sarcosine (–)-menthyl or (–)-8-phenylmenthyl esters affording the cyclic product with moderate enantiomeric ratio.

An overview of the Applications of Natural Language to Information Systems

This introduction provides an overview of the state-of-the-art technology in Applications of Natural Language to Information Systems. Specifically, we analyze the need for such technologies to successfully address the new challenges of modern information systems, in which the exploitation of the Web as a main data source on business systems becomes a key requirement. It will also discuss the reasons why Human Language Technologies themselves have shifted their focus onto new areas of interest very directly linked to the development of technology for the treatment and understanding of Web 2.0. These new technologies are expected to be future interfaces for the new information systems to come. Moreover, we will review current topics of interest to this research community, and will present the selection of manuscripts that have been chosen by the program committee of the NLDB 2011 conference as representative cornerstone research works, especially highlighting their contribution to the advancement of such technologies.

Changes in Access to Health Services of the Immigrant and Native-Born Population in Spain in the Context of Economic Crisis

Aim: To analyze changes in access to health care and its determinants in the immigrant and native-born populations in Spain, before and during the economic crisis. Methods: Comparative analysis of two iterations of the Spanish National Health Survey (2006 and 2012). Outcome variables were: unmet need and use of different healthcare levels; explanatory variables: need, predisposing and enabling factors. Multivariate models were performed (1) to compare outcome variables in each group between years, (2) to compare outcome variables between both groups within each year, and (3) to determine the factors associated with health service use for each group and year. Results: unmet healthcare needs decreased in 2012 compared to 2006; the use of health services remained constant, with some changes worth highlighting, such as the decline in general practitioner visits among autochthons and a narrowed gap in specialist visits between the two populations. The factors associated with health service use in 2006 remained constant in 2012. Conclusion: Access to healthcare did not worsen, possibly due to the fact that, until 2012, the national health system may have cushioned the deterioration of social determinants as a consequence of the financial crisis. Further studies are necessary to evaluate the effects of health policy responses to the crisis after 2012.

Talking with the “pouvoir constituant” in times of constitutional reform: The European Court of Justice on Private Applicants’ Access to Justice. Research Paper in Law 3/2003

[From the Introduction]. European lawyers, at least those dealing predominantly with institutional matters, are living particularly interesting times since the setting-up of the “European Convention on the Future of Europe” in December 2001.1 As the Convention’s mandate, spelled out in rather broad terms in the European Council’s declaration of Laeken,2 is potentially unlimited, and as the future constitution of the European Union (EU) will be ultimately adopted by the subsequent Intergovernmental Conference (IGC), there appears to be a great possibility to clarify, to simplify and also to reform many of the more controversial elements in the European legal construction. The present debate on the future of the European constitution also highlights the relationship between the pouvoir constituant3 and the European Courts, the Court of Justice (ECJ) and its Court of First Instance (CFI), who have to interpret the basic rules and principles of the EU.4 In that light, the present article will focus on a classic theme of the Court’s case law: the relationship between judges and pouvoir constituant. In the EU, this relationship has traditionally been marked by the ECJ’s role as driving force in the “constitutionalisation” of the EC Treaties – which has, to a large extent, been accepted and even codified by the Member States in subsequent treaty revisions. However, since 1994, the ECJ appears to be more reluctant to act as a “law-maker.”5 The recent judgment in Unión de Pequeños Agricultores (UPA)6 – an important decision by which the ECJ refused to liberalize individuals’ access to the Community Courts – is also interesting in this context. UPA may be seen as another proof of judicial restraint - or even as indicator of the beginning of a new phase in the “constitutional dialogue” between the ECJ and the “Masters of the Treaties.”
