    Synthetic approaches to radiochemical probes for imaging of bacterial infections

    This present review provides an account on the available synthetic strategies employed to radiolabel commercial and potential bacteria-selective probes fortomographic imaging. These molecular probes encompass leukocytes, antibodies, small molecules, peptides, antibiotics, macrolides, vitamins, oligomers and siderophores. Although this technique has shown to be a valuable tool for non-invasive infection imaging, more development is required to create easy-to-radiolabel kit solutions procedures for the preparation of the probes.http://www.elsevier.com/locate/ejmech2018-06-16hj2017Nuclear Medicin

    Priority setting in primary health care - dilemmas and opportunities: a focus group study

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>Swedish health care authorities use three key criteria to produce national guidelines for local priority setting: severity of the health condition, expected patient benefit, and cost-effectiveness of medical intervention. Priority setting in primary health care (PHC) has significant implications for health costs and outcomes in the health care system. Nevertheless, these guidelines have been implemented to a very limited degree in PHC. The objective of the study was to qualitatively assess how general practitioners (GPs) and nurses perceive the application of the three key priority-setting criteria.</p> <p>Methods</p> <p>Focus groups were held with GPs and nurses at primary health care centres, where the staff had a short period of experience in using the criteria for prioritising in their daily work.</p> <p>Results</p> <p>The staff found the three key priority-setting criteria (severity, patient benefit, and cost-effectiveness) to be valuable for priority setting in PHC. However, when the criteria were applied in PHC, three additional dimensions were identified: 1) viewpoint (medical or patient's), 2) timeframe (now or later), and 3) evidence level (group or individual).</p> <p>Conclusions</p> <p>The three key priority-setting criteria were useful. Considering the three additional dimensions might enhance implementation of national guidelines in PHC and is probably a prerequisite for the criteria to be useful in priority setting for individual patients.</p

    Open for collaboration : an academic platform for drug discovery and development at SciLifeLab

    The Science for Life Laboratory Drug Discovery and Development (SciLifeLab DDD) platform reaches out to Swedish academia with an industry-standard infrastructure for academic drug discovery, supported by earmarked funds from the Swedish government. In this review, we describe the build-up and operation of the platform, and reflect on our first two years of operation, with the ambition to share learnings and best practice with academic drug discovery centers globally. We also discuss how the Swedish Teacher Exemption Law, an internationally unique aspect of the innovation system, has shaped the operation. Furthermore, we address how this investment in infrastructure and expertise can be utilized to facilitate international collaboration between academia and industry in the best interest of those ultimately benefiting the most from translational pharmaceutical research - the patients

    Institutional profile : the national Swedish academic drug discovery &amp; development platform at SciLifeLab

    The Science for Life Laboratory Drug Discovery and Development Platform (SciLifeLab DDD) was established in Stockholm and Uppsala, Sweden, in 2014. It is one of ten platforms of the Swedish national SciLifeLab which support projects run by Swedish academic researchers with large-scale technologies for molecular biosciences with a focus on health and environment. SciLifeLab was created by the coordinated effort of four universities in Stockholm and Uppsala: Stockholm University, Karolinska Institutet, KTH Royal Institute of Technology and Uppsala University, and has recently expanded to other Swedish university locations. The primary goal of the SciLifeLab DDD is to support selected academic discovery and development research projects with tools and resources to discover novel lead therapeutics, either molecules or human antibodies. Intellectual property developed with the help of SciLifeLab DDD is wholly owned by the academic research group. The bulk of SciLifeLab DDD's research and service activities are funded from the Swedish state, with only consumables paid by the academic research group through individual grants

    Synthesis of Novel Aryl and Heteroaryl Acyl Sulfonimidamides via Pd-Catalyzed Carbonylation Using a Nongaseous Precursor

    No full text
    Hitherto unexplored aryl and heteroaryl acyl sulfonimidamides have been prepared through the development of a new Pd-catalyzed carbonylation protocol. This novel methodology, employing sulfonimidamides as nucleophiles and CO gas <i>ex situ</i> released from solid Mo(CO)<sub>6</sub> in a sealed two-chamber system, yields a wide range of carbamate protected acyl sulfonimidamides in good to excellent yields

    Exploring the antibacterial and hemolytic activity of shorter- and longer-chain beta-, alpha,beta-, and gamma-peptides, and of beta-peptides from beta2-3-aza- and beta3-2-methylidene-amino acids bearing proteinogenic side chains--a survey.

    The antibacterial activities of 31 different beta-, mixed alpha/beta-, and gamma-peptides, as well as of beta-peptides derived from beta2-3-aza- and beta3-2-methylidene-amino acids were assayed against six pathogens (Enterococcus faecalis, Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa), and the results were compared with literature data. The interaction of these peptides with mammalian cells, as modeled by measuring the hemolysis of human erythrocytes, was also investigated. In addition to those peptides designed to fold into amphiphilic helical conformations with positive charges on one face of the helix, one new peptide with hemolytic activity was detected within the sample set. Moreover, it was demonstrated that neither cationic peptides used for membrane translocation (beta3-oligoarginines), nor mixed alpha/beta- or gamma-peptides with somatostatin-mimicking activities display unwanted hemolytic activity
