Qualified Person Learning Programme Development: An Example of the Tempus Joint Project Activity

The role of Qualified Person (QP) is a pivotal one in Quality Assurance within the pharmaceutical industry. The competences required are usually achieved through work experience and more formal forms of learning, such as postgraduate MSc and/or relevant short-term courses. Duties of QP in the pharmaceutical sector in Serbia used to be performed by expert pharmacists with the relevant industrial experience and a Postgraduate Specialization Degree in Drug Analysis and Quality Control. However, it has been recognized that the learning needs of QPs should be extended to include knowledge of drug formulation and manufacturing processes. Taking into account the pre-accession status of Serbia, harmonization with EU practice and policies has been emphasized. In particular, compliance with EU directives 2001/82/EC and 2001/83/EC, which detail the role of, and academic qualifications required by a QP will be necessary. In order to respond to this need which has been highlighted within the sector, the Faculty of Pharmacy, University of Belgrade took responsibility for establishing the relevant postgraduate course, and set this as one of the priorities of the current Tempus PQPharm Project. The aim of this work is to provide an example of an outcomes-based interactive approach to curriculum development performed through an international joint-project collaboration activity

The female voice in Lopez de Ubeda's La Picara Justina and Goethe's Wilhelm Meister

The thesis has grown out of a perceived similarity between two novels from quite different cultural periods and national literary contexts: Lopez de Ubeda's Spanish picaresque novel, La Picara Justina of 1605 and Goethe's Wilhelm Meister of 1795- 1829. Both novels deal with the problem of female self-presentation, and use similar stylistic (poetic) resources to give expression to the female voice. The Introduction argues for the appropriateness of adopting a double strategy - both analytic and historical - in order to provide both internal and external evidence to make the point that the authors studied are participating in a shared cultural tradition. Chapter I introduces an account of the Kabbalah's presentation of the divine Speaking Woman (the Shekhinah), analysed in terms derived from contemporary feminist discussion. Chapter II then traces Goethe's life-long interest in the Divine Feminine, as illustrated in his Faust, various poems, and his Autobiography. In Chapter III Goethe's Wilhelm Meister is analysed with regard to his presentation of key female figures and to his lending them a mode of aesthetic language that empowers them to express their true identity. The purpose of Chapter IV is to show that the protagonist Justina's development in Lopez de Ubeda's novel is represented in part by the series of Great Mother figures she encounters and in part by her identification with the Shekhinah model. Then, in Chapter V, the ways in which Justina is made to exploit the Spanish language, like her resourceful use of her female persona, are examined to bring out the similarity of her rhetoric to that employed by Goethe (and advocated by Luce Irigaray). In the Conclusion, some suggestions are offered as to possibly fruitful lines of investigation which this inquiry may open up

FHF-independent conduction of action potentials along the leak-resistant cerebellar granule cell axon

Neurons in vertebrate central nervous systems initiate and conduct sodium action potentials in distinct subcellular compartments that differ architecturally and electrically. Here, we report several unanticipated passive and active properties of the cerebellar granule cell’s unmyelinated axon. Whereas spike initiation at the axon initial segment relies on sodium channel (Nav)-associated fibroblast growth factor homologous factor (FHF) proteins to delay Nav inactivation, distal axonal Navs show little FHF association or FHF requirement for high-frequency transmission, velocity and waveforms of conducting action potentials. In addition, leak conductance density along the distal axon is estimated as o1% that of somatodendritic membrane. The faster inactivation rate of FHF-free Navs together with very low axonal leak conductance serves to minimize ionic fluxes and energetic demand during repetitive spike conduction and at rest. The absence of FHFs from Navs at nodes of Ranvier in the central nervous system suggests a similar mechanism of current flux minimization along myelinated axons

Electrical conductivity of poly (L lactic acid) and poly (3-hydroxybutyrate) composites filled with galvanostatically produced copper powder

This manuscript presents experimental studies of composite materials based on poly (L lactic acid) (PLLA) and poly (3-hydroxybutyrate) (PHB) matrices filled with electrolytic copper powder, having a very high dendritic structure. Volume fractions of the copper powder used as filler in all prepared composites were varied in the range 0.5-6.0 vol.%. Samples were prepared by hot moulding injection at 170 degrees C. Influence of particle size and morphology, as well as the influence of matrix type on conductivity and percolation threshold of the obtained composites were examined. Characterization included: electrical conductivity measurements using AC impedance spectroscopy (IS), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and Fourier-transform Infrared spectroscopy (FTIR). Presence of three-dimensional conductive pathways was confirmed. The obtained percolation thresholds of 2.83 vol.% for PLLA and 3.13 vol.% for PHB composites were measured, which is about three times lower than the ones stated in the literature for similar composites. This property is ascribed to different morphologies of the filler used in the present investigation

Potential Immune Biomarkers in Diagnosis and Clinical Management for Systemic Lupus Erythematosus

Background: There is still no reliable, specific biomarker for precision diagnosis and clinical monitoring of systemic lupus erythematosus. The aim of this study was to investigate the importance of the determination of immunofenotypic profiles (T, B lymphocytes and NK cells) and serum cytokine concentrations (IL-17 and IFN-alpha) as potential biomarkers for this disease. Methods: The study included 55 patients with SLE and 25 healthy controls. The proportion of T, B, NK cells were assessed in peripheral blood using flow cytometric assays while the serum cytokine concentration (IL-17 and IFNalpha) was determined by ELISA test. Results: ROC curve analysis showed good accuracy to distinguish between patients and healthy individuals for activated T cells (AUC=0.798; p<0.001), Treg (AUC= 0.651; p=0.036), and memory B cells (AUC=0.285; p=0.002). We found statistically significant difference (p=0.036) in the levels of serum IL-17 between patients with SLE (IL-17=49.27 pg/mL) and controls (IL-17= 28.64 pg/mL). Conclusions: Significant increase in the relative number of Treg lymphocytes, and decrease in memory B cells, as well as decrease level of IL-17, in SLE patients may be implicated in the pathogenesis of the disease. These parameters, as biomarkers, could distinguish SLE patients and no-SLE patients. Monitoring subpopulations of immune cells in peripheral blood using flow cytometry provides insight into abnormal T and B cell function in SLE. Progress in understanding the immunity at SLE, results in concrete benefits for the SLE patients, which include new clinical management and therapeutic strategies

PAK1 phosphorylation of MEK1 regulates fibronectin-stimulated MAPK activation

Activation of the Ras–MAPK signal transduction pathway is necessary for biological responses both to growth factors and ECM. Here, we provide evidence that phosphorylation of S298 of MAPK kinase 1 (MEK1) by p21-activated kinase (PAK) is a site of convergence for integrin and growth factor signaling. We find that adhesion to fibronectin induces PAK1-dependent phosphorylation of MEK1 on S298 and that this phosphorylation is necessary for efficient activation of MEK1 and subsequent MAPK activation. The rapid and efficient activation of MEK and phosphorylation on S298 induced by cell adhesion to fibronectin is influenced by FAK and Src signaling and is paralleled by localization of phospho-S298 MEK1 and phospho-MAPK staining in peripheral membrane–proximal adhesion structures. We propose that FAK/Src-dependent, PAK1-mediated phosphorylation of MEK1 on S298 is central to the organization and localization of active Raf–MEK1–MAPK signaling complexes, and that formation of such complexes contributes to the adhesion dependence of growth factor signaling to MAPK
