    Get PDF
    Launched in January 2009, ANCIEN is a research project that runs for a 44-month period and involves 20 partners from EU member states. The project principally concerns the future of long-term care (LTC) for the elderly in Europe and addresses two questions in particular: 1) How will need, demand, supply and use of LTC develop? 2) How do different systems of LTC perform? This case study on Spain is part of the first stage in the project aimed at collecting the basic data and necessary information to portray long-term care in each country of the EU. It will be followed by analysis and projections of future scenarios on long-term care needs, use, quality assurance and system performance. State-of-the-art demographic, epidemiologic and econometric modelling will be used to interpret and project needs, supply and use of long-term care over future time periods for different LTC systems

    Chronic myeloid leukemia is characterized by the translocation t(9;22)(q34;q11) (Philadelphia chromosome). Although it is not frequent, additional chromosome abnormalities can be detected at diagnosis and some of them have been associated with adverse cytogenetic and molecular outcome. We report a case of Chronic myeloid leukemia presenting the translocation t(1;11)(q21;q23) and a cryptic Philadelphia chromosome. The presence of additional chromosome abnormalities could generate greater genetic instability, promoting the emergence of further alterations. Our findings suggest that t(1;11)(q21;q23) avoided good response to tyrosine kinase inhibitors therapy. The patient evolves with primary resistance and subsequently at the recent control the T315I mutation was detected.Fil: Gutierrez, Leandro German.

    PVP solid dispersions containing Poloxamer 407 or TPGS for the improvement of ursolic acid release

    Get PDF
    Solid dispersions (SDs) of ursolic acid (UA) were developed using polyvinylpyrrolidone K30 (PVP K30) in combination with non-ionic surfactants, such as D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) or poloxamer 407 (P407) with the aim of enhancing solubility and in vitro release of the UA. SDs were investigated using a 24 full factorial design, subsequently the selected formulations were characterized for water solubility, X-ray diffractometry (XRD), differential scanning calorimetry (DSC), particle diameter, scanning electron microscopy, drug content, physical-chemical stability and in vitro release profile. SDs showed higher UA water-solubility than physical mixtures (PMs), which was attributed by transition of the drug from crystalline to amorphous or molecular state in the SDs, as indicated by XRD and DSC analyses. SD1 (with P407) and SD2 (with TPGS) were chosen for further investigation because they had higher drug load. SD1 proved to be more stable than SD2, revealing that P407 contributed to ensure the stability of the UA. Furthermore, SD1 and SD2 increased UA release by diffusion and swelling-controlled transport, following the Weibull model. Thus, solid dispersions obtained with PVP k-30 and P407 proved to be advantageous to enhance aqueous solubility and stability of UA

    Guadua angustifolia Kunth is a bamboo species, which has been widely used in construction. G. angustifolia is considered a hygroscopic material due to its capacity of absorb water, leading to changes in dimensions, strength, and stiffness due to variation of moisture content. The fibre saturation point (FSP) is reached when at certain moisture content, the material does not present dimensional changes and does not undergo variations in the mechanical strength. Specimens from the upper, middle and upper part of the bamboo were analysed in order to determine the FSP. Two methods were used to determine the FSP; the first method used the dimensional variation of the material at different moisture contents. The results showed that FSP is around 34.05%. The second method allowed verifying the FSP of Guadua angustifolia Kunth from the analysis of the parallel compression strength at different moisture contents. This method found that FSP was around 34%. Finally, a modification factor due to moisture content for compression strength was presented, as well as the equation for linear expansion of the material.La Guadua angustifolia Kunth es una especie de bambú que ha sido ampliamente utilizado en la construcción. Gracias a su capacidad de absorber agua, la G. angustifolia experimenta cambios en sus dimensiones, resistencia y rigidez debido a la variación del contenido de humedad. El punto de saturación de las fibras (PSF) se alcanza cuando a un determinado contenido de humedad el material no presenta cambios dimensionales ni variaciones en la resistencia mecánica. Para determinar el PSF de G. angustifolia se analizaron probetas de la parte inferior, intermedia y superior de la guadua. Se utilizaron dos metodologías: el primer método midió la variación dimensional, encontrando que el PSF está alrededor de 34.05 %; el segundo determinó la variación de la resistencia a la compresión paralela, encontrando que el PSF está alrededor de 34 %. Por último, se presentaron los factores de modificación de la resistencia a compresión para diferentes contenidos de humedad, así como la ecuación de expansión lineal del material
