Characterization of fusion from without induced by herpes simplex virus
1991
The process of fusion from without (FFWO) induced by herpes simplex virus (HSV) was analyzed by using various inhibitors and compared to fusion from within (FFWI). The fate of certain elements of the cytoskeleton after FFWO was also investigated. Our experiments demonstrate FFWO as a very suitable system for study of early virus-cell interactions. Zn++ ions proved inhibitory for penetration whilst pretreatment of cells with Ca++ ions before infection enhanced FFWO activity. Dissociation of penetration from the fusion process itself was possible by use of Zn++ ions, low pH-treatment and antiserum on the one hand and N-ethylmaleimide and cytochalasin D on the other. Penetration itself needs o…
Reversible stress-induced lipid body formation in fast twitch rat myofibers
2012
We analyzed the existence of lipid bodies (LBs) in the fast twitch rat flexor digitorum brevis (FDB) myofibers and found that these structures were scarce. However, isolation procedure of the myofibers, heath shock, viral infection or the glycosylation inhibitor tunicamycin induced formation of the LBs, which were stationary structures flanking Z lines. We next infected FDB myofibers with recombinant Semliki Forest virus expressing caveolin 3-yellow fluorescent protein (cav3-YFP) since this chimeric protein was targeted to the LBs facilitating their further analysis. Photobleaching experiments showed that the LBs recovered cav 3-YFP extremely slowly, indicating that they were not continuous…
Determination of phenoxy acid herbicides in drinking waters by HPLC and solid phase extraction
1998
Abstract An HPLC procedure for determining phenoxy acid herbicides in waters is described. A LichroSpher RP select B octadecyl-silane analytical column and spectrophotometric detection at 230 nm were used. Adequate retention was achieved with a mobile phase containing MeOH/phosphate buffer 10−2 M pH 2.5/PnOH (50/42/8, v/v). The herbicides were isolated from water samples by using a single solid phase extraction procedure with C18 solid-phase columns. An enrichment factor of 500 is achieved. The coefficients of variation of the method were generally lower than 2.7% at 0.4 μg L−1 herbicide concentration levels. Recoveries ranged between 93 and 118%. The results obtained indicate that the prop…

Physician pharmacist practice groups : consistency and feasibility in the primary healthcare system. Evaluation of an experiment in France
2022
The regulation of drug prescription by general practitioners is based on various mechanisms, but unlike other countries (Belgium, the Netherlands, Switzerland), it does not include practice groups between general practitioners and community pharmacists (GPMPs). This thesis analyses the coherence and, above all, the feasibility of such practice groups in our health system. The first chapter presents a macroeconomic and microeconomic analysis of the drug prescription by French general practitioners (GPs). It emphasises that it is an important target for regulatory policy because of its contribution to health expenditure but also its health impact, with prescriptions whose relevance could be i…

Variabilidad en la utilización de antihipertensivos entre las zonas básicas de salud de la Comunidad Valenciana
2010
ResumenObjetivosEstimar el consumo de cinco subgrupos terapéuticos empleados en el tratamiento de la hipertensión arterial en las zonas básicas de salud (ZBS) de la Comunidad Valenciana, y analizar sus variaciones.MétodosEstudio ecológico, descriptivo, del consumo de antihipertensivos en las ZBS de la Comunidad Valenciana en el año 2005, seguido de análisis de la variabilidad observada. Se estudiaron las 239 ZBS existentes mediante un análisis descriptivo de consumo (dosis diarias definidas [DDD] por 1.000 habitantes y día en pensionistas [DDD/1.000p/día] o activos [DDD/1.000a/día]) y razones estandarizadas de utilización. Para el análisis de la variabilidad se utilizaron los estadísticos d…
Efficacy and safety study of an eyelid gel after repeated nocturnal application in healthy contact lens users and non-users
2020
Purpose: To evaluate skin biocompatibility of a nighttime hydrating eyelid gel and possible ocular surface effects in contact lens users (CLU) and non-contact lens users (NCLU). The formulation is registered as a medical device as Tridocosahexaenoine-AOX® (TDHA-AOX) (a concentrated DHA triglyceride), containing also hyaluronic acid (HA). Methods: A prospective, randomized, masked clinical trial was performed with 62 participants of both sexes, aged 20–70 years, split into: (1) CLU (n = 30) and (2) NCLU (n = 32). All participants were instructed to apply a single dose of the moisturizing gel (containing TDHA-AOX and HA) nightly to the upper and inner eyelids of their right eye (RE) only, and…
Búsqueda de compuestos con potencial terapéutico para la enfermedad de Parkinson y estudio de la relación entre la enfermedad de Parkinson y la Diabe…
2022
La enfermedad de Parkinson (EP) es la segunda enfermedad neurodegenerativa más frecuente. Actualmente, la EP no tiene cura, y las terapias existentes solo son capaces de tratar los síntomas de esta enfermedad, pero no de ralentizar o de parar su progresión. Con el objetivo de descubrir nuevos fármacos que pudieran ser útiles para tratar esta enfermedad, hemos realizado un rastreo a gran escala, evaluando los compuestos incluidos en la quimioteca Prestwick (1120 compuestos). Para ello, estudiamos el efecto de estos compuestos sobre la actividad motora en un modelo de la EP en Drosophila basado en la mutación del gen DJ-1beta (ortólogo del gen humano DJ-1, cuya mutación es causante de casos f…
Sphingomonas fennica sp. nov. and Sphingomonas haloaromaticamans sp. nov., outliers of the genus Sphingomonas.
2007
Bacterial isolates obtained from polychlorophenol-contaminated sites in Finland (strain K101T) and from a Dutch drinking water well (strain A175T) were characterized taxonomically. 16S rRNA gene sequence analysis, determination of DNA G+C content, physiological characterization, estimation of the ubiquinone and polar lipid patterns and fatty acid content revealed that strains K101T and A175T were similar to Sphingomonas wittichii RW1T but also showed pronounced differences. The DNA G+C contents of the two novel strains were 63.6 and 66.1 mol%, respectively. On the basis of these results, two novel species of the genus Sphingomonas are described, for which the names Sphingomonas haloaromatic…
