El bienestar del menor por nacer: ¿un interés a ponderar en el acceso a las técnicas de reproducción asistida?
2020
La necesidad de aproximar las legislaciones de los distintos Estados europeos en el ámbito de la reproducción asistida, para evitar el llamado “turismo reproductivo”; así como la conveniencia de realizar una valoración previa de las personas que solicitan ser receptoras de estas técnicas con fines reproductivos, en orden a acercar las distintas formas de filiación, hace que nos planteemos en el presente trabajo la introducción del “bienestar del menor por nacer” como un “interés” más a ponderar para acceder a las técnicas de reproducción asistida. The need to approximate the legislation of the different European States in the field of assisted reproduction, in order to prevent the so-called…
El Grand Débat National de Francia : análisis de un proceso participativo multicanal.
2021
En una época de cambios tecnológicos y sociales, la ciudadanía demanda nuevos canales de participación pública. En los últimos tiempos distintos procesos de participación recurren a la opinión ciudadana para adoptar decisiones. El movimiento de los chalecos amarillos desencadenó una ola de protestas en Francia a la que quiso hacerse frente con el Grand Débat National, un proceso participativo multicanal, a distintos niveles administrativos. El estudio de su desarrollo y resultados debe servir para diseñar futuros procesos similares.
Abordaje supracerebeloso transtentorial suprameatal a la totalidad de la región mediobasal del lóbulo temporal
2015
La región mediobasal del lóbulo temporal (RMT), por su compleja anatomía y su localización, constituye a día de hoy un reto neuroquirúrgico de primer orden. El desarrollo de la cirugía microquirúrgica de base craneal y los nuevos horizontes de la cirugía endoscópica siguen sin ofrecer un abordaje óptimo para aquellas lesiones asentadas en la totalidad de la RMT (principalmente oncológicas y vasculares). La exposición parcial de la RMT y el compromiso de estructuras neurovasculares no implicadas en la patología a tratar suponen los principales inconvenientes a la hora de plantear el abordaje de dichas lesiones. Las lesiones con frecuencia tumorales, que afectan la totalidad de la RMT, requie…
Strategies to gain novel Alzheimer’s disease diagnostics and therapeutics using modulators of ABCA transporters
2021
Adenosine-triphosphate-(ATP)-binding cassette (ABC) transport proteins are ubiquitously present membrane-bound efflux pumps that distribute endo- and xenobiotics across intra- and intercellular barriers. Discovered over 40 years ago, ABC transporters have been identified as key players in various human diseases, such as multidrug-resistant cancer and atherosclerosis, but also neurodegenerative diseases, such as Alzheimer���s disease (AD). Most prominent and well-studied are ABCB1, ABCC1, and ABCG2, not only due to their contribution to the multidrug resistance (MDR) phenotype in cancer, but also due to their contribution to AD. However, our understanding of other ABC transporters is limited…
Aroniju ogu fitoķīmiskā sastāva izvērtējums
2019
Aroniju ogu fitoķīmiskā sastāva izvērtēšana. Batarāga A. Zinātniskā vadītāja Asoc.prof. Dr. ķīm. Prikšāne A., konsultante Mg.ķīm. Valkovska V. Maģistra darbs, 76 lappuses, 46 attēli, 20 tabulas, 44 literatūras avoti. Latviešu valodā. Darbā analizēts aroniju ogu fitoķīmiskais sastāvs, nosakot kopējo fenolu, flavonoīdu saturu un antiradikālo aktivitāti. Lai pagatavotu analizējamos paraugus, izmantotas gan sasaldētas, gan ţāvētas ogas un kā ekstrahenti – 70 % etanola/ūdens, 10 % glicerīna/etanola un daţādu koncentrāciju un pH vērtību etanola/ūdens/HCl maisījumi. Pēc ultraskaľas veicinātas ekstrakcijas un 1 – 3 nedēļu ilgas macerācijastika noteikts kopējo fenolu saturs, izmantojot FolinCiocalte…

Phytosociology and ecology of deciduous forests in Tajikistan (Middle Asia)
2017
Aims: To present the first syntaxonomical classification for the mesophilous deciduous forests of the PamirAlai Mountains in Tajikistan with some remarks on its environmental gradients. Location: Tajikistan. Methods: Altogether 201 relevés were sampled between 2008‒2013 using the seven-degree cover-abundance scale of Braun-Blanquet. They were classified by the modified TWINSPAN method using the four-step interval scale with cutoff levels of 0%, 2%, 5% and 10% and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. Detrendended Correspondence Analysis was used to determine the relation between samples, veget…
Achlya spiralis, a new aquatic oomycete with bent oogonial stalks, isolated from the Burgundian region of France
2008
Achlya spiralis sp. nov. was isolated from water samples collected in the river Tille in the Burgundian region of France. The new oomycete is described, illustrated and compared with related species of the genus Achlya. It is characterized by the presence of smooth-walled oogonia that are usually borne on bent or twisted oogonial stalks; mainly monoclinous, androgynous and diclinous antheridial branches and eccentric oospores which generally do not mature or mature after a long period of time. The internal transcribed spacer (ITS) region of its rRNA is comprised of 671 bases. The taxonomic description of this new species, its comparison with related oomycetes and the sequence of the ITS reg…
Systematic Analysis of Combined Thrombolysis Using Ultrasound and Different Fibrinolytic Drugs in an in Vitro Clot Model of Intracerebral Hemorrhage.
2021
Adequate removal of blood clots by minimally invasive surgery seems to correlate with a better clinical outcome in patients with intracerebral hemorrhages (ICHs). Moreover, neurotoxic effects of recombinant tissue plasminogen activator have been reported. The aim of this study was to improve fibrinolysis using an intra-clot ultrasound application with tenecteplase and urokinase in our established ICH clot model. One hundred thirty clots were produced from 25 or 50 mL of human blood, incubated for different periods and equipped with drainage, through which an ultrasound catheter was placed in 65 treatment clots for 1 h, randomly allocated into three groups: administration of ultrasound, admi…
Long-term monitoring of mrk 501 for its very high energy γ emission and a flare in 2011 october
2012
"As one of the brightest active blazars in both X-ray and very high energy γ -ray bands, Mrk 501, is very useful for" "physics associated with jets from active galactic nuclei. The ARGO-YBJ experiment has monitored Mrk 501 for γ - rays above 0.3 TeV since 2007 November. The largest flare since 2005 was observed from 2011 October and lasted until about 2012 April. In this paper, a detailed analysis of this event is reported. During the brightest γ -ray flaring episodes from 2011 October 17 to November 22, an excess of the event rate over 6σ is detected by ARGO-YBJ in the direction of Mrk 501, corresponding to an increase of the γ -ray flux above 1 TeV by a factor of 6.6 ± 2.2 from its steady…
