    Reconfiguración socioespacial y autoorganización en las Villas 1, 11, 14 y Barrio 31 ex Villa 31 en la Ciudad Autónoma de Buenos Aires

    El proceso de evolución del espacio urbano en la Ciudad Autónoma de Buenos Aires fue escenario de reconfiguraciones que intentaron dar respuesta a las permanentes reestructuraciones que, en ocasiones surgen como respuesta a la aplicación de políticas neoliberales que afectan al tejido social y por consiguiente las relaciones espaciales tal como plantea Sousa Santos. Esto lleva a sectores populares a buscar una manera de habitar el espacio de la ciudad para poder situarse cerca de los centros laborales y abaratar los costos de transporte. El caso de la Ciudad Autónoma de Buenos Aires, en general, y de las urbanizaciones en Villa 1, 11, 14 y el Barrio 31, nos permiten considerar la importancia que adquieren los procesos de urbanización en los barrios populares y cómo a través de ellos se modifica la ciudad y las vidas de las personas. Ahora bien, estos procesos nos van a permitir pensar las ciudades como sistemas, que nacen crecen y se extienden. Es a partir de estos conceptos iniciales de la teoría del caos que nos permitimos abordar el desorden en la ciudad de buenos Aires, entendiendo por desorden los asentamientos irregulares y algunas fenómenos y comportamientos que son diversos.Instituto de Investigaciones en Humanidades y Ciencias Sociale

The co‐occurrence of downslope and along‐slope sedimentary processes makes it particularly difficult to differentiate these relatively homogeneous deposits. The main aim of this paper is to identify differences in deep‐water sediments based on Principal Component Analysis of grain size and geochemistry, sedimentary facies, and reinforced by microfacies and ichnofacies. The sediments studied were obtained from two International Ocean Drilling Program Expedition 339 sites in mounded and sheeted drifts in the Gulf of Cadiz. The statistical approach led to the discernment of hemipelagites, silty contourites, sandy contourites, bottom current reworked sands, fine‐grained turbidites and debrites over a range of depositional and physiographic elements. These elements are linked to contourite drifts, the drift‐channel transition, the contourite channel and distal upper slope. When bottom currents or gravity‐driven flows are not the dominant depositional process, marine productivity and continental input settling forms the main depositional mechanism in deep‐water environments. This is reflected by a high variability of the first principal component in hemipelagic deposits. The stacked principal component variability of these deposits evidences that the contourite drift and the adjacent contourite channel were influenced by the interrelation of hemipelagic, gravitational and bottom current induced depositional processes. This interrelation questions the paradigm that a drift is made up solely of muddy sediments. The interrelation of sedimentary processes is a consequence of the precession‐driven changes in the intensity of the Mediterranean Outflow Water related to Mediterranean climate variability, which are punctuated by millennial‐scale variability. Associated vertical and lateral shifts of the Mediterranean Outflow Water, and therefore of its interface with the East North Atlantic Central Water, controlled sediment input and favoured turbulent sediment transport in the middle slope. During the interglacial precession maxima/insolation minima, a more vigorous upper core of the Mediterranean Outflow Water and the enhanced impact of the East North Atlantic Central Water – Mediterranean Outflow Water interface allowed for the development of the sandier contourite deposits.BP within the "The Drifters" Research Group at Royal Holloway University of London (RHUL)ENI within the "The Drifters" Research Group at Royal Holloway University of London (RHUL)ExxonMobil within the "The Drifters" Research Group at Royal Holloway University of London (RHUL)TOTAL within the "The Drifters" Research Group at Royal Holloway University of London (RHUL)Wintershall Dea within the "The Drifters" Research Group at Royal Holloway University of London (RHUL)TGS within the "The Drifters" Research Group at Royal Holloway University of London (RHUL)AEI/FEDER, UE CTM 2012-39599-C03 CGL2015-66835-P CTM2016-75129C3-1-R CGL2016-80445-RB-RNM-072-UGR1

    Narrowing the Genetic Causes of Language Dysfunction in the 1q21.1 Microduplication Syndrome

    Get PDF
    The chromosome 1q21.1 duplication syndrome (OMIM# 612475) is characterized by head anomalies, mild facial dysmorphisms, and cognitive problems, including autistic features, mental retardation, developmental delay, and learning disabilities. Speech and language development are sometimes impaired, but no detailed characterization of language problems in this condition has been provided to date. We report in detail on the cognitive and language phenotype of a child who presents with a duplication in 1q21.1 (arr[hg19] 1q21.1q21.2(145,764,455-147,824,207) × 3), and who exhibits cognitive delay and behavioral disturbances. Language is significantly perturbed, being the expressive domain the most impaired area (with significant dysphemic features in absence of pure motor speech deficits), although language comprehension and use (pragmatics) are also affected. Among the genes found duplicated in the child, CDH1L is upregulated in the blood of the proband. ROBO1, a candidate for dyslexia, is also highly upregulated, whereas, TLE3, a target of FOXP2, is significantly downregulated. These changes might explain language, and particularly speech dysfunction in the proband

    The aim of this study is to examine whether a lecture on hypnosis can modify attitudes and misconceptions about hypnosis. The sample consisted of 97 health professionals from institutions of Havana City. Group 1 consisted of 46 participants who received a lecture on hypnosis. Group 2 consisted of 51 participants who received a lecture about Urology. The Valencia Scale of Attitudes and Beliefs toward HypnosisTherapist was applied before and after the lecture. Results indicated that there were significant differences between the groups in which Group 1 showed more positive attitudes toward hypnosis. However, both groups showed similar misconceptions about hypnosis and memory, which changed significantly in Group 1 after receiving the lecture about hypnosis, but not in Group 2. Therefore, the lecture about hypnosis had a significant impact in correcting participants" misconceptions about memory and hypnosis

    Enumeration and Characterization of Circulating Tumor Cells in Patients with Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization

    Circulating tumor cells (CTCs), and particularly circulating cancer stem cells (cCSC), are prognostic biomarkers for different malignancies and may be detected using liquid biopsies. The ex vivo culture of cCSCs would provide valuable information regarding biological aggressiveness and would allow monitoring the adaptive changes acquired by the tumor in real time. In this prospective pilot study, we analyzed the presence of EpCAM+ CTCs using the IsoFlux system in the peripheral blood of 37 patients with hepatocellular carcinoma undergoing transarterial chemoembolization (TACE). The average patient age was 63.5 ± 7.9 years and 91.9% of the patients were men. All patients had detectable CTCs at baseline and 20 patients (54.1%) showed CTC aggregates or clusters in their peripheral blood. The increased total tumor diameter (OR: 2.5 (95% CI: 1.3–4.8), p = 0.006) and the absence of clusters of CTCs at baseline (OR: 0.2 (95% CI: 0.0–1.0), p = 0.049) were independent predictors of a diminished response to TACE. Culture of cCSC was successful in five out of thirty-three patients, mostly using negative enrichment of CD45− cells, ultra-low adherence, high glucose, and a short period of hypoxia followed by normoxia. In conclusion, the identification of clusters of CTCs before TACE and the implementation of standardized approaches for cCSC culture could aid to predict outcomes and to define the optimal adjuvant therapeutic strategy for a true personalized medicine in hepatocellular carcinoma

    Circulating Tumor Cells in Hepatocellular Carcinoma: A Comprehensive Review and Critical Appraisal

    Get PDF
    Hepatocellular carcinoma (HCC) is the fifth most common neoplasm and a major cause of cancer-related death worldwide. There is no ideal biomarker allowing early diagnosis of HCC and tumor surveillance in patients receiving therapy. Liquid biopsy, and particularly circulating tumor cells (CTCs), have emerged as a useful tool for diagnosis and monitoring therapeutic responses in different tumors. In the present manuscript, we evaluate the current evidence supporting the quantitative and qualitative assessment of CTCs as potential biomarkers of HCC, as well as technical aspects related to isolation, identification, and classification of CTCs. Although the dynamic assessment of CTCs in patients with HCC may aid the decision-making process, there are still many uncertainties and technical caveats to be solved before this methodology has a true impact on clinical practice guidelines. More studies are needed to identify the optimal combination of surface markers, to increase the efficiency of ex-vivo expansion of CTCs, or even to target CTCs as a potential therapeutic strategy to prevent HCC recurrence after surgery or to hamper tumor progression and extrahepatic spreading
