Determination of essential biomarkers in lung cancer: a real-world data study in Spain with demographic, clinical, epidemiological and pathological c…
2022
Abstract Background The survival of patients with lung cancer has substantially increased in the last decade by about 15%. This increase is, basically, due to targeted therapies available for advanced stages and the emergence of immunotherapy itself. This work aims to study the situation of biomarker testing in Spain. Patients and methods The Thoracic Tumours Registry (TTR) is an observational, prospective, registry-based study that included patients diagnosed with lung cancer and other thoracic tumours, from September 2016 to 2020. This TTR study was sponsored by the Spanish Lung Cancer Group (GECP) Foundation, an independent, scientific, multidisciplinary oncology society that coordinates…
Física (2010/2011)
2010
La Física es una ciencia que tiene por objeto el estudio de las propiedades de la materia y sus interacciones, por lo cual permite conocer la base de muchos procesos biológicos y de algunas de las más avanzadas técnicas de medida. Este curso pretende una iniciación en aquellos conceptos de la Física que puede necesitar un biológo/a en el desarrollo de su vida profesional.
Solar UV-B radiation affects leaf quality and insect herbivory in the southern beech tree Nothofagus antarctica
2004
We examined the effects of solar ultraviolet-B (UV-B) radiation on plant-insect interactions in Tierra del Fuego (55°S), Argentina, an area strongly affected by ozone depletion because of its proximity to Antarctica. Solar UV-B under Nothofagus antarctica branches was manipulated using a polyester plastic film to attenuate UV-B (uvb-) and an Aclar film to provide near-ambient UV-B (uvb+). The plastic films were placed on both north-facing (i.e., high solar radiation in the Southern Hemisphere) and south-facing branches. Insects consumed 40% less leaf area from north- than from south-facing branches, and at least 30% less area from uvb+ branches than from uvb-branches. The reduced herbivory …
Valoración de la ingesta dietética a nivel poblacional mediante cuestionarios individuales: sombras y luces metodológicas
2007
El desarrollo de la moderna metodología necesaria para caracterizar con rigor la ingesta de individuos y poblaciones data de hace sólo dos décadas, cuando germinó la epidemiología nutricional. La razón del carácter reciente de esta disciplina radica en el hecho de que la valoración de la ingesta dietética a nivel poblacional presenta retos complejos, que sólo van siendo superados a medida que investigamos y mejoramos los instrumentos metodológicos disponibles. En el presente artículo se revisan los métodos alternativos para estimar la ingesta de alimentos y nutrientes en los individuos. Tras una sucinta descripción de los métodos indirectos y directos de valoración del consumo alimentario, …

Characterizing the Invasive Tumor Front of Aggressive Uterine Adenocarcinoma and Leiomyosarcoma
2021
The invasive tumor front (the tumor–host interface) is vitally important in malignant cell progression and metastasis. Tumor cell interactions with resident and infiltrating host cells and with the surrounding extracellular matrix and secreted factors ultimately determine the fate of the tumor. Herein we focus on the invasive tumor front, making an in-depth characterization of reticular fiber scaffolding, infiltrating immune cells, gene expression, and epigenetic profiles of classified aggressive primary uterine adenocarcinomas (24 patients) and leiomyosarcomas (11 patients). Sections of formalin-fixed samples before and after microdissection were scanned and studied. Reticular fiber archit…
Risk assessment of mycotoxins in cereals = Evaluación del riesgo de micotoxinas en cereales
2015
Las micotoxinas son un grupo de sustancias producidas por diferentes especies de hongos filamentosos. La presencia de micotoxinas en los alimentos constituye un problema de salud pública a nivel mundial. En la Unión Europea se han establecido contenidos máximos en materias primas y alimentos para 14 micotoxinas, consideradas de mayor relevancia para la salud del consumidor. En la actualidad se está prestando atención a otros grupos de micotoxinas menos estudiadas, como las micotoxinas emergentes de Fusarium, entre las que se encuentran la beauvericina, las eniatinas y la fusaproliferina. Se trata de micotoxinas de creciente interés en el campo de la seguridad alimentaria por presentar una e…

Violent and/or delinquent women: a vision from the biopsychosocial perspective
2016
Violence and/or delinquency in women have been masked to some extent by society. Thus, the main goal of this work is to deeply analyse the published works on these matters, in order to understand this phenomenon from a neurobiological perspective. Firstly, the theory of the cycle of violence as a facilitating mechanism of violence in women will be analysed, with a special emphasis on neuroanatomical correlates. Subsequently, the relation between drug consumption and violence in women will be explained. Finally, the main biological correlates known as facilitating mechanisms of violence in women will be exhaustively described. The main risk factors for the facilitation of violence and/or del…
