La animación a la lectura: un camino para alcanzar el hábito y el placer por la lectura en la Educación Primaria
El presente Trabajo Fin de Grado, tiene como fin principal dar a conocer una forma de tratar la animación a la lectura en el primer ciclo de Educación Primaria. A través de la metodología empleada por Montserrat Sarto, se pretende educar en el gusto por los libros, acercar a los estudiantes lecturas que puedan comprender, y fomentar la reflexión sobre lo leído. En concreto, en este trabajo se aborda una parte teórica y se elabora una propuesta didáctica dirigida a 1º de E. Primaria de un centro educativo de Valladolid, con el fin de acercar al alumnado a la lectura literaria y fomentar una actitud positiva hacia ella. De este modo, obtendremos una serie de resultados que nos proporcionarán un punto de vista sobre la animación a la lectura y su posible puesta en práctica de metodologías similares en mi futuro como docente.This end of course dissertation is meant to take a deeper look at the encouragement to read
that students receive during their first years at Primary Education. A methodology put into
practice by Montserrat Sarto aims to develop a passion for reading, based on texts that are
effortlessly readable for young children, and motivates them to ponder and dwell on what
they have just read. Particularly, this essay focuses on the theory behind the encouragement
to read and develops an academic approach that can be implemented and put into practice
with students from the first course of Primary Education at a school in Valladolid. This
approach seeks to inspire students to embrace literary texts, and foster a positive attitude
towards reading.Grado en Educación Primari
Multi-omic approach to evaluate the response of gilt-head sea bream (Sparus aurata) exposed to the UV filter sulisobenzone
Sulisobenzone (BP-4) is one of the benzophenone type UVfiltersmost frequently detected in aquatic ecosystems.
As a suspected endocrine disrupting compound, scarce information is available yet about other molecular effects
and its mechanismof action. Here, we used an integrated transcriptomic and metabolomic approach to improve
the current understanding on the toxicity of BP-4 towards aquatic species. Gilt-head sea bream individualswere
exposed at environmentally relevant concentrations (10 μg L-1) for 22 days. Transcriptomic analysis revealed 371
differentially expressed genes in liver while metabolomic analysis identified 123 differentially modulated features
in plasma and 118 in liver. Integration of transcriptomic and metabolomic data showed disruption of the
energy metabolism(>10 pathways related to the metabolismof amino acids and carbohydrateswere impacted)
and lipid metabolism (5 glycerophospholipids and the expression of 3 enzymes were affected), suggesting oxidative
stress.We also observed, for the first time in vivo and at environmental relevant concentrations, the disruption
of several enzymes involved in the steroid and thyroid hormones biosynthesis. DNA and RNA
synthesis was also impacted by changes in the purine and pyrimidine metabolisms. Overall, the multiomic
workflow presented here increases the evidence on suspected effects of BP-4 exposure and identifies additional
modes of action of the compounds that could have been overlooked by using single omic approaches.

Impact of the COVID-19 Pandemic on the Work Engagement of UK Active Employees
[Abstract] The objective of this investigation was to describe the work engagement perceived by UK
workers during the COVID-19 pandemic. A descriptive cross-sectional study was conducted. The
sample included 1085 participants, aged 18 years and older, living in the UK during the COVID-19
pandemic, who were active workers. Data were collected using an online questionnaire and the
UWES-9. They were analysed using descriptive statistics, a t-test for equality of means or ANOVA,
and the Chi-squared Automatic Interaction Detection method. The mean value in the UWES-9 was
3.46 (SD = 1.11). Participants with lower satisfaction (21.8%) gave significantly low or very low
UWES-9 scores in 58.5% of the cases. Greater work engagement was obtained with more resources
and less conflict, risk, and stress. In cases where there had been contact with COVID-19, this was
associated with slightly lower levels of work engagement. These results could motivate and guide
companies to adopt risk prevention measures and protocols to return to normal working conditions
after the initial crisis phase of the pandemic
Arterial stiffness is associated with adipokine dysregulation in non-hypertensive obese mice
This is the peer reviewed version of the following article: Vascular Pharmacology 77 (2016): 38-47, which has been published in final form at http://dx.doi.org/10.1016/j.vph.2015.05.012The aim of this study was to characterize alterations in vascular structure and mechanics in murine mesenteric arteries from obese non-hypertensive mice, as well as their relationship with adipokines. Four-week old C57BL/6J male mice were assigned either to a control (C, 10% kcal from fat) or a high-fat diet (HFD, 45% kcal from fat) for 32 weeks. HFD animals weighed 30% more than controls (p < 0.001), exhibited similar blood pressure, increased leptin, insulin and superoxide anion (O2radical dot−) levels, and reduced adiponectin levels and nitric oxide (NO) bioavailability. Arterial structure showed an outward remodeling with an increase in total number of both adventitial and smooth muscle cells in HFD. Moreover, HFD mice exhibited an increased arterial stiffness assessed by β-values (C = 2.4 ± 0.5 vs HFD = 5.3 ± 0.8; p < 0.05) and aortic pulse wave velocity (PWV, C = 3.4 ± 0.1 vs HFD = 3.9 ± 0.1; p < 0.05). β-Values and PWV positively correlated with leptin, insulin or O2radical dot− levels, whereas they negatively correlated with adiponectin levels and NO bioavailability (p < 0.01). A reduction in fenestrae number together with an increase in type-I collagen amount (p < 0.05) were observed in HFD. These data demonstrate that HFD accounts for the development of vascular remodeling and arterial stiffness associated with adipokine dysregulation and oxidative stress, independently of hypertension developmentThis work was supported by grants from Ministerio de Ciencia e Investigación (BFU2011-25303), Ministerio de Economía y Competitividad (SAF2009-09714, SAF2011-25303, BFU2012-35353), Grupos Universidad Complutense de Madrid (UCM; GR-921641), Fundación Universitaria CEU-San Pablo, Fundación Mutua Madrileña and Sociedad para el Estudio de la Salud Cardiometabólica (SESCAMET).

Disruption of the HLA-E/NKG2X axis is associated with uncontrolled HIV infections
The contribution of the HLA-E/NKG2X axis in NK-mediated control of HIV infection remains unclear. We have studied the relationship between HLA-E expression and phenotypical as well as functional characteristics of NK cells, in the context of chronic HIV infection and in an in vitro model of acute infection. High viremia in HIV+ individuals was related to increased HLA-E expression, and changes in NK subpopulations, especially a reduction of the CD56 bright as well as an increase in adaptive NK subpopulation. Uncontrolled HIV infection was also characterized by a reversion of the NKG2A/NKG2C expression ratio and a loss of positive and negative regulation of NK mediated by HLA-E. This was reflected in a lower cytotoxic, degranulation and cytokine production capacity, especially in CD56 bright and adaptive NK. In line with these results, HLA-E expression showed a positive correlation with viral growth inhibition in an in vitro model of acute infection at day 7, which was lost after 14 days of culture. Using HLA-E expressing K562 cells, we determined that only one out of 11 described HIV-derived HLA-E epitopes increased HLA-E surface stability. In spite of that, eight of the 11 epitopes were capable of increasing degranulation and three drove differences in NK-cell mediated cell lysis or cytokine secretion. In conclusion, our results indicate that HLA-E molecules presenting HIV-derived epitopes may sensitize target cells for NK lysis in early HIV infection. However, prolonged exposure to elevated HLA-E expression levels in vivo may lead to NK cell dysfunction and reduced viral control In chronic infection

An Aptamer against MNK1 for Non-Small Cell Lung Cancer Treatment
Lung cancer is the leading cause of cancer-related death worldwide. Its late diagnosis and consequently poor survival make necessary the search for new therapeutic targets. The mitogen-activated protein kinase (MAPK)-interacting kinase 1 (MNK1) is overexpressed in lung cancer and correlates with poor overall survival in non-small cell lung cancer (NSCLC) patients. The previously identified and optimized aptamer from our laboratory against MNK1, apMNKQ2, showed promising results as an antitumor drug in breast cancer in vitro and in vivo. Thus, the present study shows the antitumor potential of apMNKQ2 in another type of cancer where MNK1 plays a significant role, such as NSCLC. The effect of apMNKQ2 in lung cancer was studied with viability, toxicity, clonogenic, migration, invasion, and in vivo efficacy assays. Our results show that apMNKQ2 arrests the cell cycle and reduces viability, colony formation, migration, invasion, and epithelial-mesenchymal transition (EMT) processes in NSCLC cells. In addition, apMNKQ2 reduces tumor growth in an A549-cell line NSCLC xenograft model. In summary, targeting MNK1 with a specific aptamer may provide an innovative strategy for lung cancer treatment.R.C.-M. was supported for predoctoral contracts (PEJD 2016-BMD-2145 and 2018-BMD-9201) from the Community of Madrid and grant RTC2019-07227-1.
