National Orange Show Photovoltaic Demonstration
National Orange Show Photovoltaic Demonstration created a 400KW Photovoltaic self-generation plant at the National Orange Show Events Center (NOS). The NOS owns a 120-acre state fairground where it operates an events center and produces an annual citrus fair known as the Orange Show. The NOS governing board wanted to employ cost-saving programs for annual energy expenses. It is hoped the Photovoltaic program will result in overall savings for the NOS, help reduce the State's energy demands as relating to electrical power consumption, improve quality of life within the affected grid area as well as increase the energy efficiency of buildings at our venue. In addition, the potential to reduce operational expenses would have a tremendous effect on the ability of the NOS to service its community
Recuperación del control después de un episodio de rabia en el aula: Diseño de intervención para niños con Síndrome de Asperger (SA)
Este proyecto se centra en el tratamiento de las emociones, concretamente en la rabia, con alumnos diagnosticados de Síndrome de Asperger (SA) y el apoyo de alumnos sin ninguna patología. Se trata de un diseño de un proyecto de intervención que se basa en estrategias de autocontrol después de un episodio de rabia, ya que estas personas presentan serias dificultades en las relaciones sociales, el desarrollo de las emociones y el control de las mismas. Se realizará con niños escolarizados en 4º curso de educación primaria. El programa tiene el fin de mejorar la inclusión de estos alumnos a nivel social, fomentando las habilidades sociales, la autoestima así como el control de las emociones para que desarrollen sus competencias emocionales plenamente.

Differential expression and localization of transient receptor potential vanilloid 1 in rabbit and human eyes
Producción CientíficaSummary. Introduction: The superfamily of transient
receptor potential (TRP) cation channels is involved in
nociception. Members of this family, such as the
vanilloid receptor type 1 (TRPV1) channel, are activated
by a wide range of stimuli including heat (>43°C), low
pH (<6.5), hypoxia, and hypertonicity. Here we report
TRPV1 expression in rabbit and human eyes.
Material and methods: We analyzed the expression
of TRPV1 mRNA by quantitative reverse transcription
polymerase chain reaction (qRT-PCR) and protein by
immunohistochemistry in eyes of New Zealand White
rabbits and humans.
Results: In rabbit and human eyes, TRPV1 protein
was present in all layers of the corneal epithelium, but
only in the basal layer of the conjunctiva. It was also in
the ciliary and lens epithelia of both species as well as in
the secretory cells of the rabbit lacrimal gland. The
retinal pigment epithelium was positive for this protein
in both species. TRPV1 was also present in rabbit Müller
cells, where it had a similar pattern of expression to
vimentin intermediate filaments. Analysis by qRT-PCR
showed that TRPV1 mRNA was found in all of the
structures where the protein was present. The highest
level was in the lens and the lowest in the retina.
Conclusion: TRPV1 is expressed in cells that are
particularly active in Ca2+ exchange as well as in cells
with significant water transport activity. Because TRPV1
is a Ca2+ channel, it probably functions in the regulation
of both water and Ca2+ movements in ocular tissues
Ibrutinib does not impact CCR7-mediated homeostatic migration in T-cells from chronic lymphocytic leukemia patients
Bruton’s tyrosine kinase inhibitor ibrutinib has significantly changed treatment landscape in chronic lymphocytic leukemia (CLL). Growing evidence supports ibrutinib to work beyond the effect on tumor cells by means of, for example, restoring functionality of the T-cell compartment and increasing circulating T-cell numbers. Recent evidence suggests T-cell enhanced expansion, rather than increased egress from secondary lymphoid organs (SLO), as a root cause for ibrutinib-induced lymphocytosis. However, whether the latter physiological change is also a consequence of a forced retention in blood remains undisclosed. Since CCR7 is the main chemokine receptor taking over the homing of T-cells from peripheral compartments to lymph nodes and other SLO, we aimed to investigate the impact of ibrutinib on CCR7 functionality in T-cells. To this end, we documented receptor expression in T-cells from a large cohort of ibrutinib-treated CLL patients, and performed different in vivo and in vitro migration models. Overall, our data confirm that CCR7 expression or receptor-mediated migration in CLL T-cells is not affected by ibrutinib. Furthermore, it does not modulate CCR7-driven homing nor nodal interstitial migration. Together, our results support that ibrutinib-induced CLL T-cell accumulation in the blood stream is not derived from an impairment of CCR7-driven recirculation between the SLO and bloodstream, and therefore T-cell expansion is the most plausible causeA.M.-J. was partially financed by Alfonso Martín Escudero Foundation.

PD-1 and LAG-3 expression in EBV-associated pediatric Hodgkin lymphoma has influence on survival
In pediatric Hodgkin lymphoma (HL), the inability of the cytotoxic microenvironment induced by EBV presence to eliminate tumor cells could reflect the fact that the virus might be able to induce the expression of exhaustion markers to evade an immune response. Therefore, the expression of exhaustion markers in pediatric EBV–associated HL was evaluated. A balance between cytotoxic GrB and Th1 Tbet markers with regulatory Foxp3 was proved in EBV+ cases. In addition, exclusively in EBV-associated cHL, a correlation between PD-1 and LAG-3 expression was observed. Furthermore, those cases also displayed a trend to worse survival when they expressed LAG-3 and inferior event-free survival when both PD-1 and LAG-3 molecules were present. Therefore, even though a cytotoxic and inflammatory environment was supposed to be triggered by EBV presence in pediatric cHL, it seems that the virus may also induce the synergic effect of inhibitory molecules LAG-3 and PD-1 in this series. These observations may reflect the fact that the permissive and exhausted immune microenvironment succeeds to induce lymphomagenesis.Fil: Jimenez, Oscar Eduardo.

Una sociedad para todas las edades: curso monográfico de ejercicio físico
The population trend changes (e.g., increased life expectancy or life-long learning) highlight the need to implement intervention policies that fit the needs and expectations of older people. With that objective, this text presents the design of a monographic course of physical exercise for students over 45 years of the Universidad Abierta de Personas Mayores, in the University of Burgos. The intervention will take place over one academic year, and consists of 15 sessions. It will be led by university students in grades Social Education, Early Childhood Education and Pedagogy, thus promoting intergenerational culture. In order to assess the results of the implementation of this training program, two evaluations will be conducted (pre and post intervention), with SF-36 Health Survey, which evaluates the quality of life. We conclude that many studies show healthy benefits for this group after the continued practice of physical exercise, besides preventing dependency and increasing the quality of life. Los cambios de tendencia de la población (como mayor esperanza de vida o el aprendizaje a lo largo de la vida) ponen de manifiesto la necesidad de implementar políticas de intervención que se ajusten a las necesidades y las expectativas de las personas mayores. Con tal objetivo, se presenta el diseño de un curso monográfico de ejercicio físico para los alumnos mayores de 45 años de la Universidad Abierta de Personas Mayores de la Universidad de Burgos. La intervención se llevará a cabo a lo largo de un curso académico, y consta de 15 sesiones. Será conducido por estudiantes universitarios de los grados de Educación Social, Educación Infantil y Pedagogía, para fomentar de esta forma la cultura intergeneracional. Con el fin de valorar los resultados de la aplicación del programa de entrenamiento, se llevarán a cabo dos evaluaciones (pre-post intervención) con el Cuestionario de Salud SF-36, el cual valora la calidad de vida. Concluimos que numerosos estudios evidencian los beneficios saludables que reporta para este colectivo la práctica continuada del ejercicio físico, además de prevenir la dependencia física y aumentar la calidad de vida
Can changes in deformation regimes be inferred from crystallographic preferred orientations in polar ice?
Creep due to ice flow is generally thought to be the main cause for the formation of crystallographic preferred orientations (CPOs) in polycrystalline anisotropic ice. However, linking the development of CPOs to the ice flow history requires a proper understanding of the ice aggregate's microstructural response to flow transitions. In this contribution the influence of ice deformation history on the CPO development is investigated by means of full-field numerical simulations at the microscale. We simulate the CPO evolution of polycrystalline ice under combinations of two consecutive deformation events up to high strain, using the code VPFFT (visco-plastic fast Fourier transform algorithm) within ELLE. A volume of ice is first deformed under coaxial boundary conditions, which results in a CPO. The sample is then subjected to different boundary conditions (coaxial or non-coaxial) in order to observe how the deformation regime switch impacts the CPO. The model results indicate that the second flow event tends to destroy the first, inherited fabric with a range of transitional fabrics. However, the transition is slow when crystallographic axes are critically oriented with respect to the second imposed regime. Therefore, interpretations of past deformation events from observed CPOs must be carried out with caution, particularly in areas with complex deformation histories
