[spa] Objetivos: Abordar la metodología de estudio con respecto a epidemia/pandemia requiere involucrar pensamiento complejo frente a los retos que denota esta situación. El objetivo de este estudio es validar un cuestionario de percepción y creencias dirigido a estudiantes de medicina y enfermería sobre el uso del cine ante la complejidad de un evento pandémico, con el propósito de potenciar las estrategias de enseñanza. Metodología: Se encuestó a 131 estudiantes. La evaluación de la confiabilidad se realizó a través del análisis de consistencia interna. La valoración de los 19 ítems se evaluó mediante análisis de correlación de Pearson y la validez de constructo mediante análisis factoria…
Synthesis, X-ray Structure, Antimicrobial and Anticancer Activity of a Novel [Ag(ethyl-3-quinolate)2(citrate)] Complex
2022
A novel Ag(I) citrate complex with ethyl-3-quinolate (Et3qu) was synthesized. Its structure was confirmed using X-ray single crystal to be [Ag(Et3qu)2(citrate)]. It crystallized in the Triclinic crystal system and P-1 space group with unit cell parameters of a = 8.6475(2) Å, b = 11.4426(3) Å, c = 15.2256(3) Å, α = 73.636(2)°, β = 79.692(2)° and γ = 86.832(2)°, while the unit cell volume was 1422.19(6) Å3. In the unit cell, there are two [Ag(Et3qu)2(citrate)] molecules and one unit as the asymmetric formula. The molecular structure comprised one Ag(I) coordinated with two Et3qu molecules via two almost equidistant Ag-N bonds and one citrate ion acting as a mono-negative monodentate ligand vi…

CCL5(RANTES) inhibits TGFbeta1 induced collagen production in human bronchial epithelial cells by action of Smad protein
2009
Airway epithelial cells modulate bronchial remodelling in COPD and asthma. TGF-β1 up-regulation was observed in the bronchial epithelial cells of asthmatics and COPD patients. TGF-β is involved in airways remodelling mainly acting via the Smad pathway. Increased CCL5 was also observed in bronchi of patients with severe COPD. We investigated the effects of TGF-β1 on collagen type I, Smad 3-4 and 7 expression and the effects of CCL5 on TGF-β1-induced collagen production in human bronchial epithelial cells (16HBE).Cells were treated with 10ng/ml of TGF-β1, 10ng/ml of CCL5 and 10ng/ml of both TGF-β1 and CCL5 for 0,3 and 24 hours.TGF-b1 increased Smad3,Smad4 and collagen type I(p=0.0472, p=0.043…
Golden Power, emergenza Covid-19 e spirito del tempo
2020
L’articolo ha ad oggetto l’ampliamento dei poteri speciali del Governo in materia di aziende strategiche (c.d. Golden Power), previsto dalle disposizioni introdotte dal d.l. 8 aprile 2020 n. 23, nell’ambito della produzione normativa legata all’emergenza Covid-19. Nel procedere ad una un’analisi del testo, il lavoro si interroga sul rapporto fra la nuova disciplina e le esigenze poste dalla pandemia, e con il più generale “spirito del tempo” in tema di protezione dei sistemi economici nazionali. The article refers to the enlargement of governmental special powers regarding strategic business entities (so called Golden Power), according to the new rules issued by decree 8 April 2020 n. 23, w…
The emission reduction potential of electric transport modes in Finland
2021
The transportation sector has become the fastest growing source of greenhouse gas (GHG) emissions. One solution to mitigate the impacts is a shift towards electric modes. Where previous studies have only focused on the replacement of individual modes, our study presents a more holistic approach by comparing land-based, water-based and airborne transportation modes. We study the GHG emission reduction potentials of electric cars, buses, trains, ferries and aircraft in comparison to existing modes on 34 routes within Finland and across the Baltic Sea to Sweden and Estonia. By comparing the GHG emissions in carbon dioxide equivalents (CO2-eq) per passenger kilometer for each mode, we also cons…
Learning Content Development With Social Tools: Learning Generated Content in Engineering
2013
The activities associated with learner generated content are supposed to enhance the learning process, facilitating the construction of knowledge. In this paper, the description of the process of creation of learning content is addressed. A group of students in the first year of an engineering degree collaboratively constructs a blog that covers the real-life applications of the physical concepts that are studied. We identify the characteristics that define meaningful learning during the development of the task and analyze the advantages and problems related to the use of Web 2.0 applications and Internet as learning tools.
Estados funcionales de los linfocitos Tgamma delta en sangre periférica en pacientes con cáncer de colon
2021
Estados funcionales de los linfocitos Tgamma delta en sangre periférica en pacientes con cáncer de colon ANTECEDENTES: El cáncer de colon es uno de los tumores más frecuentes y que más mortalidad causa a nivel mundial. Sabemos que el sistema inmune (SI) es uno de los principales reguladores en el desarrollo de las neoplasias y la capacidad de memoria de los linfocitos T es considerada crítica en la respuesta duradera frente al cáncer. Los linfocitos Tgamma delta son unos componentes singulares del SI que presentan amplia plasticidad fenotípica y funcional con respecto a los tumores pero, por el momento, se desconoce el papel que los Tgamma delta memoria juegan frente al cáncer. HIPÓTESIS: L…
Area-Based Depth Estimation for Monochromatic Feature-Sparse Orthographic Capture
2018
With the rapid development of light field technology, depth estimation has been highlighted as one of the critical problems in the field, and a number of approaches have been proposed to extract the depth of the scene. However, depth estimation by stereo matching becomes difficult and unreliable when the captured images lack both color and feature information. In this paper, we propose a scheme that extracts robust depth from monochromatic, feature-sparse scenes recorded in orthographic sub-aperture images. Unlike approaches which rely on the rich color and texture information across the sub-aperture views, our approach is based on depth from focus techniques. First, we superimpose shifted …
