El cigarrillo electrónico en la deshabituación tabáquica: una revisión bibliográfica
Introducción: Actualmente, el tabaco es el principal responsable de numerosas enfermedades y muertes en el mundo. Los programas de deshabituación tabáquica cuentan, hoy en día, con varias vías de abordaje. Últimamente se ... -
Etapas de cambio comportamental frente al consumo de sustancias psicoactivas en escolares de 9 a 17 años de Bogotá D.C., Colombia
Introducción. El consumo de sustancias psicoactivas (SPA) es una problemática que afecta a estudiantes desde edades tempranas. Objetivo. Describir las etapas de cambio de comportamiento frente al consumo de SPA en escolares ... -
Functional improvement of human cardiotrophin 1 produced in tobacco chloroplasts by co-expression with plastid thioredoxin m
Human cardiotrophin 1 (CT1), a cytokine with excellent therapeutic potential, was previously expressed in tobacco chloroplasts. However, the growth conditions required to reach the highest expression levels resulted in an ... -
Heat treatment alleviates the growth and photosynthetic impairment of transplastomic plants expressing Leishmania infantum Hsp83-Toxoplasma gondii SAG1 fusion protein
Previously, we showed that transplastomic tobacco plants expressing the LiHsp83-SAG1 fusion protein displayed a chlorotic phenotype and growth retardation, while plants expressing the SAG1 and GRA4 antigens alone did not. ... -
High-density seedling expression system for the production of bioactive human cardiotrophin-1, a potential therapeutic cytokine, in transgenic tobacco chloroplasts
Histidine‐tagged human cardiotrophin‐1 (hCT‐1), a recently discovered cytokine with excellent therapeutic potential, was expressed in tobacco chloroplasts under the transcriptional and translational control of two different ... -
Human papillomavirus L1 protein expressed in tobacco chloroplasts self-assembles into virus-like particles that are highly immunogenic
Cervical cancer is the second most prevalent cancer in women worldwide. It is linked to infection with human papillomavirus (HPV). As the virus cannot be propagated in culture, vaccines based on virus‐like particles have ... -
Increased bioethanol production from commercial tobacco cultivars overexpressing thioredoxin f grown under field conditions
Bioethanol is mainly produced from food crops such as sugar cane and maize while it has been held partly responsible for the rise of food commodity prices. Tobacco, integrated in biorefinery facilities for the extraction ... -
Overexpression of plastidial thioredoxin f leads to enhanced starch accumulation in tobacco leaves
Starch, the most abundant storage carbohydrate in plants, has been a major feedstock for first‐generation biofuels. Growing fuel demands require, however, that the starch yields of energy crops be improved. Leaf starch is ... -
Overexpression of plastidial thioredoxins f and m differentially alters photosynthetic activity and response to oxidative stress in tobacco plants
Plants display a remarkable diversity of thioredoxins (Trxs), reductases controlling the thiol redox status of proteins. The physiological function of many of them remains elusive, particularly for plastidial Trxs f and ... -
Physiological performance of transplastomic tobacco plants overexpressing aquaporin AQP1 in chloroplast membranes
The leaf mesophyll CO2 conductance and the concentration of CO2 within the chloroplast are major factors affecting photosynthetic performance. Previous studies have shown that the aquaporin NtAQP1 (which localizes to the ... -
Prevalencia de actividad física y su relación con variables sociodemográficas y estilos de vida en la población de 18 a 65 años de Pamplona
Fundamento: los conocimientos actuales permiten considerar que existe una asociación de tipo causal entre el nivel de actividad física y la aparición de diversas enfermedades. A pesar de ello, la actividad física es una ... -
Tobacco plastidial thioredoxins as modulators of recombinant protein production in transgenic chloroplasts
Thioredoxins (Trxs) are small ubiquitous disulphide proteins widely known to enhance expression and solubility of recombinant proteins in microbial expression systems. Given the common evolutionary heritage of chloroplasts ... -
Whole exome sequencing characterization of individuals presenting extreme phenotypes of high and low risk of developing tobacco-induced lung adenocarcinoma
Background: tobacco is the main risk factor for developing lung cancer. Yet, some heavy smokers do not develop lung cancer at advanced ages while others develop it at young ages. Here, we assess for the first time the ...
