Ítem Acumulación de selenio intracelular en Scenedesmus obliquus(Universidad EAFIT, 2020) Guzmán Góez, Mateo; Cardona Arias, Juan Pablo; Sáez Vega, Álex ArmandoÍtem Analysis of TYK2 P1104A variant in a cohort of colombian patients with pulmonary tuberculosis(Universidad EAFIT, 2020) Guzmán Zuluaga, Laura Cristina; Arias Sierra, Andrés Augusto; Barrera Robledo, Luis FernandoTuberculosis continues to be one of the main causes of death worldwide with around 10 million people infected annually, which is a direct problem for public health. Data that has accumulated over decades suggests that variability in human susceptibility to tuberculosis disease has a strong genetic component. Both primary and acquired immunodeficiencies (PID) are strongly related to broad infectious phenotypes that include the full range of diseases caused by the infectious agent Mycobacterium tuberculosis. Recently it was found that a PID found in up to 1/600 individuals of European descent, in fact a variant was found that affects the catalytic activity of TYK2 therefore selectively alters the immunity to IFN-g mediated by IL-23 while the responses to IL-10, IL-12, and IFN-a / b are intact. These PIDs are only expressed symptomatically after exposure to Mycobacterium tuberculosis. However, we hypothesize that homozygous for the P1104A variant or compound heterozygosity in this same TYK2 gene can confer a selective response, thus predisposing to TB. This study intends to 1. Identify the variant P1104A of the TYK2 gene in Colombian patients with pulmonary tuberculosis, 2. Identify other rare or common variants in the TYK2 gene in patients with pulmonary tuberculosis, 3. Correlating data from the Colombian population with what has been found in other populations.Ítem Antagonismo de microorganismos aislados a partir de la borra de café, generada en la Universidad EAFIT, sobre el crecimiento del hongo Pleurotus sp.(Universidad EAFIT, 2021) Caro Miranda, Vanesa; Jaramillo Mazo, Claudia YulietÍtem Capacidad metabólica de cepas aisladas de la microbiota intestinal de mujeres gestantes y en período de lactancia para asimilar fuentes nutricionales ricas en colina : hacia el desarrollo de bioterapéuticos microbianos funcionales(Universidad EAFIT, 2022) Blel Jubiz, Shadia María; Quintero Rojas, María Isabel; Gómez Mesa, Laura; Sierra Zapata, LauraÍtem Captura de material particulado 1, 2.5 y 10 micras, con el uso de microalgas en fotobiorreactores exteriores(Universidad EAFIT, 2020) Mazo Zapata, Santiago; Miranda Parra, Alejandra María; Miranda Parra, Alejandra MaríaParticulate matter (PM), made up of a variety of organic and inorganic substances, is found to be harmful to human health. Due to its small size, this combination of substances can enter the body by the respiratory route and cause all kinds of related diseases, such as lung cancer, trachea, esophagus. In addition to this, the 1 micron particles can enter the circulatory system and cause associated problems such as stroke and cardiovascular damage. As a result of this, especially in the mainly affected cities, such as Medellín, they will come looking for methods to deal with this problem, suggesting the use of cutting-edge technology to try to largely solve PM contamination, however, the contributions that are They have made an impact on closed spaces, without identifying that they can be very expensive to maintain, on the other hand, a level outside the city or in outdoor conditions. The use of technology has been very low, and containment measures translate into social and mobility strategies such as spike and plate extension. In this study, the use of technology in outdoor conditions is proposed, through the use of photobioreactors and microalgae to evaluate the capture potential that these microorganisms have in the capture of this PM and how it is possible to extrapolate it as a future solution to use it in The city of Medellín. As a conclusion of the experiment, it was found that the Scenedesmus Obliquus ATCC 457 microalgae (S. Obliquss ATCC 457) could grow up to 1.52 g / L and retain up to 61.07% of PM 1, 65.45% of PM 2.5 and 87.01% of PM 10.Ítem Caracterización de la epidemiología de Moniliophthora roreri, hongo fitopatógeno del cacao(Universidad EAFIT, 2021) Jiménez Zapata, Diana Lorena; Mosquera López, Sandra; Correa Álvarez, JavierÍtem Caracterización de los microorganismos asociados con el daño de la lenticela en Persea americana cv.

Its production, like that of most agricultural products, is affected by the emergence of diseases caused by microorganisms, generating significant losses in production. Natural extracts with antimicrobial activity are considered an alternative to control the emergence of these diseases. The purpose of this work was the identification of a microorganism isolated from the diseased tamarillo and the evaluation of the antimicrobial activity on this of extracts obtained from mint, oregano, papaya seeds and orange peel. The extracts were obtained; using hydrodistillation and the Soxhlet extraction method. By the first method, only the oily phase could be extracted from the orange peel; for the rest of the materials, aqueous extracts were obtained. While by Soxhlet the oily phase of mint, oregano and papaya seeds was recovered. The microorganism that was isolated was identified in the company AOXLAB as Colletotrichum acutatum and the minimum inhibitory capacity of the extracts obtained on it was evaluated. This allowed determining that the oily extract of the papaya seeds was the only one capable of inhibiting the fungus with a concentration of 1250 mg/L. The oily papaya extract was subsequently nanoencapsulated in niosomes in order to compare its encapsulated and unencapsulated antimicrobial potential. This test allowed finding that the encapsulation process reduces the required minimum inhibition concentration to 78.13 mg/L.Ítem Efecto de diferentes fertilizantes comerciales en el crecimiento y porcentaje de nitrógeno de dos especies de microalgas(Universidad EAFIT, 2020) Sánchez Ortiz, Aura Cristina; Miranda Parra, Alejandra MaríaÍtem Efecto de la concentración de nitrógeno en la producción de Spirulina sp. en un proceso bistage(Universidad EAFIT, 2020) Ramírez Zuluaga, Maria Camila; Peña Ospina, Maria Isabel; Sáez Vega, Alex ArmandoÍtem Efecto de la inoculación bacteriana a nivel radicular sobre el crecimiento y la sanidad de plantas de banano(Universidad EAFIT, 2020) Restrepo Gutiérrez, Susana; García Giraldo, Gisell Adriana; Villegas Escobar, ValeskaÍtem Evaluación de bacterias cadmio tolerantes aisladas a partir de suelos provenientes de una finca cacaotera del Urabá antioqueño(Universidad EAFIT, 2021) Tovar Vélez, Valentina; Jaramillo Mazo, Claudia; Correa Álvarez, Javier; Jaramillo Mazo, Claudia.; Correa Álvarez, Javier
