Evaluación del efecto de Paecilomyces fumosoroseus y Trichoderma harzianum en la germinación y crecimiento de semillas de ajonjolí (Sesamum indicum).
(Universidad Santiago de Cali, 2024) Martínez García, Tania Isabella; Patiño Ramírez, Sebastián
Sesame has interesting nutritional properties with applications in the food, pharmaceutical or veterinary industries. In Colombia its cultivation is not widespread, being found mainly in the Caribbean. Excessive use of chemical fertilizers can increase production costs, thus negatively impacting soil quality. This has driven the search for sustainable alternatives, such as bioformulated ones using microorganisms to promote crop growth. In this study, the effect of the fungi Paecilomyces fumosoroseus and Trichoderma harzianum on the germination and growth of sesame under laboratory and nursery conditions was evaluated. It was evident that seeds inoculated with T. harzianum increased the speed and percentage of germination in the nursery, but no effects were observed with P. fumosoroseus. No significant effects were found on the agronomic variables (root length, stem and biomass). These results highlight the importance of continuing to investigate sustainable methods for agricultura
Secuelas Musculoesqueléticas en Pacientes con Antecedentes de COVID 19
(Universidad Santiago de Cali, 2023-05-30) Mendoza Guzmán,Diana Carolina; Zúñiga Jiménez , claudia Tatiana ( Directora)
The side effects generated by COVID-19 have become a public health concern in recent years, given the lack of knowledge about the disease of viral origin, its recent appearance and the same medical reports. The study of its effect on the different systems of the organism such as the muscular and skeletal, as well as others, to which potential side effects may extend, is key in combating the disease and guaranteeing the quality of life in patients. The report of multiple cases of patients who suffered from the disease, incidences and medical statistics are studied and analyzed. The existence of sequelae in multiple systems is determined, being the musculoskeletal one of the most affected, presenting loss of muscle mass and strength, fatigue, joint pain, among others. In addition, sequelae in the cardiac, neuronal and respiratory systems. Such effects can extend from weeks and months to more than a year. However, the relationship between the possible factors that can trigger the sequelae and/or extend their permanence is unknown, and some forms of prevention such as the vaccine are also questioned.
Elaboración de microcápsulas por gelación iónica, como agentes protectoras de probióticos a base de kéfir artesanal frente a condiciones ácidas

Probiotics are live microorganisms that, when consumed in adequate quantities, provide health benefits, interacting with the intestinal flora, helping to maintain an appropriate intestinal balance. However, probiotics can be sensitive to adverse environmental conditions, which is why microencapsulation techniques have been implemented to maintain their viability. The objective of this study is to evaluate the protective effect of the microencapsulation method. As? Using the ionic gelation technique with sodium alginate, calcium chloride and coating with carboxymethylcellulose (CMC), applying an in vitro simulation under gastric acid conditions. Regarding the methodology, the isolation of lactic acid bacteria was carried out using artisanal kefir, then biochemical tests were carried out to obtain a precise characterization of the probiotic strains acquired and finally microencapsulation was carried out by the ionic gelation method. The results demonstrated that the microencapsulated probiotic bacteria were resistant to in vitro simulation in gastric acid conditions, confirming that these bacteria were able to survive the acidic environment in which they were subjected, obtaining a higher concentration compared to free probiotic bacteria. In this way, it can be concluded that microcapsules with lactic acid bacteria obtained from artisanal kefir are a viable alternative
Actividad antimicrobiana de fitocannabinoides como principios activos en plantas medicinales: Una revisión sistemática
(Universidad Santiago de Cali, 2024) Rivera Vargas, Maria Yuliel; Suarez Osorio, Liseth; Falco Restrepo, Aura Dayana
Phytochemical compounds have long been an alternative to traditional medicine, which is why the industrial sector is dedicated to the manufacture of products such as drugs, cosmetics and veterinary products, and have considered innovating their lines from raw materials derived from the extraction of active compounds from plants. In this way, plant material with various attributes or substances that are allowed and regulated by government entities for use and marketing has been sought. Due to the above, it was proposed to carry out this systematic review that aims to identify medicinal plants that contain phytocannabinoids and that have antimicrobial activity. The consulted databases corresponding to 83, of which documents dating from the years 2010 to 2022 were found, however, 24 were discarded, since they were related to clinical aspects of veterinary use and others due to the years of publication, the which are outside the range of the minimum 10 years to be taken into account for the development of the systemic review
Obtención de carbón activado a partir de bagazo de caña para la descontaminación de tinidazol en aguas
(Universidad Santiago de Cali, 2024) Walteros Ospina, Melisa Andrea; Ciro Monsalve, Yhors Alexander; Rojas Camargo, John Jairo
Pollution of water sources is a major problem worldwide. Activated carbon produced from agroindustrial waste has been used for the removal of emerging contaminants that affect water bodies. To address this problem, it was proposed to obtain activated carbon from sugarcane bagasse for the decontamination of tinidazole in water, through the carbonization of the materials at different times and temperatures. A positive result was obtained with the physical and chemical activation of the bagasse; however, the highest percentage of removal was obtained through chemical activation with phosphoric acid with a result of 78% removal of tinidazole. In addition, analyzes of non-sterile pharmaceutical products were carried out in this case, neither Pseudomonas aeruginosa nor Staphylococcus aureus grew in any of the materials. These results demonstrated the adsorption capacity of bagasse, which can generate alternatives for a second use of agroindustrial waste and can be used as bioremediation elements
