Publicación Sólo datos Biotechnology, beginning with recombinant DNA toward a personalized medicine(Universidad de los Llanos, 2009-01-01) Verjan García, NoelI would like to initiate this document by making a brief description of the term Biotechnology, hoping to not hurt the feelings of many other professionals better versed than I, on the details of this science, as the application of traditional and/or scientific knowledge to manipulate microorganisms, cells or even higher organisms, directed to supply goods and services to the daily growing human population. With almost 30-year-old, biotechnology, driven by the ability to transplant a gene from one organism into another to introduce novel functionality in the receiving organism, has evolved to repro- gram cellular behavior or incorporate increasingly com- plex biosynthetic pathways (to produce novel metabolic products or to achieve greater system integration) or genetic regulatory constructs (to modulate the activity of recombinant genes in space and time) (Bhalerao, 2009). Biotechnology one of the riskiest industries has achieved a dynamic growth and unparalleled discovery, outstanding advances and contributions to human and animal medicine. This has mainly been possible throughout the exploration of diverse unicellular and multicellular genomes, the genes and the proteins they encode, and together with the development of dozens of technologies, reach every day a better understand- ing of cell biology, homeostasis and disease. Thus, biotechnology has established as an industry, where any bio-product can be patentable.Publicación Sólo datos Caracterización fitoquímica y bromatológica de Dichapetalum spruceanum vell.affinis planta silvestre de la Orinoquia Colombiana y sus potencialidades de uso(Universidad de los Llanos, 2010-12-01) Cortés-Castillo, Caroll E.; Quiñones-Méndez, Luz M.; Hernández C, CatalinaTitulo en ingles: Phytochemical and Bromatologic characterization of Dichapetalum spruceanumvell.affinis silvester plant of the Colombian Orinoquia and use potentiality.RESUMEN: Dichapetalum spruceanum vell.affinis (DICHAPETALACEAE), es una especie espontánea del departamento del Casanare en la Orinoquia Colombiana, la cual ha sido poco estudiada y considerada una maleza para los cultivos que se desarrollan en esa zona; dentro del marco del proyecto Caracterización fitoquímica y bromatológica de Dichapetalum spruceanum, planta silvestre subexplotada de la Orinoquia Colombiana, financiado por el Instituto de Investigaciones de la Orinoquia Colombiana (IIOC), se desarrollo un estudio acerca de la composición fitoquímica y bromatológica de la raíz o xilopodio con miras a determinar su potencialidad de uso, teniendo en cuenta su amplia distribución y su gran tamaño másico (12kg promedio). Esta especie está asociada a suelos húmedos ubicados en terrazas medias y bajas y en zonas de vega principalmente; dentro de los metabolitos secundarios característicos se encontraron alcaloides, compuestos cardiotónicos y cumarinas, así como su alto contenido de nutrientes digestibles totales (87,65 %), que sumado a los resultados del análisis bromatológico permiten vislumbrar la potencialidad que esta especie tiene como recurso para biocombustibles y para alimentación animal.Palabras clave: Recurso florístico, Orinoquía, fitoquímica, bromatología, metabolitos secundarios.ABSTRACT: Dichapetalum cf. spruceanum (DICHAPETALACEAE), is a spontaneous specie of Casanare department at colombian Orinoquia, which has been few studied and it has been considered weeds in the crops developed in this area; in the frame of project Characterization phytochemical and bromatologic of Dichapetalum cf. spruceanum wild plant underexploited at colombian Orinoquia, sponsor for Instituto de Investigaciones de la Orinoquia Colombiana (IIOC), was developed a study about phytochemical and bromatologic composition of root to determine its use potentiality, having on count its wide distribution and big mass size (12kg average). Was found that this specimen is associated to humid soils placed in middle and lower terraces and floodplains mainly; within the characteristic secondary metabolites were found alkaloids, cardiotonics compounds and cumarines, as well as, a high content of total digestible nutrients (87.65 %), added to the other results of bromatologic analysis allowed to think in the potentiality that this plant has as biofuel and animal feeding resource.Key Words: Floristic resource, Orinoquia, phytochemical, bromatology, secondary metabolites
