Estudio fitoquímico de hojas, flores y frutos de Bejaria resinosa Mutis ex Linné filius (Ericaceae) y evaluación de su actividad Antiinflamatoria

El presente trabajo de investigación describe los resultados del estudio fitoquímico y biológico realizado con los extractos de éter de petróleo y etanólicos de hojas, flores y frutos de la especie vegetal Bejaria resinosa (Ericaceae) clasificada en el Herbario Nacional Colombiano bajo el número de colección COL 565500 con el propósito de contribuir a las investigaciones realizadas a la familia Ericaceae ya que esta especie no cuenta con estudios recientes.Magíster en Ciencias BiológicasMaestrí

Triterpenos y Esteroles de Salvia Leucantha (Lamiaceae) y Evaluación de su Capacidad Antioxidante

Con el fin de contribuir en el conocimiento de la flora Colombiana, particularmente aquella presente en la región del Guavio, se eligió la especie Salvia leucantha para realizar un estudio fitoquímico preliminar de su composición química y bioactividad a nivel antioxidante. Para ello se realizó el análisis fitoquímico preliminar de hojas y se evaluó la presencia de los principales grupos de metabolitos secundarios, cuyas estructuras fueron analizadas tentativamente por CG-EM y respectiva comparación con las bases de datos NIST-08, adicionalmente se evaluó la actividad antioxidante de extractos y fracciones por DPPH. Se de­tectó la presencia de triterpenos pentaciclicos en gran concentración, lo cual era de esperarse al tratarse de una especie del género Salvia, ampliamente conocida por su contenido de terpenos y amplia gama de aceites esenciales. Estos compuestos son ampliamente utilizados en la industria alimenticia, cosmética y farmacéutica por sus propiedades físico-químicas y farmacológicas, pero no reportan porcentajes de inhibición altos para poderlos catalogar como antioxidantes fuertes. Los resultados de este trabajo son importantes como primera aproximación a la ampliación del conocimiento químico y a la posible utilidad de las especies presentes en esta zona de Colombia con características agronómicas óptimas para el es­tablecimiento de cultivos, que permitan una utilización racional de los recursos naturales de nuestro país, como fuente de desarrollo regional y nacional

Estudio fitoquímico y screening de la actividad biológica de las especies Conyza trihecatactis y Ageratina vacciniaefolia

Este trabajo se desarrolló teniendo en cuenta dos aspectos fundamentales: químico y biológico. El aspecto químico involucró procesos de extracción, fraccionamiento, aislamiento y purificación de los metabolitos secundarios presentes en las partes aéreas de las especies vegetales estudiadas; y en el aspecto biológico, los extractos etanólicos completos y las fracciones obtenidas se les evaluó la actividad antiinflamatoria (método de inducción de inflamación con -carragenina), la actividad citotóxica (método del MTT), la capacidad antioxidante (método del DPPH) con cuantificación de fenoles (método Folin-Ciocaulteu) y la toxicidad aguda en Artemia salina.Magíster en Ciencias BiológicasMaestrí

World Development Report 2024 : The Middle-Income Trap

Middle-income countries are in a race against time. Many of them have done well since the 1990s to escape low-income levels and eradicate extreme poverty, leading to the perception that the last three decades have been great for development. But the ambition of the more than 100 economies with incomes per capita between US$1,100 and US$14,000 is to reach high-income status within the next generation. When assessed against this goal, their record is discouraging. Since the 1970s, income per capita in the median middle-income country has stagnated at less than a tenth of the US level. With aging populations, growing protectionism, and escalating pressures to speed up the energy transition, today’s middle-income economies face ever more daunting odds. To become advanced economies despite the growing headwinds, they will have to make miracles. Drawing on the development experience and advances in economic analysis since the 1950s, World Development Report 2024 identifies pathways for developing economies to avoid the “middle-income trap.” It points to the need for not one but two transitions for those at the middle-income level: the first from investment to infusion and the second from infusion to innovation. Governments in lower-middle-income countries must drop the habit of repeating the same investment-driven strategies and work instead to infuse modern technologies and successful business processes from around the world into their economies. This requires reshaping large swaths of those economies into globally competitive suppliers of goods and services. Upper-middle-income countries that have mastered infusion can accelerate the shift to innovation—not just borrowing ideas from the global frontiers of technology but also beginning to push the frontiers outward. This requires restructuring enterprise, work, and energy use once again, with an even greater emphasis on economic freedom, social mobility, and political contestability. Neither transition is automatic. The handful of economies that made speedy transitions from middle- to high-income status have encouraged enterprise by disciplining powerful incumbents, developed talent by rewarding merit, and capitalized on crises to alter policies and institutions that no longer suit the purposes they were once designed to serve. Today’s middle-income countries will have to do the same

How to Achieve Inclusive Growth

Rising inequality and widespread poverty, social unrest and polarization, gender and ethnic disparities, declining social mobility, economic fragility, unbalanced growth due to technology and globalization, and existential danger from climate change are urgent global concerns of our day. These issues are intertwined. They therefore require a holistic framework to examine their interplay and bring the various strands together. This book brings together leading academic economists and experts from several international institutions to explain the sources and scale of these challenges. The book summarizes a wide array of empirical evidence and country experiences, lays out practical policy solutions, and devises a comprehensive and unified plan of action for combatting these economic and social disparities. This authoritative book is accessible to policy makers, students, and the general public interested in how to craft a brighter future by building a sustainable, green, and inclusive society in the years ahead
