Bienvenidos a ¡Adelante!, el programa que los pone al día con las novedades de la ciencia y la tecnología. Yo soy Laura Rissetto y tenemos en el estudio hoy al señor Marcelo Criscuolo, el director ejecutivo de BioSidus, que es una empresa de biotecnología aquí en Argentina. Durante los últimos años, BioSidus ha hecho espectaculares avances en la clonación y hoy el señor Criscuolo nos va a informar sobre algunos de sus logros. ¡Adelante, señor Criscuolo! ¡Bienvenido!
—Gracias. Es un placer estar aquí.
—Bueno, señor Criscuolo, en el año 2002 su empresa logró la primera clonación de vacas en Latinoamérica con el nacimiento de la vaca llamada Pampa. Y luego en el 2003 lograron que otra vaca clon produjera en su leche la hormona de crecimiento humana. ¿Podría explicarnos el objetivo y la importancia de este trabajo?
—Sí, claro. Es un logro científico y tecnológico, pero a la vez es algo que va a mejorar la calidad de vida para muchas personas en Argentina y en el mundo.
—¿Y cómo?
—Pues, en BioSidus hace muchos años que fabricamos la hormona de crecimiento humana para producir un medicamento que ayuda a los niños que sufren de enanismo.
—¿Los niños de baja estatura que no crecen normalmente?
—Sí. Y como el costo de producir esta hormona en nuestros laboratorios era alto, el precio del medicamento que fabricamos también era muy alto. Pero, usando las técnicas de clonación y con genes humanos logramos producir la hormona en cantidades más grandes y así reducimos el costo del medicamento un 50%.

Levi Coffin’s Reminiscences of the Underground Railroad in the 1850s I was personally acquainted with all the active and reliable workers on the Underground Railroad in the city, both colored and white. There were a few wise and careful managers among the colored people, but it was not safe to trust all of them with the affairs of our work. Most of them were too careless, and a few were unworthy—they 1 could be bribed by the slave hunters to betray the hiding places of the fugitives. We soon found it to be the best policy to confine our affairs to a few persons and to let the whereabouts of the slaves be known to as few as possible. When slave hunters were prowling around the city we found it necessary to use every precaution. We were soon fully initiated into the management of Underground Railroad matters in Cincinnati, and did not lack for work. Our willingness to aid the slaves was soon known, and hardly a fugitive came to the city without applying to us for assistance. 2 There seemed to be a continual increase of runaways, and such was the vigilance of the pursuers that I was obliged to devote a large share of time from my business to making arrangements for their concealment and safe conveyance of the fugitives. They sometimes came to our door frightened and panting and in a destitute condition, having fled in such haste and fear that they had no time to bring any clothing except what they had on, and that was often very scant. The expense of providing suitable clothing for 3 them when it was necessary for them to go on immediately, or of feeding them when they were obliged to be concealed for days or weeks, was very heavy…. Our house was large and well adapted for secreting fugitives. Very often slaves would lie concealed in upper chambers for weeks without the boarders or frequent visitors at the 4 house knowing anything about it. My wife had a quiet unconcerned way of going about her work as if nothing unusual was on hand, which was calculated to lull every suspicion of those who might be watching, and who would have been at once aroused by any sign of secrecy or mystery. Even the intimate friends of the family did not know when there were slaves hidden in the house…. a. life sciences. b. physical sciences. c. social sciences and history. d. career fields.
