6. El Paclitaxel o Taxol ® es un medicamento útil en el tratamiento del cáncer. Fue descubierto en lnstituto de Investigación Triángulo (Research Triangle Institute, RTI) en 1967. Monroe Wall y Mansukh Wani aislaron el compuesto en la corteza de la tuja (‘tuya’) del pacífico e identificaron la actividad antitumoral en una variedad de tumores en roedores y para 1970 determinaron la estructura química del paclitaxel.
7. Este compuesto se ha empleado efectivamente en el tratamiento de pacientes con cáncer de plumón, ovario y seno, y en formas avanzadas del sarcoma de Kaposi (Saville et al., 1995). La sustancia también se ha empleado para prevenir la restenosis, que es el angostamiento recurrente de los ‘stents’ coronarios. Cuando se aplica localmente en las coronarias la cubierta de paclitaxel limita el crecimiento de la neoíntima, o tejido de cicatrización dentro de los stents (Heldman et al. 2001)
8. The history of paclitaxel begins with a 1958 National Cancer Institute study that commissioned Department of Agriculture botanists to collect samples of over 30,000 plants to test for anticancer properties. Arthur S. Barclay, one of those botanists, collected 15 lbs of twigs, needles, and bark from Pacific yew trees in a forest near Mount St. Helens. Months later, in 1963, Monroe E. Wall discovered that bark extract from the Pacific yew possessed antitumor qualities, beginning to reveal the tree's hidden treasure.
9. Soon after, Wall and his colleague Mansukh C. Wani were busy isolating and purifying plant compounds for anticancer tests in Research Triangle Park, North Carolina. In 1967 the team had isolated the active ingredient, announcing their findings at an American Chemical Society meeting in Miami Beach. Wall and Wani published their results, including the chemical structure, in a 1971 issue of the Journal of the American Chemical Society .
20. In many tropical countries, the majority of deforestation results from the actions of poor subsistence cultivators. However, in Brazil only about one-third of recent deforestation can be linked to "shifted" cultivators. A large portion of deforestation in Brazil can be attributed to land clearing for pastureland by commercial and speculative interests , misguided government policies, inappropriate World Bank projects, and commercial exploitation of forest resources. For effective action it is imperative that these issues be addressed. Focusing solely on the promotion of sustainable use by local people would neglect the most important forces behind deforestation in Brazil. Source: The Wikipedia The Forest The Cattle
21. DEFORESTATION IN BRAZIL : 60-70 percent of deforestation in the Amazon results from cattle ranches while the rest mostly results from small-scale subsistence agriculture . Despite the widespread press attention, large-scale farming (i.e. soybeans ) currently contributes relatively little to total deforestation in the Amazon. Most soybean cultivation takes place outside the rainforest in the neighboring cerrado grassland ecosystem and in areas that have already been cleared. Logging results in forest degradation but rarely direct deforestation. Studies have showed a close correlation between logging and future clearing for settlement and farming.
