...technique builds on pioneering work with mice done five years ago by César Milstein and Georges Köhler in Britain. By injecting foreign substances into the animals, they stimulated the production of antibodies against the invaders. Then they removed the animals' spleens, a major site for antibody production, and mixed the organ's antibody-producing cells with cancer cells. The result: hybrid cells, dubbed hybridomas, that inherited from the spleen the ability to produce antibodies and from the malignant cells the ability to replicate themselves indefinitely. These hybridomas produce identical copies of themselves-clones...
Shortly before takeoff, the freed Ambassadors of Venezuela, Israel, Egypt and the Dominican Republic descended the steps of the four-engine Soviet-built Ilyushin jetliner and were driven across the airfield in a speeding bus. One of them, Dominican Ambassador Diogenes Mallol, praised Colombian President Julio César Turbay Ayala for handling "this problem with prudence and calm," adding that "only in the beginning were we in danger because the terrorists were very nervous. Then everything calmed down." Another, Venezuelan Ambassador Virgilio Lovera, jubilantly told reporters: "I feel like running a mile in the Olympics...
...status, and to do so it needed to be painted by one of the lions of the medium, those astonishingly facile and brisk painters who plied their trade in the upper reaches of a society through which they moved on almost equal terms with their clients-Paul-César Helleu, Jacques-Émile Blanche, Anders Zorn.

Though a group of Colombian Congressmen also endorse the idea, most ranking officials remain opposed to the proposal. Colombian President Julio César Turbay Ayala sees "no possibility" of legalization. His feeling is shared by Attorney General Guillermo Gonzalez Charry, who is worried about marijuana's effect on the health of Colombian youth. By A.N.I.F.'S estimate, only 5% of the crop is smoked locally, and Gonzalez wishes to keep it that way. Captain Luis German Leon, head of the secret police narcotics unit, fears that if pot were legalized many people now involved in the marijuana...
Among Ramírez's books are a novel about a dictatorship in Central America called Do I Make You Afraid of Blood? and a biography of Augusto César Sandino. But Ramírez did not join the guerrillas who take their name from that Nicaraguan nationalist, who was slain in 1934 on the orders of the founder of the Somoza dynasty. Instead, with several priests, academics and businessmen, he founded the Group of Twelve, which sought to link the Sandinistas with less radical elements in the opposition to Tacho's government.
