...immediate obstacle to translating the results to human cells involves the way that the scientists turned back time on the mouse skin cells. They used a retrovirus vector, piggybacking the genes for the growth factors and proteins onto this infectious ferry. Retroviruses, however, like HIV, can cause infectious diseases and are not always easy to control, so before testing this approach in humans, researchers need to find other modes of transport for the critical compounds. The good news is that they need the genes to churn out their proteins for a only brief period of time, so using less virulent...
...might seem that after the threats of bioterrorism, and after the spread of HIV and SARS in recent decades, public health officials would be better prepared - and more coordinated - when it comes to dealing with nasty bugs that hitch rides from country to country in often unsuspecting plane travelers. But this latest TB scare illustrates that the system still has a long way to go to be able to deal effectively with such health crises...
...used to traveling around the U.S. and the world speaking to teenagers in well-appointed high school auditoriums, he was forced to be resourceful on Roatan, where the municipal hospital has no running water and many of the Hispanic and Afro-Caribbean residents believe that they can get HIV by stepping on a chicken bone that has a hex on it. "It was totally heartbreaking when I first came here, and talked to teenagers who have HIV," says Fried, a former Broadway actor who has been living with the virus for nearly twenty years and has seen 134 friends...
...HIV began to spread rapidly on Roatan after Hurricane Mitch in October 1998, when thousands of mainland Hondurans, left homeless and destitute by the storm, moved to Roatan seeking jobs in the tourism and development boom. Unable to find even the most menial employment because they could only speak Spanish (islanders speak both English and Spanish on Roatan), many turned to prostitution, fueling an already burgeoning rate of infection...
...name is Scott Fried, I live in New York City, and this is what HIV looks like on a man,"? said Fried, addressing his audience - two young mothers breast-feeding their infants and a group of young toughs in stiff new blue jeans chain-smoking cigarettes. He reassured them that you can't get AIDS from touching someone who is infected or breathing the air after they sneeze, and you can't get AIDS from a child who is infected with HIV. Fried, who is gay, also told them what it had been like to tell his conservative Jewish parents...
