...into the air supply,” he said. Another application of SP technology is the bioimaging of infectious organisms. In a collaborative effort among members of Harvard Medical School and Draper Laboratory, scientists are developing SP technology that would enable researchers to detect the movement of a single poliovirus through an artificial cell membrane. The new technology could act as a vaccine development tool, said Dale N. Larson, Harvard Medical School Director of the Technology and Engineering Center. The new system would make the production of new drugs cheaper and more effective by allowing researchers and pharmaceutical companies...
...time--and a very bad place--to halt vaccines. There are now 35 million Nigerian kids under age 5, and 20% have no polio vaccinations. Says Oliver Rosenbauer, spokesman for WHO's Global Polio Eradication Initiative: "That's a lot of breathing space for the poliovirus to survive...
...emerged are getting intensive attention too. In Nigeria there are six nationwide rounds of vaccinations scheduled for 2005. In other countries, such as Yemen, Egypt and India, the immunization program is getting a boost from a so-called monovalent vaccine, which more effectively knocks out the Type 1 poliovirus circulating in those areas. But even the best immunization campaign will leave a lot of poliovirus at large, at least for a while. WHO and other groups still hope to eradicate the disease this year in India, Pakistan and Afghanistan, where polio was endemic before the current outbreaks and good vaccination...
Roosevelt's optimism about medical research seems, in retrospect, amazing. Doctors could not prevent or treat the poliovirus infection that had paralyzed him nearly twenty years earlier. John Franklin Enders and vaccines were still in the future; the main therapies were iron lungs and warm baths. Most of the staples of modern medicine were also still unknown. Antibiotics. Hormone replacements. Effective drug therapies for psychotic illnesses. Pre-natal testing. Coronary bypass surgery and artifical joints. Also in the future were medications that could have lowered FDR's blood pressure and perhaps forestalled the stroke that killed him less than five...
...discovery cannot directly explain the cases of the San Francisco 49ers or the Ohio schoolteachers, it does lend credence to the notion that something toxic in diet or environment can later trigger ALS. Indeed, over the years, a befuddling array of culprits has been suggested. They include infection with poliovirus, exposure to heavy metals, employment in the plastics industry and a history of traumatic injuries...
