DIED. JOHN FRANKENHEIMER, 72, acute director of social dramas and political thrillers; after spinal surgery; in Los Angeles. A force in TV and movies for nearly half a century, he directed 42 Playhouse 90 shows (including Days of Wine and Roses) before turning to feature films. In 1962 he made Birdman of Alcatraz and The Manchurian Candidate, template for the modern paranoid conspiracy tragicomedy. Seven Days in May and Seconds painted bleak portraits of an America at war with its best instincts. He sagged personally and professionally after the death of Robert Kennedy, whom he drove to the candidate...
...This is precisely what the advocates of research cloning are promising. Clone, grow it and then use the cloned tissue to create near identical replacement parts for the original animal and thus presumably put us on the road to curing such human scourges as Alzheimer's disease, Parkinson's, spinal-cord injuries and the like...
...stem cells alive, growing one generation after another while retaining their pluripotentiality (their ability to develop into all different kinds of cells). Then you have to take those stem cells and chemically tweak them in complex ways to make them grow into specialized tissue cells--say, neurons for a spinal-cord injury. Then you inject the neurons into the patient and get your cure...
Radio technology and medical know-how came together most dramatically in April 2000. Pirates had boarded the sailboat of a Dutch family off the coast of Honduras and had shot a 13-year-old boy who was aboard. His injuries were so severe that the bullet severed his spinal cord and paralyzed...
Paralysis results from neck and spinal cord injuries because the neural traffic that moves between the brain and the muscles is severed or blocked. Like a kink in a garden hose, spinal trauma cuts off the flow of information that travels along afferent nerves, which send signals from the body to the brain, and efferent nerves, which carry instructions from the brain to the body's musculature. In many cases of paralysis, though, the motor and sensory nerves below the level of the lesion remain intact and could function again...
