...that one person who claimed to be the inventor of the television is Russian emigre Vladimir Zworykin? In 1929 David Sarnoff, founder of RCA, asked Zworykin what it would take to develop TV for commercial use. He said: a year and a half and $100,000. In reality, it took 20 years and $50 million! Before his death in 1982 at the age of 92, Zworykin said of his invention: "The technique is wonderful. It is beyond my expectations. But the programs! I would never let my children even come close to this thing."

AbstractA DNA vaccine effective for inhibiting endothelial cell proliferation comprises a DNA construct operably encoding a vascular endothelial growth factor (VEGF) receptor protein. This invention provides DNA vaccines that encode VEGF receptor-2 (KDR, SEQ ID NO: 2), VEGF receptor-1 (Flt-1, (SEQ ID NO: 4), or Flk-1 (the murine homolog of KDR, SEQ ID NO: 6), DNA sequences SEQ ID NOS: 1, 3, and 5 respectively, as well as methods of using such a DNA vaccine to inhibit vascular endothelial cell proliferation in the tumor micro-environment. Anti-angiogenesis and subsequent decrease in tumor growth and dissemination is achieved.Other References
