  • Method for detecting and killing epithelial cancer cells
    Patent number: 6649144
    Abstract: A diagnostic method for detecting cancerous epithelial cells by selectively marking the mitochondria of the cancer cells, by delivering to the epithelium a cationic supravital mitochondrial marking agent. Selective killing of cancerous epithelial cells in the presence of normal cells is effected by delivering a cationic supravital mitochondrial marking agent to epithelial cancer cells. The killing agent can also comprise the reaction product of the marking agent and a cancer chemotherapeutic drug.

  • Method for detecting and diagnosing epithelial cancer
    Patent number: 6459920
    Abstract: A method for detecting epithelial cancer includes generating a real-time video image of the locus of potential cancerous sites on the epithelium. The real-time video image is displayed on a television monitor screen. The real-time video image on the monitor is examined to locate suspected cancerous sites and the results of such examination are recorded.

  • Livestock handling system and apparatus therefor
    Patent number: 4365591
    Abstract: Apparatus for handling small livestock such as chickens comprising open topped slideable drawers (12) in a rectangular housing (10) from which they are slid to allow for loading and subsequently for unloading onto a transfer conveyor (20). A roof (34) over the conveyor covers the open tops of the drawers as they move therealong to prevent the livestock from escape.An elevating platform (28) adjacent the conveyor (20) allows the housing (10) to be raised and lowered to allow the drawers to be pushed or pulled from the housing directly onto the conveyor.A method of collecting and handling livestock involves the step of filling the drawers in the housing with livestock, transporting the housing to a drawer unloading station where the drawers are removed from the housing onto a conveyor, for movement therealong beneath a roof which serves to cover the open tops of the drawers to prevent the livestock escaping, while they are transferred to a livestock unloading station at which the roof terminates.
