  • Publication number: 20110308477
    Abstract: A dog tug apparatus includes a housing having a dispensing portion and a tug device configured to extend from and retract back into the housing. The tug device includes a tug having teeth scrubbing bristles extending there from. A resistance assembly resists unwinding of the tug line, and includes first and second opposing electromagnets suspended about the periphery of a slotted metal disk. A controller can adjust the resistance applied by the resistance assembly and provide an audible signal at the end of an exercise event. A recovery mechanism provides a means for rewinding the tug line about the spool after the tug line has been unwound, such as during a dog exercise event. In use, the rotation of the spool in the direction to unwind the tug line rotates a reduction gear system and results in the rotation of a treat dispensing mechanism to dispense a dog treat.

  • Publication number: 20110009344
    Abstract: The invention relates to the field of drug development against acute radiation injury caused by exposure to high-energy electromagnetic waves (X-rays, gamma rays) or particles (alpha particles, beta particles, neutrons). To date, there is no effective drug to ameliorate radiation injury after accidental exposure to ionizing irradiation. The invention provides a method of treating radiation injury of a subject in need thereof comprising administering to the subject a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids. Furthermore, the invention provides use of a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids for the production of a pharmaceutical composition for the treatment of a subject suffering from or believed to be suffering from radiation injury. In particular, the invention provides anti-radiation peptides having a dose reduction factor (DRF) against acute gamma irradiation of at least 1.
