  • Patent number: 9138495
    Abstract: The present invention relates to bifunctional compounds, the bifunctional compounds for use in molecular imaging and therapy, methods of molecular imaging using the bifunctional compounds and kits including the bifunctional compounds for use molecular imaging. The bifunctional compounds have a tripodal hydroxypyridinone chelating portion and may be conjugated to a targeting group so that the compounds target specific cells or tissues in a subject.
    Type: Grant

  • Publication number: 20130157375
    Abstract: In one aspect, there is provided a fluorescent iron-binding compound bound to a solid phase. Also provided is a method for detecting non-transferrin bound iron in a sample, comprising contacting the sample with a fluorescent iron-binding compound bound to a solid phase and detecting a fluorescent signal derived from the fluorescent iron-binding compound bound to the solid phase, wherein the fluorescent signal is indicative of non-transferrin bound iron levels in the sample. Further provided is use of a fluorescent iron-binding compound bound to a solid phase to detect non-transferrin bound iron in a sample.

  • Patent number: 8046134
    Abstract: A steering system for a machine having at least one steerable traction device is disclosed. The steering system may have a steering actuator operatively connected to the at least one steerable traction device, and a travel speed sensor configured to generate a signal indicative of a travel speed of the machine. The steering mechanism may also have an operator input device having a deadzone. The deadzone may vary in response to the signal. The steering system may also have a controller in communication with the steering actuator, the operator input device, and the travel speed sensor. The controller may be configured to affect operation of the steering actuator in response to operation of the operator input device only when the operation of the operator input device deviates from the deadzone.
