    Abstract: Exemplary embodiments include systems, methods, and compositions for the intra-operative detection of target tissue. At least one embodiment includes a fluorescence detection instrument that may be used for intra-operative detection of a fluorescent targeting agent, its binding site, and its interaction within cancer tissues. An exemplary embodiment is highly sensitive to the local deposition of fluorescence agents even at a low concentration. In at least one embodiment, the system includes a handheld navigation instrument that is usable to excite, detect, and report the fluorescent deposition of the targeting agent in real-time. In alternative embodiments, the system includes a wearable unit to excite, detect, and visually report the fluorescent deposition of the targeting agent to the user. The wearable unit includes eyewear that allow the user to perform image-guided surgery based on the near real-time fluorescence detection of the fluorescent targeting agent.

    Abstract: An oral solid dosage formulation is provided which contains a Factor Xa inhibitor for which oral bioavailability is not reduced by co-administration of antacids, H2 antagonists and proton pump inhibitors. Such solid dosage formulation includes the Factor Xa inhibitor of the structure, a pharmaceutically acceptable carrier, and an acid component, such as tartaric acid, whereby upon ingestion of the oral solid dosage formulation, the acid component increases solubility of the Factor Xa inhibitor in the local environment of the dissolving solid dosage formulation resulting in an otherwise lower degree of supersaturation of the Factor Xa inhibitor in such environment, than if the acid were not present. The result is that precipitation of the Factor Xa inhibitor in the form of its insoluble free base is minimized during dissolution of the Factor Xa inhibitor thereby increasing its oral bioavailability. A method for enhancing bioavailability of the Factor Xa inhibitor is also provided wherein an acid such as tartaric acid is incorporated with the solid dosage pharmaceutical carrier for the Factor Xa inhibitor.

    Abstract: Differences of electromagnetic (EM) properties between healthy and cancerous tissues allow detection of abnormal conditions occurring in a tissue of an animal, for example, intra-operative cancer detection. By using a time-varying EM field, electrical eddy currents are generated in the tissue sample, and assessed using phase-sensitive detection. In some aspects, a change in phase shift between the voltage in a receiver coil and the voltage in a driver coil provide a direct and immediate indication of differences in EM properties of specimens.
