    摘要: Methods and systems for inducing and passively detecting stable cavitation and/or inertial cavitation for targeted drug delivery across a biological membrane are disclosed. Such methods include administering vesicles having a nucleating agent and a therapeutic drug to a vascular system of a patient, and providing an active interval of ultrasonic exposure substantially throughout a targeted treatment zone. The ultrasonic exposure is produced by a source transducer at a specified fundamental frequency, amplitude, duty cycle, and duration. The methods also include detecting a scattered ultrasonic wave, where the scattered ultrasonic wave is received by a detection transducer. Detection of the scattered ultrasonic wave is indicative of stable and/or inertial cavitation. The ultrasonic exposure is provided intermittently in the active intervals separated by rest periods, and substantially less ultrasonic exposure is provided during the rest period than during the active interval.

    摘要: The present invention provides a new class of non-viral transduction vectors that can be used for both in vivo and in vitro applications. The present invention also provides a gene transfer vector that has comparable efficiency to a viral vector without the potential for a life-threatening immune response. Complexes according to the invention or portions thereof, can comprise a cellular delivery molecule or agent that can facilitate the translocation of the complex or portion thereof into cells. In some embodiments, cellular delivery molecules for use in the present invention may comprise one or more polymers of the present invention, e.g., polyamides, dendritic macromolecules and carbohydrate-containing degradable polyesters.

    摘要: Functional biological synthetic composite (BSC) membranes comprising phospholipids, biological membrane proteins and porous supports or membranes are provided. Lipid bilayers are formed on porous polycarbonate (PC), polyethylene terephthalate (PETE) and poly (I-lactic acid) (PLLA) membranes and in laser-drilled pores in a multi-well plastic plate as measured by increased resistance or decreased currents. BSC's comprising functional reconstituted Kv1.5 K channel and/or H/K ATPase transport proteins are also provided c inhibitor), methods of manufacture, and high throughput screening assays employing the inventive membranes are also provided.
