    摘要: A capsule is disclosed which includes a flexible outer shell capable of transforming into an asymmetric shape; an internal medium encapsulated by the outer shell, the medium including a plurality of magnetic particles, wherein the magnetic particles can move in response to an applied magnetic field. A valve system includes an in-line valve sized to fit within a flow channel including a capsule having a flexible outer shell containing an internal medium encapsulated by the outer shell, the medium including a plurality of magnetic particles; and a magnetic field source disposed about the exterior wall of the channel.

    摘要: The present invention relates to an in vivo method of monitoring an analyte in a subject. This method involves providing an expression vector that encodes a biosensor molecule, the biosensor molecule comprising an analyte binding domain and a signal domain. The biosensor molecule produces a signal from the signal domain upon binding of the analyte by the analyte binding domain. The signal is detectable by a non-invasive means. The expression vector is introduced locally into in vivo cells of a subject under conditions effective to express the biosensor molecule in the cells. The signal from the expressed biosensor molecule is detected by a non-invasive means, thereby monitoring the analyte in the subject in vivo.

    摘要: An integrated bioinstrumentation system, combining an accurate and robust quasi 1D computational model with experimental peripheral measurements, is designed to extract information on other quantities of interest, for which the direct measurements are not feasible. The system is able to quantify and visualize the distributions of a cardiac output (CO), aortic blood pressure (BP), flow, velocity, and aortic arterial compliance, based on a peripheral analysis of a pulse transit time (PTT) measured at the available peripheral sites. A preliminary calibration stage extracts the arterial properties from simultaneous measurements of a pulse transit time, and an upper arm blood pressure. Obtained transfer functions, linking noninvasive peripheral measurements to the aortic pressure, cardiac output, aortic compliance and others serve to quantify the indicators of cardiac morbidity and mortality.
