    Notes: Abstract A sodium-dependent phosphate transporter (type II Na/Pi-cotransporter) was isolated which is expressed in apical membranes of proximal tubules and exhibits transport characteristics similar as described for renal reabsorption of phosphate. Type II associated Na/Pi-cotransport is electrogenic and results obtained by electrophysiological measurements support a transport model having a stoichiometry of 3 Na+/HPO4 =. Changes of transport such as by parathyroid hormone and altered dietary intake of phosphate correlate with changes of the number of type II cotransporters in the apical membrane. These data suggest that the type II Na/Pi-cotransporter represents the main target for physiological and pathophysiological regulation.

    Preliminary development of a radiotelemetry system for biological applications (1986)
    Springer
    Medical & biological engineering & computing 24 (1986), S. 281-291 
    Details
    ISSN: 1741-0444
    Keywords: Biotelemetry ; Crystal control ; Multichannel ; Transcutaneous power
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract The design and prototype realisation of a complete radiotelemetry system for long-term monitoring of laboratory animals is described. The transmitter component is potentially implantable and transcutaneously powered using a single-component 200 kHz magnetic field. Monitoring of up to four data channels is possible using time-division multiplexing. The FM carrier is quartz crystal controlled to ensure long-term system stability and satisfy UK biomedical telemetry regulations. Implementation of the system would now require miniaturisation of the implantable transmitter component.
