  • Selecting non-human primates for research on aerosolized pathogens

    Inhaled pathogens are a serious bioterrorism threat, and developing therapeutics requires that preclinical researchers further explore how such pathogens manifest in animal models. This Physioblog post highlights a study focused on selecting the most appropriate non-human primate models for evaluating Rift Valley Fever Virus, a potential aerosolized bioterrorism agent.
  • Tips and Tricks from Scientific Services

    Simplify ECG Analysis. Electrocardiogram (ECG) waveform analysis can be time-consuming and complex. Accurate and consistent placement of fiducial marks, including the P, Q, S and T waves, is required for reliable ECG waveform analysis. DSI’s Ponemah software and Data Services team provide several options that can help simplify ECG waveform analysis, while helping researchers extract more ­­­meaningful information and save time. 

    • Data Insights is Ponemah’s latest tool for optimizing ECG analysis. With Data Insights, execute customized searches to locate arrhythmias, data patterns, and anomalies. Data Insights helps researchers reduce time analyzing ECG waveforms while delivering greater analysis capability.
    • DSI’s Data Services team is available to analyze, summarize and report on your experimental data. Reducing time spent on data analysis and reporting processes allows you more time to evaluate the experimental results.

  • Ask DSI Tech Support

    Q: “I’m setting up a new telemetry system for measuring continuous glucose with the HD-XG, should I use continuous sampling or scheduled sampling to collect data?”

    There are several nuances to glucose telemetry that are different from the way telemetry is used in cardiovascular or neurological studies. Scheduled sampling provides significant advantages in prolonged experiments where battery life, transmitter re-use and data management are issues of concern. In the case of the HD-XG glucose implant the battery life is intended to outlast the viability of the glucose sensor. Also the implant is not intended for re-use, and since the HD-XG device has a lower sample rate, the file size for continuous sampling is of little concern. 

    Although one might think the scheduled sampling option would be ideal for a slowly changing parameter like blood glucose, scheduled sampling is actually detrimental to the accuracy of the transmitter calibration process. The in vivo calibration for the HD-XG implant involves taking live blood samples during a glucose tolerance test and comparing the glucose values measured with a glucometer to the output of the telemetry implant in real time. If the software schedule is between sampling periods when blood is drawn, the resolution of the calibration can be dramatically reduced. To maximize the accuracy of the HD-XG telemetry transmitter our recommendation is to turn the implant on prior to implantation, collect data using continuous sampling, and leave the transmitter on for entire duration of the experiment.

  • Early Praise for Data Insights

    "Data Insights has provided a major advancement for the ability to identify and quantify arrhythmias in large animal telemetry studies. Using this technology I was able to efficiently analyze 24-hour telemetry datasets in a 40 animal study in a time- and cost-effective manner."

  • Product Transitions

    DSI is committed to providing the life science industry with reliable and innovative products with unsurpassed service. Long-term product availability is dependent upon many conditions, some of which are out of DSI’s control. It is our commitment that when the discontinuation of a product occurs, that it is done with the absolute minimum disruption and impact to our customers.

    Upon discontinuation a product can longer be ordered from DSI. DSI will notify customers and where possible, manage a last time purchase of the product. We will also recommend functional product equivalents as appropriate.

    The following products are currently being transitioned to new technologies:

    Implant Model

    Replacement Model

    Discontinuation Date


    PhysioTel™ HD-S10

    December 31, 2016


    PhysioTel Digital L11 or M11

    PhysioTel Digital M00

    December 31, 2106

    *The D70-CCTP does not have a direct replacement as PhysioTel Digital does not have an implant with two biopotential channels.

    Note: PhysioTel Digital is only available for sale in North America and Europe; as such the discontinuation dates listed above do not apply to countries outside of these regions.

    DSI is transitioning to new products to take advantage of technology improvements as well as due to regulatory requirements.

    DSI’s newest telemetry platforms, PhysioTel™ HD and PhysioTel Digital, leverage the latest technological advancements to offer scientists the ability to:

    • collect more physiological signals per study
    • see improved pressure sensing and reduced drift
    • experience greater biopotential channel filtering
    • integrate social housing capabilities

    In an effort to improve the health of our environment, the European Union introduced the Restriction of the Use of Certain Hazardous Substances (RoHS) Directive in 2002. The objective behind RoHS is to eliminate harmful substances which are commonly found in electronic equipment.

    DSI is contributing to a healthier environment by using the cleanest processes and reducing the use of hazardous materials. This initiative also benefits DSI customers as they will have access to the latest, environmentally-friendly physiologic monitoring products available through DSI.
