Background

iox stands for isolated organ experiments, because it was originally designed as software for recording from isolated tissue. In response to demand from the preclinical research community, the software was developed for other applications including cardiovascular and pulmonary research, such as plethysmography, telemetry
Telemetry
Telemetry is a technology that allows measurements to be made at a distance, usually via radio wave transmission and reception of the information. The word is derived from Greek roots: tele = remote, and metron = measure...

 and behavioural studies.

Some functionalities have given rise to fully featured spin-off software applications. The ecg analysis, data reduction and data management components of iox gave rise to ecgAUTO, datanalyst and studyDESIGNER. These applications together make up the emka TECHNOLOGIES software suite.

Overview

IOX acquires data on PCs. It also performs signal processing

 and real-time analysis.

Up to 64 inputs can be recorded simultaneously with independent sampling rates of 10 Hz to 100 kHz. iox acquires analog signals from any device. The standard acquisition card is the National Instruments card with a 12-bit converter and with a range of ±5 V (giving a resolution of 2.5 mV).

Inputs may be physical (signal is a physical measurement) or calculated (signal is based on physical signals).

iox's architecture allows researchers to adapt the software to particular needs. For example, researchers performing plethysmography studies in freely moving animals will use the RF analyzer that uses a single flow input.

Add-on modules, or analyzers, are specially designed to analyze a specific type of signal. Each analyzer is developed using algorithms widely accepted and validated by the life science research community.

Modules are available to comply with GLP

Furthermore, a direct link interface may be developed between iox and third-party LIMS - as was done with Instem's ProvantisTM software.

Center for Integrated Functional Exploration, France.

The Centre is one of the technology platforms of the Institut Claude Bernard, run by a hospital-university consortium. Its particular expertise is functional exploration of small rodents and functional imaging techniques, for in vivo characterization of cardiovascular and metabolic phenotypes. Specific applications include ecg analysis and PV loops analysis, which make use of iox for acquisition and real-time analysis, ecgAUTO for post-acquisition analysis and Millar pressure-volume recording hardware.

Outcomes
Developing iox software has also lead to many benefits and outcomes for scientists and science.

emka TECHNOLOGIES, in common with preclinical researchers worldwide, is committed to the humane use of animals in science, as espoused by the 3R's guiding principles, which aim to replace, reduce and refine the use of animals in scientific research. Several features of the iox data acquisition system can help researchers to achieve the 3R's.
The modular and continually evolving nature of iox make it suitable for use with any in vitro models that can be used in place of whole animal in vivo models (e.g. study of isolated heart, vascular or other smooth muscle tissue).
Moreover, iox is also capable of acquiring many different types of signals: for example, it is possible to record cardiovascular data at the same time as respiratory data (plethysmography with transmitter implants). By maximizing the amount of data recorded from any given experiment, iox potentially reduces the number of animals required. In addition, the real-time display of calculated parameters allows you to take appropriate measures immediately so that the risk of wasted experiments due to human error or faulty setup is much reduced.
