Oroboros Workshops in O2k-Network Labs
Concept
Oroboros Events are organized in cooperation with O2k-Network Labs as a service for the O2k-Network Lab, and feedback support for Oroboros Instruments to disseminate the newest developments in the region by invitation to external participants.
O2k-Workshop program
- General: Focus on four sessions:
- Setting up the O2k and instrumental service.
- Protocols for high-resolution respirometry: focus on combined measurement of respiration and another parameter (e.g. hydrogen peroxide production, mt-membrane potential).
- O2k-Demo experiment: Combined measurement of respiration (and hydrogen peroxide production).
- Extending real-time data analysis to evaluation of results, discussion of protocol design, Oroboros in science.
- A detailed program including the timing of sessions is developed in collaboration with the local host institution.

O2k-Workshops and expeditions: environments at high altitude and cold
Oxygen delivery to the tissue is a critically limiting factor frequently studied in high altitude environments and uner hypothermia. Very few investigations, however, address the equally important metabolic process of cellular oxygen utilization under short-term and long-term hypobaric hypoxia. Oroboros Instruments is a highly competent potential partner of a multi-disciplinary and international research group focused on clinical and biological aspects of Human life at high altitude. We have participated in several expeditions to high altitude to study short-term acclimatization and adaptation of Human populations to high altitude and low temperature (Monte Rosa, Italy; Mt. Chacaltaya, Bolivia; Everest Base Camp, Nepal; Alaska, USA; Spitsbergen, Norway). We are specialists in instrumental development and applications in mitochondrial physiology and have taken high-resolution respirometry to the extremes of field work at high altitude, with long-term experience in the organization of workshops all-over the world. In methodological and technical workshops, participants are introduced to the conceptual and practical basis of the diagnosis of mitochondrial function and dysfunction. Specifically, the boundary conditions prevailing in laboratories available at high altitude can be taking into account, which require the highest performance standards for electronic instruments and their application. In addition we offer pre-expedition training to international partners in our research laboratory, for scientists and students to gain competence for the challenges met when working in high altitude environments. As a long-term perspective, we aim at elaborating standards for the evaluation of cell respiration and mitochondrial function to diagnose diseases and find potential targets to improve the state of health and quality of Human life in high altitude and hypothermic environments. These standards can be implemented not only in the participating countries but may become a template for world-wide dissemination.
