Research Objective

The Unit 20 years now has successfully taken part in several European and national eHealth and knowledge management projects. Within the realm of these projects eHealth and eLearning platforms have been developed and hosted within NCSR premises.

The core business and skills of the unit includes:

  • Medical informatics
  • Web services and technologies and mobile applications to support healthcare e.g. Tele-health platforms to enhance the provision of medical services and emergency services for both citizens and travelers in remote/isolated regions, for chronic patients and disable and ageing population.
  • Unobtrusive monitoring services and applications for home care services like Internet of Things platforms and ontologies for supporting assistive living,  
  • Decision Support Services to Professionals using information extraction from heterogeneous content for enhancement of diagnosis with Electronic Health Records and intelligent algorithms
  • Information systems and knowledge management,
  • Foresight and strategic planning and
  • Competency-based learning.

Future Objectives

Our aim is to connect society, business-innovation and research by continuously develop, validate and bring out of the lab and into the market state of the art services for making life better.

  1. We intend to enhance new research perspectives stressing interdisciplinary approaches in areas with strong societal and economic importance like health, assistive living and wellness. The areas of research are:
  2. use of Intelligence to support models of digital doctors, automatic diagnosis, and multispectral imaging
  3. develop virtual assistants to support self-management services
  4. further develop models for age friendly homes
  5. work on integrated care models
  6. Support the digital transformation of society and organizations (education, organizational activities, processes, competencies and models) to fully leverage the potential of digital technologies
  7. Transform research results into tangible innovative applications and services and commercialize the research findings coming from NCSR relevant projects.

Research Activities

  • ICT in Healthcare and Assistive Living, Knowledge Management
  • Competency based Learning, Foresight & Strategic planning to support AI in Electronic Health Record domain, search technologies and NLP

Laboratory Description

The Human Tissue Bank of NCSR “DEMOKRITOS” is one of the first legislated laboratories of the Center, always mentioned in the laws of the Ministry of Health regarding transplantations. The main objective of Human Tissue Bank (HTB) is the collection of various human tissues, their processing and the production of grafts to be used in Regenerative Medicine and Reconstructive Surgery.

It is recently licensed as a Tissue and Cell Bank by the Ministry of Health (Greek Government Gazette 768, 26.02.2021) /Scientific Responsible: Helen Vavouraki .Member of the European Association of Tissue Banks, it is the only bank of its kind in Greece, applying its “knowhow” in the processing of a great variety of human tissues. It has gradually developed the necessary expertise in each procedure (procurement, tissue processing, irradiation sterilization and disposal of tissue grafts) involved in the Tissue Banking. All the above activities comply with the European Directives 23/2004, 17/2006 and 86/2006 concerning human tissues and cells, as they were implemented in Greece by the 26/2008 Law, as well as, to the recommendations of International Atomic Energy Agency (IAEA).

In over 46 years of continuous operation, HTB has delivered more than 54.000 tissue grafts without any reported quality-related problems. All procedures taking place in the Bank are fully computerized and accredited according to ISO 9001/2015. It is a great concern for us to constantly be updated in quality control topics and to ensure our compliance with the Greek and European Standards.

The produced grafts are delivered to various hospitals, health clinics, medical and dental laboratories, all over the country. The Tissue Bank’s research interests are mainly focused on the study of the activity of the produced grafts, the optimization of the production methods, the process of new types of tissues, the development of new techniques and new graft products. Its research activities are therefore based on collaborations with universities and healthcare institutions, in order to promote Public Health by launching improved products, publishing original papers and participating in doctorate degrees (Ph.D. theses).
