Selected current activity

  1. Seeking for new fields of application for the VoiceDiab system in type II diabetes, gestational diabetes and in persons with improper body weight.
  2. Studying relation between glycated hemoglobin A1c (HbA1c) concentration in blood and patient’s course of glycemia. Validation of mathematical models of HbA1c formation to predict changes of HbA1c concentration in response to varying glycemia courses. The experimental procedure uses an original combination of in vivo continuous glucose concentration monitoring, long-term in vitro culturing of the human erythrocytes and mathematical modeling of HbA1c formation in vivo and in vitro with HbA1c values scaled according to the most specific analytical methods.
  3. Development of new more accurate and precise methods of wound surface area measurement. As a result, the application AreaMe for Windows Mobile 6.5 system and a Planimator app for Android 4.0 were developed and tested. (https://www.researchgate.net/project/Planimator-App-for-wound-area-measurement-for-Android). The Planimator app may be send to any user for the research purposes (contact e-mail: pfoltynski(at)ibib.waw.pl).
  4. Development of a bioreactor (capillary module), which can simulate human blood vessel, with capillary polysulfone membranes covered with the human umbilical vein endothelial cells (HUVECs). Such artificial blood vessel may be used in experimental models in studies pathophysiological mechanisms of different diseases.

  1. Studying influence of zinc oxide nanoparticles on endothelial cells cultured in hollow fiber bioreactor under dynamic flow of growth medium.
  2. Metabolic profile analysis of biofluids and tissue extracts from humans and animals using NMR spectroscopy for analysis of hydrophilic and hydrophobic components. As metabolomics is a fingerprint for early disease diagnostic, detected biomarkers could indicate some disease pathomechanisms.
