Results of nanomaterials testing for skin wounds nursing
Juhás, Štefan ; Juhásová, Jana
Using minipigs experiments, we tested the healing of fresh wounds treated with different nanofibrous materials and compared them with standard treatment. From predefined wounds, samples were taken at regular intervals for histological analysis, microbiology, wound measurements and photodocumentation. Blood was also collected from the miniprasate to determine pro-inflammatory cytokines.
Results of in vivo nanomaterials testing using minipig
Juhás, Štefan ; Juhásová, Jana
Using in vivo experiments we tested healing of a fresh wound treated with a nanofibrous cover. From predefined wounds, samples were taken at regular intervals for histological analysis, wound measurements and photodocumentation were performed.

Recent promising treatments for Huntington’s disease (HD) may require pre-clinical testing in large animals. In 2009, we generated HD transgenic (TgHD) minipigs with one copy encoding the N-terminal part (548 aa) of human huntingtin (HTT) with 124 CAG/CAA repeats integrated into chromosome 1 q24-q25. The successful germ line transmission occurred through four successive generations.
Potent anti-spasticity and anti-nociceptive effect of subpial GAD65 and VGAT gene delivery in rat and mice
Maršala, M. ; Tadokoro, T. ; Hernandez, M. B. ; Navarro, M. ; Maršala, S. ; Miyanohara, A. ; Juhás, Štefan ; Juhásová, Jana ; Platoshyn, O.
In previous studies we have developed a novel spinal subpial (SP) AAV delivery technique in adult mice, rats and minipigs. Using this technique we have demonstrated potent and wide-spread transgene (GFP) expression in spinal white and gray matter after a single SP bolus of AAV9-UBI-GFP.
Cell therapy in animal models - preclinical studies
Juhásová, Jana ; Motlík, Jan (advisor) ; Grim, Miloš (referee) ; Jendelová, Pavla (referee)
The progress of cell therapy can be greatly facilitated by using suitable experimental models. It is essential to verify the clinical usefulness of new healing procedures obtained in studies on laboratory animals by using a large animal model. One of suitable models well acceptable in medical community is undoubtedly the miniature pig, which resembles humans in terms of physiology and body proportions. This PhD thesis presents the summary of our experimental studies relating to possible exploitation of mesenchymal and neural stem cells in the healing of locomotive apparatus and neural tissue disorders in humans or animals. The first part of the thesis briefly describes the current issue of cell therapy and animal models, mesenchymal cells and/or their combination with new types of scaffolds, neurogenesis, neural stem cells and their potential application in therapy of spinal cord injury. The second part is focused on the goals and methodology, the individual publications being listed in the third part. Our experiments with iatrogenic physeal defect in rabbits, which served as a model of the occurrence of valgous deformation in the clinical practice, showed the positive preventive and therapeutical effects of a new type of scaffolds seeded with allogeneic mesenchymal stem cells in animals without...
Evaluation of efficacy and bio-distribution of AAV5-miHTT in HD minipig brain
Bohuslavová, Božena ; Juhás, Štefan ; Juhásová, Jana ; Ellederová, Zdeňka ; Motlík, Jan
Healthy minipigs (n=29) were pre-screened for serum AAV5 neutralizing antibodies (NABs) in serum by uniQure. Conclusions: Intrastriatal/intrathalamic bilateral application of AAV5-CAG-miHtt(3e13/1e13gctotal) or PBS/Sucrose (54μl/216μl) similarly to AA5-CAG-GFP didn´t cause any neurological deficit in transgenic as well as wild type animals. The body weight increased in all animals 84 days after AAV5-CAG-miHtt/PBS-Sucroseintrastriatal/intrathalamic delivery with two exceptions TGanimal L616 (AAV5-CAG-miHtt1e 13g ctotal) and WTanimal L485 (AAV5-CAG-miHtt3e13gc total). The TG boar N176 from group VII (PBS/Sucrose) died during narcosis 56 days after IP/IT application), shortly after CSF and blood collection.The boar breathed heavily and intermittently, then the heart stopped beat and resuscitation failed. We immediately flushed them by 20 L of PBS with heparin and collect all tissues. All animals had normal food consumption. Inflammatory proces in AAV5-CAG-miHtt (1e13 gc total) seems to be similar to PBS/Sucrose injected animals accompanied with no detectable histological pathologies.
