Disciplines in Life Sciences implicate a high degree of practical laboratory expertise. The University of Applied Sciences (UAS) in Vienna, Austria, has thus been endeavoured offering students a high qualitative education integrating hybrid courses based on PBL principles, which consist of on-site (including the transmission of necessary background and practical laboratory training) and off-site (including self-study phases) sessions. As practical laboratory units are central in those courses, the restrictive measures, including the transition to a complete online teaching format due to the first Covid-19-pandemic lock-down, had severe effects on the implementation and the quality of the curriculum. According to surveys made specifically to address this problematic situation, it can be concluded that on-site practical units are fundamental for certain disciplines such as Life Sciences.}, subject = {Problem-based Learning}, language = {en} } @article{QuartinelloTallianAueretal., author = {Quartinello, Felice and Tallian, Claudia and Auer, Julia and Sch{\"o}n, Herta and Vielnascher, Robert and Weinberger, Simone and Wieland, Karin and Weihs, Anna and Rollett, Alexandra and Lendl, Bernhard and Teuschl, Andreas and Pellis, Alessandro and G{\"u}bitz, Georg}, title = {Smart Textiles in Wound Care: Functionalization of Cotton/PET Blends with Antimicrobial Nanocapsules}, series = {Journal of Materials Chemistry B}, journal = {Journal of Materials Chemistry B}, subject = {Smart textiles}, language = {en} } @article{TallianHerreroRollettStadleretal., author = {Tallian, Claudia and Herrero-Rollett, Alexandra and Stadler, Karina and Vielnascher, Robert and Wieland, Karin and Weihs, Anna and Pellis, Alessandro and Teuschl, Andreas and Lendl, Bernhard and Amenitsch, Heinz and Guebitz, Georg M.}, title = {Structural insights into pH-responsive drug release of self-assembling human serum albumin-silk fibroin nanocapsules.}, series = {European Journal of Pharmaceutics and Biopharmaceutics}, journal = {European Journal of Pharmaceutics and Biopharmaceutics}, abstract = {Inflammation processes are associated with significant decreases in tissue or lysosomal pH from 7.4 to 4, a fact that argues for the application of pH-responsive drug delivery systems. However, for their design and optimization a full understanding of the release mechanism is crucial. In this study we investigated the pH-depending drug release mechanism and the influence of silk fibroin (SF) concentration and SF degradation degree of human serum albumin (HSA)-SF nanocapsules. Sonochemically produced nanocapsules were investigated regarding particle size, colloidal stability, protein encapsulation, thermal stability and drug loading properties. Particles of the monodisperse phase showed average hydrodynamic radii between 438 and 888 nm as measured by DLS and AFM and a zeta potential of -11.12 ± 3.27 mV. Together with DSC results this indicated the successful production of stable nanocapsules. ATR-FTIR analysis demonstrated that SF had a positive effect on particle formation and stability due to induced beta-sheet formation and enhanced crosslinking. The pH-responsive release was found to depend on the SF concentration. In in-vitro release studies, HSA-SF nanocapsules composed of 50\% SF showed an increased pH-responsive release for all tested model substances (Rhodamine B, Crystal Violet and Evans Blue) and methotrexate at the lowered pH of 4.5 to pH 5.4, while HSA capsules without SF did not show any pH-responsive drug release. Mechanistic studies using confocal laser scanning microscopy (CLSM) and small angle X-ray scattering (SAXS) analyses showed that increases in particle porosity and decreases in particle densities are directly linked to pH-responsive release properties. Therefore, the pH-responsive release mechanism was identified as diffusion controlled in a novel and unique approach by linking scattering results with in vitro studies. Finally, cytotoxicity studies using the human monocytic THP-1 cell line indicated non-toxic behavior of the drug loaded nanocapsules when applied in a concentration of 62.5 µg mL-1.}, subject = {Biomaterial}, language = {en} } @misc{TeuschlSchuhWeihsetal., author = {Teuschl, Andreas and Schuh, Christina and Weihs, Anna and Guillaume, Olivier and Monforte Vila, Xavier and Redl, Heinz and Kaplan, David and R{\"u}nzler, Dominik}, title = {Tailoring bioactivity of silk-based biomaterials via delivering and functionalization strategies with fibrinogen/thrombin, plant lectins or laminin}, subject = {Biomaterials}, language = {en} } @misc{SalzerRiederMonforteVilaetal., author = {Salzer, Elias and Rieder, Bernhard and Monforte Vila, Xavier and Weihs, Anna and R{\"u}nzler, Dominik and Teuschl, Andreas}, title = {Evaluation of a novel hydrostatic pressure bioreactor on bovine cartilage chips}, subject = {Bioreactor}, language = {en} } @misc{SlezakRoseHercheretal., author = {Slezak, Paul and Rose, Roland and Hercher, David and Weihs, Anna and Fuchs, Christiane and Redl, Heinz and Mittermayr, Rainer and Slezak, Cyrill}, title = {Tracking therapeutic shockwaves and their impact on regeneration}, subject = {Shockwave Therapy}, language = {en} } @inproceedings{FuchsWeihsSzwarcetal., author = {Fuchs, Christiane and Weihs, Anna and Szwarc, Dorota and Mittermayr, Rainer and R{\"u}nzler, Dominik and Teuschl, Andreas}, title = {Shock wave treatment of muscle (stem) cells - a new implementation for regeneration}, series = {Proceedings of the 20th International Congress of the ISMST}, booktitle = {Proceedings of the 20th International Congress of the ISMST}, subject = {Shockwave treatment}, language = {en} } @misc{FuchsWeihsSzwarcetal., author = {Fuchs, Christiane and Weihs, Anna and Szwarc, Dorota and Mittermayr, Rainer and R{\"u}nzler, Dominik and Teuschl, Andreas}, title = {Shock wave treatment of muscle (stem) cells - a new implementation for regeneration}, subject = {Shockwave treatment}, language = {en} } @misc{TeuschlWeihsFuchsetal., author = {Teuschl, Andreas and Weihs, Anna and Fuchs, Christiane and Monforte Vila, Xavier}, title = {Silk as a versatile biomaterial for musculoskeletal tissue engineering}, subject = {Silk}, language = {en} }
