Besides the evident need to create functional skeletal muscle tissue for the repair of volumetric muscle defects, there is also growing demand for platforms to study muscle-related diseases, such as muscular dystrophies or sarcopenia. Currently, numerous studies exist that have employed a variety of biomaterials, cell types and strategies for maturation of skeletal muscle tissue in 2D and 3D environments. However, researchers are just at the beginning of understanding the impact of different culture settings and their biochemical (growth factors and chemical changes) and biophysical cues (mechanical properties) on myogenesis. With this review we intend to emphasize the need for new in vitro skeletal muscle (disease) models to better recapitulate important structural and functional aspects of muscle development. We highlight the importance of choosing appropriate system components, e.g., cell and biomaterial type, structural and mechanical matrix properties or culture format, and how understanding their interplay will enable researchers to create optimized platforms to investigate myogenesis in healthy and diseased tissue. Thus, we aim to deliver guidelines for experimental designs to allow estimation of the potential influence of the selected skeletal muscle tissue engineering setup on the myogenic outcome prior to their implementation. Moreover, we offer a workflow to facilitate identifying and selecting different analytical tools to demonstrate the successful creation of functional skeletal muscle tissue. Ultimately, a refinement of existing strategies will lead to further progression in understanding important aspects of muscle diseases, muscle aging and muscle regeneration to improve quality of life of patients and enable the establishment of new treatment options.}, subject = {Bioreactor}, language = {en} } @article{TomaschMaleinerHeheretal., author = {Tomasch, Janine and Maleiner, Babette and Heher, Philipp and Rufin, Manuel and Andriotis, Orestis G. and Thurner, Philipp J. and Redl, Heinz and Fuchs, Christiane and Teuschl-Woller, Andreas H.}, title = {Changes in Elastic Moduli of Fibrin Hydrogels Within the Myogenic Range Alter Behavior of Murine C2C12 and Human C25 Myoblasts Differently}, series = {Froniers in Bioengineering and Biotechnology}, volume = {10}, journal = {Froniers in Bioengineering and Biotechnology}, pages = {836520}, abstract = {Fibrin hydrogels have proven highly suitable scaffold materials for skeletal muscle tissue engineering in the past. Certain parameters of those types of scaffolds, however, greatly affect cellular mechanobiology and therefore the myogenic outcome. The aim of this study was to identify the influence of apparent elastic properties of fibrin scaffolds in 2D and 3D on myoblasts and evaluate if those effects differ between murine and human cells. Therefore, myoblasts were cultured on fibrin-coated multiwell plates ("2D") or embedded in fibrin hydrogels ("3D") with different elastic moduli. Firstly, we established an almost linear correlation between hydrogels' fibrinogen concentrations and apparent elastic moduli in the range of 7.5 mg/ml to 30 mg/ml fibrinogen (corresponds to a range of 7.7-30.9 kPa). The effects of fibrin hydrogel elastic modulus on myoblast proliferation changed depending on culture type (2D vs 3D) with an inhibitory effect at higher fibrinogen concentrations in 3D gels and vice versa in 2D. The opposite effect was evident in differentiating myoblasts as shown by gene expression analysis of myogenesis marker genes and altered myotube morphology. Furthermore, culture in a 3D environment slowed down proliferation compared to 2D, with a significantly more pronounced effect on human myoblasts. Differentiation potential was also substantially impaired upon incorporation into 3D gels in human, but not in murine, myoblasts. With this study, we gained further insight in the influence of apparent elastic modulus and culture type on cellular behavior and myogenic outcome of skeletal muscle tissue engineering approaches.

The aim of this study is to obtain and design porous 2D fibroin-based cell matrices by femtosecond laser-induced microstructuring for future applications in muscle tissue engineering. Ultra-fast laser treatment is a non-contact method, which generates controlled porosity-the creation of micro/nanostructures on the surface of the biopolymer that can strongly affect cell behavior, while the control over its surface characteristics has the potential of directing the growth of future muscle tissue in the desired direction. The laser structured 2D thin film matrices from silk were characterized by means of SEM, EDX, AFM, FTIR, Micro-Raman, XRD, and 3D-roughness analyses. A WCA evaluation and initial experiments with murine C2C12 myoblasts cells were also performed. The results show that by varying the laser parameters, a different structuring degree can be achieved through the initial lifting and ejection of the material around the area of laser interaction to generate porous channels with varying widths and depths. The proper optimization of the applied laser parameters can significantly improve the bioactive properties of the investigated 2D model of a muscle cell matrix.

With the wide usage of viral based vector systems in combination with mammalian cell lines for the production of biopharmaceuticals, the presence of replication competent viral particles needs to be avoided and potential hazards carefully assessed. Consequently, regulatory agencies recommend viral clearance studies using plaque assays or TCID50 assays to evaluate the efficiency of the production process in removing viruses. While plaque assays provide reliable information on the presence of viral contaminations, they are still tedious to perform and can take up to two weeks to finish. To overcome some of these limitations, we have automated, miniaturized and integrated the dual cell culture bioassay into a common lab-on-a-chip platform containing embedded electrical sensor arrays to enrich and detect infectious viruses. Results of our microfluidic single step assay show that a significant reduction in assay time down to 3 to 4 days can be achieved using simultaneous cell-based viral amplification, release and detection of cytopathic effects in a target cell line.

Emerging advances in high throughput sequencing techniques, in particular DNA methylation data analysis, have resulted in the establishment of precise human and murine age prediction tools. In vertebrates, methylation of cytosine at the C5 position of CpG dinucleotides is executed by DNA methyltransferases (DNMTs) whereas the process of enzymatic demethylation is highly dependent on the activity of the ten-eleven translocation methylcytosine dioxygenase (TET) family of enzymes. Here, we report the identification of the key players constituting the DNA methylation machinery in the short-lived teleost aging model Nothobranchius furzeri. We present a comprehensive spatio-temporal expression profile of the methylation-associated enzymes from embryogenesis into late adulthood, thereby covering the complete killifish life cycle. Data mining of the N. furzeri genome produced five dnmt gene family orthologues corresponding to the mammalian DNMTs (DNMT1, 2, 3A, and 3B). Comparable to other teleost species, N. furzeri harbors multiple genomic copies of the de novo DNA methylation subfamily. A related search for the DNMT1 recruitment factor UHRF1 and TET family members resulted in the identification of N. furzeri uhrf1, tet1, tet2, and tet3. Phylogenetic analysis revealed high cross-species similarity on the amino acid level of all individual dnmts, tets, and uhrf1, emphasizing a high degree of functional conservation. During early killifish development all analyzed dnmts and tets showed a similar expression profile characterized by a strong increase in transcript levels after fertilization, peaking either at embryonic day 6 or at the black eye stage of embryonic development. In adult N. furzeri, DNA methylation regulating enzymes showed a ubiquitous tissue distribution. Specifically, we observed an age-dependent downregulation of dnmts, and to some extent uhrf1, which correlated with a significant decrease in global DNA methylation levels in the aging killifish liver and muscle. The age-dependent DNA methylation profile and spatio-temporal expression characteristics of its enzymatic machinery reported here may serve as an essential platform for the identification of an epigenetic aging clock in the new vertebrate model system N. furzeri.}, subject = {Tissue Engineering}, language = {en} } @inproceedings{WiessnerMachacekLinkLeitner, author = {Wießner, Katharina and Machacek-Link, Thomas and Leitner, Rita}, title = {Encouraging the development of higher-order cognitive skills via applied exercises and web-based self-assessment to teach the basic principles in molecular biology.}, series = {PIXEL NPSE2021, M{\"a}rz 2021}, booktitle = {PIXEL NPSE2021, M{\"a}rz 2021}, abstract = {The responsibility of a lecturer is not only to share his or her knowledge with the students in an easy to understand manner, but also to help the students to embed new knowledge and to encourage the development of higher-order cognitive skills via applied exercises. In order to meet the growing demand for blended learning approaches a new course concept was established in autumn 2018. To enhance comprehension and to provide opportunities for self-assessment, web-based training units were implemented by using the interactive learning software "Articulate Storyline". Students had to prepare at home for the course units by completing interactive chapters. Their learning outcome was assessed by online quizzes at the end of each chapter. Online Training chapters allowed time to focus on selected topics and to repeat key messages in following presence units. Additionally, guided group exercises were performed to promote analytic skills and abstract thinking. The students had to apply and combine their knowledge to solve problem-based challenges. An optional revision course was offered to the students, which allowed for interactive repetition of the acquired knowledge with the focus on student-to-lecturer dialog. An analysis based on a written evaluation of this course resulted in a positive feedback from the students, in particular regarding the guided exercises and the offered revision course. According to the students the group exercises allowed to process the learned subjects, promoted the group climate and were a convenient diversion from the frontal lecture format. Students who attended the revision course on a regular basis showed a better performance at the final exam and exceeded especially at interdisciplinary questions. The first implementation of this master´s degree course indicated that the combination of web-based training elements with frontal lecture elements, guided exercises stimulating cognitive skills and an optional revision course can teach students the basics of biology in an understandable way.

Therefore, strategies to reduce rhBMP-2 dosage are desirable. Silk scaffolds show great promise due to their favorable biocompatibility and their utility for various biofabrication methods. For this study, we generated silk scaffolds with axially aligned pores, which were subsequently treated with 10× simulated body fluid (SBF) to generate an apatitic calcium phosphate coating. Using a rat femoral critical sized defect model (CSD) we evaluated if the resulting scaffold allows the reduction of BMP-2 dosage to promote efficient bone repair by providing appropriate guidance cues. Highly porous, anisotropic silk scaffolds were produced, demonstrating good cytocompatibility in vitro and treatment with 10× SBF resulted in efficient surface coating. In vivo, the coated silk scaffolds loaded with a low dose of rhBMP-2 demonstrated significantly improved bone regeneration when compared to the unmineralized scaffold.

Many enzymatic or non-enzymatic based strategies to extract ECM proteins from tissues were published over the past years. However, every single isolation strategy reported so far is associated with specific bottlenecks. In this study, frequently used strategies to isolate ECM from human placenta or adipose tissue using Tris-, serum-, or pepsin-based buffers were compared. The resulting ECM proteins were biochemically characterized by analysis of cellular remnants using Hoechst DNA staining, glycosaminoglycan (GAG) content by dimethylmethylene blue, visualization of protein bands using sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis combined with amino acid quantification, and assessment of the proangiogenic profile using an angiogenesis array. Tris-NaCl-extracted ECM proteins showed a high heterogenic degree of extracted proteins, bioactive growth factors, and GAGs, but no collagen-I. Active serum-extracted ECM showed significant lower DNA remnants when compared with the Tris-NaCl isolation strategy. Pepsin-extracted ECM was rich in collagen-I and low amounts of remaining bioactive growth factors. This strategy was most effective to reduce DNA amounts when compared with the other isolation strategies. Pepsin-extracted ECM from both tissues easily gelled at 37°C, whereas the other extracted ECM strategies did not gel at 37°C (Tris-NaCl: liquid; serum: sponge). All relevant characteristics (DNA residues, ECM diversity and bioactivity, shape) of the extracted ECM proteins highly depend on its isolation strategy and could still be optimized.

These methods, either chemical or physical, change the structure of SF and improve its mechanical stability, although each method has its advantages and disadvantages. While chemical crosslinking agents guarantee the mechanical strength of SFH through the generation of covalent bonds, they could cause some toxicity, and their usage is not compatible with a cell-friendly technology.

Bone loss in the humeral head is associated with repair failure after rotator cuff reconstruction. Bisphosphonates (eg, zoledronic acid) increase bone mineral density. Hypothesis: Zoledronic acid improves bone mineral density of the humeral head and biomechanical properties of the enthesis after reconstruction of chronic rotator cuff tears in rats. Study design: Controlled laboratory study. Methods: A total of 32 male Sprague-Dawley rats underwent unilateral (left) supraspinatus tenotomy with delayed transosseous rotator cuff reconstruction after 3 weeks. All rats were sacrificed 8 weeks after rotator cuff repair. Animals were randomly assigned to 1 of 2 groups. At 1 day after rotator cuff reconstruction, the intervention group was treated with a single subcutaneous dose of zoledronic acid at 100 µg/kg bodyweight, and the control group received 1 mL of subcutaneous saline solution. In 12 animals of each group, micro-computed tomography scans of both shoulders were performed as well as biomechanical testing of the supraspinatus enthesis of both sides. In 4 animals of each group, histological analyses were conducted. Results: In the intervention group, bone volume fraction (bone volume/total volume [BV/TV]) of the operated side was higher at the lateral humeral head (P = .005) and the medial humeral head (P = .010) compared with the control group. Trabecular number on the operated side was higher at the lateral humeral head (P = .004) and the medial humeral head (P = .001) in the intervention group.

To better understand the biomechanical effect of matrix elasticity on the formation of articular cartilage analogs in vitro, this study aims at assessing the redifferentiation capacity of primary human chondrocytes in three different hydrogel matrices of predefined matrix elasticities. The hydrogel elasticities were chosen to represent a broad spectrum of tissue stiffness ranging from very soft tissues with a Young's modulus of 1 kPa up to elasticities of 30 kPa, representative of the perichondral-space. In addition, the interplay of matrix elasticity and transforming growth factor beta-3 (TGF-β3) on the redifferentiation of primary human articular chondrocytes was studied by analyzing both qualitative (viability, morphology, histology) and quantitative (RT-qPCR, sGAG, DNA) parameters, crucial to the chondrotypic phenotype.

However, glyphosate is discussed as showing genotoxicity and many other side-effects such as inhibiting the mitochondrial succinate dehydrogenase, leading to a decreased ATP production. Therefore, finding alternative active substances is necessary. Pelargonic acid (nonanoic acid) and its ammonium salt (saponified form), which are used as alternatives to glyphosate-based herbicides, are biological derived substances considered as environmentally friendly herbicides. To test the effects of pelargonic acid in its acidic form (active substance in TopGun) and its saponified form (in Finalsan Plus) on the aquatic ecosystem, students of the master study program "environmental management and ecotoxicology" compared the toxicity levels of these substances using zebrafish embryos within the scope of a student research course. The project was developed by applying the 7-step problem-based learning method which allowed the students to design their experiments independently with the guidance and feedback of the lecturers. Acute toxicity was determined according to OECD test guideline 236 in D. rerio which revealed a LC50 of 1.55 mg/L of pelargonic acid, a LC50 value of 0.93 mg/L pelargonic acid in TopGun and a LC50 of 36.37 mg/L of Finalsan Plus. Neutral Red Uptake assays were performed on the rainbow trout-derived gill cell-line RTgill-W1 to determine the acute toxicity according to the OECD test guideline 129 which revealed the IC50 value of 12.4 mg/L pelargonic acid in TG. Due to solubility limits, no reliable IC50 could be obtained. The results of the tests indicate differences in the acute toxicity of the pelargonic acid-based formulations TopGun and Finalsan Plus.

In recent years, injectable and highly tunable composite hydrogels for cartilage tissue engineering and drug delivery have been introduced as a desirable alternative to invasive treatments. In this study, we aimed to formulate injectable hydrogels for drug delivery and cartilage tissue engineering by combining different concentrations of hyaluronic acid-tyramine (HA-Tyr) with regenerated silk-fibroin (SF) solutions. Upon enzymatic crosslinking, the gelation and mechanical properties were characterized over time. To evaluate the effect of the hydrogel compositions and properties on extracellular matrix (ECM) deposition, bovine chondrocytes were embedded in enzymatically crosslinked HA-Tyr/SF composites (in further work abbreviated as HA/SF) or HA-Tyr hydrogels. We demonstrated that all hydrogel formulations were cytocompatible and could promote the expression of cartilage matrix proteins allowing chondrocytes to produce ECM, while the most prominent chondrogenic effects were observed in hydrogels with HA20/SF80 polymeric ratios. Unconfined mechanical testing showed that the compressive modulus for HA20/SF80 chondrocyte-laden constructs was increased almost 10-fold over 28 days of culture in chondrogenic medium which confirmed the superior production of ECM in this hydrogel compared to other hydrogels in this study. Furthermore, in hydrogels loaded with anabolic and anti-inflammatory drugs, HA20/SF80 hydrogel showed the longest and the most sustained release profile over time which is desirable for the long treatment duration typically necessary for osteoarthritic joints. In conclusion, HA20/SF80 hydrogel was successfully established as a suitable injectable biomaterial for cartilage tissue engineering and drug delivery applications.}, subject = {Tissue Engineering}, language = {en} } @article{FrohnerMenseKrondrafetal., author = {Frohner, Matthias and Mense, Alexander and Krondraf, Nikolaus and Sabutsch, Stefan}, title = {Implementierungsleitfaden HL7 Implementation Guide for CDA® R2: Implementierungsleitfaden Meldung an das Epidemiologische Meldesystem (EMS) - Labor-und Arztmeldung, ELGA GmbH}, series = {ELGA CDA Implementierungsleitf{\"a}den HL7}, volume = {2020}, journal = {ELGA CDA Implementierungsleitf{\"a}den HL7}, subject = {eHealth}, language = {de} } @article{FrohnerSabutschKrondraf, author = {Frohner, Matthias and Sabutsch, Stefan and Krondraf, Nikolaus}, title = {ELGA CDA Implementierungsleitf{\"a}den HL7 Implementation Guide for CDA® R2: Ambulanzbefund, ELGA GmbH}, series = {ELGA CDA Implementierungsleitf{\"a}den HL7}, volume = {2020}, journal = {ELGA CDA Implementierungsleitf{\"a}den HL7}, subject = {eHealth}, language = {de} } @inproceedings{EckeltMally, author = {Eckelt, Markus and Mally, Franziska}, title = {Running Shoes—Possible Correlations of Biomechanical and Material Tests.}, series = {ISEA 2020 Online - Proceedings 2020, 49(1)}, booktitle = {ISEA 2020 Online - Proceedings 2020, 49(1)}, pages = {25 -- 25}, subject = {Sports Equipment Technologies}, language = {en} } @inproceedings{EckeltMally, author = {Eckelt, Markus and Mally, Franziska}, title = {Use of Acceleration Sensors in Archery}, series = {ISEA 2020 Online - Proceedings 2020, 49(1)}, booktitle = {ISEA 2020 Online - Proceedings 2020, 49(1)}, pages = {98 -- 98}, subject = {Sports Equipment Technologies}, 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{FeichtingerMonforteKeibletal., author = {Feichtinger, Xaver and Monforte, Xavier and Keibl, Claudia and Hercher, David and Schanda, Jakob and Teuschl, Andreas and Muschitz, Christian and Redl, Heinz and Fialka, Christian and Mittermayr, Rainer}, title = {Substantial Biomechanical Improvement by Extracorporeal Shockwave Therapy After Surgical Repair of Rodent Chronic Rotator Cuff Tears.}, series = {American Journal of Sports Medicine}, journal = {American Journal of Sports Medicine}, subject = {Shockwave Therapy}, language = {en} } @article{TeuschlTanglHeimeletal., author = {Teuschl, Andreas and Tangl, Stefan and Heimel, Patrick and Schwarze, Uwe Yacine and Monforte, Xavier and Redl, Heinz and Nau, Thomas}, title = {Osteointegration of a Novel Silk Fiber-Based ACL Scaffold by Formation of a Ligament-Bone Interface.}, series = {American Journal of Sports Medicine}, journal = {American Journal of Sports Medicine}, subject = {Tissue Engineering}, language = {en} } @article{SimsaMonforteSalzeretal., author = {Simsa, Robin and Monforte, Xavier and Salzer, Elias and Teuschl, Andreas and Jenndahl, Lachmi and Bergh, Niklas and Fogelstrand, Per}, title = {Effect of fluid dynamics on decellularization efficacy and mechanical properties of blood vessels.}, series = {PLoS One}, journal = {PLoS One}, subject = {Tissue Engineering}, language = {en} } @article{JesenbergerZmajkovicovaCatalanottietal., author = {Jesenberger, Veronika and Zmajkovicova, Katarina and Catalanotti, Federica and Baumgartner, Christian and Reyes, Gloria Ximena and Baccarini, Manuela}, title = {MEK1 is required for PTEN membrane recruitment, AKT regulation, and the maintenance of peripheral tolerance}, series = {Mol.

MEK1 ablation stabilizes AKT activation and, in vivo, causes a lupus-like autoimmune disease and myeloproliferation. Mechanistically, MEK1 is necessary for PTEN membrane recruitment as part of a ternary complex containing the multidomain adaptor MAGI1. Complex formation is independent of MEK1 kinase activity but requires phosphorylation of T292 on MEK1 by activated ERK. Thus, inhibiting the ERK pathway reduces PTEN membrane recruitment, increasing phosphatidylinositol-3-phosphate accumulation and AKT activation.

Mek1 mediates the regulation of Mek2 in the context of a previously undiscovered Mek1-Mek2 complex.

The well established standard procedure of autologous tissue transplantation stabilizes the knee and allows sport activities after 9-12 months. However, harvest of autologous tissue such as patellar tendon or semitendinosus (the most frequently used autograft) weakens other body areas and long term data show an increased rate of arthroses (up to 50\% after 10 years) associated with ACL reconstructions. Based on numerous preclinical data and data from a 12-month sheep study the scale-up as well as regulatory approval process of a novel textile engineered silk implant as ACL graft have been initiated. It is planned to enter a clinical trial and strive for regulatory approval as a medical class 3 implant. The sheep data (1) have revealed an approximately 50\% degradation of the purified medical silk, which acts as scaffold for the regrowth of a new endogenous ligament. The formation of oriented collagenous tissue fibers including vascularization proves a ligament tissue regeneration for the first time. Scale-up and implementation of a commercial process require a defined set of specifications of commercial silkworm (Bombyx mori) silk, a biological raw material sourced from the textile industry as well as adequate analytical methods to characterize the depletion of sericin in the course of the production process. Based on first full scale samples, the defined biocompatibility program has to be executed, in the EU following the ISO requirements of the notified bodies, in the USA determined by the FDA. Upon submission of the full technical documentation as well as the biocompati-bility data, approval of a clinical trial can be achieved in order to demonstrate the clinical efficacy of the silk based ACL graft compared to the gold standard method in two different randomized groups. As primary endpoint the knee stability will be tested by an apparatus supported Lachmann test. In this study, besides the clinical benefit the patient safety is an important goal. The results of this study will be used for achievement of regulatory approval. References: 1) Teuschl A, Heimel P, N{\"u}rnberger S, van Griensven M, Redl H, Nau T. Am. J.

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} } @article{SlezakSlezakHartingeretal., author = {Slezak, Paul and Slezak, Cyrill and Hartinger, Joachim and Teuschl, Andreas and N{\"u}rnberger, Sylvia and Redl, Heinz and Mittermayr, Rainer}, title = {A Low Cost Implantation Model in the Rat That Allows a Spatial Assessment of Angiogenesis.}, series = {Frontiers in Bioengineering and Biotechnology}, journal = {Frontiers in Bioengineering and Biotechnology}, abstract = {There is continual demand for animal models that allow a quantitative assessment of angiogenic properties of biomaterials, therapies, and pharmaceuticals.

We have refined an implantation model and paired it with a computational analytic routine which outputs not only vessel count but also vessel density, distribution, and vessel penetration depth, that relies on a centric vessel as a reference point. We have successfully validated our model by characterizing the angiogenic potential of a fibrin matrix in conjunction with recombinant human vascular endothelial growth factor (rhVEGF165). The inferior epigastric vascular pedicles of rats were sheathed with silicone tubes, which were subsequently filled with 0.2 ml of fibrin and different doses of rhVEGF165, centrically embedding the vessels. Over 4 weeks, tissue samples were harvested and subsequently immunohistologically stained and computationally analyzed. The model was able to detect variations over the angiogenic potentials of growth factor spiked fibrin matrices. Adding 20 ng of rhVEGF165 resulted in a significant increase in vasculature while 200 ng of rhVEGF165 did not improve vascular growth. Vascularized tissue volume increased during the first week and vascular density increased during the second week. Total vessel count increased significantly and exhibited a peak after 2 weeks which was followed by a resorption of vasculature by week 4.

Although abandoned in the past, primary repair with conservation of the original ligament demonstrates considerable advantages compared to reconstruction. We hypothesized that early repair, strictly limited to patients with a proximal ACL rupture and excellent tissue quality of the remaining ACL stump, would lead to equal revision rates and subjective outcomes as reported for ACL reconstruction after a minimum of 5 years. Methods: In this questionnaire study, patients who had a primary ACL repair between 2002 and 2009 were invited to participate. Besides any potential revision surgery, the Tegner activity scale and the Knee Injury and Osteoarthritis Outcome Score were included in the evaluation. Results: Out of 1912 patients who had ACL related surgery during the observation period, 221 (11.4\%) had a primary ACL repair. 60 patients (61 knees) were available for follow-up. In 2/61 (3.3\%) cases ACL revision surgery was performed and one patient had meniscus surgery of the affected side. The median Tegner activity scale was 6 (range, 3 to 10). The mean KOOS subscores were 88.8\% (Function/Sports), 86.6\% (Quality of life), 94.6 (Symptoms), 94.0 (Pain) and 97.0 (Activities of Daily Living).

Ihr zerst{\"o}rerisches Potential wird seit den 1980-ern zur Behandlung und Desintegration von Nierensteinen angewendet, wo die Stoßwellentherapie heutzutage die Standardbehandlung darstellt. Der erste unerwartete Effekt der Therapie - die Verdichtung des Beckenkammes - wurde schon damals bei Folgeuntersuchungen von Patienten mit Nierensteinen festgestellt. Die Beobachtung, dass Stoßwellen Effekte auf Knochen hervorrufen, ebnete den Weg f{\"u}r die Anwendung der Stoßwellentherapie in Bereichen abseits der Urologie. Mittlerweile wird die Stoßwellentherapie nicht nur zur Behandlung von Knochenbruchheilungsst{\"o}rungen und Tendinopathien, sondern auch bei Weichteilwundheilungsst{\"o}rungen eingesetzt. Trotz der vielf{\"a}ltigen Anwendungsgebiete ist der zugrunde liegende Wirkungsmechanismus des positiven Effekts der Stoßwellentherapie bis heute noch nicht vollst{\"a}ndig aufgekl{\"a}rt. Die Aktivierung von mechanotransduktiven Signalwegen wurde bereits teilweise in vitro und in vivo gezeigt, jedoch meist bei kn{\"o}chernen Indikationen. Doch auch f{\"u}r die Anwendung der Stoßwellentherapie in der (verz{\"o}gerten) Wundheilung ist die Aufkl{\"a}rung des Wirkungsmechanismus essentiell. Erst dadurch k{\"o}nnte diese nicht- invasive, effiziente und großteils Nebenwirkungs-freie Therapieform auch in diesem Bereich als m{\"o}gliche Standardtherapieform genutzt werden. In dieser Dissertation wurde zuerst ein Set-up zur in vitro Stoßwellenanwendung optimiert. Mithilfe eines Molek{\"u}l-Aufnahme Assays wurden die technischen Parameter f{\"u}r die in vitro Stoßwellenbehandlung festgelegt. Mit diesem in vitro Aufbau sollten daraufhin jene intrazellul{\"a}ren Mechanismen identifiziert werden, die von der Stoßwelle beeinflusst werden. In einem in vivo Modell sollte schlussendlich die Rolle dieser Mechanismen am wundheilungsf{\"o}rdernden Effekt der Stoßwelle gekl{\"a}rt werden. Um m{\"o}glichst universelle Effekte der Stoßwelle auf intrazellul{\"a}re Signalwege zu untersuchen, wurden verschiedenste Zelllinien verwendet. Diese beinhalteten die humane U937 Monozyten Zelllinie, humane Jurkat T-Zellen, die humane MG63 Osteosarcoma Zelllinie, die murine C3H10T1/2 mesenchymale Progenitor Zelllinie sowie prim{\"a}re humane mononukle{\"a}re Zellen des peripheren Blutes. Die in den proliferativen Effekt der Stowellentherapie involvierte Signalkaskade konnte darauffolgend erstmals sowohl in murinen C3H10T1/2 Zellen als auch in humanen Fettstammzellen (adipose tissue-derived stem cells) und in humanen Jurkat T-Zellen detailliert beschrieben werden. Außerdem wurde ATP als entscheidendes Signalmolek{\"u}l identifiziert, welches nach Freisetzung durch Stoßwellenbehandlung mittels purinergem Signaling die Erk1/2 Signalkaskade aktiviert. F{\"u}r die dadurch gesteigerte Proliferation in stoßwellenbehandelten Zellen ist die Erk1/2 Aktivierung essentiell. In einem in vivo Model f{\"u}r gest{\"o}rte Wundheilung in der Ratte wurde die Hypothese zur entscheidenden Rolle des Erk1/2 Signalweges im wundheilungsf{\"o}rdernden Effekt der Stoßwelle best{\"a}tigt. In dieser Dissertation wurde gezeigt, dass die durch purinerges Signaling aktivierte Erk1/2 Signalkaskade eine entscheidende Rolle in der durch Stoßwellentherapie beschleunigten Zellproliferation in vitro und Wundheilung in vivo {\"u}bernimmt. Das damit erweiterte Verst{\"a}ndnis der Wirkungsmechanismen der Stoßwellentherapie kann zur Weiterentwicklung dieser Behandlungsform als zuk{\"u}nftige Standardtherapie bei Wundheilungsst{\"o}rungen,

activation of the Ras-mitogen-activated protein kinase (MAPK) pathway. Conversely, the structurally related phosphatase SHP-1 is predominantly expressed in hemopoietic cells and becomes tyrosine phosphorylated upon colony-stimulating factor 1 treatment of macrophages without associating with the colony-stimulating factor 1 receptor tyrosine kinase. Mice lacking functional SHP-1 (me/me and me(v)/me(v)) develop systemic autoimmune disease with accumulation of macrophages, suggesting that SHP-1 may be a negative regulator of hemopoietic cell growth. By using macrophages expressing dominant negative Ras and the me(v)/me(v) mouse mutant, we show that SHP-1 is activated in the course of mitogenic signal transduction in a Ras-dependent manner and that its activity is necessary for the Ras-dependent activation of the MAPK pathway but not of the Raf-1 kinase. Consistent with a role for SHP-1 as an intermediate between Ras and the MEK-MAPK pathway, Ras-independent activation of the latter kinases by bacterial lipopolysaccharide occurred normally in me(v)/me(v) cells. Our results sharply accentuate the diversity of signal transduction in mammalian cells, in which the same signaling intermediates can be rearranged to form different pathways.}, subject = {Molecular Cell Biology}, language = {en} } @article{ReichelHaumerSchretteretal., author = {Reichel, Martin and Haumer, A. and Schretter, H. and Sabo, Anton}, title = {Development of a Measurement-Prosthesis for a Ski Boot Test Bench}, series = {The Engineering of Sport}, volume = {Vol. 1}, journal = {The Engineering of Sport}, number = {7}, pages = {255 -- 262}, subject = {Sport}, language = {en} } @article{SticklerMartinekRattay, author = {Stickler, Yvonne and Martinek, Johannes and Rattay, Frank}, title = {Modeling Needle Stimulation of Denervated Muscle Fibers: Voltage-Distance Relations and Fiber Polarization Effects}, series = {IEEE Transactions on Biomedical Engineering / IEEE Engineering in Medicine and Biology Society}, volume = {Vol. 56}, journal = {IEEE Transactions on Biomedical Engineering / IEEE Engineering in Medicine and Biology Society}, number = {issue 10}, subject = {Muscle Stimulation}, language = {en} } @article{SticklerMartinekReicheletal., author = {Stickler, Yvonne and Martinek, Johannes and Reichel, Martin and Rattay, Frank}, title = {Modeling the excitability of the denervated human thigh for the stimulation with surface and needle electrodes}, series = {Basic Applied Myology}, volume = {Vol. 19}, journal = {Basic Applied Myology}, number = {Issue 5}, pages = {237 -- 242}, subject = {Electric Stimulation}, language = {en} } @article{JesenbergerProcykYuanetal., author = {Jesenberger, Veronika and Procyk, Katarzyna and Yuan, Junying and Reipert, Siegfried and Baccarini, Manuela}, title = {Salmonella-induced caspase-2 activation in macrophages: a novel mechanism in pathogen-mediated apoptosis}, series = {J Exp Med.}, volume = {2000}, journal = {J Exp Med.}, number = {192(7)}, doi = {10.1084/jem.192.7.1035}, pages = {1035 -- 1046}, abstract = {The enterobacterial pathogen Salmonella induces phagocyte apoptosis in vitro and in vivo. These bacteria use a specialized type III secretion system to export a virulence factor, SipB, which directly activates the host's apoptotic machinery by targeting caspase-1. Caspase-1 is not involved in most apoptotic processes but plays a major role in cytokine maturation. We show that caspase-1-deficient macrophages undergo apoptosis within 4-6 h of infection with invasive bacteria. This process requires SipB, implying that this protein can initiate the apoptotic machinery by regulating components distinct from caspase-1. Invasive Salmonella typhimurium targets caspase-2 simultaneously with, but independently of, caspase-1. Besides caspase-2, the caspase-1-independent pathway involves the activation of caspase-3, -6, and -8 and the release of cytochrome c from mitochondria, none of which occurs during caspase-1-dependent apoptosis. By using caspase-2 knockout macrophages and chemical inhibition, we establish a role for caspase-2 in both caspase-1-dependent and -independent apoptosis. Particularly, activation of caspase-1 during fast Salmonella-induced apoptosis partially relies on caspase-2. The ability of Salmonella to induce caspase-1-independent macrophage apoptosis may play a role in situations in which activation of this protease is either prevented or uncoupled from the induction of apoptosis.}, subject = {caspase-2 activation in macrophages}, language = {en} } @article{JesenbergerProcykRuethetal., author = {Jesenberger, Veronika and Procyk, Katarzyna and R{\"u}th, Jochen and Schreiber, Martin and Theussl, Hans Christian and Wagner, Erwin and Baccarini, Manuela}, title = {Protective Role of Raf-1 in Salmonella-Induced Macrophage Apoptosis}, series = {J Exp Med.}, volume = {2001}, journal = {J Exp Med.}, number = {193(3)}, doi = {10.1084/jem.193.3.353}, pages = {353 -- 364}, abstract = {Invasive Salmonella induces macrophage apoptosis via the activation of caspase-1 by the bacterial protein SipB. Here we show that infection of macrophages with Salmonella causes the activation and degradation of Raf-1, an important intermediate in macrophage proliferation and activation. Raf-1 degradation is SipB- and caspase-1-dependent, and is prevented by proteasome inhibitors. To study the functional significance of Raf-1 in this process, the c-raf-1 gene was inactivated by Cre-loxP-mediated recombination in vivo. Macrophages lacking c-raf-1 are hypersensitive towards pathogen-induced apoptosis. Surprisingly, activation of the antiapoptotic mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) and nuclear factor κB pathways is normal in Raf-1-deficient macrophages, and mitochondrial fragility is not increased. Instead, pathogen-mediated activation of caspase-1 is enhanced selectively, implying that Raf-1 antagonizes stimulus-induced caspase-1 activation and apoptosis.}, subject = {Salmonella-Induced Macrophage Apoptosis}, language = {en} } @article{JesenbergerJentsch, author = {Jesenberger, Veronika and Jentsch, Stefan}, title = {Deadly encounter: ubiquitin meets apoptosis}, series = {Nat Rev Mol Cell Biol.}, volume = {2002}, journal = {Nat Rev Mol Cell Biol.}, number = {3(2)}, doi = {https://doi.org/10.1038/nrm731}, pages = {112 -- 121}, abstract = {The ubiquitin/proteasome pathway is the main non-lysosomal route for intracellular protein degradation in eukaryotes.

We focus, in particular, on the ethical component of FAIRER (Findable, Accessible, Interoperable, Ethical, and Reproducible) data, and the pseudo-anonymization and anonymization of COVID-19 datasets to protect personally identifiable information (PII). First we consider the need for the customisation of the existing privacy preservation techniques in the context of rapid production, integration, sharing and analysis of COVID-19 data. Second, the methods for the pseudo-anonymization of direct identification variables are discussed. We also discuss different pseudo-IDs of the same person for multi-domain and multi-organization. Essentially, pseudo-anonymization and its encrypted domain specific IDs are used to successfully match data later, if required and permitted, as well as to restore the true ID (and authenticity) in individual cases of a patient's clarification.Third, we discuss application of statistical disclosure control (SDC) techniques to COVID-19 disease data. To assess and limit the risk of re-identification of individual persons in COVID-19 datasets (that are often enriched with other covariates like age, gender, nationality, etc.) to acceptable levels, the risk of successful re-identification by a combination of attribute values must be assessed and controlled. This is done using statistical disclosure control for anonymization of data. Lastly, we discuss the limitations of the proposed techniques and provide general guidelines on using disclosure risks to decide on appropriate modes for data sharing to preserve the privacy of the individuals in the datasets.}, subject = {COVID19}, language = {en} } @misc{LeitnerSauermann, author = {Leitner, Rita and Sauermann, Stefan}, title = {Erreichen „harmonisierter Empfehlungen": von Studierenden generierte Fragen als Ausgangspunkt f{\"u}r evidenzbasierte Argumentation von Stakeholder-Sichtweisen - ein problem-based learning Ansatz}, subject = {Problem Based Learning}, language = {de} } @inproceedings{LitzenbergerChristensenHofstaetteretal., author = {Litzenberger, Stefan and Christensen, Troels and Hofst{\"a}tter, Otto and Sabo, Anton}, title = {Prediction of Road Surface Quality during Cycling Using Smartphone Accelerometer Data}, series = {12th Conference of the International Sports Engineering Association}, booktitle = {12th Conference of the International Sports Engineering Association}, subject = {Cycling}, language = {en} } @inproceedings{GerbovicsHallerBittermannetal., author = {Gerbovics, Ferenc and Haller, Michael and Bittermann, Mark and Urbauer, Philipp and Frohner, Matthias and Pohn, Birgit and Sauermann, Stefan and Mense, Alexander}, title = {ADVANCEMENT OF A WEARABLE HEALTH DATA HUB-PROTOTYPE FOR CONTEXT BASED TELEMONITORING USING STANDARDIZED DATA TRANSFER METHODS}, series = {Tagungsband der eHealth und eHealth Benchmarking, Wien}, booktitle = {Tagungsband der eHealth und eHealth Benchmarking, Wien}, subject = {Health data}, language = {en} } @inproceedings{SauermannReichelBijaketal., author = {Sauermann, Stefan and Reichel, Martin and Bijak, Manfred and Unger, Ewald and Rafolt, D. and Mayr, Winfried and Lanm{\"u}ller, Hermann}, title = {BioSignalizer: Data acquisition and analysis for experimental and clinical applications}, series = {IFMBE Proceedings / Vienna, Austria, Verein zur Veranstaltung der EMBEC}, booktitle = {IFMBE Proceedings / Vienna, Austria, Verein zur Veranstaltung der EMBEC}, pages = {408 -- 409}, subject = {Data Analysis}, language = {en} } @article{IllesHassmannHrenetal., author = {Illes, Sandrina and Hassmann, Michaela and Hren, Martin and Ilagan, Reynaldo and Litzenberger, Stefan and Sabo, Anton}, title = {Influence of pedalling with the metatarsus on running characteristics in triathlon competition}, series = {Procedia Engineering}, volume = {2010}, journal = {Procedia Engineering}, number = {Vol. 2 (2)}, pages = {3127 -- 3131}, subject = {Sport}, language = {en} } @inproceedings{SaboKafkaLitzenbergeretal., author = {Sabo, Anton and Kafka, Patricia and Litzenberger, Stefan and Sabo, Christoph}, title = {The Engineering of Sport 8 - Engineering Emotion}, series = {Procedia Engineering}, booktitle = {Procedia Engineering}, subject = {Sport}, language = {en} } @article{HuberGriesIlkRuenzleretal., author = {Huber-Gries, Carina and Ilk, Nicola and R{\"u}nzler, Dominik and Egelseer, Eva-Maria and Weigert, Stefan and Sleytr, Uwe}, title = {The three S-layer-like homology motifs of the S-layer protein SbpA of Bacillus sphaericus CCM 2177 are not sufficient for binding to the pyruvylated secondary cell wall polymer}, series = {Molecular Microbiology}, volume = {55}, journal = {Molecular Microbiology}, number = {1}, pages = {197 -- 205}, subject = {Proteins}, language = {en} } @misc{ThieleKafkaLitzenbergeretal., author = {Thiele, Gerrit and Kafka, Patricia and Litzenberger, Stefan and Sabo, Anton}, title = {Ontrack measurements in motocross: The correlation of neck muscle activity and contact incidents of helmet and neck brace}, subject = {Motocross}, language = {en} } @article{TomaschMaleinerHromadaetal., author = {Tomasch, Janine and Maleiner, Babette and Hromada, Carina and Szwarc-Hofbauer, Dorota and Teuschl-Woller, Andreas}, title = {Cyclic Tensile Stress Induces Skeletal Muscle Hypertrophy and Myonuclear Accretion in a 3D Model}, series = {Tissue Eng.

This extends to research software sharing, in recognition of the key role in software in analysing data. The work has been divided into four research areas (namely, clinical, omics, epidemiology, social sciences) with four cross cutting themes (namely, community participation, indigenous data, legal and ethical considerations, research software), as a way to focus the conversations, and provide an initial set of guidelines in a tight timeframe. The detailed guidelines are aimed to help stakeholders follow best practices to maximise the efficiency of their work, and to act as a blueprint for future emergencies. The recommendations in the document are aimed at helping policymakers and funders to maximise timely, quality data sharing and appropriate responses in such health emergencies.

This paper introduces an alternative approach of simulating and evaluating patient-ventilator interactions with high fidelity using the electromechanical lung simulator xPULM™. The xPULM™ approximates respiratory activities of a patient during alternating phases of spontaneous breathing and apnea intervals while connected to a mechanical ventilator. Focusing on different triggering events, volume assist-control (V/A-C) and pressure support ventilation (PSV) modes were chosen to test patient-ventilator interactions. In V/A-C mode, a double-triggering was detected every third breathing cycle, leading to an asynchrony index of 16.67\%, which is classified as severe. This asynchrony causes a significant increase of peak inspiratory pressure (7.96 ± 6.38 vs. 11.09 ± 0.49 cmH2O, p < 0.01)) and peak expiratory flow (-25.57 ± 8.93 vs. 32.90 ± 0.54 L/min, p < 0.01) when compared to synchronous phases of the breathing simulation. Additionally, events of premature cycling were observed during PSV mode. In this mode, the peak delivered volume during simulated spontaneous breathing phases increased significantly (917.09 ± 45.74 vs. 468.40 ± 31.79 mL, p < 0.01) compared to apnea phases. Various dynamic clinical situations can be approximated using this approach and thereby could help to identify undesired patient-ventilation interactions in the future. Rapidly manufactured ventilator systems could also be tested using this approach.

The objective of this work is to experimentally investigate changes in aerosol particle diameter and particle number concentration of pharmaceutical aerosols generated by four dry powder inhalers under realistic inhalation and exhalation conditions. To simulate patients undergoing inhalation therapy, the active respiratory system model (xPULM™) was used. A mechanical upper airway model was developed, manufactured, and introduced as a part of the xPULM™ to represent the human upper respiratory tract with high fidelity. Integration of optical aerosol spectrometry technique into the setup allowed for evaluation of pharmaceutical aerosols. The results show that there is a significant difference (p < 0.05) in mean particle diameter between inhaled and exhaled particles with the majority of the particles depositing in the lung, while particles with the size of (>0.5 μm) are least influenced by deposition mechanisms. The fraction of exhaled particles ranges from 2.13\% (HandiHaler®) over 2.94\% (BreezHaler®), and 6.22\% (Turbohaler®) to 10.24\% (Ellipta®). These values are comparable to previously published studies. Furthermore, the mechanical upper airway model increases the resistance of the overall system and acts as a filter for larger particles (>3 μm). In conclusion, the xPULM™ active respiratory system model is a viable option for studying interactions of pharmaceutical aerosols and the respiratory tract regarding applicable deposition mechanisms. The model strives to support the reduction of animal experimentation in aerosol research and provides an alternative to experiments with human subjects.}, subject = {Biomedical Engineering}, language = {en} } @article{PastekaForjanSauermannetal., author = {Pasteka, Richard and Forjan, Mathias and Sauermann, Stefan and Drauschke, Andreas}, title = {Electro-mechanical Lung Simulator Using Polymer and Organic Human Lung Equivalents for Realistic Breathing Simulation}, series = {Scientific Reports}, volume = {Vol 9}, journal = {Scientific Reports}, number = {No. 1}, pages = {Article number: 19778}, abstract = {Simulation models in respiratory research are increasingly used for medical product development and testing, especially because in-vivo models are coupled with a high degree of complexity and ethical concerns. This work introduces a respiratory simulation system, which is bridging the gap between the complex, real anatomical environment and the safe, cost-effective simulation methods. The presented electro-mechanical lung simulator, xPULM, combines in-silico, ex-vivo and mechanical respiratory approaches by realistically replicating an actively breathing human lung. The reproducibility of sinusoidal breathing simulations with xPULM was verified for selected breathing frequencies (10-18 bpm) and tidal volumes (400-600 ml) physiologically occurring during human breathing at rest. Human lung anatomy was modelled using latex bags and primed porcine lungs. High reproducibility of flow and pressure characteristics was shown by evaluating breathing cycles (nTotal = 3273) with highest standard deviation |3σ| for both, simplified lung equivalents (μV˙ = 23.98 ± 1.04 l/min, μP = -0.78 ± 0.63 hPa) and primed porcine lungs (μV˙ = 18.87 ± 2.49 l/min, μP = -21.13 ± 1.47 hPa).

Experimental measurements are performed and simulation results mutually compared using the electro-mechanical lung simulator xPULM. The inhalatory waveforms are repeatably simulated with high fidelity in regards to the waveform shape with the lowest value of the Goodness of fit 0.89. Additionally, the measured values for all characteristic inhalatory parameters are simulated with low standard deviation < 1. The differences between the required and measured waveform shapes are small, < 3 L/min and do not influence the overall inhalatory volume.

Scaffold materials currently used in clinical settings have shown limitations in providing suitable biomechanical properties and an authentic and protective environment for regenerative cells. To tackle this problem, we developed a scaffold material based on decellularised human articular cartilage. Methods: Human articular cartilage matrix was engraved using a CO2 laser and treated for decellularisation and glycosaminoglycan removal. Characterisation of the resulting scaffold was performed via mechanical testing, DNA and GAG quantification and in vitro cultivation with adipose-derived stromal cells (ASC). Cell vitality, adhesion and chondrogenic differentiation were assessed. An ectopic, unloaded mouse model was used for the assessment of the in vivo performance of the scaffold in combination with ASC and human as well as bovine chondrocytes. The novel scaffold was compared to a commercial collagen type I/III scaffold. Findings: Crossed line engravings of the matrix allowed for a most regular and ubiquitous distribution of cells and chemical as well as enzymatic matrix treatment was performed to increase cell adhesion. The biomechanical characteristics of this novel scaffold that we term CartiScaff were found to be superior to those of commercially available materials. Neo-tissue was integrated excellently into the scaffold matrix and new collagen fibres were guided by the laser incisions towards a vertical alignment, a typical feature of native cartilage important for nutrition and biomechanics. In an ectopic, unloaded in vivo model, chondrocytes and mesenchymal stromal cells differentiated within the incisions despite the lack of growth factors and load, indicating a strong chondrogenic microenvironment within the scaffold incisions. Cells, most noticeably bone marrow-derived cells, were able to repopulate the empty chondrocyte lacunae inside the scaffold matrix. Interpretation: Due to the better load-bearing, its chondrogenic effect and the ability to guide matrix-deposition, CartiScaff is a promising biomaterial to accelerate rehabilitation and to improve long term clinical success of cartilage defect treatment.

Biocompatibility was tested in vitro by culturing the grafts with primary human macrophages and in vivo by subcutaneous implantation of graft conduits (n = 7 per group) into the flanks of nude rats. Subsequently, graft performance was evaluated using an aortic implantation model in Sprague Dawley rats (one month, n = 14). In situ graft imaging was performed using MRI angiography. Retrieved specimens were analyzed by electromyography, scanning electron microscopy, histology and immunohistochemistry to evaluate cell migration and the degree of functional tissue remodeling. Both decellularization methods resulted in grafts of excellent biocompatibility in vitro and in vivo, with low immunogenic potential. Proteomic data revealed removal of cytoplasmic proteins with relative enrichment of ECM proteins in decelluarized specimens of both groups. Noteworthy, LC-Mass Spectrometry analysis revealed that 16 proteins were exclusively preserved in Triton decellularized specimens in comparison to SDS-treated specimens. Aortic grafts showed high patency rates, no signs of thrombus formation, aneurysms or rupture. Conduits of both groups revealed tissue-specific cell migration indicative of functional remodeling. This study strongly suggests that decellularized allogenic grafts from the human placenta have the potential to be used as vascular replacement materials. Both detergents produced grafts with low residual immunogenicity and appropriate mechanical properties.

In this study we demonstrate the use of "AuriScaff", an enzymatically perforated bovine auricular cartilage scaffold, as a novel biomaterial for repopulation with regenerative cells and for the formation of high-quality hyaline cartilage. AuriScaff features a traversing channel network, generated by selective depletion of elastic fibers, enabling uniform repopulation with therapeutic cells. The complex collagen type II matrix is left intact, as observed by immunohistochemistry, SEM and TEM. The compressive modulus is diminished, but three times higher than in the clinically used collagen type I/III scaffold that served as control. Seeding tests with human articular chondrocytes (hAC) alone and in co-culture with human adipose-derived stromal/stem cells (ASC) confirmed that the network enabled cell migration throughout the scaffold. It also guides collagen alignment along the channels and, due to the generally traverse channel alignment, newly deposited cartilage matrix corresponds with the orientation of collagen within articular cartilage. In an osteochondral plug model, AuriScaff filled the complete defect with compact collagen type II matrix and enabled chondrogenic differentiation inside the channels. Using adult articular chondrocytes from bovine origin (bAC), filling of even deep defects with high-quality hyaline-like cartilage was achieved after 6 weeks in vivo. With its composition and spatial organization, AuriScaff provides an optimal chondrogenic environment for therapeutic cells to treat cartilage defects and is expected to improve long-term outcome by channel-guided repopulation followed by matrix deposition and alignment. STATEMENT OF SIGNIFICANCE: After two decades of tissue engineering for cartilage regeneration, there is still no optimal strategy available to overcome problems such as inconsistent clinical outcome, early and late graft failures. Especially large defects are dependent on biomaterials and their scaffolding, guiding and protective function. Considering the currently used biomaterials, structure and mechanical properties appear to be insufficient to fulfill this task. The novel scaffold developed within this study is the first approach enabling the use of dense cartilage matrix, repopulate it via channels and provide the cells with a compact collagen type II environment. Due to its density, it also provides better mechanical properties than materials currently used in clinics. We therefore think, that the auricular cartilage scaffold (AuriScaff) has a high potential to improve future cartilage regeneration approaches.}, subject = {Auricular cartilage}, language = {en} } @misc{RankTraxlerBayeretal., author = {Rank, Elisabet and Traxler, Lukas and Bayer, Natascha and Reutterer, Bernd and Lux, Kirsten and Drauschke, Andreas}, title = {Reproducibility analysis of measurements with a mechanical semiautomatic eye model for evaluation of intraocular lenses}, subject = {Mechanical Eye}, language = {en} } @misc{ObergruberMehnen, author = {Obergruber, Julian and Mehnen, Lars}, title = {Development of a paraglide control system for automatic pitch stabilization to increase the passive safety}, subject = {Paragliding}, language = {en} } @phdthesis{Traxler, author = {Traxler, Lukas}, title = {Testing the Optical Quality of Intraocular Lenses Regarding Postoperative Tilt and Decentration}, publisher = {TU Wien - Fakult{\"a}t f{\"u}r Physik}, address = {Wien}, school = {Fachhochschule Technikum Wien}, subject = {Intraocular Lens}, language = {en} } @misc{TraxlerReuttererBayeretal., author = {Traxler, Lukas and Reutterer, Bernd and Bayer, Natascha and Rank, Elisabet and Krause, Sylvio and Beckert, Erik and Drauschke, Andreas}, title = {Tilt and decentration tolerance of intraocular lenses: measurements with an improved mechanical model eye}, subject = {Eye Lens}, language = {en} } @article{PriglingerSchuhSteffenhagenetal., author = {Priglinger, Eleni and Schuh, Christina and Steffenhagen, Carolin and Wurzer, Christoph and Maier, Julia and N{\"u}rnberger, Sylvia and Holnthoner, Wolfgang and Fuchs, Christiane and Suessner, Susanne and R{\"u}nzler, Dominik and Redl, Heinz and Wolbank, Susanne}, title = {Improvement of adipose tissue-derived cells by low-energy extracorporeal shock wave therapy.}, series = {Cytotherapy}, journal = {Cytotherapy}, pages = {1079 -- 1095}, abstract = {BACKGROUND: Cell-based therapies with autologous adipose tissue-derived cells have shown great potential in several clinical studies in the last decades. The majority of these studies have been using the stromal vascular fraction (SVF), a heterogeneous mixture of fibroblasts, lymphocytes, monocytes/macrophages, endothelial cells, endothelial progenitor cells, pericytes and adipose-derived stromal/stem cells (ASC) among others. Although possible clinical applications of autologous adipose tissue-derived cells are manifold, they are limited by insufficient uniformity in cell identity and regenerative potency. METHODS: In our experimental set-up, low-energy extracorporeal shock wave therapy (ESWT) was performed on freshly obtained human adipose tissue and isolated adipose tissue SVF cells aiming to equalize and enhance stem cell properties and functionality. RESULTS: After ESWT on adipose tissue we could achieve higher cellular adenosine triphosphate (ATP) levels compared with ESWT on the isolated SVF as well as the control. ESWT on adipose tissue resulted in a significantly higher expression of single mesenchymal and vascular marker compared with untreated control. Analysis of SVF protein secretome revealed a significant enhancement in insulin-like growth factor (IGF)-1 and placental growth factor (PLGF) after ESWT on adipose tissue. DISCUSSION: Summarizing we could show that ESWT on adipose tissue enhanced the cellular ATP content and modified the expression of single mesenchymal and vascular marker, and thus potentially provides a more regenerative cell population. Because the effectiveness of autologous cell therapy is dependent on the therapeutic potency of the patient's cells, this technology might raise the number of patients eligible for autologous cell transplantation.}, subject = {Shockwave Therapy}, language = {en} } @article{BachmannSpitzRothbaueretal., author = {Bachmann, Barbara and Spitz, Sarah and Rothbauer, Mario and Jordan, Christian and Purtscher, Michaela and Zirath, Helene and Schuller, Patrick and Eilenberger, Christoph and Ali, Syed Faheem and M{\"u}hleder, Severin and Priglinger, Eleni and Harasek, Michael and Redl, Heinz and Holnthoner, Wolfgang and Ertl, Peter}, title = {Engineering of three-dimensional pre-vascular networks within fibrin hydrogel constructs by microfluidic control over reciprocal cell signaling}, series = {Biomicrofluidics}, journal = {Biomicrofluidics}, subject = {Microfluidic}, language = {en} } @misc{EckeltHerczegSabo, author = {Eckelt, Markus and Herczeg, C. and Sabo, Anton}, title = {Gesundheitsf{\"o}rdernde Maßnahmen am Arbeitsplatz durch Nordic Walking}, subject = {Sport}, language = {de} } @article{CieślikBoczulaKuepcueRuenzleretal., author = {Cieślik-Boczula, Katarzyna and K{\"u}pc{\"u}, Seta and R{\"u}nzler, Dominik and Koll, Aleksander and K{\"o}hler, Gottfried}, title = {Effects of the phenolic lipid 3-pentadecylphenol on phospholipid bilayer organization}, series = {Journal of Molecular Structure}, journal = {Journal of Molecular Structure}, number = {919(1-3)}, pages = {373 -- 380}, subject = {Phospholipid Bilayer}, language = {en} } @misc{SchneiderAignerMonforteVilaetal., author = {Schneider, Karl Heinrich and Aigner, Petra and Monforte Vila, Xavier and Holnthoner, Wolfgang and Teuschl, Andreas and Bergmeister, Helga and Redl, Heinz}, title = {Naturally derived acellular small diameter vascular grafts from human placenta for reconstructive surgery}, subject = {Placenta}, language = {en} } @misc{Nemec, author = {Nemec, Iris}, title = {Current prosthetic projects and prosthetic developments}, subject = {Prosthetics}, language = {en} } @article{SchneiderRohringerKapelleretal., author = {Schneider, Karl and Rohringer, Sabrina and Kapeller, Barbara and Grasl, Christian and Kiss, Herbert and Heber, Stefan and Walter, Ingrid and Teuschl, Andreas and Podesser, Bruno K. and Bergmeister, Helga}, title = {Riboflavin-mediated photooxidation to improve the characteristics of decellularized human arterial small diameter vascular grafts}, series = {Acta Biomater.}, volume = {2020}, journal = {Acta Biomater.}, number = {116}, pages = {246 -- 258}, abstract = {Vascular grafts with a diameter of less than 6 mm are made from a variety of materials and techniques to provide alternatives to autologous vascular grafts.

Within this system, cell-cell communication is crucial for the achievement of functional vascular network formation. Extracellular vesicles (EVs) have recently emerged as key players in cell communication by transferring bioactive molecules between cells. In this study we aimed to address the role of EVs in ASC/EC cocultures by discriminating between cells, which have received functional EV cargo from cells that have not. Therefore, we employed the Cre-loxP system, which is based on donor cells expressing the Cre recombinase, whose mRNA was previously shown to be packaged into EVs and reporter cells containing a construct of floxed dsRed upstream of the eGFP coding sequence. The evaluation of Cre induced color switch in the reporter system via EVs indicated that there is no EV-mediated RNA transmission either between EC themselves or EC and ASC. However, since Cre mRNA was not found present in EVs, it remains unclear if Cre mRNA is generally not packaged into EVs or if EVs are not taken up by the utilized cell types. Our data indicate that this technique may not be applicable to evaluate EV-mediated cell-to-cell communication in an in vitro setting using EC and ASC.

Various synthetic and natural materials were already established for use of two-dimensional (2D) and three-dimensional (3D) in vitro neovascularization assays, however, they still cannot mimic the complex functions of the sum of the extracellular matrix (ECM) in native intact tissue. Currently, this issue is only addressed by artificial products such as Matrigel™, which comprises a complex mixture of ECM proteins, extracted from animal tumor tissue. Despite its outstanding bioactivity, the isolation from tumor tissue hinders its translation into clinical applications. Since nonhuman ECM proteins may cause immune reactions, as are frequently observed in clinical trials, human ECM proteins represent the best option when aiming for clinical applications. Here, we describe an effective method of isolating a human placenta substrate (hpS) that induces the spontaneous formation of an interconnected network of green fluorescence-labeled human umbilical vein endothelial cells (gfpHUVECs) in vitro. The substrate was biochemically characterized by using a combination of bicinchoninic acid (BCA) assay, DNA, and glycosaminoglycan (GAG) content assays, sodium dodecyl sulfate/polyacrylamide gel electrophoresis (SDS-PAGE) analysis and Western blot, angiogenesis arrays, chromatographic thrombin detection, high performance liquid chromatography (HPLC)-based amino acid quantification analysis, and assessment of antimicrobial properties. 2D in vitro cell culture experiments have been performed to determine the vasculogenic potential of hpS, which demonstrated that cell networks developed on hpS show a significantly higher degree of complexity (number of tubules/junctions; total/mean tube length) when compared with Matrigel. As 3D cell culture techniques represent a more accurate representation of the in vivo condition, the substrate was 3D solidified using various natural polymers. 3D in vitro vasculogenesis assays have been performed by seeding gfpHUVECs in an hpS-fibrinogen clot. In conclusion, hpS provides a potent human/material-based alternative to xenogenic-material-based biomaterials for vascularization strategies in tissue engineering.}, subject = {Tissue Engineering}, language = {en} } @inproceedings{HoerzerFuchsGastingeretal., author = {H{\"o}rzer, S. and Fuchs, Christiane and Gastinger, R. and Sabo, Anton and Mehnen, Lars and Martinek, Johannes and Reichel, Martin}, title = {Simulation of spinning soccer ball trajectories influenced by altitude}, series = {Procedia Engineering}, booktitle = {Procedia Engineering}, pages = {2461 -- 2466}, subject = {Soccer}, language = {en} } @misc{ReuttererTraxlerBayeretal., author = {Reutterer, Bernd and Traxler, Lukas and Bayer, Natascha and Drauschke, Andreas}, title = {Further improvement of an intraocular lens holder for more physiological measurements within a mechanical eye model}, subject = {Mechanical Eye}, language = {en} } @inproceedings{ReuttererTraxlerBayeretal., author = {Reutterer, Bernd and Traxler, Lukas and Bayer, Natascha and Drauschke, Andreas}, title = {Experiments for practical education in process parameter optimization for selective laser sintering to increase workpiece quality}, series = {Proceedings of the 3rd Conference on Laser 3D Manufacturing 2016}, booktitle = {Proceedings of the 3rd Conference on Laser 3D Manufacturing 2016}, subject = {Laser Sintering}, language = {en} } @inproceedings{KneblMortonRedletal., author = {Knebl, Gerald and Morton, Tatjana J. and Redl, Heinz and R{\"u}nzler, Dominik}, title = {Mechanical stimulation of cells in 3-dimensional fibrin constructs using a bioreactor}, series = {3.

Here, we showed for the first time that the secretome of SVF cells creates an environment that triggers endothelial barrier dysfunction in early-stage lipedema.

Endothelial sprouting and vascular tube formation were significantly dependent on P2Y2 expression and inhibition of P2Y2 using a selective antagonist blocked microvascular network generation. Mechanistically, overexpression of P2Y2 in endothelial cells induced the expression of the proangiogenic molecules CXCR4, CD34, and angiopoietin-2, while expression of VEGFR-2 was decreased. Interestingly, elevated P2Y2 expression caused constitutive phosphorylation of ERK1/2 and VEGFR-2. However, stimulation of cells with the P2Y2 agonist UTP did not influence sprouting unless P2Y2 was constitutively expressed. Finally, inhibition of VEGFR-2 impaired spontaneous vascular network formation induced by P2Y2 overexpression.

Data from the Peppermint Experiment performed by proton transfer reaction mass spectrometry (PTR-MS) and selected ion flow tube mass spectrometry (SIFT-MS) are presented and discussed herein, including the product ions associated with the key peppermint volatiles, namely limonene, α- and β-pinene, 1,8-cineole, menthol, menthone and menthofuran. The breath washout profiles of these compounds from 65 individuals were collected, comprising datasets from five PTR-MS and two SIFT-MS instruments. The washout profiles of these volatiles were evaluated by comparing the log-fold change over time of the product ion intensities associated with each volatile. Benchmark values were calculated from the lower 95\% confidence interval of the linear time-to-washout regression analysis for all datasets combined. Benchmark washout values from PTR-MS analysis were 353 min for the sum of monoterpenes and 1,8-cineole (identical product ions), 173 min for menthol, 330 min for menthofuran, and 218 min for menthone; from SIFT-MS analysis values were 228 min for the sum of monoterpenes, 281 min for the sum of monoterpenes and 1,8-cineole, and 370 min for menthone plus 1,8-cineole. Large inter- and intra-dataset variations were observed, whereby the latter suggests that biological variability plays a key role in how the compounds are absorbed, metabolized and excreted from the body via breath.

To resolve these two constraints, we injected EVs directly at the lesion site acutely after spinal cord injury. We report here that intralesional application of EVs resulted in a more robust improvement of motor recovery, assessed with the BBB score and sub-score, as compared to the intravenous delivery. Moreover, the intralesional application was more potent in reducing inflammation and scarring after spinal cord injury than intravenous administration. Hence, the development of EV-based therapy for spinal cord injury should aim at an early application of vesicles close to the lesion.}, subject = {exosomes}, language = {en} } @article{FeichtingerHeimelTangletal., author = {Feichtinger, Xaver and Heimel, Patrick and Tangl, Stefan and Keibl, Claudia and N{\"u}rnberger, Sylvia and Schanda, Jakob Emanuel and Hercher, David and Kocijan, Roland and Redl, Heinz and Grillari, Johannes and Fialka, Christian and Mittermayr, Rainer}, title = {Improved biomechanics in experimental chronic rotator cuff repair after shockwaves is not reflected by bone microarchitecture}, series = {PLoS One}, volume = {17}, journal = {PLoS One}, number = {1}, doi = {10.1371/journal.pone.0262294}, subject = {chronic rotator cuff repair}, language = {en} } @phdthesis{Tomasch, author = {Tomasch, Janine}, title = {Strategies to improve the myogenic outcome of skeletal muscle tissue engineering approaches through optimization of biomaterial properties and mechanical stimuli}, school = {Fachhochschule Technikum Wien}, subject = {muscle}, language = {en} } @misc{LangerNemecKollmitzeretal., author = {Langer, Sarah and Nemec, Iris and Kollmitzer, Josef and Scherer, Matthias and Martinek, Johannes}, title = {Vergleich des decompositionierten und des {\"u}berlagerten Elektromyogramms zur Analyse der Muskelerm{\"u}dung}, abstract = {Ziel dieser Studie war das {\"u}berlagerte Elektromyogramm (ueEMG) und das decompositionierte (dEMG) auf deren Reliabilit{\"a}t und Aussagekraft zu {\"u}berpr{\"u}fen. Hierf{\"u}r vollzogen zehn gesunde m{\"a}nnliche Probanden zu drei Testzeitpunkten isometrische Erm{\"u}dungsmessungen. Hintergrund Bei der Messung des ueEMG werden die Motor Units Aktionspotentiale (MUAPS) elektrisch {\"u}berlagert. Physiologische Muskelerm{\"u}dung zeigt sich hier unter anderem in der Ver{\"a}nderung des Frequenzspektrums und der Signalamplitude. Letzteres steigt bei Erm{\"u}dung an, wohingegen die mediane Frequenz (MF) sinkt. Eine weitere M{\"o}glichkeit die Muskelerm{\"u}dung mittels Oberfl{\"a}chen-EMG zu ermitteln ist die Anwendung des dEMGs. Dieses erm{\"o}glicht mithilfe einer Mustererkennungssoftware einzelne MUAPS zu erkennen. Studien zeigten, dass aktive Motor Units (MU) bei wiederholten oder anhaltenden submaximalen Kontraktionen als Muskelerm{\"u}dung ihre Feuerungsrate erh{\"o}hen und neue MU rekrutiert werden. Bisher wurden diese Methoden jeweils einzeln betrachtet. Um sicherzustellen welcher Ansatz f{\"u}r klinische Daten geeigneter ist, wurden Datens{\"a}tze zu beiden Methoden gleichzeitig generiert und hinsichtlich ihrer Aussagekraft und Wiederholbarkeit mit statistischen Mitteln verglichen.}, subject = {Elektromyogramm}, language = {de} }
