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{Kuba, author = {Kuba, Markus}, title = {A Note on the generating function of p-Bernoulli numbers}, series = {Quaestiones Mathematicae}, journal = {Quaestiones Mathematicae}, subject = {Mathematics}, language = {en} } @article{TeschlUnterkoflerMochalskietal., author = {Teschl, Susanne and Unterkofler, Karl and Mochalski, Pawel and Teschl, Gerald and Ager, C. and Mayhew, C.A. and King, Julian}, title = {Modeling-based determination of physiological parameters of systemic VOCs by breath gas analysis, part 2.}, series = {Journal of Breath Research}, volume = {12}, journal = {Journal of Breath Research}, subject = {Breath}, language = {en} } @article{SchandaKeiblHeimeletal., author = {Schanda, Jakob and Keibl, Claudia and Heimel, Patrick and Monforte, Xavier and Feichtinger, Xaver and Teuschl, Andreas and Baierl, Andreas and Muschitz, Christian and Redl, Heinz and Fialka, Christian and Mittermayr, Rainer}, title = {Zoledronic Acid Substantially Improves Bone Microarchitecture and Biomechanical Properties After Rotator Cuff Repair in a Rodent Chronic Defect Model}, series = {Am J Sports Med}, volume = {2020 Jul}, journal = {Am J Sports Med}, number = {48 (9)}, pages = {2151 -- 2160}, abstract = {Background: Bone mineral density at the humeral head is reduced in patients with chronic rotator cuff tears. 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. Maximum load to failure rates on the operated side were higher in the intervention group (P < .001). Cortical thickness positively correlated with higher maximum load to failure rates in the intervention group (r = 0.69; P = .026). Histological assessment revealed increased bone formation in the intervention group. Conclusion: Single-dose therapy of zoledronic acid provided an improvement of bone microarchitecture at the humeral head as well as an increase of maximum load to failure rates after transosseous reconstruction of chronic rotator cuff lesions in rats. Clinical relevance: Zoledronic acid improves bone microarchitecture as well as biomechanical properties after reconstruction of chronic rotator cuff tears in rodents.

In its simplest form, this is done by subcutaneous material implantation and subsequent vessel counting which usually omits spatial data. 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. In summary, a simple implantation model to study in vivo vascularization with only a minimal workload attached was enhanced to include morphologic data of the emerging vascular tree.}, subject = {Tissue Engineering}, language = {en} } @article{BerkovitchCohenPeledetal., author = {Berkovitch, Yulia and Cohen, Talia and Peled, Eli and Schmidhammer, Robert and Hildner, Florian and Teuschl, Andreas and Wolbank, Susanne and Yelin, Dvir and Redl, Heinz and Seliktar, Dror}, title = {Hydrogel composition and laser micropatterning to regulate sciatic nerve regeneration.}, series = {Journal of Tissue Engineering and Regenerative Medicine}, journal = {Journal of Tissue Engineering and Regenerative Medicine}, pages = {1049 -- 1061}, abstract = {Treatment of peripheral nerve injuries has evolved over the past several decades to include the use of sophisticated new materials endowed with trophic and topographical cues that are essential for in vivo nerve fibre regeneration.

The provisional nerve growth conduits were composed of either natural fibrin or adducts of synthetic polyethylene glycol and fibrinogen or gelatin. A photo-patterning technique was further applied to these 3D hydrogel biomaterials, in the form of laser-ablated microchannels, to provide contact guidance for unidirectional growth following sciatic nerve injury. We tested the regeneration capacity of subcritical nerve gap injuries in rats treated with photo-patterned materials and compared these with injuries treated with unpatterned hydrogels, either stiff or compliant. Among the factors tested were shear modulus, biological composition, and micropatterning of the materials.

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).

The objective of this study is to investigate to what extent the new measurement method of surface gloss is applicable to describe human gloss perception, in other words, to validate the new method. In order to analyse the concordance of the new methodology with human perception, 113 na{\"i}ve observers had to rank the glossiness of eight series of black and white samples.

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.

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.

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} } @article{BellChaloupkaRisser, author = {Bell, Daniel and Chaloupka-Risser, Christine}, title = {Demenz und Mobilit{\"a}t}, series = {Psychologie in {\"O}sterreich 1 \& 2}, volume = {2018}, journal = {Psychologie in {\"O}sterreich 1 \& 2}, number = {Volume 38}, subject = {Dementia}, language = {de} } @article{VotziHimmelstossErtl, author = {Votzi, Helmut and Himmelstoß, Felix and Ertl, Hans}, title = {Active Hybrid Filter Applied with a Multi-Cell Switch-Mode Power Amplifier}, series = {Power Electronics and Motion Control PEMC 2018, 27-29 August 2018, Budapest, Hungary}, journal = {Power Electronics and Motion Control PEMC 2018, 27-29 August 2018, Budapest, Hungary}, subject = {Amplifier}, language = {en} } @article{MuehleisenEderVoronkoetal., author = {Muehleisen, Wolfgang and Eder, Gabriele C. and Voronko, Yuliya and Spielberger, Markus and Sonnleitner, Horst and Kn{\"o}bl, Karl and Ebner, Rita and Ujvari, Guszt{\´a}v and Hirschl, Christina}, title = {Outdoor detection and visualization of hailstorm damages of photovoltaic plants}, series = {Renewable Energy}, journal = {Renewable Energy}, number = {118}, pages = {138 -- 145}, subject = {Photovoltaics}, language = {en} } @article{BellWolfEberlPosch, author = {Bell, Daniel and Wolf-Eberl, Susanne and Posch, Patrick}, title = {Dementia and mobility - issues, needs and solutions}, series = {Transactions on Transport Sciences}, volume = {2018}, journal = {Transactions on Transport Sciences}, number = {Vol. 9, Issue 1}, abstract = {Structural transition in Austrian society in the larger context of demographic change and growing demands on infrastructure, organization and planning in the public sphere have been discussed profusely in recent years in the context of some projects. While a number of national and international research projects especially focussed on the older age groups and their requirements for staying mobile by developing solutions on the individual, technological and infrastructural level, solutions for people who suffer from cognitive impairment as a result of dementia are still missing. The Austrian research project KOMPETENZ takes the first step in identifying the requirements that people with dementia, their caregivers and other relevant stakeholders in this context have towards public space in order to be able to maintain physical mobility of people affected by dementia. One of the main outcomes of the project included an assessment methodology linking barriers and collective mobility needs to high potential solutions, which supports all relevant stakeholders in the process.}, subject = {Mobility}, language = {en} }
