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.

Matrix elasticity, for instance, is known to guide stem cell differentiation, influence healing processes and modulate extracellular matrix (ECM) deposition needed for tissue development and maintenance. 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. Results show that fibrin hydrogels of 30 kPa Young's modulus best guide chondrocyte redifferentiation resulting in a native-like morphology as well as induces the synthesis of physiologic ECM constituents such as glycosaminoglycans (sGAG) and collagen type II. This comprehensive study sheds light onto the mechanobiological impact of matrix elasticity on formation and maintenance of articular cartilage and thus represents a major step toward meeting the need for advanced in vitro tissue models to study both re- and degeneration of articular cartilage.}, subject = {Tissue Engineering}, language = {en} } @inproceedings{Mally, author = {Mally, Franziska}, title = {In-Shoe Plantar Pressure Measurement—Influence of Insole Placement on Selected Parameters during Running.}, series = {ISEA 2020 Online - Proceedings 2020, 49(1)}, booktitle = {ISEA 2020 Online - Proceedings 2020, 49(1)}, pages = {50 -- 50}, subject = {Sports Equipment Technologies}, language = {en} } @inproceedings{WiessnerPraherLiousiaetal., author = {Wießner, Katharina and Praher, Daniela and Liousia, Varvara and Gepp, Barbara and Leitner, Rita and R{\"u}nzler, Dominik}, title = {Testing the acute toxicity of an alternative to Glyphosate - Pelargonic acid}, series = {SETAC Europe 30th Annual Meeting - Online}, booktitle = {SETAC Europe 30th Annual Meeting - Online}, organization = {Society of Environmental Toxicology and Chemistry (SETAC)}, abstract = {Glyphosate-based herbicides were used as plant protection product globally for several decades. 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. However, more investigations have to be done in order to analyse if the acidic form is more toxic than the saponified form. Furthermore, detailed ecotoxicological risk assessments and an evaluation of the genotoxicity of both herbicides has to be performed before any conclusion can be drawn.

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{RoesslerHoeller, author = {R{\"o}ssler, Peter and H{\"o}ller, Roland}, title = {Programmable Logic Devices - Key Components for Today's and Tomorrow's Electronic-Based Systems}, series = {e\&i (Elektrotechnik und Informationstechnik), Volume 137, Issue 1, 2020}, volume = {Vol. 137, 2020}, journal = {e\&i (Elektrotechnik und Informationstechnik), Volume 137, Issue 1, 2020}, number = {Issue 1, 2020}, pages = {7}, subject = {Programmable Logic Devices}, language = {en} } @article{OtrebskiRauerEngelhardtNowitzkietal., author = {Otrebski, Richard and Rauer, Johannes and Engelhardt-Nowitzki, Corinna and Kryvinska, Natalia and Aburaia, Mohamed and Pospisil, Dominik}, title = {Flexibility Enhancements in Digital Manufacturing by means of Ontological Data Modeling}, series = {International Journal of Ubiquitous Systems and Pervasive Networks (JUSPN)}, journal = {International Journal of Ubiquitous Systems and Pervasive Networks (JUSPN)}, number = {Volume 12, Issue 2}, subject = {Communication Modeling}, language = {en} } @article{HuFengZhangetal., author = {Hu, Qingxi and Feng, Di and Zhang, Haiguang and Yao, Yuan and Aburaia, Mohamed and Lammer, Herfried}, title = {Oriented to Multi-Branched Structure Unsupported 3D Printing Method Research}, series = {Materials, vol. 13, no. 9, p. 2023, Apr. 2020}, journal = {Materials, vol. 13, no. 9, p. 2023, Apr. 2020}, subject = {Structure}, language = {en} } @article{EngelhardtNowitzkiAburaiaRauer, author = {Engelhardt-Nowitzki, Corinna and Aburaia, Mohamed and Rauer, Johannes}, title = {Research-based teaching in digital manufacturing and robotics - the Digital Factory at the UAS Technikum Wien as an exemplary case}, series = {CLF2020 TU Graz}, journal = {CLF2020 TU Graz}, subject = {Digital Manufacturing}, language = {en} } @article{MandlOestlinDawodetal., author = {Mandl, Thomas and {\"O}stlin, Christofer and Dawod, Ibrahim E. and Brodmerkel, Maxim N. and Marklund, Erik G. and Martin, Andrew V. and Timneanu, Nicusor and Caleman, Carl}, title = {Structural Heterogeneity in Single Particle Imaging Using X-ray Lasers}, series = {The Journal of Physical Chemistry Letters}, volume = {2020}, journal = {The Journal of Physical Chemistry Letters}, number = {Volume 11, Issue 15}, pages = {6077 -- 6083}, abstract = {One of the challenges facing single particle imaging with ultrafast X-ray pulses is the structural heterogeneity of the sample to be imaged.

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.

Tires belong to this class of materials. On top, one of their main constitutents, vulcanized rubber, is as elastomer, which cannot be remolten and hence is particularly challenging to put to a new use. Today, the main end-of-life routes of tires and other rubber products are landfilling, incineration in e.g., cement plants, and grinding to a fine powder, generating huge quantities and indicating a lack of sustainable recycling of this valuable material. True feedstock recycling is not feasible for complex mixtures such as tires, but devulcanization can be done to reactivate the cross-linked polymer for material recycling in novel rubber products. Devulcanization, i.e., the breaking up of sulfur bonds by chemical, thermophysical, or biological means, is a promising route that has been investigated for more than 50 years. This review article presents an update on the state-of-the art in rubber devulcanization. The article addresses established devulcanization technologies and novel processes described in the scientific and patent literatures. On the one hand, tires have become high-tech products, where the simultaneous improvement of wet traction, rolling resistance, and abrasion resistance (the so-called "magic triangle") is hard to achieve. On the other hand, recycling and sustainable end-of-life uses are becoming more and more important. It is expected that the public discussion of environmental impacts of thermoplastics will soon spill over to thermosets and elastomers. Therefore, the industry needs to develop and market solutions proactively. Every year, approximately 40 million tons of tires are discarded. Through the devulcanization of end-of-life tires (ELT), it is possible to produce new raw materials with good mechanical properties and a superior environmental footprint over virgin products.

However, a role for ATP release and P2Y receptor signalling in angiogenesis remains poorly defined. Here, we demonstrate that blood vessel growth is controlled by P2Y2 receptors. 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. Our data suggest that P2Y2 receptors have an essential function in angiogenesis, and that P2Y2 receptors present a therapeutic target to regulate blood vessel growth.}, subject = {Angiogenesis}, language = {en} } @inproceedings{WidhalmGoeschkaKastner, author = {Widhalm, Dominik and Goeschka, Karl M. and Kastner, Wolfgang}, title = {SoK: A Taxonomy for Anomaly Detection in Wireless Sensor Networks focused on Node-level Techniques}, series = {Proceedings of 15th International Conference on Availability, Reliability and Security (ARES 2020), 25-28 August 2020, Virtual Event, Ireland}, booktitle = {Proceedings of 15th International Conference on Availability, Reliability and Security (ARES 2020), 25-28 August 2020, Virtual Event, Ireland}, pages = {10}, subject = {anomaly detection}, language = {en} } @article{YalcinHimmelstoss, author = {Yalcin, Faruk and Himmelstoß, Felix}, title = {Buck-type Single-phase AC-AC Active Tracking Voltage Regulator Controlled by an Enhanced Hybrid Control Method}, series = {Sakarya University Journal of Science}, volume = {2021}, journal = {Sakarya University Journal of Science}, number = {25}, pages = {926 -- 937}, subject = {AC-AC regulator}, language = {en} } @article{KrizekLietzeBecketal., author = {Krizek, Gerd Christian and Lietze, Stefanie and Beck, Stefan and Langer, Karin}, title = {Differenzierte Kompetenzmessung mittels eAssessments - Ein Konzept f{\"u}r die Zukunft}, series = {fnma}, journal = {fnma}, subject = {education}, language = {de} }
