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. These results need to be verified in clinical investigations.}, subject = {Tissue Engineering}, 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{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. 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} } @misc{SlezakRoseHercheretal., author = {Slezak, Paul and Rose, Roland and Hercher, David and Weihs, Anna and Fuchs, Christiane and Redl, Heinz and Mittermayr, Rainer and Slezak, Cyrill}, title = {Tracking therapeutic shockwaves and their impact on regeneration}, subject = {Shockwave Therapy}, language = {en} } @inproceedings{FuchsWeihsSzwarcetal., author = {Fuchs, Christiane and Weihs, Anna and Szwarc, Dorota and Mittermayr, Rainer and R{\"u}nzler, Dominik and Teuschl, Andreas}, title = {Shock wave treatment of muscle (stem) cells - a new implementation for regeneration}, series = {Proceedings of the 20th International Congress of the ISMST}, booktitle = {Proceedings of the 20th International Congress of the ISMST}, subject = {Shockwave treatment}, language = {en} } @misc{FuchsWeihsSzwarcetal., author = {Fuchs, Christiane and Weihs, Anna and Szwarc, Dorota and Mittermayr, Rainer and R{\"u}nzler, Dominik and Teuschl, Andreas}, title = {Shock wave treatment of muscle (stem) cells - a new implementation for regeneration}, subject = {Shockwave treatment}, language = {en} } @misc{FuchsWeihsTeuschletal., author = {Fuchs, Christiane and Weihs, Anna and Teuschl, Andreas and Hartinger, Joachim and Slezak, Paul and Mittermayr, Rainer and Redl, Heinz and Junger, Wolfgang and Sitte, Harald and R{\"u}nzler, Dominik}, title = {Shockwave Treatment Enhances Proliferation and Improves Wound Healing via Purinergic Signaling Linked ERK 1/2 Pathways}, subject = {Shockwave treatment}, language = {en} } @misc{FuchsWeihsTeuschletal., author = {Fuchs, Christiane and Weihs, Anna and Teuschl, Andreas and Hartinger, Joachim and Slezak, Paul and Mittermayr, Rainer and Redl, Heinz and Junger, Wolfgang and Sitte, Harald and R{\"u}nzler, Dominik}, title = {Shockwave Treatment Augments Proliferation and Improves Wound Healing via Purinergic Signaling Linked ERK 1/2 Pathways}, subject = {Shockwave treatment}, language = {en} } @misc{WeihsFuchsTeuschletal., author = {Weihs, Anna and Fuchs, Christiane and Teuschl, Andreas and Hartinger, Joachim and Slezak, Paul and Mittermayr, Rainer and Redl, Heinz and Junger, Wolfgang and Sitte, Harald and R{\"u}nzler, Dominik}, title = {Shockwave treatment activates Erk1/2 pathways predominantly via P2Y receptor involvement}, subject = {Shockwave}, language = {en} } @article{WeihsFuchsTeuschletal., author = {Weihs, Anna and Fuchs, Christiane and Teuschl, Andreas and Hartinger, Joachim and Slezak, Paul and Mittermayr, Rainer and Redl, Heinz and Junger, Wolfgang and Sitte, Harald and R{\"u}nzler, Dominik}, title = {Shock Wave Treatment Enhances Cell Proliferation and Improves Wound Healing by ATP Release-coupled Extracellular Signal-regulated Kinase (ERK) Activation}, series = {The Journal of biological chemistry}, journal = {The Journal of biological chemistry}, subject = {Shockwave}, language = {de} } @article{SchuhHeherWeihsetal., author = {Schuh, Christina and Heher, Philipp and Weihs, Anna and Asmita, Banerjee and Wolbank, Susanne and Mittermayr, Rainer and Redl, Heinz and R{\"u}nzler, Dominik and Teuschl, Andreas}, title = {Adipose derived stem cells respond to in vitro extracorporeal shockwave treatment with increased stemness and multipotency}, series = {New Biotechnology}, journal = {New Biotechnology}, subject = {Shockwave}, language = {en} } @article{AshmwePosaRuehrnoessletal., author = {Ashmwe, Mohamed and Posa, Katja and R{\"u}hrn{\"o}ßl, Alexander and Heinzel, Johannes Christoph and Heimel, Patrick and Mock, Michael and Sch{\"a}dl, Barbara and Keibl, Claudia and Couillard-Despres, Sebastien and Redl, Heinz and Mittermayr, Rainer and Hercher, David}, title = {Effects of Extracorporeal Shockwave Therapy on Functional Recovery and Circulating miR-375 and miR-382-5p after Subacute and Chronic Spinal Cord Contusion Injury in Rats}, series = {Biomedicines}, volume = {2022}, journal = {Biomedicines}, number = {10(7)}, doi = {https://doi.org/10.3390/biomedicines10071630}, pages = {1630}, abstract = {Extracorporeal shockwave therapy (ESWT) can stimulate processes to promote regeneration, including cell proliferation and modulation of inflammation. Specific miRNA expression panels have been established to define correlations with regulatory targets within these pathways. This study aims to investigate the influence of low-energy ESWT-applied within the subacute and chronic phase of SCI (spinal cord injury) on recovery in a rat spinal cord contusion model. Outcomes were evaluated by gait analysis, µCT and histological analysis of spinal cords. A panel of serum-derived miRNAs after SCI and after ESWT was investigated to identify injury-, regeneration- and treatment-associated expression patterns. Rats receiving ESWT showed significant improvement in motor function in both a subacute and a chronic experimental setting. This effect was not reflected in changes in morphology, µCT-parameters or histological markers after ESWT. Expression analysis of various miRNAs, however, revealed changes after SCI and ESWT, with increased miR-375, indicating a neuroprotective effect, and decreased miR-382-5p potentially improving neuroplasticity via its regulatory involvement with BDNF. We were able to demonstrate a functional improvement of ESWT-treated animals after SCI in a subacute and chronic setting. Furthermore, the identification of miR-375 and miR-382-5p could potentially provide new targets for therapeutic intervention in future studies.}, subject = {Tissue Engineering}, 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} }
