The effects of ESWT on muscle-in-vein conduits (MVCs) have also not been investigated yet. This study aimed to evaluate the effects of ESWT after repair of the rat median nerve with either autografts (ANGs) or MVCs. In male Lewis rats, a 7 mm segment of the right median nerve was reconstructed either with an ANG or an MVC. For each reconstructive technique, one group of animals received one application of ESWT while the other rats served as controls. The animals were observed for 12 weeks, and nerve regeneration was assessed using computerized gait analysis, the grasping test, electrophysiological evaluations and histological quantification of axons, blood vessels and lymphatic vasculature. Here, we provide for the first time a comprehensive analysis of ESWT effects on nerve regeneration in a rat model of median nerve injury. Furthermore, this study is among the first reporting the quantification of lymphatic vessels following peripheral nerve injury and reconstruction in vivo. While we found no significant direct positive effects of ESWT on peripheral nerve regeneration, results following nerve repair with MVCs were significantly inferior to those after ANG repair.}, subject = {Tissue Engineering}, 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} }
