A novel device to preserve physical activities of daily living in healthy older people
Wolfram Haslinger, Lisa Müller, Nejc Šarabon, Christian Raschner, Helmut Kern, Stefan Loefler, 2015, original scientific article

Abstract: Objective: To determine the effectiveness of exercise in improving sensorimotor function and functional performance as crucial part of activities of daily living in healthy older adults. Design: RCT. Setting: Laboratory. Participants: 39 subjects (M = 71.8 years, range: 61%89 years). Intervention: Task oriented visual feedback balance training. Primary outcome measure: Timed up & go (TUG). Secondary outcome measures: Chair stand test (CST), self-paced walk test, maximum isometric torque, quiet stand posturography and dynamic balance (DB). Results: Post intervention comparison of the treatment group (TG) and control group (CG) showed better TUG (p < .01), CST (p < .001) and DB (p < .025) for the TG. Pre%post intervention comparison of the TG showed better clinically relevant outcomes in TUG (p < .001), CST (p < .001) and DB (p < .001). Conclusion: Active driven visual feedback balance training is effective in improving functional performance and dynamic balance in older adults.

Endoglin (CD105) silencing mediated by shRNA under the control of Endothelin-1 promoter for targeted gene therapy of Melanoma

Abstract: Endoglin (CD105), a transforming growth factor (TGF)-% coreceptor, and endothelin-1, a vasoconstrictor peptide, are both overexpressed in tumor endothelial and melanoma cells. Their targeting is therefore a promising therapeutic approach for melanoma tumors. The aim of our study was to construct a eukaryotic expression plasmid encoding the shRNA molecules against CD105 under the control of endothelin-1 promoter and to evaluate its therapeutic potential both in vitro in murine B16F10-luc melanoma and SVEC4-10 endothelial cells and in vivo in mice bearing highly metastatic B16F10-luc tumors. Plasmid encoding shRNA against CD105 under the control of the constitutive U6 promoter was used as a control. We demonstrated the antiproliferative and antiangiogenic effects of both plasmids in SVEC4-10 cells, as well as a moderate antitumor and pronounced antimetastatic effect in B16F10-luc tumors in vivo. Our results provide evidence that targeting melanoma with shRNA molecules against CD105 under the control of endothelin-1 promoter is a feasible and effective treatment, especially for the reduction of metastatic spread.
