Bone collagen tensile properties of the aging human proximal femur
Autor: Stefan Bracher, Benjamin Voumard, Mathieu Simon, Tatiana Kochetkova, Michael Pretterklieber, Philippe Zysset
Publikováno v: Bone Reports, Vol 21, Iss , Pp 101773- (2024)
Despite the dominant role of bone mass in osteoporotic fractures, aging bone tissue properties must be thoroughly understood to improve osteoporosis management. In this context, collagen content and integrity are considered important factors, althoug

Tensile Mechanical Properties of Dry Cortical Bone Extracellular Matrix: A Comparison Among Two Osteogenesis Imperfecta and One Healthy Control Iliac Crest Biopsies
Autor: Michael Indermaur, Daniele Casari, Tatiana Kochetkova, Bettina M. Willie, Johann Michler, Jakob Schwiedrzik, Philippe Zysset
Publikováno v: JBMR Plus, Vol 7, Iss 12, Pp n/a-n/a (2023)
Abstract Osteogenesis imperfecta (OI) is a genetic, collagen‐related bone disease that increases the incidence of bone fractures. Still, the origin of this brittle mechanical behavior remains unclear. The extracellular matrix (ECM) of OI bone exhib

Monitoring the Induction of Heat Shock Factor 1/Heat Shock Protein 70 Expression following 17-Allylamino-Demethoxygeldanamycin Treatment by Positron Emission Tomography and Optical Reporter Gene Imaging
Autor: Mikhail Doubrovin, Jian T. Che, Inna Serganova, Ekaterina Moroz, David B. Solit, Lyudmila Ageyeva, Tatiana Kochetkova, Nagavarakishore Pillarsetti, Ronald Finn, Neal Rosen, Ronald G. Blasberg
Publikováno v: Molecular Imaging, Vol 11 (2012)
The cell response to proteotoxic cell stresses is mediated primarily through activation of heat shock factor 1 (HSF1). This transcription factor plays a major role in the regulation of the heat shock proteins (HSPs), including HSP70. We demonstrate t

Publikováno v: Kochetkova, Tatiana; Groetsch, Alexander; Indermaur, Michael; Peruzzi, Cinzia; Remund, Stefan; Neuenschwander, Beat; Bellon, Benjamin; Michler, Johann; Zysset, Philippe; Schwiedrzik, Jakob (2022). Assessing minipig compact jawbone quality at the microscale. Journal of the mechanical behavior of biomedical materials, 134, p. 105405. Elsevier 10.1016/j.jmbbm.2022.105405
Preclinical studies often require animal models for in vivo experiments. Particularly in dental research, pig species are extensively used due to their anatomical similarity to humans. However, there is a considerable knowledge gap on the multiscale
