Radiation therapy is one of the most effective and indispensable treatment modalities for cancer patients. Known tissue complications caused by radiation-induced stem cell depletion, may result in structural and functional alterations of the surrounding matrix. Although, studies have demonstrated that ionizing radiation can induce apoptosis and senescence, little is known about the effects of therapeutic irradiation concerning the commitment of mesenchymal stem cells to the os...

Multiple myeloma (MM) is associated with lytic bone destruction leading to high fracture incidence in the vertebrae. Accurate assessment of fracture risk is required for physicians to determine the necessity for surgery. This risk is currently determined by examining lesion size or number; however, this method does not consider the biomechanical attributes of the bone. Finite element (FE) modelling can simulate mechanical loading on vertebral bodies, and estimate mechanical in...
