The objective of this work is to relate muscle effort distributions to the trajectory and resistance settings of a robotic exercise and rehabilitation machine. Muscular effort distribution, representing the participation of each muscle in the training activity, was measured with electromyography sensors (EMG) and defined as the individual activation divided by the total muscle group activation. A four degrees-of-freedom robot and its impedance control system are used to create advanced exercise protocols whereby the user is asked to follow a path against the machine's neutral path and resistance.

We present an approach for real-time model-free optimization of the orientation of the elliptical trajectory. The performance is evaluated in simulation and experimental stages. Our model-free approach is based on the use of Extremum Seeking Control (ESC) as the real-time optimizer.

Article Synopsis
  • - The study explores the use of circulating tumor cells (CTCs) as a non-invasive method to analyze metastatic castration-resistant prostate cancer (mCRPC) when traditional tumor tissue samples are unavailable.
  • - Researchers conducted a global gene expression analysis of CTCs from nine mCRPC patients, identifying 50 genes unique to these tumor cells, some of which were further validated in a larger cohort.
  • - The findings highlight the potential of CTCs for understanding tumor biology and disease progression, particularly noting the involvement of the MYC gene in mCRPC, emphasizing their significance in clinical management.

Introduction: There is a critical need of new surrogate markers for improving the therapeutic selection and monitoring of metastatic prostate cancer patients. Nowadays clinical management of these patients is been driven by biochemical and clinical parameters without enough accuracy to allow a real personalized medicine. The present study was conducted to go insight the molecular profile of circulating tumor cells (CTCs) isolated from advanced metastatic castration-resistant prostate cancer (mCRPC) with the aim of identifying prognostic marker with potential utility for therapy selection and monitoring.
