Osteocytes and Weightlessness [PDF]
Current Osteoporosis Reports, 2021 Abstract Purpose of Review Osteocytes are considered to be the cells responsible for mastering the remodeling process that follows the exposure to unloading conditions. Given the invasiveness of bone biopsies in humans, both rodents and in vitro culture systems are largely adopted as models for studies in space missions ...

The Effects of Chronic Weightlessness on Limited of Stability and Dynamic Balance in Breath-hold and SCUBA Divers [PDF]
Journal of Paramedical Science and Rehabilitation, 2022 Purpose:Water immersion built a new environment in which weightlessness puts unknown demand on somatosensory system such as altered sensory integration due to the improper proprioception afferent. This condition can lead to an imprecise function of human
