Comparative analysis of metabolic and structural shifts in rats following 14 days of microgravity aboard biosatellite Cosmos-2044 and their tail-suspended synchronous controls gave evidence that suspension-induced deprivation of hind limbs of support loading yields inherent to microgravity shifts the endocrine control of energy, plastic, and mineral metabolism. The conclusion has been drawn that tail-suspension can be used as a model of the microgravity effects on the musculoskeletal apparatus and the endocrine systems controlling metabolism in muscles and bones.

Effectiveness of Integrated Digital Solutions to Empower Older Adults in Aspects Related to Their Health: Systematic Review and Meta-Analysis.
J Med Internet Res
January 2025
School of Health Sciences, Center for Health Technology and Services Research, University of Aveiro, Aveiro, Portugal.
Background: Digital solutions, such as mobile apps or telemonitoring devices, are frequently considered facilitators in the process of empowering older adults, but they can also act as a source of digital exclusion or disempowerment if they are not adequate for older adults' needs and characteristics.
Objective: This study aimed to synthesize and critically evaluate existing evidence on the effectiveness of integrated digital solutions that enable interaction for empowering older adults in aspects related to their health and to explore potential factors (eg, type of technology, participants' characteristics) impacting effectiveness.
Methods: A systematic search was carried out in PubMed, ScienceDirect, SCOPUS, EBSCO, and SciELO using a combination of terms informed by previous reviews on empowerment.
