Techniques and routines designed to prevent or reverse unwanted effects of weightlessness experienced during actual and simulated space flight, including physiologic changes related to removal of gravitational loading. Specific measures include creation of artificial gravity, exercise, low-level lower body negative pressure, and use of anti-deconditioning devices.

Word of the day
Procollagen Proline Dioxygenase
- mixed-function oxygenase that catalyzes hydroxylation prolyl-glycyl-containing-peptide, usually in protocollagen, hydroxyprolylglycyl-peptide. The enzyme utilizes molecular oxygen with a concomitant oxidative decarboxylation of 2-oxoglutarate to succinate. EC 1.14.11.2.
