Hypogravitational Osteoporosis

Osteoporosis: a condition characterized by an absolute amount reduction to a level at which the amount of bone present is able to maintain structural integrity of the bone below it. It is clear that humans have evolved under the gravity "1 G" of the earth. Our musculoskeletal system evolved to help advance the gravitational field with the ability to adapt to various stress, strain, and the needs of available energy requirements. This system consists of bones, a highly specialized dynamic support organization that provides a solid foundation for vertebrates.

Regardless of the mechanism of severe osteoporosis, it is one of the more serious biomedical hazards that lasts with microgravity over a long period of time. Astronauts and astronauts tried various forms of weight-bearing exercise to reduce the space-related osteoporosis. Isometric exercise is not effective, but the use of bungee space suit shows several effects. However, in order to obtain the desired result, it is troublesome to use the bungee space kit every day from 6 to 8 hours, it is troublesome, requires a lot of work, decreases the efficiency and proves to prevent low severe osteoporosis It is not practical except to do. Theoretical principle

Osteoporosis Osteoporosis is a bone disease. The osteoporotic human bones are very fragile and fragile. Osteoporosis is a concern for all postmenopausal women, especially people living with HIV. In women infected with HIV (and men), osteoporosis can occur at a young age. Some HIV drugs increase the risk of osteoporosis. Learn more about AIDS and osteoporosis

Osteoporosis Osteoporosis in patients with Werner syndrome is abnormal, especially because it affects long bones. In contrast, osteoporosis during normative senescence is preferentially related to vertebral bodies, especially women. A characteristic osteolytic lesion of the distal joint of the finger was observed on the X-ray film. There is controversy about the degree of involvement of the neuro-brain. People with Werner's syndrome may have central nervous system complications of arteriosclerosis, but they do not appear to be unusually sensitive to Alzheimer's disease. Cognitive changes are not usually observed. Diffuse changes observed in brain MRI of some people deserve further study in the study

There are also some important evidence from rodent studies that seems to suggest that a reduction in osteogenesis contributes to severe osteoporosis. MD, a member of NASA's Life Sciences Advisory Committee, says, "Early pathological events after the astronaut entered zero gravity condition occurred in the bone itself, mineral homeostasis and changes in calcitonin were secondary Some aspects stimulate bone resorption by altering the biomedical field or by altering the tension and pressure distribution of the bone cells themselves The gravity and muscle tension on the skeletal system is a function of bone crystal to bone crystal It causes the friction of the bioelectric field, which leads to a bioelectrical field.The mechanism of action may stimulate bone cells and affect bone remodeling. "In the early mission, X-ray density measurements are used to measure flight We measured front and rear weight bones.
