Evaluating countermeasures in spaceflight analogs.
Countermeasures are defined as solutions to prevent the undesirable physiologic outcomes associated with spaceflight. Spaceflight analogs provide a valuable opportunity for the evaluation of countermeasures because they allow for the evaluation of more subjects, more experimental control, and are considerably less expensive than actual spaceflight. The various human analogs have differing stren...
متن کاملPharmacological Countermeasures to Spaceflight-Induced Alterations of the Immune System
Opportunities for microbes to establish infections are enhanced under spacefl ight conditions because space travel stimulates their growth (Chap. 15 ) and has a negative impact on immune functions. Indeed, it has been shown that spacefl ight affects lymphoid organs (Gridley et al. 2003 ; Baqai et al. 2009 ) and induces variations in peripheral blood leukocyte subsets (Chap. 9 ). Neutrophil, mon...
متن کاملMuscle Atrophy Induced by Mechanical Unloading: Mechanisms and Potential Countermeasures
Prolonged periods of skeletal muscle inactivity or mechanical unloading (bed rest, hindlimb unloading, immobilization, spaceflight and reduced step) can result in a significant loss of musculoskeletal mass, size and strength which ultimately lead to muscle atrophy. With advancement in understanding of the molecular and cellular mechanisms involved in disuse skeletal muscle atrophy, several diff...
متن کاملToxic-metabolic, nutritional, and medicinal-induced disorders of cerebellum.
The human cerebellum is composed of 2 hemispheres and a narrow medial section (vermis). Three pairs of dense fiber bundles (peduncles) connect the cerebellum to the brain. The cerebellum possesses widespread outgoing connections. Insult can result in neurologic deficits, including ataxia, hypotonia, dysarthria, and ocular motility problems. It is particularly susceptible to toxic effects of met...
متن کاملConsequences of cardiovascular adaptation to spaceflight: implications for the use of pharmacological countermeasures.
There is little evidence obtained from space flight to support the notion that occurrence of cardiac dysrhythmias, impaired cardiac and vascular function, and manifestation of asymptomatic cardiovascular disease represent serious risks during space flight. Therefore, the development of orthostatic hypotension and instability immediately after return from spaceflight probably reflect the most si...
