Bioinformatics approaches have proven useful in understanding biological responses to spaceflight. Spaceflight experiments remain resource intensive and rare. One outstanding issue is how to maximize scientific output from a limited number of omics datasets from traditional animal models including nematodes, fruit fly, and rodents. The utility of omics data from invertebrate models in anticipating mammalian responses to spaceflight has not been fully explored. Hence, we performed comparative analyses of transcriptomes of soleus and extensor digitorum longus (EDL) in mice that underwent 37 days of spaceflight. Results indicate shared stress responses and altered circadian rhythm. EDL showed more robust growth signals …

Musculoskeletal models offer a convenient method to non-invasively study human development, function, and pathologies. While adult musculoskeletal models have been extensively studied [1], infant populations have been widely underserved. However, understanding infant joint biomechanics during the first year of life is vital considering abnormal loads may be detrimental to growth and development. Joint moments from an infant musculoskeletal model could help assess pathologies such as developmental dysplasia of the hip (DDH). Previous computational studies involving infant biomechanics [2, 3] lacked the modeling of active muscle response which may affect musculoskeletal development [4]. As such, the purpose of this study is …
