Purpose: PAX-genes encode transcriptional factors important during embryogenesis. They are characterized by the presence of a highly conserved DNA-binding domain, the Paired box. PAX6-gene mutations have been identified in Aniridia and Peters anomaly. Our aim is to map PAX6 gene expression on human embryonic tissue sections at the cellular level.Methods: We studied, by in situ hybridization, the...
Energy consumption and blood flow allocations were studied in human subjects who were induced to stand and walk in a bent-head, bent-knee way, which is one of the different bipedal behaviours that could be considered for the posture and locomotion of Australopithecus afarensis. In these subjects oxygen consumption was intermediate between modern humans standing/walking normally and humans standing/walking...
