Ontogeny of the Human Pelvis [PDF]
The Anatomical Record, 2017 ABSTRACTThe human pelvis has evolved over time into a remarkable structure, optimised into an intricate architecture that transfers the entire load of the upper body into the lower limbs, while also facilitating bipedal movement. The pelvic girdle is composed of two hip bones, os coxae, themselves each formed from the gradual fusion of the ischium ...

Growth of Mycobacterium tuberculosis in vivo segregates with host macrophage metabolism and ontogeny
Journal of Experimental Medicine, 2018 To understand how infection by Mycobacterium tuberculosis (Mtb) is modulated by host cell phenotype, we characterized those host phagocytes that controlled or supported bacterial growth during early infection, focusing on the ontologically distinct ...
