A 3-month-old female infant who presented with patent sagittal suture and loss of weight is described. Physical examination revealed a large sagittal and metopic suture showing delayed closure, a high-arched palate, saddle nose, hypertelorism and nonpalpable edges of the bilateral clavicles. The clavicles also showed undue mobility. Radiological investigations of the cranial skeletal abnormalit...

Previous studies have referred to the degree of dorsal canting of the base of the proximal phalanx as an indicator of human-like metatarsophalangeal joint function and thus a diagnostic trait of habitual bipedality in the fossil record. Here, we used a simple method to investigate differences in forefoot function on a finer scale. Building on Duncan et al.'s (Am J Phys Anthropol 93 [1994] 67-81...

In this report we employed double-knock-out mouse embryos and fetuses (designated as Myf5-/-: MyoD-/- that completely lacked striated musculature to study bone development in the absence of mechanical stimuli from the musculature and to distinguish between the effects that static loading and weight-bearing exhibit on embryonic development of skeletal system. We concentrated on development of th...
