Geochemical studies of Wyoming Precambrian graywackes derived from continental crust older than 3.2 x 10(9) years indicate that their source area was at least as highly differentiated as most younger Precambrian crust. The composition of this early crust (approximately that of calcium-rich granite) is not unlike that o…

INTRODUCTION: There is a recognized increase of lifelong surgery risk in Crohn disease (CD). Outcome data concerning surgery in children, particularly in the biological era, are limited. AIM: To characterize the clinical profile and the clinical outcome in children and adolescents with CD who underwent surgical interv…

Molecular evidence indicates that the last common ancestor of the genus Pan and the hominin clade existed between 8 and 4 million years ago (Ma). The current fossil record indicates the Pan-Homo last common ancestor existed at least 5 Ma and most likely between 6 and 7 Ma. Together, the molecular and fossil evidence ha…
